Examines children's understanding of what variables and relations are important in problem structures, and their use of these variables and relations in problem solving. (HOD)

The brain perceives, but its perceptions are conditioned by environment. Traditionally education has reinforced that conditioning; today it must give insight into its arbitrainess and cultural ideosyncrasy. (Author/JH)

Two visual search experiments suggest that: cerebral lateralization of cognitive functions results from differences in sensorimotor resolution capacities of the hemispheres; both hemispheres can process verbal and visuospatial information analytically and holistically; and respective hemispheric competence is a function of the level of…

This study examined the relationship of 28 middle-class Caucasian mothers' attitudes to their intellectually gifted preschool children's perceived competence. Focus was on independence and strictness, maternal concerns, and relationship to support networks (perceived helpfulness of the network, willingness to seek help, and amount of contact the…

Two experiments examined the impact of slow development of processing differences among faces in the spacing among facial features (second-order relations). Computerized tasks involving various face-processing skills were used. Results of experiment with 6-, 8-, and 10-year-olds and with adults indicated that slow development of sensitivity to…

Compares fourth-graders' subtest scores on the Stanford Achievement Test (SAT), the Iowa Test of Basic Skills (ITBS), and the Metropolitan Achievement Test (MAT). Finds right-brain dominant students scored better on four SAT subtests, and left-brain dominant students scored better on four ITBS subtests and two MAT subtests. (NH)

Three experiments examined the exclusivity of perpetually defined categorical representations for animal categories in infants. Results indicated that infants have the capacity for making distinctions among high similar natural kinds but that such find distinctions cannot be made without appropriate exemplars. (SW)

Demonstrates the need for a process-oriented, constructivist approach to understanding infants' categorization abilities. Suggests that emphasizing the distinction between perceptual and conceptual categorization has been an obstacle to forging an approach. Proposes a more microanalytic consideration of features available to infants at different…

Examined degree to which analytic and holistic modes of processing play a role in children's and adults' categorization of faces. Found a developmental trend from analytic to holistic processing and an effect of face inversion with increasing age. Seven-year-olds processed faces comparably to nonfacial visual stimuli, whereas a growing proportion…

This article discusses findings concerning the plasticity of auditory cortical processing mechanisms in adults, including the effects of restricted cochlear damage or behavioral training with acoustic stimuli on the frequency selectivity of auditory cortical neurons and evidence for analogous injury- and use-related plasticity in the adult human…

A bird study found that with sufficient time and training after hair cell and hearing loss and hair cell regeneration, the mature avian auditory system can accommodate input from a newly regenerated periphery sufficiently to allow for recognition of previously familiar vocalizations and the learning of new complex acoustic classifications.…

Trained 1- to 3-year-olds to touch a video screen displaying a unique target and appearing among varying numbers of distracters; correct responses triggered a sound and four animated objects on the screen. Found that children's reaction time patterns resembled those from adults in corresponding search tasks, suggesting that basic perceptual…

This study compiled a comprehensive early auditory processing skills assessment battery and evaluated the battery to toddlers with (n=8) and without (n=9) early recurrent otitis media. The assessment battery successfully distinguished between normal and deficient early auditory processing development in the subjects. The study also found parents…

A word may mean different things in different contexts. The current study explored the changing denotations of spatial terms, focusing on how the distance inferred from a spatial description varied as a function of the size of the objects being spatially related. We examined both terms that explicitly convey distance (i.e., topological terms such…
