Contributors to the volume represent an international "who's who" of research scientists from the fields of psychology and measurement. It offers the insights of these leading authorities regarding cognition and personality. In particular, they address the roles of constructs and values in clarifying the theoretical and empirical work in these fields, as well as their relation to educational assessment. It is intended for professionals and students in psychology and assessment, and almost anyone doing research in cognition and personality.

The Family System Test (FAST), developed by Thomas M. Gehring, is an important new tool for investigating family relations. Based on the structural-systemic theory of families, it is a figural technique for representing emotional bonds (cohesion) and hierarchical structures in the family or similar social systems. In this unique volume, the editors draw on current theory and research in family or similar social systems together with a variety of empirical studies that have used the FAST, to provide a comprehensive overview and assessment of the test and its use in various clinical research contexts.
The book is divided into four sections, each focusing on a different aspect of the FAST. Part 1 describes the concepts and psychometric properties of the FAST within the context of theoretically and empirically relevant aspects of the field of family psychology as a whole. Special emphasis is given to systematic-structural approaches to assessing individual and family functioning. Part II focuses on the use of the FAST in developmental research. For example, the the FAST has been used to show how family constructs are influenced by age, type of family and situation. Part III deals with cross-cultural issues and compares the interpersonal constructs of Japanese and Chinese families to Western families. Finally, Part IV addresses the applications of the FAST in clinical setting - in diagnosis of biopsychosocial problems and planning and evaluation of clinical interventions.
The result is a book that helps to bridge the gap between theory, practice and research. It will be essential reading for users of the FAST and all clinicians and researchers who work in family relations and development.

Selection for secondary education at 11-plus still arouses widespread controversy; and the psychological techniques which are employed, such as intelligence and attainments tests, are often criticised. Originally published in 1957, under the auspices of the British Psychological Society, a group of psychologists, experienced in this field, tried to present a balanced survey of the situation at the time. They show that the real problems of secondary schooling cannot be solved by simple administrative changes; they arise from historical causes, from the class structure of English society and the educational and vocational ambitions of parents. Psychology has studied the development and differentiation of children's abilities and interests with age, and thus throws light on the need for, and the consequences of, streaming children in different classes or schools, and the value of alternative systems such as the comprehensive school. Selection at 11-plus, it is admitted, does have harmful effects on teaching in the junior school and produces much emotional strain, though these effects are often exaggerated. It was, in fact, accurate for some ninety per cent of children; yet the implications of its inevitable inaccuracy for some pupils cannot be ignored. The functions, and the value, of intelligence and attainments tests and the essay are examined, and full consideration given to the use of teachers' estimates of suitability and other techniques. The Report is addressed primarily to teachers, educational administrator, and psychologists - that is people with some background knowledge of the problems involved; but it should also be intelligible and helpful to the educated layman, since the more technical details are confined to Appendices.

Stanley Milgram's experiments on obedience to authority are among the most important psychological studies of this century. Perhaps because of the enduring significance of the findings--the surprising ease with which ordinary persons can be commanded to act destructively against an innocent individual by a legitimate authority--it continues to claim the attention of psychologists and other social scientists, as well as the general public. The study continues to inspire valuable research and analysis. The goal of this book is to present current work inspired by the obedience paradigm.
This book demonstrates the vibrancy of the obedience paradigm by presenting some of its most important and stimulating contemporary uses and applications. Paralleling Milgram's own eclecticism in the content and style of his research and writing, the contributions comprise a potpourri of styles of research and presentation--ranging from personal narratives, through conceptual analyses, to randomized experiments.

Ivan P. Pavlov was a pioneering Russian physiologist whose influence on Russian psychology was politically emphasized in 1930s to 1950s. He was a brilliant experimenter who received 1904 Nobel Prize in Physiology or Medicine for his work on the digestive system. Less is known about his epistemology of generalization that made it possible to study one individual for the sake of obtaining generalized knowledge. In this volume we analyze the major contributions of Pavlov from the standpoint of idiographic science, and demonstrate how generalizations in science are possible from single specimens.

Cognitive task analysis is a broad area consisting of tools and techniques for describing the knowledge and strategies required for task performance. Cognitive task analysis has implications for the development of expert systems, training and instructional design, expert decision making and policymaking. It has been applied in a wide range of settings, with different purposes, for instance: specifying user requirements in system design or specifying training requirements in training needs analysis. The topics to be covered by this work include: general approaches to cognitive task analysis, system design, instruction, and cognitive task analysis for teams. The work settings to which the tools and techniques described in this work have been applied include: 911 dispatching, faultfinding on board naval ships, design aircraft, and various support systems.
The editors' goal in this book is to present in a single source a comprehensive, in-depth introduction to the field of cognitive task analysis. They have attempted to include as many examples as possible in the book, making it highly suitable for those wishing to undertake a cognitive task analysis themselves. The book also contains a historical introduction to the field and an annotated bibliography, making it an excellent guide to additional resources.

