Psychology is a broad, exciting field. Psychologists work in settings ranging from schools and clinics to basic research laboratories, pharmaceutical firms, and private international companies. Despite this diversity, all psychologists have at least two things in common: They all study behavior, and they all depend to some extent on its measurement. This book concerns a particular type of measurement, psychological tests, which measure characteristics pertaining to all aspects of behavior in human beings.
Psychological Testing is the result of a long-standing partnership between the authors. As active participants in the development and use of psychological tests, we became disheartened because far too many undergraduate college students view psychological testing courses as boring and unrelated to their goals or career interests. In contrast, we see psychological testing as an exciting field. It has a solid place in the history of psychology, yet it is constantly in flux because of challenges, new developments, and controversies. A book on testing should encourage, not dampen, a student's interest. Thus, we provide an overview of the many facets of psychological tests and measurement principles in a style that will appeal to the contemporary college student.
To understand the applications and issues in psychological testing, the student must learn some basic principles, which requires some knowledge of introductory statistics. Therefore, some reviewing and a careful reading of Part I will pave the way for an understanding of the applications of tests discussed in Part II. Part III exam-ines the issues now shaping the future of testing. Such issues include test anxiety, test bias, and the interface between testing and the law. The future of applied psychology may depend on the ability of psychologists to face these challenging issues.
Throughout the book, we present a series of focused discussions and focused examples. These sections illustrate the material in the book through examples or provide a more detailed discussion of a particular issue. We also use box features called “Psychological Testing in Everyday Life" to demonstrate material such as statistical calculations. -- Preface
