Biological processes are end-directed, that is, teleological. Explaining the physical efficacy of end-directedness continues to be a profound challenge for theoretical biology, especially given its unavoidable implications for our own self-understanding. For a comprehensive theory of life, it is pivotal to bridge our human-centric view of end-directedness, which the social sciences and humanities consider intrinsic to our actions, with the natural sciences' view of actions' in purely physiological terms, especially in terms of thermodynamic tendencies. A comprehensive theory should therefore provide an end-involving account, which illuminates how both physiology and teleology distinctly contribute to behavior generation. Here we introduce the "Participation Criterion": End-involvement in a bodily process entails that, in principle, it is distinguishable from one without end-involvement, specifically in terms of physiologically unpredictable changes in unexplainable variability. To exemplify the difficulty of satisfying this criterion, we critically analyze two theories on the thermodynamic basis of end-directedness. We then propose that "Irruption Theory" points to a way forward because it predicts that bodily processes have an endinvolvement-dependent increase in their entropy rate. This is consistent with evidence of an association between conscious intention and neural fluctuations, is open to further experimental verification, and provides a novel perspective on the role of thermodynamic entropy production in the organism.

Varela's enactive approach to cognitive science has been elaborated into a theoretical framework of agency, sense-making, and sociality, while his key methodological innovationneurophenomenology (NP)-continues to inspire empirical work. We argue that the enactive approach was originally expressed in NP as three core tenets: (1) phenomenological pragmatics, (2) embodied cognition, and (3) conscious efficacy. However, most efforts in NP have focused on applying tenet 1, while tenet 2 has received notably less attention, and there is even explicit distancing from tenet 3. By way of a critical review of four case studies, we show how NP thereby falls short of its full potential. Crucially, it needs to demonstrate that the first-person perspective matters, not only as a source of correlations with third-person data, but because lived experience, as such, makes a difference in its own right to the living body's dynamics. Given that methods for improving subjective reports have become accepted in human neuroscience (tenet 1), and given the increasing availability for recording multiscalar organismic activity during embodied action (tenet 2), we propose it is time to integrate these research strands by using this issue of conscious efficacy as a pivot point (tenet 3). The development of genuinely experience-involving accounts of neurophysiological activity during embodied action holds promise for rebooting neurophenomenology in stronger form.

Cognitive science is lacking conceptual tools to describe how an agent’s motivations, as such, can play a role in the generation of its behavior. The enactive approach has made progress by developing a relaxed naturalism, and by placing normativity at the core of life and mind; all cognitive activity is a kind of motivated activity. It has rejected representational architectures, especially their reification of the role of normativity into localized “value” functions, in favor of accounts that appeal to system-level properties of the organism. However, these accounts push the problem of reification to a higher level of description, given that the efficacy of agent-level normativity is completely identified with the efficacy of non-normative system-level activity, while assuming operational equivalency. To allow normativity to have its own efficacy, a new kind of nonreductive theory is proposed: irruption theory. The concept of irruption is introduced to indirectly operationalize an agent’s motivated involvement in its activity, specifically in terms of a corresponding underdetermination of its states by their material basis. This implies that irruptions are associated with increased unpredictability of (neuro)physiological activity, and they should, hence, be quantifiable in terms of information-theoretic entropy. Accordingly, evidence that action, cognition, and consciousness are linked to higher levels of neural entropy can be interpreted as indicating higher levels of motivated agential involvement. Counterintuitively, irruptions do not stand in contrast to adaptive behavior. Rather, as indicated by artificial life models of complex adaptive systems, bursts of arbitrary changes in neural activity can facilitate the self-organization of adaptivity. Irruption theory therefore, makes it intelligible how an agent’s motivations, as such, can make effective differences to their behavior, without requiring the agent to be able to directly control their body’s neurophysiological processes.

There is an overlooked similarity between three classic accounts of the conditions of object experience from three distinct disciplines. (1) Sociology: the “inversion” that accompanies discovery in the natural sciences, as local causes of effects are reattributed to an observed object. (2) Psychology: the “externalization” that accompanies mastery of a visual–tactile sensory substitution interface, as tactile sensations of the proximal interface are transformed into vision-like experience of a distal object. (3) Biology: the “projection” that brings forth an animal’s Umwelt, as impressions on its body’s sensory surfaces are reconfigured into perception of an external object. This similarity between the effects of scientific practice and interface-use on the one hand, and of sensorimotor interaction on the other, becomes intelligible once we accept that skillful engagement with instruments and interfaces constitutes a socio-material augmentation of our basic perceptual capacity. This enactive interpretation stands in contrast to anti-realism about science associated with constructivist interpretations of these three phenomena, which are motivated by viewing them as the internal mental construction of the experienced object. Instead, it favors a participatory realism: the sensorimotor basis of perceptual experience loops not only through our body, but also through the external world. This allows us to conceive of object experience in relational terms, i.e., as one or more subjects directly engaging with the world. Consequently, we can appreciate scientific observation in its full complexity: it is a socio-materially augmented process of becoming acquainted with the observed object that—like tool-use and perceiving more generally—is irreducibly self, other-, and world-involving.

The social brain hypothesis proposes that enlarged brains have evolved in response to the increasing cognitive demands that complex social life in larger groups places on primates and other mammals. However, this reasoning can be challenged by evidence that brain size has decreased in the evolutionary transitions from solitary to social larger groups in the case of Neolithic humans and some eusocial insects. Different hypotheses can be identified in the literature to explain this reduction in brain size. We evaluate some of them from the perspective of recent approaches to cognitive science, which support the idea that the basis of cognition can span over brain, body, and environment. Here we show through a minimal cognitive model using an evolutionary robotics methodology that the neural complexity, in terms of neural entropy and degrees of freedom of neural activity, of smaller-brained agents evolved in social interaction is comparable to the neural complexity of larger-brained agents evolved in solitary conditions. The nonlinear time series analysis of agents' neural activity reveals that the decoupled smaller neural network is intrinsically lower dimensional than the decoupled larger neural network. However, when smaller-brained agents are interacting, their actual neural complexity goes beyond its intrinsic limits achieving results comparable to those obtained by larger-brained solitary agents. This suggests that the smaller-brained agents are able to enhance their neural complexity through social interaction, thereby offsetting the reduced brain size.

Serotonergic agonist psilocybin is a psychedelic with antidepressant potential. Sleep may interact with psilocybin's antidepressant properties like other antidepressant drugs via induction of neuroplasticity. The main aim of the study was to evaluate the effect of psilocybin on sleep architecture on the night after psilocybin administration. Regarding the potential antidepressant properties, we hypothesized that psilocybin, similar to other classical antidepressants, would reduce rapid eye movement (REM) sleep and prolong REM sleep latency. Moreover, we also hypothesized that psilocybin would promote slow-wave activity (SWA) expression in the first sleep cycle, a marker of sleep-related neuroplasticity. Twenty healthy volunteers (10 women, age 28-53) underwent two drug administration sessions, psilocybin or placebo, in a randomized, double-blinded design. Changes in sleep macrostructure, SWA during the first sleep cycle, whole night EEG spectral power across frequencies in non-rapid eye movement (NREM) and REM sleep, and changes in subjective sleep measures were analyzed. The results revealed prolonged REM sleep latency after psilocybin administration and a trend toward a decrease in overall REM sleep duration. No changes in NREM sleep were observed. Psilocybin did not affect EEG power spectra in NREM or REM sleep when examined across the whole night. However, psilocybin suppressed SWA in the first sleep cycle. No evidence was found for sleep-related neuroplasticity, however, a different dosage, timing, effect on homeostatic regulation of sleep, or other mechanisms related to antidepressant effects may play a role. Overall, this study suggests that potential antidepressant properties of psilocybin might be related to changes in sleep.

