摘要
在创造性问题解决研究中,目前主要存在两种理论争论,即表征转换理论与进
程监控理论之争。本文在进一步细化实验材料的基础上,通过三个实验系统地考察
了在左右视野呈现条件下,不同意识水平呈现线索(两字阈上呈现、一字阈下呈现
和两字阈下呈现)、不同类型线索(紧密线索和重合线索)以及不同的启动条件(正
启动和负启动)对两类谜语问题解决的影响。具体结论如下:()反扣谜语难于正
扣谜语,原因在于两者需要松懈的约束数目不同;()线索效应在不平衡意识条件
下的左右大脑协同之间没有差异,而在阈下协同与不平衡意识协同条件之间存在显
著差异;()紧密与重合两类语义线索与其呈现的意识水平之间存在交互作用,不
平衡意识条件呈现条件下,重合线索的促进作用要大于紧密线索;()负启动条件
下,两类谜语的成绩都相对地显著高于正启动条件下的成绩。实验结果支持表征转
换理论。

Abstract
The mainly arguments of the creativity problem solving are from two theories that
are representational change theory and progress monitoring theory. Based on the
developed experimental material, four factors were explored to understand the mechanism
of the influence of two kinds of riddles, which are the hemisphere present (left and right),
the awareness of clue displaying (both of characters upon threshold, one of them under
threshold, and both under threshold), the type of clue (meaning fastened and overlapped),
and priming condition (positive priming, negative, and non-priming). The brief conclusion
would be introduced in ing section. Firstly, the reason why reversed riddle is more
difficult than ordinary ones is probably the numbers of constraint relaxation are differ;
secondly, no difference of clue effect is existed between the two kinds of unbalanced
hemispheres cooperation condition, instead, which have dissimilar performances with the
hemispheres cooperation at the under awareness level; thirdly, one significant interaction
effect was found between two kinds of clue, meaning fastened and overlapped, and
awareness condition of presentation; forthly, the performance of these two kinds riddle in
the negative prime situation is much higher than the positive prime condition with
prominent statistical meaning. The results of these three experiments support the
representational chang
