This chapter traces the history of research on information and communication technologies in daily life, with an eye toward measurement and conceptualization problems. Similar to the new technologies of earlier eras, the prominence of current habitual manifestations has raised challenging questions for both researchers and societies. These newer media habits may exaggerate core habitual mechanisms by providing a wide spectrum of potential cues, possible contexts, and complex rewards-resulting in dynamic habits that appear to be "special". We discuss how research on technology habits serves to uncover the assumptions, boundaries, and moderators of habit, while calling for a revised approach to address recurring problems in the literature. Altogether, the chapter clarifies how technology habit research contributes to a broader understanding of habitual behaviour.

This study attempts to tease out some of these differences through multiple analytical strategies and samples. Drawing on theoretical expectations about the affordances, motivations, and cognition of mobile use, we investigate who uses mobile Facebook, why they use it, and how they use it. To do this, we first compare those who use Facebook only on a PC with those who also use the service on mobile devices. Then, in order to quantify mobile Facebook use, we propose a new set of survey measures to tap into more and less mobile users among the sample of people who access Facebook through multiple modes. These questions serve to validate measures of mobile Facebook use, and allow us to examine how patterns of use relate to user motivations and experiences. Findings revealed important differences between PC-only and mobile users as well as a distinct and reliable measure of mobileness. Whereas motivations for Facebook use did not differ across users, more habitual and absorbing use of Facebook was strongly, positively associated with mobile

Social Networks and Cognition by Joseph Bayer

Nonetheless, there is minimal research examining how social challenges such as exclusion alter ensuing interactions with personal ties. Here, we tested whether being excluded during a social interaction changed which relationships are most salient in an ostensibly unrelated, online news sharing task. Across three operationalizations of tie strength, exclusion (vs. inclusion) increased sharing to close friends, but (unexpectedly) decreased sharing to close family members. The findings provide preliminary evidence that negative encounters may shift attention toward certain types of network ties and away from others. Future work is needed to examine how social experiences influence personal network scope-i.e., who comes to mind-in the background of daily life.

Responding to this void, we describe the real-time construction of cognitive social networks. First, we outline the types of relational structures that comprise momentary networks, distinguishing the roles of personal relationships, social groups, and mental sets. Second, we discuss the cognitive mechanisms that determine which individuals are activated-and which are neglected-through a dynamic process. Looking forward, we contend that these overlooked mechanisms need to be considered in light of emerging network technologies. Finally, we chart the next steps for understanding social-network cognition across real-world contexts, along with the built-in implications for social resources and intergroup disparities.

In particular, individual differences in the tuning of biological systems that respond to social threats may motivate individuals to seek out differently structured social environments. Drawing on a sample of adolescent males who underwent fMRI brain imaging (n = 74) and contributed Facebook data, we examined whether biological responses to a common scenario-being excluded from an activity with peers-was associated with their social network structure. We find that neural responses during social exclusion in a priori hypothesized "social pain" regions of the brain (dACC, AI, subACC) are associated with the density and transitivity of core friendship networks. These findings suggest that neural reactivity to exclusion may be one factor that underlies network "safety". More broadly, the study shows the potential of linking social cognitive tendencies to social structural properties.

Disruption of ties through social exclusion has a marked effect on our thoughts and feelings; however, such effects can be tempered by broader social network resources. Here, we use fMRI data acquired from 80 male adoles- cents to investigate how social exclusion modulates functional connectivity within and across brain networks involved in social pain and understanding the mental states of others (i.e., mental- izing). Furthermore, using objectively logged friendship network data, we examine how individual variability in brain reactivity to social exclusion relates to the density of participants’ friendship networks, an important aspect of social network structure. We find increased connectivity within a set of regions previously iden- tified as a mentalizing system during exclusion relative to inclusion. These results are consistent across the regions of interest as well as a whole-brain analysis. Next, examining how social network char- acteristics are associated with task-based connectivity dynamics, we find that participants who showed greater changes in connectivity within the mentalizing system when socially excluded by peers had less dense friendship networks. This work provides insight to un- derstand how distributed brain systems respond to social and emo- tional challenges and how such brain dynamics might vary based on broader social network characteristics.

Do individuals with more opportunities to connect otherwise unconnected others—high information brokers—use their brains differently than low information brokers when making recommendations? We test the hypothesis that those with more opportunities for information brokerage may use brain systems implicated in considering the thoughts, perspectives, and mental states of others (i.e. 'mentalizing') more when spreading ideas. We used social network analysis to quantify individuals' opportunities for information brokerage. This served as a predictor of activity within meta-analytically defined neural regions associated with mentalizing (dorsomedial prefrontal cortex, temporal parietal junction, medial prefrontal cortex, /posterior cingulate cortex, middle temporal gyrus) as participants received feedback about peer opinions of mobile game apps. Higher information brokers exhibited more activity in this mentalizing network when receiving divergent peer feedback and updating their recommendation. These data support the idea that those in different network positions may use their brains differently to perform social tasks. Different social network positions might provide more opportunities to engage specific psychological processes. Or those who tend to engage such processes more may place themselves in systematically different network positions. These data highlight the value of integrating levels of analysis, from brain networks to social networks.
