| [size=18]Psychology is an academic and applied discipline involving the scientific study of mental functions and behavior. Psychologists study such phenomena as perception, cognition, emotion, personality, behavior, and interpersonal relationships. Psychology also refers to the application of such knowledge to various spheres of human activity, including issues related to everyday life (e.g. family, education, and employment) and the treatment of mental health problems. Psychologists attempt to understand the role of these functions in individual and social behavior, while also exploring the underlying physiological and neurological processes. Psychology includes many sub-fields of study and applications concerned with such areas as human development, sports, health, industry, media, and law. Psychology incorporates research from the natural sciences, social sciences, and humanities.
The study of psychology in philosophical context dates back to the ancient civilizations of Egypt, Greece, China, and India. Psychology began adopting a more clinical and experimental approach under medieval Arabian psychologists and physicians, who built psychiatric hospitals for such purposes.
Though the use of psychological experimentation dates back to Alhazen's Book of Optics in 1021, psychology as an independent experimental field of study began in 1879, when Wilhelm Wundt founded the first laboratory dedicated exclusively to psychological research at Leipzig University in Germany, for which Wundt is known as the "father of psychology". The year 1879 is thus sometimes regarded as the "birthdate" of psychology. The American philosopher William James published his seminal book, Principles of Psychology in 1890, laying the foundations for many of the questions that psychologists would focus on for years to come. Other important early contributors to the field include Hermann Ebbinghaus (1850–1909), a pioneer in the experimental study of memory at the University of Berlin; and the Russian physiologist Ivan Pavlov (1849-1936), who investigated the learning process now referred to as classical conditioning.
From the 1890s until his death in 1939, the Austrian physician Sigmund Freud developed a method of psychotherapy known as psychoanalysis. Freud's understanding of the mind was largely based on interpretive methods, introspection and clinical observations, and was focused in particular on resolving unconscious conflict, mental distress and psychopathology. Freud's theories became very well-known, largely because they tackled subjects such as sexuality, repression, and the unconscious mind as general aspects of psychological development. These were largely considered taboo subjects at the time, and Freud provided a catalyst for them to be openly discussed in polite society. While Freud is perhaps best known for his tripartite model of the mind, consisting of the id, ego, and superego, and his theories about the Oedipus complex, his most lasting legacy may be not the content of his theories but his clinical innovations, such as the method of free association and a clinical interest in dreams.
Freud had a significant influence on Carl Jung, whose analytical psychology became an alternative form of depth psychology. Other well-known psychoanalytic thinkers of the mid-twentieth century included Erik Erickson, Anna Freud, Melanie Klein, D.W. Winnicott, Karen Horney, Erich Fromm, and John Bowlby. Contemporary psychoanalysis comprises diverse schools of thought, including ego psychology, object relations, interpersonal, Lacanian, and relational psychoanalysis. Modification of Jung's theories has led to the archetypal and process-oriented schools of psychological thought.
Austrian-British philosopher Karl Popper argued that Freud's psychoanalytic theories were presented in untestable form. Psychology departments in American universities today are scientifically oriented, and Freudian theory has been marginalized, being regarded instead as a "desiccated and dead" historical artifact, according to a recent APA study. Recently, however, South African neuroscientist Mark Solms and other researchers in the emerging field of neuro-psychoanalysis have argued for Freud's theories, pointing out brain structures relating to Freudian concepts such as libido, drives, the unconscious, and repression.
Animal learning experiments are important in many aspects of psychology such as investigating the biological basis of learning, memory and behavior. In the 1890s, physiologist Ivan Pavlov famously used dogs to demonstrate classical conditioning. Non-human primates, cats, dogs, rats and other rodents are often used in psychological experiments. Controlled experiments involve introducing only one variable at a time, which is why animals used for experiments are housed in laboratory settings. In contrast, human environments and genetic backgrounds vary widely, which makes it difficult to control important variables for human subjects.
