Psychology is the scientific study of the mind and behaviour, according to the American Psychological Association. Psychology is a multifaceted discipline and includes many sub-fields of study such areas as human development, sports, health, clinical, social behaviour and cognitive processes. Psychology is really a very new science, with most advances happening over the past 150 years or so.  However, its origins can be traced back to ancient Greece, 400 – 500 years BC. In the early days of psychology there were two dominant theoretical perspectives regarding how the brain worked, structuralism and functionalism. Structuralism was the name given to the approach pioneered by Wilhelm Wundt (1832-1920), which focused on breaking down mental processes intro the most basic components. The term originated from Edward Titchener, an American psychologist who had been trained by Wundt. Wundt was important because he separated psychology from philosophy by analysing the workings of the mind in a more structured way, with the emphasis being on objective measurement and control.
