An increase in research into all facets of learning difficulties has resulted in a deeper understanding of the problems. This book includes a description and explanation of reading, spelling and learning difficulties; provides chapters on psychological and neuropsychological assessment; explains the associations between behavioural problems and learning difficulties; and critically reviews remedial approaches, incorporating a summary of what is known about their efficacy. The importance of dealing with attendant behavioural problems and the significance of phonological knowledge in literacy learning are central themes.; Intended to be a succinct and accessible synthesis of current knowledge in this area, this book should be of interest to professionals who encounter children with learning difficulties, tertiary students and parents.

This concise guide offers an accessible introduction to genes, fetal development and early brain development. It integrates insights from typical and atypical development to reveal fundamental aspects of human growth and development, and common developmental disorders. The topic books in this series draw on international research in the field and are informed by biological, social and cultural perspectives, offering explanations of developmental phenomena with a focus on how children and adolescents at different ages actually think, feel and act. In this succinct volume, Stephen von Tetzchner explains key topics including: Genetic inheritance, evolution, heredity and environment in individual differences, fetal development, prenatal stimulation, methods of studying the brain, brain development, early and later plasticity and brain organization and atypical development. Together with a companion website that offers topic-based quizzes, lecturer PowerPoint slides and sample essay questions, Typical and Atypical Child and Adolescent Development 2: Genes, Fetal Development and Early Neurological Development is an essential text for all students of developmental psychology, as well as those working in the fields of child development, developmental disabilities and special education.

Emotions, behaviors, thoughts, creations, planning, daily physical activities, and routines are programmed within our brains. To acquire these capacities, the brain takes time to fully develop--a process that may take the first 20 years of life. Disruptions of the brain involving neurons, axons, dendrites, synapses, neurotransmitters or brain infrastructure produce profound changes in development and functions of the one organ that makes us unique. To understand the functions and development of the brain is difficult enough, but to reverse the consequences of trauma and repair the damage is even more challenging. To meet this challenge and increase understanding, a host of disciplines working and communicating together are required.
The International Association for the Study of Traumatic Brain Injury tried to correct this limitation during its meetings of international clinicians, researchers, and scientists from many fields. It was felt that many of the outstanding thoughts and ideas from the participants' most recent meeting and from others working in the field of traumatic brain injury (TBI) should be shared. This book was conceived not as proceedings of the conference, but as a collection of knowledge for those working in the acute and chronic recovery aspects of head injury.
This book reflects the importance of the team approach to patients with TBI. The chapter authors come from a diverse array of disciplines--basic science, neurosurgery, neurology, radiology, psychology, neuropsychology, and legal, consumer, and speech/language science. Their contributions provide the most current research and the latest ways of managing a variety of aspects of TBI.

Conceived at a time when biological research on aggression and violence was drawn into controversy because of sociopolitical questions about its study, this volume provides an up-to-date account of recent biological studies performed -- mostly on humans. A group of scientists recognized the importance of freedom of inquiry and deemed it vital to address the most promising biological research in the field. The focus on biological mechanisms is not meant to imply that biological variables are paramount as a determinant of violence. Rather, biological variables operate in conjunction with other variables contributing to aggression or violence, and a complete understanding of this phenomenon requires consideration of all influences bearing on it.
This book will familiarize readers with the rapidly growing and increasingly significant body of knowledge on the biological bases of human antisocial, aggressive, and violent behaviors. The editors concentrated on biological influences that support the basic physiological and biochemical processes of the brain and did not cover those biological influences that impact on the health of the individual such as head injury, pregnancy and birth complications, diet, and exposure to lead and other toxins. They focused on biological influences to illuminate their role in the complex behavioral phenomenon of violence.
Three different approaches to the biological study of human antisocial, aggressive, and violent behaviors are represented -- genetic, neurobiological, and biosocial. Representing each of these three approaches, individual chapters from investigators in psychobiology, biological psychiatry, and basic-clinical neurosciences address the most recent experimental findings, methods, theory, and common misconceptions in the biological study of aggression and violence. The areas of primary focus are behavior and molecular genetics, neurochemistry and hormones, neuroimaging, psychophysiology and developmental psychobiology. Generally speaking, investigators following these different approaches have experience in different scientific backgrounds, select different methods, generate different analyses, employ different conceptual definitions for some of the same terms, and assume a different philosophical stance in attempting to explain violence. Nevertheless, all are united in their efforts to understand the biological underpinnings of violence. This book then assumes a comprehensive approach wherein different levels of analysis and different approaches inform each other. It is clear from the studies reported that aggression and violence are multidetermined phenomena and understanding them requires an interdisciplinary approach spanning economic, sociopolitical, psychological, sociological, and criminological as well as biomedical considerations. Nature (biology) and nurture (experience, context) are fundamentally inseparable in explaining aggression and violence; biology may affect experience or context, but experience or context also influences biology. Both need to be studied in a search for explanations of this phenomena.

