Existing evidence suggests that children, when they first pass standard theory-of-mind tasks, still fail to understand the essential aspectuality of beliefs and other propositional attitudes: such attitudes refer to objects only under specific aspects. Oedipus, for example, believes Yocaste (his mother) is beautiful, but this does not imply that…

D. R. Proffitt and colleagues (e. g., D. R. Proffitt, J. Stefanucci, T. Banton, & W. Epstein, 2003) have suggested that objects appear farther away if more effort is required to act upon them (e.g., by having to throw a ball). The authors attempted to replicate several findings supporting this view but found no effort-related effects in a variety…

Discusses experiments in different school systems in New York and Massachusetts that incorporate Herman T. Epstein's theory of brain development. Many of the programs are aimed at helping teachers identify student cognitive levels and adopt techniques for reaching children at different levels. (WD)

Cognitive acceleration programmes, started in the early 1980s, have now been run in many hundreds of schools in many parts of the world. One important feature of these programmes is that their effects have been evaluated by following up participant students for some years after the intervention. This has provided extensive experience in the…

The mathematical solution to a Piagetian experiment involving topological concepts reported in a recent book is labeled as a sham. The correct solution is given and discussed. (MP)

This article describes how children build increasingly abstract knowledge of linear measurement, emphasizing ways they relate space and number. Assessments indicate children struggle to understand measurement, especially concepts related to complex paths as in perimeter tasks. This article draws on developmental accounts of children's knowledge of…

Presents four educational experiments reflecting Jerome Bruner's theories on iconic and enactive representation to emphasize the need for more research on how children learn. Advocates greater institutional cooperation among schools, teachers, and researchers to improve research implementation and reduce problems of school disruption and…
