To test this, they placed 36 infants, six to fourteen months of age, on the shallow side of the visual cliff apparatus. Once the infant was placed on the opaque end of the platform, the caregiver (typically a parent) stood on the other side of the transparent plexiglas, calling out for them to come or holding an enticing stimulus such as a toy.
This test consisted of a table, half coated in a checkerboard pattern, and the other half a clear plexiglass sheet, revealing a second checkerboard platform about a foot below. Although the plexiglass was safe to climb on, the infants refused to cross over due to the perception of a visual cliff.

Gibson emphasized the importance of environment and context in learning and, together with husband and fellow psychologist James J. Gibson, argued that perception was crucial as it allowed humans to adapt to their environments.
One of the important discoveries of infant depth perception is thanks to researchers Eleanor J. Gibson and R.D. Walk. [18] Gibson and Walk developed an apparatus called the visual cliff that could be used to investigate visual depth perception in infants. In short, infants were placed on a centerboard to one side which contained an illusory ...
Eleanor Jack Gibson (7 December 1910 – 30 December 2002) was an American psychologist who focused on reading development and perceptual learning in infants.

In the classic visual cliff experiments, 12-month-old babies who were separated from their mothers by a plexiglass floor that appeared to represent a dangerous “cliff” looked to their mothers for a cue. [10] When mothers responded to their infants with facial expressions signaling encouragement and happiness, most infants crossed over the ...
