During substage 5 (12 to 18 months) of Piaget's sensorimotor development, infants begin to experiment with new behavior to see what effects they can cause, showing a clear understanding of cause and effect. Timothy O.'s actions of observing the sounds different items make when they hit the floor and walls, and noting the caregiver's reactions, align with this experimental and exploratory behavior characteristic of substage 5.