This book offers a comprehensive introduction to the latest developments in the theory and practice of CAT. It can be used both as a basic reference and a valuable resource on test theory. It covers such topics as item selection and ability estimation, item pool development and maintenance, item calibration and model fit, and testlet-based adaptive testing, as well as the operational aspects of existing large-scale CAT programs.

The primary purpose of this revision remains identical to that of the first edition--to show how key personality, cognitive/behavioral, and vocational tests/assessment procedures can be used by counselors in their work with clients. Too often, assessment books only provide the reader with information about tests and assessment procedures. They do not, however, take the next step--showing readers how these tests/assessment procedures can be used and integrated into the actual work of counseling. This revision is designed to fill that void. Chapter authors, all of whom are experts in their respective topic areas, share the theoretical and research backgrounds about a particular test/assessment procedure and then provide a case example or examples to show how assessment data can be meaningfully incorporated into the counseling process.

The self psychology of Heinz Kohut has been an important force in contemporary psychoanalytic thought and its ramifications for therapy have been extensively explored. Now, Marshall Silverstein offers the first analysis of the application of self psychology to projective diagnostic assessment. Differentiating the self psychological approach from an ego psychological interpretation of classical drive theory, he clearly outlines the principal contributions of Kohut, including the concepts of selfobject functions, empathy, transmuting internalization, and compensatory structure. Providing numerous clinical examples, he shows how the major selfobject functions of mirroring, idealization, and twinship can be identified on projective tests. Silverstein then demonstrates how conventional assessment approaches to grandiosity, self-esteem, and idealization can be reconceptualized within the framework of self psychology, and he also contrasts ego psychological interpretations with self psychological interpretations.
This book makes a strong case for the importance of the clinical identification of self states. It will help practitioners understand their patients' varied attempts to repair an injury to the self to restore self-esteem (compensatory structure) and the clinical consequences of self-disorders, including disintegration products such as narcissistic rage and affect states characterized by empty depression, chronic boredom, and lack of zest.

"Validation in Language Assessment" contributes to the variety of validation approaches and analytical and interpretive techniques only recently adopted by language assessment researchers. Featuring selected papers from the 17th Language Testing Research Colloquium, the volume presents diverse approaches with an international perspective on validation in language assessment.

In today's "trial by media" election campaigns, do you have to be crazy to run for higher office? Looking back over the past 25 years, Stanley Renshon provides the first comprehensive account of how the issue of character has come to dominate presidential campaigns. He traces two related but distinctive approaches to a candidate's psychology: mental health and character. Drawing on his clinical and political science training, Renshon has devised a theory which will allow the public to better evaluate the personal and leadership qualities of presidential candidates.

This book describes the evolution of the Washington University Sentence Completion Test (SCT), a major measure of ego development, from an intuitive rating scale to an empirically derived reliable and valid personality test. The authors recount the complete history of the SCT, which begins with the Family Problems Scale, an objective test of mothers' attitudes. Work with that test led to a concept of ego development, testable by the SCT, which was elaborated and refined in further work.
The book discusses uses of the SCT in other languages and other cultures, offers suggestions for giving the SCT in translation, and presents computer programs for handling SCT responses. Data on reliability and validity of the SCT are brought up to date. These include evidence of the equivalence of the male and female forms of the current version, Form 81, and the equivalence of the two halves of Form 81, each usable as a short form. Rules for obtaining total protocol ratings for 18-item as well as 36-item forms are given. Frequently used forms of the SCT, including a new form for adolescents and children over eight years old, are presented.

There have been many important changes in the participation of women and men in American society over the past quarter-century. Tests play a role in those changes by providing evidence of the diverse achievement and proficiency of women and men. They aid the learning process and reflect inequalities in opportunity to learn and participate. In addition, they provide useful information in considering what alternatives in education and work make most sense for individuals and influence views about groups of students, educational programs, and a wide range of issues. For all of these reasons, it is important that tests assess fairly and reflect accurately the ways young people are and are not achieving as well as desired.
The test performance of women and men is a research topic of historical interest and has received much attention in recent years. Because of this increased interest, there is a great deal of new research and data available. The purpose of the study presented in this volume was to review this new information with two objectives in mind:
*to clarify patterns of gender difference and similarity in test performance and related achievements, and
*to see what implications those findings might have for fair assessment and, as a corollary, examine the assessment process as a possible source of gender differences.
This study is interested in tests used in education to assess developed knowledge and skill. In order to gain a broader view of gender similarity and difference, the contributors looked at other types of measures and other characteristics of young women and men. Their hope is to contribute to a firmer basis for insuring fairness in tests--an objective which is particularly important as the field moves increasingly to new forms of assessment in which there is less experience.

