Emotion recognition in non-clinical eating psychopathology: A comparison between static faces and dynamic social interactions.

Emotion recognition deficits have consistently been reported in clinical and sub-clinical disordered eating.
However, most studies have used static faces, despite the dynamic nature of everyday social interactions. The
current aims were to confirm previous findings of emotion recognition deficits in non-clinical disordered eating
and to determine if these deficits would be more evident in response to static as compared to dynamic emotional
stimuli. We also aimed to establish if these emotion recognition deficits could be explained by comorbid psychopathology (depression, anxiety or alexithymia). Eighty-nine females were assigned to groups based on scores
on the Eating Disorders Inventory (EDI); high (n = 45) and low (n = 44). Participants were presented with
emotional faces and video clips portraying fear, anger, disgust, sadness, happiness, surprise and neutral affect. As
predicted, the high EDI group correctly recognised fewer emotional displays than did the low EDI group.
However, this deficit was not more evident for negative as opposed to positive emotions. Furthermore, the deficit
was not larger for static stimuli in comparison to dynamic. Overall emotion recognition accuracy was negatively
associated with Drive for Thinness, but not Bulimia or Body Dissatisfaction. Importantly, the emotion recognition deficits observed in the high EDI group and that were associated with eating disorder symptoms were
independent of depression, anxiety and alexithymia. Findings confirm that even minor elevations in disordered
eating are associated with poorer emotion recognition. This is important, as problems in recognition of the
emotional displays of others are thought to be a risk factor for clinical eating disorders
