Gerhard H. Fischer

from Wikipedia, the free encyclopedia

Gerhard Hakon Fischer (born December 12, 1938 in Vienna ) is an Austrian psychologist and emeritus professor of psychology at the University of Vienna .

Life

Fischer majored in psychology and minor in mathematics at the University of Vienna. In 1961 he became a research assistant at the institute and worked for Erich Mittenecker . He received his doctorate in 1963 and left the institute in 1964 to become an assistant at the Institute for Advanced Studies in its department of sociology. In 1966, at Hubert Rohracher's invitation, he returned to the Institute of Psychology as an assistant and was entrusted with statistical exercises for psychologists as well as planning and carrying out psychological experiments.

After a research stay with the statistician Georg Rasch in Copenhagen , he published on item response theory and completed his habilitation in 1968 with Slawtscho Sagoroff. He then received a call to a full position in statistics at the University of Konstanz and a position to a full position in psychological methodology and mathematical psychology in Vienna.

Services

At the University of Vienna, Fischer usually gave a two-semester lecture on methodology including exercises, as well as a introductory seminar on formalized models of psychological processes. In the 1974/75 academic year, Fischer became chairman of the university's building commission and from 1975 to 1984 he was also the director of the University of Vienna's inter-faculty IT center. Fischer was elected several times to the board of the Institute for Psychology.

Gerhard Fischer deserves the credit for making the probabilistic test theory in the sense of Rasch's models, which are again closely related to Paul Lazarsfeld's "latent structure theory" , known in the German-speaking area and developing it further. Further fields of activity of Fischer were factor analysis and its application.

Assistants and successors

Fischer's first assistants were Hartmann Scheiblechner and Hans Spada , who both also dealt with item response theory. Another assistant to Fischer was Anton K. Formann , who after Fischer's retirement took over the management of the department for methodology and differential psychology.
