When a stimulus is removed from a person or animal resulting in decrease in the probability of response it is known as?

When a stimulus is removed from a person or animal, resulting in a decrease in the probability of a response, it is known as "extinction." In operant conditioning, this occurs when a previously reinforced behavior no longer receives reinforcement, leading to a reduction in that behavior over time. The removal of the stimulus can weaken the association between the behavior and its consequences.
