This report examines the causes of error in two techniques for measuring eye fixation position. Theoretical calculations of the magnitude of sources of error are shown to produce good agreement with empirically derived magnitudes for adult and neonate eyes.

Three experiments are reported in which 15 babies were presented with visual stimuli which varied in shape and distance from the eye. Results indicated that the majority of subjects binocularly fixated all three stimuli and it was concluded that the newborn baby has the basic requirements for binocular vision. (Author/GO)

Two experiments assessed the extent of newborns' ability to discriminate color. Results imply that newborns have some, albeit limited, capacity to discriminate chromatic from achromatic stimuli, and hence, are at least dichromats. (Author/DR)

Studied infant ability to extract depth information from a three-dimensional structure. Found evidence that 8-month-old infants distinguished between lines indicating edges, and lines indicating markings, and that they are able to use line junctions to perceive line drawings as depicting three-dimensional objects in the picture plane.

Visual orientation toward a peripheral stimulus by newborns and 7-week-old infants was examined with both a central stimulus present and absent. General conclusion is that, contrary to previous assessments, the neonate appears to exercise internal control over his sampling of the stimulus array rather than being passively captured by it.…
