 The purpose of this study is to clarify the characteristics of auditory cognition and understanding of pitch accent in children with autism spectrum disorder (ASD) living in a no-accent area (an area where the pitch accents of homonyms are not differentiated). Previous studies have shown that ASD children have problems with prosody and the understanding of the meaning of words. When they misinterpret homonyms that they hear, it is not clear whether the mistake is due to the dialect or the cognitive characteristics of ASD children, especially when the children live in a no-accent area. A judgment task that asked whether the paired spoken word and picture matched or not was performed by the following 4 groups of subjects:Tokyo-accent adults, no-accent adults, neurotypical children, and ASD children. The conditions used were:matched (correct pitch accent for the picture), mismatched (incorrect pitch accent for the picture), and control. The average number of correct answers for the matched condition was significantly lower for the ASD children group than for the no-accent adult group. It is thought that the performance of children with ASD in this study may be influenced by both the age and the impact of dialect.
