Two experiments are described that investigate the ability to infer the number of items in one-to-one corresponding sets for two age groups. We assess the influence of set size, the visibility of sets, and the way in which set equivalence is derived - pairing versus sharing - using a repeated-measures design. Three-year-olds are largely restricted…

Based on close observations of two 4-year-old children responding to their parents' requests for quantitative comparisons, we offer a "participationist" account of the origins and development of numerical thinking, one that portrays numbers as a product rather than a pregiven object of human communication. In parallel, we propose a…

The domain-independent and domain-dependent approach to the evolution of cognition have been taken by separate groups of researchers who have focused exclusively on either the formal properties or the distinct cognitive demands of tasks. We express the view that synthesizing the two approaches could lead to a more complete understanding, and…

The assumption of domain specificity has been invaluable to the study of the emergence of biological thought in young children. Yet, domains of thought must be understood within a broader context that explains how those domains relate to the surrounding cultures, to different kinds of cognitive constraints, to framing effects, to abilities to…

Predicting how another person will evaluate the intention underlying an action involves consideration of second-order mental states. Children (ages 5-10 years) and college students (N=105) predicted an observer's belief about an actor's intention and evaluated the actor from both their own perspectives and the perspective of the observer. Younger…

The present longitudinal multi-cohort study examines whether interindividual variability in cognitive performance and change increases in old age, and whether associations among developments of different cognitive functions increase with adult age. Multivariate multiple-group latent growth modeling was applied to data from narrow cohorts separated…

Through the years, educational systems in the United States have experienced great change. The one-room schoolhouse is now uncommon, but in years past it was the norm. Changes in society have brought about demands for early care and education systems that were not needed or provided as recently as 100 or even 20 years ago. Families today need and…

Children's thinking is highly variable at every level of analysis, from neural and associative levels to the level of strategies, theories, and other aspects of high-level cognition. This variability exists within people as well as between them; individual children often rely on different strategies or representations on closely related problems…

The marriage of evolution and development to produce the new discipline "evo-devo" in biology is situated in the general history of evolutionary biology, and its significance for developmental cognitive science is discussed. The discovery and description of the highly conserved, robust and "evolvable" mechanisms that organize the vertebrate body…

Neuroconstructivism is a theoretical framework focusing on the construction of representations in the developing brain. Cognitive development is explained as emerging from the experience-dependent development of neural structures supporting mental representations. Neural development occurs in the context of multiple interacting constraints acting…

Individuals with low working memory capacity (e.g. preschoolers) are more prone to goal neglect, or a failure to execute a goal even though it is understood. We examined the role of goal neglect in performance on the Dimensional Change Card Sort by including 'redundant' cards that could be sorted without attending to the rules, as well as the…

In this article, the author analyzes Arthur Efland's "Art and Cognition," which advocates study of the visual arts for its cognitive benefits. The author argues that Efland's cognitive premises are largely sound but that his specific recommendations often belie the general principles he espouses. Efland focuses on the interpretation of baffling…

Both Vygotsky, a psychologist, and Halliday, a social linguist, argue for the central role of language in human development. Language is the principal mode of meaning making; it mediates both the communication through which thinking with others is made possible and also the inner speech through which individual thinking is brought under conscious…

Reminder cues can impact remembering in infancy in multiple ways. Infants typically show highly specific remembering following a reminder, or reactivation procedure, but in some instances, (such as size perception) have demonstrated an ability to remember when given a cue or prime that differs in certain specific characteristics, relative to the…

In recent years, educators have been looking increasingly to neuroscience to inform their understanding of how children's brain and cognitive development are shaped by their learning experiences. However, while this new interdisciplinary approach presents an unprecedented opportunity to explore and debate the educational implications of…
