Operant conditioning involves learning to choose to engage in certain behaviors in order to receive rewards or avoid consequences.
Operant: a response that has some effect on the world.
3. Thorndike’s Law of Effect If a response made in the presence of a particular stimulus is rewarded, the response is more likely to occur the next time the stimulus is encountered again.