This book offers clinicians a long-awaited comprehensive paradigm for assessing object relations functioning in disturbed younger and older adolescents. It gives a clear sense of how object relations functioning is manifest in different disorders, and illuminates how scores on object relations measures are converted into a therapeutically relevant diagnostic matrix and formulation.
Outlining the process of object relations assessment, Kelly presents vividly detailed cases of a range of disorders including anorexia nervosa, borderline states, depressive disorders, and trauma. The cases portray the vicissitudes of object relations functioning and disruption that result in a unique structural developmental composite for a given adolescent.
A major concern is demonstrating the utility and validity of two object representation measures--The Mutuality of Autonomy Scale (MOA) and The Social Cognition Object Relations Scale (SCORS)--that are the main ones employed in the assessment of adolescents. MOA and SCORS scores facilitate a multidimensional understanding of the nuances of an adolescent's object relations functioning, and provide clinicians with organized, theory-based data leading to clear, specific treatment directions and guidelines and appropriate therapeutic programming. The book addresses the following questions:
* Is individual psychotherapy indicated--will this adolescent benefit from an insight-oriented approach?
* What are the likely directions that transference parameters will take in the treatment?
* What types of countertransference reactions are likely to be anticipated in a given patient?
* Is medication likely to be helpful in making this adolescent more accessible for treatment?
Focusing only on adolescents, covering both the TAT and the Rorschach, and utilizing object relations theory as its major interpretive foundation, the book offers practitioners an alternative to general references based on a more actuarial, nomothetic, and atheoretical interpretive approach. It reflects one school of contemporary thought in projective assessment--one that advocates a more phenomenological, theory-based approach to test application and interpretation.

Appreciation of the beauty and complexity of the human mind when perceiving an ambiguous stimulus led Dr. Hermann Rorschach to develop his scientific method eighty years ago. Full of gratitude for his brief life and work, the editors hope this volume will stand as an idiographic testament to his brilliance for the Rorschach students of the future. The contributors are clearly the most notable Rorschach clinicians in practice, and their work integrates the Comprehensive System and psychoanalytic methods.
This book is organized into four sections. Within each of the first three sections -- devoted to psychotic, borderline, and neurotic disorders respectively -- the editors and invited authors have contributed Rorschach case studies which vertically cut a character pathology, personality disorder, or clinical diagnosis through a particular level of personality organization. The last section charts the enormously varied course that Rorschach work can navigate -- from the understanding of a Nobel laureate, the pain of trauma and transexuality, and the Nazi perversion of youth, to the consensus Rorschach in couple's therapy and cutting edge work in neuropsychology.

Psychodiagnosis in Schizophrenia is a reprint of a classic volume in assessment psychology that first appeared in 1966. The book concerns the use of psychodiagnostic techniques in the differential diagnosis of schizophrenia. The author first presents a conceptual analysis of schizophrenic disturbance in terms of impaired ego functioning and extrapolates from schizophrenic ego impairments to psychodiagnostic indices that have been demonstrated to assess them. In particular, Weiner refers to the Wechsler Adult Intelligence Scale, the Rorschach Inkblot Method, and the Draw-A-Person test. Clinical and research data delineating the nature of psychological deficits in schizophrenia are reviewed, and practical guidelines for the clinical assessment of these deficits are presented.
The author next considers several differential diagnostic possibilities frequently considered in the evaluation of schizophrenic persons, with separate chapters devoted to the many forms of schizophrenia, such as: acute, chronic, paranoid, nonparanoid, incipient, remitting, borderline and pseudoneurotic. There are also chapters that focus on schizoaffective disorder and adolescent schizophrenia. The conceptual and empirical contributions to these distinctions are reviewed; accordingly, the differentiating characteristics of these subcategories are related to parameters of psychodiagnostic test performance. In additon, the process of differential psychodiagnosis in schizophrenia is illustrated by detailed case studies. In an extended new preface, the author comments on current perspectives and contemporary literature related to the individual chapters of the text.

