摘　　要：采用相关分析和结构方程模型的方法考察三种中央执行子功能(刷新、转换和抑制)对创造性问题解决过程中初始表征与搜索阶段以及重构阶段的作用模式。结果发现,抑制功能显著预测初始表征与搜索阶段反应时,刷新与转换功能与重构阶段反应时存在显著相关,但只有刷新功能显著预测重构阶段反应时。本研究结果表明,三种执行子功能在创造性思维的不同阶段发挥作用。Creative thinking is the core of creativity and it is influenced by the executive control function. As basic cognitive processes that control thought and action, executive functions can be divided into three subcomponents: updating, switching and inhibition. Previous behavioral or neuroscience studies have explored the important role of the three subcomponents in creative thinking, but their influence on different cognitive phases in creative thinking has not yet been clarified. Generally, creative thinking starts at the initial representation of problems and searching relevant information in the problem space which usually leads to mental impasse, and the key process of creative thinking is the reconstruction of problem representation. The current study directly separated the creative thinking into these two phases, and used the structural equation model to examine the effect of three subcomponents of executive function on the different processes of creative thinking.Forty undergraduates participated in this study. Short memory task, Stroop task and number-letter task were adopted to measure the subcomponents of executive function, namely the updating, inhibition and switching functions respectively. Participants were asked to first complete the creative thinking task which, in the current study, was to solve the puzzles, and then complete three sub-tasks of the execution function, in which three sub-tasks were presented in random order. Adopting Sandkuhler and Bhattacharya’s(2008) method to directly separate the creative thinking into two phases, namely the initial representation and search phase, and the reconstruction phase. In this paradigm, the subjects were first presented with a puzzle, and then asked to seriously think about the answer within 10 s. Once the subject experienced a mental impasse or mental block(which we described as "you feel that you cannot proceed" or "you just do not know what else to think of") within this initial time period, she/he should press the "enter" key as soon as possible.
