From Wikipedia, the free encyclopedia

Psychology (Greek: ψυχολογία) is the academic and applied study of behavior, cognition and their underlying mechanisms. It primarily applies to humans but can also be applied to non-humans such as animals or artificial systems. Psychology also refers to the application of such knowledge to various spheres of human activity, including problems of human beings' daily lives and the treatment of mental illness. The field contains a range of sub-areas (for instance the studies of development, personality and language), as well as many different theoretical orientations (such as behaviorism, evolutionary psychology and psychoanalysis). Psychology draws from a number of other fields of study, including biology, sociology, anthropology and philosophy.
