We examined the role of early visual input in visual system development by testing adults
who had been born with dense bilateral cataracts that blocked all patterned visual input …

Visual–perceptual, attentional, and visual–motor skills were examined in a group of 16
school-age children, born at 27–32 gestational weeks, who had performed normally on …

Using the method of limits, we measured spatial and temporal vision in 15 patients, aged 4–
28 years, who had been monocularly deprived of patterned visual input during infancy by a …

Psychophysical studies of children deprived of early visual experience by dense cataracts
indicate that there are multiple sensitive periods during which experience can influence …

Shifts of visual attention can be studied in adults and infants by cueing responses to a
particular spatial location. Earlier studies have shown that by seven months of age normal …

Since the 1980s there has been enormous progress in understanding structurefunction links
between visual behaviour and brain systems, but we are still relatively naïve in …

Newborns can see but there are serious limitations on their visual perception. Rapid
improvements occur during infancy, but some aspects of visual perception continue to …

Similarly to sighted people, individuals congenitally affected by a severe visual impairment
can maintain and mentally manipulate spatial information about tactile stimuli [Vecchi, T …

Some crude visual abilities are present at birth, and hence, do not depend on visual
experience. However, there are substantial and rapid postnatal improvements. For example …

To compare the effects of early monocular versus early binocular deprivation on the
perception of global form, we assessed sensitivity to global concentric structure in Glass …
