Psychology covers a huge field and one interesting aspect of it is personality. Personality by itself involves various issues. Some aspects are Psychoanalytic, Ego, Biological, Behaviorist, Cognitive, Trait, and Humanistic. Different types of behaviors are amazing to learn about, mainly the behavior therapy, collective behavior, crime and punishment, and Social behavior and peer acceptance in children. I chose Behaviorism over the other aspects because I believe behavior determines human personality and is very interesting. You can tell what one is by his behavior, and one behaves according to what place he has in society. By doing this paper on Behavior, I hope to get a better understanding of, if behavior develops a personality or if personality guides behavior. I also see behaviorism helping me in the future with my personal and professional career by understanding human personality and behavior better than I do. No matter what your major is, if you can determine one's personality by his behavior you can really get your work done from that person and understand the better than you would otherwise. This person could be your employee or your employer. Behavior Therapy Behavior therapy is the application of experimentally derived principles of learning to the treatment of psychological disorders. The concept derives primarily from work of Russian psychologist Ivan Pavlov. Behavior-therapy techniques differ from psychiatric methods, particularly psychoanalysis, in that they are predominately symptom (behavior) oriented and shows little or no concern for unconscious processes, achieving new insight, or effecting fundamental personality change. The U.S. psychologist B.F. Skinner, who worked with mental patients in a Massachusetts State hospital, popularized behavior therapy. From his work in animal learning, Skinner found that the establishment and extinction of responses can be determined by the way reinforces, or rewards, are given.
