초록
본 연구는 K-WISC-IV 프로파일을 통해 고기능 자폐 스펙트럼 장애(ASD) 아동의 인지적인 특성을 확인하여 고기능 ASD 아동의 진단에 도움을 주며, 임상 및 교육 장면에서 효과적인 개입을 위한 정보를 제공하는데목적이 있다. 이에 6~16세의 고기능 ASD 아동 90명을 대상으로 K-WISC-IV의 전체 IQ, 지표 점수와 소검사 환산점수의 평균을 살펴보았으며, 이와 같은 점수들이 규준 집단과 차이가 있는지 확인하고자 단일 집단 t 검정을 시행하였다. 그 결과 처리속도 지표, 작업기억 지표에서 고기능 ASD아동이 규준 집단에 비해 유의하게 낮은 점수를얻었고, 소검사 수준에서는 이해, 공통그림찾기, 빠진 곳찾기, 순차연결, 산수, 동형찾기, 기호쓰기에서 유의미하게부진한 수행을 보였다. 다시 말해, K-WISC-IV 프로파일을 통해 고기능 ASD 아동들이 처리 속도가 느리고 사회적 판단력이 부족하며 비언어적인 자극을 빠르게 포착하거나 시각 자극의 핵심적 측면을 파악하는 것이 어렵다는특성을 알 수 있었다.
Abstract
The aim of this study is to distinguish children with high-functioning autism spectrum disorder (ASD) from the norm group by identifying their Intelligence with Korean Wechsler Intelligence Scale for Children-Fourth Edition (K-WISC-IV) profile analysis. The article were administered to 90 children with high-functioning ASD (6-16) years and has surveyed the average of the Full scale IQ , index scores, and subtest scores of K-WISC-IV. Also, this study has conducted a single-subject T-test in order to verify whether Full scale IQ, index scores, subtest scores are different from those of the norm group. The results show that children with high-functioning ASD achieved significantly lower scores on Processing Speed Index, compared to the norm group. Furthermore, their scores in Comprehension, Picture Concept, Picture completion, Coding, and Symbol Search were significantly lower than those of the norm group. It is likely that what have turned out to be the cognitive weaknesses of high-functioning ASD children by K-WISC-IV analysis, including slow process speed, low social judgement, and difficulty in visual stimuli in everyday life are interrelated to their unique characters.
