本研究的目的是以纵向的方法研究人在生命的前六年的SWC发展。六名在圣保罗大学同一所幼儿园上学的男孩参加了这项研究。数据收集在五个不同的场合，从第二至第六年的生活。在每种情况下，由幼儿园的观察员和父母在家中连续7天（周日至周六）跟踪睡眠/觉醒行为。获得所有受试者的平均总睡眠持续时间以及平均日间睡眠持续时间（从7 AM到7 PM的发作）和夜间睡眠持续时间（7 PM到7 AM）。通过ANOVA对重复测量的数据进行比较，并使用Fast进行处理。傅立叶变换以获得睡眠/清醒振荡的功率谱。结果提交给测试的复合周期，以检测频谱的重要组成部分。该测试为每个频率生成一个值（Y），表示该频率对整体节律性的贡献。结果显示，年龄对总睡眠时间有影响（p
The aim of this work is to study the human' SWC development in the first six years of life, in a longitudinal approach. Six boys, attending the same kindergarten at University of Sao Paulo, participated in the study. Data were collected on five different occasions, from the second to the sixth year of life. On each occasion, the sleep/wake behavior was followed for seven consecutive days (Sunday to Saturday) by an observer at the kindergarten and at home by the parents. Mean total sleep duration as well mean diurnal sleep duration (episodes from 7 AM to 7 PM) and night sleep duration (7 PM to 7 AM) were obtained for all subjects. Data were compared by ANOVA for repeated measures and processed using the Fast. Fourier Transform to obtain the power spectrum of the sleep/wake oscillations. Results were submitted to a test of compound periodicities, to detect the significant components of the spectrum. This test generates, for each frequency, a value (Y), which represents the contribution of this frequency to overall rhythmicity. Results showed an age effect on total sleep duration (p
