Attempts to understand the mechanism by which alcohol expectancies might influence drinking have related activation of expectancies in memory to alcohol use. Limb of the blood alcohol curve, however, has not been considered. In the present study, 527 undergraduates completed the Anticipated Biphasic Alcohol Effects Scale and a drinking measure. Multidimensional scaling was used to map expectancies into memory network format, and likely activation of expectancies was empirically modeled. Heavier drinkers were most likely to activate positive and arousing expectancies associated with the ascending limb, whereas lighter drinkers were most likely to activate negative and sedating expectancies associated with the descending limb. These findings add to the literature suggesting that activation of expectancies in memory may be an important determinant of drinking behavior and a promising target for intervention strategies.
为理解酒精预期可能影响饮酒行为的机制，人们已将记忆中预期的激活与酒精使用联系起来。然而，血液酒精曲线的阶段尚未被纳入考量。在本研究中，527名本科生完成了预期双相酒精效应量表和一项饮酒测量。采用多维标度法将预期映射到记忆网络格式中，并对预期的可能激活进行了实证建模。饮酒量较大者最有可能激活与上升阶段相关的积极和兴奋预期，而饮酒量较小者最有可能激活与下降阶段相关的消极和镇静预期。这些发现为相关文献增添了内容，表明记忆中预期的激活可能是饮酒行为的一个重要决定因素，也是干预策略的一个有前景的目标。
