| 摘 要： | 运用事件相关电位ERPs技术, 采用猜谜任务范式, 从字谜问题解决中谜底“催化”所诱发顿悟的时间进程和半球差异两方面来探讨顿悟的认知神经机制。结果发现：在320~550ms内, “有顿悟”和“不理解”较“无顿悟”的ERP波形均有一个更大的负向偏移。在“有顿悟-无顿悟”和“不理解-无顿悟”差异波中, 该负成分的潜伏期约为380ms, 差异波的脑电峰值锁定在Cz点。半球主效应不显著, 但反应与半球交互效应显著, 其中“有顿悟”差异波的右半球平均波幅显著高于左半球和矢中部。结果表明：N380可能反映了顿悟中舍弃强外显意义而选择弱内在隐喻意义的认知抉择过程, 且右半球在“顿悟”中表现出优势效应。

| Abstract: | Cognitive insight phenomenon is one of the components of creativity which lies at the core of numerous discoveries.Our developed high spatial resolution brain imaging(e.g.functional magnetic resonance imaging) and excellent temporal resolution event related potentials techniques have made it possible to explore the brain mechanism and neural basis of insight problem solving.Nowadays,neurocognitive mechanism of insight embedded an Aha experience is a hot studying but still mystery topic.The present study tri... |
