The primary purpose of the dissertation was to determine the presence or absence of binocular interaction in young infants. The anaglyphic (color separation) method of splitting the visual field was employed to present a stimulus continuously to the right eye (continuous stimulus) while another stimulus was flashed (flashed stimulus) to the left eye with neither eye seeing the stimulus presented to the other. The continuous stimuli were darkness, a diffuse light (equal in space-averaged luminance to that of the patterns), a pattern of 20' dots and a pattern of 80' dots. The flashed stimuli were diffuse light, a pattern of 20' dots and a pattern of 80' dots. The dependent measure was the electrical voltage changes recorded over the visual cortex (Oz referenced to the right ear) during the first 500 milliseconds following the flashed stimulus. Any changes in the visually evoked potential related to variations in the continuous stimuli were interpreted as indications of binocular interaction.
