睡眠剥夺会对前额叶皮层（PFC）产生负面影响，而执行功能在很大程度上依赖于PFC的活动。早期的研究主要集中在执行功能的子系统上，执行功能的测试显示出低信度和低效度。在本研究中，11名健康志愿者被剥夺了睡眠，并与11名健康对照进行了一晚SD对综合执行功能的影响的研究。采用SD后，受试者在生态有效测试（改进的六元素测试）中的表现显著受损。在精神运动警觉性、言语和视觉空间工作记忆方面没有组间差异。这扩展了先前关于SD对工作表现影响的知识，对于具有认知工作任务的个体来说可能特别重要。
The prefrontal cortex (PFC) is affected negatively by sleep deprivation (SD) and executive functioning is largely dependent on activity in the PFC. Earlier studies have focused on subsystems of executive functioning, and tests of executive functioning have shown both low reliability and low validity. In the present study, 11 healthy volunteers were sleep deprived and compared with 11 healthy controls in a study on effects of one night's SD on integrative executive functioning. Following SD, the performance of subjects on an ecologically valid test, the modified Six Elements Test, was significantly impaired. There were no group differences on psychomotor vigilance, verbal or visuo-spatial working memory. This extends previous knowledge of performance effects of SD, and may be of special importance for individuals with cognitive work tasks.
