This textbook is an approachable introduction to statistical analysis using matrix algebra. Prior knowledge of matrix algebra is not necessary. Advanced topics are easy to follow through analyses that were performed on an open-source spreadsheet using a few built-in functions. These topics include ordinary linear regression, as well as maximum likelihood estimation, matrix decompositions, nonparametric smoothers and penalized cubic splines. Each data set (1) contains a limited number of observations to encourage readers to do the calculations themselves, and (2) tells a coherent story based on statistical significance and confidence intervals. In this way, students will learn how the numbers were generated and how they can be used to make cogent arguments about everyday matters. This textbook is designed for use in upper level undergraduate courses or first year graduate courses. The first chapter introduces students to linear equations, then covers matrix algebra, focusing on three essential operations: sum of squares, the determinant, and the inverse. These operations are explained in everyday language, and their calculations are demonstrated using concrete examples. The remaining chapters build on these operations, progressing from simple linear regression to mediational models with bootstrapped standard errors.

In these uncertain times, how much can you trust health news? Is the research behind breaking headlines reliable? This book is an indispensable resource for students and general readers, helping them evaluate and think critically about health information. "People Who Drink Coffee Live Longer." "Students Learn Better When Listening to Classical Music." "Scientists Discover the Gene That Causes Obesity." We are constantly bombarded with reports of "groundbreaking" health findings that use attention-grabbing headlines and seem to be backed by credible science. Yet many of these studies and the news articles that discuss them fall prey to a variety of problems that can produce misleading and inaccurate results. Some of these may be easy to notice-like a research study on the benefits of red meat funded by the beef industry, or a study with a sample size of only 10 people-but others are much harder to spot. Skewed Studies: Exploring the Limits and Flaws of Health and Psychology Research examines the most pervasive problems plaguing health research and reporting today, using clear, accessible language and employing real-world examples to illustrate key concepts. Beyond simply outlining issues, it provides readers with the knowledge and skills to evaluate research studies and news reports for themselves, improving their health literacy and critical thinking skills. Brings together and thoroughly explores the many ways in which health research and reporting can be flawed and problematic Improves readers' critical thinking skills and gives them practical tools to better evaluate the health information they come across Explains scientific and statistical concepts in clear, easy-to-understand language Includes a curated and annotated directory of resources for readers seeking additional information

From its foundation in the 1950s by George Kelly, Personal Construct Psychology continued to grow, both as a movement among psychologists and then in industry, education, government and commerce. Originally published in 1985 this title offers a compendium of elaborations and new conversational uses for Kelly's repertory grid technique. The authors have dramatically transformed the grid from a static measuring instrument to a dynamic tool for a personal exploration of the learning process itself. This grid-based Reflective Learning Technology enables individuals, pairs, groups and organisations to develop their learning in environments of work, family, education and society. As the originators and best-known practitioners of interactive grids, the authors give the reader an A-Z of these techniques. Case studies include management training, quality control, staff appraisal, job selection, team building, manufacturing, marketing and production as well as learning at a distance, learning to learn in schools, youth training, reading to learn and other learning skills, staff development, social work, counselling and therapy. Their development of a theory of learning conversation and conversational grid software opens up an imaginative, exciting and more humane approach to the use of microcomputers in all forms of education, while at the same time demonstrating the essentially autonomous nature of human learning. Available again after many years out of print, this book is of even greater value today than when first published.

If you find yourself called on to judge people on a regular basis, you need all the tools at your disposal to do your job right. Handwriting psychology offers one practical method for helping you learn what you need to learn about your subject quickly.

Whether you are a teacher, psychologist or manager, you can benefit from the guidance of Dr. Helmut Ploog, a handwriting expert. Learn what the size and width of handwriting can reveal about a person, as well as what more muted features-such as slant, spacing, and direction of lines-can make clear.

Written in plain English, this guidebook presents pithy explanations of handwriting movements, which may be angular or round, long or short, heavy or light, high or deep below the base line. It also offers analyses of the handwriting of many well-known people, including Charles Darwin, Anne Frank, Paul Getty, Allen Ginsberg, Ernest Hemingway, Frida Kahlo, Somerset Maugham, Pablo Picasso, Pope Benedict, Vladimir Putin, Maurice Ravel, Carl Rogers, and Susan Sontag.

