The severe amblyopia induced by chronic monocular deprivation is highly resistant to reversal in adulthood. Here we use a rodent model to show that recovery from deprivation amblyopia can be achieved in adults by a two-step sequence, involving enhancement of synaptic plasticity in the visual cortex by dark exposure followed immediately by visual…

The aim of the present study was to compare the types of exploratory procedures employed by children when exploring bidimensional tactile patterns and correlate the use of these procedures with the children's shape drawing performance. 18 early blind children, 20 children with low vision and 24 age-matched blindfolded sighted children aged…

Infants with visual impairment often require additional interaction from adults to reinforce behaviors that lead to competency at mealtimes, but parental and professional confidence in teaching these skills is often limited. In the following collective case study, the authors, a speech/language pathologist (S/LP), occupational therapist (OT), and…

Dr. Orfield's highly readable guide on vision development presents ground-breaking solutions to common learning problems and is supported by substantial data. This holistic common sense--that most people do not know--is not just about vision but also how vision is interrelated with learning. It teaches how to care for a child's vision as well as…

When entering the Blind Childrens Center (BCC), what a person might not realize is that four of the five visually impaired children in a classroom share the same diagnosis of Optic Nerve Hypoplasia (OHN). ONH is the leading cause of blindness and visual impairment in young children. It is important that these children participate in an inclusive…

Four experiments investigated how readily infants achieve perceptual organization by lightness and form similarity. Infants were (a) familiarized with elements that could be organized into rows or columns on the basis of lightness or form similarity and tested with vertical versus horizontal bars depicting the familiar versus novel organization or…
