Oxytocin on Approach Bias and Craving

This will be a laboratory-based investigation of the behavioral and neural effects of intranasal oxytocin on craving for alcohol and approach bias in moderate to heavy alcohol using subjects. This study uses a within-subject, randomized, placebo-controlled, counterbalanced, crossover design to compare the effects oxytocin and placebo. In this way, all subjects will be scanned twice; once following oxytocin administration and once following placebo administration, and will complete a series of behavioral tasks (both in and out of the scanner) at both visits.
