Direct linkHornburg, Caroline Byrd; Wang, Lijuan; McNeil, Nicole M. – Child Development, 2018
A prevailing theory of mathematical problem solving predicts that children will be less accurate solving a + b = c + __ problems versus a + b = __ + c. However, this has never been tested directly. Because of low base rates, information combined from multiple studies can help improve estimation accuracy and precision. This study compared…

Peer reviewedMeehan, Anita M. – Child Development, 1984
Examines the findings of 53 studies of sex differences in propositional logic, combinatorial reasoning, and proportional reasoning tasks. Finds sex differences for the latter two tasks to be vulnerable to Rosenthal's "file drawer" problem and effect size to be small for all tasks. Discusses possible explanations for sex differences in…
