在85分贝之前和之后测量心率。声音，1秒。持续时间。对120名新生儿（1-4日龄）进行了40次试验，刺激间隔为15、30或60秒。加速注意到所有的试验，并在老年人更大。反应递减出现在整个试验中，并没有相关的年龄，性别，或刺激间隔。它的结论是，减量是不是由于神经疲劳，但可能是一个指标的习惯性觉醒;结果表明，强直性觉醒反应习惯更容易比阶段性的。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Heart rate was measured before and after an 85-db. sound, 1 sec. in duration. 40 trials were given to each of 120 neonates (1-4 days of age), with interstimulus intervals of 15, 30, or 60 sec. Acceleration was noted on all trials, and was greater in older Ss. Response decrement appeared across trials, and was not related to age, sex, or interstimulus interval. It is concluded that the decrement is not due to neural fatigue, but may be an indicator of the habituation of arousal; the results suggest that the tonic arousal reaction habituates more readily than the phasic one.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
