人们对早晨或晚上活动模式（“早起的鸟儿”和“夜猫子”）的偏好的生物学基础已经被假设，但仍然难以捉摸。作者报告说，与夜间类型相比，早晨类型的昼夜节律起搏器在时钟时间和唤醒时间方面都被拖到更早的时间。本研究探讨了早晨型人的生物钟可能提前的时间生物学机制。在为期一个月的住院研究中测量了固有周期，这是昼夜节律系统的基本属性。一部分参与者还评估了他们的昼夜节律。参与者在研究前完成了一份晨间-晚间问卷。昼夜节律周期与早晨-晚上、昼夜节律相位和清醒时间相关，表明昼夜节律起搏器的基本特性与早晨-晚上的行为特征相关。
The biological basis of preferences for morning or evening activity patterns ("early birds" and "night owls") has been hypothesized but has remained elusive. The authors reported that, compared with evening types, the circadian pacemaker of morning types was entrained to an earlier hour with respect to both clock time and wake time. The present study explores a chronobiological mechanism by which the biological clock of morning types may be set to an earlier hour. Intrinsic period, a fundamental property of the circadian system, was measured in a month-long inpatient study. A subset of participants also had their circadian phase assessed. Participants completed a morningness-eveningness questionnaire before study. Circadian period was correlated with morningness-eveningness, circadian phase, and wake time, demonstrating that a fundamental property of the circadian pacemaker is correlated with the behavioral trait of morningness-eveningness.