The case study of John has provided a unique insight into the nature of visual agnosia and more broadly into the underlying processes which support human vision. After suffering a stroke, John had problems in recognizing common objects, faces, seeing colours, reading and finding his way around his environment. A Reader in Visual Agnosia brings together the primary scientific papers describing the detailed investigations for each visual problem which the authors carried out with John, known as patient HJA. This work was summarised initially in To See But Not To See (1987), and 26 years later in A Case Study in Visual Agnosia Revisited (2013). The chapters are divided into 6 parts corresponding to the key areas of investigation: Integrative visual agnosia Perception of global form Face perception Colour perception Word recognition Changes over time Each part contains a short introduction, written by the two leading researchers who worked with John, which highlights the relations between the papers and demonstrates the pathway of the case analysis. The book will be invaluable to students and researchers in visual cognition, cognitive neuropsychology and vision neuroscience.

Signal detection theory--as developed in electrical engineering and based on statistical decision theory--was first applied to human sensory discrimination 40 years ago. The theoretical intent was to provide a valid model of the discrimination process; the methodological intent was to provide reliable measures of discrimination acuity in specific sensory tasks. An analytic method of detection theory, called the relative operating characteristic (ROC), can isolate the effect of the placement of the decision criterion, which may be variable and idiosyncratic, so that a pure measure of intrinsic discrimination acuity is obtained. For the past 20 years, ROC analysis has also been used to measure the discrimination acuity or inherent accuracy of a broad range of practical diagnostic systems. It was widely adopted by methodologists in the field of information retrieval, is increasingly used in weather forecasting, and is the generally preferred method in clinical medicine, primarily in radiology. This book attends to both themes, ROC analysis in the psychology laboratory and in practical diagnostic settings, and to their essential unity.
The focus of this book is on "detection" and "recognition" as fundamental tasks that underlie most complex behaviors. As defined here, they serve to distinguish between two alternative, confusable stimulus categories, which may be perceptual or cognitive categories in the psychology laboratory, or different states of the world in practical diagnostic tasks.
This book on signal detection theory in psychology was written by one of the developers of the theory, who co-authored with D.M. Green the classic work published in this area in 1966 (reprinted in 1974 and 1988). This volume reviews the history of the theory in engineering, statistics, and psychology, leading to the separate measurement of the two independent factors in all discrimination tasks, discrimination acuity and decision criterion. It extends the previous book to show how in several areas of psychology--in vigilance and memory--what had been thought to be discrimination effects were, in reality, effects of a changing criterion.
The book shows that data plotted in terms of the relative operating characteristic have essentially the same form across the wide range of discrimination tasks in psychology. It develops the implications of this ROC form for measures of discrimination acuity, pointing up the valid ones and identifying several common, but invalid, ones. The area under the binormal ROC is seen to be supported by the data; the popular measures "d'" and percent correct are not. An appendix describes the best, current programs for fitting ROCs and estimating their parameters, indices, and standard errors.
The application of ROC analysis to diagnostic tasks is also described. Diagnostic accuracy in a wide range of tasks can be expressed in terms of the ROC area index. Choosing the appropriate decision criterion for a given diagnostic setting--rather than considering some single criterion to be natural and fixed--has a major impact on the efficacy of a diagnostic process or system. Illustrated here by separate chapters are diagnostic systems in radiology, information retrieval, aptitude testing, survey research, and environments in which imminent dangerous conditions must be detected. Data from weather forecasting, blood testing, and polygraph lie detection are also reported. One of these chapters describes a general approach to enhancing the accuracy of diagnostic systems.

