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

Leber congenital amaurosis (LCA) is a rare hereditary retinal degeneration caused by
mutations in more than a dozen genes. RPE65, one of these mutated genes, is highly …

Using 20 levels of intensity, we measured children's thresholds to discriminate the six basic
emotional expressions from neutral and their misidentification rates. Combined with the …

Most previous studies investigating children's ability to recognize facial expressions used
only intense exemplars. Here we compared the sensitivity of 5-, 7-, and 10-year-olds with …

Two relevant dimensions are revealed within which developmental patterns of perceptual
organization might be investigated. Within the local–integrative dimension, employing a …

The ability to distinguish contrast plays an important role in patients' everyday vision.
Contrast sensitivity testing can identify many ocular diseases. Testing the peak of contrast …

PURPOSE: Most studies of visual development have concentrated on visual development of
infants. Only a few studies have extended this to children and determined the point at which …

The main aim of this review is to evaluate the proposal that several developmental disorders
affecting vision share an impairment of the dorsal visual stream. First, the current definitions …

The effects of early-onset blindness on the development of the visual system have been
explained traditionally by the stabilization of transient connections through Hebbian …

Despite the emerging scientific and clinical importance of measuring human contrast
sensitivity (CS), developmental data are sparse, especially those obtained with a single …
