We tested 2 competing theories about the effects of alcohol on intentions to engage in risky behavior. Disinhibition predicts that intoxicated people will exhibit risky behavior regardless of environmental cues, whereas alcohol myopia (C. M. Steele & R. A. Josephs, 1990) predicts that intoxicated people will be more or less likely to exhibit risky behavior, depending on the cues provided. In 4 studies, we found an interaction between intoxication and cue type. When impelling cues were present, intoxicated people reported greater intentions to have unprotected sex than did sober people. When subtle inhibiting cues were present, intoxicated and sober people reported equally cautious intentions (Studies 1-3). When strong inhibiting cues were present, intoxicated people reported more prudent intentions than did sober people (Study 4). We suggest that alcohol myopia provides a more comprehensive account of the effects of alcohol than does disinhibition.
我们检验了关于酒精对参与危险行为意图影响的两种相互竞争的理论。去抑制理论预测,醉酒者会不顾环境线索而表现出危险行为,而酒精近视理论(C.M. 斯蒂尔和R.A. 约瑟夫斯,1990)预测,醉酒者表现出危险行为的可能性或多或少取决于所提供的线索。在4项研究中,我们发现了醉酒状态与线索类型之间的相互作用。当存在促进行为的线索时,醉酒者报告的无保护性行为意图比清醒者更强。当存在微妙的抑制性线索时,醉酒者和清醒者报告的意图同样谨慎(研究1 - 3)。当存在强烈的抑制性线索时,醉酒者报告的意图比清醒者更谨慎(研究4)。我们认为,与去抑制理论相比,酒精近视理论对酒精的影响提供了更全面的解释。
