Peer reviewedRichards, John E.; Rader, Nancy – Journal of Experimental Psychology: Human Perception and Performance, 1981
Two experiments tested the effects of crawling-onset age, amount of crawling experience, and testing age on avoidance of the deep side of a visual cliff apparatus by human infants. Crawling-onset age disciminated between infants because crawling during the tactile phase interferes with later visual control of locomotion. (Author/RD)
