Although there is a rich literature on children's strategies for remembering, little attention has been paid to characterizing developmental change within individual children and to examining mediators that may bring about such change. To address these issues, we assess children's memory skills over time while simultaneously examining…

One of the lawlike regularities of psychological science is that of developmental progression--an increase in sensorimotor, cognitive, and social functioning from childhood to adulthood. Here, we report a rare violation of this law, a developmental reversal in attention. In Experiment 1, 4­- to 5­- year ­olds (n = 34) and adults (n = 35) performed…

This secondary analysis of data from a randomized control trial of an early mathematics intervention, ROOTS, explored whether patterns of intervention response were best categorized by the typical response/non-response binary or a more complex framework with additional response profiles. Participants included kindergarten students at risk for…

"Patterning" is a cognitive intervention that is unknown to psychologists, but has nevertheless been taught for half a century in nearly all kindergartens and many preschools in English-speaking countries. Patterning is the understanding that a certain rule governs the sequence of items in a series. At the simplest level, if the series…

How do people learn categories and what changes with development? The current study attempts to address these questions by focusing on the role of attention in the development of categorization. In Experiment 1, participants (adults, 7-year-olds, and 4-year-olds) were trained with novel categories consisting of deterministic and probabilistic…

The capacity to plan ahead and provide the means for future ends is an important part of human practical reasoning. When this capacity develops in ontogeny is the matter of an ongoing debate. In this study, 4- and 5-year-olds performed a future planning task in which they had to create the means (a picture of a particular object, e.g., a banana)…

Analogical reasoning is a fundamental cognitive skill of drawing relationships between representations, often between prior knowledge and new representations, that allows for bootstrapping cognitive and language development (Gentner, 2003). Analogical reasoning proficiency develops substantially during childhood, though the mechanisms underlying…

Because math knowledge begins to develop at a young age to varying degrees, it is important to identify foundational cognitive and academic skills that might contribute to its development. The current study focused on two important, but often overlooked skills that recent evidence suggests are important contributors to early math development:…

We investigated the relation between children's numerical-magnitude representations and their memory for numbers. Results of three experiments indicated that the more linear children's magnitude representations were, the more closely their memory of the numbers approximated the numbers presented. This relation was present for preschoolers and…
