摘要：

目的:探讨了情绪状态对汶川震后灾区PTSD儿童有意遗忘能力的影响。方法:依据CCMD-3和DSM-ⅣPTSD诊断标准,选取40名震后PTSD儿童,并随机分配到两种情绪状态下。采用电影片段诱发被试的情绪状态,要求被试依次完成词语学习、算术运算和记忆测试(自由回忆、词语补全和词语再认)三个任务。结果:①积极情绪状态下的词语自由回忆率(0.43)大于消极情绪状态下自由回忆率(0.25);积极词的自由回忆率(0.30)大于消极词的自由回忆率(0.27);指示记忆词语的自由回忆率(0.43)大于指示遗忘词语的自由回忆率(0.15)。②积极情绪状态下(0.44)与消极情绪状态下(0.42)的词语补全率无统计学意义;积极词的补全率(0.48)大于消极词的补全率(0.39);指示记忆词语的补全率(0.48)大于指示遗忘词语的补全率(0.39)。③积极情绪状态下(0.62)与消极情绪状态下(0.59)的词语再认率无统计学意义;积极词的再认率(0.62)大于消极词的再认率(0.57);指示记忆词语的再认率(0.66)大于指示遗忘词语的再认率(0.54)。结论:情绪状态影响PTSD儿童对不同类型情绪词的有意遗忘。积极情绪状态下积极词的有意遗忘效应小于消极词;消极情绪状态下消极词的有意遗忘效应小于积极词。

Objective: To study the influence of emotional state on intentional forgetting of PTSD children.Methods: Forty PTSD children who met with CCMD-3 and DSM-Ⅳ criteria were investigated.Two film episodes were adopted to arouse their positive emotional state or negative emotional state.The PTSD children were asked to perform the words learning,arithmetical operation and words tests(include free recall,words completion and words recognition) in order.Results: ①The free recall accuracy of positive emotional state(0.43) was significantly higher than negative emotional state(0.25).The free recall accuracy of positive words(0.30) was significantly higher than negative words(0.27).The free recall accuracy of to-be-remember words(0.43) was significantly higher than to-be-forget words(0.15).②There was no significant difference of words completion accuracy between positive emotional state(0.44) and negative emotional state(0.42).The words completion accuracy of positive words(0.48) was significantly higher than negative words(0.39).The words completion accuracy of to-be-remember words(0.48) was significantly higher than to-be-forget words(0.39).③ There was no significant difference of words recognition accuracy between positive emotional state(0.62) and negative emotional state(0.59).The words recognition accuracy of positive words(0.62) was significantly higher than negative words(0.57).The words recognition accuracy of to-be-remember words(0.66) was significantly higher than to-be-forget words(0.54).Conclusion: Emotional state influence PTSD children's intentional forgetting effect of emotional words.The intentional forgetting effect of positive words is significantly lower than negative words under positive emotional state,while it's higher than negative words under negative emotional state.
