High stakes tests are the gatekeepers to many educational and professional goals. As such, the incentive to cheat is high. This Handbook is the first to offer insights from experts within the testing community, psychometricians, and policymakers to identify and develop best practice guidelines for the design of test security systems for a variety of testing genres. Until now this information was scattered and often resided inside testing companies. As a result, rather than being able to learn from each other's experiences, each testing entity was left to re-create their own test security wheel. As a whole the book provides invaluable insight into the prevalence of cheating and "best practices" for designing security plans, training personnel, and detecting and investigating misconduct, to help develop more secure testing systems and reduce the likelihood of future security breaches. Actual case studies from a variety of settings bring to life how security systems really work. Examples from both domestic and international programs are provided. Highlights of coverage include:* Best practices for designing secure tests * Analysis of security vulnerabilities for all genres of testing * Practical cheating prevention and detection strategies * Lessons learned in actual security violations in high profile testing programs. Part I focuses on how tests are delivered for paper-and-pencil, technology-based, and classroom testing and writing assessment. Each chapter addresses the prevalence of the problem and threats to security, prevention, and detection. Part II addresses issues essential to maintaining a secure testing program such as planning and monitoring, physical security, the detection of group-based cheating, investigating misconduct, and communicating about security-related issues. Part III examines actual examples of cheating-- how the cheating was done, how it was detected, and the lessons learned. Part III provides insight into security issues within each of the Association of Test Publishers' four divisions: certification/licensure, clinical, educational, and industrial/organizational testing. Part III's conclusion revisits the issues addressed in the case studies and identifies common themes. Intended for organizations, professionals, educators, policy makers, researchers, and advanced students that design, develop, or use high stakes tests, this book is also ideal for graduate level courses on test development, educational measurement, or educational policy.

A SPECTATOR BOOK OF THE YEAR 'History that reads like biography that reads like a novel - a fluid narrative that defies expectations and plays against type' New York Times 'Brilliant and savage' Philip Hensher An unprecedented history of the personality test conceived a century ago by a mother and her daughter - fiction writers with no formal training in psychology - and how it insinuated itself into our boardrooms, classrooms, and beyond. The Myers-Briggs Type Indicator is the most popular personality test in the world. It has been harnessed by Fortune 100 companies, universities, hospitals, churches, and the military. Its language - of extraversion vs. introversion, thinking vs. feeling - has inspired online dating platforms and Buzzfeed quizzes alike. And yet despite the test's widespread adoption, experts in the field of psychometric testing, a $500 million industry, struggle to account for its success - no less validate its results. How did the Myers-Briggs insinuate itself into our jobs, our relationships, our internet, our lives? First conceived in the 1920s by the mother-daughter team of Katherine Briggs and Isabel Briggs Myers, a pair of aspiring novelists and devoted homemakers, the Myers-Briggs was designed to bring the gospel of Carl Jung to the masses. But it would take on a life of its own, reaching from the smoke-filled boardrooms of mid-century New York to Berkeley, California, where it was honed against some of the 20th century's greatest creative minds. It would travel across the world to London, Zurich, Cape Town, Melbourne, and Tokyo; to elementary schools, nunneries, wellness retreats, and the closed-door corporate training sessions of today. Drawing from original reporting and never-before-published documents, What's Your Type? examines nothing less than the definition of the self - our attempts to grasp, categorise and quantify our personalities. Surprising and absorbing, the book, like the test at its heart, considers the timeless question: What makes you you?

The motivation for this volume in the History and Theory of Psychology series is to look across sub-disciplines within psychology and highlight instances where researchers transcended the tendency to think about methodology along traditional lines. Contributors have located examples of researchers who built upon existing ideas to create methods true to their interests and theoretical convictions.

Emerging Methods in Psychology shows how a discipline creates new methods and carves out possibilities that not only generate data, but also advance knowledge of human psychological functioning. It concentrates on showcasing the possibilities that exist when the researcher focuses on the relationship between theory, method, and data.

The question of what kind of expertise is required is a key issue. This is particularly the case in psychology where the tradition of standardizing methods over the last century has served to stabilize research questions. Knowledge creation is deeply affective and ambiguous rather than the secure accumulation of data by a socially legitimized procedure. This innovative volume moves beyond psychology as social engineering into new varieties of social knowledge.

