Cognitive tempo in educable mentally retarded children.

The present study investigated the relationship of time and errors on the Matching Familiar Figures test to the mental age of 40 Caucasian male, educable mentally retarded (EMR) children. The children, who ranged in age from six to 18 years, had intelligence test scores of less than 80, were exhibiting problems in adaptive behavior, and were all receiving special education services. An ANOVA revealed that with increasing mental age, elapsed time to first response increased and errors decreased, thus indicating a mental age developmental decrease in impulsivity. For all subjects, time was inversely related to errors. The data suggest that the development of cognitive tempo in EMR children parallels that of nonhandicapped children.
