Exploring the nature of joint attention impairments in young children with autism spectrum disorder: associated social and cognitive skills.

It is generally accepted that joint attention skills are impaired in children with autism spectrum disorder (ASD). In this study, social preference, attention disengagement and intention understanding, assumed to be associated with the development of joint attention, are explored in relation to joint attention skills in children with ASD at the age of 36 months. Response to joint attention was related to intention understanding, whereas the number of joint attention initiations was associated with attention disengagement, and somewhat less stronger with social preference. The level on which children initiated joint attention was related to social preference. Possible interpretations of these findings are discussed.
