145. Social Anhedonia: Evidence for the Subjective-Objective Paradox in a Live Social Interaction
Individuals with social anhedonia (SocAnh) report abnormalities in emotional experiences but inconsistently show objective deficits in emotional measures compared to controls. This “subjective-objective deficit paradox” has been reported in multiple domains of emotion processing. However, whereas previous studies have examined self-reports in response to hypothetical stimuli, we investigated subjective and objective experiences in response to a real social interaction. In the current study, participants were told they would engage in an “enjoyable” sharing task with another participant – in reality, a trained confederate – and were asked to predict their positive and negative affect in response to the interaction. Post-interaction, participants reported their experienced emotions. Consistent with the paradox, there was A) a trend for the SocAnh to predict (p =.22, d =.37) and experience (p =.1, d = .51) less positive affect, and B) to predict, (p =.03, d =.65) and experience (p =.03, d =.68) greater negative affect than controls. Concurrently, there were no group differences among behavioral indices of social engagement (as coded by blind raters), with the exception of people with SocAnh talking slightly less often (p =.04). These results are the first to extend the subjective-objective deficit paradox in schizotypy to a live social interaction.
