Abstract Details

2023, Doctor of Philosophy, Ohio State University, Psychology.
This dissertation investigates the neural representation of complex social information by employing multivariate methods such as functional connectivity classification analyses and intersubject representational similarity analyses (IS-RSA). The present research examines the functional network associated with social interactions as well as the association between neural similarity and individual differences in emotional reactivity and empathy. Study 1 utilizes multivariate pattern analyses (MVPA) to classify different categories of social interactions based on connectivity patterns between brain regions involved in social perception. Study 2 uses IS-RSA to investigate how individual differences in emotional reactivity modulates the neural representation of different social interactions. Study 3 explores how idiosyncrasies in behavioral measures of empathy are associated with neural synchrony during the observation of naturalistic social scenes depicting specific characters and various types of interactions. Study 1 demonstrates that contextual categorical information about social interactions is better classified by a network of regions rather than within a single region of interest. Studies 2 and 3 suggest that idiosyncrasies in trait-like attributes such as empathy or emotional reactivity reflects differences in neural representation of complex social information. This research contributes to our understanding of how social information is processed in the brain and sheds light on the impact of individual differences on social perception.
