The Visual Evoked Cortical Potential as a Measure of Stress in Naval Environments: (3) The Response to Pattern and Color

Abstract

Previous research has shown that it is possible to isolate a response to pattern from the visual evoked cortical potential. This study investigated the optimum conditions for yielding a pattern response and then applied the pattern response to a test of color vision. The results showed that individuals with normal color vision will give a response to pattern when the pattern is formed of either hue differences or luminance differences. Color defective individuals, however, respond only to luminance differences and not to hue differences that they cannot discriminate. The technique thus can be used as an objective measure of color vision.
