Identifying Young Children with Mild Cognitive Deficiencies

Abstract

Sixty-two 4- and 5-year-old exceptional children, with either mild mental retardation or learning disabilities, were matched on age, sex, and ethnicity with children who were making normal progress. All 62 pairs were presented a minibattery that included 6 cognitive tasks: two memory, three oddity, and a word definition task. The exceptional group performed more poorly than their normal matches on all dependent measures. Discriminant function analyses resulted in classification accuracy levels for the normally achieving group of no less than 89%. Ninety-seven percent of preschoolers with mild mental retardation were correctly identified, as were 84% of children classified as learning disabled. When the two groups with mild cognitive deficiencies were combined, 90% of the children with special educational needs were correctly classified. Cutoff scores applied to frequency distributions were associated with similar levels of accuracy. These results support the contention that a screening test composed of a broad array of cognitive measures should enable more effective identification of young children with mild mental retardation or learning disabilities.
