In the development of psychiatry it has rarely happened that the description of an isolated phenomenon of experimental psychology has had a great influence on psychopathologic thought. It is therefore of interest to see that from the work on eidetic images which has been done in recent years, many inferences have been drawn with regard to psychiatric problems. Extensive claims have been made as to the light which these studies of the experimental psychology of visual images can throw on questions of pathology. It seems worth while, therefore, to survey briefly the field of these studies and to examine to what extent they actually are advancing the solution of psychopathologic problems.
It has been known for a long time that there are persons who have a pronounced faculty of visualization, a capacity for clearly experiencing subjective visual images. Purkinje, Johannes Müller,1 J. Henle, Fechner, Galton, G. H. Meyer, Lazarus
