Abstract

Children with autism spectrum disorders have persistent deficits in social communication and social interaction, as well as restricted, repetitive patterns of behavior, interests, or activities [1]. The prevalence of autism is estimated at 1-2 per 1000, and close to 6 per 1000 for ASD [23]. ASD is a lifelong disorder, and many individuals need high levels of support throughout their lives [28]. Even though no cure has been found, early intervention is critical for a positive long-term outcome. The interventions that have received the most empirical support are early behavioral interventions. They usually involve one-on-one training provided by a therapist, in which children are trained to respond to environmental changes, understand and use language, and interact appropriately with others in social settings [8].
