Answer:
Reinforcement : extinction
Explanation:
Reinforcement is used in operant conditioning and it refers to anything that increases the likelihood that a response will occur.
Extinction is very similar as a form of punishment such that it helps in reducing unwanted behavior.
When Mary raises her hand, the teacher calls on her, but when Mary blurts out an answer the teacher ignores her and calls on another student. As a result, Mary's behavior of raising her hand increases, and her behavior of blurting out answers decreases. The teacher used REINFORCEMENT on Mary's behavior of raising her hand and EXTINCTION on her behavior of blurting out answers.
