Abstract
This study clarified the characteristics of using chopsticks among children with autistic spectrum disorder (ASD). The subjects consisted of 18 children with ASD and 16 normally developing children. We evaluated and compared “how to hold chopsticks”, “how to move chopsticks”, and “movement of fingers when using chopsticks”. As a result, the characteristics of how to use chopsticks with a child with ASD included “difficulty in holding chopsticks with thumbs when opening”, “immaturity of separating movements on the radial and ulnar sides”, and “movement of unstable fingers”. Results indicate that relevant factors are the immaturity of separation movement of fingers, vision-based information processing, and executive function disorders.
