Haptics technology is being used more and more in different applications, such as in computer games for increased immersion, in surgical simulators to create a realistic environment for training of surgeons, in surgical robotics due to safety issues and in mobile phones to provide feedback from user action. The existence of these applications highlights a clear need to understand performance metrics for haptic interfaces and their implications on device design, use and application. Performance Metrics for Haptic Interfaces aims at meeting this need by establishing standard practices for the evaluation of haptic interfaces and by identifying significant performance metrics. Towards this end, a combined physical and psychophysical experimental methodology is presented. Firstly, existing physical performance measures and device characterization techniques are investigated and described in an illustrative way. Secondly, a wide range of human psychophysical experiments are reviewed and the appropriate ones are applied to haptic interactions. The psychophysical experiments are unified as a systematic and complete evaluation method for haptic interfaces. Finally, synthesis of both evaluation methods is discussed. The metrics provided in this state-of-the-art volume will guide readers in evaluating the performance of any haptic interface. The generic methodology will enable researchers to experimentally assess the suitability of a haptic interface for a specific purpose, to characterize and compare devices quantitatively and to identify possible improvement strategies in the design of a system.

Mental illness is many things at once: It is a natural phenomenon that is also shaped by society and culture. It is biological but also behavioral and social. Mental illness is a problem of both the brain and the mind, and this ambiguity presents a challenge for those who seek to accurately classify psychiatric disorders. The leading resource we have for doing so is the American Psychiatric Association'sDiagnostic and Statistical Manual, but no edition of the manual has provided a decisive solution, and all have created controversy. InThe Diagnostic System, the sociologist Jason Schnittker looks at the multiple actors involved in crafting theDSMand the many interests that the manual hopes to serve. Is the DSM the best tool for defining mental illness? Can we insure against a misleading approach? Schnittker shows that the classification of psychiatric disorders is best understood within the context of a system that involves diverse parties with differing interests. The public wants a better understanding of personal suffering. Mental-health professionals seek reliable and treatable diagnostic categories. Scientists want definitions that correspond as closely as possible to nature. And all parties seek definitive insight into what they regard as the right target. Yet even the best classification system cannot satisfy all of these interests simultaneously. Progress toward an ideal is difficult, and revisions to diagnostic criteria often serve the interests of one group at the expense of another. Schnittker urges us to become comfortable with the socially constructed nature of categorization and accept that a perfect taxonomy of mental-health disorders will remain elusive. Decision making based on evolving though fluid understandings is not a weakness but an adaptive strength of the mental-health profession, even if it is not a solid foundation for scientific discovery or a reassuring framework for patients.

* It is a straightforward, conversational introduction to statistics that delivers exactly what its title promises. * Each chapter begins with a brief overview of a statistic that describes what the statistic does and when to use it, followed by a detailed step-by-step explanation of how the statistic works and exactly what information it provides. * Chapters also include an example of the statistic (or statistics) in use in real-world research, "Worked Examples," "Writing It Up" sections that demonstrate how to write about each statistic, "Wrapping Up and Looking Forward" sections, and practice work problems. * A new chapter on person-centered analyses, including cluster analysis and latent class analysis (LCA) has been added (Chapter 16). * Person-centered analysis is an important alternative to the more commonly used variable-centered analyses (e.g., t tests, ANOVA, regression) and is gaining popularity in social-science research. * The chapter on non-parametric statistics (Chapter 14) was enhanced significantly with in-depth descriptions of Mann-Whitney U, Kruskall-Wallace, and Wilcoxon Signed-Rank analyses. * These non-parametric statistics are important alternatives to statistics that rely on normally distributed data. * This new edition also includes more information about the assumptions of various statistics, including a detailed explanation of the assumptions and consequences of violating the assumptions of regression (Chapter 13). * There is more information provided about the importance of the normal distribution in statistics (Chapters 4 and 7). * Each of the last nine chapters includes an example from the real world of research that employs the statistic, or statistics, covered in the chapter. * Altogether, these improvements provide important foundational information about how inferential statistics work and additional statistical tools that are commonly used by researchers in the social sciences. * The text works as a standalone or as a supplement and covers a range of statistical concepts from descriptive statistics to factor analysis and person-centered analyses.

