Final answer:
A satiation decreases the effectiveness of a reinforcer and makes it less likely that the behavior will be repeated to obtain it. Reinforcement is used to increase behaviors, while punishment is used to decrease them.
Step-by-step explanation:
A satiation decreases the efficacy of a reinforcer (makes it less potent) and decreases the likelihood of behavior to obtain that reinforcer. In the context of operant conditioning, when discussing behavior modification, reinforcement is the implementation of a consequence to increase a behavior, whereas punishment is applied to decrease a behavior. Positive punishment adds an undesirable stimulus to decrease a behavior, while negative punishment involves removing a pleasant stimulus to decrease a behavior. An example of negative punishment is when a child misbehaves and a parent takes away a favorite toy, thus removing a stimulus to decrease the unwanted behavior.
