This week at Keene State College students had Thanksgiving break, so I only had one personality theories class for the whole week. The class was interesting because of the lecture and discussions and because of the in class writing assignment. The in class writing assigment was about whether I thought medicine or therapy was a more effective treatment for a depression or anxiety problem. Like most of the class I said that therapy would probably be the best route, but I also said that if therapy is ineffective then medicine can be an important alternative. I think also that if someone is being treated on a psychiatric medicine that it can be important they see a therapist, who can tell them about how they are doing overcoming there problem. I also began to read through some of chapter eleven, which looks like it will be the last chapter we will be covering this semester. The chapter talks about Raymond Catell's theory, known as the the Big Five Personality Trait Theory. Catell found that the personality contains five primary factors, which are neuroticism, extraversion, openess, agreeableness, and conscientiousness. The Big Five Personality Trait theory was established through research on language, which allowed researchers to understand a descriptive model of personality characteristics. This personality theory was also developed through the studying of personality questionnaires, which then led to the development of the Five Factor Model that explains dispositonal inherrited biological traits. I think that like all the theories in the personality textbook this should be an important one because it was created through alot of extensive and interesting research.