This book describes a way of sharing dreams in a group, called 'social dreaming'. It explores how the sharing of real, night time dreams, in a group, can offer information on and insight into ourselves and the worlds we live in and share. It investigates how we can turn dream images, and ideas and feelings that arise from these images, into conscious thought, before describing the ways in which these can be used. Using a background of the psychosocial combined with a philosophical lens influenced by the work of Gilles Deleuze, Julian Manley shows how social dreaming can be understood as a Deleuzian 'rhizome of affects', a web or a root design where things interconnect in a random and spontaneous fashion rather than in a sequential or linear way. He illustrates how social dreaming can link dreams together into a collage of images, and compares this to the rhizome, where clusters of emotional intensity - which emerge from the dream images - weave and interconnect with other clusters, forming a web of interlinked dream images and emotions. From the basis of this rhizome emerges an interpretation of social dreaming as a 'body without organs' and the social dreaming matrix as a 'smooth space' where meanings emerge from the way these images form connections, and come and go according to our emotions at any particular moment.

This is the first workbook that introduces the multilevel approach to modeling with categorical outcomes using IBM SPSS Version 20. Readers learn how to develop, estimate, and interpret multilevel models with categorical outcomes. The authors walk readers through data management, diagnostic tools, model conceptualization, and model specification issues related to single-level and multilevel models with categorical outcomes. Screen shots clearly demonstrate techniques and navigation of the program. Modeling syntax is provided in the appendix. Examples of various types of categorical outcomes demonstrate how to set up each model and interpret the output. Extended examples illustrate the logic of model development, interpretation of output, the context of the research questions, and the steps around which the analyses are structured. Readers can replicate examples in each chapter by using the corresponding data and syntax files available at www.psypress.com/9781848729568. The book opens with a review of multilevel with categorical outcomes, followed by a chapter on IBM SPSS data management techniques to facilitate working with multilevel and longitudinal data sets. Chapters 3 and 4 detail the basics of the single-level and multilevel generalized linear model for various types of categorical outcomes. These chapters review underlying concepts to assist with trouble-shooting common programming and modeling problems. Next population-average and unit-specific longitudinal models for investigating individual or organizational developmental processes are developed. Chapter 6 focuses on single- and multilevel models using multinomial and ordinal data followed by a chapter on models for count data. The book concludes with additional trouble shooting techniques and tips for expanding on the modeling techniques introduced. Ideal as a supplement for graduate level courses and/or professional workshops on multilevel, longitudinal, latent variable modeling, multivariate statistics, and/or advanced quantitative techniques taught in psychology, business, education, health, and sociology, this practical workbook also appeals to researchers in these fields. An excellent follow up to the authors' highly successful Multilevel and Longitudinal Modeling with IBM SPSS and Introduction to Multilevel Modeling Techniques, 2nd Edition, this book can also be used with any multilevel and/or longitudinal book or as a stand-alone text introducing multilevel modeling with categorical outcomes.

Open Learning Units offer a very flexible approach to the teaching of psychology. They are designed to be more than sufficient for the purposes of A/S and A-Level psychology, and the applied emphasis will appeal to various vocational courses such as those offered by BTEC and also to mature students on Access courses.
Their primary use will be in the classroom with a tutor's guidance, but the interactive style makes them equally appropriate for the purposes of self-study. More advanced students might want to use the Units to learn at their own pace, and in all cases, the careful structure of the writing and the extensive use of Examples, Open Questions and Self-Assessment Questions make them ideal revision guides.

