Depth Perception: Convergence and Retinal Disparity

Very Hard Unit 3: Sensation & Perception Visual System

The visual system processes light in intricate ways to create our perception of the environment. Among the processes involved, the concepts of convergence and retinal disparity are pivotal in understanding how depth perception works. Convergence refers to the inward movement of the eyes as they focus on an object approaching them, while retinal disparity is the slight difference in the images seen by each eye due to their horizontal separation. Given this context, which of the following statements most accurately describes the relationship between these two cues and depth perception?

Convergence is more effective at greater distances where retinal disparity is less pronounced.

Retinal disparity provides depth information primarily for distant objects, whereas convergence is used for nearby objects.

Both convergence and retinal disparity are binocular cues that work together to enhance the perception of depth.

Convergence occurs exclusively in monocular vision, making it less useful for depth perception than retinal disparity.

Retinal disparity can be perceived with one eye, helping to reinforce depth cues that are independently provided by convergence.
