This study was designed to examine whether the sleep-promoting effect of monotonous stimulation depends on individual differences in strength of the nervous system, as was suggested by Pavlov. Sixty male subjects were divided into three groups, depending on their score on the "strength of excitation" scale of the Strelau Temperament Inventory. Within each group, subjects were randomly assigned to be exposed to either a) a sequence of tones or b) "no tones" (i.e., a quiet room). Dependent variables were latencies to Sleep Stage 1 (SOL 1) and Sleep Stage 2 (SOL 2). The main effects of stimulation and strength of the nervous system were not statistically significant. However, there was a significant interaction between stimulation and strength for both dependent variables. "Weak" subjects tended to fall asleep more rapidly during monotonous stimulation, whereas the reverse was true of "strong" subjects. The results suggest that individual differences might play an important role in the development of sleep during monotonous stimulation.
本研究旨在检验如巴甫洛夫所指出的，单调刺激的促眠效果是否取决于神经系统强度的个体差异。60名男性受试者根据他们在斯特劳气质量表“兴奋强度”量表上的得分被分为三组。在每组中，受试者被随机分配接受以下两种情况之一：a）一系列音调，或b）“无音调”（即安静的房间）。因变量为进入睡眠第1阶段（SOL 1）和睡眠第2阶段（SOL 2）的潜伏期。刺激和神经系统强度的主效应无统计学意义。然而，对于两个因变量，刺激和强度之间存在显著的交互作用。“弱”受试者在单调刺激期间往往入睡更快，而“强”受试者则相反。结果表明，个体差异可能在单调刺激期间睡眠的形成中起重要作用。
