<P> Areas of research in which Lasswell worked included the importance of personality, social structure, and culture in the explanation of political phenomena . Lasswell was associated with the disciplines of political science, psychology, and sociology--however he did not adhere to the distinction between these boundaries but erased the lines drawn to divide these disciplines . </P> <P> Lasswell is well known for his model of communication, which focuses on "Who (says) What (to) Whom (in) What Channel (with) What Effect". </P> <P> He is also known for his book on aberrant psychological attributes of leaders in politics and business, Psychopathology and Politics, as well as for another book on politics, Politics: Who Gets What, When, and How . </P> <P> Lasswell studied at the University of Chicago in the 1920s, and was highly influenced by the pragmatism taught there, especially as propounded by John Dewey and George Herbert Mead . However, more influential on him was Freudian philosophy, which informed much of his analysis of propaganda and communication in general . During World War II, Lasswell held the position of Chief of the Experimental Division for the Study of War Time Communications at the Library of Congress . He analyzed Nazi propaganda films to identify mechanisms of persuasion used to secure the acquiescence and support of the German populace for Hitler and his wartime atrocities . Always forward - looking, late in his life, Lasswell experimented with questions concerning astropolitics, the political consequences of colonization of other planets, and the "machinehood of humanity". </P>
