Book Description
Whereas the cerebral specialization for skilled manual actions (praxis) seems closely linked to dominance for language, with both functions left lateralized in the vast majority of humans, the neural correlates of hand preference are still less well understood. Indeed, as a combination of inherited and non-inherited genomic factors (i.e., direct parental and concealed environmental contributions), handedness – in contrast to language – is less likely to have strong genetic indices and clearly lateralized functional organization. What about eye dominance, unimanual and bimanual object manipulation, and gestures, or attentional systems and the related egocentric or allocentric coding of space? Are these different categories functionally and structurally interconnected? Is their development and contribution to task performance linked, even if they are differently lateralized? How are they connected to language learning or its development? In trying to understand these relationships and their neural underpinnings we obtain a new insight into fundamental human behaviors, which depend either on shared or distinct cerebral resources that must, nevertheless, be harmonized by higher-order cerebral processing. In this Research Topic we assembled a dozen of original research contributions, as well as articles with more theoretically-driven perspectives, that directly speak to these issues. Hopefully this work will serve as a foundation for further discussions and will stimulate new research in this fascinating domain.

Book Description
This book represents a broad integration of several major themes in psychology toward its unification. Unifying psychology is an ongoing project that has no end-point, but the present work suggests several major axes toward that end, including causality and activation-inhibition coordination. On the development side of the model building, the author has constructed an integrated lifespan stage model of development across the Piagetian cognitive and the Eriksonian socioaffective domains. The model is based on the concept of neo-stages, which mitigates standard criticisms of developmental stage models. The new work in the second half of the book extends the primary work in the first half both in terms of causality and development. Also, the area of couple work is examined from the stage perspective. Finally, new concepts related to the main themes are represented, including on the science formula, executive function, stress dysregulation disorder, inner peace, and ethics, all toward showing the rich potential of the present modeling.

Book Description
The growth of clinical neuropsychology has been unprecedented. This growth has been oriented more toward the provision of than toward the foundation for services. Thus, while a greater number of psychologists are performing a greater number of neuropsychological procedures, there seems to us an uneven parallel growth between these services and the empirical foundations for them. It should come to no one's surprise that increasingly aggressive attacks on the field have been leveled. Despite these attacks, clinical neuropsychology con tinues to enjoy exceptional growth within psychology and acceptance by other health practitioners, insurance companies, legislators, judges, juries, and above all, consumers of our services. Growth without self-reflection is a dangerous enterprise, as is growth without directions. We find it disconcerting that existing and limited "self analysis" has assumed that neuropsychological dysfunction is immune to the same variables that affect psychological dysfunction. Some attention has been paid to the most obvious ones, such as age, but all others have been ignored and/ or misunderstood. This neglect has spawned a body of knowledge replete with questionable data and unfounded conclusions. Hence, it is surprising that clinical neuropsychologists consider themselves to be more scientifically sound than their regular clinical counterparts.

Book Description
Discussed in this book is the association between speech and movements, especially those of the preferred hand. Both are skilled motor activities that appear to depend upon a similar neural organization that is available in the left hemisphere of the brain. The nature of this association of the cerebral control of speech and skilled manual performance is discussed in four sections: 1. Motor control and speech examines speech as a motor activity2. Language and gesture examines the correspondence between spoken language and manual gesture3. Motor performance and aphasia examines the motor impairments associated with aphasias4. Interactions of speech and manual performance examines the interactions that occur between concurrent verbal and manual activities

Book Description
Neural Plasticity Across the Lifespan reviews the recent scientific developments which are transforming our understanding of the human brain. For many years it was thought that modifications to the structural and functional organization of the brain were limited to a short early period of life, "the critical period", and, in adults, to the memory system. Recent research suggests that on the contrary we should see the human brain as a flexible structure, which adapts and modifies in response to learning, sensory experience, age and disease. The book provides an integrated overview of contemporary research on neural plasticity - the process by which the brain can change in structure and function to cope with new experiences and react to the effects of acquired damage or sensory deprivation. It reviews data on plasticity in the developing brain, looking at both typical and atypical development, alongside clinical and observational research on the adult population. It covers a number of key topics, including: different forms of neural plasticity factors affecting neural plasticity (ageing and gender), neural plasticity in language acquisition, memory and bodily self-consciousness mechanisms of repair – plasticity following sensory deprivation and acquired brain damage. This is an accessible overview of an emerging field of research which has fundamental implications for how we perceive our potential to change throughout our lives. It will be essential reading for all students of cognitive development, cognitive neuroscience and lifespan development.

