FIGURE 1.

(A) Example frame from the video stimuli, in which an adult performed a continuous sequence of actions with the six possible objects on the toy. (B) Following observation, infants’ grasping abilities were assessed using the pictured apparatus, which required them to extract the bead from the wooden board. (C) Schematic illustrating the statistical structure of the action sequence containing two deterministic pairs that caused a light effect: one pair was performed with a pincer grasp and the second with a whole-hand grasp. Numbers represent transitional probabilities between paired and random actions. Dotted lines underneath the first action of a pair depict the 4 second period preceding the target actions in which predictive gaze fixations were analyzed.