Now in its fourth edition, Behavioral Research and Analysis: An Introduction to Statistics within the Context of Experimental Design presents an overview of statistical methods within the context of experimental design. It covers fundamental topics such as data collection, data analysis, interpretation of results, and communication of findings. New in the Fourth Edition: Extensive improvements based on suggestions from those using this book in the classroom Statistical procedures that have been developed and validated since the previous edition Each chapter in the body now contains relevant key words, chapter summaries, key word definitions, and end of chapter exercises (with answers) Revisions to include recent changes in the APA Style Manual When looking for a book for their own use, the authors found none that were totally suitable. They found books that either reviewed the basics of behavioral research and experimental design but provided only cursory coverage of statistical methods or they provided coverage of statistical methods with very little coverage of the research context within which these methods are used. No single resource provided coverage of methodology, statistics, and communication skills. In a classic example of necessity being the mother of invention, the authors created their own. This text is ideal for a single course that reviews research methods, essential statistics through multi-factor analysis of variance, and thesis (or major project) preparation without discussion of derivation of equations, probability theory, or mathematic proofs. It focuses on essential information for getting a research project completed without prerequisite math or statistics training. It has been revised many times to help students at a variety of academic levels (exceptional high school students, undergraduate honors students, masters students, doctoral students, and post-doctoral fellows) across varied academic disciplines (e.g., human factors and ergonomics, behavioral and social sciences, natural sciences, engineering, exercise and sport sciences, business and management, industrial hygiene and safety science, health and medical sciences, and more). Illustrating how to plan, prepare, conduct, and analyze an experimental or research report, the book emphasizes explaining statistical procedures and interpreting obtained results without discussing the derivation of equations or history of the method. Destined to spend more time on your desk than on the shelf, the book will become the single resource you reach for again and again when conducting scientific research and reporting it to the scientific community. Illustrates how to plan, conduct, analyze, and prepare an experimental or research report Includes new statistical procedures that have been developed and validated since the previous edition Incorporates SAS in the exercises at the end of each chapter Takes into account the changes in the APA guidebook Provides new examples in exercise and sport science, public health, gerontology, and biomedical areas Solutions manual available upon qualifying course adoption

Chapters focus on summarising the current state of the art and its application with marginalised groups; analytic strategies for body mapping; highlighting body mapping as a creation and a dissemination process; emerging body mapping techniques including web-based, virtual reality, and wearable technology applications; and measuring the impact of body maps on planning, practice, and behaviour. Contributors and editors include interdisciplinary experts from the fields of psychology, sociology, anthropology, and beyond. Offering innovative ways of engaging in body mapping research, which result in real-world impact, this book is an essential resource for postgraduate students and researchers.

Although its roots can be traced to the 19th century, progress in the study of nonlinear dynamical systems has taken off in the last 30 years. While pertinent source material exists, it is strewn about the literature in mathematics, physics, biology, economics, and psychology at varying levels of accessibility. A compendium research methods reflecting the expertise of major contributors to NDS psychology, Nonlinear Dynamical Systems Analysis for the Behavioral Sciences Using Real Data examines the techniques proven to be the most useful in the behavioral sciences. The editors have brought together constructive work on new practical examples of methods and application built on nonlinear dynamics. They cover dynamics such as attractors, bifurcations, chaos, fractals, catastrophes, self-organization, and related issues in time series analysis, stationarity, modeling and hypothesis testing, probability, and experimental design. The analytic techniques discussed include several variants of the fractal dimension, several types of entropy, phase-space and state-space diagrams, recurrence analysis, spatial fractal analysis, oscillation functions, polynomial and Marquardt nonlinear regression, Markov chains, and symbolic dynamics. The book outlines the analytic requirements faced by social scientists and how they differ from those of mathematicians and natural scientists. It includes chapters centered on theory and procedural explanations for running the analyses with pertinent examples and others that illustrate applications where a particular form of analysis is seen in the context of a research problem. This combination of approaches conveys theoretical and practical knowledge that helps you develop skill and expertise in framing hypotheses dynamically and building viable analytic models to test them.

Practical Research with Children is designed to help the reader understand techniques for research with children, based on real world experience. The book describes a wide range of research methods, focusing equally on quantitative and qualitative approaches, and considers how different methods can be integrated. It highlights the benefits and challenges of each method and gives emphasis to best practice, with expert guidance on how to avoid potential pitfalls in order to obtain valuable insights into how children develop. The volume includes fifteen chapters arranged over three sections. Each chapter explores a particular method, or combination of methods, and discusses both theoretical and practical issues, using a diversity of domains, including different ages, cultures, populations and settings. Uniquely, the book includes newer methods (such as eye tracking and digital technologies) alongside well-established behavioural methods which are used for research with children. With contributions from internationally renowned researchers and practitioners from a range of disciplines, the book will be indispensable reading for a wide audience, including for students in psychology, education and nursing undertaking research projects with children, and also for anyone looking to understand the research behind current theories in child development.