The enactive theory of perception hypothesizes that perceptual access to objects depends on the mastery of sensorimotor contingencies, that is, on the know-how of the regular ways in which changes in sensations depend on changes in movements. This hypothesis can be extended into the social domain: perception of other minds is constituted by mastery of self-other contingencies, that is, by the know-how of the regular ways in which changes in others' movements depend on changes in one's movements. We investigated this proposal using the perceptual crossing paradigm, in which pairs of players are required to locate each other in an invisible one-dimensional virtual space by using a minimal haptic interface. We recorded and analyzed the real-time embodied social interaction of 10 pairs of adult participants. The results reveal a process of implicit perceptual learning: on average, clarity of perceiving the other's presence increased over trials and then stabilized. However, a clearer perception of the other was not associated with correctness of recognition as such, but with both players correctly recognizing each other. Furthermore, the moments of correct mutual recognition tended to happen within seconds. The fact that changes in social experience can only be explained by the successful performance at the level of the dyad, and that this veridical mutual perception tends toward synchronization, lead us to hypothesize that integration of neural activity across both players played a role.

The association between neural oscillations and functional integration is widely recognized in the study of human cogni-tion. Large-scale synchronization of neural activity has also been proposed as the neural basis of consciousness. Intriguingly, a growing number of studies in social cognitive neuroscience reveal that phase synchronization similarly appears across brains during meaningful social interaction. Moreover, this inter-brain synchronization has been associated with subjective reports of social connectedness, engagement, and cooperativeness, as well as experiences of social cohesion and 'self-other merging'. These findings challenge the standard view of human consciousness as essentially first-person singular and private. We therefore revisit the recent controversy over the possibility of extended consciousness and argue that evidence of inter-brain synchronization in the fastest frequency bands overcomes the hitherto most convincing sceptical position. If this proposal is on the right track, our understanding of human consciousness would be profoundly transformed , and we propose a method to test this proposal experimentally.

Enactive cognitive science (ECS) and ecological psychology (EP) agree that active movement is important for perception, but they remain ambiguous regarding the precise role of agency. EP has focused on the notion of sensorimotor invariants, according to which bodily movements play an instrumental role in perception. ECS has focused on the notion of sensorimotor contingencies, which goes beyond an instrumental role because skillfully regulated movements are claimed to play a constitutive role. We refer to these two hypotheses as instrumental agency and constitutive agency, respectively. Evidence comes from a variety of fields, including neural, behavioral, and phenomenological research, but so far with confounds that prevent an experimental distinction between these hypotheses. Here we advance the debate by proposing a novel double-participant setup that aims to isolate agency as the key variable that distinguishes bodily movement in active and passive conditions of perception. We pilot this setup with a psychological study of width discrimination using the Enactive Torch, a haptic sensory substitution device. There was no evidence favoring the stronger hypothesis of constitutive agency over instrumental agency. However, we caution that during debriefing several participants reported using cognitive strategies that did not rely on spatial perception. We conclude that this approach is a viable direction for future research, but that greater care is required to establish and confirm the desired modality of first-person experience.

Most of the little we know about the use of psychoactive plants in pre-Hispanic Mexico comes from post-contact sources, and from the occasional archaeological artefact that is suggestive of cultural continuity into the deeper past (Nesvig 2017). One of the most prominent genera in this context is Datura, which has significant implications for many indigenous cultures and remains widespread in traditional medicine. We know from accounts produced from the early 16th century onwards that the Aztecs considered several species sacred. However, it is unclear how much deeper into the pre-Hispanic past this role extends, because the prehistoric roots of Datura use are poorly understood throughout the Americas, and archaeobotanical evidence is scant (Rafferty 2018). Here it is proposed that botanical motifs in mural paintings of ancient Teotihuacan represent Datura thorn apples. This extends cultural continuity back to this urban center, which was at its height from about 150 to 550 CE (Cowgill 2015), and thus preceded the Aztec empire by a millennium.

According to sensorimotor theory perceiving is a bodily skill involving exercise of an implicit know-how of the systematic ways that sensations change as a result of potential movements, that is, of sensorimotor contingencies. The theory has been most successfully applied to vision and touch, while perceptual modalities that rely less on overt exploration of the environment have not received as much attention. In addition, most research has focused on philosophically grounding the theory and on psychologically elucidating sensorimotor laws, but the theory's ramifications for neuroscience still remain underexamined. Here we sketch the beginnings of a research program that could address these two outstanding challenges in terms of auditory perception. We review the neuroscience literature on passive listening, which is defined as listening without overt bodily movement, and conclude that sensorimotor theory provides a unique perspective on the consistent finding of motor system activation. In contrast to competing theories, this activation is predicted to be involved not only in the perception of speech-and action-related sounds, but in auditory perception in general. More specifically, we propose that the auditory processing associated with supplementary motor areas forms part of the neural basis of the exercise of sensorimotor know-how: these areas' recognized role in (1) facilitating spontaneous motor responses to sound and (2) supporting flexible engagement of sensorimotor processes to guide auditory experience and enable auditory imagery, can be understood in terms of two key characteristics of sensorimotor interaction, its (1) "alerting capacity" (or "grabbiness") and (2) "corporality" (or "bodiliness"), respectively. We also highlight that there is more to the inside of the body than the brain: there is an opportunity to develop sensorimotor theory into new directions in terms of the still poorly understood active processes of the peripheral auditory system.

In this review, we describe some of the central philosophical issues facing origins-of-life research and provide a targeted history of the developments that have led to the multidisciplinary field of origins-of-life studies. We outline these issues and developments to guide researchers and students from all fields. With respect to philosophy, we provide brief summaries of debates with respect to (1) definitions (or theories) of life, what life is and how research should be conducted in the absence of an accepted theory of life, (2) the distinctions between synthetic, historical, and universal projects in origins-of-life studies, issues with strategies for inferring the origins of life, such as (3) the nature of the first living entities (the "bottom up" approach) and (4) how to infer the nature of the last universal common ancestor (the "top down" approach), and (5) the status of origins of life as a science. Each of these debates influences the others. Although there are clusters of researchers that agree on some answers to these issues, each of these debates is still open. With respect to history, we outline several independent paths that have led to some of the approaches now prevalent in origins-of-life studies. These include one path from early views of life through the scientific revolutions brought about by Linnaeus (von Linn.), Wöhler, Miller, and others. In this approach, new theories, tools, and evidence guide new thoughts about the nature of life and its origin. We also describe another family of paths motivated by a" circularity" approach to life, which is guided by such thinkers as Maturana & Varela, Gánti, Rosen, and others. These views echo ideas developed by Kant and Aristotle, though they do so using modern science in ways that produce exciting avenues of investigation. By exploring the history of these ideas, we can see how many of the issues that currently interest us have been guided by the contexts in which the ideas were developed. The disciplinary backgrounds of each of these scholars has influenced the questions they sought to answer, the experiments they envisioned, and the kinds of data they collected. We conclude by encouraging scientists and scholars in the humanities and social sciences to explore ways in which they can interact to provide a deeper understanding of the conceptual assumptions, structure, and history of origins-of-life research. This may be useful to help frame future research agendas and bring awareness to the multifaceted issues facing this challenging scientific question.

The concept of social interaction is at the core of embodied and enactive approaches to social cognitive processes, yet scientifically it remains poorly understood. Traditionally, cognitive science had relegated all behavior to being the end result of internal neural activity. However, the role of feedback from the interactions between agent and their environment has become increasingly important to understanding behavior. We focus on the role that social interaction plays in the behavioral and neural activity of the individuals taking part in it. Is social interaction merely a source of complex inputs to the individual, or can social interaction increase the individuals' own complexity? Here we provide a proof of concept of the latter possibility by artificially evolving pairs of simulated mobile robots to increase their neural complexity, which consistently gave rise to strategies that take advantage of their capacity for interaction. We found that during social interaction, the neural controllers exhibited dynamics of higher-dimensionality than were possible in social isolation. Moreover, by testing evolved strategies against unresponsive ghost partners, we demonstrated that under some conditions this effect was dependent on mutually responsive co-regulation, rather than on the mere presence of another agent's behavior as such. Our findings provide an illustration of how social interaction can augment the internal degrees of freedom of individuals who are actively engaged in participation.

