Original place of publication: scientific american, 202(4), 67-71: questions addressed in original study: (list the 2 5 most important questions addressed in the original study) How are visual skills inborn, if a newborn baby cannot perceive depths: findings of original study: (list the 2 5 most important findings of the original study) The infants crawled across the shallow side, some with hesitancy, but most determined. In the visual cliff example, when the infants were beckoned from the deep cliff side, most babies cried and turned away. Animals have better depth perceptions than humans. Since chicks have to search for food within 24 hours of birth they gain depth perception skills really fast. Lambs are able to stand soon after birth, so on the visual skills test; they had perfect depth perception skills.
