Final answer:
In operant conditioning, reinforcement, whether positive or negative, ideally should strengthen the desired behavior.
Step-by-step explanation:
In operant conditioning, any form of reinforcement, positive or negative, ideally should strengthen the desired behavior. Positive reinforcement involves adding a desirable stimulus to increase a behavior, while negative reinforcement involves removing an undesirable stimulus to increase a behavior. Both types of reinforcement aim to increase the likelihood of a desired behavior occurring in the future.
