The purpose of this study was to evaluate CNV amplitude variability and its degree of covariance with the spontaneous EEG (quantified by FFT algorithm) and the reaction time. 14 healthy male subjects made from atypical for one hour, and they had to keep their eyes closed. Recordings were during this period. CNV experimental paradigm was performed (S1--S2 = 1500 msec). The major findings of this study were that: 1) the CNV amplitude progressively decreased during the first part of the test (habituation) and then tended to stabilize. While not correlated with the vigilance index of spontaneous EEG (alpha/theta + delta index) the CNV amplitude was significantly related to the alpha reactivity index (% alpha of spontaneous EEG--% alpha of the S1--S2 EEG), 2) the CNV slope (calculated by drawing two points situated at 600 msec and 1400 msec after S1) showed significant relationship to both these EEG indices and the reaction time. These data are discussed in terms of Cooper's distinction between "scopeutic" and "categoric" processes (1978) and in terms of the Tecce model of the CNV (1972).
本研究的目的是评估关联性负变（CNV）波幅变异性及其与自发脑电图（通过快速傅里叶变换算法量化）和反应时间的协方差程度。14名健康男性受试者闭眼静坐1小时，在此期间进行记录。采用CNV实验范式（S1 - S2 = 1500毫秒）。本研究的主要发现为：1）在测试的第一部分（习惯化）期间，CNV波幅逐渐降低，然后趋于稳定。虽然CNV波幅与自发脑电图的警觉指数（α/θ + δ指数）无关，但与α反应性指数（自发脑电图的α百分比 - S1 - S2脑电图的α百分比）显著相关；2）CNV斜率（通过在S1后600毫秒和1400毫秒处绘制两个点计算得出）与这两个脑电图指数以及反应时间均显示出显著关系。这些数据根据库珀（1978年）对“治疗性”和“分类性”过程的区分以及CNV的泰切模型（1972年）进行了讨论。