Tasks encountered in daily living may have instabilities and more dimensions than are sampled by the senses such as when carrying a cup of coffee and only the surface motion and overall momentum are sensed, not the fluid dynamics. Anticipating non-periodic dynamics is difficult
but not impossible because mutual coordination allows for chaotic processes to synchronize to each other and become periodic. A chaotic oscillator with random period and amplitude affords being stabilized onto a periodic trajectory by a weak input if the driver incorporates information
about the oscillator. We studied synchronization with predictable and unpredictable stimuli where the unpredictable stimuli could be non-interactive or interactive. The latter condition required learning to control a chaotic system. We expected better overall performance with the
predictable but more learning and generalization with unpredictable interactive stimuli. Participants practiced an auditory-motor synchronization task by matching their sonified hand movements to sonified tutors: the Non-Interactive Predictable tutor (NI-P) was a sinusoid, the Non-Interactive Unpredictable (NI-U) was a chaotic system, the Interactive Unpredictable (I-U) was the same chaotic system with an added weak input from the participant’s movement. Different pre/post-practice stimuli evaluated generalization. Quick improvement was seen in NIP. Synchronization, dynamic similarity, and causal interaction increased with practice in I-U but not in NI-U. Generalization was seen for few pre-post stimuli in NI-P, none in NI-U, and most stimuli in I-U. Synchronization with novel chaotic dynamics is challenging but mutual interaction enables the behavioral control of such dynamics and the practice of complex motor skills.

It is widely agreed that the standard genetic code must have been preceded by a simpler code that encoded fewer amino acids. How this simpler code could have expanded into the standard genetic code is not well understood because most changes to the code are costly. Taking inspiration from the recently synthesized six-letter code, we propose a novel hypothesis: the initial genetic code consisted of only two letters, G and C, and then expanded the number of available codons via the introduction of an additional pair of letters, A and U. Various lines of evidence, including the relative prebiotic abundance of the earliest assigned amino acids, the balance of their hydrophobicity, and the higher GC content in genome coding regions, indicate that the original two nucleotides were indeed G and C. This process of code expansion probably started with the third base, continued with the second base, and ended up as the standard genetic code when the second pair of letters was introduced into the first base. The proposed process is consistent with the available empirical evidence, and it uniquely avoids the problem of costly code changes by positing instead that the code expanded its capacity via the creation of new codons with extra letters.

Theories of the origin of the genetic code typically appeal to natural selection and/or mutation of hereditable traits to explain its regularities and error robustness, yet the present translation system presupposes high-fidelity replication. Woese’s solution to this bootstrapping problem was to assume that code optimization had played a key role in reducing the effect of errors caused by the early translation system. He further conjectured that initially evolution was dominated by horizontal exchange of cellular components among loosely organized protocells (“progenotes”), rather than by vertical transmission of genes. Here we simulated such communal evolution based on horizontal transfer of code fragments, possibly involving pairs of tRNAs and their cognate aminoacyl tRNA synthetases or a precursor tRNA ribozyme capable of catalysing its own aminoacylation, by using an iterated learning model. This is the first model to confirm Woese’s conjecture that regularity, optimality, and (near) universality could have emerged via horizontal interactions alone.

It is not yet well understood how we become conscious of the presence of other people as being other subjects in their own right. Developmental and phenomenological approaches are converging on a relational hypothesis: my perception of a “you” is primarily constituted by another subject’s attention being directed toward “me.” This is particularly the case when my body is being physically explored in an intentional manner. We set out to characterize the sensorimotor signature of the transition to being aware of the other by re-analyzing time series of embodied interactions between pairs of adults (recorded during a “perceptual crossing” experiment). Measures of turn-taking and movement synchrony were used to quantify social coordination, and transfer entropy was used to quantify direction of influence. We found that the transition leading to one’s conscious perception of the other’s presence was indeed characterized by a significant increase in one’s passive reception of the other’s tactile stimulations. Unexpectedly, one’s clear experience of such passive touch was consistently followed by a switch to active touching of the other, while the other correspondingly became more passive, which suggests that this intersubjective experience was reciprocally co-regulated by both participants.

There exists a venerable tradition of interdisciplinary research into the origins and development of Paleolithic cave painting. In recent years this research has begun to be inflected by rapid advances in measurement techniques that are delivering chronological data with unprecedented accuracy. Patterns are emerging from the accumulating evidence whose precise interpretation demands corresponding advances in theory. It seems that cave painting went through several transitions, beginning with the creation of simple lines, dots and disks, followed by hand stencils, then by outlined figures, and finally by naturalistic figures. So far the most systematic evidence comes from Europe, although there are also indications that this sequence could be a universal pattern. The shamanic hypothesis provides a useful theoretical starting point because of its emphasis on the role of performance and phenomenology in the creative process. However, it still tends to reduce this sequence to mere stylistic and thematic changes that were external products of an already fully formed modern mind. Here I show how key insights from semiotics and material engagement theory can advance this explanatory framework to the extent that we become able to postdict the major transitions in the chronology of Paleolithic cave painting. An intriguing implication is that this is at the same time a chronology of cognitive changes, namely from a performative-phenomenological to a reflective-representational mind.

There is a growing consensus that a fuller understanding of social cognition depends on more systematic studies of real-time social interaction. Such studies require methods that can deal with the complex dynamics taking place at multiple interdependent temporal and spatial scales, spanning sub-personal, personal, and dyadic levels of analysis. We demonstrate the value of adopting an extended multi-scale approach by re-analyzing movement time series generated in a study of embodied dyadic interaction in a minimal virtual reality environment (a perceptual crossing experiment). Reduced movement variability revealed an interdependence between social awareness and social coordination that cannot be accounted for by either subjective or objective factors alone: it picks out interactions in which subjective and objective conditions are convergent (i.e. elevated coordination is perceived as clearly social, and impaired coordination is perceived as socially ambiguous). This finding is consistent with the claim that interpersonal interaction can be partially constitutive of direct social perception. Clustering statistics (Allan Factor) of salient events revealed fractal scaling. Complexity matching defined as the similarity between these scaling laws was significantly more pronounced in pairs of participants as compared to surrogate dyads. This further highlights the multi-scale and distributed character of social interaction and extends previous complexity matching results from dyadic conversation to nonverbal social interaction dynamics. Trials with successful joint interaction were also associated with an increase in local coordination. Consequently, a local coordination pattern emerges on the background of complex dyadic interactions in the PCE task and makes joint successful performance possible.

The role of altered states of consciousness in the production of geometric and figurative art by prehistoric cultures in Africa and Europe has been hotly debated. Helvenston and Bahn have tried to refute the most famous hypothesis, Lewis-Williams' neuropsychological model, by claiming that appropriate visual hallucinations required the ingestion of LSD, psilocybin, or mescaline, while arguing that none of these compounds were available to the cultures in question. We present here mycological arguments that tell another story. A prehistoric worldwide distribution of the mushroom genus Psilocybe, and therefore of psilocybin, is supported by the existence of endemic species in America, Africa, and Europe, the disjunct distribution of sister species, and the possibility of long-distance spore dispersal. It is more difficult to point to instances of actual prehistoric ritual use in Africa and Europe, but there are a growing number of suggestive findings.

Standard crossover operators are often omitted from simple genetic algorithms (GAs) used for optimizing artificial neural networks because of the traditional belief that they generally disrupt the distributed functionality of the evolving solutions. The notion that crossover will be especially disruptive when a genetic representation is used which has a many-to-one mapping between genotype and phenotype has become known as the ‘permutation problem’. In contrast, this paper argues that these problems do not normally
appear in practical use of simple GAs because populations converge quickly and then continue to move through search space in this converged manner until a fitness optimum is found. After convergence all individuals are genetically similar, and moreover, distinct genetic permutations of the same phenotypic solution are unlikely to co-exist in the population. Genetic convergence thus minimizes the possibility for disruption caused by crossover. We have termed this the ‘convergence argument’. This claim is investigated experimentally on standard benchmark problems and the results provide empirical support.

