Positive Punishment: Adding an aversive stimulus to decrease the likelihood of the unwanted behavior occurring again, like giving your sibling extra chores for barging into your room.
Negative Punishment: Removing a desired stimulus following the undesired behavior, such as taking away their favorite toy for interrupting your study time.
Extinction: The process of gradually eliminating unwanted behavior by no longer reinforcing it, like pretending not to notice when your sibling interrupts you until they stop doing it.
