The visual cliff experiment is a research method used to study depth perception in infants and animals. It involves placing a glass-covered table with a "cliff" edge, creating the illusion of a drop-off, and observing whether subjects avoid stepping off the edge or not.
The Visual Cliff experiment relates to the developmental and cognitive perspectives of psychology, exploring the nature of depth perception and its development in infancy.
Eleanor Gibson and Richard Walk conducted the Visual Cliff experiment in 1960, demonstrating that human infants and young animals can perceive depth by around 6 months of age.
