INTRODUCTION
Sleep deprivation has detrimental effects on cognitive processes, including decision making. The present study investigated how 72 h of sleep deprivation influenced individual neural performance in the Iowa gambling task using event-related potential technology.
METHODS
Eleven healthy male adults who participated in our study were randomized to be either in group with 72 h of social isolation condition or 72 h of sleep deprivation condition.
RESULTS
Results showed that, in the feedback stage, the N amplitude was smaller in post-test than in pre-test for the sleep deprivation condition, especially in the frontal cortex. No significant difference between the pre-test and post-test condition was found in the social isolation condition.
CONCLUSION
These results suggested that 72 h of sleep deprivation affected an individual's response to feedback stimuli, causing the individual to evaluate the stimuli slowly.
引言
睡眠剥夺会对包括决策在内的认知过程产生不利影响。本研究使用事件相关电位技术，调查了72小时睡眠剥夺如何影响爱荷华赌博任务中的个体神经表现。
方法
参与我们研究的11名健康成年男性被随机分为72小时社会隔离组或72小时睡眠剥夺组。
结果
结果显示，在反馈阶段，睡眠剥夺组测试后的N波幅比测试前小，尤其是在额叶皮层。社会隔离组测试前和测试后条件之间未发现显著差异。
结论
这些结果表明，72小时睡眠剥夺会影响个体对反馈刺激的反应，导致个体对刺激的评估变慢。