This book explores how music can improve skills that are impaired in some neurodevelopmental disorders, including ADHD (attention deficit hyperactivity disorder), autism, and Rett syndrome. Rehabilitation interventions based on the use of music, termed "music therapy", are relatively widespread, but not all are supported by empirical evidence. This book offers readers an updated and scientifically grounded perspective on this theory and argues that music can be effective in promoting the acquisition of some basic mental abilities. Chapters present some of the latest research and data on how musical activities can lead children affected by neurodevelopmental disorders to improve those skills, including examples of training programs and exercises. The book will be a valuable resource for therapists, rehabilitators, psychologists, educators, musicians, researchers, as well as anyone interested in exploring the potential in music for human growth.

In treatment, the psychotherapist is in a position of power. Often, this power is unintentionally abused. While trying to embody a compassionate concern for patients, therapists use accepted techniques that can inadvertently lead to control, indoctrination, and therapeutic failure. Contrary to the stated tradition and values of psychotherapy, they subtly coerce patients rather than respect and genuinely help them. The more gross kinds of patient abuse, deliberate ones such as sexual and financial exploitation, are expressly forbidden by professional organizations. However, there are no regulations discouraging the more covert forms of manipulation, which are not even considered exploitative by many clinicians. In this book, noted psychiatrist Theo. L. Dorpat strongly disagrees. Using a contemporary interactional perspective Dorpat demonstrates the destructive potential of manipulation and indoctrination in treatment. This book is divided into three parts. Part I explores the various ways power can be abused. Part II examines eleven treatment cases in which covert manipulation and control either caused analytic failure or severely impaired the treatment process. Cases discussed include the analyses of Dora and the Wolf Man by Freud, the two analyses of Mr. Z by Kohut, as well as other published and unpublished treatments. An interactional perspective is used to examine the harmful short- and long-term effects of using indoctrination methods as well as to unravel conscious and unconscious communications between therapists and patients that can contribute to manipulations. Part III shows readers how to work using a non-directive, egalitarian approach in both psychoanalytic psychotherapy and psychoanalysis.

Foundations of Psychological Testing: A Practical Approach by Leslie A. Miller and Robert L. Lovler presents a clear introduction to the basics of psychological testing as well as psychometrics and statistics.

Scale Development: Theory and Applications, by Robert F. DeVellis and new co-author Carolyn T. Thorpe, demystifies measurement by emphasizing a logical rather than strictly mathematical understanding of concepts. The Fifth Edition includes a new chapter that lays out the key concepts that distinguish indices from scales, contrasts various types of indices, suggests approaches for developing them, reviews validity and reliability issues, and discusses in broad terms some analytic approaches. All chapters have been updated, and the book strikes a balance between including relevant topics and highlighting recent developments in measurement while retaining an accessible, user-friendly approach to the material covered.

This book explores the practice and transmission of Lacanian and Freudian theory. It discusses the pure versus applied analysis of Lacanian and Freudian theory in practice; and the hierarchical versus circular transmissions within psychoanalytic organizations. Underpinned by extensive practical knowledge of the clinic, this work examines the differences between Freud and Lacan in their understanding of the subject and the unconscious and pushes them in new directions. The book also offers an analysis and commentary of several key Lacanian texts including an accessible study of the notoriously challenging text L'etourdit. Offering both divergent and reinforcing takes on Lacan, the author explores the traits that separate out the psychoanalyst from other twentieth-century thinkers and theorists. This book offers a clear clinical picture of where Lacanian psychoanalysis is today, both in the US and internationally.

Emphasizing causation as a functional relationship between variables that describe objects, Linear Causal Modeling with Structural Equations integrates a general philosophical theory of causation with structural equation modeling (SEM) that concerns the special case of linear causal relations. In addition to describing how the functional relation concept may be generalized to treat probabilistic causation, the book reviews historical treatments of causation and explores recent developments in experimental psychology on studies of the perception of causation. It looks at how to perceive causal relations directly by perceiving quantities in magnitudes and motions of causes that are conserved in the effects of causal exchanges.

The author surveys the basic concepts of graph theory useful in the formulation of structural models. Focusing on SEM, he shows how to write a set of structural equations corresponding to the path diagram, describes two ways of computing variances and covariances of variables in a structural equation model, and introduces matrix equations for the general structural equation model. The text then discusses the problem of identifying a model, parameter estimation, issues involved in designing structural equation models, the application of confirmatory factor analysis, equivalent models, the use of instrumental variables to resolve issues of causal direction and mediated causation, longitudinal modeling, and nonrecursive models with loops. It also evaluates models on several dimensions and examines the polychoric and polyserial correlation coefficients and their derivation.

