Depressive affect moderates the effects of biological sex on the recognition of facial emotion.

Females show a small processing advantage relative to males in the ability to identify facial expressions of emotion. In laboratory studies, this is expressed as a sex difference in the accuracy of discrimination or in recognition latencies (the time required to identify an expression). Reasons for the sex difference are not well-understood. In the current pilot study, young adults (N = 62) with and without mild to moderate symptoms of depression were asked to discriminate facial images of infants and toddlers expressing six cardinal emotions. Results showed that elevated depressive affect was associated with more rapid recognition of negative emotions by females, and with potentiation of the typically observed sex difference, compared with non-depressed observers. Differences in endogenous affective status might be one proximate factor contributing to a female advantage in emotion recognition.
