摘　　要：目的:探究急性运动是否可作为一种干预手段作用于大学生负性情绪信息的有意遗忘,以及情绪材料的性质和时间耦合对这一过程的影响。方法:将102名大学本科女生随机分为编码前运动组、编码后运动组和对照组,以10 min中等强度持续运动为运动干预方式,采用项目法有意遗忘范式,以低唤醒负性词、高唤醒负性词和中性词为记忆材料,比较不同组别被试在自由回忆正确数、再认的辨别力指数d’及相对应的有意遗忘效应值上的差异。结果:编码前运动组在再认任务中的有意遗忘效应值显著高于对照组,主要体现在编码前运动组忘记指令词语d’显著低于对照组,编码后运动组的自由回忆正确数呈现出低于编码前运动组和对照组的趋势。结论:编码前运动通过提升个体对信息的抑制控制能力促进有意遗忘的执行,编码后运动则通过干扰记忆巩固过程降低整体回忆表现。提示急性运动可提升个体主动抑制负性情绪信息记忆编码的能力,而在经历负性情绪事件后进行的急性运动能够帮助个体更快遗忘相关负性信息。Objective:To explore whether acute exercise can act as an intervention in the directed forgetting of negative emotional information in college students,and then to investigate the influence of emotional materials and temporal coupling on this process.Methods:A total of 102 female college students were randomly divided into before-encoding exercise group,after-encoding exercise group and control group.The intervention protocol was 10-minute moderate intensity continuous exercise.Based on the item method of directed forgetting paradigm,the low arousal negative words,high arousal negative words,and neutral words were used as memory materials.The number of correct free recall,the discrimination index d’,and the corresponding directed forgetting values were compared.Results:The DF value of the before-encoding exercise group in the recognition task was significantly higher than that of the control group,mainly reflected in the significantly lower d’of the before-encoding exercise group under the forget instruction.The corrected free recall number of after-encoding exercise group was lower than that of the before-encoding exercise group and the control group.Conclusions:Before-encoding exercise promote the directed forgetting by improving the suppression ability of forget instruction information,and after-encoding exercise reduces the memory performance indiscriminate by interfering the memory consolidation process.It is suggested that acute exercise can enhance individual’s ability in suppressing memory encoding of negative emotional information,and acute exercise can also help individuals to forget negative information quickly after experiencing negative emotional events.