El cibernético mexicano Rosenblueth y sus colegas Wiener y Bigelow argumentaban que el comportamiento dirigido a metas puede ser explicado por la retroalimentación negativa. Esta propuesta revolucionaria implicaba que nuestra experiencia al actuar intencionadamente podía hacerse compatible con una visión del mundo estrictamente científica, en la cual la naturaleza física no sigue ningún propósito. Años después, Wiener fundaría la cibernética bajo el principio de autogobierno, por ejemplo, con el uso de “bucles” de retroalimentación negativa para el control de máquinas. Sin embargo, los seres vivos no sólo son autogobernantes, sino que también, a través del metabolismo, son individuos físicamente autoproductivos. Esto es de importancia para el surgimiento de una nueva ciencia cognitiva que fundamenta el sentido de la existencia en el cuerpo biológico y, por lo tanto, en la mortalidad.

In sociology, there has been a controversy about whether there is any essential difference between a human being and a tool, or if the tool–user relationship can be defined by co-actor symmetry. This issue becomes more complex when we consider examples of AI and robots, and even more so following progress in the development of various bio-machine hybrid technologies, such as robots that include organic parts, human brain implants, and adaptive prosthetics. It is argued that a concept of autonomous agency based on organismic embodiment helps to clarify the situation. On this view, agency consists of an asymmetrical relationship between an organism and its environment, because the continuous metabolic and regulatory activity of the organism gives rise to its own existence, and hence its specific behavioral domain. Accordingly, most (if not all) of current technologies are excluded from the class of autonomous agents. Instead, they are better conceptualized as interfaces that mediate our interactions with the world. This has important implications for design: Rather than trying to help humans to achieve their goals by duplicating their agency in artificial systems, it would be better to empower humans directly by enhancing their existing agency and lived experience with technological interfaces that can be incorporated into their embodiment. This incorporation might be especially facilitated by bio-machine hybrid technology that is designed according the principles of biological autonomy and multi-agent coordination dynamics.

Schizophrenia and high functioning autism-spectrum disorders (ASD) are neurodevelopmental conditions that mainly impair social competence, while general intelligence (IQ) is spared. Both disorders have a strong ancillary role in theoretical research on social cognition. Recently the debate has started to be inflected by embodied and phenomenological approaches, which claim that the standard portrayal of all social understanding as so-called ‘mindreading’, i.e. the attribution of mental states to others in the service of explaining and predicting their behavior, is misguided. Instead it is emphasized that we normally perceive others directly as conscious and goal-directed persons, without requiring any theorizing and/or simulation. This paper evaluates some of the implications of abnormal experiences reported by people with schizophrenia and ASD for the current debate in cognitive science. For these people the practice of explicit mindreading seems to be a compensatory strategy that ultimately fails to compensate for – and may even exacerbate – their impairment of intuitive and interactive social understanding. Phenomenological psychopathology thereby supports the emerging view that ‘mindreading’ is not the principal form of normal social understanding.

The concept of autopoiesis was conceived by Maturana and Varela as providing the necessary and sufficient conditions for distinguishing the living from the non-living (and, by extension, the cognitive from the non-cognitive). More recently however, there has been a growing consensus that their original conception of autopoiesis is necessary but insufficient for this task as it fails to meet a number of constructive, interactive, normative, and historical requirements. We argue that it also fails to satisfy crucial phenomenological requirements that are motivated by the ongoing appropriation of autopoiesis as a key concept in enactive cognitive science. The root of these problems can be traced to the abstract general systems framework in which the ideas were first formulated, as epitomized by Ashby’s cybernetics. While this abstract generality has helped the concept’s popularity in some circles, we insist that a restriction of autopoiesis to a radical embodiment in chemical self-production under far-from-equilibrium conditions is necessary if the concept is to live up to its original intentions.

One of the recurring themes in Čapek's play is the existential question of whether the reductionist materialist worldview-the belief that we can fully explain the world, including ourselves, in terms of nothing but physical processes-can accommodate all that is essential to the human being. The materialist worldview triumphed with the scientific revolution, which in turn laid the foundations for the military-industrial complex. This historical shift is represented in the play by the business-minded young Rossum inheriting the bio-engineering methodology from the mad scientist old Rossum. A key difference between the two is that old Rossum's materialist stance is an ideological commitment, whereas for young Rossum working within a materialist framework is more a matter of convenience: for him it is sufficient for most practical purposes to replicate the machine-like aspects of a person. Where does this leave the soul, or what we today might prefer to call consciousness? The question of whether human nature goes beyond its physical aspects, and whether these subjective aspects can also be artificially replicated, is extremely challenging to address in scientific theory and practice-100 years ago as much as now.

The enactive approach to cognitive science has undergone a biophenomenologically inspired "normative turn" by characterizing an organism's activity as motivated by intrinsic value, where this value is grounded in adaptive self-production under precarious conditions. However, efforts in the field of artificial life to model this enactive conception of life have unwittingly revealed a case of what can be called the hard problem of efficacy (HPE): how could any intrinsic value as such make an effective difference to an organism's behavior, in particular if bodily activity is purely determined by valueless material-organizational factors? First, this theoretical challenge of the HPE is formulated in the context of the enactive account of motivated activity. Then, by critically analyzing Schrödinger's work on the methodological principles that define the scientific world image, it is argued that they can be revised to allow solutions to the HPE. This involves placing a limit on Schrödinger's principle of understandability. The key move is to operationalize this limit with the concept of irruption: an organism's motivations can make a physical difference to its bodily activity, but only indeterminately so, akin to a breakdown of its material-organizational constraints. Irruptions can thereby indirectly facilitate behavior-switching as well as long-term selforganization of adaptive behavior. Finally, it is proposed that the efficacy of motivated activity has its own specific energy cost due to the disordering effect of irruptions, which provides a new perspective on agency and the notion of mental work.

Donald Hebb proposed in his 1949 book The Organization of Behavior that cell assemblies organized by temporallyasymmetric excitation form the basis of cognition. This basic idea has inspired a large body of research in neuroscience, and to a lesser extent in artificial intelligence. The modern manifestation of Hebb's principle is Spike-Timing Dependent Plasticity (STDP), and though we have a large body of experimental work investigating STDP, there is still little understanding of how networks of spiking neurons organize themselves into complex functional circuits, even though some progress has been made with models such as Liquid State Machines. Networks popular in artificial intelligence (e.g. MLPs) and in artificial life (e.g. CTRNNs) tend to eschew Hebb's insight and use error-backpropagation by gradient descent, in the case of AI, or an a-temporal Hebbian learning rule based on the outer product of neural activities, in the case of AL. Both of these approaches have greater interpretability than Spiking Neural Networks (SNNs), but both lack the mechanism that Hebb claimed was fundamental to cognition. This paper proposes to use complex-valued neurons (CVNs) to address this limitation, simultaneously promoting biological interpretation and computational tractability. The CVNs encode the firing rate and spike-time of a spiking neuron in the magnitude and angle, respectively, of a complex number. We also introduce an unsupervised piecewise-linear STDP learning rule compatible with CVNs, which for brevity we call complex-valued STDP (CVSTDP). We demonstrate both learning through error-backpropagation, and the spontaneous formation and dissolution of cell assemblies via the CVSTDP rule.

Social network analysis and agent-based modeling are two approaches used to study biological and artificial multi-agent systems. However, so far there is little work integrating these two approaches. Here we present a first step toward integration. We developed a novel approach that allows the creation of a social network on the basis of measures of interactions in an agent-based model for purposes of social network analysis. We illustrate this approach by applying it to a minimalist case study in swarm robotics loosely inspired by ant foraging behavior. For simplicity, we measured a network's inter-agent connection weights as the total number of interactions between mobile agents. This measure allowed us to construct weighted directed networks from the simulation results. We then applied standard methods from social network analysis, specifically focusing on node centralities, to find out which are the most influential nodes in the network. This revealed that task allocation emerges and induces two classes of agents, namely foragers and loafers, and that their relative frequency depends on food availability. This finding is consistent with the behavioral analysis, thereby showing the compatibility of these two approaches.

