Psychology
Psychology is the science of behaviour and mind, embracing all aspects of conscious and unconscious experience as well as thought. It is an academic discipline and a social science, which seeks to understand individuals and groups by establishing general principles and researching specific cases.
Psychologists use human behaviour as a clue to the workings of the mind. Although we cannot observe the mind directly, everything we do, think, feel and say is determined by the functioning of the mind. So psychologists take human behaviour as the raw data for testing their theories about how the mind works.
Since the German psychologist Wilhelm Wundt (1832-1920) opened the first experimental psychology lab in Leipzig in 1879, we have learned an enormous amount about the relationship between brain, mind and behaviour.
