ABSTRACT
Anticipatory and consummatory dissociation of hedonic experience may manifest as anhedonia in schizophrenia. However, it is unclear if this temporal dissociation of pleasure experience is also relevant in other symptoms like social anhedonia in the schizophrenia disorder spectrum. The present study applied two incentive delay tasks involving different incentive types (money vs. social affective images) to a sample of 28 participants with elevated social anhedonia (SocAnh) and 38 healthy controls from a population of 476 college students. The results showed that the SocAnh group had comparable anticipatory sensitivity and consummatory pleasure towards monetary incentives as the controls; but they exhibited significant decrease in both anticipatory sensitivity and consummatory experience to positive social affective images. These findings demonstrate the presence of a domain-specific deficit in people with social anhedonia towards social affective information, and suggest that incentive types could confound the findings on the dissociation of anticipatory vs. consummatory hedonic capacities.
