Modifying Alcohol Approach Motivations With tDCS and Cognitive Retraining
The overarching goal of this study is to determine whether combined cognitive training and
Transcranial Direct Current Stimulation (tDCS) reduces drinking in high-risk drinkers. To
this end, specific study purposes are: 1) replicate previous findings that cognitive
retraining reduces drinking levels, 2) test whether cognitive retraining can be enhanced with
tDCS, and 3) investigate the neural changes that result from cognitive retraining and tDCS.
We hypothesize that those participants who receive alcohol avoidance cognitive training will
have greater reductions in drinking. In turn, those participants who receive a higher level
of applied tDCS during alcohol avoidance response training will have better avoidance
learning, as well as, a larger reduction in drinking behavior. Finally, those participants
receiving a higher level of applied tDCS will have more neuronal response associated with
alcohol avoidance during the brain imaging session.
