Abstract
Standardization data collected for the Goldschmid-Bentler conservation scales were analyzed for evidence of continuity or discontinuity in growth of conservation skills. At younger and older age groupings the resulting total score distributions were strongly unimodal, indicative of nonconservation and conservation, respectively. In age groupings containing extremes of nonconservers as well as conservers, children's scores were not obviously trimodal as a 3-stage hypothesis would predict. The score distributions appeared continuous but were clearly not normal in nature.Keywords
