中文摘要:

当前的学习比较了更新的进程口头并且 visuospatial 工作存储器(WM ) 并且在更新任务的工作存储器检验了中央行政官和奴隶系统的角色,由变化,项目的数字同时更新了在中央行政官上操作负担。实验 1 使用了更新任务的口头的 WM,并且结果验证了范例的效率在中央行政官上操作负担。实验 2 采用了更新任务的口头的 WM,与防碍音韵学上的环的分节的抑制任务。结果由莫利斯舞和琼斯支持了学习,表明中央行政系统起了在口头的 WM 的更新的部件的一个重要作用,当音韵学上的环为连续召回部件负责时。实验 3 采用了更新任务的 visuospatial WM,与防碍 visuospatial 大意垫的空间拍任务。结果建议 visuospatial 一起勾略垫和中央行政官处理了更新的部件,当 visuospatial 大意垫为由自己的连续召回部件负责时。这些结果与 visuospatial 大意垫近有的调查结果一致与中央行政官一起连接,当音韵学上的环与中央行政官被分开时。它建议那更新的 visuospatial 和口头的 WM 不是二个平行过程。

英文摘要:

The current study compared the processes of updating verbal and visuospatial working memory (WM) and examined the roles of central executive and slave systems in working memory updating tasks, by changing the number of items updated simultaneously to manipulate the load on central executive. Experiment 1 used the verbal WM updating task, and the results validated the efficiency of the paradigm to manipulate the load on central executive. Experiment 2 employed the verbal WM updating task, with the articulatory suppression task to interfere with the phonological loop. The results supported the study by Morris and Jones, revealing that the central executive system played an important role in the updating component of verbal WM, while the phonological loop was responsible for the serial recall component. Experiment 3 employed the visuospatial WM updating task, with the spatial tapping task to interfere with the visuospatial sketchpad. The results suggested that the visuospatial sketchpad and the central executive together dealt with the updating component, while the visuospatial sketchpad was responsible for the serial recall component by itself. These results are consistent with the findings that visuospatial sketchpad has close links with central executive, while the phonological loop is separated from the central executive. It suggests that updating visuospatial and verbal WM are not two parallel processes.
