작업기억과 단기기억의 요구수준이 언어수행력에 미치는 효과

다국어 초록 (Multilingual Abstract)

Purpose: Working memory to evaluate mental resources consists of executive attention, short-term memory, and processing. This study aimed at investigating the relationship between working memory and short-term memory. In particular, the purpose of this study was to examine the effect of working memory and the level of short-term memory in language performance. Methods: Sixty young normal adults participated in this study. They completed a backward digit span as a working memory test and a computerized token test as a language performance test that had two levels of short-term memory. The subjects were divided into two groups (high and low) by their digit span score; the language performance scores and efficiency score from the computerized token test were compared between the high and low working memory groups. Results: The language performance scores and efficiency score of the group with high working memory were significantly higher than that of the low working memory group in three token conditions. However, there were no differences between the two groups in language performance score and efficiency score in two token sentences. Conclusions: The study suggests that short-term memory is also an important component of working memory that can burden mental resources while people process language with their own mental resources in a state of low burden. That is, short-term memory may also consume mental resources that are the restricted fuel for mental processing of human beings. Future studies need to investigated the relationship among the three components of working memory: executive attention, short-term memory, and processing.
