Emotional memory bias in binge drinking women

Area of Science:

• Neuroscience
• Psychology
• Addiction Research

Background:

• Adolescence and emerging adulthood are characterized by heightened emotionality and memory recall.
• Binge drinking (BD) in emerging adults is associated with episodic memory deficits.
• Emotional functioning impairments are linked to alcohol use disorders, especially in females, but the emotional sphere in BDs remains under-explored.

Purpose of the Study:

• To investigate the impact of binge drinking on emotional episodic memory.
• To analyze these effects from a gender-specific perspective.

Main Methods:

• Longitudinal study of 180 university students (96 females) aged 18-20 over two years.
• Assessment of alcohol use and performance on an emotional list-learning task.
• Gender-stratified generalized linear mixed models analysis.

Main Results:

• Female binge drinkers exhibited a memory bias towards negative information and reduced recall of positive/neutral words.
• Female binge drinkers showed increased false alarms for negative distractors.
• No significant alcohol-related effects on emotional episodic memory were observed in males.

Conclusions:

• Female binge drinkers display a negative memory bias, impaired learning, and delayed recall due to negative content interference.
• These findings suggest difficulties in attentional disengagement from negative stimuli and reduced inhibitory control in female binge drinkers.
• This may indicate heightened vulnerability to alcohol-related emotional disturbances in women, warranting further research on emotional regulation and alcohol abuse escalation.
