Final answer:
Positive punishment occurs when an undesirable stimulus is added to decrease a behavior, while negative reinforcement involves removing an undesirable stimulus to increase a behavior.
Step-by-step explanation:
Positive punishment occurs when an undesirable stimulus is added to decrease a behavior. This is different from negative reinforcement, which involves removing an undesirable stimulus to increase a behavior.
An example of positive punishment would be scolding a student to get them to stop texting in class. In this case, the stimulus of the reprimand is added to decrease the behavior of texting in class.
In contrast, negative reinforcement is when an undesirable stimulus is removed to increase a behavior. An example of this is a car seatbelt system that beeps until the seatbelt is fastened. The annoying sound stops when the desired behavior of fastening the seatbelt is exhibited.
