Answer:
The answer is: Positive reinforcement
Step-by-step explanation:
As part of a system known as operant conditioning, positive reinforcement involves adding a reinforcing stimulus (in this case a plastic chip that can be exchanged for a a prize) following a good/desired behavior to make it more likely that the same or similarly good/desired happens again in the future. When a positive outcome or reward comes after certain actions, that same type of action will be strengthened and likely to be repeated in the future.
