Of or pertaining to psychophysics; having to do with psychology and physics, or the connexion of the psychical and the physical.
psychophysical isomorphism (see quot. 1932). psychophysical law = psychophysic law. psychophysical methods, ‘methods of experimenting in determining the sensibility for small differences of sensation’ (Billings). psychophysical movement, ‘a hypothetical activity assumed by Fechner to explain the discrepancy between the increase of the stimulus and that of the sensation’ (Billings).
1847H. E. Lloyd tr. Feuchtersleben's Med. Psychol. iii. 151 Habit, likewise, greatly modifies the psycho⁓physical character. 1872Westm. Rev. XLII. 177 As a result of experiments according to all these three methods, Fechner arrives at what he calls a general ‘psycho-physical law’, and also ‘Weber's law’. Ibid. 188 Fechner's law..embodies and illustrates the law of relativity; but it has a psycho-physical value over and above this. 1884tr. Lotze's Metaph. 442 In my eyes, nothing is gained in the way of clearness by the invention of the name ‘psycho-physical occurrence’, or ‘psycho-physical process’. I admit that the expression may have a meaning when applied to a single element, in which, as I said before, we conceive physical and psychical stimulations to exist together. 1886Gurney, etc. Phantasms of Living I. Introd. 43 Artificial displacements of the psycho-physical threshold. 1892C. G. Chaddock tr. Krafft-Ebing's Psychopathia Sexualis v. 403 Large lips, idiotic expression,..and an awkward attitude complete the picture of psychophysical degeneration. 1894Creighton & Titchener tr. Wundt's Human & Animal Psychol. 448 The principle of psychophysical parallelism..refers always to a parallelism of elementary physical and psychical processes. 1903Myers Hum. Personality II. 142 The psycho-physical parallelism—which insists that every mental phenomenon must have a physical correlative. 1932B. Petermann Gestalt Theory ii. iii. 110 He commences with a general leading principle, that of psychophysical isomorphism. This is the assumption that a co-ordination exists between the domain of the experiences and that of the physiological processes..and that it is a co-ordination in the sense of congruence or isomorphism in regard to their systematic properties. 1941, etc. [see interactionism]. 1942W. Koehler Dynamics in Psychol. ii. 43 If an experience A may vary in a specific way, its correlate α must be capable of corresponding variations. When consistently applied, this point of view leads to the principle of psychophysical isomorphism. 1972Sci. Amer. May 30/1 Young's celebrated three-color theory of color vision, published in 1802, was formulated entirely on psychophysical evidence. 1972O. L. Zangwill in Cox & Dyson 20th-Cent. Mind ii. vii. 174 While still at Chicago, Watson had been much troubled by the psychophysical mould in which instruction in experimental psychology was still cast.
Hence psychoˈphysically adv., by psychophysical means; as regards psychophysics.
1847H. E. Lloyd tr. Feuchtersleben's Med. Psychol. v. 307 The so-called proximate cause of idiocy can..be no other than a psycho-physically impeded or depressed vital process. 1894W. James Coll. Ess. & Rev. (1920) 360 Do they mean that introspection acquaints them with a part of the emotional excitement which it is psycho⁓physically impossible that incoming currents should cause? 1948L. Spitzer Linguistics & Lit. Hist. iv. 139 Man, this psycho-physically conditioned being. 1973Nature 21 Sept. 159/2 Gibson and others have shown psychophysically that the gradient of density of visual texture is an important clue to the orientation in depth of textured surfaces. |
