Abstract

One prerequisite of using auditory event-related brain potentials (ERP) in developmental and clinical research is to determine their reliability. We examined the individual stability and test-retest reliability of the ERP responses elicited by repetitive, slightly deviant, and novel sounds over 3 months in healthy 6-year-old children. When broken down to 20 ms intervals, the standard-stimulus ERP responses shared > 77%, the deviant-stimulus responses 17-31%, and the novel-stimulus responses > 33% of the individual variation over the two testing sessions; the mean amplitude differences (novel/deviant-standard) did not change significantly between sessions. The sufficiently high individual stability of the ERP responses support the utility of these measurements for studying the effects of novel sounds in this age group.
