Cooperative social interaction is critical for human social development and learning. Despite the importance of social interaction, previous neuroimaging studies lack two fundamental components of everyday face-to-face interactions: contingent responding and joint attention. In the current studies, functional MRI data were collected while participants(More)
High-functioning autism (ASD) is characterized by real-life difficulties in social interaction; however, these individuals often succeed on laboratory tests that require an understanding of another person's beliefs and intentions. This paradox suggests a theory of mind (ToM) deficit in adults with ASD that has yet to be demonstrated in an experimental task(More)
Converging theories and data suggest that atypical patterns of functional and structural connectivity are a hallmark neurobiological feature of autism. However, empirical studies of functional connectivity, or, the correlation of MRI signal between brain regions, have largely been conducted during task performance and/or focused on group differences within(More)
Reading about another person's beliefs engages 'Theory of Mind' processes and elicits highly reliable brain activation across individuals and experimental paradigms. Using functional magnetic resonance imaging, we examined activation during a story task designed to elicit Theory of Mind processing in a very large sample of neurotypical (N = 462)(More)
Joint attention behaviors include initiating one's own and responding to another's bid for joint attention to an object, person, or topic. Joint attention abilities in autism are pervasively atypical, correlate with development of language and social abilities, and discriminate children with autism from other developmental disorders. Despite the importance(More)
Theory of mind ('ToM') tasks elicit highly reliable neural activity across individuals and experimental paradigms. We compared activity in a very large sample of neurotypical ('NT', N=477) individuals, and a group of high functioning individuals with autism spectrum disorders ('ASD', n=27), using both region of interest ('ROI') and whole-brain analyses.(More)
Autism is characterized by atypical use of social communicative cues, such as another person's gaze or point. Despite these real-world difficulties, experimental manipulations often reveal minimal group differences. One factor that may contribute to this failure to find differences is the use of oversimplified and decontextualized social stimuli to examine(More)
These data were presented as a talk at the Abstract Joint attention behaviors include initiating one's own and responding to another's bid for joint attention to an object, person, or topic. Joint attention abilities in autism are pervasively atypical, correlate with development of language and social abilities, and discriminate children with autism from(More)
