Abstract

In this paper the trial-to-trial variability of brain responses (as opposed to the non-event-related background variability) in flash-evoked potential experiments is investigated by means of two new statistical tests, proposed by M ocks et al. (1984). In two groups of normal children, a considerable number of inhomogeneous responders could be detected, and evidence was found that two different modes of response variability are independently present in the data. The paper also gives a precise description of the computing algorithm and an empirical validation of the applicability to EP data of the two tests.

摘要

在本文中,通过莫克斯等人(1984年)提出的两项新的统计测试,研究了闪光诱发电位实验中脑反应的逐次试验变异性(与非事件相关的背景变异性相对)。在两组正常儿童中,可以检测到相当数量的反应不均匀者,并且发现有证据表明数据中独立存在两种不同的反应变异性模式。本文还对计算算法进行了精确描述,并对这两项测试在诱发电位数据中的适用性进行了实证验证。
