Two experiments examined children's semantic representations and semantic naming errors. Results suggested that functional and physical properties are core aspects of object representations in the semantic lexicon and that the degree of semantic knowledge makes words more or less vulnerable to retrieval failure. Discussion focuses on the dynamic…

Maintains that the results of Wellman, Cross, and Watson's meta-analysis on the false belief task are perfectly compatible with "early competence" accounts that posit a specific, innate, and possibly modular basis for theory of mind. Asserts that Wellman and colleagues' arguments against such views stem from mistaken assumptions…

Electrophysiology is a timely and important tool in the study of early cognitive development. This commentary polishes the definition of event-related potential (ERP) components; often interpreted as expressions of mental processes. Further, attention is drawn to time-frequency analysis of the electroencephalogram (EEG) which conveys much more…

Based on stimulating findings suggesting that prenatal levels of steroids may influence cognitive functions, a study with N=40 healthy volunteers of both sexes was conducted. Prenatal levels of testosterone (T) were estimated by use of the second-to-fourth digit ratio (2D:4D) which is supposed to be controlled by the same genes involved in…

The capacity to attribute beliefs to others in order to understand action is one of the mainstays of human cognition. Yet it is debatable whether children attribute beliefs in the same way to all agents. In this paper, we present the results of a false-belief task concerning humans and God run with a sample of Maya children aged 4-7, and place…

Two experiments examined the effect of age and cognitive demands on children's choice strategies. Children aged 8-9 and 12-13 years were asked to choose among either two or four products that differed in several attributes of varying importance to them. Choice tasks were designed to differentiate between the lexicographic and the equal-weighting…

The emergence of shared symbol systems is considered to be a pivotal moment in human evolution and human development. These changes are normally explained by reference to changes in people's internal cognitive processes. We present 2 experiments which provide evidence that changes in the external, collaborative processes that people use to…

In this article, the author describes the various changes that are experienced by young adolescents. Physically, early adolescents are growing faster than at any other time in their lives except infancy. They experience significant increases in weight, height, heart size, lung capacity, and muscular strength. Intellectually and cognitively, early…

Advanced inhibitory control skills have been found in bilingual speakers as compared to monolingual controls ( Bialystok, 1999 ). We examined whether this effect is generalized to an unstudied language group (Spanish-English bilingual) and multiple measures of executive function by administering a battery of tasks to 50 kindergarten children drawn…

Schools are a central interface between evolution and culture. They are the contexts in which children learn the evolutionarily novel abilities and knowledge needed to function as adults in modern societies. Evolutionary educational psychology is the study of how an evolved bias in children's learning and motivational systems influences their…

This paper builds on Hatano and Inagaki's pioneering work on the role of experience and cultural models in children's biological reasoning. We use a category-based induction task to consider how experience and cultural models shape rural and urban children's patterns of biological reasoning. We discuss the implications of these findings for…

While the productive role of social interaction between peers in promoting cognitive development has been clearly established, the communicative processes through which this is achieved is less clearly understood. Earlier work has established that different types of conversation become established between children as they work together on a…

This article shares the story of Alex, a gifted child. Alex is clearly gifted when observed through one lens and yet obviously lagging when viewed from a different angle. He knew his letters at 20 months, but did not learn to tie his shoes until the middle of second grade. He taught himself to read just before his third birthday, but in third…

This study examined 4- and 6-year-old children's understanding of the causal relation between the use of a rehearsal strategy and increased recall. In Session 1, children were given two study-recall trials and, on the second trial, were asked to describe their study behavior. In Session 2, children viewed videotaped models and made judgments…

Children's cognitive and perceptual development is explained in Piagetian stage theory.
