RELATIONAL PSYCHOPHYSICS – MAJOR MESSAGES FROM HERMANN EBBINGHAUS’ AND MAX WERTHEIMER’S WORK

  • Viktor Sarris

Abstract

In past and modern research some main philosophical and methodological issues of human and animal perception have been discussed, with special emphasis on the relational basis of psychophysics. For example, the question has been raised if, and to which extent, there are viable bridges between traditional gestalt-oriented approaches and modern perceptual-- cognitive work. Thereby the key concept of “frame of reference†is illustrated here by pointing to Hermann Ebbinghaus’ classic geometric-optical illusions ( cf. the Ebbinghaus- Titchener illusion), on the one hand, and Max Wertheimer’s gestalt theory of the transposition phenomenon, on the other.
