We now know that that social cognition engages cortical regions quite distinct from those engaged in nonsocial aspects of cognition. Further, many cortical regions have been identified that conduct highly specific aspects of social cognition, from face perception, to language understanding, to theory of mind. This highly systematic cortical machinery is strikingly similar from one individual to the next, resulting in a richly detailed new map of social cognition in the brain. But while these discoveries constitute major progress, they are also the barest beginning, and reveal a vast landscape of new questions. What exactly is represented in each of these cortical regions, and how do the computations that produce those representations unfold over time? How are these regions structurally connected to each other and to the rest of the brain, and how do they interact with each other to produce real-world social cognition? And finally, how does the cortical organization of social cognition arise, both developmentally and evolutionarily? These questions will be harder to answer with current methods, but are well worth the effort. Vizcaya Museum is a villa and estate featuring extensive Italian Renaissance gardens. Thursday May 2, Afternoon 4:30pm Presidential Address Michael Tomasello Becoming Human: A Theory of Ontogeny Over the past two decades, my colleagues and I have documented many differences in the cognitive and social abilities of human children and their nearest great ape relatives. In this talk, I attempt to bring these studies together into a coherent theory of the ontogeny of uniquely human psychology. For each of eight uniquely human developmental pathways - four cognitive and four sociomoral – there are two key transitions: one at 9 months and one at 3 years. The hypothesis is that these transitions result from the maturation of new capacities for cooperation and social coordination with others - first joint intentionality with particular others and then collective intentionality with the group - which make possible new kinds of sociocultural experience and social self-regulation. 6:00pm Poster Session A & Welcome Reception at New World Center Miami Beach features radiant sun, surf and sand in close proximity to Art Deco architecture, nightclubs, and restaurants. Friday May 3, Morning 8:00am- 9:00am Breakfast 9:00am Symposium 1 Social Neuroscience Meets Network Neuroscience Avram Holmes: The functional connectomics of affective and psychotic pathology Converging evidence indicates that groups of patients with nominally distinct psychiatric diagnoses are not separated by sharp or discontinuous neurobiological boundaries. In healthy populations, individual differences in behavior are reflected in variability across the collective set of functional brain connections (functional connectome). These data suggest that the spectra of transdiagnostic symptom profiles observed in psychiatric patients may map onto detectable patterns of network function. To examine the manner through which neurobiological variation might underlie clinical presentation, we obtained functional magnetic resonance imaging (fMRI) data from over 1,000 individuals, including 210 diagnosed with a primary psychotic disorder or affective psychosis (bipolar disorder with psychosis and schizophrenia or schizoaffective disorder), 192 presenting with a primary affective disorder without psychosis (unipolar depression, bipolar disorder without psychosis), and 608 demographically matched healthy comparison participants recruited through a large-scale study of brain imaging and genetics. Here, we examine variation in functional connectomes across psychiatric diagnoses, finding striking evidence for disease connectomic “fingerprints” that are commonly disrupted across distinct forms of pathology and appear to scale as a function of illness severity. The presence of affective and psychotic illnesses was associated with graded disruptions in frontoparietal network connectivity (encompassing aspects of dorsolateral prefrontal, dorsomedial prefrontal, lateral parietal, and posterior temporal cortices). Conversely, other properties of network connectivity, including default network integrity, were preferentially disrupted in patients with psychotic illness, but not patients without psychotic symptoms. This work allows us to establish key biological and clinical features of the functional connectomes of severe mental disease. Nathan Spreng: Loneliness and meaning in life are reflected in the intrinsic network architecture of the brain Social relationships imbue life with meaning, whereas loneliness diminishes the sense of meaning in life. Yet the extent of interdependence between these psychological constructs remains poorly understood. Loneliness and meaning are associated with different patterns of functional connectivity; however, no studies have investigated this directly. We took a multivariate network approach to examine resting-state fMRI functional connectivity’s association with loneliness and meaning in a large cohort of adults (N=942). Loneliness and meaning in life were negatively correlated with one another. Functional brain regions were individually parcellated. Whole-brain measures of functional connectivity were then related to meaning and loneliness and a significant and reliable pattern was observed. Greater loneliness was associated with dense, and less modular, connections between default, frontoparietal and externally-directed attention and perceptual networks. A greater sense of life meaning was associated with increased, and more modular, connectivity between default and limbic networks. Low loneliness was associated with more modular brain connectivity, and lower life meaning was associated with higher between-network connectivity. These findings advance our understanding of loneliness and life meaning as distinct, yet interdependent, features of sociality. The results highlight a potential role of the default network as a central hub, providing a putative neural mechanism for shifting between feelings of isolation and purpose. Meghan Meyer: Social by Default: Characterizing the Social Functions of the Resting Brain Social neuroscience research has identified a set of medial frontoparietal brain regions that reliably engage during social cognition. At the same time, cognitive neuroscience research has shown that these regions comprise part of the default network, so named because they reliably activate during mental breaks ‘by default.’ While the anatomical similarity between the social brain and the default brain is well-documented, why this overlap exists remains a mystery. Does the tendency to engage these regions by default during rest play particular social functions and if so, what might these be? Here it is suggested that the default network performs two critical social functions during rest: social priming and social consolidation. These constructs will be defined, recently published empirical findings that support them will be reviewed, and directions for future research on the topic will be proposed. Emily Falk: Brain and Social Network Dynamics Associated with Susceptibility to Social Influence Brain dynamics shape learning and behavior, and social context shapes brain structure and function. In this talk, I will present evidence from a series of studies in adolescents linking brain network dynamics to individual differences in social network structure. Specifically, I will focus on how brain systems implicated in processing social rewards, social threats, and more general understanding of others’ mental states are associated with different types of social network properties, and in turn how these differences relate to adolescent susceptibility to social influence.
