A Longitudinal Study of the Visual Control of Posture in Infancy
James L. Rose, Bennett I. Bertenthal · 2019
During movement of an observer, the pattern of light reflected to the eyes undergoes a lawful transformation resulting in an optical flow pattern. A great deal of research to date has addressed the role of optical flow perception in the regulation of balance and self-produced locomotion. In addition, developmentalists have focused on the emergence of optical flow sensitivity and the age-related changes in flow perception and motor coordination. Infants between 5 and 13 months of age were presented a sinusoidally oscillating visual scene while their postural responses were measured with a force plate. The findings suggested that some degree of integration between visual information and sitting responses exists early, prior to the onset of independent sitting, and is refined with development. Infants between 5 and 13 months of age were presented a sinusoidally oscillating visual scene while their postural responses were measured with a force plate.
