PERCEPTION (from See also:Lat. percipere, to perceive) , in See also:psychology, the See also:term specially applied to the See also:mental See also:process by which the mind becomes conscious of an See also:external See also:object; it is the mental completion of a sensation, which would otherwise have nothing but a momentary existence coextensive with the duration of the stimulus, and is intermediate between sensation and the " ideal revival," which can reinstate a perceptual consciousness when the object is no longer See also:present. This narrow and precise usage of the term " perception " is due to See also:Thomas See also:Reid, whose view has been generally adopted in principle by See also:modern psychologists. On the other See also:hand some psychologists decline to accept the view that the three processes are delimited by See also:sharp lines of cleavage. It is held on the one hand that sensation is in fact impossible as a purely subjective See also:state without See also:cognition; on the other that sensation and perception differ only in degree, perception being the more complex. The former view admits, which the latter practically denies, the distinction in principle. Among those who adopt the second view are E. B. Titchener and See also:William See also:James. James (Principles of Psychology, ii. 76) compares sensation and perception as " the barer and the richer consciousness," and says that " beyond the first crude sensation all our consciousness is a See also:matter of See also:suggestion, and the various suggestions shade gradually into each other, being one and all products of the same psychological machinery of association." Similarly See also:Wundt and Titchener incline to obliterate the distinction between perception and ideal revival. See also:Prior to Reid, the word perception had a See also:long See also:history in the wider sense of cognition in See also:general. See also:Locke and See also:Hume both use it in this sense, and regard thinking as that See also:special See also:kind of perception which implies deliberate See also:attention.
