Posture as a determinant of visual behavior in newborns.
The effects of posture on the visual behavior of 15 3-day-old healthy black newborn males and females were assessed. The amount of time each infant kept his eyes open and the quality of fixation and following a visual stimulus were measured in each of 3 positions: lying down, sitting up, and on shoulder. Although position had little effect on the amount of time the eyes were open, the on-shoulder position significantly increased the quality of the visual behavior. These findings suggest that the vestibular, proprioceptive, and contact stimulation provided by the on-shoulder position affects the newborn's ability to follow and process visual stimuli.
