Auditory event-related potentials (ERP, P3 components) were recorded from normal young adult subjects (17 to 37 yr) during two sessions scheduled 1 to 2 weeks apart. The test-retest intrasubject variability and the intersubject variability of the latency and amplitude values of components N1, P2, and P3 were investigated and analyzed. Between subjects, there was no evidence of systematic age-related changes of component latencies and amplitudes: the latency of P2 came closest to exhibit such an effect. Within subjects, there were no statistically significant changes of component latencies and amplitudes between test and retest, although ERP component latencies tended to be reduced on retest, especially the latency of P3.
在间隔1至2周安排的两次测试过程中，从正常年轻成人受试者（17至37岁）记录听觉事件相关电位（ERP，P3成分）。对N1、P2和P3成分潜伏期和波幅的重测受试者内变异性和受试者间变异性进行了调查和分析。受试者之间，没有证据表明成分潜伏期和波幅存在与年龄相关的系统性变化：P2的潜伏期最接近显示出这种效应。受试者内部，测试和重测之间成分潜伏期和波幅没有统计学上的显著变化，尽管ERP成分潜伏期在重测时往往会缩短，尤其是P3的潜伏期。
