Abstract

|
Joint attention is associated with early social and language development. The purpose of this study was to compare joint attention behaviors of toddlers who are at risk of Autism Spectrum Disorders(ASD) and developmental language delay(DLD) to those of typically developing(TD) toddlers. The participants were 15 toddlers with at risk for ASD, 15 with DLD, and 15 TD toddlers matched on chronological age. The toddlers’ behavior samples were elicited through CSBS DP procedures and total frequency of joint attention, initiating of joint attention(IJA) and responding to joint attention(RJA) behaviors were measured. The results as followed: The at-risk ASD group showed significantly fewer total joint attention and RJA behaviors than DLD and TD groups. And the at-risk ASD toddlers showed significantly fewer IJA than only TD group. The results suggest that joint attention behavior could be considered as an early symptom that differentiate toddlers at-risk for ASD from toddlers with DLD as well as typically developing toddlers.
