In this survey of the development of German psychology, the following topics are addressed: (1) the historical development of psychology in West Germany (the pre-World War II period, emigration of a number of prominent German psychologists during the 1930's, the academic vacuum following World War II, re-establishment in the 1960's), (2) contemporary German psychology (the university system, expansion of departments of psychology, increase in the number of students majoring in psychology, establishment of extrauniversity institutes for psychological research), (3) the contributions of contemporary German psychologists (increasing responsibilities to diverse areas of German society, contacts and cooperation at the international level). The article concludes by outlining plans for a cross-cultural study of “aggression”. Hope is expressed for a continuing dialogue between West German and Japanese psychologists.
