Chapter 14 is about personality and the first section asks the question, "what is it and how can we study it?" Personality is a person's normal ways of thinking, feeling, and behaving. One of the ways that personality is studied is through the studying of twins that were separated at birth, which are called twins reared apart. This kind of study was pioneered at the U of M and took over two decades to complete.
One of the fathers of studying personalities, Sigmund Freud, is a world renowned psychologist that wasn't actually trained in psychology, but rather neurology, which was one of the reasons why he was so successful in studying personalities, however some of theories are controversial and it is still debated today whether or not a few of them are true.
What I found to be most interesting in this chapter was the fact that many of the tests that I was familiar with are not actually accurate. An example of this was the Rorschach Inkblot Test, which is now viewed by many psychologists as unreliable and there are few mental disorders that this test is supposed to detect that it is able to repeatedly indicate the same disorder.
