The textbook illustrated the production of negative afterimages by suggesting that readers stare at the center of a green heart, edged in yellow. After 20 seconds, when the gaze was switched to a white paper, there was a "change of heart!"
What colors did you "see" in the image of the heart on the white paper? How does opponent-process theory explain this finding?
What will be an ideal response?
Answer: A good answer will include the following key points.
• The heart appeared to be red, edged in blue.
• According to the opponent-process theory, red and green are encoded as antagonistic colors, as are blue and yellow.
• When the yellow and green are removed after staring at them, the cells that were signaling these colors briefly signal the presence of the antagonistic color.
