Outline of Final Research Achievements |
Autistic spectrum disorder (ASD) is a developmental disorder characterized by persistent difficulties in social interaction and communication as well as restricted patterns of interests and behaviors (American Psychological Association: APA, 2013). Atypicality is manifested in speech processing in children with ASD, which may be associated with language-related impairment. The current study investigated speech perception in children with ASD. The results of the present study suggest that speech perception in children with ASD is not as attuned to their native language as in their TD peers. Our findings also indicate that language delay or impairment is related to difficulty in perception of native phonemes in children with ASD.

Academic Significance and Societal Importance of the Research Achievements |
自閉スペクトラム症(Autism Spectrum Disorder,ASD)は「社会的コミュニケーションおよび対人的相互反応における持続的な欠陥」と「行動、興味、または活動の限定された反復的様式」の2つの特徴をもつ神経発達症である。言語コミュニケーションにおいては主に語用論の側面に問題が生じることが指摘されてきたが、言語の構造的側面における特徴についてはこれまで十分に検討されてこなかった。本研究により、音韻、統語、語彙にも問題を抱えるASD児が多いことが明らかになった意義は大きく、今後の研究で、語用に加え、言語の構造的な面からの検討が重要であることが示唆された。
