Abstract:
Different theoretical perspectives emphasize the significance of sensorimotor and visuospatial functions in shaping social perception, including theory of mind (ToM) and affect recognition (AR) abilities. This study aimed to investigate where in the brain cortical thickness (CT) predicts social perception, and which cognitive functions mediate such relationship. To these aims, we used a hierarchical analytical plan: Step 1 identified brain areas' CT that correlate with cognitive measures; Step 2 used stepwise regression to predict social perception outcomes (ToM and AR) from brain areas' CT; Step 3 assessed whether cognitive measures mediate the link between CT and social perception outcomes. The results showed that the CT of the left inferior frontal gyrus (IFG; pars triangularis) predicted both ToM and AR, while the CT of the right superior parietal gyrus (SPL) and of the right anterior occipital sulcus (AOcs) predicted only AR. Mediation models unveiled that visuo-constructive abilities and visual attention mediated the relationship between CT in these areas and social perception outcomes. These findings align with the role of the IFG in mentalizing abilities and underscore the involvement of SPL in visuospatial functions, including mental object rotation and spatial perspective-taking, which are essential for advanced social skills; the role of the AOcs in face processing was also highlighted. Importantly, the findings suggest that fronto-parietal areas are indirectly involved in social perception thorough their involvement in visuo-constructive abilities and visual attention.
