目的:考察不同情绪转换条件下,个体在前摄干扰的建立、最大化和释放阶段的工作记忆成绩。方法:对35名小学生施测前摄干扰任务,对比不同情绪条件下,儿童在前摄干扰各阶段的回忆正确率。结果:前摄干扰阶段的主效应显著(P 0.05)。结论:前摄干扰的释放有利于工作记忆成绩。相比高愉悦情绪词,低愉悦情绪词显著地降低了儿童的工作记忆成绩。 Objective: The aim of the present study is to explore proactive interference (PI) in the process of working memory in different emotional conditions, and to explore whether there is the existence of proactive interference release in the emotional shifts. Methods: 35 children in primary school were administered to perform proactive interference task. We compared the working memory scores in different emotional conditions. Results: It is significant for the main effect of PI (P < 0.05), and the correct frequency of PI release is significant higher than that of PI building. The main effect of emotion type is significant (P < 0.01), and the correct frequency of positive words is higher than that of negative words. It is not significant interaction between PI and emotion type. Conclusion: The release of PI can increase the working memory performance. There are more bad working memory performance in the low-happy emotional words than that of high-happy emotional words.
