Question

Quizplus · Accepted Answer

Gibson and Walk's research found that babies as young as six months are able to discriminate between deep and shallow and demonstrate avoidance behavior when placed on the "deep" side of the visual cliff apparatus. This suggests that infants are born with a depth perception ability that is present before they are able to crawl or walk. However, the study did not find evidence of depth discrimination in newborns, only in infants who were at least six months old. Therefore, the best answer is B: are able to crawl, reflecting the age group that was tested in the study.
