We investigated 6- to 12-month-old infants’ ability to track an object moving on circular trajectories, using a longitudinal design. Consistent predictive gaze tracking was not found before 8 months of age. These results indicate that infants’ horizontal and vertical components of circular tracking are less mature than expected from previous studies of one-dimensional horizontal tracking. Vertical components are especially immature, particularly during high velocity tracking (~20°/s). The results also suggest that horizontal and vertical tracking are mutually dependent during early development. Saccades were predictive (average lag >−125 ms) from 6 months onwards.
