The second is the emergence of coordinated representational thought, beginning around 4 years of age. This paper focuses on the second advance, which…

Three hypotheses were tested about how children and adults construct intuitive models when encountering a new property. Causal models showed that 10-, 13-, and 19-year-olds transferred principles from familiar property to novel property. None used default model. Younger children's models were affected by domain. Findings suggest that the transfer…

Examined the development of proportional reasoning by means of a temperature mixture task. Results show the importance of distinguishing between intuitive knowledge and formal computational knowledge of proportional concepts. Provides a new perspective on the relation of intuitive and computational knowledge during development. (GLR)
