Final answer:
Depth perception in infancy is primarily developed through binocular vision and monocular cues. Monocular cues, such as overlapping objects and relative size differences, provide depth information within the two-dimensional visual field.
Step-by-step explanation:
Depth perception in infancy is primarily developed through binocular vision and monocular cues. Binocular depth cues compare information represented in the two retinae, as each eye sees the visual field slightly differently. Monocular cues, such as overlapping objects and relative size differences, provide depth information within the two-dimensional visual field.
