ABA applied in Autism Spectrum Disorder

I need a report about how ABA is used in children and or adults with Autism Spectrum Disorder.
First I need to describe ASD, Autism Spectrum Disorde, then describe ABA and the different methods and then explain how it is applied.

I will submit a sample outline as soon as I get home.

Koegel is a reference she would like us to use along with any UCSB autism center source.
