The impact of emotional faces on social motivation in schizophrenia.

Impairments in emotion recognition and psychosocial functioning are a robust phenomenon in schizophrenia and may affect motivational behavior, particularly during socio-emotional interactions. To characterize potential deficits and their interplay, we assessed social motivation covering various facets, such as implicit and explicit approach-avoidance tendencies to facial expressions, in 27 patients with schizophrenia (SZP) and 27 matched healthy controls (HC). Moreover, emotion recognition abilities as well as self-reported behavioral activation and inhibition were evaluated. Compared to HC, SZP exhibited less pronounced approach-avoidance ratings to happy and angry expressions along with prolonged reactions during automatic approach-avoidance. Although deficits in emotion recognition were replicated, these were not associated with alterations in social motivation. Together with additional connections between psychopathology and several approach-avoidance processes, these results identify motivational impairments in SZP and suggest a complex relationship between different aspects of social motivation. In the context of specialized interventions aimed at improving social cognitive abilities in SZP, the link between such dynamic measures, motivational profiles and functional outcomes warrants further investigations, which can provide important leverage points for treatment. Crucially, our findings present first insights into the assessment and identification of target features of social motivation.
