Recordings of spontaneous electrodermal activity (EDA) were made in eight kittens, between 1 and 29 days of age, in order to obtain an estimation of reliability. Both frequency (number of SSPRs/min) and amplitude (in mV) of spontaneous electrodermal responses were computed during several waking-sleeping sessions. The results show that: (a) the reliability of records taken during the first week appears to be very low; (b) the frequency of SSPRs reaches the same level of stability as that of the adult at about three weeks of life; and (c) reliability of spontaneous EDA is considerably higher in sleeping than in waking kitten. The results are discussed in terms of ontogeny and 'trait' vs. 'state' characteristics of spontaneous EDA.
为了评估可靠性，对8只1至29日龄小猫的自发性皮肤电活动（EDA）进行了记录。在几次清醒 - 睡眠期间，计算了自发性皮肤电反应的频率（每分钟皮肤交感反应的次数）和幅度（以毫伏为单位）。结果表明：（a）第一周记录的可靠性似乎非常低；（b）皮肤交感反应的频率在出生后约三周达到与成年动物相同的稳定水平；（c）睡眠中小猫自发性EDA的可靠性明显高于清醒时。从个体发育以及自发性EDA的“特质”与“状态”特征方面对结果进行了讨论。
