Until the Second World War, the talk was about "behavioral methodology". In the aftermath of World War II, there was talk of “behavioral sciences”; Where the word behaviorism is no longer closely related to the method of analysis, but has become expressive of a section of the social sciences or a certain amount of knowledge. This term has become a garment that covers and contains three types of cultures: Sociology, where the social milieu is studied. Psychology, where we find the analysis of the moral existence of the individual. then, Biology, where the organic existence of man, or - more precisely - where we find the qualitative study of the functions of organs.
