学习时的情绪图片背景对词语再认记忆的影响：SOA和背景呈现时间的调节作用 Recognition Memory of Words Can Be Impaired by Task-Irrelevant Emotional Encoding Contexts: The Moderating Effect of SOA and Context Duration

本研究采用学习—再认范式，考察编码阶段与任务无关的图片背景的情绪唤醒程度、呈现时长、以及背景与目标词语呈现的时间间隔等对词语再认记忆的影响，探讨情绪背景对词语记忆的损害作用发生的条件。在学习阶段，单词叠加呈现在背景图片中央，只要求被试记忆单词。测验阶段，词语单独呈现，要求被试做新旧判断。结果发现，相对于中性背景，情绪背景损害了词语的再认。且情绪背景对词语再认的损害效应受到背景呈现时间的影响。 The present study attempted to investigate the influences of emotional arousal, stimulus onset asynchrony (SOA) of context and target, context duration of task-irrelevant picture and context on recognition memory of words using study-test paradigm. During study, words were superimposed centrally onto emotional contexts, and subjects were asked to just remember the words. During test, both studied and new words were presented without the emotional contexts and subjects had to make “old/new” judgments for those words. We found that, compared with the neutral context, the emotional context impaired recognition of words. And the impairing effect of the emotional contexts was influenced by the context duration.
