Research and Theoretical Foundations  Theoretical Foundations: Contemporary Research  The evolution of Autism evolved from research about ten years ago when the frequency of ASD was expected to be 1 in 88 children and œnearly 20 years ago, in 2000, it was estimated to be one in 150 children (La Roche, Bush, D™Angelo, 2018, p.108). From the 1970s through the 1980s, estimations were declared to be much lesser then today™s as this indicates that autism arose in œone in several thousand children, leading many to believe that autism was an exceptionally rare childhood disorder (La Roche, et al., 2018, p.108).  The authors state that:  œThe rapid increase in ASD can be at least partially explained through increased public knowledge of ASD, changes in diagnostic criteria, increased visibility of individuals with ASD in the larger community, and the recommendation by the American Academy of Pediatrics that children be universally screened for ASD between the ages of 18 and 24 months (La Roche, et al., 2018, p.108).  Theoretical Foundations: Nature vs. Nurture  Nature is an internal factor that can affect an individual and nurture is an external cause or factor. Autism is a neurodevelopmental disorder and is easy to choose nature because of biological and genetic factors that cause ASD. Most scientists have proved that œgenes are o
