A) The physiological support for the trichromatic theory is greater than the support for the opponent-process theory.
B) The physiological evidence for the opponent-process theory has shown that the trichromatic theory is incorrect.
C) The psychophysical evidence for the trichromatic theory has shown that the opponent-process theory is incorrect.
D) The physiology of the cone receptors and the discovery of opponent cells in the retina and LGN show that both theories are correct.

Question

Quizplus · Accepted Answer

The physiology of the cone receptors and the discovery of opponent cells in the retina and LGN show that both theories (trichromatic and opponent-process) are correct. While the trichromatic theory explains how the photoreceptor cells in the eye respond to different wavelengths of light, the opponent-process theory explains how signals from these photoreceptor cells are processed in the visual system. Both theories are supported by physiological and psychophysical evidence. Therefore, the current consensus is that both theories are necessary to fully understand color vision.