It has recently been demonstrated that a Hopfield neural network that learns its own attractor configurations, for instance by repeatedly resetting the network to an arbitrary state and applying Hebbian learning after convergence, is able to form an associative memory of its attractors and thereby facilitate future convergences on better attractors. This process of structural self-optimization has so far only been demonstrated on relatively small artificial neural networks with random or highly regular and constrained topologies, and it remains an open question to what extent it can be generalized to more biologically realistic topologies. In this work, we therefore test this process by running it on the connectome of the widely studied nematode worm, C. elegans, the only living being whose neural system has been mapped in its entirety. Our results demonstrate, for the first time, that the self-optimization process can be generalized to bigger and biologically plausible networks. We conclude by speculating that the reset-convergence mechanism could find a biological equivalent in the sleep-wake cycle in C. elegans.

Referential communication is a "representation-hungry" behavior , and the bee waggle dance is a classical example of ref-erential communication in nature. We used an evolutionary robotics approach to create a simulation model of a minimalist example of this situation. Two structurally identical agents engage in embodied interaction such that one of them can find a distant target in 2D space that only the other could perceive. This is a challenging task: during their interaction the agents must disambiguate translational and communicative movements, allocate distinct behavioral roles (sender versus receiver), and switch behaviors from communicative to target seeking behavior. We found an evolutionary convention with compositionality akin to the waggle dance, correlating duration and angle of interaction with distance and angle to target, respectively. We propose that this behavior is more appropriately described as interactive mindshaping, rather than as the transfer of informational content.

Homeostatic systems tend to have a preferred state that it can be referred as a healthy state in traditionally-known systems such as the cardiovascular system. Any deviation from this state has been linked to disease. Different types of variables interact within homeostatic systems. Recently it has been described 2; “regulated” and “regulating” variables both of them with specific statistics that correlate to their function in maintaining homeostasis. We stated in this study that perception and mastery of a task with a sensory substitution system can be viewed and studied in a similar manner as traditionally-known homeostatic systems. We propose and exemplified with 2 cases of study that the state of mastery, from a time series perspective, share similarities between the statistics of their variables with healthy states in traditionally-known homeostatic systems, and that variations from that state of mastery share similarities with disease processes in traditionally-known homeostatic systems.

Artificial life has been developing a behavior-based perspective on the origins of life, which emphasizes the adaptive potential of agent-environment interaction even at that initial stage. So far this perspective has been closely aligned to metabolism-first theories, while most researchers who study life's origins tend to assign an essential role to RNA. An outstanding challenge is to show that a behavior-based perspective can also address open questions related to the genetic system. Accordingly, we have recently applied this perspective to one of science's most fascinating mysteries: the origins of the standard genetic code. We modeled horizontal transfer of cellular components in a population of protocells using an iterated learning approach and found that it can account for the emergence of several key properties of the standard code. Here we further investigated the diachronic emergence of artificial codes and discovered that the model's most frequent sequence of amino acid assignments overlaps significantly with the predictions in the literature. Our explorations of the factors that favor early incorporation into an emerging artificial code revealed two aspects: an amino acid's relative probability of horizontal transfer, and its relative ease of discriminability in chemical space.

Hopfield networks can exhibit many different attractors of which most are local optima. It has been demonstrated that combining states randomization and Hebbian learning enlarges the basin of attraction of globally optimal attractors. The procedure is called self-modeling and it has been applied in symmetric Hopfield networks with discrete states and without self-recurrent connections. We are interested in knowing which topological constraints can be relaxed. So, the self-modeling process is tested in asymmetric Hopfield networks with continuous states and self-recurrent connections. The best results are obtained in networks with modular structure.

Referential communication is a complex form of social interaction whereby agents manage to coordinate behavior with respect to features that are not immediately present during the interaction. A famous example from nature is the bee waggle dance. The authors used an minimal cognitive approach to create a model of referential communication that is sufficiently minimal to permit a full dynamical analysis, and yet still complex enough so that the results provide a useful perspective onto the processes that could be involved in natural referential communication. The task is for two embodied agents to interact in a “hive” area such that one of the agents (the receiver) is able to move to a specific “target”, the location of which is only available to the other agent (the sender). The task implicitly requires adopting the right role (sender vs. receiver), disambiguating between translational and communicative motion, and switching from communicative to target seeking behavior. Similar to the waggle dance, the best solution involved a correlation between duration of contact and distance to be traveled. Dynamical analysis revealed that this behavior cannot be attributed to the sender in isolation.

Enactivists are searching for the conditions of genuine intersubjectivity. Theory of mind approaches to social cognition have come a long way from folk psychological theorizing by paying more attention to neuroscientific evidence and phenomenological insights. This has led to hybrid accounts that incorporate automatic processing and allow an instrumental role for perception and interaction. However, two foundational assumptions remain unquestioned. First, the cognitive unconscious: explanations assume there is a privileged domain of subpersonal mechanisms that operate in terms of representational personal-level concepts (belief, desire, inference, pretense, etc.), albeit unconsciously. Second, methodological individualism: explanations of social capacities are limited to mechanisms contained within the individual. The enactive approach breaks free from these representationalist-internalist constraints by integrating personal-level phenomenology with multi-scale dynamics occurring within and between subjects. This formal and empirical research on social interaction supports the possibility of genuine intersubjectivity: we can directly participate in the unfolding of each other’s experience.

Computationalism aspires to provide a comprehensive theory of life and mind. It fails in this task because it lacks the conceptual tools to address the problem of meaning. I argue that a meaningful perspective is enacted by an individual with a potential that is intrinsic to biological existence: death. Life matters to such an individual because it must constantly create the conditions of its own existence, which is unique and irreplaceable. For that individual to actively adapt, rather than to passively disintegrate, expresses a value inherent in its way of life, which is the ultimate source of more refined forms of normativity. This response to the problem of meaning will not satisfy those searching for a functionalist or logical solution, but on this view such a solution will not be forthcoming. As an intuition pump for this alternative perspective I introduce two ancient foreign worldviews that assign a constitutive role to death. Then I trace the emergence of a similar conception of mortality from the cybernetics era to the ongoing development of enactive cognitive science. Finally, I analyze why orthodox computationalism has failed to grasp the role of mortality in this constitutive way.

Ideas related to the creation of life have a long history in the Old World, reaching back to the times of classical antiquity, and are expressed in a diverse range of intersecting fields jointly known as artificial life today. It has been argued that the modern sciences of the artificial could learn something from these classical myths. What is less well known is that ancient Mesoamerican cultures also possessed a rich corpus of
myths related to what we would now refer to as artificial life. In other words, although this is the first time that an ALife conference takes place in Mesoamerica, in a sense the central concept of the field, i.e. the creation of life via artificial means, has already been around the region for centuries if not for over a millennium. In the following we will focus on the specific case of the Maya, from whom several myths related to this concept have survived.

Cooperation in scale-free networks has proven to be very robust against removal of randomly selected nodes (error) but highly sensitive to removal of the most connected nodes (attack). In this paper we analyze two comparable types of node removal in which the removal selection is based on tournaments where the fittest (raids) or the least fit (battles) nodes are chosen. We associate the two removals to two types of Maya warfare offences during the Classic period. During this period of at least 500 years, political leaders were able to sustain social order in spite of attack-like offences to their social networks. We present a computational model with a population fluctuation mechanism that operates under an evolutionary game theoretic approach using the Prisoner's Dilemma as a metaphor of cooperation. We find that paradoxically battles are able to uphold cooperation under moderate levels of raids, although raids do have a strong impact on the network structure. We infer that cooperation does not depend as much on the structure as it does on the underlying mechanism that allows the network to readjust. We relate the results to the Maya Classic period, concluding that Mayan warfare by itself cannot entirely explain the Maya political collapse without appealing to other factors that increased the pressures against cooperation.

