Final answer:
Positive reinforcement is rewarding, while negative reinforcement is pleasant.
Step-by-step explanation:
In operant conditioning, positive reinforcement refers to a consequence being rewarding, while negative reinforcement refers to a consequence being pleasant.
Positive reinforcement involves adding a desirable stimulus to increase a behavior. For example, giving a child a sticker as a reward for completing their homework is positive reinforcement.
On the other hand, negative reinforcement involves removing an undesirable stimulus to increase a behavior. For instance, if someone stops experiencing an annoying sound when they fasten their seatbelt in a car, this is an example of negative reinforcement.
