Abstract: 脳の事象関連電位である随伴性陰性変動(CNV)の解消過程の発達的変化及び随伴性陰性変動解消過程におけるP300の影響を捉えるため,成人7名と児童8名のCNV解消時問,P300を測定し比較した.そして,P300とCNV解消過程の相関を検討した. その結果,CNV解消時間は,Fzにおいて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).従ってCNV解消過程は発達による影響を受けると考えられる. そして,Fzから導出されたCNV解消時間とCzにおいて導出されたP300の潜時に有意な相関(r=0.613,p<0.05)が認められたことから,CNV解消過程はP300と関係していると考えられる. / The purpose of this study was to investigate the developmental changes in the resolution of contingent negative variation (CNV) and also to examine the effect of P300 for CNV resolution. The CNV resolution times of 7 adults and 8 children were compared. The correlation between the resolution times of CNV and P300 was then calculated. The results showed that the resolution time of CNV at Fz of the adult group was significantly shorter than that of the child group (p<0.01). Therefore, the resolution of CNV may be affected by development. There was a significant correlation between the resolution time of CNV at Fz and the latency of P300 at Cz (r=0.613, p<0.05). Hence, a relationship between the CNV resolution process and P300 is indicated.
