This study examined the development of smooth visual tracking in 11 infants 2 and 3 months of age, with particular attention given to the role of expectation in tracking complex visual motion. Data were gathered by recording the image of the infant's eye as he or she tracked a small computer-generated target as it moved in a sinusoidal trajectory…

In a visual recognition masking experiment, a target stimulus to be identified is either preceded or followed by a second stimulus called a masking stimulus. The experiments described here provide estimates of both developmental and aging differences in visual backward masking under conditions which maximize interference in the central visual…

Reported are three series of experiments analyzing the development of the visual function of infants. The first experimental series was aimed at the investigation of infants' reaction to moving objects. The second experimental series dealt with the analysis of the development of binocular vision in infants. The goal of the third series was to…
