字谜问题解决中的策略调用

The Activation and Adoption of Strategies in Solving Character Riddle Problem

以分解、组合和组分3种策略的字谜问题为实验材料,采用事件相关电位技术探讨字谜问题解决中3种策略调用过程的脑内时程动态变化,结果发现：谜面出现后的300~500 ms和600~800 ms两个时段内,3种策略产生不同程度的分离,其中300~500 ms时间段可能反应了调的过程,600~800 ms时间段可能反应了用的过程.这似乎表明策略调用可能存在两个阶段的认知加工过程.

There are three kinds of riddles used as experimental material,of them the rules are different.By the technology of event-related potentials（ERP）,the character of strategies in riddle problem-solving is analyzed.At last it is found： Within the two stages of 300-500 ms and 600-800 ms,the ERPs of the three strategies are different.It seems that 300-500 ms reflects the process of the activation of strategies and 600-800 ms reflects the process of adoption.That means the Activation and Adoption of Strategies is a two-stage cognitive process.
