In "Can't Feel My Face" by The Weeknd he recognizes the dangers of using the drug singing, "And I know she'll be the death of me" and "she'll always get the best of me the worst is yet to come." However, he says he cannot go without it because of the feeling that he has when he is high as it numbs the pain and allows him to stop worrying. His addiction is explained through the line, “She told me don’t worry about it.” He personifies the drug as a girl, while explaining that the drug is calming to him and the reason behind him continuously returning to it. He sings, “We both know we can’t go without it,” and he believes this because of his psychological dependence on the drug. Cocaine convinces him that even the worst-case scenario of death is worth the high because he will at least "be beautiful and stay forever young.” 

     Chapter 1 from the textbook defines the psychodynamic perspective as the explanation of behavior through past experiences and motivational forces. This perspective focuses on unconscious thought and behavior, and it is aggressive in nature. The transition from the polite and bashful family-man from the beginning of the show to the villain under the name of Heisenberg that wouldn't let anything stop him from feeding his own ego can best be described by the psychodynamic perspective in psychology. After all of Walt’s hard work and research in the chemistry field, all he amounted to be was a high-school chemistry teacher. He had goals of starting his own successful research company, Gray Matter, but he sold his share to his friends for $5,000 and it later became a multi-billion dollar company. He felt as if his work was stolen from him by his friends, and he secretly blamed them for his financial problems late in life. Additionally, Walt is very close to his brother-in-law, Hank, who is a DEA agent with a personality that greatly contrasts Walt’s in the beginning of the show. Walt is portrayed as a goofy nerd that hadn’t accomplished much in his life, whereas Hank is the true “man” in the family that continuously teases Walt. While Walt may have believed in the beginning that he was killing people, selling meth, and tearing apart relationships to provide for his family, it was very clear by the end that this business gave him a sense of purpose and fulfillment. After all, the feeling of being alive and accomplished was the true motivational force behind his shift in aggressive behavior, not his family.

     The incentive to earn more points caused the employees to work harder than they ever had. In this case, the points are classically conditioned to be a secondary reinforcer since they can be used to purchase a primary reinforcer. The tattoo would cause the employees pleasure because of the instant amusement they would get out of watching Andrew tattoo his butt, and it is therefore a primary reinforcer. The group needed exactly 5,000 points to earn the reward, which demonstrates a fixed ratio schedule of reinforcement. This strategy is less effective than a variable interval schedule in the long run because the likelihood of the intended behavior being repeated after the reinforcer is removed fades at a faster rate. It is a very predictable strategy, and it can be expected that the employees at Dunder Mifflin will revert to their old habits if the point system is removed. However, they did receive their primary reinforcer because Andrew went through with getting the tattoo. Therefore, if the point system is continued, we can expect a similar amount of production since the incentive to work hard is still there. 

            After Benny gets the ball and runs around town away from the dog, he returns to the sandlot where the dog gets trapped under the fence. He saves the dog but is now nervous about how the owner of the home will react to the damaged property. The owner chuckles, invites them in to talk about baseball, and asks, “why didn’t you just knock on the door? I would have gotten it for you.” Benny and the rest of the group got the baseball back and realized there was not much to fear after all. Parasympathetic division is finally able to calm them down as it slows the heart and breathing, constricts the pupils, reactivates digestion and excretion, and stops sending signals to the adrenal glands. All the energy that they burned from stressing over the baseball and running around town can now be restored. While Benny may credit his PF Flyers for allowing him to jump higher and run faster, the autonomic nervous system was clearly the true secret weapon at work here.
