摘要: Theory of mind (ToM)�or thinking about the mental states othersis a cornerstone successful everyday social interaction. However, brain bases ToM are most frequently measured via explicit laboratory tasks that pose direct questions (e.g. �In this story, what does Steve think Julia believes?�). Neuroanatomical measures may provide way to explore individual differences in more naturalistic mentalizing. In current study, we examined relation between cortical thickness and spontaneous using novel Spontaneous Mind Protocol (STOMP), which participantsspontaneous descriptions beliefs, emotions goals characters videos. We administered standard STOMP young adults (aged 18-26 years) collected structural magnetic resonance imaging data from subset these participants. The produced robust variability was correlated with performance on traditional tasks. Further, unlike tasks, related for set regions have been functionally linked processing. These findings offer insight into mentalizing performance, implications both typical atypical populations.
