The neural representation of social status in the extended face‐processing network

Social status is a salient cue that shapes our perceptions of other people and ultimately guides our social interactions. Despite the pervasive influence of status on social behavior, how information about the status of others is represented in the brain remains unclear. Here, we tested the hypothesis that social status information is embedded in our neural representations of other individuals. Participants learned to associate faces with names, job titles that varied in associated status, and explicit markers of reputational status (star ratings). Trained stimuli were presented in an functional magnetic resonance imaging experiment where participants performed a target detection task orthogonal to the variable of interest. A network of face‐selective brain regions extending from the occipital lobe to the orbitofrontal cortex was localized and served as regions of interest. Using multivoxel pattern analysis, we found that face‐selective voxels in the lateral orbitofrontal cortex – a region involved in social and nonsocial valuation, could decode faces based on their status. Similar effects were observed with two different status manipulations – one based on stored semantic knowledge (e.g., different careers) and one based on learned reputation (e.g., star ranking). These data suggest that a face‐selective region of the lateral orbitofrontal cortex may contribute to the perception of social status, potentially underlying the preferential attention and favorable biases humans display toward high‐status individuals. Using multivoxel pattern analysis (MVPA), this study found that face‐selective voxels in the lateral orbitofrontal cortex (lOFC), a region involved in social and nonsocial valuation, could decode faces based on trained social status information. These data suggest that a face‐selective region of the lOFC may contribute to the perception of social status, potentially underlying the preferential attention and favorable biases humans display toward high‐status individuals.
