本研究将经典情绪启动范式和学习-再认范式相结合,探讨学习时启动与目标的情绪一致性对目标再认的影响。在记忆编码阶段,以情绪面孔图片为启动刺激、一般情绪图片为目标刺激,要求被试对目标图片的效价进行判断;在提取阶段向被试呈现一般情绪图片,要求被试判断是否在前一阶段见过。结果表明,编码阶段的加工背景对记忆提取产生了显著影响。一致启动促进了认知加工与记忆编码,提高了再认正确率。ERP结果也表明,在目标刺激呈现后300-500ms,编码时的情绪一致性对再认阶段消极目标诱发的ERP产生了显著影响。
This study combines the classic emotional initiation paradigm with the learning-re-recognition paradigm to explore the impact of the emotional consistency of initiation and goal learning on target recognition. At the stage of memory coding, the pictures of emotional faces are stimulated. The general emotional picture is the target stimulus, which requires the participants to judge the target picture’s potency. During the extraction stage, the participants are presented with general emotional pictures, asking the participants to judge whether the former A stage seen. The results show that the process of coding stage has a significant impact on memory extraction. Uniform start-up promotes cognitive processing and memory coding and improves the recognition accuracy. The results of ERP also showed that the emotional consistency at the encoding time of 300-500ms after the target stimulus was presented had a significant effect on the negative goal-induced ERP in the re-recognition stage.
