Final answer:
According to the opponent process theory of color vision, if you stare at a small red circle for a minute and then move your eyes to a white surface, a blue circle would appear.
Step-by-step explanation:
According to the opponent process theory of color vision, if you stared at a small red circle for a minute and then moved your eyes to a white surface, a blue circle would appear.
This phenomenon is known as a negative afterimage and provides empirical support for the opponent-process theory of color vision. The theory suggests that when we look at a color for an extended period, the cells in our eyes that respond to that color become fatigued, causing an afterimage in the complementary color.
For example, if we stare at a red object, our red-sensitive cells become fatigued, and when we shift our gaze to a white surface, the fatigued cells respond less, while our green- and blue-sensitive cells continue to fire, resulting in perceiving a blue color.
