What does research using the "visual cliff" suggest about infants? The original research suggested that older infants could not be enticed to cross the visual cliff while younger infants could.
The original research suggested that infants were not born with the ability to perceive depth but had to learn how to perceive depth.
Later research showed that infants as young as 3 months of age can perceive depth.
The assumption had long been that the avoidance of the visual cliff was related to an infant's fear of heights, but recent research suggests
that infants avoid the drop-off because they sense that they lack the physical skills to make the descent possible.
All of the answers above are correct. Infants are amazing!!!
