The purpose of this study is to determine whether changes in attention levels related to
taking a single dose of a medication called methylphenidate, also known as Ritalin, affects
responses to alcohol cues. The study will observe the effects of methylphenidate or a placebo
on attentional bias and craving responses to alcohol cues through fMRI, EEG, and behavioral
testing. Participants will be involved in one remote and two in-person sessions.
