这项研究调查了16名健康的晨型受试者和13名晚型型受试者的主观情绪的24小时变化，这些受试者的口腔温度曲线在一天中达到最大值。受试者被指示使用睡眠-唤醒日志，在其中，他们连续两周每天记录自己的情绪和警觉性评级。对于情绪和警觉性，方差分析表明早晚类型和一天中的时间之间存在显著的交互作用。结果表明，健康人的情绪存在明显的日变化，晨型和晚型的情绪日变化不同。
This study investigated a 24-hour variation of subjective mood in 16 healthy Morning-type and 13 Evening-type subjects as defined by the time of day at which their oral temperature curve reached its maximum. The subjects were instructed to use a sleep-wake logbook, in which they kept daily records of the ratings of their mood and alertness for a period of two consecutive weeks. For mood as well as for alertness analysis of variance indicated significant interactions between Morning and Evening-types and time of day. It is concluded that a pronounced diurnal variation of mood can be observed in healthy individuals, which differs between Morning-type and Evening-type subjects.