"Handwriting Psychology" should never be used by itself to judge someone, but it can serve as an essential tool to make and confirm observations that could change your life, your career, and your approach to life.

The past forty years have revealed a myriad of theoretical advances to Freud s original conceptions of the personality. It has also witnessed the continued use of projective methods as a vital means of understanding the what and the how of mental health and psychopathology. Understanding Personality Through Projective Testing provides the reader with a comprehensive framework for linking these revitalized key domains of personality functioning to the quality of responses to projective testing in both children and adults. Six core aspects of personality: two facets of object relations (moving towards and away from self and others); the quality of defense mechanisms; the nature of affect maturity; the integrity of autonomous ego functioning and the capacity for playfulness are defined, articulated, and linked to one another in a reciprocal manner. Four commonly used projective testing methods: the Rorschach Inkblot Method (RIM); the Thematic Apperception Test (TAT), the Sentence Completion Test (SCT), and the Animal Preference Test (APT) are then described in detail. Each of these projective methods is in turn presented as dynamically-based tools to indicate the relative performance of the patient across the six core personality domains. Clinical case examples provide both the beginning and more seasoned clinician with a comprehensive psychodynamic paradigm with which to view each of the testing methods, as well as enhanced methods with which to use each of the tests more subtly and hence with greater clinical acumen. A comprehensive battery of projective testing is then assessed through the protocol of a single adult patient, allowing the reader to integrate the value of each of the individual projective methods into a comprehensive assessment of the whole person. Readers will find the book a vital complement to both standard reference works on projective methods as well as books that describe personality along developmental and psychodynamic lines."

The chapters in this new volume describe original research concerned with both theory and practice in measurement. The material originated in presentations made at a conference that brings together practicing professionals and theoreticians in diverse areas of measurement and related fields. The first group of papers embody the most important aspect of objective measurement - its application to diverse contexts and purposes. The examples included concentrate on two types of situations: performance assessment and criterion-referenced testing. The specific contexts range from writing assessment, to assessment of the professional development of teachers, to high school physics. The second group of papers are focused on an area of great importance in assessment today: the modeling of raters and judges in an assessment context. The volume concludes with papers that explore the domain of theory in measurement, characterized by an innovative approach to model-building. Even though they are categorized as theory papers, most are based on the complicated and interesting problems that arise in quite specific contexts. As such, they represent some of the most original and exciting developments in the field of measurement today ranging from multidimensional measurement to graph theory and clustering techniques. This volume presents original research concerned with the practice of measurement, and the theory of measurement. The words in the title, objective measurement indicate that the chapters are all related to a particular approach to the philosophy and practice of measurement. By objective measurement, we mean that, in a situation where a certain class of stimuli (for example, items) are used to measure certain individuals. The chapters in this book originated in presentations made at the International Objective Measurement Workshop (IOMW) devoted to exploring the interface between theory and practice in measurement. Based on the complicated and interesting problems that arise in quite specific contexts, they represent some of the most original and exciting developments in the field of measurement today.

Originally published in 1953 this book provided the first comprehensive account of methods of personality assessment by a British author. It starts with a short survey of personality theory, pointing out the difficulties in any method of testing or assessment. Next it describes the weaknesses of the common interview method. (Throughout the emphasis is on methods which are usable in educational or vocational guidance and selection, not on methods which are mainly of scientific interest.) Thereafter it takes up each main type of technique - tests based on physique or psychological measures, on expressive movement such as gestures and handwriting, tests of behaviour (including War Office Selection Board 'house party' methods), ratings and rating scales, questionnaires, and so-called projective techniques. The evidence for or against each test or method is surveyed and numerous references provided for relevant literature. Illustrative excerpts are given of many of the more promising tests, and some pictorial illustrations. British work in this field at the time is covered completely, and an attempt is made to provide a fair summary of the main contributions of American and other psychologists of the day.