Pain is an unfortunate daily experience for many individuals. Chronic pain -- lasting six or more months -- is suffered by approximately 30% of the population in the United States. These individuals wake up, function during the day and go to sleep, trying to keep pain at a minimum while, at the same time, maintaining some quality of life. They may make frequent visits to the doctor and the pharmacy. When they find relief, it is usually short-lived and comes at a cost such as dependence on narcotic medications or complete limitation of activity. Pain often becomes the central point of their existence.
This practice guide describes an approach to psychological evaluation of the chronic pain patient who is being considered for surgery. A large body of research is accumulating which demonstrates that the outcome of surgical procedures aimed at chronic pain relief can be strongly influenced by psychological and emotional factors. This approach, termed "presurgical psychological screening" (PPS) uses interview and testing techniques to identify emotional, behavioral, and psychosocial difficulties which have been demonstrated to negatively impact surgical outcome. Studies show that even patients with clearly identifiable pathophysiology may respond poorly to surgery, due to issues such as pain sensitivity, medication dependence, rewards for pain behavior and personality style. Thus, some insurance carriers, rehabilitation nurses and state worker's compensation systems are encouraging, or even requiring, presurgical psychological screening in cases of surgery designed to relieve chronic pain.
The first to present a comprehensive, unified approach to PPS in chronic pain syndromes, this text is designed to provide the behavioral health practitioner, as well as the trainee, with all the tools and information necessary to conduct PPS evaluations. It identifies a multitude of risk factors for poor surgical outcome and reviews research associated with each risk factor. Hands-on techniques for eliciting information from the patient about risk factors is also detailed. Toward this end, the practice guide also contains a number of forms and session outlines which can be directly utilized, or which can be altered to fit readers' needs. Models for weighing and combining surgical outcome risk factors are also provided. Thus, practitioners are able to reach valid and reliable predictions of surgical results. Finally, the text provides outlines of psychological interventions which can facilitate surgical outcome as well as surgical treatment alternatives. Upon completion of this practice guide, readers should be able to begin providing PPS evaluations which are scientifically valid, clinically sound, and which result in significant overall improvement in the treatment of chronic pain syndromes.

The Minnesota Multiphasic Personality Inventory (MMPI, MMPI-2, and MMPI-A) and the Rorschach are the two tests used most widely in clinical personality assessment to evaluate personality functioning, current emotional state, and the presence, nature, and severity of psychopathology, as well as to formulate treatment interventions. Psychologists' vigorous interest in and intense loyalty to the Rorschach and MMPI are reflected in the large and still growing theoretical and empirical literature concerning these tests. Given the enduring popularity of these two tests, it is surprising to find that only a small percentage of these numerous studies have examined the relationships between the two.
Both tests provide valuable information about an individual's symptoms, behavior, emotions, interpersonal functioning, self-concept, defenses, and the dynamics underlying their behavior. Although much has been written about each test individually, little has been written about how to use the two tests together even though many psychologists use a battery of tests when conducting personality assessments in clinical practice. The basic premise of this book is that psychologists' armamentarium of assessment techniques can be strengthened by using the MMPI-2 and Rorschach together in a complementary fashion, and that essential information may be lost if one test is used to the exclusion of the other.
The book examines interrelationships between the MMPI-2 and Rorschach on several different levels including empirical and research findings, conceptual relationships, and integrated interpretations using a series of in-depth case presentations. A balance is maintained between the foundation provided by research and by clinical theory for conceptualizing, understanding, and treating patients with a variety of psychological disorders. This volume illustrates the contribution psychological test findings make to clinical decision making and differential diagnosis, and discusses the links between test data, clinical judgment, and DSM-IV.

Quickly acquire the knowledge and skills you need to confidently administer, score, and interpret the most popular neuropsychological assessment instruments

Neuropsychological testing can identify changes in cognition, behavior, and emotion; aid in determining the cause of a disorder or developmental problem; and assist clinicians in planning treatment and rehabilitation. To use these tests properly, professionals need an authoritative source of advice and guidance on how to administer, score, and interpret them. Now fully revised and in a second edition, "Essentials of Neuropsychological Assessment" is that source.

Completely updated to include the most current instruments, including the Delis-Kaplan Executive Function System (D-KEFS), the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV), the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV), and the Wechsler Memory Scale-Fourth Edition (WMS-IV), Essentials of Neuropsychological Assessment, Second Edition presents an overview of the assumptions, logic, knowledge base, and skills underlying the practice of neuropsychological assessment. Neuropsychological experts Nancy Hebben and William Milberg describe how clinical history, behavioral observations, and formal test results are used to make inferences about the contribution of brain dysfunction to psychological functioning.

