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…

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…

Discusses a study of the neurophysiological effects of television viewing and their impact on learning. Study of brain waves while viewing indicates that the brain switches off from any analytical processing of the messages. (JMF)

An outstanding gain in their ability to visualize and create inventive and imaginative drawings after having been challenged by sensory activities indicates children's abilities to develop and use the right sides of their brains. (Author/SEW)
