Tested the hypothesis that in predicting future behavior of an actor, older children rely on trait inferences, whereas younger children rely on global, evaluative inferences. Found that 9- and 10-year-olds' behavioral predictions were mediated solely by trait ratings, whereas 5- and 6-year-olds' predictions were mediated by evaluative ratings. The…

Two studies addressed whether preschoolers consider speakers' knowledge states when establishing initial word-referent links. Children showed better learning from a speaker knowledgeable of novel words' referents than from an ignorant speaker. Four-year-olds, but not 3-year-olds, learned words better when speaker said the object was made by…

Examined the nature of numerical knowledge in 5-month-olds to inform the debate whether numerical abilities result from capacities dedicated to numerical cognition or to more general perceptual capacities. Found that 5-month-olds could determine the number of collective entities, moving groups of items, when non-numerical perceptual factors such…

Reviews literature on effects of music on the brain in childhood development. Areas include: (1) early synaptic growth; (2) nature versus nurture; (3) background music; (4) musical practice; (5) music learning and cognitive skills; (6) transfer of music learning; (7) musical instrument practice; (8) children and music; and (9) transfer effects.…

Habituated 2-, 5-, and 8-month-olds to visual stimuli following statistically predictable pattern, then showed the familiar pattern alternating with novel sequence of identical stimuli. Found significantly greater interest in novel sequence at all ages. Results support likelihood of domain general statistical learning in infancy and imply that…

The Measure of Epistemological Reflection was revised to reflect a constructivist view of epistemological development that emerged from a longitudinal study of young adults' development. This article includes a description of the new constructivist interpretation process, how it is used, and criteria upon which to judge its value. (Contains 44…

Replies to commentary regarding authors' earlier article proposing a modified constructivist account of origins of mental representation. Elaborates on Smith's discussion contrasting empiricist and constructivist approaches. Discusses Smith's restatement of Piaget's position in terms of levels of representational capacities and replies to specific…

Asserts that this text by Matthews is a remedy to the scant attention paid to philosophical questioning by children. Describes the book's attempt to set children's philosophical questions against a re-examination of children's art and literature, legal issues regarding children's autonomy, and psychological models of the child's cognitive and…

Tested role of event plausibility and script-relevant knowledge in events suggestively planted in memory of 5- to 7-year olds and 9- to 12-year olds. Found that the majority did not remember either false event. Significantly more children recalled the plausible but not the implausible false event; only one recalled the implausible but not…

Counseling reentry dual-career women using a cognitive development framework begins at the individual's level of cognitive functioning and assists in the creation of new cognitive frameworks within the context of sex-role socialization and gender bias. The goal is a new self-concept, awareness of multiple roles, and effective coping skills. (SK)

The learning of eight children (ages 8-13) with Down syndrome was compared with typical children. The control group reached a criterion of learning much faster on a given task. When amount of learning was controlled, children with Down syndrome seemed to have less difficulty in activity-change with the task. (Author/CR)

Examined role of spontaneous gesture in 2- to 4-year-olds' counting and assessment of counting accuracy. Found that correspondence of children's speech and gesture varied systematically across age. Children adhered to one-to-one correspondence principle in gesture prior to speech. Counting accuracy related to correspondence of speech and gesture,…

Two experiments examined preschoolers' performance on test relying on the uniqueness principle for using evidence from a miscount in inferring a counterfactual cardinal number, with subtests probing associated number-skills. All the 5-year-olds and half the preschoolers passed the test. Results suggest that a crucial preschool step is to start…

This study used delayed nonmatching to sample (DNMS) to test the recognition memory function dependent on the medial temporal lobe. Results from three conditions of DNMS tests with 9- and 12-month-olds suggest that the critical late-maturing competence accounting for DNMS success is the ability to understand that the stimulus is a symbol or marker…

Five studies investigated preschoolers' understanding of the biological germ theory of illness compared to that of 6- or 10- to 11-year-olds. Found that the younger the child, the less likely he or she was to judge germs as causes of illness. Studies undermined claim that preschoolers understand germs to be uniquely biological causal agents. (JPB)
