Question

Quizplus · Accepted Answer

The opponent-process theory explains the phenomenon of afterimages, which occur when we continue to perceive an image even after it is removed. The theory proposes that cells in the visual system respond to colors in pairs, with one cell responding to red and inhibiting its opposite cell, which responds to green. Similarly, one cell responds to blue and inhibits its opposite cell, which responds to yellow. When we stare at an image for a prolonged period, these cells become fatigued, and when we look away, the opposite cells are activated, causing an afterimage of the complementary colors.
