Alcohol Abuse
Conditions
Brief summary
Participants will undergo a single session of functional magnetic resonance imaging (fMRI)-based neurofeedback (approximately 1 hour). The investigators will assess their ability to regulate motivational networks of the brain during the exposure to alcohol cues and evaluate immediate effects on craving and cognitive bias for alcohol by administering a questionnaire and a Stroop task before and after the session.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Neurofeedback success (brain activation difference during neurofeedback and baseline blocks) | 1 day | This measure will be based on the analysis of participants' fMRI (functional magnetic resonance imaging) data, reflecting brain activation, during exposure to alcohol cues. Neurofeedback success will be defined as significant difference between activation levels (expressed as beta weights of a linear regression model) during the regulation periods compared to baseline. The significance will be determined by a t-test. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Drinking Urges Questionnaire as a measure of alcohol craving | 1 day | Measure of alcohol craving |
| Alcohol Stroop task as a measure of cognitive bias | 1 day | Measure of cognitive bias |