The Children's Court is one of society's most important social institutions. At the same time, it is steeped in controversy. This is in large measure due to the persistence and complexity of the problems with which it deals, namely, juvenile crime and child abuse and neglect. Despite the importance of the Children's Court as a means of holding young people accountable for their anti-social behaviour and parents for the care of their children, it has not been the subject of close study. Certainly it has not been previously studied nationally. This book, an edited collection, is based on the findings of study that spanned the six States and two Territories of Australia. The study sought to examine the current challenges faced by the Children's Court and to identify desirable and feasible directions for reform in each State and Territory. A further unique feature of this study is that it canvassed the views of judges and magistrates who preside over this court.

Can the phenomena of the human mind be separated from the practices of spiritual formation-of growing to have the mind of Christ? Research into the nature of moral and spiritual change has revived in recent years in the worlds of psychology on one hand and theology and philosophy on the other. But psychology and spiritual formation draw upon distinct bodies of research and theory grounded in different methodologies, resulting in conversation that has suffered from a lack of interdisciplinary cross-pollination. Rooted in a year-long discussion held by Biola University's Center for Christian Thought (CCT), this volume bridges the gaps caused by professional specialization among psychology, theology, and philosophy. Each essay was forged out of an integrative discussion among theologians, psychologists, philosophers, New Testament scholars, educators, and pastors around the CCT seminar table. Topics that emerged included relational and developmental spirituality, moral virtue and judgment, and suffering and trauma. Psychology and Spiritual Formation in Dialogue speaks across disciplinary divides, fostering fruitful conversation for fresh insights into the nature and dynamics of personal spiritual change.

Porter, professor of theology, spiritual formation, and philosophy, Talbot School of Theology and Rosemead School of Psychology, Biola University Gregg Ten Elshof, professor of philosophy, Biola University Christian Association for Psychological Studies (CAPS) Books explore how Christianity relates to mental health and behavioral sciences including psychology, counseling, social work, and marriage and family therapy in order to equip Christian clinicians to support the well-being of their clients.

Projective Techniques and Sort-Based Research Methods offers a brief introductory guide to the use of these exciting, innovative and often artistic approaches, to students and researchers who have no prior knowledge of these. This book brings together a wide range of examples of projective and mapping techniques that offer the ideal methodology for researchers wishing to collect less controlled and filtered material, that tap the deeper levels of the conscious and sub-conscious to reveal a more profound, richer and hidden level of response. It presents the techniques in a way that will enable the reader to appreciate their nature and to choose an appropriate method for their own research. Information is also provided that allows readers to design and implement their own projective or sort-based approaches. Each of the approaches the authors present are concisely described, and their usages explained, along with references and examples of the applied usage of the technique. The book is valuable reading for researchers from a wide range of academic disciplines from within the social sciences, humanities, business studies, marketing, etc. The book is an introductory guide, but it will be appropriate for use with undergraduate, post-graduate and research students. It will also be of great use to professionals working in the areas of consumer behaviour, marketing and communications.

This volume provides a fast and efficient way for undergraduate and graduate students to gain a solid understanding of the social psychology literature. Each chapter reviews a major subsection of research in the field, written by a leading social psychology researcher in that area. Coverage includes all the major empirical, theoretical and methodological developments in its subfield of social psychology. Beginning social psychologists, as well as those who may have emerged from their formal training with a less-than-solid grounding in the research literature, will find this volume invaluable. It is the book all social psychologists wished they had access to when they were getting grounded in the research literature!

Over the last 20 years there have been a large number of technical advances and changes in the field of educational and psychological testing. According to Anne Anastasi, The decade of the 1980's has been a period of unusual advances in, psychological testing. Technological progress, theoretical sophistication, and increasing pro fessional responsibility are all evident in the fast-moving events in this field (A. Anastasi, Psychological Testing, Sixth Edition. New York: Macmillan, 1988). On the psychometric front, advances in topics such as item response theory, criterion-referenced measurement, generalizability theory, . analy sis of covariance structures, and validity generalization are reshaping the ways that ability and achievement tests are constructed and evaluated, and that test scores are interpreted. But \Jsychometric advances, as substantial and important as they have been, are only a fraction of the major changes in the field of testing. Today, for example, the computer is radically chang ing the ways in which tests are constructed, administered, and scored. Computers are being used to administer tests "adaptively." That is, the sequence of questions an examinee is administered depends upon his or her performance on earlier administered items in the test. Tests are "adapted" to the ability levels of the examinees who are being assessed. One result is shorter tests with little or no loss in measurement precision. Computers are also being used to store or bank test items. Later, items of interest can be selected, and the computer is used to print copies of the test."

*Major revision of a work that gives researchers the tools to select the right theory for their evaluation task. *Clearly lays out the goals of each theory, how it translates into practice, and the conditions under which it is best applicable. *Third edition has an increased focus on diversity/equity and is organized around theories rather than individual theorists. *Top editors and contributors are highly regarded, experienced evaluators.

