Digital phenotypes of the diminished capacity for consummatory and anticipatory pleasure.

Diminished capacities to experience and anticipate pleasure have been differentially associated with psychopathology. However, measurement of this construct has been limited to self-report scales and complex behavioral tasks. In the present study, university students (N = 100) were categorized into low and high scorers on self-report measures of consummatory and anticipatory pleasure. Low and high scorers were then compared on the facial, vocal, and linguistic phenotypes of their descriptions of positive memories and future events. Scoring lower on consummatory pleasure was not associated with any differences in facial, vocal, or linguistic expression. Scoring lower on anticipatory pleasure was linked with decreased facial expression of happiness, mean vocal pitch, and amount of speech, as well as increased jitter and shimmer in the voice when describing positive future events. These results suggest that remote digital measures could be a useful adjunct for identifying individuals with diminished anticipatory pleasure.
