Abstract

Establishing the reliability of event-related potentials is critical for future applications to biomarker development and clinical research. Few studies have examined the reliability of the contingent negative variation (CNV), and only in adults. The current study explored test-retest reliability of the visually evoked CNV and its embedded components, the O-wave and the E-wave, in children (7-13 years) and young adults (19-28 years) during a visual Go/No-Go task over 1-2 weeks. Test-retest reliability of the components was moderate for children, and low-to-moderate for adults. These findings were in contrast to previous work with adults showing moderate-to-high reliability of the auditory-evoked CNV.

摘要

确定事件相关电位的可靠性对于未来在生物标志物开发和临床研究中的应用至关重要。很少有研究考察关联性负变(CNV)的可靠性,且仅针对成年人。本研究在1至2周的视觉Go/No-Go任务中,探究了儿童(7至13岁)和青年成年人(19至28岁)视觉诱发CNV及其嵌入成分O波和E波的重测信度。这些成分的重测信度在儿童中为中等,在成年人中为低至中等。这些发现与之前针对成年人的研究结果形成对比,之前的研究表明听觉诱发CNV具有中等至高的可靠性。