This unique text covers the core research methods and the philosophical assumptions that underlie various strategies, designs, and methodologies used when researching cultural issues. It teaches readers why and for what purpose one conducts research on cultural issues so as to give them a better sense of the thinking that should happen before they go out and collect data. More than a "methods text", it is about all the steps that go into doing cross-cultural research. It discusses how to select the most appropriate methods for data analysis and which approach to use, and details quantitative, qualitative, and mixed methods for experimental lab studies and ethnographic field work.

What does morality have to do with psychology in a value-neutral, postmodern world? According to a provocative new book, everything. Taking exception with current ideas in the mainstream (including cultural, evolutionary, and neuropsychology) as straying from the discipline's ethical foundations, Psychology as a Moral Science argues that psychological phenomena are inherently moral, and that psychology, as prescriptive and interventive practice, reflects specific moral principles. The book cites normative moral standards, as far back as Aristotle, that give human thoughts, feelings, and actions meaning, and posits psychology as one of the critical methods of organizing normative values in society; at the same time it carefully notes the discipline's history of being sidetracked by overemphasis on theoretical constructs and physical causes-what the author terms "the psychologizing of morality." This synthesis of ideas brings an essential unity to what can sometimes appear as a fragmented area of inquiry at odds with itself. The book's "interpretive-pragmatic approach": * Revisits core psychological concepts as supporting normative value systems. * Traces how psychology has shaped society's view of morality. * Confronts the "naturalistic fallacy" in contemporary psychology. * Explains why moral science need not be separated from social science. * Addresses challenges and critiques to the author's work from both formalist and relativist theories of morality. With its bold call to reason, Psychology as a Moral Science contains enough controversial ideas to spark great interest among researchers and scholars in psychology and the philosophy of science.

One of the major domestic policy issues of our time is whether our nation can provide a more effective educational experience for our children. Economists have stressed that the quality of our educational system eventually defines the ability of our workforce, which in turn affects our competitive position in the world market. This issue has earned increasing attention in light of recent reports that students in many nations perform at higher levels of educational competence than children in America's schools. Inspiring Greatness in Education describes the 21st Century Schools program (21C), a whole-school reform model developed by Edward Zigler over 20 years ago and since then has been in a constant state of testing, implementation, and scaling up. The goal of 21C is to promote optimal child development, which should become manifest in sound educational performance. In practice, 21C provides preschool education as well as good-quality child care before and during the school years, in combination with a number of other family supports. This book will provide an in-depth case study examination of the experience of the Independence School District in Independence, Missouri. The Independence School District embraced School of the 21st Century concepts in 1988, becoming the first urban school district in the nation to do so. This book reveals and documents Independence School District's success as a national model for 21C programming, as well as the experiences, testimonials and opinions of parents, students, teachers, administrators and community officials. By focusing on the impetus and history of the 21C concept, its organic evolution and its applications at the Independence School District, this book is designed to inform, educate, and inspire all who read it and to serve as a model for other school districts that want to achieve similar successes.

Increasing nonresponse rates in surveys are a matter of concern internationally, as low response rates put the quality of survey data into question. The risk of biased data is high if nonrespondents differ significantly from respondents. In arguing that sample persons' personality traits are decisive in survey participation decisions, Denise Sassenroth investigates the mechanisms causing increasing nonresponse rates. Based on a modification of the Social Isolation Hypothesis, she analyses the impact of sample persons' personality on participation decisions with data from the German General Social Survey and the LISS Panel from the Netherlands.

Psychology: A Behavioral Overview is an introductory text with an orienting per spective that is frankly behavioral rather than eclectic. This focus is made quite clear in the first chapter of the book, but in the remainder it also becomes clear that such a focus permits coverage of most of the topics found in the more common introductory text. Actually, the next five chapters (dealing with psy chology as a scienc~, methodology, evolution, physiology, and learning) are in many ways comparable to the treatments provided in more eclectic introductory texts. The behavioral focus and the departure from traditional approaches be come most significant in the last six chapters which deal with traditional psycho logical topics (e. g. , language, child development, and personality)-but deal with them systematically in terms of the concepts and principles introduced in the chapters on evolution and physiology, and especially in the chapter on learning. Using the concepts provided early in the text to interpret complex aspects of human behavior provides valuable justification for those concepts, as well as an opportunity for improved understanding of them. Although students will not make extensive contact with the variety of the oretical approaches found in the typical text, they will become especially compe tent in the use of behavioral concepts and principles to interpret and understand many of the topics of traditional importance in psychology.

