Visual half-field development in children: Detection of colour-contrast-defined forms
Recently we have shown that children's ability to perceive motion-defined forms shows an asymmetry in the left and right visual half-fields which disappears in adulthood. The present study is focused on the visual half-field development of colour contrast vision in the same group of subjects. It was found that colour contrast thresholds for the detection of colour-contrast-defined forms decreas...
متن کاملVisual half-field development in children: detection of motion-defined forms
It is widely accepted that the maturation of the extrastriate cortex is not completed before late puberty. To gain insight into the functionality of the extrastriate cortex during normal development, we tested a group of 21 children (age 6-16 years) on their ability to detect motion-defined forms. With a two-alternative forced-choice procedures we determined thresholds and visual half-field asy...
متن کاملContrast normalization in colour vision: the effect of luminance contrast on colour contrast detection
While contrast normalization is well known to occur in luminance vision between overlaid achromatic contrasts, and in colour vision between overlaid colour contrasts, it is unknown whether it transfers between colour and luminance contrast. Here we investigate whether contrast detection in colour vision can be normalized by achromatic contrast, or whether this is a selective process driven only...
متن کاملRemodelling colour contrast: implications for visual processing and colour representation
Colour contrast describes the influence of one colour on the perception of colours in neighbouring areas. This study addresses two issues: (i) the accurate representation of the colour changes; (ii) the underlying visual mechanisms. Observers viewed a haploscopic display in which a standard display was presented to one eye and a matching display to the other. The matches could be represented ac...
متن کاملDevelopment of Visual Acuity and Contrast Sensitivity in Children
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 visual function becomes truly adult-like. Yet from a clinical and research perspective it is important to know this. This review paper is a discussion of the development of visual acuity and contrast sensitivity into ...
