Which type of visual perception requires the use of both eyes?

1. Monocular cues

2. Binocular cues

3. Peripheral vision

4. Depth perception without binocular vision

The correct answer is: Binocular cues

Binocular cues are essential for certain aspects of visual perception, particularly depth perception, which relies on the slightly different views each eye has of an object. The brain combines these two images to help determine the distance and depth of an object in relation to the viewer. This process, known as binocular disparity, is a key element in creating a three-dimensional understanding of the environment. Monocular cues, on the other hand, can be perceived using just one eye and include elements such as relative size, texture gradient, and linear perspective. Peripheral vision refers to the ability to see objects outside of one's direct line of sight, which is also based primarily on monocular cues. Depth perception without binocular vision refers to techniques or cues used to perceive depth without relying on the input from both eyes, which further emphasizes the importance of binocular cues for depth perception in typical visual processing.
