Comparing sensory processing in children with Down syndrome to a mental age matched sample of children with autism, other developmental disabilities, and typically developing children.

Background: Atypical sensory processing impacts children with intellectual and developmental disabilities (IDD). Research has focused on SP in individuals with autism spectrum disorder (ASD); comparatively, little has been written regarding individuals with Down syndrome (DS) and IDDs.

Aims: We compared patterns of sensory processing in children with DS to children with ASD, other IDDs, and typically developing (TD) peers examining the relationship among different sensory processing measures.