Originally published in 1977, the objective of this book was to examine the mechanisms by which the multiple factors or determinants - homeostatic deficits, hormonal influences, circadian rhythms, experiential and cognitive factors - become translated by the central nervous system into thermoregulatory, feeding, sexual, aggressive, and other behaviours. A conceptual framework has been used that reflects relevant contributions from biology, regulatory physiology, physiological psychology, and other neuroscience disciplines. The final chapter deals with difficulties in brain-behaviour research in relation to experimental strategies and with crucial problems for future investigation.

Alcohol abuse is a major health problem in most parts of the world. This book focuses on the way in which alcohol affects the brain, with the aim of describing advances in the neuropsychology of alcoholism in a way that makes this work accessible to clinicians from a variety of backgrounds who treat people with alcohol-related problems.; The book is divided into four parts. Part One provides an introduction to the medical and neurological conditions that can result from alcoholism, and to the process of neuropsychological assessment. The problems involved in conducting research in this area are also considered. In Part Two, research that focuses directly on changes to the nervous system is surveyed. This includes studies of both the short-term and the chronic neurological changes in the brain caused by alcohol. In Part Three, studies of the neuropsychological effects of acute intoxication, social drinking and alcohol abuse are described. Finally, in Part Four, the implications of neuropsychological research for the assessment and management of patients with alcohol problems are considered.; The objective of this book is to collate the range of research work that is relevant to understanding how alcohol affects the brain. This includes both the acute and the chronic effects, at both the biological and physiological levels.

We are profoundly social creatures - more than we know.
In "Social," renowned psychologist Matthew Lieberman explores groundbreaking research in social neuroscience revealing that our need to connect with other people is even more fundamental, more basic, than our need for food or shelter. Because of this, our brain uses its spare time to learn about the social world - other people and our relation to them. It is believed that we must commit 10,000 hours to master a skill. According to Lieberman, each of us has spent 10,000 hours learning to make sense of people and groups "by the time we are ten."
"Social" argues that our need to reach out to and connect with others is a primary driver behind our behavior. We believe that pain and pleasure alone guide our actions. Yet, new research using fMRI - including a great deal of original research conducted by Lieberman and his UCLA lab -- shows that our brains react to social pain and pleasure in much the same way as they do to physical pain and pleasure. Fortunately, the brain has evolved sophisticated mechanisms for securing our place in the social world. We have a unique ability to read other people's minds, to figure out their hopes, fears, and motivations, allowing us to effectively coordinate our lives with one another. And our most private sense of who we are is intimately linked to the important people and groups in our lives. This wiring often leads us to restrain our selfish impulses for the greater good. These mechanisms lead to behavior that might seem irrational, but is really just the result of our deep social wiring and necessary for our success as a species.
Based on the latest cutting edge research, the findings in "Social" have important real-world implications. Our schools and businesses, for example, attempt to minimalize social distractions. But this is exactly the wrong thing to do to encourage engagement and learning, and literally shuts down the social brain, leaving powerful neuro-cognitive resources untapped. The insights revealed in this pioneering book suggest ways to improve learning in schools, make the workplace more productive, and improve our overall well-being.

