【摘要】：对概念扩展神经机制的探讨日益成为创造性认知"过程式"研究视角下的热点。但以往研究未能排除评估效应对实验的影响,亦未考察过人格因素与任务态下神经活动的关系。实验向被试随机呈现高低扩展两类的报纸用途,要求被试认真思考"合理的操作方式",使报纸能够实现呈现的用途。同时对其进行f NIRS的兴趣区扫描,并在事后要求被试完成大五人格量表。结果发现,与低扩展条件相比,高扩展条件会引起颞叶区域(BA21/22)更大的激活,而额极(BA10)和背外侧前额皮层(BA9)的激活会显著降低;人格元特质可塑性与额极和眶额皮层的活动正相关。提示概念扩展过程中,可能需要颞叶脑区激活与前额脑区去激活的协同作用,且该过程与人格因素存在相关关系。
[Abstract]:The exploration of conceptual extension neural mechanism has increasingly become a hot topic in the perspective of creative cognition. However, previous studies have not ruled out the effect of evaluation on the experiment, nor have they examined the relationship between personality factors and neural activity in the task state. The experiment expands the use of two kinds of newspapers to the random presentation of the subjects, and requires the subjects to think carefully about the "reasonable operation mode" so that the newspaper can realize the purpose of presentation. At the same time, the F NIRS region of interest was scanned and the subjects were asked to complete the Big five Personality scale. The results showed that the activation of temporal lobe area (BA21 / 22) was significantly lower in the frontal pole (BA10) and dorsolateral prefrontal cortex (BA9) than in the low expansion condition. Personality meta-trait plasticity is positively correlated with frontal pole and orbital frontal cortex activity. It is suggested that the activation of temporal lobe and the deactivation of prefrontal area may be required in the process of conceptual expansion, and this process is related to personality factors.
