Normal and Defective Colour Vision
Amblyopia has been attributed to a shift in sensitivity of the visual system toward low spatial-frequency filter mechanisms. This chapter analyzes the capacity to recognize moving signals and how colour can help in this task. It shows that changes in

By applying the color-naming psychophysical method and a Wright colorimeter, a chromatic sequence produced by the mixture of different quantities of red-green and blue-yellow is described. Retinal mixtures are produced monocularly in the classical ma

18 cases of Glaucoma, 20 of Retinal diseases, 15 of Optical nerve diseases and 15 of Ambloyopia, were studied. The results of both tests are analyzed for statistical significance, and the possibility of using the tests for diagnostic differentiation

The red-green chromatic and temporal fusion time required by normal and color-deficient observers was compared by means of red-green chromatic pulses of constant luminosity. The data obtained demonstrate the possibility of a new temporal test of acqu

A study is reported of twelve chromatic functions and one achromatic function of brightness, and fourteen chromatic functions and one achromatic function of lightness with the aim of establishing the change in the exponent of the functions, a phenome

Working with colours generated from the three primaries, we found earlier that blue made it difficult to obtain dichoptic mixtures, producing chromatostereopsis and alternation effects which disappeared with increasing eccentricity (1 deg 3 min) or d

Magnitude estimations of saturation were obtained for each of 15 pigmented surfaces of different hue, viewed under artificial light in a 4° test field. Saturation was found to be related to colorimetric purity by a power function whose exponent vari

A total of 63 psychophysical lightness functions and 28 saturation functions of surface colors and grays were measured for 40 observers by the method of magnitude estimation. Although there is some variation in the size of the exponent from one perso

The present study investigated (a) the correlations between different periodical and aperiodical contrast tests as applied to glaucoma, and (b) their performance with reference to the conventional visual acuity and perimetry tests.

The method of magnitude estimation was used to analyze chromatic edge detection produced by isoluminant stimuli. Observers quantified the visibility of edges produced by six different pairs of hues at variable saturation. When the data were plotted o
