The proposals concerning working memory outlined in this paper involve the architecture of working memory, the reasoning mechanisms that draw on it, and the ways in which working memory may develop with age. Ways of assessing task demands and children's working memory capacities are also considered. It is noted that there is long-standing evidence…

The tasks included: (1) a false-belief task, which tested the…

Children's analogical reasoning has traditionally been measured by classical four-term analogy tasks or problem-solving tasks. Current theories of analogical development and the evidence on which they are based are reviewed. It is concluded that structural views of analogical development are wrong, and knowledge-based accounts of what develops are…

Two naturalistic research studies observed 45 eleventh grade students carrying out research paper assignments, and a third such study focused on 26 third grade students. The studies took place in Alberta (Canada) in 1993, Texas in 1996, and Washington state in 1999. From data analyzed in the interviews and written documents, the initial findings…

This book from the Developing Child series synthesizes recent research examining children's problem-solving skills development. Chapter 1 presents the major themes: (1) there is increasing…
