Emotion Recognition Biases in Alcohol Use Disorder

Area of Science:

• Neuroscience
• Psychology
• Social Cognition

Background:

• Alcohol use disorder (AUD) is linked to cognitive and emotional deficits.
• Difficulty recognizing emotional facial expressions is a known issue in AUD.
• The role of alcohol consumption versus mood in these deficits remains unclear.

Purpose of the Study:

• To investigate facial emotion recognition in individuals with AUD.
• To determine if deficits are linked to alcohol consumption severity or mood.
• To explore misidentification patterns in AUD.

Main Methods:

• Compared emotional face recognition in 19 AUD participants and 19 controls.
• Utilized the Cambridge Neuropsychological Test Automated Battery Emotion Recognition Task.
• Analyzed response latency, accuracy, and misidentification patterns, correlating with 90-day alcohol consumption.

Main Results:

• No significant differences in response latency or accuracy between groups.
• AUD participants showed distinct misidentification patterns, tending to label expressions as angry or disgusted.
• This bias towards anger/disgust misidentification positively correlated with recent alcohol consumption but not with anxiety or depression scores.

Conclusions:

• Individuals with AUD exhibit a bias towards perceiving facial expressions as hostile.
• This hostility bias is associated with alcohol consumption severity.
• Findings suggest disrupted social cognition in AUD, independent of mood changes.
