title: Scalogram And Factor Analyses Of Two Tests Of Cognitive Development.
abstract: Two tests of cognitive development, the Cartoon Conservation Scales (CCS), Levels I and II, were designed to measure Piagetian stage-related constructs for children of different age groups (De Avila, 1976). The tests were factor analyzed within age level and were also analyzed using scalogram and tabular methods to test sequential hypotheses. The appropriateness of these two methodological approaches to the analysis of developmental data was discussed and results were compared. It was noted that factor differentiation appears to be related to Wohlwill's (1973) concept of divergent horizontal decalage, or increasing lag in the mastery of construct pairs which are theoretically germane to the same level of cognitive functioning.
