The effects of the number of Hangul syllable, the nunber/location of batchim in a Hangul word, and compound/noncompound Hangul word on memory span were examined. The results were that (1) the more syllables a word had, the lower us memory span was, (2) the more batchims a two-syllable word had, the lower its memory span was (Korean batchim effect on memory span), (3) noncompound word had higher memory span than compound word. The reading speed of above mentioned words was measured and the results were that (1) the more syllables a word had, the slower its reading speed was, (2) but the reading speed of a two-syllable word was forest when it had a batchim on second syllable than when it had no batchim or had a batchim on first syllable or batchims on both syllables (Korean ending batchim effect on reading speed), (3) noncompound word was read faster thu compound word. Korean ending batchim effect on reading speed was not compatible with the explanation by articulatory loop bur compatible with the explanation by visual cache where the orthographic information was represented. The results suggest that memory span was influenced nor only by phonological information but also by orthographic information.

도구추론에서 읽기범위에 따른 개인차 효과가 나타나는지를 살펴보고자 2개의 실험을 수행하였다. 실험 1에서 어휘판단과제를 사용한 결과 읽기범위가 큰 이해자는 도구추론을 온라인으로 생성하였지만, 읽기범위가 작은 이해자는 도구추론을 온라인으로 생성하지 못하는 것으로 나타났다. 그림명명과제를 사용한 실험 2 에서는 읽기 범위에 관계없이 도구추론이 온라인으로 생성되는 것으로 나타났다. 실험 1과 2의 상반된 결과를 종합해 보면, 언어이해과정에서는 발생하는 도구추론의 유형은 언어적인 도구추론과 시각적인 도구추론으로 구분할 수 있으며, 어휘판단과제는 언어적 추론에 민감한 과제인 반면, 그림명명과제는 시각적 추론에 매우 민감함 과제인 것으로 해석할 수 있다. 이러한 결과는 읽기범위가 작업기억의 음운루프 모듈에서의 처리효율성을 반영하는 측정치라는 점을 시사한다.

The purpose of this study was to examine the working memory that is related with reading. For this purpose, the third and fourth grade children with reading difficulty were compared with normal children. The gender comparison and the correlations among the three components of working memory were also examined. The results indicated that the reading difficulty group were outperformed by the normal group in every test. Gender difference was found only in visuospatial capacity. There was an interaction between reading and gender in the memory of dynamic mazes. In the whole group, every correlation among all components was significant. When the correlations were examined separately in each group, however, only one correlation was significant in both groups. When the influence of the central executive was controlled, the interrelationship between phonological working memory and visuospatial working memory was mitigated. This study suggests that when teaching children with reading difficulty instructional material should be succinct and visuospatial information needs to be used for boys if possible.
