As an information-bearing auditory attribute of sound, pitch plays a crucial role in the perception of speech and music. Studies examining pitch processing in autism spectrum disorder have produced equivocal results. To understand this discrepancy from a mechanistic perspective, we used a novel data-driven method, the reverse-correlation paradigm,…

Purpose: This study investigated the categorical perception of Mandarin tones and consonant aspiration contrasts in babble noise among adults and adolescents aged 12-14 years, and explored the association between working memory and categorical perception. Method: Twenty-four adults and 20 adolescents with Mandarin as their native language were…

Purpose: Previous studies have shown enhanced pitch and impaired time perception in individuals with autism spectrum disorders (ASD). However, it remains unclear whether such deviated patterns of auditory processing depending on acoustic dimensions would transfer to the higher level linguistic pitch and time processing. In this study, we compared…

Atypical expressive prosody is reported as a consistent challenge for individuals with Autism Spectrum Disorder (ASD) and is associated with a broad set of clinical impairments including perceptions of oddness from others. Theories of atypical prosody in ASD have attributed these impairments to the broader symptoms of ASD, particularly in the…

This paper examined the fundamental frequency variation in the narratives of individuals with high-functioning autism (HFA) and typical controls matched on age, IQ, and verbal abilities. Study 1 found increased fundamental frequency variation in the speech of 21 children and adolescents with HFA when compared to 21 typical controls. Study 2…

This study compared the relationship between acoustic parameters and listeners' perceptions of intonation contours produced by 12 children (ages 7-14) either with severe-to-profound hearing impairments (HI) or normal-hearing (NH). The HI children's productions were generally similar to the NH children in that they used fundamental frequency,…
