Psychology
The scientific study of behavior and the mind. Psychology is a science in that psychologists employ systematic, objective methods of observation to study any activity that can be observed, recorded, and measured. Additionally, psychologists study the mind (this includes both conscious and unconscious mental states) through inferences made from observable behavior. Psychology includes many subfields, including human development, health, industry, law, and so on. Psychology as a science began in 1879, when Wilhelm Wundt, also known as the father of psychology, established the first laboratory dedicated to psychological research at Leipzig University in Germany. Following this, William James published The Principles of Psychology, which laid the foundation for much of the study of psychology that followed. For more information, see Brain (2002) and James (1890).
