The purpose of the present study was to investigate the combined effects of alcohol, instructions regarding the alcohol content of a beverage, and the rate of comsumption on motor performance. To provide an expanded replication of Vuchinich and Sobell's study, pursuit rotor-tracking (alone and as part of a divided-attention task) and choice reaction-time performance (as part of the divided-attention task) were assessed. A moderate dose of alcohol had an adverse effect, the rate of consumption had little effect, and instructions concerning the alcohol content of the beverage consumed had no effect, on motor performance.
