Final answer:
The primary limitation of the vertical disparity cue is its potential for ambiguity in distance perception, as it can cause difficulty in accurately judging the distance of objects.
Step-by-step explanation:
One of the limitations of the vertical disparity cue is related to depth perception. Vertical disparity is a type of binocular depth cue, which depends on the slightly different views that each of our eyes has of the world to establish our sense of depth. However, a key limitation here is ambiguity in distance perception. When objects are viewed in isolation or with little contextual information, it can become difficult for the brain to accurately assess the relative distances purely based on vertical disparity. This can lead to a hindrance in accurately judging how far away an object is from the viewer. The other options listed, such as heightened color distortion, reduced peripheral vision, and hindered depth perception, do not specifically relate to vertical disparity.
