While recent research suggests that people with schizophrenia anticipate less pleasure for non-social events, considerably less is known about anticipated pleasure for social events. In this study, we investigated whether people with and without schizophrenia differ in the amount and updating of anticipated pleasure over the course of repeated interactions as well as the influence of emotional displays. Thirty-two people with schizophrenia and 29 controls rated their anticipated pleasure over the course of repeated interactions with smiling, scowling, or neutral social partners that had either positive or negative outcomes. Compared to controls, people with schizophrenia anticipated a lower amount of pleasure during interactions with smiling, but not neutral social partners that had positive outcomes. However, the groups did not differ in the amount or updating of anticipated pleasure during interactions that had negative outcomes. Both groups anticipated more pleasure over the course of repeated interactions with smiling partners and less pleasure over the course of repeated interactions with scowling partners compared to interactions with neutral partners. We discuss how less anticipated pleasure for interactions with smiling social partners may be linked to difficulties in social engagement among people with schizophrenia.
