The questions in this series may appear to have nothing in common, except that they are all pondered, at one time or another, by curious people. But, in fact, they do have something in common, because they are all questions dealt with in the field of psychology. If you are not yet excited to study psychology, you probably did not realize the wide variety of intriguing questions for which psychology provides insights. It is also possible that you are not even sure what psychology is all about. It is one of those things that most people know exists, but have a hard time defining clearly.
Psychology is the scientific inquiry into many aspects of the human mind and experience.
These aspects include sensation, perception, consciousness, thought and intelligence, emotions and motivation, personality, and interaction with other individuals and society. In fact, behavior is so important that psychology is sometimes described as the study of behavior. Psychology can also be defined in terms of its objectives. As we hinted with the series of questions above, psychology is extremely interdisciplinary in nature. It originated as a combination of two disciplines, philosophy and physiology, and has extended its influence to many others.
