Summary

The study investigates the effects of alcohol consumption on social and individual behaviors using a within-subject design. Participants, aged 21-30, will attend two laboratory sessions approximately one week apart, participating as part of a dyad (pair). During one session, they will consume an alcoholic beverage, while in the other, they will receive a control beverage, with the order of conditions randomized. This design facilitates direct within-participant comparisons of behaviors and neural activity in intoxicated versus sober states.

To achieve these aims, the study employs EEG technology to explore intra-brain and inter-brain dynamics during social interactions. Additionally, validated self-report questionnaires will capture data on mood, social bonding, and other psychological variables. The findings are expected to enhance understanding of alcohol's role in social reward processes and contribute to developing evidence-based prevention and intervention strategies for alcohol use disorder.

Interventions

DRUG

Alcohol beverage

This intervention involves the administration of an alcohol beverage (vodka mixed with juice or soda) in a controlled laboratory setting, targeting a blood alcohol concentration (BAC) of 0.08%. The alcohol is consumed over a 36-minute period in three equal parts.

OTHER

Control - non alcoholic beverage

This intervention involves the administration of a non-alcoholic control beverage in a controlled laboratory setting. The beverage is matched in volume and palatability to the alcohol condition but co
