In Amblyomaze, what indicates suppression when using the red and green stimuli?

• A. The maze appears steadier.
• B. The light becomes brighter.
• C. The red filter slips off.
• D. The maze or the light disappears.

Answer: (D)

Suppression in this red-green dichoptic setup shows up when the brain excludes input from one eye, so the image from that eye seems to vanish rather than just change in brightness or steadiness. In Amblyomaze, you’re pairing the maze with a light element across the two eyes using different colors. If suppression is occurring, the image presented to the suppressed eye disappears, so the patient reports that the maze or the light disappears. That disappearance is the clearest sign that the input from one eye is being inhibited rather than being fused or enhanced. The other possibilities don’t reflect suppression: a steadier-looking maze suggests consistent perception rather than exclusion; a brighter light implies some level of binocular summation or attention rather than suppression; and a red filter slipping off would be a mechanical issue, not a perceptual indicator of suppression.
