Which of the following scenarios best illustrates the opponent-process theory of color vision?

note is played.
A

Conrad can identify specific features in his environment, such as color.
B

Kayla sees afterimages of opposing colors when she stares at a poster for a long time.
C

Randy is able to process many aspects of a visual scene simultaneously.
D

Russell is able to differentiate between dark green and light green.

Kayla sees afterimages of opposing colors when she stares at a poster for a long time.

Explanation:

The "opponent-process theory" is a theory developed by Edward Hering. It states that three color pairs, which are opposing in nature, are linked by the cone receptors. These pairs are:

This can be done when you stare at an afterimage patch for 30 seconds. Such as what Kayla is doing. Once the color stimuli is removed and she fixates her attention to a dot at the center of her field, she'll notice the colors being reversed. This means that if she sees the original color as "blue," she'll see it now as "yellow" and vice-versa.

Extended inspection of a color in a pair results to it being fatigued. This allows the non-fatigued color pair to be noticed.

So, this explains the answer.
