시공간 작업기억의 분리에 관한 고찰 = A study on the dissociation of visuospatial working memory

다국어 초록 (Multilingual Abstract)

Since Baddeley and Hit ch proposed a model of working memory which is composed of central executive, phonological loop , and visuospatial sketchpad, we have expanded the knowledge about the working memory. The visuospatial sketchpad has gathered less attention than the other two components. However, recent explosion of research about brain has helped the understanding of visuospatial working memory.
This study reviewed the recent research about visuospatial working memory to examine if further dissociation of visuospatial working memory is possible. A lot of research about patients with brain damage has provided the evidences that visual working memory and spatial working memory may be processed separately. This dissociation, however, is not to be understood in terms of hardwired(or structural) separation in brain, because there is a good reason to believe that cognitive process is performed in the way of parallel distributed processing.
The neuropsychological research of visuospatial working memory has also contributed to test the theoretical model of working memory and to investigate the nature of working memory in general. Further research is necessary to examine the development of working memory in terms of general cognitive development.
