个体沿着一个连续的偏好昼夜活动水平，被称为早晨，晚上。晨性特征低的个体，即，更喜欢晚起和晚睡的人在冲动和寻求新奇的性格特征上得分更高。目前还没有研究探讨早-晚性格与冒险行为的相关结构之间的关系。因此，本研究检验了（1）早晨是否与自我报告的冒险行为和行为措施相关，以及（2）一晚的睡眠剥夺是否会导致冒险和寻求感觉的变化。54名健康成年人在摄入时进行晨间-夜间问卷调查，并在休息基线时进行简短感觉寻求量表、风险评估量表和气球模拟风险任务，再次在23小时睡眠剥夺后，最后在12小时恢复睡眠后。较低的晨起分数与休息时较高的自我报告的总冒险倾向相关（p
Individuals differ along a continuum of preference for diurnal activity level, known as Morningness-Eveningness. Individuals low in Morningness traits, i.e., preferring later awakening and bed times, have been shown to score higher on personality traits of impulsiveness and novelty-seeking. No studies have yet examined the association between Morningness-Eveningness and the related construct of risk-taking. Therefore, the present study examined (1) whether Morningness was correlated with self-reported and behavioral measures of risk-taking, and (2) whether one night of sleep deprivation would produce changes in risk-taking and sensation-seeking. 54 healthy adults were administered the Morningness-Eveningness Questionnaire at intake, and administered the Brief Sensation Seeking Scale, Evaluation of Risks Scale, and Balloon Analog Risk Task at rested baseline, again following 23 hr. of sleep deprivation, and finally after a 12-hr. period of recovery sleep. Lower Morningness scores were associated with higher self-reported total risk-taking propensity when rested (p
