本研究旨在探讨睡眠剥夺对冲动行为的影响。患有冲动控制障碍的患者经常报告睡眠问题，即使在健康的个体中，睡眠剥夺也会损害认知，决策，也许还有冲动控制。为了描述睡眠不足对特定形式的冲动行为的影响，我们测试了过夜的影响，监测睡眠剥夺对健康志愿者冲动性和认知的影响。10名男性和10名女性以随机顺序完成了两个24小时的会议，其中他们要么被允许正常睡眠，要么整夜保持清醒。在睡觉或不睡觉后的第二天上午8：30和6：15，参与者被测试了气球锚固风险任务（BART），经验折扣任务，调整量延迟和概率折扣任务，以及停止任务。参与者还完成了情绪问卷和自动神经心理评估矩阵（ANAM）。睡眠剥夺并不影响大多数冲动行为指标。然而，在BART上，睡眠剥夺降低了女性的风险，但不是男性。睡眠剥夺产生了预期的主观疲劳增加，并在ANAM上的注意力和认知效率的措施上表现受损。结果表明，睡眠不足并不会特别增加冲动行为，但可能会对男性和女性的风险承担产生不同的影响。(C)2007年爱思唯尔公司All rights reserved.
The purpose of this study was to examine the effects of sleep deprivation on impulsive behavior. Patients with impulse control disorders often report sleep problems, and sleep deprivation even in healthy individuals impairs cognition, decision-making, and perhaps impulse control. To characterize the effects of sleep loss on specific forms of impulsive behavior, we tested the effects of overnight, monitored sleep deprivation on measures of impulsivity and cognition in healthy volunteers. Ten men and ten women completed two 24 h sessions in random order, in which they were either allowed to sleep normally or remained awake all night. At 8:30 am and 6:15 pin on the day after sleep or no sleep, participants were tested on the Balloon Analogue Risk Task (BART), the Experiential Discounting Task, the Adjusting Amount Delay and Probability Discounting Task, and the Stop Task. Participants also completed mood questionnaires and the Automated Neuropsychological Assessment Matrix (ANAM) throughout the course of the day. Sleep deprivation did not affect most of the measures of impulsive behavior. However, on the BART, sleep deprivation decreased risk taking in women, but not men. Sleep deprivation produced expected increases in subjective fatigue, and impaired performance on measures of attention and cognitive efficiency on the ANAM. The results indicate that sleep deprivation does not specifically increase impulsive behaviors but may differentially affect risk taking in men and women. (C) 2007 Elsevier Inc. All rights reserved.
