doi: 10.1037/h0056546pmid: 20256568
The purpose of this study was to determine whether there was any relation between the verbal expressions of the members of a therapy group and the value which they received from such therapy, and to discover whether processes similar to those of individual psychotherapy occurred in the group. The "benefited" group showed a great increase in the number of "therapeutic" statements and exhibited a therapeutic pattern similar to that of nondirective individual therapy. Eleven further findings are discussed.
Methods of studying the progress and outcomes of a group psychotherapy programLuchins, Abraham S.
doi: 10.1037/h0062370pmid: 20256569
There is a need for controlled experimental methods in the domain of group psychotherapy, so that some clarification may be introduced concerning the actual outcomes and relative efficacy of various programs, the value of group therapy as opposed to individual therapy, and the role and function of the group. The author describes various preliminary methods which he used in conjunction with group psychotherapy programs in 2 Army hospitals. The purpose of the methods was to control the programs while they were in progress and to test their outcomes.
Color in the Rorschach and Kohs block designsSarason, Seymour B.; Potter, Elmer H.

Poor performance on the colored Kohs block designs is associated with the inability to respond constructively to the colored Rorschach cards. It is suggested that (1) the presence of color stimulates emotional reactions which interfere with the intellectual functioning, or (2) the presence of colors makes the visual grasp of figure-ground relationships difficult and results in emotional reactions which make for inefficient intellectual functioning.

Reviews the book, The AAF qualifying examination by Frederick B. Davis (Ed.) (1947). The reviewer reports that the AAF Qualifying Examination is a printed test used for the initial screening process in air crew selection that was given to over a million men from 1942 to 1946. According to the reviewer, this report describes the successive forms of the examination, the principles and techniques underlying its construction, and the data concerning the types of test items used: verbal, information, judgment and reasoning, mechanical, perceptual, and others.
Review of 'Multiple-factor analysis'Shaffer, Laurance F.
doi: 10.1037/h0053304pmid: N/A
Reviews the book, Multiple-factor analysis by L. L. Thurstone (1947). The reviewer reports that this book was initially intended as a revision of Vectors of Mind (1935), but this volume grew into an expanded treatise on the theory, rationale, and operations of factor analysis. Many of the controversial issues of the earlier volume are clarified by the more extended treatment; this is especially true of the concepts of simple structure, communality, and the rotation of axes. According to the reviewer, the book's logic is as impressive as its mathematics, and many parts of it contribute to the theory of experimental design, as well as to the more specific area of factor analysis. Although it can hardly be recommended to a reader without mathematical training, the clarity of presentation is remarkable, and the book is as readable as can be conceived in so symbolic a subject. The book includes a mathematical introduction of fifty pages reviews the basic concepts and symbols used, and can serve as a refresher or as a source of reference. The work is entirely theoretical; no applications to psychological problems are given, as these are covered by other references. Lastly, the reviewer states that this volume will become an indispensable guide for research workers using factor analysis, and a valuable textbook for advanced students.
