Sensory experiences include touch, movement, body awareness, sight, sound, and the pull of gravity. The process of the brain organizing and interpreting this information is called sensory integration. 

Sensory integration provides a crucial foundation for later, more complex learning and behavior. 

Sensory Integration Dysfunction is the inability of the brain to correctly process information brought in by the senses.

Sensory Integration Dysfunction (SID/DSI) or sensory processing deficits can come in many different forms. No two children will be affected in the same ways. SID/DSI was first noticed in children with autism or who have autistic traits. It is also seen in children with other disabilities such as cerebral palsy, ADD/ADHD or can be present by itself.
