The Development and Validation of a Test Battery Measuring Specific Cognitive Abilities in Four-Year-Old Children

Abstract
A battery of nine specific cognitive abilities tests to assess verbal, spatial, perceptual speed, and memory abilities in children at age 4 was constructed and administered to a sample of 267 children participating in the Colorado Adoption Project. Exploratory and confirmatory factor analyses revealed four correlated factors that adequately describe the covariation among the tests. Specific cognitive ability composites showed test-retest correlations ranging from .56 to .81. The reliable measurement of these specific cognitive abilities in preschool children facilitates analyses of familial resemblance and longitudinal comparisons.