One problem in the origins of life is how parasitic side-reactions can be mitigated. It is known that spatial self-organisation can help with this, making autocatalytic chemical systems more robust to invasion by parasitic species. In previous work we have shown that in such scenarios parasitic reactions can actually be beneficial. Here we demonstrate for the first time a system in which the presence of a parasitic autocatalytic cycle is not only beneficial but actually necessary for the persistence of its host. This occurs due to the effect the parasite has on the spatial organisation of the system; the host-parasite system is more stable than the host alone, despite the fact that the parasite’s direct effect on its host is purely negative. We briefly discuss the implications for the origins of life.

In the origin of life community there has been a dispute about whether metabolism or replication came first. Yet both of these approaches are in implicit agreement that the first forms of life were basically passive. That shared assumption has begun to be challenged by a new generation of metabolism-first approaches, emphasizing that movement and adaptive behavior could have played an important role right from the start. After introducing recent research on this behavior-based approach to the origin of life, I offer a preliminary assessment of what this new approach implies for the origins of the genetic system.

We argue that the signicance of the spatial boundary in autopoiesis has been overstated. It has the important task of distinguishing a living system as a unity in space but should not be seen as playing the additional role of delimiting the processes that make up the autopoietic system. We demonstrate the relevance of this to a current debate about the compatibility of the extended mind hypothesis with the enactive approach and show that a radically extended interpretation of autopoiesis was intended in one of the original works on the subject. Additionally we argue that the denitions of basic terms in the autopoietic literature can and should be made more precise, and we make some progress towards such a goal.

This paper supports the view that the ongoing shift from orthodox to embodied-embedded cognitive science has been significantly influenced by the experimental results generated by AI research. Recently, there has also been a noticeable shift toward enactivism, a paradigm which radicalizes the embodied-embedded approach by placing autonomous agency and lived subjectivity at the heart of cognitive science. Some first steps toward a clarification of the relationship of AI to this further shift are outlined. It is concluded that the success of enactivism in establishing itself as a mainstream cognitive science research program will depend less on progress made in AI research and more on the development of a phenomenological pragmatics.

The enactive approach to perception is generating an extensive amount of interest and debate in the cognitive sciences. One particularly contentious issue has been how best to characterize the perceptual experiences reported by subjects who have mastered the skillful use of a perceptual supplementation (PS) device. This paper argues that this issue cannot be resolved with the use of third-person methodologies alone, but that it requires the development of a phenomenological pragmatics. In particular, it is necessary that the experimenters become skillful in the use of PS devices themselves. The ‘Enactive Torch’ is proposed as an experimental platform which is cheap, non-intrusive and easy to replicate, so as to enable researchers to corroborate reported experiences with their own phenomenology more easily.

In the field of artificial life there is no agreement on what defines ‘autonomy’. This makes it difficult to measure progress made towards understanding as well as engineering autonomous systems. Here, we review the diversity of approaches and categorize them by introducing a conceptual distinction between behavioral and constitutive autonomy. Differences in the autonomy of artificial and biological agents tend to be marginalized for the former and treated as absolute for the latter. We argue that with this distinction the apparent opposition can be resolved.

There is an abundance of spirals, zigzag patterns, crosses, grids, and other visual forms. Many of these motifs are repeated across independent cultural contexts, yet they do not appear to be images of natural phenomena. One possibility is that they symbolise some of the essential visual features of altered states of consciousness, which can be induced by shamanic trance.

The enactive approach is a growing movement in cognitive science that replaces the classical computer metaphor of the mind with an emphasis on biological embodiment and social interaction as the sources of our goals and concerns. Mind is viewed as an activity of making sense in embodied interaction with our world. However, if mind is essentially a concrete activity of sense-making, then how do we account for the more typically human forms of cognition, including those involving the abstract and the patently nonsensical? To address this crucial challenge this collection brings together new contributions from the sciences of the mind that draw on a wide variety of disciplines, including psychopathology, phenomenology, primatology, gender studies, quantum physics, immune biology, anthropology, philosophy of mind, and linguistics. This book is required reading for anyone who is interested in how the latest scientific insights are changing how we think about the human mind and its limits.

Deacon develops a minimal model of a nonparasitic virus to explore how nucleotide sequences came to be characterized by a code-like informational codependence at the origin of life. The model serves to problematize the concept of biological normativity because it highlights two common yet typically implicit assumptions: (1) that life could consist as an inert form, were it not for extrinsic sources of physical instability, and (2) that life could have originated as a singular self-contained individual. I propose that the origin of life, the genetic code, and biological normativity more generally, lead us to reject this passive individualism.

We applaud Tsuboi et al. for assembling the most extensive brain-body-mass dataset to date and making it publicly available. However, care must be taken when comparing static allometry between lineages exhibiting indeterminate versus determinate growth. It makes little sense to compare the continuous brain-body growth trajectories of adult fish, reptiles, and amphibians with the brain-body weight variability of adult birds and mammals whose growth has ceased. Instead, we agree with Deacon 2: 260 that "comparing ontogenetic curves is ultimately the only way to provide some assurance that we are not comparing apples and oranges". We therefore doubt that smaller slopes of static allometry in adult birds and mammals, which reflect weight variability across individuals whose brains have ceased growing, can help to explain their encephalization.

El mejor antídoto para la manipulación por parte de intereses creados es una combinación de conocer los hechos y el pensamiento crítico. Sin embargo, en lugar de usar la educación como la principal estrategia de defensa contra la interferencia en el proceso democrático, los gobiernos de todo el mundo han estado ocupados desmantelando el sistema educativo. La educación superior es siempre el primer sector al cual se reduce su ya limitado presupuesto, y el objetivo declarado de muchas universidades ha dejado de ser el de capacitar a las personas para el pensamiento crítico. El objetivo principal se ha convertido en la producción de trabajadores que sean útiles para que las empresas obtengan beneficios económicos. Se están cerrando departamentos en las universidades que no encajan fácilmente dentro de este esquema. Los campos más afectados por estos cierres y cortes son precisamente los que estarían en la mejor posición para inocular a los ciudadanos contra la manipulación: las ciencias sociales, las humanidades y, en particular, la filosofía.

There is growing dissatisfaction with the traditional approach to the evolution of complex societies, which treated it principally as a sequence of transformations toward political centralization driven by the construction of increasingly vertical hierarchies by a powerful elite. In Mesoamerica the evidence is more consistent with a variety of alternative pathways to social complexity, and these are fruitfully approached from theoretical perspectives based on social heterarchy (Crumley 2003), collective action (Fargher et al. 2011), and, so I will suggest, ritual anti-structure (Turner 1969).

When administered in controlled settings, they have been reported to induce a wide variety of long-lasting positive psychological changes. However, the mechanisms by which psychedelics impart these long-lasting benefits remain poorly understood. Here we highlight one possibility that has remained underexplored: a beneficial interaction with the self-optimizing functions of sleep.

The study and simulation of adaptive behavior in natural and artificial systems have always involved the convergence of several disciplines, interests, and methods. Since its inception, the pages of this journal have reflected a cross-fertilization between the sciences of the artificial, the sciences of living systems, and the sciences of the mind. As a result, Adaptive Behavior has been, and continues to be, a forum for innovative, creative , yet rigorous, work on complex adaptive systems, robotic and computational investigations of behavior and cognition, as well as novel theoretical developments and applications.

Open peer commentary on the article “Interactivity and Enaction in Human Cognition” by Matthew Isaac Harvey, Rasmus Gahrn Andersen & Sune Vork Steffensen. Upshot: Enaction is a diverse research program and some of its texts can be interpreted in terms of a critical contrast to interactivity. Yet much of the former has already started to move in a direction favored by the latter: toward systematic studies of how human activity is shaped by social, cultural, and technological influences. Interactivity could therefore help enaction to provide a better account of such highly mediated and augmented forms of sense-making.

In this short introduction I situate their contributions in what I see as important aspects of the bigger picture that is motivating and inspiring them as well as the rest of this young community. In particular, I sketch some of the social issues that go beyond mere academic debate, including how the methods and assumptions that inform orthodox cognitive science are intrinsically related to the critical state of affairs in our world today. I conclude with some personal recollections in order to give an idea of the context in which their ideas, and mine as well, came to fruition.

