FIGURE 1.

An illustration of a single trial in the social evaluation paradigm. On each trial, participants are presented with a photograph of a peer. The participant is asked to judge whether the peer would either like (accept) or dislike (reject) the participant. Based on judgment type (“YES” or “NO”) and feedback type (“YES” or “NO”), four possible feedback conditions were included: expected social acceptance (“YES–YES”), expected social rejection (“NO–NO”), unexpected social acceptance (“NO–YES”), or unexpected social rejection (“YES–NO”). This particular trial shows an example of unexpected social rejection.
