Half of the search trials used arrays containing no target, providing the opportunity for \"giving up\" any search trial at the discretion of the participant. A monetary incentive/penalty system was used to define low- and high-criticality search trials. Search time, touch accuracy, the number of trials completed, percent \"give-ups,\" and hand travel time were all significantly degraded by the alcohol dosages used. An alcohol-by-criticality interaction was observed for percent give-ups, and an alcohol-by-target presence interaction was observed for mean search times.
