Which fusion type is associated with depth perception?

• A. Color fusion
• B. Simultaneous perception
• C. Flat/form fusion
• D. Stereopsis

Answer: (D)

Depth perception comes from how the brain uses small differences between the images seen by each eye to sense distance. This ability is called stereopsis, a type of fusion that specifically creates a 3D perception from binocular input. When the two eyes view slightly different images, the brain matches corresponding points and interprets the disparity as depth, giving you a sense of how far objects are. Other fusion types involve different aspects of vision, not depth. Color fusion blends color information from both eyes, simultaneous perception refers to perceiving more than one image at once, and flat/form fusion is about merging outlines to see a flat or 2D form. So the fusion type tied to depth perception is stereopsis.