Like all the volumes in the Essentials of Psychological Assessment series, this book is designed to help busy mental health professionals quickly acquire the knowledge and skills they need to make optimal use of major neuropsychological assessment instruments. Each concise chapter features numerous callout boxes highlighting key concepts, bulleted points, and extensive illustrative material, as well as test questions that help you gauge and reinforce your grasp of the information covered.

"Essentials of Neuropsychological Assessment," Second Edition provides comprehensive instruction on neuropsychological test administration, scoring, interpretation, and report writing.

Any research that involves the use of the Rorschach or focuses on the nature of the Rorschach must be framed in the context of the basic principles that mark any scientific investigation. However, most texts concerning research design or data analysis do not deal directly with many of the unusual issues that confront investigators who use the Rorschach in their research. The nature of the test and test procedures are somewhat different than for most psychological tests, and, often, these special characteristics become critical when research designs are formulated. Similarly, some of the data of the tests are quite different from the customary distributions yielded by other psychological tests. Thus special care must be exercised when considering the variety of tactics that might might be used in analyzing the test data.
This text is unique in that it is specific to the Rorschach. Bringing together experts on Rorschach research, this volume presents in-depth treatments of every facet of methodology -- from design to analysis -- as well as more conceptual issues. It is designed to aid investigators in contending effectively with the many difficult challenges that are often encountered in Rorschach research.
This work adds to the information already available to the accomplished researcher as well as provide some enlightenment for the Rorschach research novice. It dispels the notion that rote methodology or analyses can be applied routinely to studies involving the Rorschach. And it helps to improve the quality of investigations in which the test is included, and contribute in some way to the improvement of the overall research yield in the Rorschach community.

Half a century after the collapse of the Nazi regime and the Third Reich, scholars from a range of fields continue to examine the causes of Nazi Germany. An increasing number of young Americans are attempting to understand the circumstances that led to the rise of the Nazi party and the subsequent Holocaust, as well as the implication such events may have for today as the world faces a resurgence of neo-Nazism, ethnic warfare, and genocide.
In the months following World War II, extensive psychiatric and psychological testing was performed on over 200 Nazis in an effort to understand the key personalities of the Third Reich and of those individuals who "just followed orders." In addressing these issues, the current volume examines the strange history of over 200 Rorschach Inkblot protocols that were administered to Nazi war criminals and answers such questions as:
* Why the long delay in publishing protocols?
* What caused such jealousies among the principals?
* How should the protocols be interpreted?
* Were the Nazis monsters or ordinary human beings?
This text delivers a definitive and comprehensive study of the psychological functioning of Nazi war criminals -- both the elite and the rank-and-file. In order to apply a fresh perspective to understanding the causes that created such antisocial behavior, these analyses lead to a discussion within the context of previous work done in social and clinical psychology. Subjects discussed include the authoritarian personality, altruism, obedience to authority, diffusion of responsibility, and moral indifference. The implications for current political events are also examined as Neo-Nazism, anti-Semitism, and ethnic hate are once again on the rise. While the book does contain some technical material relating to the psychological interpretations, it is intended to be a scholarly presentation written in a narrative style. No prior knowledge of psychological testing is necessary, but it should be of great benefit for those interested in the Rorschach Inkblot test, or with a special interest in psychological testing, personality assessment, and the history of psychology. It is also intended for readers with a broad interest in Nazi Germany.

During the past two or three decades, research in cognitive science and psychology has yielded an improved understanding of the fundamental psychological nature of knowledge and cognitive skills that psychological testing attempts to measure. These theories have reached sufficient maturity, making it reasonable to look upon them to provide a sound theoretical foundation for assessment, particulary for the content of assessments. This fact, combined with much discontentedness over current testing practices, has inspired efforts to bring testing and cognitive theory together to create a new theoretical framework for psychological testing -- a framework developed for diagnosing learners' differences rather than for ranking learners based on their differences.
This volume presents some initial accomplishments in the effort to bring testing and cognitive theory together. Contributors originate from both of the relevant research communities -- cognitive research and psychometric theory. Some represent collaborations between representatives of the two communities; others are efforts to reach out in the direction of the other community. Taking fundamentally different forms, psychometric test theory assumes that knowledge can be represented in terms of one or at most a few dimensions, whereas modern cognitive theory typically represents knowledge in networks -- either networks of conceptual relationships or the transition networks of production systems.
Cognitively diagnostic assessment is a new enterprise and it is evident that many challenging problems remain to be addressed. Still, it is already possible to develop highly productive interactions between assessment and instruction in both automated tutoring systems and more conventional classrooms. The editors hope that the chapters presented here show how the reform of assessment can take a rigorous path.
