ABSTRACT
One of the reasons for the oblivion into which the Graz psychologists sank was undoubtedly, as often recalled, the difficult language and the complex philosophical theory that underlay their experimental results and prompted their laboratory research. Regarding Graz's psychological theories in particular, Metzger makes several references to the theory of production in Psychologie, although he seems to have misunderstood some of its crucial aspects. Some appreciation of the Graz legacy is to be found in Metzger and in Witte, who considered the Ehrenfelsian concept of 'transposition of structures' as the core of psychology. A more general and crucial aspect of the question is the cleavage that opened up after the 1930s between philosophical theory and psychological experimentation. In particular, reactualizing the Graz school might give new insight in one of the questions more up to date in contemporary psychological debate: i.e whether perception has to be assimilated to mental higher processes of cognition or viceversa.
