초록

"새로운 정보들을 이미 알고 있는 자신의 기억이나 전략 등을 통하여 장기기억으로 저장되기 이전 단계인 단기기억의 과정에서 정보들은 일시적으로 저장된다. 그리고 이러한 인지 과정들을 계획하고 순서를 세우고 실제로 수행을 담당하는 작업장을 작업기억(working memory)이라고 한다(Baddely, 1986; Montgomery, 1995a, 1995b). 작업 기억은 단기기억에 그 기원을 두고 있는 개념이지만, 언어이해 등 처리하는 여러 개의 단기 저장체계의 모델로 확장되었다. 일반적으로 작업기억은 언어성(verbal)과 시-공간적(visual-spatial)영역으로 나뉜다(Geers et al., 2000). 언어성 작업기억은 책 읽기, 독화 자극이 시각적으로 제시되더라도 언어 영역이 담당하여 처리하고, 구어의 음성적, 조음적 특성과 청각을 기초로 하게 된다. 시-공간적 작업기억은 시각적인 정보와 공간적인 정보를 다루며, 시각적 심상을 형성, 유지 및 처리를 한다. 그러므로 언어성 작업기억과 시-공간적 작업기억은 청각과 시각간의 차이로 볼 수 있다(이종민, 2003)."

영어초록

"This study was to examine the relations among working memory, sentence comprehension and recognition performance by children with a cochlear implant. 20 subjects, divided in two groups, participated; 10 normal hearing children and 10 children with a cochlear implant. Children were all between 6 and 8 years old. The duration of implant use for all children with a cochlear implant was between 4 and 6 years. In the working memory task, children recalled words under three different processing load conditions (i.e., no-load, single-load, and dual-load conditions). In the sentence comprehension task, children listened sentences and chose one picture that explained the sentences. In the sentence recognition task, children listened the target sentence and repeated it or wrote it down.
Results of the memory task showed that two groups were not significantly different. However, the children with a cochlear implant showed poorer performance in recalling words in the dual-load condition than those in the other conditions. On the sentence comprehension and recognition tasks, children with a cochlear implant group showed poorer performance than normal hearing children group. In all the three tasks, there were individual variabilities in children with a cochlear implant group. Results of the relationship among three tasks indicated that scores of dual-load condition task were significantly correlated to those of sentence comprehension and recognition tasks in children with a cochlear implant group. Conclusively, findings suggested that children with a cochlear implant have a similar working memory capacity to that of normal hearing children due to early intervention of auditory, speech and language. In addition, findings from children with a cochlear implant group also indicated that their processing capability, especially a complex process, may influence their language ability.
KEY WORDS : Children wearing a cochlear Implant, Sentence comprehension, Sentence recognition, Working memory."
