Akeelah extended her arm in front of her and then extended one of her fingers. She focused on that finger. Next, she closed her left eye without moving her head; then she opened her left eye and closed her right eye without moving her head. She noticed that her finger seemed to shift as she alternated between the two eyes because of the slightly different view each eye had of her finger. What is illustrated by this example? A: binocular disparity B: bottom-up processing C: oculomotor convergence D: top-down processing
