(a) First example of the Disengagement of Attention task. Top: when the clinician is holding one object, when the second object appears, and when the child recognizes the second object. Middle: changes in the yaw motion ( values in the -axis; see Appendices A and B) for every frame ( -axis). The dotted line represents when the second object is presented, followed by boxes representing 1 and 2 seconds after the object is presented. Bottom: 6 examples of the infant’s face during the task. All facial features are automatically detected and tracked (as indicated by the colored boxes around the nose, eyes, and ear). Colors and roman numerals identify corresponding images and spikes in the graph. (b, c) Two examples of the Disengagement of Attention task.
