Over the past 60 years, applied behavior analysis (ABA) has made notable contributions to the literature involving populations with developmental disabilities. Practitioners and researchers have made impressive advances in addressing challenges posed by autism spectrum disorder (ASD), in particular. The focus on autism has resulted in an improved public image of ABA and, in turn, has helped highlight the need for increased awareness surrounding ASD. A summary of relevant research contributions is provided, and although the advances in autism are impressive, individuals with ASD constitute a minority portion of the educational system. A review of the existing literature, as well as a novel literature search, supports the suggestion that ABA has narrowed its focus to issues affecting populations with ASD, while concurrently being less attentive to problems faced by society as a whole, particularly general education.
