Reinforcement strategy

Positive and negative reinforcement, this video shows you a real example of its use.

Maybe you have seen this TV series which is called "The Big Bang Theory" here are two geeks with a sexy girl who is the girlfriend of one of them, Leonard. On the other hand, Sheldon is freaky intelligent boy who in this case is applying the skinner statement trying to modify the behavior of her who represents a human being with a lot of incongruent habits. he use positive reinforcement with her during the video in different situations who for him is wrong but she noticed alone about it and create and stimuli with the help of chocolate, but with the boyfriend, Leonard who is against to this experiment, feeling his girlfriend is like a laborat rat, receive an negative reinforcement.

Although Sheldon confuses negative reinforcement with punishment. Negative reinforcement is used to increase the frequency of a behavior whereas punishment is used to decrease the frequency of a behavior.

This is an interesting theory in second language acquisition where you can apply it and expect for an outcome but is it really the process of learning or just and expectations where the time make it forget fast?