Leadership, Work, and the Dark Side of Personality uses an interpersonal psychological perspective to unite general theories of both personality and leadership. By focusing in on the interpersonal, the book characterizes social behaviors by their agency (how dominant they are) and by their communion (how relational and nurturing they are). It argues that these interpersonal dimensions align closely with the traditional structure of leader behaviors-both task-related and relationship oriented behaviors-and uses those frameworks to orient trait theory for both normal-range personality traits and subclinical (dark side) traits. After overviewing the history of leadership theory, reviewing normal range personality traits (Extraversion, Neuroticism, Conscientiousness, Agreeableness and Openness) and subclinical traits, such as the Dark Triad (Narcissism, Machiavellianism and Psychopathy), the book moves on to thoroughly bring the perspective of interpersonal psychology to bear on questions of personality and leadership, and ends by narrowing in on how the dark side of personality affects the leadership process-for better and for worse.

The field of close relationships is one of the most fertile areas of work in the social and behavioural sciences. Central to theoretical developments in the study of close relationships is a focus on people's interpretive activities and communication behavior. Theories of attribution and of communication styles are prominent in explanations of why and how people begin close relationships, maintain and enhance closeness, and sometimes terminate close relationships. Originally published in 2001, Attribution, Communication Behavior, and Close Relationships brings together scholars from a variety of disciplines whose work focuses on the interplay of attribution processes and communication behavior in close relationships. The book shows ways in which diverse scholarly perspectives can blend to provide insight into areas of common interest. In this case, it is the ways that people in relationships think about communication, make attributions through communication, and communicate about the attributions they make.

The Stirling Psychology of Language Conference was held in the University of Stirling, 21-26 June 1976. 250 people attended the conference and 70 papers were presented. The two volumes of Pro ceedings present a selection of papers from the conference reflect ing as far as possible the range of topics that were discussed. Volume 1 is concerned exclusively with language acquisition. In recent years the 'centre of gravity' of acquisition research has shifted from syntactic and phonological description to the amor phous domains of semantics and pragmatics. This shift is reflected in the two large sections (II and III) devoted to these aspects of language development. In addition the volume contains three smaller sections dealing with general problems of acquisition theory, syntax and the development of comprehension, and applied developmental psycholinguistics. Volume 2 contains a substantial section of papers which stress the formal aspects of psycholinguistics: these include papers in which artificial intelligence figures prominently, papers which apply re cent developments in syntax and semantics to psycholinguistic prob lems, and papers that are broadly critical of the use psychologists have made of linguistic theories. Volume 2 also contains a section dealing with the experimental study of sentence comprehension and production, and there is a final section concerned with phonology and its development."

THE FORMATIVE TENDENCY I have often pointed out that in my work with individuals in therapy, and in my experience in encounter groups, I have been led to the con viction that human nature is essentially constructive. When, in a ther apeutic climate (which can be objectively defined) a person becomes sharply aware of more of his or her internal experiencing and of the stimuli and demands from the external world, thus acquiring a full range of options, the person tends to move in the direction of becoming a socially constructive organism. But many are critical of this point of view. Why should such a positive direction be observed only in humans? Isn't this just pure op- . . ? timi sm. So quite hesitantly, because I have to draw on the work and thinking of others rather than on my own experience, I should like to try to set this directional tendency in a much broader context. I shall draw on my general reading in the field of science, but I should like to mention a special indebtedness to the work of Lancelot Whyte in The Universe of Experience (Harper and Row, 1974), the last book he wrote before his death. Though the book has flaws, in my judgment this historian has some thought-provoking themes to advance. I have learned from many others as well."

With its emphasis on practical and conceptual aspects, rather than mathematics or formulas, this accessible book has established itself as the go-to resource on confirmatory factor analysis (CFA). Detailed, worked-through examples drawn from psychology, management, and sociology studies illustrate the procedures, pitfalls, and extensions of CFA methodology. The text shows how to formulate, program, and interpret CFA models using popular latent variable software packages (LISREL, Mplus, EQS, SAS/CALIS); understand the similarities and differences between CFA and exploratory factor analysis (EFA); and report results from a CFA study. It is filled with useful advice and tables that outline the procedures. The companion website (www.guilford.com/brown3-materials) offers data and program syntax files for most of the research examples, as well as links to CFA-related resources. New to This Edition *Updated throughout to incorporate important developments in latent variable modeling. *Chapter on Bayesian CFA and multilevel measurement models. *Addresses new topics (with examples): exploratory structural equation modeling, bifactor analysis, measurement invariance evaluation with categorical indicators, and a new method for scaling latent variables. *Utilizes the latest versions of major latent variable software packages.

