Developmental change emerges from dynamic interactions among networks of neural activity, behavior systems, and experience-dependent processes. A developmental cascades framework captures the sequential, multilevel, cross-domain nature of human development and is ideal for demonstrating how interconnected systems have far-reaching effects in…

Sensorimotor integration is an unconscious process of the brain incorporating multiple senses and movement. This review aimed to synthesize the literature on the role of visual-motor integration in language learning, whether spoken or signed, for deaf and hard of hearing (D/HH) children. Nineteen peer-reviewed studies published between 1980 and…

Perceptual development which depends on ability of learning and maturity, is the most important process of mental development. It is commonly believed that the mental development of children is limited due to city life. Children can learn perceptual elements through movement participation. This improves the cognitive development, which triggers…

How can children's natural perceptuo-motor skills be harnessed for teaching and learning mathematical structure? We address this question in the case of the integers. Existing research suggests that adult mental representations of integers recruit perceptuo-motor functionalities involving symmetry. Building on these findings, we designed a…

Practicing a visual task commonly results in improved performance. Often the improvement does not transfer well to a new retinal location, suggesting that it is mediated by changes occurring in early visual cortex, and indeed neuroimaging and neurophysiological studies both demonstrate that perceptual learning is associated with altered activity…

Previous studies have shown that in comparison with the sighted, blind individuals display superior non-visual perceptual abilities and differ in brain organisation. In this study, we investigated the performance of blind and sighted participants on a vibrotactile discrimination task. Thirty-three blind participants were classified into one of…

A number of asymmetries in lexical memory emerge when monolinguals and early bilinguals are compared to (relatively) late second language (L2) learners. Their study promises to provide insight into the internal processes that both support and ultimately limit L2 learner achievement. Generally, theory building in L2 and bilingual lexical memory has…

The neural mechanisms underlying perceptual learning are still under investigation. Eureka effect is a form of rapid, long-lasting perceptual learning by which a degraded image, which appears meaningless when first seen, becomes recognizable after a single exposure to its undegraded version. We used online interference by focal 10-Hz repetitive…

In this article, the authors introduce a new theoretical framework for understanding intersensory development. Their approach is based upon insights gained from adults who experience synesthesia, in whom sensory stimuli induce extra cross-modal or intramodal percepts. Synesthesia appears to represent one way that typical developmental mechanisms…

Brain Gym[R] (BG; BGI, 2008) is a popular commercial program sold by Brain Gym[R] International (BGI). Making extravagant claims for improved intellectual and physical development, it is used in more than 80 countries. While BGI's claims are persuasive, to date there is little empirical evidence validating the approach. We examine some theoretical…

Within America's school systems, sometime between kindergarten and secondary education, a wide variation appears among the achievement levels of different children. The learning gap between high-achieving high schoolers and dropouts is certainly no secret to educators. Huge sums of federal funds and foundation support have been injected into K-12…

Evidence suggests that visual processing is divided into the dorsal ("how") and ventral ("what") streams. We examined the normal development of these streams and their breakdown under neurological deficit by comparing performance of normally developing children and Williams syndrome individuals on two tasks: a visually guided action ("how") task,…

In normal-hearing children the latency of the P1 component of the cortical evoked response to sound varies as a function of age and, thus, can be used as a biomarker for maturation of central auditory pathways. We assessed P1 latency in 245 congenitally deaf children fit with cochlear implants following various periods of auditory deprivation. If…

In this functional MRI experiment, encoding of objects was associated with activation in left ventrolateral prefrontal/insular and right dorsolateral prefrontal and fusiform regions as well as in the left putamen. By contrast, correct recognition of previously learned objects (R judgments) produced activation in left superior frontal, bilateral…

Split-brain research provides a rationale for the study of media in schools, since media studies provide a vehicle for the development of the right hemisphere of the brain. (Author/ER)
