The performance of most tasks with one hand, typically the right, is a uniquely human characteristic. Not only do people prefer to use one hand rather than the other, but also they usually perform tasks faster and more accurately with this hand. The study of manual asymmetries and what such performance differences between the two hands reveal about brain organization and motor function has been a topic of considerable research over the last several decades. The aim of this Research Topic is to review and further explore the origins of manual asymmetries and their relationship to handedness, unimanual and bimanual motor performance, and brain function. The articles included here involve original research conducted in humans or non-human models species, as well as theoretical perspectives, review articles, and meta-analyses.

"Manual asymmetries" refers to differences in performance capabilities of the two hands. Humans may be the only species that show a consistent preference for the right hand.

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.

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.

Functional cerebral specialization is a phenomenon of considerable relevance not only to those investigating normal brain function, but also to scientists who study and treat clinical populations. This special issue of "Laterality" brings together contributions from researchers studying human populations and those using animal models, and includes a discussion of the important issues in the field of lateralization of function. The papers address the origins of laterality and the nature of lateralized functions in various species, as well as relations among the different forms of lateralization. Included are such topics as lateralized memory processes, early experiential effects on laterality, the genetic basis of handedness, perceptual processing in the haptic or visual domain, and learning. Comparisons between human and non-human primate findings and the implications of these findings for our understanding of the phylogenetic basis of hemispheric specialization are also emphasized.; The papers are based on presentations at two symposia that took place in August 1996: "Issues in Laterality", held at the International Congress of Psychology in Montreal; and "Laterality and Hemispheric Specialization in Primates: Brain Behavior and Evolution", held at the University of Wisconsin, Madison, at the joint meetings of the "XVI Congress of the International Primatological Society" and the "XIX Conference of the American Society of Primatologists".

`Rather than being an esoteric aspect of brain function, lateralization is a fundamental characteristic of the vertebrate brain essential to a broad range of neural and behavioral processes.' Professor Lesley J. Rogers, Chapter 1 of Side Bias: A Neuropsychological Perspective. This volume contains 14 chapters from a veritable `United Nations' of experts in the field of lateralization of function. They write comprehensive reviews, present data, and pose new questions concerning the evolutionary origins and development of side bias, methodological concerns with the way we measure handedness and footedness, and some more unusual aspects of human beings' lateralized behavior, such as asymmetrical cradling and pseudoneglect. The book will be essential reading for students of behavioral neuroscience and neuropsychology interested in lateralization of function as well as for established researchers in the field.

Laterality in Sports: Theories and Applications summarizes recent research on the neurophysiological foundations of handedness, and how left or right lateralization (affecting primary hand use, foot use, and eye use) affects motor control, performance outcome, skill acquisition, and achievement of sports expertise—both for one-on-one sports and team sports. As laterality research has matured, greater focus has been given to applications in human endeavours and, in particular, sport. The book examines performance within individual sports, and discusses the coaching ramifications of coaching to a specific lateralization preference. Describes the neurophysiological foundations of handedness Discusses the origins and development of laterality in humans Summarizes the impact of laterality on motor control and sports performance Encompasses research on both individual and team sports Includes research on skill acquisition, coaching, and development of expertise Covers research on laterality in preferred hand, foot, and eye use in sports
