权力概念隐喻映射中的冲突控制:特征与过程

Metaphorical Conflict Control in the Conceptual Mapping of Social Power: Processing Characteristic and Stages

本研究采用ERP技术探讨了权力概念的隐喻冲突机制。实验基于空间Stroop任务变式,使用身份词对作为刺激,操作词对间的字体大小和左右位置,检验权力的大小隐喻和左右隐喻与其概念表征存在冲突时的认知加工过程。行为结果发现,词对的字体大小与位置左右共同影响了权力概念判断,呈现隐喻冲突的基本特点。ERP结果显示隐喻冲突连续体现在早期N1、N2pc成分,以及晚期N400、NSW和LPC成分上。结果表明,权力的概念判断可同时受到大小隐喻和左右隐喻的影响。因隐喻知觉线索与概念表征失匹配而引发的隐喻冲突,不仅会出现在早期注意阶段,也会出现在晚期的语义编码和评估阶段。

This study explored the cognitive mechanisms of the metaphorical conflict control in the conceptual representation of social power using event-related potentials.In the present study,a spatial Stroop task was employed,and word-pairs of social statuses were utilized as stimuli.Through manipulating the relative font sizes of the word-pairs and their spatial positions,the time-course of the metaphorical conflicts among the font sizes,spatial positions,and the social power concepts were examined.Behavioral results revealed typical characteristics of metaphorical conflicts,in which the social power judgment on word-pairs was significantly affected by font sizes,spatial positions,and their interactions.Moreover,ERP results showed that metaphorical conflict processing was continually manifested in early N1 and N2pc components,as well as N400,NSW and LPC components.Our study showed that the semantic representation of social power was simultaneously affected by metaphors of font size and spatial position.Additionally,the metaphorical conflict caused by the conflict between perceptual clues and conceptual representation arose not only at the early perceptual processing stage but also at the later semantic evaluation stage.