This is a very unusual book. It brings to the English speaking reader a masterpiece written some 50 years ago by one of the greatest minds of the 20th century--Nicholai Aleksandrovich Bernstein--considered the founder of many contemporary fields of science such as biomechanics, motor control, and physiology of activity. Divided into two parts, this volume's first section is a translation of the Russian book "On Dexterity and Its Development." It presents, in a very reader-friendly style, Bernstein's major ideas related to the development and control of voluntary movements in general, and to the notion of dexterity, in particular. Although very few scientific works remain interesting to the reader 50 years after they were written, this volume--now available for the first time in English--is a rare exception to this rule. His ideas are certainly not obsolete. Actually, we are just starting to grasp the depth and breadth of his thinking, especially his analysis of the complex notion of dexterity. The second section provides both a historical and a contemporary perspective on Bernstein's ideas.
The original work was directed at a wide audience ranging from specialists in biomechanics and motor behavior, to coaches, neurologists, physical therapists, athletes, and even inquisitive college and high school students. The chapters contributed by contemporary scientists mirror Bernstein's style and present new findings in the areas of biomechanics, motor control, and motor development in a way that would be both understandable to non-specialists in these areas, and informative for professionals working in different areas related to human movement. All those interested in the origins and mechanisms of the production of voluntary movements, irrespective of their educational and professional background, will find this book valuable. In addition, the unique history and composition of this text will make it helpful and attractive to historians and philosophers of science.

Devoted exclusively to prospective memory, this volume organizes the research and thoughts of the important contributors to the field in one comprehensive resource. The chapter authors not only focus on their own work, but also review other research areas and address those where the methods and theories from the retrospective memory literature are useful and where they fall short. Each section is followed by at least one commentary written by a prominent scholar in the field of memory. The commentators present critical analyses of the chapters, note ideas that they found particularly exciting, and use these ideas as a foundation on which to elaborate their own views of prospective memory.
This volume will stimulate the thinking of active prospective memory researchers, provide a coherent organization of the area for the increasing number of people who are interested in prospective memory but who are not yet actively conducting research in the area, and serve as a book of readings for upper division seminars.

Emotion is something we all talk about in everyday conversations, and studies make an implicit assumption that emotions are "out there" or "in there", somewhere in psychological reality waiting to be isolated and dissected. Brian Parkinson looks at emotion in encounters between people, expressed in gesture and movement, talk and silence. He presents a clear and concise overview of research into emotion focusing on cognitive appraisal, bodily changes, action tendencies and expressive displays. This text challenges the idea of emotion as an individual intrapsychic phenomenon, and formulates a conceptual framework based on the idea of emotion as interpersonal communication, a social practice influenced by culture and language. The book should prove valuable to all those approaching emotion from a social psychological perspective, whether at advanced undergraduate or graduate level.

In a wide array of social sciences, interest in emotion is flourishing. Psychologists, sociologists, anthropologists, communication scholars, and cognitive scientists are exploring human emotions in a variety of contexts. This book speaks to central issues raised by scholars in these disciplines through its review of leading cognitive appraisal theories of emotion, clarification of the nature of empathy, and exploration of how people identify and respond to the emotions hidden within the stories people tell.
Intrigue with the separateness and oneness of human existence and experience is evident throughout history. It appears in the teachings of all great religions, in the commentaries of philosophers, and in the perceptions of the most famous characters in classic literature. Perhaps it is this wonderment with human distinction and unity that has spawned interest in empathy as a pervasive human phenomena.
This book presents an initial examination of the role of cognitive appraisals in facilitating decoding accuracy and empathy. It compares the leading cognitive appraisal theories and addresses the relationships among appraisal information, empathy, and emotion decoding. Real-life descriptions of emotional experiences are used as the basis for a study examining the relationships between perceived appraisals and perspective-taking, and accurate decoding and empathy. Other studies probe the effects of specific appraisal information on decoding and emotional reactions, and address emotional reactivity to stories and delayed retention. Finally, specific applications are offered for parents, educators, social service employees, writers, advertisers, and people striving for personal well-being and healthy relationships.

