Visual Scanning by Human Newborns: Responses to Complete Triangle, to Sides Only, and to Corners Only.
Nelson, Keith; Kessen, William
This study tested the hypothesis that newborns selectively orient toward angular elements in their visual field. Subjects were 36 awake and alert infants under 6 days of age. For each newborn, the study compared visual attention to three separately presented stimulus patterns: a complete outline triangle, only the sides of this triangle, and only the angles. Newborns were initially shown a circular panel consisting of a homogeneous black field. At least 15 frames at the rate of one per second were obtained with one of the infant's eyes covered. Fifteen frames were then obtained for each of the experimental stimulus patterns. Analysis of dependent means revealed that regional contour scores did not significantly differ for control and sides-only stimuli. However, both angles-only and complete triangle patterns attracted significantly more ocular orientations than the homogeneous control stimulus. These results reaffirm the conclusion of Salapatek and Kessen (1966) that angular elements of a triangle are elements which attract the infant's gaze independently of the presence or absence of side contours. Scanning records revealed that infants looked only toward a single angular component. More detailed analyses of orientation are planned. (JF)
