A visual cliff is a device used to test an infant's depth perception. It consists of a platform that appears to be a flat surface, but in reality has a glass-covered drop-off. This creates the illusion of a cliff, and when an infant is placed on the platform and enticed to come towards the apparent "edge", it can indicate their understanding of depth perception. It is important to note that infants may have a fear response to the visual cliff even if they understand depth perception.
