Early in the 20th century, many began to voice growing concern over such issues as infant mortality, childhood diseases, and child labor (Anastasiow & Nucci, 1994). At this time, physicians, child advocates, and the general public began to speak out about social concerns regarding children, including those living in orphanages and those with mental illness or intellectual disabilities. These concerns came about at a time when psychologists studying young children began to accept that a child's intelligence was impacted by both genetic and environmental factors (Hunt, 1961). Prior to this point, experts believed a child's IQ was set at birth with little that could be done to influence it over time. Although we were beginning to better understand the importance of environmental influences on young children, at this point, most children with disabilities such as intellectual disabilities, cerebral palsy, and epilepsy were institutionalized rather than treated. On the other hand, children who were deaf or blind were more likely to be treated, but were typically sent away to “schools” and were segregated from their families and peers while receiving treatment and education.
