Understanding Opponent-Process Theory

Medium Unit 3: Sensation & Perception Visual System

The visual system employs several processes to interpret the various wavelengths of light that enter our eyes. One crucial aspect of this system is how color perception occurs. The trichromatic theory of color vision suggests that the retina contains three types of cones that are sensitive to different wavelengths of light. However, there is also an alternative model known as the opponent-process theory, which explains how colors are perceived through opposing pairs. Given this context, which of the following statements best describes the role of the opponent-process theory in visual perception?

It explains how cones in the retina detect red, green, and blue light to create all colors.

It suggests that the perception of color arises from the activity of opposing pairs of colors.

It describes how color perception diminishes with age due to a decrease in cone density.

It indicates that colorblindness is exclusively due to the absence of red cones.

It proposes that color perception is entirely a result of brain processes and not influenced by the eyes.
