Extinction in operant conditioning involves __________

A) negative reinforcement.
B) positive reinforcement.
C) punishment.
D) withholding reinforcement.

Extinction in operant conditioning involves withholding reinforcement. This means that a previously reinforced behavior is no longer reinforced, which leads to a decrease in the frequency and persistence of that behavior. It is important to note that extinction is not the same as punishment, which involves the addition of an aversive stimulus to decrease behavior.
