Review of Differential psychology (Rev. Ed.)

Abstract

Reviews the book entitled "Differential Psychology" by A. Anastasi and J. P. Foley (see record 1950-01528-000 ). Anastasi's 1937 Differential psychology is now enlarged by four new chapters covering the basic concepts of psychological testing, the biological and psychological factors in simple behavioral development, and the effects of schooling on intelligence. Other material, accrued since 1937, on trait organization and socio-economic differences has been added to the earlier discussion and is here reorganized into two substantially new chapters. Eighteen other chapters which conform closely to their former headings and sub-headings, have been re-written to include researches of more recent date. Outstanding inter-disciplinary contributions are certain studies from genetics, anthropology, and sociology. The book is divided to orient the reader historically and methodologically, to present an analysis of individual differences, and then to discuss group differences. Studies from sociology and anthropology are integrated with research in psychology to give a larger perspective on common problems. This second edition reflects a more studied consideration of content and aptness of expression, and shows growth in unraveling theoretical complexities. The new edition affords a useful compendium for professional workers and students who cannot themselves read, digest, and coordinate original research publications. The main service of this book, however, is in the training it gives in being alert for "common pitfalls and sources of error in interpretation of obtained results," with the authors repeatedly puncturing conclusions drawn from insufficient data, unreliable tests, poorly designed research experimentation, ineffective controls, inadequate statistical treatment, or just plain immaturity of psychological understanding. This second edition is well documented, well illustrated, well arranged, and well written. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
