Clinical psychology is an integration of science, theory and clinical knowledge for the purpose of understanding, preventing, and relieving psychologically-based distress or dysfunction and to promote subjective well-being and personal development. Central to its practice are psychological assessment, clinical formulation, and psychotherapy, although clinical psychologists also engage in research, teaching, consultation, forensic testimony, and program development and administration. In many countries, clinical psychology is a regulated mental health profession.
Psychology is the science of behavior and mind, including conscious and unconscious phenomena, as well as feeling and thought. It is an academic discipline of immense scope and diverse interests that, when taken together, seek an understanding of the emergent properties of brains, and all the variety of epiphenomena they manifest. As a social science it aims to understand individuals and groups by establishing general principles and researching specific cases.
Unlike the physicist, the psychologist … investigates processes that belong to the same order — perception, learning, thinking — as those by which he conducts his investigation.
Morris R. Cohen, Reason and Nature (1953), p. 81
The great shift … is the movement away from the value-laden languages of … the “humanities,” and toward the ostensibly value-neutral languages of the “sciences.” This attempt to escape from, or to deny, valuation is … especially important in psychology … and the so-called social sciences. Indeed, one could go so far as to say that the specialized languages of these disciplines serve virtually no other purpose than to conceal valuation behind an ostensibly scientific and therefore nonvaluational semantic screen.
Thomas Szasz, Anti-Freud (1990), p. 44
