The effect of acute social stress on the recognition of facial expression of emotions

Abstract This study investigates the effect of acute social stress on the recognition of facial expression of emotions in healthy young men. Participants underwent both a standardized psychosocial laboratory stressor (TSST-G) and a control condition. Then, they performed a homemade version of the fa...

First, our results show a systematic increase in the intensity threshold for disgust following stress, meaning that the participants’ performance with this emotion was impaired.

Second, our results show a systematic decrease in the intensity threshold for surprise, therefore positively affecting the participants’ performance with that emotion. We suggest that the enhanced perception of surprise following the induction of social stress may be interpreted as an evolutionary adaptation, wherein being in a stressful environment increases the benefits of monitoring signals indicating the presence of a novel or threatening event.
