Social judgments of faces are thought to be underpinned by two perceptual components: valence and dominance. Recent work using a standard key-press task to assess reward value found that these valence and dominance components were both positively related to the reward value of faces. Although bodies play an important role in human social interaction, the perceptual dimensions that underpin soci...

We propose a new type of social interaction as knowledge transactions. Tow agents consider to trade a set of Heterogeneous knowledge on which they have different value judgments. We aggregate by their different value judgments with threshold. The knowledge transactions are formulated as symmetric coordination games. We investigate what types of knowledge will be successfully traded through the ...

Whether social uses of language, in concert with their acquisition, are driven by the awareness of the social value assigned to linguistic variants remains unanswered. The present study examines how 185 French native speakers, aged from 2 to 6 years from different social backgrounds, produce and evaluate a well-known French phonological alternation, the liaison: obligatory liaisons, which are c...

It connects philosophers’ rejection of logical po...

However, the social information that we receive can be contradictory and vary in its reliability. Here, we tested whether the brain incorporates these statistics when judging value and confidence. Participants provided value judgments about consumer goods in the presence of online re...
