A psychological test battery comprising reasoning ability, name and number checking, letter cancellation and associative recall was administered to a group of 70 student nurses at 2-hr intervals from 0800 to 2000 to determine if their performance varied at different times of day. Simultaneously, their oral temperature was recorded. A 7 x 7 latin square design was utilized, and latin square repeated measure analysis of variance was employed. The results indicated variations in oral temperature as the day advanced. While accuracy of performance in cognitive tasks was found to be superior during the early morning, noon or early evening hours, the speed of performance was highest during the period from late-morning to late-evening.
对一组70名实习护士进行了一套心理测试，包括推理能力、姓名和数字核对、字母删除和联想记忆，测试时间从08:00至20:00，每隔2小时进行一次，以确定她们在一天中不同时间的表现是否有所不同。同时，记录她们的口腔温度。采用7×7拉丁方设计，并进行拉丁方重复测量方差分析。结果表明，随着一天时间的推进，口腔温度有所变化。虽然认知任务的表现准确性在清晨、中午或傍晚时分较高，但表现速度在上午晚些时候至傍晚时分最高。
