【摘要】：情绪启动效应是近几十年来研究的热点领域，并且许多研究证实了情绪启动效应的存在。Fazio最早应用实验研究并提出了情绪启动效应，当个体在接触到一些具有情绪性的刺激后，会对后面的相应的刺激蒙上一层感情色彩。近年来，研究者发现了情绪启动的反转效应，即目标词的与启动词的情绪效价相反时反应更快的现象。已有的研究大多要求被试对目标词的情绪效价做出判断，在这种任务范式下，启动词与目标词的情绪效价是否一致决定了启动词和目标的反应倾向是否相同。本研究对比了不同任务形式下的汉字情绪启动效应，以进一步检验情绪启动效应的认知机制和时间进程问题，对反应倾向的竞争模型进行检验。实验一采用字-字情绪启动范式，任务为情绪效价判断。选取20名大学生作为被试，采用3（启动字情绪价：积极、中性、消极）×2（目标字情绪价：积极、消极）×2（目标字的频率：高频、低频）三因素完全被试内设计。结果发现，高频目标字出现情绪启动的反转效应，低频目标字出现情绪启动的一致性效应。主要表现在反应时的变化以及早期注意成分P200，N400和晚期正成分LPC的差异。实验二使用真假字判断任务，，对比任务形式的变化对情绪启动效应的影响。选取20名大学生作为被试，采用2（启动字情绪价：积极、消极）×2（目标字情绪价：积极、消极）×2（目标字的频率：高频、低频）三因素完全被试内设计。结果发现，无论是高频目标字还是低频目标字均出现情绪启动的一致性效应。主要表现在反应时以及N400和LPC成分的差异上。综合两个实验的结果证实了情绪启动的反转效应来自于特定的任务形式，反转效应和一致性效应可以用反应竞争模型来解释。
[Abstract]:Emotional priming effect is a hot research field in recent decades, and many studies have confirmed the existence of emotional priming effect. Fazio first applied experimental research and proposed emotional priming effect, when an individual is exposed to some emotional stimuli, Will be behind the corresponding stimulus coated with a layer of emotional color. In recent years, researchers have discovered the reverse effect of emotional priming, that is, when the emotional titer of the target word is opposite to that of the promoter word, the most of the previous studies have asked the subjects to make a judgment on the emotional titer of the target word. In this task paradigm, whether the emotional potency of the initiator and the target word is the same or not determines whether the response tendency of the primer word and the target word is the same or not. The present study compares the emotional priming effects of Chinese characters in different task forms. In order to further test the cognitive mechanism and time process of emotional priming effect, the competitive model of reaction tendency is tested. In experiment 1, we adopted the "word-character emotion priming" paradigm, and the task was to judge the emotion titer. Twenty college students were selected as subjects, and 3 (priming word emotion price: positive, neutral, negative) 脳 2 (target word emotion price: positive), Negative) 脳 2 (the frequency of target words: high frequency, low frequency) was completely designed in the subjects. The results showed that the high frequency target words had the reverse effect of emotional priming. The low frequency target words have the consistent effect of emotional priming mainly in the change of reaction time and the difference between the early attention component P200 N400 and the late positive component LPC. Experiment 2 used true and false word to judge the task, and compared the influence of the change of task form on emotional priming effect. Twenty college students were selected as subjects, and 2 (priming word emotion price: positive, negative) 脳 2 (target word emotion price: positive), experiment 2 (target word emotion price: positive), experiment 2 (target word emotion price: positive), Negative) 脳 2 (target word frequency: high frequency, low frequency) three factors were completely designed in the subjects. Whether high frequency target word or low frequency target word, there is a consistent effect of emotional priming, mainly in reaction time and the difference between N400 and LPC components. The results of two experiments show that the reversal effect of emotional priming comes from a specific task form, and the reverse effect and consistency effect can be explained by the reactive competition model.
