The Effect of Auditory Sensory Abnormalities on Language Development in Young Children with Autism Spectrum Disorder

Autism Spectrum Disorder (ASD) is a developmental disorder characterized by atypical development in the domains of social, emotional, language and cognitive functioning in the first few years of life. Research indicates an associated phenomenon of sensory processing abnormalities in the ASD population (Baker, Lane, Angley, & Young, 2008), and specifically auditory domain (Tecchio et al., 2003) which may relate to language deficits (Baranek, David, Poe, Stone & Watson, 2006). This study researched the effect of auditory sensory abnormalities on language in young children with ASD (n = 118), specifically receptive and expressive language and prosody. A specific subdomain of auditory abnormalities, sensory seeking, was found to be predictive of expressive language (β = .30, p=.009), perhaps due to a focus on auditory stimuli to the exclusion of expressive language interaction. There was no significant effect for receptive language (β = .16, p=.16) and prosody (β = -.09, p=.493)
