Deficits in recognizing emotional states in others have been observed in several psychiatric and neurological disorders. Findings from studies examining emotion processing in depressed patients, however, have been inconsistent. Moreover, the indications of a generalized or a specific emotion recognition impairment have been controversial. Thus, the purpose of the present study was to explore emotion recognition, and, specifically, affective prosody recognition, in a sample of depressed patients in remission.
Materials and methods
Seventeen patients with remitted depression (RD) and 20 healthy controls (HC), matched on age and education, were assessed with an affective prosody test (APT). In this test, 30 audiorecorded sentences of emotionally neutral content (e.g. “John is studying”) were presented with prosodic intonation portraying one of the basic emotions (happiness, sadness, surprise, fear, anger, as well as neutral) with five examples of each emotion.
Independent samples t-tests revealed no group main effect, either on their overall performance on the APT [t(35)=.611, p=.545], or on any particular emotion [happiness: t(35)=1.579, p=.087; sadness: t(35)=−.317, p=.753; surprise: t(35)=−1.006, p=.321; fear: t(35)=1.204, p=.237; anger: t(35)=−1.124, p=.268; neutral: t(35)=−1.262, p=.215]. For the patients, the rank order of the six emotions from the highest to lowest mean score was as follows: neutral intonation, anger, surprise, happiness, sadness, and fear, while for the healthy participants it was as follows: neutral intonation, happiness, fear, surprise, anger and sadness.
Although the two groups did not differ in their overall performance, patients with remitted depression showed a different pattern of emotion recognition, suggesting subtle deviation in the mode in which they identify emotional states. A larger sample of patients should be assessed, however, in order to strengthen the validity of our conclusion.
