The researchers produced a flat checkerboard pattern that was constructed with different patterns to create the illusion of a “visual cliff” and covered the glass plate over the pattern. Putting the baby’s abdomen from 2 to 3 months down on one side of the “visual cliff” and finding that the baby’s heart rate slows down, which means they experience the depth of the object: when placing a 6-month-old baby on a glass plate When her mother greeted the baby on the other side, she found that the baby would not hesitate to climb over the side without the deep illusion, but would not climb over the side that looks like a cliff, even if the mother is calling the opposite. This seems to indicate that the baby already has deep perception, but this depth perception is innate, or learned in the months after birth, and there is no final conclusion.
