Previous research has revealed anticipatory pleasure deficits in people with schizophrenia and people with social anhedonia but who do not have schizophrenia. Prospection is an important component of anticipatory pleasure, but little is known about the role of prospection in social anhedonia. In 2 studies, we investigated prospection and anticipatory pleasure in people with schizophrenia and people with social anhedonia using an affective prospection task and a self-report measure, the Temporal Experience of Pleasure Scale (TEPS). In Study 1, we found that people with schizophrenia (n = 31) reported less TEPS anticipatory pleasure, generated less rich and vivid prospections, and reported less preexperiencing of future events than people without schizophrenia (n = 29). In Study 2, we found that people with social anhedonia (n = 34) reported less TEPS anticipatory pleasure, generated less rich prospections, and reported less pleasure and preexperiencing for future events than people without social anhedonia (n = 33). Taken together, prospection impairments and decreased anticipatory pleasure were observed in schizophrenia and social anhedonia. (PsycINFO Database Record (c) 2018 APA, all rights reserved)
