目的:児童及び成人の随伴性陰性変動(CNV)とその後の脳波回復過程を研究することで、注意、認知などに関する脳機能の発達的変化を明らかにすること。対象:成人7名(平均260.57±21.1ヶ月)、児童8名(平均110.63±152ヶ月)。方法:被験者に刺激間間隔2秒、50%確率の音刺激弁別ボタン押し課題を課し、CNVを測定した。また、ウィスコンシンカード分類課題、WISC-III知能検査の「積み木模様」「数唱」「迷路」K-ABCの「位置探し」を施行した。そして、非標的時すなわちボタン押しをしなかった時のFz、Czにおける早期及び後期CNVの振幅、CNV解消時間を、成人群と児童群で比較した。そして、早期及び後期CNVの振幅、CNV解消時間と認知検査粗点の相関を見た。結果:早期及び後期CNV振幅は成人群-児童群間で有意差は認められなかった。Fzにおいて後期CNVが出現した成人7名と児童7名のCNV解消時間は、成人群が児童群よりも有意にCNV解消時間が短かった(p<0.01)。Czにおいて、後期CNVが出現した成人7名と子ども5名のCNV解消時間は、成人群-児童群の間で統計的有意差は認められなかった(t=-1.99,p=0.74)。早期及び後期CNVの振幅、CNVの解消時間と認知検査スコアの相関は、Czで導出された後期CNV振幅とWISC-IIIの「迷路」に有意な相関(r=.604,p<0.05)が認められたが、他では認められなかった。結論:CNV振幅には成人-児童間で明らかな差が認められないが、後期CNVが出現した対象者のCNV解消時間を比較するとFzにおいて、成人群が児童群よりも有意に短く、注意して反応した後の脳内の過程に児童-成人間で差があることが示唆された。そして、CNV振幅とその解消時間は加齢に伴う視覚記憶、聴覚記憶、実行機能課題などのスコア向上とは関係がないと推察された。

Objective: to study the response of children and adults to the following sexual activities (CNV) in order to learn about the information that can be achieved by computer. There were 7 adults (mean 260.57 ±21.1months) and 8 children (mean 110.63 ±152months). Methods: the subjects were stimulated at intervals of 2 seconds with a 50% certainty rate of sound stimulation to monitor the problem test and CNV test. There is a lot of information about the classification of WISC-III knowledge and knowledge, such as "wooden model", "number singing", "lost", "location exploration" and "implementation". The amplitudes of CNV in the early and later periods of Cz, the time of CNV elimination, and the comparison between adult children and normal children were recorded in the early and later periods of normal and non-normal time periods. The amplitude of CNV and the time of CNV cancellation in the early, early and later periods are known to be correlated with each other. Results: the amplitudes of CNV in the early and later stages were intentionally different between the population and the children. In the later phase of Fz CNV, 7 healthy adults and 7 healthy children were found to have CNV resolution time deficit, and adult children were interested in CNV resolution of time deficit reduction (pairltter0.01). In Cz and later CNV, 7 children and 5 children were found to have an intentional difference in the statistics of CNV elimination time and population-child group statistics (tweetel 1.99 page0.74). The amplitudes of CNV in early and later periods, the time of CNV cancellation, the amplitudes of CNV in the later period, the amplitudes of WISC-III and the "lost" waves in the later period of the wave were detected by Cz. Results: the amplitude of CNV showed that the difference between adult and child was detected. In the later stage of CNV, the time of CNV resolution was compared with that of Fz. The group of children in adult population was intentionally short-term, and pay attention to the instigation of child-to-adult screening in the post-test period. The signal and CNV amplitude cancellation time increases with the data log, the data log, and the mobile phone can monitor the data.
