Sixty infants divided evenly between 5 and 7 months of age were tested for their knowledge of object continuity versus discontinuity with a predictive tracking task. The stimulus event consisted of a moving ball that was briefly occluded for 20 trials. Both age groups predictively tracked the ball when it disappeared and reappeared via occlusion,…

Making sense of the visual world requires keeping track of objects as the same persisting individuals over time and occlusion. Here we implement a new paradigm using 10-month-old infants to explore the processes and representations that support this ability in two ways. First, we demonstrate that persisting object representations can be maintained…

Examines the ability of infants to track and anticipate the final orientation of an object. Subjects were infants ranging from an average of four months to eight months old. Three experiments, with the last one as control, were carried out. Concludes that infants show some rudimentary mental rotation from four months of age. (MOK)
