Preresponse cues reduce the impairing effects of alcohol on the execution and suppression of responses.

The present study examined the effects of alcohol on the ability to execute and inhibit behavior in a context in which preliminary information signaled the likelihood that a response should be executed or suppressed. Social drinkers (N = 12) performed a cued go/no-go task that required quick responses to go targets and suppression of responses to no-go targets. Performance was tested under 3 doses of alcohol: 0.65 g/kg, 0.45 g/kg, and 0.0 g/kg (placebo). Alcohol had no effect on inhibition and execution when cues correctly signaled these actions. By contrast, alcohol impaired inhibition and execution in a dose-dependent manner when cues incorrectly signaled actions. These findings are consistent with a resource limitation account of alcohol impairment.
