psychology in ambiguity of its definition

While psychologists do train, research, even practice clinical interventions, without any doubt about the subject of their study and science, they still obscure the issue of psychology, the "psychic" concept. Although passing at least one century since the recognition of the science of psychology and the extraordinary development of branches and different psychological trends, there is still no consensus about this issue. Psyche, mind, behavior, and psychological processes have been interpreted in the history of human knowledge since the beginning of its production and at least its registration has been used up to now. This paper, with its focus on the dissection of the subject of psychology in the history of science, seeks to review this ambiguity and to show the dominance of this ambiguity in the present situation.
