Question

According to the opponent-process theory, if you stare at a red star for awhile (e.g., 60 seconds) and then look at a plain sheet of white paper you will see an afterimage of the star in which hue?

a. yellow
b. blue
c. green
d. red
e. purple

Answer 1

You will see an afterimage of the star in C. green hue.

Step-by-step explanation:

The Opponent-Process Theory explains that an individual's perception of colors operates under 3 opposing systems:

• Black vs. white
• Red vs. green
• Blue vs. yellow

An individual perceives a hue based on 2 colors but he/she can only see one of these opposing colors at once.

In this case, if you stare at a red star, you are looking at the red vs. green system so once you are done looking at the red, you will see the green afterimage of it, since green opposes red.
