The “visual cliff” is a pane of glass covering a shallow surface on one half and a deep surface on the other half.
When babies only 6 months old are placed on the shallow side, they will refuse to crawl out over the cliff.
At only 2 months of age, babies placed on the deep side show a drop in heart rate indicating that they can perceive the depth and are interested in it.
