An Introduction To the Logic of Psychological Measurement
This book declines to take for granted the widespread assumption that existing psychometric procedures provide scientific measurement. The currently fashionable concepts of measurement within psychology -- operationalism and representationalism -- are critically examined, and the classical view, that measurement is the assessment of quantity, is defended. Within this framework, it is shown how conjoint measurement can be used to test the hypothesis that variables are quantitative. This theme is developed in detail using familiar psychological examples, such as Thurstone's law of comparative judgment, multidimensional scaling, and Coombs' theory of unfolding.

An Introduction to Psychological Assessment and Psychometrics
Electronic Inspection Copy available for instructors here A good understanding of the foundations of psychological assessment and measurement is central to both applied and theoretical psychology. Having many years experience as an applied psychologist, trainer and university lecturer, Keith Coaley outlines in an accessible way the key ingredients of psychological assessment, providing case studies to illustrate their application, making it an ideal textbook for courses on psychometrics or psychological assessment. Case studies demonstrate the variety of contexts in which assessment is conducted. With their help readers will be able to prepare for professional practice using the wide variety of test materials available in the modern world. The book covers the nature of assessment, basic components, how tests are made, underlying statistics, reliability and validity, assessment of intelligence, abilities and personality, non-psychometric approaches, as well as ethical and professional issues and modern developments. A final chapter explains how readers can construct their own tests.
