title: Social and physical anhedonia and valence and arousal aspects of emotional experience.
abstract: Two studies examined whether self-reported anhedonia is associated with 2 facets of emotional experience, valence and arousal. In Study 1, in multiple assessments of emotional experience (e.g., naturalistic and lab contexts and social and nonsocial situations), people with elevated social anhedonia (n = 40) reported less intensity of positive affect than both controls (n = 30) and people with elevated perceptual aberration-magical ideation (n = 29). Social anhedonia was also associated with providing less emotional content when describing what it is like to experience positive situations. In contrast, both social anhedonia and perceptual aberration-magical ideation were associated with increased frequency of negative affect for their daily experiences. Moreover, social anhedonia was not associated with a decrease specifically in high-arousal emotions. In Study 2 (n = 339), social and physical anhedonia (but not perceptual aberration-magical ideation) were again associated with decreased self-reported positive affect to lab stimuli. In these studies, results were not statistically accounted for by personality, current mood, or current distress. Overall, results suggest anhedonia may be associated with a general decrease in self-reported positive affect intensity.
