记住部分策略对老年人视觉工作记忆容量的影响

Effects of Remember-subset Strategy on Visual Working Memory Capacity in Old Adults

采用变化检测任务探讨记住部分策略和记住全部策略对青年人和老年人视觉工作记忆容量的影响。结果发现:在老年人中,无论项目数量为3个还是5个,使用记住部分策略的视觉工作记忆表现好于记住全部策略;在青年人中,当项目数量为3个时,记忆策略之间没有显著差异;当项目数量为5个时,使用记住部分策略的视觉工作记忆表现好于记住全部策略。这表明,当超出视觉工作记忆容量时,记住部分策略是提高青年人和老年人视觉工作记忆表现的最佳策略。

The current study used the change detection paradigm to examine the effects of remember-subset strategy and remember-all strategy on visual working memory in the elderly people.The results showed that in the elderly people,regardless of whether the number of items was 3 or 5,compared with remember-all strategy,using remember-subset strategy could significantly increase the capacity of visual working memory.Among the young people,when the number of items was 3,there was no significant difference between remember-all strategy and remember-subset strategy.On the contrary,when the number of items was 5,compared with remember-all strategy,using remember-subset strategy could significantly increase the capacity of visual working memory.This suggests that remember-subset strategy has a positive influence on the young and the old adults when the number of items exceeds its capacity.
