ABSTRACT

The present study aimed to explore the neural-related mechanism of the creative evaluation process in individual with different levels of creativity. The time course of evaluation process for creative objects was monitored by event-related potentials (EPRs). Forty-five participants were divided into the high-creativity performance (HCP) group and the low-creativity performance (LCP) group and then completed a creative object evaluation task. The behavioral results revealed that the HCP group showed higher accuracy rates on the creative object evaluation task than the LCP group did. The ERPs analysis demonstrated that in the early stage of creative object processing, ordinary objects elicited a more negative anterior N2 at 190–340 ms than the creative objects did in the LCP group. In the late stage of creative object processing, creative objects elicited a more positive ERPs deflection in the HCP group than in the LCP group at 350–500 ms and at 500–1000 ms. Taken together, these results indicate that different creativity performance individuals may express different attention patterns or top-down processing strategy in the early stage of creative object evaluation processing; and high-creativity performance individuals can better utilize both cognitive and non-cognitive evaluation processing in the late stage, to process the creative object effectively.

摘要

本研究旨在探讨具有不同创造力水平的个人的创造力评估过程的神经相关机制。通过与事件相关的电位（EPR）监控创意对象评估过程的时间过程。将45名参与者分为高创造力表现（HCP）组和低创造力表现（LCP）组，然后完成创造力对象评估任务。行为结果表明，与LCP组相比，HCP组在创意对象评估任务上显示出更高的准确率。ERPs分析表明，在创意对象处理的早期阶段，普通对象在190-340 ms处比LCP组的创意对象产生更负的前N2。在创意对象处理的后期，在350-500毫秒和500-1000毫秒时，创意对象在HCP组中引起的ERP偏转比LCP组中更积极。综上所述，这些结果表明，不同的创造力表现个体在创意对象评估处理的早期阶段可能会表现出不同的注意力模式或自上而下的处理策略。并且具有高创造力的个人可以在后期更好地利用认知和非认知评估过程，以有效地处理创意对象。这些结果表明，不同的创造力表现个体在创意对象评估处理的早期阶段可能会表达不同的注意力模式或自上而下的处理策略。并且具有高创造力的个人可以在后期更好地利用认知和非认知评估过程，以有效地处理创意对象。这些结果表明，不同的创造力表现个体在创意对象评估处理的早期阶段可能会表达不同的注意力模式或自上而下的处理策略。并且具有高创造力的个人可以在后期更好地利用认知和非认知评估过程，以有效地处理创意对象。