John Stewart and I wrote a response to Maturana’s commentary on our 2010 paper, in which we clarify our position and offer some further reflections on the similarities and differences between Maturana’s biology of cognition and the enactive approach to cognitive science. We agree that Maturana’s work is an improvement over Ashby’s approach to biological function, but we also suggest that the enactive approach is in important respects an improvement over the biology of cognition.

The ever-increasing precision of brain measurement brings with it a demand for more reliable and fine-grained measures of conscious experience. However, introspection has long been assumed to be too limited and fallible. This skepticism is primarily based on a series of classic psychological experiments, which suggested that more is seen than can be retrospectively reported (Sperling, 1960), and that we can be easily fooled into retrospectively describing intentional choices that we have never made (Johansson, Hall, Silkström, & Olsson, 2005; Nisbett & Wilson, 1977). However, the work by Petitmengin, Remillieux, Cahour, and Carter-Thomas (2013) could resolve this dilemma. They showed that subjects can be interactively guided to become better aware of their past experience, thereby overturning the “choice blindness” results of Johansson et al. (2005). Although some more fine-tuning of the experimental protocol is needed, interactively guided introspection may well become the most reliable and exhaustive measure of consciousness.

Franchi argues that Ashby’s homeostat can be usefully understood as a thought experiment to explore the theory that life is fundamentally heteronomous. While I share Franchi’s interpretation, I disagree that this theory of life is a promising alternative that is at odds with most of the Western philosophical tradition. On the contrary, heteronomy lies at the very core of computationalism, and this is precisely what explains its persistent failure to construct life-like agents.

Sato and colleagues make use of an innovative method that combines robotics modeling and psychological experimentation to investigate how tool use affects our living and lived embodiment. I situate their approach in a general shift from robotics to human-computer interface studies in enactive cognitive science, and speculate about the necessary conditions for the bodily incorporation of tools.

Seth extends predictive processing with counterfactuals: Encoded probabilities of what would occur given a repertoire of possible (but unexecuted) actions. He thereby provides a neat mathematical formulation of the sensorimotor account of perceptual presence, i.e., of the fact that we perceive a whole object while being limited to seeing it from a perspective. Synesthetic concurrents are explained in terms of impoverished counterfactuals. I argue that this explanation misses its target, because it only accounts for a lack of objecthood. Enactive theory is better suited to explain concurrents’ lack of subjectivity veridicality. The world itself shapes experience only during veridical perception.

This article was originally motivated by a couple of critical commentaries about my work (Helvenston 2014, and above). However, I quickly came to realise that, to be able to adequately respond to the specific concerns that were raised, I would have to present some general considerations. It is only with this context in place that it becomes clear why I think that these details are worth arguing over in the first place. Thus, before anything else, the overarching question is: when it comes to the formidable task of understanding human pre-History, why should we care about altered states of consciousness?

This MIT Press volume edited by Durt et al. (2017) is concerned with investigating how people bring about a shared sociocultural world through participatory and broader collective sense-making processes, while at the same time highlighting how the participants in these social processes are themselves transformed by the world they help to bring forth. The key insight that runs through this interdisciplinary collection of 20 chapters is the irreducible nature of this interdependence between individual and collective processes: participation in, and hence the cultural reproduction of, patterned practices of the social world is only realizable via a thorough transformation of individual embodied minds.

Fuchs (2018) book starts with a wake-up call. We are facing social and ecological crises that threaten the flourishing of future generations. Ideally, therefore, the sciences of the mind should help us to better understand on what basis a person can take responsible action, and thereby contribute to empowering people in their capacity to make a difference. Yet mainstream human neuroscience confronts us with the hypothesis that our self, free will, consciousness, and hence also our conscience, are nothing but internal fictions fabricated by patterns of nervous activity. Fuchs' book is a valuable reminder of the high price of this sort of reductionism, which realizes the ideal of naturalizing the mind at the cost of leaving no theoretical room for people to genuinely make a difference for others in the world. It is a scientific worldview that implicitly legitimizes todays widespread sense of isolation and apathy. A key motivation for Fuchs is to shore up resistance against this encroachment upon our personal lifeworld, but he wisely refrains from overplaying this appeal to our conscience. The book's main contribution lies in demonstrating that doing justice to the complexities and ambiguities of human existence actually leads to a more mature cognitive science and a more coherent philosophy of mind.

> Context • There is a growing recognition in consciousness science of the need for rigorous methods for obtaining accurate and detailed phenomenological reports of lived experience, i.e., descriptions of experience provided by the subject living them in the “first-person.” > Problem • At the moment although introspection and debriefing interviews are sometimes used to guide the design of scientific studies of the mind, explicit description and evaluation of these methods and their results rarely appear in formal scientific discourse. > Method • The recent publication of an edited book of papers dedicated to the exploration of first-and second-person methods, Ten Years of Viewing from Within: The Legacy of Francisco Varela, serves as a starting point for a discussion of how these methods could be integrated into the growing discipline of consciousness science. We complement a brief review of the book with a critical analysis of the major pilot studies in Varela’s neurophenomenology, a research program that was explicitly devised to integrate disciplined experiential methods with the latest advances in neuroscience. > Results • The book is a valuable resource for those who are interested in impressive recent advances in first- and second person methods, as applied to the phenomenology of lived experience. However, our review of the neurophenomenology literature concludes that there is as yet no convincing example of these specialized techniques being used in combination with standard behavioral and neuroscientific approaches in consciousness science to produce results that could not have also been achieved by simpler methods of introspective reporting. > Implications • The end of behaviorism and the acceptance of verbal reports of conscious experience have already enabled the beginning of a science of consciousness. It can only be of benefit if new first- and second-person methods become well-known across disciplines. > Constructivist content • Constructivism has long been interested in the role of the observer in the constitution of our sense of reality, so these developments in the science of consciousness may open new avenues of constructivist research. More specifically, one of the ways in which the insights from first- and second person methods are being validated is by recursively applying the methods to themselves; a practical application of an epistemological move that will be familiar to constructivists from the second-order cybernetics tradition.

Critics of the paradigm of enaction have long argued that enactive principles will be unable to account for the traditional domain of orthodox cognitive science, namely “higher-level” cognition and specifically human cognition. Moreover, even many of the paradigm’s “lower-level” insights into embodiment and situatedness appear to be amenable to a functionalist reinterpretation. In this review, I show on the basis of the recently published collection of papers, Enaction, that the paradigm of enaction has (a) a unique foundation in the notion of sense-making that places fundamental limits on the scope of functionalist appropriation; (b) a unique perspective on higher-level cognition that sets important new research directions without the need for the concept of mental representation; (c) a new concept of specifically human cognition in terms of second-order sense-making; and (d) a rich variety of approaches to explain the evolutionary, historical, and developmental origins of this sophisticated human ability. I also indicate how studies of the role of embodiment for abstract human cognition can strengthen their position by reconceiving their notion of embodiment in enactive terms.

Increasing numbers of philosophers of mind and cognitive scientists are jumping on the embodied cognition bandwagon. Accordingly, mind is no longer viewed as locked away in some Platonic realm of pure logic, as the computational theory of mind has traditionally proposed. Instead, mind has become identified with purposeful activity in the world, an activity that is realized by the body, extended by usage of tools, and scaffolded by a sociocultural environment.

I review The Feeling Body: Affective Science Meets the Enactive Mind by Giovanna Colombetti (Cambridge, Massachusetts: MIT Press, 2014, 288 pages, $40.00 hardcover). In this book Colombetti draws on the enactive theory of organismic embodiment and its key concept of sense-making in order to critically evaluate various aspects of mainstream affective science, including basic emotions and alternative constructionist approaches, as well as the cognitivist approach to emotion and appraisal theory. She defends and develops a dynamical systems approach to emotions and emphasizes the need for including more first-person methods of consciousness science in mainstream affective neuroscience. These are valuable contributions to affective science, and they also advance enactive theory. Colombetti’s proposal goes further than standard neurophenomenology in that she appeals to the bodily basis of feeling, thereby requiring a new sort of neuro-physio-phenomenology. Even more radically, she allows that all living beings are essentially affective beings, even those without a nervous system, and that emotional forms could be co-constituted by more than one person.

