Each time the rat hit the lever, a pellet of food came out. After eating the pellet, what do you think the hungry rat did next? It hit the lever again, and received another pellet of food. At first, the rat might randomly hit the lever while exploring the box, and out would come a pellet of food. For example, Skinner used positive reinforcement to teach rats to press a lever in a Skinner box. Remember, the best way to teach a person or animal a behavior is to use positive reinforcement.
Distinguish between reinforcement schedules.
