Variability of single visual evoked potentials was investigated by means of three statistical tests sensitive to amplitude variations, gradual changes, and latency jitter, respectively. In a sample of (n = 78) normal children, a considerable number of inhomogeneous responders was found, and most prominent were gradual potential changes and latency jitter. Removal of latency jitter demonstrated that the gradual changes are not of latency type and only partly of the amplitude type. As found from empirical densities, there is strong indication that there were subpopulations differing in their response style. On the whole, however, it was concluded that there was no clear, interindividually stable type of response variation in these data.
通过分别对幅度变化、渐变和潜伏期抖动敏感的三种统计测试,研究了单个视觉诱发电位的变异性。在一个包含78名正常儿童的样本中,发现了相当数量的不均匀反应者,其中最突出的是电位渐变和潜伏期抖动。去除潜伏期抖动后表明,渐变不是潜伏期类型,只是部分是幅度类型。从经验密度中发现,有强烈迹象表明存在反应方式不同的亚群体。然而,总体而言,得出的结论是,这些数据中没有明确的、个体间稳定的反应变异类型。
