With respect to the trichromatic and the opponent-process theories of color perception, which of the following statements is most likely to be true?

Question

Quizplus · Accepted Answer

The trichromatic theory suggests that color vision is based on the presence of three types of cones in the retina that are sensitive to blue, green, and red wavelengths, whereas the opponent-process theory proposes that color vision is based on neural mechanisms that process information from cones in an opponent manner (e.g., red vs. green, blue vs. yellow). Both theories have some empirical support, but it is generally accepted that trichromatic processing occurs within the retina, whereas opponent mechanisms operate both within the retina and at later stages of neuronal processing in the brain. Thus, statement C is most likely to be true.
