Abstract
DEVRIES, RHETA. Relationships among Piagetian, IQ, and Achievement Assessments. CHILD DEVELOPMENT, 1974, 45, 746-756. Empirical relationships are explored among the theoretically different Piagetian and psychometric assessments of intelligence, and school achievement. Ss were 143 bright and average children chronologically aged 5, 6, and 7 years. Factor analyses of performance on the California Test of Mental Maturity (CTMM), Metropolitan Achievement Test (MAT), Stanford-Binet, and 15 Guttman-scaled Piaget-type tasks indicated that Piagetian, IQ, and achievement tests overlap to some degree, but also measure different aspects of cognitive functioning.
