‘This is a well-balanced, lively, very readable, fair-minded book…. Owing to its charity and sanity, it will be appreciated by a very wide variety of readers. It is probably the most useful book on intelligence to appear for at least a decade.’ –Alice Heim, British Journal of Psychology‘His style is refreshingly free from the jargon that disfigures so much contemporary writing in the field of education. Throughout the volume his discussion of the complex problems with which he deals is admirably eclectic and impartial, and always linked to practical issues current at the present day. It is book that should be read by every student of psychology or education, and by every educational psychologist who wishes to bring himself up to date.’- Sir Cyril Burt, British Journal of Educational Psychology‘…...a standard text for all those seeking a sound introduction to this area.’- P. L. Broadhurst, British Journal of Psychiatry
