【摘要】：采用词汇flanker任务分析认知和情绪冲突及其冲突适应效应。结果发现,在认知和情绪flanker任务中,相对于目标词与干扰词一致的情况,被试在目标词和干扰词不一致的情况下反应更慢,正确率更低。这表明认知词和情绪词flanker任务都能诱发冲突效应。本研究还发现认知冲突适应效应的存在,但没有发现情绪冲突适应效应,该结果可能与刺激材料的复杂性和范式选取有关。此外,研究还发现,相对于目标刺激是金属的认知词和积极的情绪词,被试对目标刺激是水果的认知词和消极的情绪词反应更快。特别是在目标词与干扰词不一致的情况下,被试对水果词和消极词判断的正确率要显著高于对金属词和积极词的判断。未来的研究需要在刺激和范式的修正上进一步探索,并加强情绪冲突与认知冲突适应效应的关系及其影响因素、神经机制的研究。
[Abstract]:Lexical flanker task was used to analyze cognitive and emotional conflicts and their conflict adaptation effects. The results showed that in the cognitive and emotional flanker tasks, the subjects' response was slower and the accuracy rate was lower when the target words were not consistent with the distraction words compared with the target words and the distraction words. This suggests that both cognitive and emotional flanker tasks can induce conflict effects. This study also found the existence of cognitive conflict adaptation effect, but not emotional conflict adaptation effect, which may be related to the complexity of stimulus materials and paradigm selection. In addition, the study also found that the subjects responded more quickly to the target stimuli being fruit cognitive words and negative emotional words than the target stimuli were metal cognitive words and positive emotional words. Especially when the target word and the interfering word were inconsistent, the correct rate of judgment of fruit word and negative word was significantly higher than that of metal word and positive word. The future research needs to further explore the stimulus and paradigm revision, and strengthen the relationship between emotional conflict and cognitive conflict adaptation effect and its influencing factors, neural mechanism.
