Accuracy of recognition of neutral vs. positive/negative facial expressions by rrMDD-patients vs. controls for the facial expression recognition task. Figure shows the number of emotional expressions (neutral vs. positive vs. negative) accurately recognized and misclassified as the indicated emotion for rrMDD-patients and controls. For accurate responses, for positive vs. negative faces we found significant main effects for group (p = 0.011), for positive or negative vs. neutral, there was a significant main effect for valence (better classification of positive or negative than neutral faces; p < 0.001), with a valence*group interaction [positive (p = 0.017); negative (p = 0.002)]. For misclassifications, for positive vs. negative faces we found significant main effects for valence (p = 0.011); for negative vs. neutral, there was a significant main effect for group (p = 0.009), valence (p < 0.001) and the valence*group interaction (p = 0.002); for positive vs. neutral, there was a main effect for group (p = 0.003), valence (p < 0.001) and the valence*group interaction (p = 0.006).* p < 0.05; ** p < 0.01; rrMDD, remitted recurrent depressive disorder.
