Abstract

This study examined the separate and combined effects of alcohol (0.0 or 0.5โ€‰g/kg) and alcohol expectancies (none or 2โ€“3 standard drinks) on riskโ€taking using a simulatedโ€driving lane choice task. In this task, riskโ€taking was operationalized as choosing a coneโ€defined lane with a higher relative probability of hitting a cone. When alcohol was received but not expected, the probability of a risky lane choice increased compared with when alcohol was neither expected nor received. However, when subjects both expected and received alcohol, the probability of a risky lane choice was significantly decreased compared with when alcohol was neither expected nor received. These findings suggest that the knowledge of dose received can differentially influence the pharmacological effect of alcohol on decisionโ€making. Copyright ยฉ 2003 John Wiley & Sons, Ltd.

The investigators studied the neural substrates of driving and their response to different blood alcohol concentrations (BACs), u

Objective Compared with non-bingers, binge drinkers are more likely to drive while intoxicated.
