摘　　要：运用ERP技术对个体猜谜任务下的顿悟和无顿悟的情况进行探索。结果发现,在300ms-500ms内,有顿悟比无顿悟引发了更负的N300-500成分,激活了大部分脑区;在600ms-1100ms内,有顿悟比无顿悟引发了更正的P600-1100成分,在中央区显示了最强激活。结果表明,N300-500可能反映了定势破除中的认知冲突,P600-1100可能反映了新异联系的形成。The electrophysiologicaI correlates of insight and non-insight problems solving were studied using event-re- lated potentials （ERPs） when participates guessed the Chinese logogriphs. Results showed that insight elicited a more negative ERP deflection （N300-500） than non-insight between 300 and 500 ms in most of the brain scalp regions. Subsequently, insight elicited a more positive ERP deflection （P600-1100） than non-insight in the time window of 600 and 1100 ms, maps of P600-1100 showed strong activity mostly in the central scalp region. The results indicated that the N300-500 might reflect cognition conflict in the breaking of mental set and the P600- 1100 might play important roles in the forming of novel associations.
