Final answer:
The experiments with the visual cliff suggest that depth perception is partly innate.
Step-by-step explanation:
The experiments with the visual cliff suggest that depth perception is partly innate. The visual cliff experiment is used to test an infant's depth perception. It consists of a table with a transparent surface that creates the illusion of a drop-off. When infants are placed on the table, they typically show signs of fear or hesitation when they perceive the drop-off, indicating that they have depth perception. This suggests that depth perception is not learned but rather is a natural ability that develops early in infancy.
