Abstract
"Based upon a random sample of entries from each fifth volume of the Psychological Index and the Psychological Abstracts, trends in the area of subject interest, journal sources of psychological literature, and language have been analyzed. Of the 12 subject fields, those including general, physiological, perceptual and motor material have declined, while applied literature has increased. Citations from psychological and educational journals have increased; from other fields have remained steady or declined. German shows a spectacular decline, while English has increased at a similar rate." Graphic representations of the data for successive decades beginning with 1894 are presented. A check of the trends based upon content analysis of Ladd''s Elements of Physiological Psychology in 1887, the revision by Ladd and Woodworth in 1911, Woodworth''s Experimental Psychology in 1938, and Woodworth and Schlosberg''s Experimental Psychology in 1954 provides an independent source of data which verify the general trends indicated.
