Two examples of the ball playing activity. Top: when the ball contacts the child, when the child looks down at the ball, and when the child looks up at the clinician. Middle: changes in the pitch motion (𝑦-axis) for each frame (𝑥-axis). The dotted line represents when the ball contacts the participant. Bottom: 6 examples of the infant’s face during the administration. All facial features are automatically detected and tracked. Colors and roman numerals identify corresponding images and spikes in the graph.
