초록

Purpose of this study is to develop a computer-based working memory test tool for children based on Baddeley's 3 component model and also investigate its validity. For this reason, we developed a working memory test battery of 8 subtasks, which measures 3 components of working memory(phonological loop, visuospatial sketchpad and central executive), from January to December 2017. A total of 120 normal kindergartens and elementary school students in Seoul and the Capital area, were administered our working memory test battery. The results of the validation analysis of collected data are as follows. First, there was a significant positive correlation among all working memory subtasks. In particular, there was a relatively high level of correlation between subtasks corresponding to each working memory component. Second, inter-item consistency revealed through Cronbach’s alpha showed that reliability of working memory subtasks was higher than .7. Third, confirmatory factor analysis showed a good fit between Baddeley’s model and the test tool data, as the subtasks had strong loadings on appropriate factors of corresponding working memory elements. Finally, good criterion-related validity was shown through the correlation between the working memory test and fluid intelligence test. This suggests that our working memory test is valid to some extent in regard to criteria of fluid intelligence. This study is significant in that it has developed a test tool, that collectively measures each element of working memory based on theoretical background.
