Document Summary

Original place of publication: n/a: questions addressed in original study: (list the 2 5 most important questions addressed in the original study) Do these reactions occur differently due to their development (nurture) and their environment around them: findings of original study: (list the 2 5 most important findings of the original study) A baby needs at least 6 months in order to obtain depth perception and that is through the 6 months of experience they had. On the other hand, chickens and goats almost immediately after birth have this depth perception ingrained in them. Sorce et al (1985) - put children on a medium sized visual cliff and the baby would stop and look down when crossing it. Just like the original study, there was a mother on the other side making different facial expressions to encourage or discourage the baby to cross and that nonverbal communication is called social referencing.
