Creativity consists of divergent and convergent thinking, with both related to individual eye blinks at rest. To assess underlying mechanisms between eye blinks and traditional creativity tasks, we investigated the relationship between creativity performance and eye blinks at rest and during tasks. Participants performed an alternative uses and remote association task while eye blinks were recorded. Results showed that the relationship between eye blinks at rest and creativity performance was compatible with those of previous research. Interestingly, we found that the generation of ideas increased as a function of eye blink number during the alternative uses task. On the other hand, during the remote association task, accuracy was independent of eye blink number during the task, but response time increased with it. Moreover, eye blink changes in participants who responded quickly during the remote association task were different depending on their resting state eye blinks; that is, participants with many eye blinks during rest showed little increasing eye blinks and achieved solutions quickly. Positive correlations between eye blinks during creative tasks and yielding ideas on the alternative uses task and response time on the remote association task suggest that eye blinks during creativity tasks relate to divergent thinking processes such as conceptual reorganization.
创造力由发散性思维和聚合性思维组成，这两者都与个体静息时的眨眼有关。为了评估眨眼与传统创造力任务之间的潜在机制，我们研究了创造力表现与静息时以及任务过程中的眨眼之间的关系。参与者在进行替代用途任务和远距离联想任务时，同时记录他们的眨眼情况。结果表明，静息时的眨眼与创造力表现之间的关系与先前研究一致。有趣的是，我们发现在替代用途任务中，想法的产生随着眨眼次数的增加而增加。另一方面，在远距离联想任务中，任务期间的准确性与眨眼次数无关，但反应时间随眨眼次数增加。此外，在远距离联想任务中反应迅速的参与者，其眨眼变化因静息时的眨眼情况而异；也就是说，静息时眨眼次数多的参与者，任务期间眨眼增加很少且能快速得出答案。创造性任务中的眨眼与替代用途任务中产生想法以及远距离联想任务中的反应时间之间的正相关表明，创造性任务中的眨眼与概念重组等发散性思维过程有关。
