Step 1:Let's solve this step by step:
Step 2:: Understanding the Opponent-Process Theory
The opponent-process theory of color vision, developed by Ewald Hering, proposes that color perception occurs through three opponent channels: - Red-Green channel - Blue-Yellow channel - Black-White (brightness) channel
Step 3:: Analyzing the Characteristics of the Theory
The key feature of this theory is that when one color is viewed intensely, its opponent color is temporarily suppressed, creating an afterimage effect.
Step 4:: Evaluating Each Option
Option A: Color vision weakness at retina periphery - This is related to cone distribution, not the opponent-process theory - NOT explained by this theory Option B: Seeing a different color after staring at a bright color - This directly describes the afterimage effect - When you stare at a red image, you'll see a green afterimage - This is a CLASSIC demonstration of the opponent-process theory - MATCHES the theory perfectly Option C: Recognizing color with tinted glasses - This relates to color constancy - NOT explained by opponent-process theory Option D: Blue dots looking black from a distance - This is about color perception and visual acuity - NOT explained by opponent-process theory
Final Answer
After you stare at a bright color for a minute, you look away and see a different color. The opponent-process theory explains the afterimage phenomenon, where staring at one color creates a temporary perception of its opponent color when looking away.
