Final answer:
Operant conditioning is indeed about changing behavior by changing its consequences, which is a true statement. It relies on reinforcements and punishments to increase or decrease the likelihood of a behavior's occurrence.
Step-by-step explanation:
The statement that operant conditioning is changing behavior by changing consequences is true. Operant conditioning is a form of learning where an individual's behavior is modified by its consequences. The process involves reinforcements or punishments after the behavior is performed, which then increases or decreases the likelihood of that behavior being repeated.
For instance, psychologist B. F. Skinner used the famous Skinner box to demonstrate operant conditioning, where a rat learned to press a lever to receive food. This kind of learning is vital in both human and animal training, and it's based on the law of effect, which states that actions followed by positive outcomes are likely to be repeated, while those with negative outcomes are less likely.
