Presentation punishment is when a new stimulus is presented in response to a behavior in an effort to decrease the behavior. Examples include spanking, dirty looks, and being yelled at. An example of presentation punishment: Melissa throws a fit when she has to go to bed, and her mom spanks her in order to stop her from crying. The next time Melissa is sent to bed, she might not cry because she doesn't want to get spanked.
Removal punishment is the removal of a previously existing stimulus in response to a behavior. Removal can mean the loss of privilege or freedom (grounding...). For instance, Bob keeps making fun of his brother, so his mom takes away his nintendo. The next time Bob thinks he wants to make fun of his brother, he might decide not to in order to avoid the removal punishment.
