目的:考察情绪刺激加工是否对返回抑制(IOR)效应产生影响。方法:实验一采用经典的线索靶子范式、实验二采用改良的线索靶子范式和事件相关电位技术,要求被试完成情绪辨别任务。结果:实验1发现IOR与情绪效价交互作用不显著;且实验一和实验二都发现,有效线索相比于无效线索在N1上波幅更大,在N170上波幅更小。结论:返回抑制效应没有受到外显情绪加工的影响,表现为返回抑制效应与情绪效应的分离。 Aims: To investigate whether the effects of emotional stimulation processing on return inhibition (IOR) effects. Methods: In experiment 1, the classic cue target paradigm was used. In experiment 2, the improved cue target paradigm and event-related potential technique were used to complete the task of emotion identification. Results: In Experiment 1, it was found that the interaction between IOR and emotional potency was insignificant. In both Experiments 1 and 2, it was found that the effective cues had greater amplitude on N1 and smaller amplitude on N170 than the null cues. Conclusion: The inhibitory effect of return is not affected by explicit emotional processing, which is characterized by the separation of repression effect and emotional effect.
