언어정보와 시각정보의 통합과정에 관여하는 작동기억 기제 = Working memory mechanism underlying cross-modal association: the verbal and visual information

다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate the working memory mechanism underlying integration of the verbal information with the visual in the multimedia assisted learning. According to Baddeley(2000), the study assumes that the verbal and visual information is separately stored in the two working memory subsystems, phonological loop and visuospatial sketchpad for short time and that the central executive associates the two kinds of information and stores the information concerning the link in the episodic buffer. The study anticipated that when subjects were asked to associate the verbal and visual information performing the secondary tasks to suppress the phonological loop and the visuospatial sketchpad, the performance of the association tasks would not decrease even though the performance of the secondary tasks would decrease. The subjects were 116 fifth and sixth elementary school students. The findings from the study were as follows: There were significant differences in performance of the association tasks and in the performance of the secondary tasks as the suppression level increased. In addition, there were significant differences in the achievement of association tasks when the subjects were asked to associate the newly perceived information with the information recalled from their long term memory. The results of the study partly support Baddeley(2000) except for that the episodic buffer play roles interacting with the phonological loop and the visuospatial sketchpad. The findings suggest that the central executive associates the verbal and visual information and temporarily stores the code about the relationship between the two kinds of information in the episodic buffer even if the verbal and visual information remain in the two working memory subsystems.
