Sensory reinforcement and contingency awareness of profoundly retarded children. 1978

J Haskett, and W D Hollar

In two experiments, three of four profoundly retarded and physically handicapped children with MAs below 7 months demonstrated instrumental learning of a manipulatory response that produced either illumination or music. Discrimination of response-dependent from response-independent stimulation was demonstrated by the three subjects. Further, changes in two categories of collateral behavior, vacalizing and smiling, seemed to reflect recognition of changes in stimulus conditions. Results indicated that profoundly retarded children share with normally developing infants and children the capacity to be reinforced by sensory stimulation and to discriminate contingent from noncontingent events.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D008607	Intellectual Disability	Subnormal intellectual functioning which originates during the developmental period. This has multiple potential etiologies, including genetic defects and perinatal insults. Intelligence quotient (IQ) scores are commonly used to determine whether an individual has an intellectual disability. IQ scores between 70 and 79 are in the borderline range. Scores below 67 are in the disabled range.
