RT Journal Article SR Electronic T1 Cross-cultural Piagetian Research: An Experimental Perspective JF Harvard Educational Review JO herp FD Harvard Educational Press SP 475 OP 506 DO 10.17763/haer.45.4.kpq1578t13tk0541 VO 45 IS 4 A1 Ashton, Patricia Teague YR 1975 UL http://harvardeducationalreview.org/content/45/4/475.abstract AB Over the last twenty-five years children around the world have observed and responded to researchers who pour water from beaker to beaker, roll plasticene into snake-like figures, and arrange matchsticks into a potpourri of shapes. These cross-cultural experiments have been undertaken to test Piaget's theory of genetic epistemology, which posits a hierarchical, universal, and invariant sequence of stages of cognitive development. Piagetian research in varying cultures has revealed both striking similarities and marked differences in performance on cognitive tasks, some in apparent conflict with the basic assumptions of Piagetian stage theory. In this article Professor Ashton reviews a range of cross-cultural Piagetian research, analyzes the sometimes divergent findings from this research, and suggests methodological improvements which may help to resolve past dilemmas and to further future understanding of cognitive growth in different cultures.
