Twenty-one male managers who normally drink moderate amounts of alcohol participated in a placebo-controlled, double-blind, cross-over experiment. Subjects consumed either placebo or alcoholic drinks to attain a breath alcohol level of 0.10 during the evening before participation in Strategic Management Simulations. By the time of arrival at the simultaion laboratory on the following morning, breath alcohol levels were measured at 0.00. Questionnaire responses indicated considerable hangover discomfort. Responses to semantic differential evaluative scales suggested that research participants evaluated their own managerial performance in the simulation setting as impaired. However, multiple (validated) measures of decision-making performance obtained in the simulation task did not show any deterioration of functioning. Previous research had shown considerable performance decrements in the same task setting, while blood/breath alcohol levels ranged from 0.05 through 0.10%. Apparently, complex decision-making competence by persons who normally consume moderate amounts of alcohol may not be impaired by hangover caused by intoxication during the previous evening that remains at or below a blood alcohol level of 0.10.
21名平时适量饮酒的男性经理参与了一项安慰剂对照、双盲、交叉实验。在参与战略管理模拟前的晚上，受试者饮用安慰剂或酒精饮料，使呼气酒精浓度达到0.10。到第二天早上抵达模拟实验室时，测得呼气酒精浓度为0.00。问卷调查结果显示有相当程度的宿醉不适。语义差异评价量表的结果表明，研究参与者认为自己在模拟环境中的管理绩效受到了损害。然而，在模拟任务中获得的多项（经过验证的）决策绩效指标并未显示出功能有任何下降。先前的研究表明，在相同任务环境中，当血液/呼气酒精浓度在0.05%至0.10%之间时，绩效会有显著下降。显然，平时适量饮酒的人，其复杂决策能力可能不会因前一晚饮酒导致的宿醉而受损，只要血液酒精浓度保持在0.10及以下。
