Theory of minds: managing mental state inferences in working memory is associated with the dorsomedial subsystem of the default network and social integration.

ABSTRACT: We often interact with multiple people at a time and consider their various points of view to facilitate smooth social interaction. Yet, how our brains track multiple mental states at once, and whether skill in this domain links to social integration, remains underspecified. To fill this gap, we developed a novel social working memory paradigm in which participants manage two- or four-people's mental states in working memory, as well as control trials in which they alphabetize two- or four-people's names in working memory. In Study 1, we found that the dorsomedial subsystem of the default network shows relative increases in activity with more mental states managed in working memory. In contrast, this subsystem shows relative decreases in activity with more non-mental state information (the
