How Children with Autism Can Develop Social Skills
Systemic approaches have been found to aid in the development of affect and social skills for children with ASD. One in particular that has been utilized is referred to as the DIR model or the Developmental, Individual Difference, Relationship-Based Model of Intervention developed by Dr. Stanley Greenspan. This program focuses not on discrete behaviours like answering a phone or shaking someone's hand but it uses the child's natural motivation to perform or exhibit a behavior through social interaction and engagement.
