Final answer:
Negative punishment is being used to stop Mazie's behavior when Dustin pays no attention to her.
Step-by-step explanation:
When Dustin pays no attention to Mazie, he is using negative punishment to stop her behavior. Negative punishment is the removal of a pleasant stimulus to decrease a behavior. In this case, Dustin is removing attention to decrease Mazie's behavior.
Positive reinforcement would involve adding an enjoyable stimulus to increase behavior, negative reinforcement would involve removing an aversive stimulus to increase behavior, and positive punishment would involve adding an undesirable stimulus to decrease behavior.