This little book is not a text-book of psychology. It is exclusively concerned with one particular psychological problem, a problem, however, that stands at the very centre of psychology. The relations between mind and body are analysed; that is to say, the following three psychedelic problems are successively raised: What is the mind? What is the body? What are the relations between mind and body? But it is only the third problem which is extensively dealt with; the first two are only briefly defined.

First published in 1993. This book is intended for managers and occupational psychologists involved in the selection and assessment of the workforce. It details the history and development of the use of biographical data for both recruitment and promotion of employees. Grounded in relevant research literature, it offers a comprehensive analysis of the advantages and disadvantages of biodata in different contexts. It also includes examples of applications and recommendations for use, as well as examples of questionnaires. Written by experts, it represents a wide-ranging review of the contemporary research in the field. This work will be of interest to students of business and psychology.

In this collection of essays, the four branches of radical cognitive science-embodied, embedded, enactive and ecological-will dialogue with performance, with particular focus on post-cognitivist approaches to understanding the embodied mind-in-society; de-emphasising the computational and representational metaphors; and embracing new conceptualisations grounded on the dynamic interactions of "brain, body and world". In our collection, radical cognitive science reaches out to areas of scholarship also explored in the fields of performance practice and training as we facilitate a new inter- and transdisciplinary discourse in which to jointly share and explore common reactions of embodied approaches to the lived mind. The essays originally published as a special issue in Connection Science.

Based on a conference held in honor of Professor Tarow Indow, this volume is organized into three major topics concerning the use of geometry in perception:
* space -- referring to attempts to represent the subjective space within which we locate ourselves and perceive objects to reside;
* color -- dealing with attempts to represent the structure of color percepts as revealed by various experimental procedures; and
* scaling -- focusing on the organization of various bodies of data -- in this case perceptual -- through scaling techniques, primarily multidimensional ones.
These topics provide a natural organization of the work in the field, as well as one that corresponds to the major aspects of Indow's contributions. This book's goal is to provide the reader with an overview of the issues in each of the areas, and to present current results from the laboratories of leading researchers in these areas.

This book describes a unique combination of research programs based on a striking variety of hypotheses and procedures directed toward understanding the sources and consequences of neurobehavioral plasticity. This remarkable attribute of the nervous system -- to be pliable and capable of being shaped or formed by natural or artificial sources toward adaptation or maladaptation -- is considered in terms of the neurochemical forces and neuroanatomical structure that has been found to be pivotal for this function. The impetus for this volume was a symposium held to honor Robert L. Isaacson for his scientific and pedagogical achievements as well as his contributions to behavioral neuroscience.
Corresponding to his three major research interests, the book is divided into three sections as follows:
* the first explores the relationship between the limbic system and behavior, with an emphasis on learning and memory;
* the second considers -- through a wide range of approaches -- issues of plasticity in behavior and brain; and
* the third deals with neural and chemical determinants of normal and abnormal behavior.
This volume is not only a fitting tribute to Isaacson, but also an unusual collection of new evidence, procedures, and theories destined to have significant influence on behavioral neuroscience.

Most military researchers who have attempted to measure organizational commitment have done so on an ad hoc basis, preferring to invent new items and scales rather than incorporate well-established measures. The purpose of this special issue is to reverse this trend by bringing military organizational commitment research into the scientific mainstream and to do so in ways that will prove useful to military services while advancing organizational commitment theory and knowledge. This special issue grew out of a symposium conducted at the 1998 American Psychological Association Convention that arose when many in the field recognized the practical importance of measuring organizational commitment while maintaining a healthy concern for ensuring that this measurement was well-grounded in organizational commitment theory. Taken together, the articles in this issue demonstrate the concepts of affective and continuance commitment and their underlying measures by using them in different military samples and under a variety operational conditions.

