Institute on Mental Retardation and Intellectual Development (IMRID)
1964-1995

The Institute on Mental Retardation and Intellectual Development (IMRID) was the Kennedy Center's keystone institute for research on behavioral and biobehavioral aspects of mental retardation and intellectual development. IMRID’s early purpose was to conduct a broad program of research, but its major emphasis was on the retarded intellectual development associated with socioeconomic deprivation. Later, IMRID's research program was directed broadly at learning and its facilitation.

IMRID’s ultimate objective was to understand the nature of learning disabilities associated with mental retardation and then to identify and develop strategies for enhancing the learning and adaptive behavior of persons with intellectual disabilities. A related goal was to contribute to theories and knowledge concerning individual differences in learning, information processing, and human development.

Much of IMRID's research between 1964 and 1973 focused on the behavior and development of persons with mild and moderate mental retardation. From 1973 to its conclusion in 1995, research concerned a broader range of disabilities, including severe and profound mental retardation, and research was carried out in a wider variety of settings. Throughout the evolution of IMRID's research program there was the conviction that learning and its cognitive developmental precursors constitute the major problems in mental retardation that might yield to a behavioral research attack. Consistent emphases on learning and cognitive development and on family and environmental variables were reflected in IMRID's research programs.
