What monocular depth cue is based on the size of the retinal image, with larger images perceived as closer?

The correct answer is based on the concept of relative size, which refers to the perception of objects based on the size of their retinal images. When two objects are known to be of similar size, the one that appears larger on the retina is interpreted as being closer to the viewer. This cue plays a crucial role in depth perception, as it helps individuals determine the spatial relationship between objects in a three-dimensional environment.

In contrast, pictorial cues refer to a range of cues used in two-dimensional images to create an impression of depth and do not focus solely on the size of objects. Interposition involves the idea that if one object overlaps another, the overlapping object is perceived as being closer, instead of relying on the actual size of the objects. Linear perspective is a phenomenon where parallel lines appear to converge in the distance, providing another depth cue, but again, it does not specifically pertain to the size of the retinal images. Understanding these concepts helps clarify how we interpret the distances and sizes of objects in our environment.
