Experiencing a green afterimage of a red object is most easily explained by

A) the opponent-process theory.
B) signal detection theory.
C) the Young-Helmholtz theory.
D) frequency theory.

Green Afterimage

A visual phenomenon where exposure to a green stimulus leads to the perception of a red afterimage when the stimulus is removed, due to the adaptation of photoreceptors.

Opponent-Process Theory

Opponent-Process Theory is a psychological and neurological model that explains how humans perceive colors as the result of complex processes involving opposing responses of color pairs.

Young-Helmholtz Theory

A theory of color vision proposing that the eye perceives colors through the response of three different kinds of cones, each sensitive to red, green, or blue light.
