And we established a new material which included some sortable indexes to each base logogriph, such as difficulty, accuracy and reaction time. Each pair of riddles included one base logogriph and a target logogriph. A new experimental paradigm was also adopted: a two-stage model for learning-testing, so as to research the time course of successful insight problem solving. Firstly, subjects learned a logogriph (a base logogriph with the answer offered)—learning stage, and then they were asked to solve a homotypical logogriph (a target logogriph, and the base logogriph learned beforehand would provide heuristic information for solving the target logogriph)—testing stage.

在原型激活理论的指导下，本研究通过实验1与实验2初步建立了用于顿悟认知与脑机制研究的字谜材料库，弥补了以往顿悟脑机制研究材料方面的欠缺，主要表现为：首先在材料类型上保证了同质性，都是选用的中国传统文化中的字谜；其次，有足够多的数量，能够满足脑成像研究的多次重复测量和叠加的要求；再次，材料是一一配对的，即每对字谜都由源字谜和靶字谜共同组成，便于研究原型启发效应；最后，提供了多数字谜材料的相关信息，每一个字谜都有正确率、反应时、启发量、巧妙性、难度等分类指标。
