Cluster analysis is a multivariate classification technique that allows for identification of homogenous subgroups within diverse samples based on shared characteristics. In recent years, cluster analysis has been increasingly applied to psychological and neuropsychological variables to address a number of empirical questions. This book provides an overview of cluster analysis, including statistical and methodological considerations in its application to neurobehavioral variables. First, an introduction to cluster analysis is presented that emphasizes issues of relevance to neuropsychological research, including controversies surrounding it use. Cluster analysis is then applied to clinical disorders that do not have an associated prototypical neuropsychological profile, including traumatic brain injury, schizophrenia, and health problems associated with homelessness. In a second application, cluster analysis is used to investigate the course of normal memory development. Finally, cluster analysis is applied to classification of brain injury severity in children and adolescents who sustained traumatic brain injury.

This book introduces the latest meta-analytical methods and discusses their applications in the field of psychiatry. A comprehensive list of methods used in meta-analysis has been described in simple language and demonstrated with real-time examples. This informative volume explains the importance of meta-analysis and describes how it differs from narrative and systematic reviews. It also relates the historical development of meta-analysis and explains methods used for locating and selecting the required studies in a given domain. Suitable software is examined in detail as well.

This volume is the most comprehensive reference book on community sentiment available. The classic book about community sentiment is Norm Finkel's "Commonsense Justice: Jurors' Notions of the Law" (1995). A similarly influential book called "Justice, Liability, and Blame" was published at the same time, examining lay sentiment about a variety of criminal issues and suggesting ways in which the substantive criminal law could be reformed in light of such lay responses (Robinson & Darley, 1995). Although these books were influential and important for their time (and since), this Handbook expands significantly on them, both by updating research since that time and broadens the scope of topic areas to ones that are not limited to trial and criminal justice issues. Each chapter is original/unpublished and focuses on an area related to children/families, many of which are "hot topic" areas in the news and courts today. For instance, the U.S. Supreme Court decided a case in June 2012 about the constitutionality of "life without parole" for juvenile offenders-a topic discussed in the Fass and Miora chapter. Thus, it is of interest to those interested in family law topics as well.

Exploit the full potential of the WPPSI-IV with analysis from multiple perspectives Essentials of WPPSI-IV Assessment is a comprehensive guide to administering, scoring, and interpreting the latest edition of the Wechsler Preschool and Primary Scale of Intelligence, which represents a major revision of the prior edition. Step-by-step guidelines walk readers through the process, and new Behind the Scenes boxes provide unprecedented insight into the new subtests and the test development process. The book highlights common errors and complex aspects so readers can avoid them, and includes illustrative case studies based on data collected during the scale's standardization to assist in proper administration and interpretation. The companion CD provides software that automates score interpretation, and supplies users with tools to enhance WPPSI-IV administration and report writing. Used to evaluate for learning or intellectual disabilities, developmental or language delays, or gifted and talented classification, the Wechsler Preschool and Primary Scale of Intelligence is the most widely used assessment of intelligence for young children. Essentials of WPPSI-IV Assessment applies an interpretive approach that allows flexibility in response to the real constraints and challenges inherent in working with children, describing performance in both normative and interpersonal contexts to facilitate interpretive case formulations from multiple theoretical and clinical perspectives. Topics include: * WPPSI-IV administration and clinical applications * Scoring, score analysis, and interpretation * Strengths and weaknesses of the WPPSI-IV * Differences across demographic groups The book and accompanying CD also provide alternatives for situations in which published comparison scores may not be available or applicable to a particular child, and supplies composite scores aimed at facilitating WPPSI-IV interpretation from a variety of theoretical approaches. Those who employ the WPPSI-IV must have a thorough grasp of the full potential of the tool, and Essentials of WPPSI-IV Assessment contains the insight and information that allow for deeper understanding.

Understanding how our brains and bodies actually work is a powerful tool in mitigating the anxiety generated by unpleasant physical and emotional symptoms that we all may experience from time to time. Here, Robert Scaer unravels the complexities of the brain-body connection, equipping all those who are in distress with a plausible explanation for how they feel. Making the science accessible, he outlines the core neurobiological concepts underlying the brain-body interface and explains why physical and emotional symptoms of stress and trauma occur. He explains why "feelings" represent physical sensations that inform us about the nature of our brain-body conflicts. He also offers practical, easy-to-implement strategies for strengthening motor skills, learning to listen to our gut to gauge our feelings, attuning to the present, and restoring personal boundaries to relieve symptoms and navigate a path to recovery.