Originally published in 1964, the aim of this book was to analyse the psychological processes involved in understanding personality, and to consider how the psychologist could help in making more accurate assessments. Professor Vernon discusses in detail the scientific status of psychoanalytic and other 'depth' theories of motivation, the value of different types of psychotherapeutic treatment and counselling, the influence of upbringing on the development of personality, and the effectiveness of projective techniques. He also examines the reasons for the highly variable results obtained with personality tests and questionnaires. As well as providing a balanced review of theories of personality and of various types of test, this work made a fresh contribution to developing improved techniques of assessment.

The crux of the debate between proponents of behavioral psychology and cognitive psychology focuses on the issue of accessibility. Cognitivists believe that mental mechanisms and processes are accessible, and that their inner workings can be inferred from experimental observations of behavior. Behaviorists, on the contrary, believe that mental processes and mechanisms are inaccessible, and that nothing important about them can be inferred from even the most cleverly designed empirical studies. One argument that is repeatedly raised by cognitivists is that even though mental processes are not directly accessible, this should not be a barrier to unravelling the nature of the inner mental processes and mechanisms. Inference works for other sciences, such as physics, so why not psychology? If physics can work so successfully with their kind of inaccessibility to make enormous theoretical progress, then why not psychology? As with most previous psychological debates, there is no "killer argument" that can provide an unambiguous resolution. In its absence, author William Uttal explores the differing properties of physical and psychological time, space, and mathematics before coming to the conclusion that there are major discrepancies between the properties of the respective subject matters that make the analogy of comparable inaccessibilities a false one. This title was first published in 2008.

Psychological Statistics: The Basics walks the reader through the core logic of statistical inference and provides a solid grounding in the techniques necessary to understand modern statistical methods in the psychological and behavioral sciences. This book is designed to be a readable account of the role of statistics in the psychological sciences. Rather than providing a comprehensive reference for statistical methods, Psychological Statistics: The Basics gives the reader an introduction to the core procedures of estimation and model comparison, both of which form the cornerstone of statistical inference in psychology and related fields. Instead of relying on statistical recipes, the book gives the reader the big picture and provides a seamless transition to more advanced methods, including Bayesian model comparison. Psychological Statistics: The Basics not only serves as an excellent primer for beginners but it is also the perfect refresher for graduate students, early career psychologists, or anyone else interested in seeing the big picture of statistical inference. Concise and conversational, its highly readable tone will engage any reader who wants to learn the basics of psychological statistics.

First published in 1950, this revised edition of The Structure of Human Abilities was published in 1961, but remained largely unchanged from the original save for an additional supplement on the developments in factorial work on human abilities from 1950-1959. Much research had been carried out during the years leading up to publication, in England and America, into mental abilities; and modern methods of statistical treatment, especially factor analysis, had been increasingly used. It was felt that the mass of diverse material was apt to confuse the student of psychology of the time, especially as the results of such research were often apparently conflicting. Professor Vernon, one of the leading experts in this branch of psychology, sifted the material and attempted to provide a consistent picture of our mental structure.

The goal of this book is to emphasize the formal statistical features of the practice of equating, linking, and scaling. The book encourages the view and discusses the quality of the equating results from the statistical perspective (new models, robustness, fit, testing hypotheses, statistical monitoring) as opposed to placing the focus on the policy and the implications, which although very important, represent a different side of the equating practice. The book contributes to establishing "equating" as a theoretical field, a view that has not been offered often before. The tradition in the practice of equating has been to present the knowledge and skills needed as a craft, which implies that only with years of experience under the guidance of a knowledgeable practitioner could one acquire the required skills. This book challenges this view by indicating how a good equating framework, a sound understanding of the assumptions that underlie the psychometric models, and the use of statistical tests and statistical process control tools can help the practitioner navigate the difficult decisions in choosing the final equating function. This book provides a valuable reference for several groups: (a) statisticians and psychometricians interested in the theory behind equating methods, in the use of model-based statistical methods for data smoothing, and in the evaluation of the equating results in applied work; (b) practitioners who need to equate tests, including those with these responsibilities in testing companies, state testing agencies, and school districts; and (c) instructors in psychometric, measurement, and psychology programs.

