If you’ve ever been asked the question “What makes you tick?” you may have found it harder to answer than you realized. After all, if you don’t know yourself, who does? The reason this question is so hard to answer is that we don’t often think about our basic thoughts, feelings, and behavior. By learning about psychology’s major personality theories, you’ll gain self-insights into why you do what you do and how, if you want, you can change.
You might think that psychology decided long ago how to define personality. After all, this is one of the basic concepts that psychologists study. It turns out that there are almost as many definitions of personality as there are psychologists. From Freudians to Skinnerians, and everything in between, psychologists offer definitions that reflect their basic philosophy about the fundamentals of human nature.
If you’re not given to philosophical debates and would just like to know how to understand yourself, there’s hope. Most psychologists agree on a working definition of personality to guide them in their professional work, research, and even personal lives, that personality is an individual’s characteristic ways of feeling or behaving. Different psychologists emphasize feelings, behavior, and the underlying reasons that people feel and behave in certain ways. However, all psychologists view personality as a characteristic of the individual, meaning that it is the basis for differences from person to person.
