Three studies examined whether strategy utilization deficiencies emerge during transfer to two tasks that differ superficially from the main task but have the same underlying structural logic. In Experiment 1, children aged 4, 4 1/2, and 5 spontaneously produced selective attention strategies (or were prompted to do so) on a selective memory task.…

In adults, the ability to apply semantic grouping strategies has been found to depend on working memory. To investigate this relation in children, two sort-recall tasks (one without and one with a grouping instruction) were administered to 6-12-year-olds. The role of working memory was examined by means of mediation analyses and by assessing…

Third, fifth, and seventh graders selected the best strategy (rounding up or rounding down) for estimating answers to two-digit addition problems. Executive function measures were collected for each individual. Data showed that (a) children's skill at both strategy selection and execution improved with age and (b) increased efficiency in executive…

In two studies, we investigated preschoolers' ability to use others' preferences to learn names for things. Two studies demonstrated that preschool children make smart use of others' preferences. In the first study, preschool children only used information about others' preferences when they were clearly linked to referential intentions. The…

Children sometimes solve problems incorrectly because they fail to represent key features of the problems. One potential source of improvements in children's problem representations is learning new problem-solving strategies. Ninety-one 3rd- and 4th-grade students solved mathematical equivalence problems (e.g., 3+4+6=3+__) and completed a…

This article reports findings of the Wurzburg and Gottingen Longitudinal Memory Studies, which focused on children's verbal memory development. The studies started with 102 (German) kindergarten children in Wurzburg and 86 second-graders in Gottingen who were tested on various memory measures, including sort-recall, memory capacity, metamemory,…

Kindergarten, first-, and third-grade children were given a multitrial sort-recall task with different items on each trial. Children were asked to predict how many items they would recall prior to each trial. We classified children into high- and low-overestimation groups based on their prediction accuracy on the first two trials and assessed…

Children's reported use of single and multiple search strategies during a matching numbers task, along with accompanying verbal (private speech, self-talk) and motoric (finger pointing, place-holding) strategic behaviors were examined with a large, nationally representative cross-sectional sample ("n"=1,979) of children between the ages of 5 and…

Presents a computational framework for modeling cognitive development that provides a language paradigm with which to compare and contrast different facets of children's knowledge. Describes the generative connectionist algorithm "cascade-correlation," the successful use of the algorithm to model cognitive development in various…