This book combines an overview of validity theory, trends in validation practices and a review of standards and guidelines in several international jurisdictions with research synthesis of the validity evidence in different research areas. An overview of theory is both useful and timely, in view of the increased use of tests and measures for decision-making, ranking and policy purposes in large-scale testing, assessment and social indicators and quality of life research. Research synthesis is needed to help us assemble, critically appraise and integrate the overwhelming volume of research on validity in different contexts. Rather than examining whether any given measure is "valid", the focus is on a critical appraisal of the kinds of validity evidence reported in the published research literature. The five sources of validity evidence discussed are: content-related, response processes, internal structure, associations with other variables and consequences. The 15 syntheses included here, represent a broad sampling of psychosocial, health, medical and educational research settings, giving us an extensive evidential basis to build upon earlier studies. The book concludes with a meta-synthesis of the 15 syntheses and a discussion of the current thinking of validation practices by leading experts in the field.

The 78th Annual Meeting of the Psychometric Society (IMPS) builds on the Psychometric Society's mission to share quantitative methods relevant to psychology. The chapters of this volume present cutting-edge work in the field. Topics include studies of item response theory, computerized adaptive testing, cognitive diagnostic modeling, and psychological scaling. Additional psychometric topics relate to structural equation modeling, factor analysis, causal modeling, mediation, missing data methods, and longitudinal data analysis, among others. The papers in this volume will be especially useful for researchers in the social sciences who use quantitative methods. Prior knowledge of statistical methods is recommended. The 78th annual meeting took place in Arnhem, The Netherlands between July 22nd and 26th, 2013. The previous volume to showcase work from the Psychometric Society's Meeting is New Developments in Quantitative Psychology: Presentations from the 77th Annual Psychometric Society Meeting (Springer, 2014).

While empirical, scientific research has much to offer to the practice-oriented therapist in training, it is often difficult to effectively engage the trainee, beginning practitioner, or graduate student in the subject of research. This fully revised and expanded edition of Research for the Psychotherapist is an engaging, accessible guide that bridges the gap between gathering, analyzing, presenting, and discussing research and incorporating that research into practice. The authors present concise chapters that distill research findings and clearly apply them to practical issues, while also helping readers progress as consumers of relevant research.

This book provides an introduction to test equating, scaling and linking, including those concepts and practical issues that are critical for developers and all other testing professionals. In addition to statistical procedures, successful equating, scaling and linking involves many aspects of testing, including procedures to develop tests, to administer and score tests and to interpret scores earned on tests. Test equating methods are used with many standardized tests in education and psychology to ensure that scores from multiple test forms can be used interchangeably. Test scaling is the process of developing score scales that are used when scores on standardized tests are reported. In test linking, scores from two or more tests are related to one another. Linking has received much recent attention, due largely to investigations of linking similarly named tests from different test publishers or tests constructed for different purposes. In recent years, researchers from the education, psychology and statistics communities have contributed to the rapidly growing statistical and psychometric methodologies used in test equating, scaling and linking. In addition to the literature covered in previous editions, this new edition presents coverage of significant recent research.

In order to assist researchers, advanced graduate students and testing professionals, examples are used frequently and conceptual issues are stressed. New material includes model determination in log-linear smoothing, in-depth presentation of chained linear and equipercentile equating, equating criteria, test scoring and a new section on scores for mixed-format tests. In the third edition, each chapter contains a reference list, rather than having a single reference list at the end of the volume

The themes of the third edition include:

* the purposes of equating, scaling and linking and their practical context

* data collection designs

* statistical methodology

* designing reasonable and useful equating, scaling, and linking studies

* importance of test development and quality control processes to equating

* equating error, and the underlying statistical assumptions for equating

In a multimethod laboratory study Alessia Ruf compared multimodal learning in system-paced and self-paced environments over time. The results show that overall participants achieved the highest learning success in short- and long-term when they learned with visual texts and controlled the learning time by themselves. These results reveal a general impression of the modality effect, show possibilities to improve e-learning systems and give recommendations for further research.

