Final answer:
The statement is true; both presentation (positive) and removal (negative) punishment aim to decrease behaviors by adding or removing stimuli, respectively.
Step-by-step explanation:
True. Presentation and removal punishment both serve as forms of behavior modification techniques that aim to decrease the likelihood of a behavior occurring again. Presentation punishment involves the introduction of an aversive stimulus (such as a scolding or detention) following a behavior, while removal punishment involves the removal of a desired stimulus (such as taking away privileges or toys) following a behavior.
By associating a negative consequence with the behavior, both presentation and removal punishment create disincentives for engaging in the behavior in the future. However, it is important to note that punishment is not always the most effective method of behavior modification, as it can have negative side effects and may not address the underlying causes of the behavior.
