doi: 10.1037/h0063637pmid: N/A
The authors review experiments in which Fisher's experimental designs are used, explain why these designs are valuable, and indicate some of the situations in which analysis of variance techniques offer a more efficient method of attacking problems than techniques currently in use. The article includes discussions of the Latin Square; the Greco-Latin Square; factorial methods; analysis of covariance; and the applications of analysis of variance to reliability of mental tests, to test for linearity of regression, to the standard error of an obtained score, and to item selection and validation. Bibliography of 48 titles.

Many of those with unfavorable attitudes had strong attitudes about deprivation and fears about war. There was more criticism and verbalization among older youths.

Review of 'The rat in laboratory investigation'Anderson, John E.
doi: 10.1037/h0053370pmid: N/A
Reviews the book The rat in laboratory investigation. Almost twenty years ago Dr. H. H. Donaldson, a member of the Wistar Institute, published his book, The Rat That book was an almost indispensable reference book for anyone dealing with this animal in the laboratory. The present book, which bears many earmarks of the same Institute, is just as indispensable. The indispensability of the two books rests, however, upon different foundations. Dr. Donaldson's book is largely a book of norms of growth and development of the rat while the present manual is concerned chiefly with techniques of handling and studying the animal. The raison d'etre of this manual is largely the tremendous use of the albino rat as a laboratory animal. No other species is so widely used. The mechanics of the book are excellent. It is well printed, and glossy paper is used because of the presence of so many half-tones. It is bound in sturdy binding which looks as if it would stand being wiped off occasionally with a damp cloth. Thus, one may feel free to have the book at one's elbow in the laboratory. The present reviewer can find no significant adverse criticism. His opinion is that this book is a necessity for any experimenter or laboratory using the rat.
