Summary

This study looked at how alcohol changes attention in 92 young adults aged 21-25 who drink regularly. Participants completed simple phone-based tasks before and after drinking a standard amount of alcohol in the lab, and also answered surveys on their phones over eight weekends. The goal was to see if alcohol-induced attention lapses lead to more risk-taking in real life.

What this could lead to
If successful, this could help explain how alcohol impairs attention and leads to risky behaviors, informing future prevention strategies.
What could go wrong
This is a small, completed observational study with no treatment aim. Results may not apply to all age groups or drinking patterns.
