Autism instance of pervasive developmental disorder
DSM-III and pervasive developmental disorder (1980–1987)
The DSM-III (1980) redefined the childhood type of schizophrenia as three kinds of "pervasive developmental disorder" (PDD). "Infantile autism" began before a child was 30 months old, and "childhood onset pervasive developmental disorder" began between 30 months and 12 years. A third variety, "Atypical pervasive developmental disorder" was similar but lesser than the other two, and could begin at any time.Lorna Wing's February 1981 publication of a series of case studies (Asperger's Syndrome: A Clinical Account), greatly increased awareness of the existence of normal and high IQ people with autistic traits by clinicians. She also greatly increased awareness of Hans Asperger's work.
Norwegian-American psychologist Ivar Lovaas completed the "UCLA Young Autism Project" in 1987, defining a new method of ABA. It is sometimes called the "Lovaas method/model/program" and sometimes the "UCLA model/intervention". It has become the primary form of Early Intensive Behavior Intervention (EIBI), and now is often referred to by that name as well.
