24名管理者通常每天摄入400至1,000毫克咖啡因，他们参加了全天的准实验模拟。在一项交叉、双盲设计中，他们做出了复杂的管理决策，要么使用典型的每日剂量的咖啡因治疗，要么使用超过每日摄入量的400毫克咖啡因治疗。研究了咖啡因处理对各种经验证的性能指标的影响。过量摄入咖啡因的影响是温和的。增加咖啡因促进了对传入信息的反应速度，但降低了机会的利用率。其他管理有效性指标（如活动、广度、战略和应急反应）无显著性。（PsycInfo数据库记录（c）2022阿帕，保留所有权利）
Twenty-four managers who normally consume between 400 and 1,000 mg of caffeine per day participated in all-day quasi-experimental simulations. In a crossover, double-blind design, they made complex managerial decisions either on treatment with their typical daily dose of caffeine or on treatment with 400 mg of caffeine in excess of daily consumption. The effect of caffeine treatment on various validated performance indicators was investigated. The impact of excess caffeine consumption was mild. Increased caffeine facilitated speed of response to incoming information but decreased utilization of opportunity. No significance was obtained for other measures of managerial effectiveness (such as activity, breadth, strategy, and emergency response).(PsycInfo Database Record (c) 2022 APA, all rights reserved)
