I am a Fellow and Assistant Professor at the Aarhus Institute of Advanced Studies and a Research Associate both at the Research Unit of Robophilosophy and Integrative Social Robotics and at the Center of Functionally Integrative Neuroscience at Aarhus University, Denmark.

Previously, I was an FWO Postdoctoral Fellow at the Centre for Philosophical Psychology at the University of Antwerp (Belgium), a visiting scholar at the Department of Philosophy at New York University, and a DFF-Mobilex Postdoctoral Fellow at the Department of Philosophy and at the Cognitive Neuroscience Research Unit at Aarhus University.

My PhD is from the School of Philosophy, Psychology and Language Sciences at the University of Edinburgh. My supervisors were Jesper Kallestrup, Andy Clark, and Mark Sprevak. My external reviewer was Tim Bayne.

My main research interests lie in the intersection of philosophy of mind, philosophy of science, cognitive science and artificial intelligence research. I focus on conscious experiences (both 'online' perceptual and 'offline' spontaneous varieties like creative idea generation, mind-wandering and dreaming): how brain processes might bring them about, and how they might be implemented in machines. I am also interested in how explanations work in inter-theoretical scientific contexts and in the case of algorithmic decision-making.

I have degrees, and research and teaching experience in engineering physics, philosophy of science, philosophy of mind, and cognitive science.

Flat Mechanisms: A Reductionist Approach to Levels in Mechanistic Explanations

Some ascribe ontological weight to these levels, whereas others claim that characterising a higher-level entity and the corresponding lower-level mechanism are only different descriptions of the same thing. The goal of this paper is to develop a consistent metaphysical picture that can underly the latter position. According to this flat view, mechanistic wholes are modules that together with their parts are embedded in the same network of interacting units. The flat view preserves the original virtues of the mechanistic approach and is able to avoid the problems associated with the multi-level view.

Hallucinations as intensified forms of mind-wandering

Starting from the observation that hallucinations are associated with hyperactive sensory areas underlying the content of hallucinatory experiences and a confusion with regard to the reality of the source of these experiences, the paper first reviews the different factors that might contribute to the impairment of reality monitoring. The paper then focuses on the sensory characteristics determining the vividness of an experience, reviews their relationship to the sensory hyperactivity observed in hallucinations, and investigates under what circumstances they can drive reality judgements. Finally, based on these considerations, the paper presents its main proposal according to which hallucinations are intensified forms of mind-wandering that are amplified along their sensory characteristics, and sketches a possible model of what factors might determine if an internally and involuntarily generated perceptual representation is experienced as a hallucination or as an instance of mind-wandering.

Dreaming, Mind-Wandering, and Hypnotic Dreams

This account inspired theoretical models of other altered states of consciousness-including hypnosis-claiming that studying REM dreaming can advance our understanding of these phenomena as well. However, recent developments showed that hypnosis is not a sleep like stage, and that the REM-centric attitude toward dreaming is mistaken. At the same time, the advancement of the neuro-cognitive theory claiming that dreaming and mind-wandering are on a continuum both underlain by default-mode network activity called many aspects of the AIM theory into question. Our aim in this paper is to show that certain hypnotic states-hypnotic dreams (experiences that subjects have in a hypnotic state as a result of an explicit suggestion to have a dream)-can, nevertheless, be highly relevant for the neuro-cognitive theory, and that their comparison with dreaming and mind-wandering has the potential to advance the field in unexpected ways.

Perceptual representations and the vividness of stimulus-triggered and stimulus-independent experiences

Accumulating evidence suggests that in all these cases the activity of posterior brain regions provide the contents of experiences. This paper is interested in moving one step further by exploring specific links between the vividness of experiences, which is a characteristic feature of consciousness regardless of its actual content, and certain properties of the content-specific neural activity patterns. Investigating the mechanisms that underlie mental imagery and its relation to working memory, and the processes responsible for mind wandering and its similarities to dreaming form two clusters of research that are in the forefront of recent scientific study of mental phenomena, yet cross-talk between these two clusters have been surprisingly sparse. Here our aim is to foster such a cross-talk by articulating a hypothesis about the fine-grained phenomenological structure determining subjective vividness and its possible neural basis that allows us to shed new light on these mental phenomena by bringing them under a common framework.

A Dynamical Systems Approach to Causation

Causal claims assert connections between two sets of physicals states-their truth depends on whether the two sets in question are genuinely connected by time evolution such that physical states from one set evolve with time into the states of the other set. We demonstrate the virtues of our approach by showing how it is able to account for typical causes, causally relevant factors, being 'the' cause, and cases of overdetermination and causation by absences.

Multidimensional degrees of consciousness: Qualities of experiences during wakeful perception, working memory tasks, mental imagery, mind wandering and dreaming

by Georgina Németh and Peter Fazekas

Overgaard, M., Mogensen, J., & Kirkeby-Hinrup, A. (eds.): Beyond the Neural Correlates of Consciousness. Psychology Press., 2019

Consciousness comes in degrees in the sense that the quality of conscious experiences — the appea... more Consciousness comes in degrees in the sense that the quality of conscious experiences — the appearance of their content — can gradually change along different dimensions like vividness, specificity and stability. These changes correspond to modulations of features of the underlying neural representations such as their intensity, precision and maintenance. This paper clarifies these correspondence relations and supports them by reviewing a series of novel findings from different strands on research focusing on wakeful perception, working memory, mental imagery, mind wandering and dreaming. These correspondence relations might allow us to move beyond traditional correlational claims with regard to consciousness, and establish tighter links between neural processes and subjective experiences.

