Final answer:
Operant conditioning involves the use of rewards to train animals to perform tricks based on their voluntary behavior.
Step-by-step explanation:
Operant conditioning involves the use of rewards to train animals to perform tricks. The animals learn to associate their voluntary behavior with the reward they receive. For example, if a dog is trained to sit by giving it a treat every time it sits, it will learn to associate sitting with the reward and will be more likely to sit in the future.
