초록
본 연구의 목적은 작업기억 용량과 집행기능의 부하가 목표지향적 걷기 수행에 차이가 있는지 검증하는 것이다. 실험에 참가한 대상은 충남 소재의 대학교에 재학중인 대학생 10명과 지적장애인 2∼3급 10명이었다. 모든 피험자는 목표제시 직후와 목표제시 후에 계산과제 수행후 3, 5, 7m의 목표지점까지 눈감고 걷기의 2가지 과제를 수행하였다. 이들의 목표지향적 이동거리의 오차가 측정되었다. 그 결과 지적 장애가 없는 집단이 장애가 있는 집단에 비해 정확성과 일관성이 모두 우수하였고, 또한 집행기능 부하 조건에서 두 집단 간의 오차의 차이가 더 커졌다. 이 결과가 특수체육 현장에서 어떠한 의미가 있는지에 대해서 논의하였다.
Abstract
The purpose of this study was to verify whether the volume of working memory and the load of executive function has difference on accuracy of targe-directed walking performance. Participants included 10 current students in universities, and 10 individuals with 2∼3 levels of intellectual disabilities who participate life physical education in community welfare center. All participations performed two types of task which was walking performance immediately after identification of target of 3, 5, 7 m distance and walking performance after identification of target and then subtraction calculation within 10 seconds. The error of targe-directed walking distance were observed. As the results, individual without intellectual disability compared with individual with intellectual disability appeared significantly high accuracy and consistency on target-directed locomotion also the difference of error between two groups were more grower in condition with executive function than in condition without executive function load. How to apply this results to the field of adaptation physical education was discussed