BASIC STATISTICS FOR THE BEHAVIORAL SCIENCES, International Edition demystifies and fully explains statistics without leaving out relevant topics or simply presenting formulas, in a format that is non-threatening and inviting to students. The author's clear, patiently crafted explanations, with an occasional touch of humor, teach students not only how to compute an answer, but also why they should perform the procedure or what their answer reveals about the data. The book achieves several objectives: it presents a conceptual-intuitive approach, presents statistics within an understandable research context, deals directly and positively with student weaknesses in mathematics, and introduces new terms and concepts in an integrated way. The result is a text that students can learn from as well as enjoy.

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.

The presentation of mental illness at work has different implications and consequences depending on the specific nature of the job, work context, regulatory framework and risks for the employee, organisation and society. Naturally there are certain occupational groups where human factors and/or mental illness could impair safety and mental acuity, and with potentially devastating consequences. For pilots, the medical criteria for crew licensing are stipulated by regulatory aviation authorities worldwide, and these include specific mental illness exclusions. The challenge of assessment for mental health problems is, however, complex and the responsibility for psychological screening and testing falls to a range of different specialists and groups including AMEs (authorised aviation medical examiners), GPs and physicians, airline human resources departments, psychologists, human factor specialists and pilots themselves. Extending and developing the ideas of Aviation Mental Health (2006), which described a range of psychological issues and problems that may affect pilots and the consequences of these, this book presents an authoritative, comprehensive and practical guide to modern, evidence-based practice in the field of mental health assessment, treatment and care. It features contributions from experts in the field drawn from several countries, professions and representing a range of aviation-related organisations, displaying a range of different skills and methods that can be used for the clinical assessment of pilots and in relation to specific mental-health problems and syndromes.

Glena Iten investigates the impact of interactive visual simulations on conceptual understanding of statistical principles. Overall, all students were able to increase their knowledge by working with visual simulations, whereas students who could manipulate statistical graphs in the simulation on their own were significantly faster. Currently, interactive learning tools explaining statistical concepts are widely spread, but only few are tested. Well-structured interactive learning programs with visual simulations have in the past been shown to be effective. By applying effective instructional design principles, an online tutorial where students could either manipulate or only observe changes in the visual simulations, was developed. Practical implications and opportunities for further investigations in this research project are discussed.

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.

In today's rapidly changing and information-rich world, students are not acquiring adequate knowledge and skills to prepare them for careers in mathematics, science, and technology with the traditional approach to assessment and instruction. New competencies (e.g., information communication and technology skills) are needed to deal successfully with the deluge of data. In order to accomplish this, new "educationally valuable" skills must be acknowledged and assessed. Toward this end, the skills we value and support for a society producing knowledge workers, not simply service workers, must be identified, together with methods for their measurement. Innovative Assessment for the 21st Century explores the faces of future assessment-and ask hard questions, such as: What would an assessment that captures all of the above attributes look like? Should it be standardized? What is the role of the professional teacher?

The rapid social change in the East Asia has brought great research attention on the family, education and political impacts. The growth trajectory of the next generation is exposed to an entirely different context owing to the dual effects of traditional and modern values as well as practices. This book provides an overall picture of the developmental trajectory of Taiwanese youth as a typical example in the region. The time frame is set from early adolescence (13years old) to young adulthood (22yeard old). Individual psychological well-being in its broad definition will be used as the outcome indicator to reflect significant developmental processes during this important transitional life course. Benefitted from the rare panel datasets conducted from 2000-2009, this book has two major focuses: one is to explore the interplay among family, school and community with regard to their influence on the individual growth patterns; the other is to highlight the potential constraint and/or strength of the prevailing social norms and values shared among East Asian societies. To be specific, different chapters will describe and analyze the life chances and growth patterns among youth with different social capitals (including family SES, educational achievement, rural-urban residence, etc.). Their short-term versus long-term outcome, as indicated by various psychological well-being variables (e.g., depressive symptoms, deviant or problem behaviors, happiness, edutional performance), will allow us to delineate the particular structural context that individual East Asian youth encounters and to offer constructive suggestions on family interaction, educational strategy as well as health related policies based on the scientific evidence. This book incorporates comparative reports from other East Asian societies, and from youth panel studies of Australia and the U.S.. The experience of their counter-part in the advanced societies will contribute to readers' understanding of the particular social situation that East Asian youth is embedded in the growth process. In addition, comparative perspective will enable the reader to contemplate on the potential future development of the affluent generation in the region. Since changing social structure occurred in the last few decades in the East Asia has suffered inadequate investigation in the realm of family, education and community, this book provides timely information to fill up the gap. Analyses of the valuable dataset from early adolescents to young adults will attract those who are interested in family researches, in youth studies, in panel data analyses, as well as in the social development in Taiwan and in East Asia.

