In monocular suppression within a binocular field, which eye should perceive the central target?

• A. The non-suppressing eye
• B. The eye that is occluded
• C. The eye that is suppressing
• D. Either eye

Answer: (C)

Monocular suppression is when the brain dampens input from one eye so that a single, fused image can be seen when both eyes are open but alignment or signals conflict. In a central target test within a binocular field, the percept you report is the one coming from the eye that is suppressing. The suppressed eye’s image at the center remains the signal that reaches awareness under suppression, whereas the other eye’s central input is inhibited to avoid rivalry. If the central target were seen by the non-suppressing eye, that would imply no suppression at that location. The occluded eye cannot see the target, and saying either eye would ignore which eye is currently suppressed. So the central target is best perceived by the eye that is suppressing.
