An examination of emotion perception ability and metacognitive functioning in high-dose alcohol intoxication

Background and aims: Alcohol-intoxication is linked to negative social behaviours, but the mechanisms underlying this relationship are poorly understood. We investigated the effects of high-dose alcohol intoxication on the ability to perceive a range of basic emotions (sad, happy, anger, disgust, fear, and surprise) of different intensities, and on self-appraisals of emotion perception ability (i.e., metacognitive judgments).

Method: Sixty-four participants consumed either an alcohol (mean BrAC = .077) or placebo beverage. The Emotion Recognition Task (ERT) was used to assess emotion perception ability, and participants provided confidence ratings when providing each emotion recognition response.

Results: Alcohol-intoxicated individuals demonstrated a reduced ability to detect fear and sadness at moderate-to-high levels of emotion intensity, and less overall insight into their ability to recognise emotions.

Conclusions: These results suggest that impaired ability to recognise expressions of fear and sadness in others – and lack of awareness of this impairment – may contribute to negative social behaviours associated with alcohol consumption.
