Implicit cognitions about alcohol have been shown to be an important predictor of alcohol use. Relatively little research has been conducted on racial/ethnic differences in implicit cognitions or changes in implicit cognitions while intoxicated. This study examined differences between Blacks and Whites in positive and negative implicit associations about alcohol, as measured by the Implicit Association Test (IAT) and tested differences in IAT scores when participants were sober and intoxicated.
One hundred thirty-five young adults (46% of Black descent) participated in an alcohol-administration study, receiving a moderate dose of alcohol (0.72 g/kg alcohol for men, 0.65 g/kg for women). The IAT was administered in two sessions, one in which alcohol was administered (30 minutes after alcohol consumption) and one in which it was not, approximately 1 week apart.
Repeated-measures mixed-factorial analyses of variance were conducted separately for positive and negative IAT scores. Blacks held lower positive and negative implicit cognitions about alcohol compared with Whites. Positive and negative IAT scores did not change as a function of intoxication. Positive explicit expectancies and self-reported past-month drinking behavior were related to positive IAT scores. Positive and negative IAT scores were also related to acute subjective response to alcohol, and this association differed by race.
Results extend previous studies by providing evidence for racial differences in implicit cognitions about alcohol and by showing the stability of the IAT while participants are intoxicated. Future studies are needed to determine what factors contribute to racial differences in implicit cognitions.
研究表明,对酒精的内隐认知是预测酒精使用的一个重要因素。关于种族/民族之间内隐认知的差异以及醉酒时内隐认知的变化,相对较少的研究。本研究通过内隐联想测验(IAT),考察了黑人和白人在对酒精的积极和消极内隐联想方面的差异,并测试了参与者在清醒和醉酒时 IAT 评分的差异。
135 名年轻成年人(46%为黑人血统)参与了一项酒精给药研究,接受了中等剂量的酒精(男性 0.72g/kg 酒精,女性 0.65g/kg 酒精)。IAT 在两个阶段进行,一个阶段给予酒精(在酒精摄入后 30 分钟),另一个阶段不给予酒精,大约相隔一周。
对正性和负性 IAT 评分分别进行重复测量混合方差分析。与白人相比,黑人对酒精的正性和负性内隐认知较低。正性和负性 IAT 评分不因醉酒而改变。正性的外显期望和自我报告的过去一个月饮酒行为与正性 IAT 评分相关。正性和负性 IAT 评分也与急性酒精主观反应有关,这种关联因种族而异。
结果提供了关于种族之间对酒精的内隐认知差异的证据,并表明参与者醉酒时 IAT 的稳定性,从而扩展了以前的研究。需要进一步的研究来确定哪些因素导致了种族之间内隐认知的差异。
