ALCOHOL'S ROLE IN DECISIONS TO DRIVE AFTER DRINKING

拟建项目的具体目的是通过实验设计来检验酒精对醉酒驾车决定的影响。参与者将喝含酒精、不含酒精或安慰剂的饮料，然后阅读一篇小短文，其中主角需要决定酒后是否开车。有三个版本的小插曲，不同的线索，鼓励或不鼓励演员开车。参与者将评估角色对酒后驾车的意图和态度，以及他们自己在相同情况下的意图和态度。根据酒精对认知加工的药理作用理论（Steele & Josephs, 1990; Taylor & Chermack, 1993）和酒精预期理论（Pernanen, 1993），将对酒精消费和酒精预期集效应进行研究。个体差异在认知功能和个人持有的酒精预期中的作用也将被调查。研究结果将有助于研究酒精对人类思维和行为的影响，以及制定防止醉酒驾驶的程序。

The specific aim of the proposed project is to examine alcohol's involvement in the decision to drive when intoxicated, using an experimental design. Participants will drink either an alcoholic, non- alcoholic, or a placebo beverage, then read a vignette in which the main character needs to decide whether or not to drive after drinking. There are 3 versions of the vignette, which vary cues which encourage or discourage the actor to drive. Participants will evaluate the character's intentions and attitudes about drinking and driving, as well as their own intentions and attitudes if they were in the same situation. Based on theories of alcohol's pharmacological effects on cognitive processing (Steele & Josephs, 1990; Taylor & Chermack, 1993) and alcohol expectancies (Pernanen, 1993), both alcohol consumption and alcohol expectancy set effects will be examined. The roles of individual differences in cognitive functioning and individually-held alcohol expectancies will also be investigated. Results will contribute to theories of alcohol's effects on human thinking and behavior, as well as to programming to prevent driving when intoxicated.
