Abstract:
:Poor phonological development adversely affects language development and interpersonal communication abilities in children with Autism Spectrum Disorders (ASD). However, the characteristics of phonological development in children with ASD who speak Putonghua (the official standard spoken form of modern Mandarin Chinese) remain largely unknown. This study aims to investigate phonological acquisition and development among Putonghua-speaking children with ASD. Data were collected from participants recruited in Shanghai, China. Two experiments were conducted. In experiment I, phonological acquisition was compared between 16 children with ASD aged 3-6 years and 16 age-matched typically developing (TD) children. In experiment II, phonological acquisition was compared between 26 children with ASD over 6 years old and 26 receptive-language-age-matched TD children. Picture naming was applied to measure participants' phonology - the 21 initials, 36 finals and four tones of Putonghua. Paired-samples t-tests and Fisher's exact tests were applied. In experiment I, scores on initials, finals, tones and total phonology of children with ASD aged 3-6 years were significantly lower than those of age-matched TD children. The pronunciation accuracy rates for initials such as/x, th, l/, finals such as/jaʊ, joʊ, wo/ and Tone 3 (the low-rising tone) in the ASD group were significantly lower than in the TD group. In experiment II, there was no significant difference in overall phonological developmental level between children with ASD over 6 years old and receptive-language-age-matched TD children. Phonological development of Putonghua-speaking children with ASD was significantly lower than that of age-matched TD children but closer to that of receptive-language-age-matched TD children. Further, participants with ASD showed atypical development sequences in both initials and finals.
