In this study, in order to clarify development of the executive functions of healthy and autistic children, the Dimensional Change Card Sort (DCCS) task was applied to the 3-to 5-year-old healthy children, and the autistic children of 4 to 6 years of chronological age and 3 to 6 years of mental age as well. The useful results were obtained. From the results it was showed that healthy children's executive function progress from age 3 years to 5 years of age, and the development of autistic children's executive function depend on chronological age rather than a mental age. On the other hand, it was observed that some autistic children have difficulty on sorting by color, and there are deviations between some oral answers and actual sorting actions which imply the underdeveloped integration between the actual action and representation. Furthermore. it was found that there is more significant individual difference in score in the autistic children group compared to the healthy one, and this need to be studied further.
