25位平均每天摄入575毫克咖啡因的经理参加了两个复杂的模拟实验。采用双盲交叉设计来评估正常咖啡因摄入与咖啡因剥夺对七种有效管理有效性措施的影响。来自咖啡因戒断问卷的数据表明，咖啡因戒断后会感到不适。在“正常”咖啡因摄入水平下，收缩压升高，但在咖啡因摄入不足的情况下，收缩压迅速下降，并保持在较低水平。几项管理绩效指标表明，咖啡因剥夺会降低管理效率。与之前对简单任务设置的研究相比，认知效率（在复杂任务执行期间）降低了。然而，一项需要相对高水平认知努力的战略绩效测量显示，咖啡因剥夺没有影响。
Twenty-five managers who reported an average daily caffeine consumption of 575 mg participated in two complex simulations. A double-blind cross-over design was employed to assess the effects of normal caffeine consumption versus caffeine deprivation upon seven validated measures of managerial effectiveness. Data from a Caffeine Withdrawal Questionnaire indicated discomfort upon deprivation. Systolic blood pressure increased during “normal” caffeine consumption levels but fell quickly and remained lower during deprivation. Several measures of managerial performance indicated decreased effectiveness upon caffeine deprivation. In contrast to prior research from simpler task settings, cognitive effectiveness (during complex task performance) was diminished. However, a measure of strategic performance which requires a relatively high level of cognitive effort showed no impact of caffeine deprivation.
