Final answer:
Positive punishment is adding an undesirable stimulus to decrease a behavior, while negative punishment is removing a pleasant stimulus to decrease behavior.
Step-by-step explanation:
Adding something bad to decrease a behavior is known as positive punishment. In positive punishment, you add an undesirable stimulus to decrease a behavior. For example, scolding a student to get them to stop texting in class is an example of positive punishment. The scolding is added as a stimulus to decrease the behavior of texting in class.
Another form of punishment is negative punishment, where you remove a pleasant stimulus to decrease behavior. For instance, a parent taking away a favorite toy when a child misbehaves.
