摘要
目的:探讨情绪图片和情绪词作用机制的不同。方法:研究使用双选择oddball范式,要求被试通过按不同的键将标准刺激和偏差刺激分类。采用2 (材料:图片和文字) ×3 (情绪:积极,消极,中性)两因素被试内设计,记录其反应时和正确率,对其数据结果进行方差分析。结果:(1) 情绪图片的诱发速度显著快于情绪词;(2) 以汉字作为实验的标准刺激,对偏差刺激的抑制能力高于以图片作为标准刺激的抑制能力,但这是以牺牲反应时为代价的;(3) 中性情绪词的结果与其他刺激显著不同,提示了认知资源分配和加工通道不同的可能性。结论:研究结果从行为层面证明了不同情绪材料的加工涉及不同的作用机制,但两组实验结果的不同提示了加工通道部分重合的可能性,因此,未来有必要使用ERP、核磁等技术对这一问题进行进一步的研究。
Objective: To explore the difference in the mechanism between emotional pictures and emotional words. Methods: This study used a two-choice oddball paradigm that required subjects to classify standard and deviation stimuli by pressing different keys using 2 (material: picture and word) ×3 (emotion: positive, negative, neutral) two factors’ design. The reaction time and correct rate were recorded and analyzed by ANOVA. Results: (1) Emotional pictures are significantly faster than emotional words;(2) When Chinese characters are used as standard test stimuli, the ability to suppress deviant stimuli is stronger than that of using pictures as a standard stimulus, but this result is at the cost of reaction time;(3) The results of neutral emotional words are significantly different from other stimuli, suggesting the possibility of different cognitive resource allocation and pro- cessing channels. Conclusion: The results of the study prove that the processing of different emotional materials involves different mechanisms of action, but the difference between the two sets of experimental results suggests the possibility of partial overlap of the processing channels. Therefore, it is necessary to use ERP, NMR and other technologies to do further research.
