Chromatic: Chromatic Thresholds across the Life Span
Description
Thresholds for equiluminant chromatic differences as a function of age along 3 axes in the CIE xy chromaticiy diagram. Data were obtained using a spatial, two-alternative forced-choice paradigm. Responses were obtained from preverbal observers using forced-choice preferential looking.
Usage

Arguments
Details
Equiluminant modulations along the Protan and Deutan axes projected in the CIE xy-plane are not cone-isolating. However, in the experiment, the chromatic modulations were presented mixed with dynamic, random luminance noise that had been shown to mask luminance components of the stimulus, thus favoring detection by chromatic pathways.
