visual cliff

The visual cliff is a scientific experiment designed to study whether young children and animals can perceive depth and feel cautious around edges. It involves a glass-covered surface with a pattern underneath that creates the illusion of a drop-off or cliff. When infants or animals are encouraged to cross, they often hesitate or refuse at the "ledge," indicating an ability to perceive depth cues and understand potential danger. This experiment helps researchers understand the development of visual perception and innate cautiousness related to avoiding falls or threats in their environment.
