Final answer:
Reinforcers increase behavior likelihood, while punishers decrease it in operant conditioning.

Reinforcers are events that, when they follow a behavior, increase the probability of the behavior repeating. In operant conditioning, positive reinforcers refer to objects or events that strengthen a behavior. Reinforcers increase the likelihood of a behavior being repeated, whereas punishers decrease the probability of the behavior recurring.
