Studies relate to the evolution to 1978; an overview of the literature on causes of terrorism; psychological characteristics of West German terrorists and possible motivations for their behavior; and terrorism as a disturbance of the developing personality according to Erikson's thesis; the influence of family dynamics, school experiences, and socioeconomic status on the evolution of radical rightists and leftists; and an analysis of the state of monoperceptosis (i.e, obsession with a particular idea) which is illustrated with the case of a young murderer and then applied to terrorists. The final essay outlines the possible causes of terrorism which are with potential for application to police preventive measures. A bibliography, biographies of authors, separate notes for a number of the essays, and a chronological list of important events in the evolution of West German terrorism are supplied.
