The configuration and activation of memory networks have been theorized as mechanisms that underlie the often observed link between alcohol expectancies and drinking. A key component of this network is the expectancy "drunk." The memory network configuration of "drunk" was mapped by using cluster analysis of data gathered from the paired-similarities task (PST) and the Alcohol Expectancy Multi-Axial Assessment (AEMAX). A third task, the free associates task (FA), assessed participants' strongest alcohol expectancy associates and was used as a validity check for the cluster analyses. Six hundred forty-seven 18-19-year-olds completed these measures and a measure of alcohol consumption at baseline assessment for a 5-year longitudinal study. For both the PST and AEMAX, "drunk" clustered with mainly negative and sedating effects (e.g., "sick," "dizzy," "sleepy") in lighter drinkers and with more positive and arousing effects (e.g., "happy," "horny," "outgoing") in heavier drinkers, showing that the cognitive organization of expectancies reflected drinker type (and might influence the choice to drink). Consistent with the cluster analyses, in participants who gave "drunk" as an FA response, heavier drinkers rated the word as more positive and arousing than lighter drinkers. Additionally, gender did not account for the observed drinker-type differences. These results support the notion that for some emerging adults, drinking may be linked to what they mean by the word "drunk."
记忆网络的结构和激活被认为是潜在机制,解释了酒精期望与饮酒之间经常观察到的联系。该网络的一个关键组成部分是期望“醉酒”。通过对配对相似性任务(PST)和酒精期望多轴评估(AEMAX)收集的数据进行聚类分析,映射了“醉酒”的记忆网络结构。第三个任务,自由联想任务(FA),评估了参与者最强烈的酒精期望联想,并作为聚类分析的有效性检查。647 名 18-19 岁的参与者在基线评估时完成了这些测试以及一项酒精消费测试,以进行为期 5 年的纵向研究。对于 PST 和 AEMAX,“醉酒”在轻度饮酒者中主要与负面和镇静作用(例如“生病”、“头晕”、“困倦”)聚类,而在重度饮酒者中与更积极和兴奋作用(例如“快乐”、“性感”、“外向”)聚类,这表明期望的认知组织反映了饮酒者的类型(并且可能影响饮酒选择)。与聚类分析一致,在将“醉酒”作为 FA 反应的参与者中,重度饮酒者对该词的评价比轻度饮酒者更积极和兴奋。此外,性别并不能解释观察到的饮酒者类型差异。这些结果支持了这样一种观点,即对于一些刚成年的人来说,饮酒可能与他们对“醉酒”一词的含义有关。