Item response theory has become an essential component in the toolkit of every researcher in the behavioral sciences. It provides a powerful means to study individual responses to a variety of stimuli, and the methodology has been extended and developed to cover many different models of interaction. This volume presents a wide-ranging handbook to item response theory - and its applications to educational and psychological testing. It will serve as both an introduction to the subject and also as a comprehensive reference volume for practitioners and researchers. It is organized into six major sections: the nominal categories model, models for response time or multiple attempts on items, models for multiple abilities or cognitive components, nonparametric models, models for nonmonotone items, and models with special assumptions. Each chapter in the book has been written by an expert of that particular topic, and the chapters have been carefully edited to ensure that a uniform style of notation and presentation is used throughout. As a result, all researchers whose work uses item response theory will find this an indispensable companion to their work and it will be the subject's reference volume for many years to come.

Statistical Power Analysis explains the key concepts in statistical power analysis and illustrates their application in both tests of traditional null hypotheses (that treatments or interventions have no effect in the population) and in tests of the minimum-effect hypotheses (that the population effects of treatments or interventions are so small that they can be safely treated as unimportant). It provides readers with the tools to understand and perform power analyses for virtually all the statistical methods used in the social and behavioral sciences. Brett Myors and Kevin Murphy apply the latest approaches of power analysis to both null hypothesis and minimum-effect testing using the same basic unified model. This book starts with a review of the key concepts that underly statistical power. It goes on to show how to perform and interpret power analyses, and the ways to use them to diagnose and plan research. We discuss the uses of power analysis in correlation and regression, in the analysis of experimental data, and in multilevel studies. This edition includes new material and new power software. The programs used for power analysis in this book have been re-written in R, a language that is widely used and freely available. The authors include R codes for all programs, and we have also provided a web-based app that allows users who are not comfortable with R to perform a wide range of analyses using any computer or device that provides access to the web. Statistical Power Analysis helps readers design studies, diagnose existing studies, and understand why hypothesis tests come out the way they do. The fifth edition includes updates to all chapters to accommodate the most current scholarship, as well as recalculations of all examples. This book is intended for graduate students and faculty in the behavioral and social sciences; researchers in other fields will find the concepts and methods laid out here valuable and applicable to studies in many domains.

The world of Research Methods is always changing and becoming ever more complex. Now completely up to date with the latest innovations, this book engages with recent controversies to give you the best start with your research. In each chapter you will find: * Key concept boxes to help you stay on track and focus on what's most important * Real life examples which make the theory easier to understand * Exercises to check you've understood the chapter * Questions to help you develop your critical thinking.

Against the background of NATO's Istanbul conference of 1971 (Cronbach and Drenth, 1972), the Kingston conference shows that great progress has been made by the community of cross-cultural psychologists. The progress is as much in the psychology of the investigators as in the investigations being reported. In 1971 the investigators were mostly strangers to each other. Behind their reports lay radically different field experiences, disparate research traditions, and mutually contradictory social ideals. Istanbul was not a Tower of Babel, but participants did speak past each other. Now a community exists, thanks to the meetings of NATO and the International Association for Cross-Cultural Psychology, to flourishing journals, and the Triandis et a1. (1980) Handbook. The members tend to know each other, can anticipate how their formu lations will fallon the ears of others, and accept superficially divergent approaches as making up a collective enterprise. Ten years ago there was open conflict between those who con fronted exotic peoples with traditional tests and applied tradi tional interpretations to the responses, and the relativists who insisted that tasks, test taking, and interpretation cannot be "standardized" in the ways that matter. Today's investigators are conscious of the need to revalidate tasks carried into alien settings; they often prefer to redesign the mode of presentation and to attune the subject to test taking. They face the diffi culties squarely and recognize that even the best means of coping are only partially successful."