Book Description
Differential psychology, or the psychology of individual differences as it is better known, is perhaps the single most important basic psychological science that underlies professional practice in psychology. The recent age of behaviorism all but ignored individual differences, but in this decade the study has emerged from relative dormancy with a new vitality, fueled by new concepts, technologies, statistics, and new viewpoints on old ideas that are moving us forward. This work is intended to be a review of as well as a primer on many of these advances and new approaches to the study of individual differences. The venerable, interesting, and often controversial Eysenck opens the volume with a review of recent results and new techniques for unlocking the physiological basis of what is commonly understood to be intelligence. Eysenck and his students, in his London laboratory, have been fostering advances in this field for more than four decades. Their latest work could be the most exciting of Eysenck's illustrious, scholarly career. Eysenck's eye-opening, innovative work on the relationship between evoked potentials and performance on traditional psychometric measures, presented with a new slant, is certain to attract much attention in coming years. Eysenck and Barrett's chapter is followed by a closely related work by Arthur Jensen, who gives us a revitalizing look at the concepts of Sir Francis Galton, the founder of the psychology of individual differences.

Book Description
Bringing together leading experts--and providing vital insights to guide clinical practice--this is the first volume to comprehensively address childhood motor disorders from a neuropsychological perspective. The book explores the neural and behavioral bases of movement disorders and summarizes current findings from applied research. Existing approaches to assessment and neuroimaging are critically examined, and new and innovative methods presented. Authors also synthesize the latest knowledge on motor difficulties associated with specific developmental and neurological problems: cerebral palsy; neuromuscular disease; autism; brain injury; disorders of coordination, speech, and written language; and more. Other important topics covered include psychosocial effects of motor skills impairments, frequently encountered comorbidities, and the status of available intervention approaches.

Book Description
Brain asymmetry for speech is moderately related to handedness but what are the rules? Are symmetries for hand and brain associated with characteristics such as intelligence, motor skill, spatial reasoning or skill at sports? In this follow up to the influential Left, Right Hand and Brain (1985) Marian Annett draws on a working lifetime of research to help provide answers to crucial questions. Central to her argument is the Right Shift Theory - her original and innovative contribution to the field that seeks to explain the relationships between left-and right-handedness and left-and right-brain specialisation. The theory proposes that handedness in humans and our non-human primate relations depends on chance but that chance is weighted towards right-handedness in most people by an agent of right-hemisphere disadvantage. It argues for the existence of a single gene for right shift (RS+) that evolved in humans to aid the growth of speech in the left hemisphere of the brain. The Right Shift Theory has possible implications for a wide range of questions about human abilities and disabilities, including verbal and non verbal intelligence, educational progress and dyslexia, spatial reasoning, sporting skills and mental illness. It continues to be at the cutting edge of research, solving problems and generating new avenues of investigation - most recently the surprising idea that a mutant RS+ gene might be involved in the causes of schizophrenia and autism. Handedness and Brain Asymmetry will make fascinating reading for students and researchers in psychology and neurology, educationalists, and anyone with a keen interest in why people have different talents and weaknesses.

Book Description
Reading this volume, chapter by chapter, I had a feeling of exuberance and exhiliration. lt is both a privilege and achaIlengc 10 write a foreword for this second edition of Learning Disahilities and Brain Function. The scope and quality of the scientific and clinical insights expressed are unusual. It is difficult to do justice 10 the book within the constraints of a foreword. I can only reftect its significance to instructors, scientists. and clinicians in education, psychology, psychiatry. pediatrics. speech pa thology and neurology. In the early chapters are discussions of brain function as it relates to learning and learning disabilities, with many implications for better undcr standing of the neurology of behavior. These chapters are followcd by an articulate consideration of neuropsychological disorders, definition. iden tification and diagnosis of the cognitive dysfunctions that underlie learn ing disabilities. There is an analysis of the role of perception, as weIl as of the significance of impared sensory and motor-cognitive processes. The concluding chapters comprise a clear, erudite, yet practical dis course on the spectrum of language disorders, including the spoken, read, and writ ten forms. Dr. Gaddes provides a constructive review of what it means when children have aphasia, of how this language disorder has implica tions for other types of learning. He elucidates and evaluates the status of our knowledge relative to childhood dyslexia and dysgraphia. This analy sis holds promise for clarification of the issues that have been disconcert ing, especially to educators and psychologists.
