通过两种启动刺激序列的方法（自启动和自动）和序列内的两个刺激间隔（ISI）来研究从顶点记录的听觉事件相关电位的习惯。在所有条件下，一连串 15 个刺激中的第二个刺激都会渐近形成习惯。列车中的第一个EP不受ISI影响，但列车启动程序直接影响N1的幅度和潜伏期、P2的潜伏期和P3的发生：所有措施在自动化条件下均大于自启动条件下。对于第二个到第十五个EP，启动列车的程序没有影响，但P2的幅度直接受ISI影响。
Habituation of auditory event-related potentials, recorded from the vertex, was investigated with two methods of initiating trains of stimuli (self-initiated and automated) and two interstimulus intervals (ISIs) within trains. In all conditions, habituation was asymptotic by the second stimulus in a train of 15 stimuli. The first EP in a train was unaffected by ISI, but the procedure for starting the train directly affected the amplitude and latency of N1, the latency of P2 and the occurrence of P3: all measures were greater in the automated condition than in the self-initiated. For the second through the fifteenth EPs, the procedure for starting the train had no effect, but the amplitude of P2 was directly affected by ISI.