Neurotechnology and Direct Brain Communication focuses on recent neuroscientific investigations of infant brains and of patients with disorders of consciousness (DOC), both of which are at the forefront of contemporary neuroscience. The prospective use of neurotechnology to access mental states in these subjects, including neuroimaging, brain simulation, and brain computer interfaces, offers new opportunities for clinicians and researchers, but has also received specific attention from philosophical, scientific, ethical, and legal points of view. This book offers the first systematic assessment of these issues, investigating the tools neurotechnology offers to care for verbally non-communicative subjects and suggesting a multidisciplinary approach to the ethical and legal implications of ordinary and experimental practices. The book is divided into three parts: the first and second focus on the scientific and clinical implications of neurological tools for DOC patient and infant care. With reference to these developments, the third and final part presents the case for re-evaluating classical ethical and legal concepts, such as authority, informed consent, and privacy. Neurotechnology and Direct Brain Communication will appeal to researchers and postgraduate students in the fields of cognitive science, medical ethics, medical technology, and the philosophy of the mind. With implications for patient care, it will also be a useful resource for clinicians, medical centres, and health practitioners.

This volume presents a state-of-the-science review of the most promising current European research -- and its historic roots of research -- on complex problem solving (CPS) in Europe. It is an attempt to close the knowledge gap among American scholars regarding the European approach to understanding CPS. Although most of the American researchers are well aware of the fact that CPS has been a very active research area in Europe for quite some time, they do not know any specifics about even the most important research. Part of the reason for this lack of knowledge is undoubtedly the fact that European researchers -- for the most part -- have been rather reluctant to publish their work in English-language journals.
The book concentrates on European research because the basic approach European scholars have taken to studying CPS is very different from one taken by North American researchers. Traditionally, American scholars have been studying CPS in "natural" domains -- physics, reading, writing, and chess playing -- concentrating primarily on exploring novice-expert differences and the acquisition of a complex skill. European scholars, in contrast, have been primarily concerned with problem solving behavior in artificially generated, mostly computerized, complex systems. While the American approach has the advantage of high external validity, the European approach has the advantage of system variables that can be systematically manipulated to reveal the effects of system parameters on CPS behavior. The two approaches are thus best viewed as complementing each other.
This volume contains contributions from four European countries -- Sweden, Switzerland, Great Britain, and Germany. As such, it accurately represents the bulk of empirical research on CPS which has been conducted in Europe. An international cooperation started two years ago with the goal of bringing the European research on complex problem solving to the awareness of American scholars. A direct result of that effort, the contributions to this book are both informative and comprehensive.

This monograph from a leading neuroscientist and neural networks researcher investigates and offers a fresh approach to the perplexing scientific and philosophical problems of minds and brains. It explains how brains have evolved from our earliest vertebrate ancestors. It details how brains provide the basis for successful comprehension of the environment, for the formulation of actions and prediction of their consequences, and for cooperating or competing with other beings that have brains. The book also offers observations regarding such issues as:
* how and why people fall in and out of love;
* the biological basis for experiencing feelings of love and hate; and
* how music and dance have provided the ancestral technology for forming social groups such as tribes and clans.
The author reviews the history of the mind-brain problem, and demonstrates how the new sciences of behavioral electrophysiology and nonlinear dynamics -- combined with the latest computer technology -- have made it possible for us to observe brains in action. He also provides an answer to the question: What happens to a stimulus after it enters the brain? The answer: The stimulus triggers the construction of a percept and is then washed away. All that we know is what our brains construct for us by neurodynamics. Brains are not logical devices that process information. They are dynamical systems that create meaning through interactions with the environment -- and each other.
The book shows how the learning process by which brains construct meaning tends to isolate brains into self-centered worlds, and how nature has provided a remedy -- first appearing in mammals as a mechanism for pair-bonding -- to ensure reproduction of the young dependent on parents. The remedy is based in the neurochemistry of sex which serves to dissolve belief structures in order to open the way for new patterns of understanding and behavior. Individuals experience these changes in various ways, such as falling in love, collegiate indoctrination, tribal bonding, brain washing, political or religious conversions, and related types of socialization. The highest forms of meaning for humans come through these social attachments.
