Quick Summary

The visual cliff is a research technology used to study depth perception in infants and young animals. It consists of a platform with a transparent surface, creating the illusion of a steep drop-off. Typically, subjects placed on the platform show reluctance to step onto the "deep" side, indicating an innate ability to perceive depth and avoid potential harm.1

Research using the visual cliff has demonstrated that even visually naive subjects exhibit depth perception, suggesting it is not solely learned but has innate components. While early visual experience is crucial for maintaining and elaborating perceptual abilities, basic functions like pattern and depth perception appear to be present from birth.1
