Summary

This trial tests whether a short, computerized task — done on a smartphone or home computer three times a day for a week — can reduce smokers' automatic attention to cigarette cues and lower their cravings. Regular smokers aged 18–65 who smoke at least 10 cigarettes per day are randomly assigned to either an active training version or a control version. The goal is to see if repeatedly steering attention away from smoking-related images can weaken the pull of cravings.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
a computerized attention bias modification task
What this could lead to
If it works, this could offer a simple, at-home tool to help smokers manage cravings and support quitting.
What could go wrong
This is a small, early-stage trial with only 60 participants. The training is brief (one week), and any effects on cravings may not translate to long-term quitting success.
