用双任务 (Corsi空间记忆作为第 2任务 )和单 /双回忆的实验范式 ,研究短期记忆编码和提取中的中央系统 (CE)的作用 .实验结果显示 :在提取和编码这两个阶段 ,都出现明显的、由竞争CE资源所引起的数字记忆成绩的下降 .空间记忆负载的增加可能导致CE资源在两任务之间分配的改变 .这与Morris工作记忆和Craik长期记忆的有关实验结果不同 ,其原因可能在于所采用的实验和分析方法的差别
The dual-task (Corsi spatial memory as the second task) and the single / dual memory experimental paradigm are used to study the role of central system (CE) in short-term memory coding and extraction.The experimental results show that in the two stages of extraction and coding, There is a clear decrease of the digital memory performance caused by competing CE resources.Improvement of spatial memory load may lead to the change of allocation of CE resources between the two tasks.This is different from the experimental results of Morris working memory and long-term memory of Craik The reason may lie in the difference between the experimental and analytical methods used