The source of endless speculation and public curiosity, our scientific quest for the origins of human consciousness has expanded along with the technical capabilities of science itself and remains one of the key topics able to fire public as much as academic interest. Yet many problematic issues, identified in this important new book, remain unresolved. Focusing on a series of methodological difficulties swirling around consciousness research, the contributors to this volume suggest that 'consciousness' is, in fact, not a wholly viable scientific concept. Supporting this 'eliminativist' stance are assessments of the current theories and methods of consciousness science in their own terms, as well as applications of good scientific practice criteria from the philosophy of science. For example, the work identifies the central problem of the misuse of qualitative difference and dissociation paradigms, often deployed to identify measures of consciousness. It also examines the difficulties that attend the wide range of experimental protocols used to operationalise consciousness-and the implications this has on the findings of integrative approaches across behavioural and neurophysiological research. The work also explores the significant mismatch between the common intuitions about the content of consciousness, that motivate much of the current science, and the actual properties of the neural processes underlying sensory and cognitive phenomena. Even as it makes the negative eliminativist case, the strong empirical grounding in this volume also allows positive characterisations to be made about the products of the current science of consciousness, facilitating a re-identification of target phenomena and valid research questions for the mind sciences.

This book provides first time insight into whether emotions impact performance of an online ability test. This question is gaining in relevance as online assessment is used increasingly in personnel selection and since it has been shown that emotions impact the way humans think. Moreover, the author demonstrates, for the first time, how short film clips can elicit different emotions in an online setting. Furthermore, she gives an overview of the area of online assessment, of models of intelligence and emotion, and of how emotion and cognition interact.

Jung's Personality Theory Quantified fills an urgent need for professionals using the Myers-Briggs Type Indicator (R) (MBTI) to map it on to the cognitive modes of Jung's personality theory, avoiding potential logical errors in the traditional "type dynamics" method. It furthers Jung's original concepts while placing them on a solid axiomatic basis not possessed by other personality theories. Bringing these quantitative findings to the millions of MBTI users - managers, consultants, counsellors, teachers, psychoanalysts and human resource professionals - will require further education of those already certified to administer the instrument according to type dynamics. For this reason numerical exercises follow most chapters to make the book a source reference for briefer workbooks usable in enhanced certification programs. Backed by quantitative theory and new graphical methods, the pioneering qualitative typology work of Myers and Briggs is thus extended to yield deeper understanding of the vital topics of human personality, creativity and human relations. Jungian psychoanalysts may find Jung's Personality Theory Quantified helpful in organizing complicated clinical information and it can also enhance the work of MBTI practitioners worldwide.

Up-to-date coverage of most micro-econometric topics; first half parametric, second half semi- (non-) parametric Many empirical examples and tips in applying econometric theories to data Essential ideas and steps shown for most estimators and tests; well-suited for both applied and theoretical readers

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.

The field of psychometrics has a long and varied tradition across the social sciences. A range of academics have sought to understand human consciousness more fully by statistical testing our abilities, personalities, attitudes and beliefs. But perhaps the area where psychometric techniques have had most impact on contemporary society is in employee recruitment, where a range of psychometric tests have become common-place. Professor Peter Saville is one of the pioneers of adapting psychometric testing to the field of occupational psychology and human resource management. In a career of nearly 40 years, his work has been adopted by hundreds of public and private organizations, assessing the suitability of prospective candidates through a range of questionnaires and tests. In this anthology of his work, including both keynote conference address and journal papers, Saville provides a masterly overview of the field of psychometrics, and the key issues and questions that it raises. An ideal companion for any student or researcher of HRM, occupational or organizational psychology, or applied psychology in general, Peter Saville's selected works represent the thinking of one of the most influential psychologists of our time.

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!

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.
