Superior facial emotion recognition in adolescents with anorexia nervosa - A replication study.

Abstract

Anorexia nervosa (AN) has been associated with alterations in the processing of socio-emotional information, including impairments in the recognition of emotions in other people's faces. However, adolescents with AN might not show the impairments found in adult patients. The present study investigated facial emotion recognition in adolescents with AN, aiming to replicate our previous results of superior emotion recognition abilities in adolescents with AN compared to adolescents without mental disorders. Adolescent girls (12-18years) with AN (n=33) were compared to girls without mental disorders (n=41). Participants completed one task requiring identification of emotions (happy, sad, afraid, angry, neutral) in faces and one control task. As expected, adolescents with AN showed superior emotion recognition, with higher accuracy rates specifically for afraid faces. This is the first study replicating previous results on basic emotion recognition in adolescents with AN using (almost) the same methodology. The results suggest that, in contrast to adults, adolescents with AN do not show impairments in facial emotion recognition. The impairments may arise in the longer course of the illness, however, longitudinal studies are necessary to confirm this assumption.
