Contrast sensitivity of the human infant for moving and static patterns

A fixation preference method was used to assess contrast sensitivity of 1–3-month infants for stationary and drifting (3-Hz) sinusoidal gratings. The infants showed greater sensitivity for moving gratings at low spatial frequencies, but at their acuity limits there was no difference between static and moving stimuli. We conclude that the advantage of moving stimuli at low spatial frequencies reflects a differential sensitivity similar to that of the adult.