The present volume is a continuation of Volume 8 in the Annals series. Together Volumes 8 and 9 are intended to show the contribu- tion of history to theory in psychology.

This book provides a detailed examination of argumentative interactions in families with young children during mealtimes. It explores both the restrictions and the opportunities family mealtimes present and the types of issues addressed through argumentative discussions. Antonio Bova puts forward an in depth analysis of how both parents and children contribute to the inception and development of an argumentative discussion, and the categories of argument adopted most often by the two groups. Drawing upon a wealth of qualitative data from the recorded mealtime conversations of Italian and Swiss-Italian middle-class families, the author examines the crucial importance of argumentative interactions between parents and children during mealtimes. This book builds on recent advances in the study of the psychology of social interaction and sheds new light on the importance of argumentation at all stages of life.

Interest in the field of neurodevelopmental disorders has grown exponentially in recent years across a range of disciplines, including psychology, psychiatry, education and neuroscience. The research itself has become more sophisticated, using multidisciplinary methods to probe interdisciplinary questions. Neurodevelopmental Disorders: Research Challenges and Solutions provides a thorough overview of the key issues involved in researching neurodevelopmental disorders. The volume includes 14 chapters, arranged over three sections. Chapters in the first section address general research challenges for the study of neurodevelopmental disorders. The second section draws upon specific disorders (such as Williams syndrome, Autism Spectrum Disorders, Down Syndrome, Fragile X Syndrome, ADHD, and Language Disorders) to consider the syndrome-specific issues or challenges that may be crucial to advancing our understanding of aspects of cognition and behavior associated with them. The final section considers how research evidence may be translated into practice to begin making an impact upon the lives of individuals who have neurodevelopmental disorders and their families. Each chapter in the book also includes 'practical tips' for either conducting research with individuals who have neurodevelopmental disorders or considering wider practical issues. The book will be indispensable reading for advanced students, researchers, and practitioners in the fields of developmental psychology, developmental psychopathology, special needs education, neuropsychology, and neurodevelopmental disorders.

This is the first of a two-volume work in the Annals series devoted to developmental psychology. The project was originally conceived in 1985 when Paul van Geert, who had just completed his Theory building in developmental psychology (North Holland, 1986), agreed to col laborate on anAnnals volume examining foundational issues pertaining to the concept of development. The project attracted considerable interest and, in view of the length of the resulting manuscript, a decision was made to publish it in two volumes. Fortunately, the contributors provided coherent perspectives on two relatively distinct developmen tal themes which served to facilitate our task of dividing their contribu tions into two volumes. The first volume deals with the foundations of developmental theory and methodology; the second volume -to appear as Volume 8 of the Annals -with theoretical issues in developmental psychology. In this first volume, the contributions by Willis Overton and Joachim Wohlwill were completed in 1988, those by Roger Dixon, Richard Lerner, and David Hultsch, and Paul van Geert in 1989. Commentaries followed quickly and replies to commentaries were completed in 1990. Paul van Geert provides a general framework within which the founda tional issues of development are discussed. He is especially concerned with the nature of transition models and the structure of time in developmental theory. The relationship between methods and framework, or theory, is the topic of Joachim Wohlwill's contribution."

Missing data affect nearly every discipline by complicating the statistical analysis of collected data. But since the 1990s, there have been important developments in the statistical methodology for handling missing data. Written by renowned statisticians in this area, Handbook of Missing Data Methodology presents many methodological advances and the latest applications of missing data methods in empirical research. Divided into six parts, the handbook begins by establishing notation and terminology. It reviews the general taxonomy of missing data mechanisms and their implications for analysis and offers a historical perspective on early methods for handling missing data. The following three parts cover various inference paradigms when data are missing, including likelihood and Bayesian methods; semi-parametric methods, with particular emphasis on inverse probability weighting; and multiple imputation methods. The next part of the book focuses on a range of approaches that assess the sensitivity of inferences to alternative, routinely non-verifiable assumptions about the missing data process. The final part discusses special topics, such as missing data in clinical trials and sample surveys as well as approaches to model diagnostics in the missing data setting. In each part, an introduction provides useful background material and an overview to set the stage for subsequent chapters. Covering both established and emerging methodologies for missing data, this book sets the scene for future research. It provides the framework for readers to delve into research and practical applications of missing data methods.
