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)

Used data from National Longitudinal Survey of Youth to model developmental trajectories across middle childhood. Found that individual trajectories were extremely diverse in level and sometimes in slope. Compared to girls, boys had heterogeneous slopes for math and behavior problems. Compared to boys, girls showed a significantly higher degree of…

Examined preschoolers' and second and fifth graders' development of two types of perspective taking: (1) perspective taking based on differences in the information available to two people; and (2) perspective taking based on differences in weighting the same information. (RH)
