As a nurse and mother of a son diagnosed with autism, Barbera (lead behavior analyst, Pennsylvania Verbal Behavior Project) explains an approach to skills' building and behavior change that parents of minimally vocal children can often carry out without professional help. She explains how the Verbal Behavior Approach builds on, and differs from, Lovaas' applied behavior analysis. The book includes sign language examples, sample skills tracking sheets, and resources.