Covering the fundamentals of algebra and the history of causality, this book provides a solid understanding of causation, linear causal modeling, and SEM. It takes readers through the process of identifying, estimating, analyzing, and evaluating a range of models.

It is quite common to reflect on what startles you. In the most diverse social contexts and cultures, the inescapable physiology of the reflex both shapes the experience of startle and biases the social usage to which the reflex is put. This book describes the ways in which the reflex is experienced, culturally elaborated, and socially used, and offers explanations for both patterned commonalities found across cultures, and for the culture-typical differences which differing cultural systems engender.

Methodological Problems with the Academic Sources of Popular Psychology: Context, Inference, and Measurement examines the relationship between academic and popular psychology from a critical perspective with a focus on issues of methodology. The monograph traces the path from ideas in reputable popular psychology back to the original academic research tradition from which the claims were generated. It also addresses the conceptual and methodological controversies with respect to the original research typically ignored or played down in popular writing. This book covers a range of topics including the question of universal biases in judgment, resurgent notions of "fast" thinking and a cognitive unconscious, the psychology of happiness and other "positive" psychologies, the effects of parenting on child outcomes, and more general issues related to psychological tests and measures. The methodological problems that emerge include problems with generalizing from specific experimental conditions, highly biased sampling, lack of replication of findings, lack of shared referents across subfields, even different authors, as well as confusion around basic statistical and mathematical issues. Methodological Problems with the Academic Sources of Popular Psychology: Context, Inference, and Measurement reviews these issues extensively, offering both a sense of the history and pervasiveness of these issues in the field itself and an opportunity to review and master these difficult ideas.

This book is concerned, in particular, with the research which is undertaken by healthcare practitioners and the evidence which they generate as a result of investigating their practice. In so doing it recognizes that, as well as working in academic life, practitioner researchers are often working as practitioners outside the Academy. It argues that the work of practitioner researchers has a signifi cant contribution to make to healthcare research and so needs to be disseminated further in order to create balanced research communities within the healthcare professions.It takes the view that the work of practitioner researchers has a contribution to make to the work of all people involved in healthcare helping academic researchers to broaden the limited ontological and epistemological perspectives of their research. It can also encourage healthcare practitioners who have not been trained academically to develop their research skills and to realize that they are actually researching into their practice on a day-to-day basis. Finally, it can provide a degree of transparency about therapeutic processes to help clients and patients to see aspects of professional practice and development which are usually hidden from them.The contributors cover a range of themes which address the above issues, such as the limitations of academic life and conventional medical models, ethics, the importance of imaginative writing and the use of story, metaphor, myth and the importance of personal transformation in the professional development of healthcare workers and the relevance of belief and spirituality to healthcare research.

A collection of illustrative adolescent case studies to aid clinicians in problem identification, diagnosis, and treatment planning-the only casebook for the MMPI-A-RF The MMPI-A-RF is linked to current models of psychopathology and personality, and features scales relevant for use with adolescents in a variety of clinical, forensic, and school settings. It mirrors the structure of the MMPI-2-RF, resulting in the most up-to-date, empirically based personality assessment for use with adolescents. Written by the authors of the earlier Case Studies for Interpreting the MMPI-A, this book continues the goal of serving as an authentic and illustrative guide for clinicians in understanding and using the MMPI-A-RF. Since the publication of the original Case Studies, much has changed for clinicians who assess and treat adolescents. The interpretive model described in this book demonstrates how the MMPI-A-RF can assist clinicians in assessing youth today by highlighting sixteen cases that broadly represent adolescents evaluated in clinical and forensic practice. In addition, one of the most common uses for the MMPI-A-RF is in the juvenile court setting-a landscape that has also dramatically changed since the publication of the original MMPI-A. Case Studies for Interpreting the MMPI-A-RF focuses on detailed forensic issues, including legal backgrounds, case law, and assessment methods specific to use of the MMPI-A-RF in juvenile court and related settings. Case Studies for Interpreting the MMPI-A-RF will assist clinicians in understanding MMPI-A-RF interpretation, while also being a valuable teaching tool for courses in assessment.
