Cross-sectional analysis of cognitive functioning across the life-span
Abstract:
Performance on Piagetian logical concept tasks, standardized intellectual measures, and measures of memory ability, was assessed cross-sectionally. One-hundred-sixty individuals participated. Differential item difficulty patterns were noted on the Piagetian tasks. Curvilinear trends were evident for class inclusion, combinatorial reasoning, and conservation of surface area. Factorial analyses of variance revealed significant chronological age main effects for all tasks except transitivity of weight. Covariance analyses indicated that educational level is generally more closely related to logical concept performance than is chronological age. Dimensional analyses revealed separate factors for general intelligence, classification, relations, and conservation. The youngest and oldest age groups has similar factor patterns; these differed from those of the mature participants.
