Tolerance To The Impairing Effects Of Alcohol On The Inhibition And Activation Of Behavior, Erik Wayne Ostling

University of Kentucky Master's Theses

Moderate doses of alcohol impair response inhibition activation. Recent work has shown that, during a single dose, response inhibition recovers from the impairing effects of alcohol more slowly than response activation. Evidence for a lag in tolerance development to inhibitory versus activational mechanisms suggests that, as blood alcohol declines, drinkers’ response inhibition might continue to be impaired, despite the recovery of response activation. However, this has not been studied across repeated doses. This study examined how cross-session tolerance to alcohol develops differentially between response activation and inhibition. Thirty-two healthy adults performed a cued go/no-go task that measured response activation and …
