Abstract

72 human newborns were randomly assigned to 24 groups. Each group monocularly viewed a plain field and 1 of 24 figures resulting from all possible combinations of black and white, solid and outline circles, and triangles of 3 magnitudes. Corneal-photographic records of scanning were computer-analyzed for: (1) location of gaze, (2) dispersion of gaze, (3) number of shifts in gaze, (4) direction of shifts, (5) length of shifts, and (6) time spent looking directly at the total figure, only part of the figure, contour vs. centers of circles, or sides vs. angles of triangles. Significant effects, as a function of stimulus condition, were found for all factors except number of shifts in gaze. (15 ref.) (PsycINFO Database Record (c) 2006 APA, all rights reserved)
