A new research study has been published as an online preview in The Journal of Autism and Developmental Disorders. In the new study, researchers conducted a 4-minute observation of 18 month old siblings of children with autism and a typically-developing control group. Differences in early functional play were noted among the siblings that eventually received an autism spectrum disorder diagnosis.
Overall, the survey showed that infant siblings of children on the autism spectrum that eventually went on to receive an ASD diagnosis themselves (ASD sibling group) had more repeated play behaviors and fewer functional play behaviors than the typically-developing control group. However, both groups scored similarly in the symbolic play area, which is likely due to their age.
