被剥夺睡眠29~35h的受试者(男15例，女16例，平均年龄21.4岁)在逻辑推理和心境状态总心境的双相特征上存在显著缺陷。失眠导致的情绪缺陷与神经质、外向性和正常睡眠时间显著相关，情绪变化与控制源(LOC)得分之间存在显著的二次函数关系，即内部和极端外部因素在睡眠丧失后的情绪缺陷小于中度外部因素。以前的研究假设内部结构受到压力的影响较小，包括睡眠不足，我们认为极端外部环境可能更容易受到研究助理和睡眠实验室环境的积极激励作用的影响，包括参与各种社交休闲活动。回归分析表明，神经质(β=-0.40)和LOC的二次函数(β=0.39)是预测总体情绪变化的唯一有意义的人格因素。逻辑推理成绩的改变与总体情绪的改变显著相关(r=0.36)，但与人格变量无关。(C)2001爱思唯尔科学有限公司。保留所有权利。
Participants (n=31, males=15, females=16, mean age=21.4 years) deprived of sleep for 29-35 h showed significant deficits on logical reasoning and on bipolar Profile Of Mood States total mood. Deficits in mood due to sleep loss correlated significantly with neuroticism, extraversion and usual sleep duration, and there was a statistically significant quadratic function of mood change with locus of control (LOC) score, such that internals and extreme externals had a smaller mood deficit after sleep loss than did moderate externals. internals had been hypothesised from previous work to be less affected by stresses, including sleep loss, and we suggest that extreme externals may have been more susceptible to the positive motivating effects of the research assistants and the sleep laboratory environment, including involvement in various sociable leisure activities. Regression analysis showed that the only significant personality predictors of change in total mood were neuroticism (beta = -0.40) and the quadratic function of LOC (beta= 0.39). Change in logical reasoning performance was significantly correlated with change in total mood (r = 0.36): but with none of the personality variables. (C) 2001 Elsevier Science Ltd.
