Male subjects scoring high (n=17) or low (n=14) on the Maudsley Neuroticism scale were randomly assigned to a positive (n=17) or negative (ego threat) (n=14) presleep condition and then slept a single night in the laboratory. The negative condition elicited significantly more rapid eye movement activity (REM density) than did the positive condition (pless than.03). There was a significant interaction for Groups X Conditions (pless than.007) indicating that low neuroticism subjects had greater REM density in the negative condition, and less REM density in the positive condition, compared to high neuroticism subjects under either condition. The low neuroticism subjects in the negative condition showed a discrepancy between greater REM density but less admission of stress on a presleep mood questionnaire compared to high neuroticism subjects. These results support the hypothesis that REM density is a correlate of stress-induced arousal that is subject to the modifying effects of individual differences.
在莫兹利神经质量表上得分高(n = 17)或低(n = 14)的男性受试者被随机分配到积极(n = 17)或消极(自我威胁)(n = 14)的睡前条件下,然后在实验室睡一晚。消极条件比积极条件引发了显著更多的快速眼动活动(快速眼动密度)(p <.03)。组×条件存在显著交互作用(p <.007),表明与两种条件下的高神经质受试者相比,低神经质受试者在消极条件下有更高的快速眼动密度,而在积极条件下快速眼动密度更低。与高神经质受试者相比,消极条件下的低神经质受试者在快速眼动密度更高但在睡前情绪问卷上对压力的承认更少之间存在差异。这些结果支持了这样的假设,即快速眼动密度是压力诱发觉醒的一个相关因素,且受到个体差异的调节作用。
