How to Create and Use Binocular Rivalry
Published on: November 10, 2010
Abstract:
Binocular rivalry for a series of colored targets was measured in three trichomats and two red-green dichromats by cumulating those times when ony one target or the other was perceived (exclusive visibility time). Targets were black and colored 3 c/deg square-wave gratings, 1 degree in diameter. For trichromats, exclusive visibility time increased as a function of color difference between the targets, but for dichromats there was no effect of color on binocular rivalry. Taken together, these data indicate that the binocular rivalry mechanism is tritanopic: it is responsive to color signals only from the medium- and long-wave-sensitive cones.
