Paul Kline's book provides a modern, readable introduction to the psychometry of intelligence. It explains factor analysis and the construction of intelligence tests and shows how the resulting factors provide a picture of human abilities. `... an interesting and well written book which might well form the basis of a course on intelligence. It is well organized, reviews nost of the relevant evidence, and might be regarded for the most part as embodying a consensus of experts in the field.' - H.J. Eysenck
