Infrared television recordings were made of newborns' visual activity under monocular and binocular viewing conditions. Out-of-control eye movements were substantially more frequent in the presence of uniform light fields than in darkness for both groups. A distinction between exogenous and endogenous control of eye movements in newborns is…

Experiments presented indicate that perseverative error in year-old infants cannot simply be a memory problem. Possible explanations are examined. (Author/ED)

A series of experiments is described whose aim was to define certain of the effective dimensions of stimulation in the newborn's visual environment. (Author/JMB)

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)
