ABSTRACT

Long-term memory retrieval ability and working memory can share attention control ability. Based on cognitive plasticity, a hypothesis that cognitive training could improve long-term memory retrieval efficiency and that this could transfer to retrieval involving working memory was proposed. 60 undergraduates were randomly assigned to a group of training and an active control group; all the participants completed the same tasks in the same order before and after the training, the tasks included a long-term memory retrieval access task, a intelligence test, a switching task, a working memory updating task, a response inhibition task and an interference control task. The statistics results indicate that cognitive training can improve long-term memory retrieval efficiency and has a transfer effect on working memory updating, interference control and switching ability, but not on response inhibition or intelligence. This reveal the plasticity of long-term memory retrieval and its influence on working memory.

摘要

长期记忆检索能力和工作记忆可以共享注意力控制能力。基于认知可塑性，提出了一种假设，即认知训练可以提高长期记忆的检索效率，并可以转移到涉及工作记忆的检索中。将60名大学生随机分配到一个训练组和一个主动对照组。所有参与者在训练前后以相同的顺序完成了相同的任务，这些任务包括长期记忆检索访问任务，智力测试，切换任务，工作记忆更新任务，响应抑制任务和干扰控制任务。统计结果表明，认知训练可以提高长期记忆的检索效率，对工作记忆的更新具有转移作用，干扰控制和切换能力，但不能抑制响应或智能。这揭示了长期记忆检索的可塑性及其对工作记忆的影响。
