Psychology

Psychology (Classical Greek: psyche = "soul" or "mind", logos = "study of") is an academic and applied field involving the study of behavior, mind and thought and the neurological bases of behavior. Psychology also refers to the application of such knowledge to various spheres of human activity, including problems of individuals' daily lives and the treatment of mental illness. It is largely concerned with humans, although the behavior and mental processes of animals can also be part of psychology research, either as a subject in its own right (e.g. animal cognition and ethology), or somewhat more controversially, as a way of gaining an insight into human psychology by means of comparison (including comparative psychology). Psychology is commonly defined as the science of behaviour and mental processes. Although its name derives from Greek "psyche", psychology does not scientifically study the soul, since no evidence exists to show such a thing exists.

The late 19th century marks the start of psychology as a scientific enterprise. The year 1879 is commonly seen as the start of psychology as an independent field of study, because in that year German scientist Wilhelm Wundt founded the first laboratory dedicated exclusively to psychological research in Leipzig, Germany. Other important early contributors to the field include Hermann Ebbinghaus (a pioneer in studies on memory), the Russian Ivan Pavlov (who discovered the learning process of classical conditioning), and the Austrian Sigmund Freud. Freud's influence has been enormous, though more as cultural icon than a force in (scientific) psychology. Freud's basic theories postulated the existence in humans of various unconscious and instinctive "drives", and that the "self" existed as a perpetual battle between the desires and demands of the internal id, ego, and superego.

The mid-20th century saw a rejection of Freud's theories among many psychologists as being too unscientific, as well as a reaction against Edward Titchener's abstract approach to the mind. This led to the formulation of behaviorism by John B. Watson, which was popularized by B.F. Skinner. Behaviorism proposed epistemologically limiting psychological study to overt behavior, since that could be quantified and easily measured. Scientific knowledge of the "mind" was considered too metaphysical, hence impossible to achieve. The final decades of the 20th century have seen the rise of a new interdisciplinary approach to studying human psychology, known collectively as cognitive science. Cognitive science again considers the "mind" as a subject for investigation, using the tools of evolutionary psychology, linguistics, computer science, philosophy, and neurobiology. This new form of investigation has proposed that a wide understanding of the human mind is possible, and that such an understanding may be applied to other research domains, such as artificial intelligence.
