To devise a plan using reinforcement and punishment, in order to change your friend's behavior so that he spends less time playing video games, it is necessary to change your perception of his actions.
Reinforcement refers to the stimulus of the behavior, which can be positive when there is a stimulus that involves the repetition of the behavior in the future, due to a favorable outcome after the action.
Negative reinforcement, on the other hand, corresponds to the removal of a negative result to perform an action.
Positive occurs when there is the purposeful use of an unfavorable result after a behavior considered inappropriate. Negative punishment is related to taking something you want out of a situation to decrease the behavior you want to change.
Therefore, using both theories, a plan for someone to spend less time playing video games could spend more time with their friends, as a positive reinforcement, and pre-program their device to turn off after a certain time, as a negative reinforcement.
On the other hand, a positive punishment could be having to clean your room every time you spend a lot of time using the video game, and as a negative punishment, it could be disconnecting the internet to reduce the behavior.