Pessoa’s The Cognitive-Emotional Brain (2013) is an integrative approach to neuroscience that complements other developments in cognitive science, especially enactivism. Both accept complexity as essential to mind; both tightly integrate perception, cognition, and emotion, which enactivism unifies in its foundational concept of sense-making; and both emphasize that the spatial extension of mental processes is not reducible to specific brain regions and neuroanatomical connectivity. An enactive neuroscience is emerging.

The life-mind continuity thesis holds that mind is prefigured in life and that mind belongs to life. Its biggest challenge is the problem of scalability: how can the same explanatory framework that accounts for basic phenomena of life and mind be extended to incorporate the highest reaches of human cognition? So far there has been little systematic response to this „cognitive gap‟. The main argument of this thesis is that the problem appears insurmountable because of the prevalent focus on the individual agent alone, and that it can start to be addressed by an appreciation of the constitutive role of sociality for mind and behavior. This argument is developed in a theoretical, experimental, and phenomenological manner. In terms of theory, the enactive paradigm of cognitive science is developed in a novel direction by highlighting the specific manner in which the dynamics of the interaction process opens up new behavioral domains. This provides the motivation for using an evolutionary robotics methodology to synthesize a set of minimalist simulation models that are based on experiments in social psychology. A detailed dynamical analysis of these models supports the enactive approach; the behavior of the agents is not an individual achievement alone but rather co-determined by their mutual interaction and organized effectively by this multi-agent interaction process. Some phenomenological observations complement these results by indicating that the detached perceptual attitude that is characteristic of adult human perception is essentially an intersubjective and socially mediated ability. Finally, the systemic and phenomenological insights are combined to provide the beginnings of a novel perspective on the origins of cumulative cultural development that gives further support to the main argument of this thesis. It is concluded that the life-mind continuity thesis is a viable working hypothesis even when accounting for specifically human abilities, and that an appreciation of the constitutive role of sociality for life and mind confirms it to be a serious contender for a unified theory of cognitive science.

El presente texto considera cuestiones en torno a la continuidad y la discontinuidad entre la vida y la mente. Inicia examinando dichas cuestiones desde la perspectiva del principio de energía libre (PEL). El PEL se ha vuelto considerablemente influyente tanto en la neurociencia como en la ciencia cognitiva. Postula que los organismos actúan para conservarse a sí mismos en sus estados biológicos y cognitivos esperados, y que lo logran al minimizar su energía libre, dado que el promedio de energía libre a largo plazo es entropía. El texto, por lo tanto, argumenta que no existe una sola interpretación del PEL para pensar la relación entre la vida y la mente. Algunas formulaciones del PEL dan cuenta de lo que llamamos una perspectiva de independencia entre la vida y la mente. Una perspectiva de independencia es la perspectiva cognitivista del PEL, misma que depende del procesamiento de información con contenido semántico, y por ende, restringe el rango de sistemas capaces de exhibir mentalidad. Otras perspectivas de independencia ejemplifican lo que llamamos la demasiado generosa perspectiva no-cognitivista del PEL, que parecen ir en dirección opuesta: sugieren que la mentalidad se encuentra casi en cualquier lugar. El texto continúa argumentando que el PEL no-cognitivista y sus implicaciones para pensar la relación entre la vida y la mente puede ser útilmente delimitado por las recientes aproximaciones enactivas a la ciencia cognitiva. Concluimos que la versión más contundente de la relación vida-mente las considera fuertemente continuas, y esta continuidad se basa en conceptos particulares de vida (autopoiesis y adaptabilidad) y mente (básica y no-semántica).

El computacionalismo aspira a ofrecer una teoría unificadora de la vida y la mente. Fracasa en esta tarea debido a que carece de las herramientas conceptuales para abordar el problema del significado. Argumento que una postura significativa es enactuada por un individuo con el potencial intrínseco a toda existencia biológica: la muerte. Para este individuo la vida importa a fin de adaptarse activamente, en lugar de desintegrarse pasivamente. Introduciré dos cosmovisiones antiguas y extranjeras que asignan a la muerte un rol constitutivo. Posteriormente, trazaré la emergencia de una concepción similar de mortalidad, derivada desde la era cibernética al desarrollo actual enfoque enactivo de la ciencia cognitiva. Finalmente, se analiza por qué el computacionalismo ortodoxo ha fracasado en atisbar de esta manera constitutiva el papel de la mortalidad.

De acuerdo al enfoque enactivo de las ciencias cognitivas, la percepción es esencialmente una forma habilidosa de abordar al mundo. Aprender como abordarlo mediante interfaces humano-computadora, (IHC) puede por lo tanto ser visto como una forma de desarrollar un nuevo modo de experiencia. De forma similar, se ha teorizado que la percepción social está constituida por una forma hábil de abordarse entre personas, lo que implica que es posible investigar los orígenes y desarrollo de la conciencia social utilizando IHCs multiusuario. En el presente artículo analizamos los cambios objetivos y subjetivos ensayo-a-ensayo en la socialización que tuvo lugar durante un experimento de cruce perceptual, en el cual, la interacción corporeizada entre pares de adultos fue mediada por una IHC háptica minimalista. Dado que el estudio requirió que los participantes reaprendieran implícitamente cómo abordarse entre sí para percibir las presencias el uno del otro, hipotetizamos que habría indicaciones de que los estadios iniciales de la conciencia social eran de hecho recapitulados. Resultados preliminares revelan que, pese a una carencia de retroalimentación explicita sobre el desempeño de la tarea, había una tendencia de la conciencia social a incrementar a través del tiempo. Discutimos los desafíos metodológicos implicados en evaluar si esta tendencia fue causada por distintos estadios del desarrollo de conducta objetiva y experiencia subjetiva.

W artykule tym opowiadam się za zunifikowaną kognitywistyką, przyjmując dla swej argumentacji niecodzienny punkt wyjścia: stanowisko określane czasem jako " teza o kontinuum życia-umysłu ". Zamiast więc traktować jako pewnik powszechnie akcep-towane założenia początkowe, a następnie proponować odpowiedzi na pewne do-brze określone pytania, muszę najpierw dowieść, że koncepcja kontinuum życia-u-mysłu może w ogóle stanowić właściwy punkt startowy. Zacznę zatem od oceny poję-ciowych narzędzi, odpowiednich do budowania teorii umysłu na tej podstawie. Czer-piąc spostrzeżenia z wielu różnych dziedzin – szczególnie z połączenia egzystencja-listycznej fenomenologii ze skoncentrowaną na organizmie biologią – dowodzę, że można pojmować umysł jako zakorzeniony w życiu, ale tylko wtedy, gdy równocze-śnie zgodzimy się, że interakcja społeczna gra konstytutywną rolę w naszych zdolno-ściach poznawczych.

The Santuario de Tlaloc on the summit of Cerro del Patlachique was likely the site of rainfall petitioning rituals during Teotihuacano times. Although four different archaeological projects have visited the site, each of them calls it by a different name—Santuario de Tlaloc, Cerro Patlachique, TC-100, and Cerro Xoconoch—complicating a cohesive perspective on the shrine. In this research note, we recount the complete history of research at the site while providing a summary of the interpretation of the site as one devoted to water worship. We then describe a newly discovered carved stone monument, presenting it within its artistic, archaeological, and historical context. The monument is from the Early Classic and shows the storm god wearing a year-sign headdress. Due to the specific headdress, and the monument’s central placement on the main platform and next to its reservoir, we propose that the monument was a primus inter pares of Storm Gods or tlaltoques in spiritual pilgrimage to the Sanctuary—paralleling the physical pilgrimage of Teotihuacan’s political leaders to the same structures.