This book considers some of the most notable aspects of the legal response to the "war on terror" post- 9/11 and the use of technology to support them. It examines the shift from a criminal justice response to the creation of a parallel preventive system running in tandem with it. This system has tended to veer away from the commission of criminal offences or adherence to ordinary criminal justice safeguards. Such a preventive strategy relies on targeting terrorist suspects - those who it is thought may in future commit terrorist acts - and curbing their actions with the aim of preventing terrorist activity before it occurs. The book further considers the role that surveillance plays in the counter-terrorist efforts of state or non-state actors. It also evaluates the counter-productive effects that many of these measures have had. This book was originally published as a special issue of International Review of Law Computers & Technology.

Psychoanalytic infant observation is frequently used in training psychoanalytic psychotherapists and allied professionals, but increasingly its value as a research method is being recognised, particularly in understanding developmental processes in vulnerable individuals and groups. This book explores the scope of this approach and discusses its strengths and limitations from a methodological and philosophical point of view.

Infant Observation and Research uses detailed case studies to demonstrate the research potential of the infant observation method. Divided into three sections this book covers

• infant observation as part of the learning process
• how infant observation can inform understanding and influence practice
• psychoanalytic infant observation and other methodologies.

Throughout the book, Cathy Urwin, Janine Sternberg and their contributors introduce the reader to the nature and value of psychoanalytic infant observation and its range of application. This book will therefore interest a range of mental health practitioners concerned with early development and infants' emotional relationships, as well as academics and researchers in the social sciences and humanities.

Measurement plays a fundamental role both in physical and behavioral sciences, as well as in engineering and technology: it is the link between abstract models and empirical reality and is a privileged method of gathering information from the real world.

Is it possible to develop a single theory of measurement for the various domains of science and technology in which measurement is involved? This book takes the challenge by addressing the following main issues: What is the meaning of measurement? How do we measure? What can be measured?

A theoretical framework that could truly be shared by scientists in different fields, ranging from physics and engineering to psychology is developed. The future in fact will require greater collaboration between science and technology and between different sciences. Measurement, which played a key role in the birth of modern science, can act as an essential interdisciplinary tool and language for this new scenario.

A sound theoretical basis for addressing key problems in measurement is provided. These include perceptual measurement, the evaluation of uncertainty, the evaluation of inter-comparisons, the analysis of risks in decision-making and the characterization of dynamical measurement. Currently, increasing attention is paid to these issues due to their scientific, technical, economic and social impact. The book proposes a unified probabilistic approach to them which may allow more rational and effective solutions to be reached.

Great care was taken to make the text as accessible as possible in several ways. Firstly, by giving preference to as interdisciplinary a terminology as possible; secondly, by carefully defining and discussing all key terms. This ensures that a wide readership, including people from different mathematical backgrounds and different understandings of measurement can all benefit from this work. Concerning mathematics, all the main results are preceded by intuitive discussions and illustrated by simple examples. Moreover, precise proofs are always included in order to enable the more demanding readers to make conscious and creative use of these ideas, and also to develop new ones.

The book demonstrates that measurement, which is commonly understood to be a merely experimental matter, poses theoretical questions which are no less challenging than those arising in other, apparently more theoretical, disciplines.

This volume, the first to specifically address the function of psychologists as practitioners and scientists in medical settings, presents a range of approaches to assessment and diagnostic practice rather than a litany of specific tools, diseases, or diagnostic problems. The comprehensive discussion, augmented by 41 case studies, addresses the psychological assessment of patients and their families using traditional neuropsychological and psychological diagnostic tools in various topic areas and settings. The application of assessment to issues such as ethics and law, professional self-assessment and credentialling, and the communication of diagnostic findings is also discussed.

Hardbound. Over the last three decades there have been marked developments in the field of measurement in education and psychology. Advances in Measurement in Educational Research and Assessment presents the developments that have occurred and puts them into perspective. It discusses the continuing challenge to improve measurement both for research and for the assessment of student performance and learning in schools, and looks at the substantial advances that are likely to continue to occur in the future. The volume specifies procedures that have been developed to cover a wide range of situations in both research and the assessment of student learning. Although emphasis is placed on the use of the Rasch model, it is recognized that there is a range of different strategies that might be employed for successful measurement, that there are many unresolved issues, and that progress is still being made in this field.