White dreams are made of colours: What studying contentless dreams can teach about the neural basis of dreaming and conscious experiences

by Peter Fazekas and Georgina Németh

Sleep Medicine Reviews, 2019

Reports of white dreams, the feeling of having had a dream experience without being able to speci... more Reports of white dreams, the feeling of having had a dream experience without being able to specify this experience any further, make up almost one third of all dream reports, yet this phenomenon—until very recently— had not yet been in the focus of targeted investigations. White dreams are typically interpreted as forgotten dreams, and are sidelined as not being particularly informative with regard to the nature of dreaming. In this review article, we propose a paradigm shift with respect to the status of white dreams arguing that focusing on this phenomenon can reveal fundamental insights about the neural processes that occur in the dreaming brain. As part of this paradigm shift, we propose a novel interpretation of what white dreams are. This new interpretation is made possible by recent advancements in three different though interrelated fields focusing on dreaming, mental imagery, and wakeful perception. In this paper, we bring these different threads together to show how the latest findings from these fields fit together and point towards a general framework regarding the neural underpinnings of conscious experiences that might turn out to be highly relevant not just for dream research but for all aspects of studying consciousness.

Beyond the REM-NREM dichotomy: A multi-dimensional approach to understanding dreaming

by Georgina Németh and Peter Fazekas

Journal of Consciousness Studies, 2018

However, as subtle differences got into the forefront of enquiry, as, for example, in questions concerning between stage similarities and within stage differences of mentations, this methodology became insufficient. What recent findings and theoretical developments suggest is that understanding mental activity during sleep requires studying the fine-grained characteristics of the phenomenal features of individual dreams, which, in turn, demands identifying specific neural processes that might underly different characteristics of the experiences, and tracking their changes not just between, but also within standard sleep stages. The paper argues that such a shift of focus from describing global stages to understanding the significance of local changes results in a true paradigm shift in dream research that can break away from the tradition of thinking about sleep mentation in terms of discrete categories (e.g. REM/NREM, or high/low global activity level), and offers a novel way of looking at dreams (and other conscious experiences) as forming a multi-dimensional continuum.

According to the resulting Amplification View, attentional phenomena can be unified at the neural level as the consequences of the amplification of certain input signals of attention-independent perceptual computations. The paper demonstrates that this way of identifying the core realiser of attention is able to evade standard criticisms often raised against sub-personal accounts of attention. Moreover, the paper argues that this approach also reframes our thinking about the function of attention by shifting the focus from the function of selection to the function of amplification.

Three different arguments (a context-based, an organisation-based, and a constraint-based) are distinguished. After clarifying previously raised worries with regard to the first two arguments, the paper focuses on the newest version of the third argument that has recently been revived by William Bechtel. By using Bechtel's own case study, it is shown that not even reference to constraints can establish the causal autonomy of higher mechanistic levels.

Dream experiences and the neural correlates of perceptual consciousness and cognitive access

Two kinds of arguments are discussed, one that claims that the hypoactivity of the dorsolateral prefrontal cortex in REM sleep is directly relevant, and another that proposes that locating the neural correlates of dream experiences can indirectly inform the debate. It is argued that under closer reflection neither the classical claim about dorsolateral prefrontal cortex hypoactivity nor the more recent emphasis on general posterior hot zone activity during dreaming stand up to scrutiny. White dreaming is identified as the phenomenon that, nevertheless, holds the most promise to have an impact on the debate. Going beyond the topic if studying dreams can contribute to this debate, it is argued that cognitive access is not a monolithic phenomenon, and its neural correlates are not well understood. There seems to be a relevant form of cognitive access that can operate in the absence of activity in the dorsolateral prefrontal cortex, and maybe also in the whole frontal region. If so, then exclusive posterior activation during conscious experiences might very well be compatible with the hypothesis that perceptual consciousness requires cognitive access.

While the paper defends this general framework of thinking about aesthetic experiences, it argues that the specific characterization of aesthetic attention that has been proposed is unsatisfactory, since it is incompatible with recent empirical findings on how the allocation of attention works. The major aim of this paper is to explore empirically plausible ways of attending, and to determine what scientifically legitimate kind of attention could account for at least some of the distinctive features of aesthetic experiences. The paper argues that the rapid sequential reallocation of the focus of attention to different properties of a single object plays a crucial role in this context.

At the subjective level, we argue that conscious experiences can be degraded by being fragmented , less salient, too generic, or flash-like. At the representational level, we identify corresponding features of perceptual representations—their availability for working memory, intensity, precision, and stability—and argue that the mechanisms that affect these features are what ultimately modulate the degree of awareness. We conclude the paper by demonstrating why the original interpretations of certain empirical findings that apparently pose problems for our account are, in fact, flawed.

The Sensory Basis of the Epistemic Gap: An Alternative to Phenomenal Concepts

In recent years, defenders of physicalism have typically been relying on the so-called Phenomenal Concept Strategy (PCS) to avoid dualism. In this paper, we argue with PCS that cognitive-physicalistic explanations can account for the peculiarities of phenomenal character. However, we think that the conceptual features PCS investigates are not the genuine causes of the special characteristics of phenomenal consciousness but only symptoms, which can themselves be explained in terms of the features of the sensory-perceptual representations underlying conscious experiences, namely that some, but not all, of these states are representationally unstructured.

This way of thinking about attention has greater explanatory power, since it proposes a common implementation both for selection and modulatory effects, and it offers a unificatory perspective on the workings of perception and cognition.
