Question

Quizplus · Accepted Answer

The visual cliff is a laboratory device for testing depth perception in infants and young animals. It is typically made of clear plexiglass, a tabletop surface of patterned fabric or tiles, topped by a sheet of glass beneath which is a drop-off. Infants are placed on the tabletop surface and enticed to crawl to their mothers, who call to them from either side of the drop-off. Depth perception can be tested in this way because an infant who perceives depth will refuse to venture onto the glass top, while an infant lacking this ability will crawl onto the glass.
