Sigmund Freud and his associates did much clinical work with the dynamic of projection, especially with regard to paranoid symptoms and syndromes. Much experimental work has also been done with projection. Sears evaluated the results of some of those studies. Murstein and Pryer sub-classified projection and reviewed typical studies. The bibliography lists research with projection between the late 1920's and the middle 1960's. There are many uses of the word "projection". As a Freudian dynamic or mechanism, however, it is in the unconscious ego and related to unpleasure, threat, or anxiety. Many of the studies presented in this bibliography attempt to deal with projection as a Freudian conceptualization. (Author)
