In this bibliography the titles are classified in the same way as in the one of last year, except that we have added two new sections, one on rating scales and one on experiments which, though quantitative, do not involve tests. In addition to the titles of the year 1926 we have added a few that were omitted from the last report. General discussions are omitted unless they refer specifically to measurements or measuring techniques.A. Summaries. Summaries of special phases or parts of the field have been made by Brandenburg ( 14) on character analysis by means of certain structural measurements; by Cleeton ( 26) on originality; by Clara Chassell Cooper (27) on habit formation in character; by Dodge (33,34) on inhibition; by Yoakum and Manson (149) on self-ratings; by Barr (5) on measurement in civics; by Bingham (7) on personality traits pertaining to vocations; by Bingham and Freyd (8) on personality traits in industry. Wider ranges of titles are given in summaries by Haggerty (55) on scientific methods in character studies; by Leta S. Hollingworth (63) on character, temperament and interests of gifted children. Viteles (137) has a summary of psychology in industry; von Bracken (13) lists 120 titles, mostly German, on experimental techniques in studying character. The Committee on Character Education of the National Education Association (23) lists 153 titles on character study. Summaries adhering more rigidly to measurements are by May and Hartshorne (91), Watson (140), Whaley (146), Freeman (45) and Allport (3). A very complete bibliography including 1,364 titles and covering almost everything in the field is Manson's (89). B. Batteries Including Various Assemblages of Tests Intended to Measure More Than a Single Trait. Moss et al. (97,98,99) have produced a social intelligence test composed of six tests: memory for names and faces; judgment of

About thirty of the reports appearing in 1929 were based on new tests and techniques. Very little was written about ratings, but the use of controlled observation as a scientific instrument was indicated in eleven studies. There is an increasing tendency to use existing techniques for the solution of problems. That is, the center of interest is gradually shifting from tools to problems. The total number of articles is far smaller than for several years.Summaries. In addition to the writers' summary (71), Burnham (13), Fisher (27), Furfey (31), Sister McDonough (67), and Watson (115) provide lists of studies.Behaviors and Traits. Ratings and measures of groups of tendencies are reported by Decroly and Wauthier ( 22), Henning (47,48), Jordan (58), McClure (66), South and Clark (95), Steen and Huntington (98), Steere (99), and Vernon (111). Differences between identical twins in sundry traits were studied by Newman (78,79). Inferiority feelings and emotional instability are dealt with by Ball (3), and Gardner and Pierce (32).The Colgate inventories, Conklin's device, and the Freyd-Heidbreder list have been used in whole or in part in a variety of experiments by Broom (11), Brownell (12), Campbell (15), Estabrooks and Huntington (26), Garrett (33), Hovey (51), McClatchy (65), South and Clark (95), Weber and Maijgren (116), Wetmore and Estabrooks (117), and Whitman (120,121). New devices for measuring introversion-extroversion are reported by Newcomb (77), and Neymann and Kohlstedt (80).Oates (81) continues his studies of the Downey tests, and Harrell and Davis (40) discuss their application to institutional children. They appear also in Newman's studies of twins (78, 79), and Peterson and Lanier's (84) study of negroes and whites, and in a report by Richardson (92).Pressey's X-0 tests, the Woodworth questionnaire and the Kent-Rosanoff association tests were used by Newman (78, 79) ; Weber and Maijgren (116) included the X-0 and association tests in their battery; Dickinson (23) used the Woodworth-Mathews, Wood-485
