The present study compared 12 Japanese children with high-functioning autism spectrum disorder (HFASD), ranging in age from 7.3-14.8 years, with 12 typically developing (TD) children matched for age, gender, and vocabulary. The means of full-scale IQ and verbal-IQ of the children with HFASD were 95.92 (SD = 15.30) and 98.00 (SD = 18.44), respectively. Children responded to questions from their mothers in conversations collected under a semi-structured setting, and the responses of both groups were examined from the viewpoint of adequacy. Compared to TD children, HFASD children produced more inadequate responses to Wh-questions than to Yes/No questions. To both types of questions, HFASD children produced more inappropriate responses than TD children. The findings suggest that parents of HFASD children should consider the influence of the question format on these children's response inadequacies.
