Book excerpt: 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 Synopsis Manual Specialization and the Developing Brain by : Gerald Young

Download or read book Manual Specialization and the Developing Brain written by Gerald Young. This book was released on 2012-12-02. Available in PDF, EPUB and Kindle. Book excerpt: Manual Specialization and the Developing Brain deals with how the hands acquire different skills and what this may tell about the child's developing brain. This book is organized into three parts. Part I provides a general overview of lateralization development, while Part II compiles contributions that are more theoretical in nature. The last part summarizes the empirical research with neonates. This text specifically discusses the studies of early lateralized manual behaviors, character of human handedness, and factors that contribute toward variability in lateralization. The hemisphere differences in response to specific stimulus cues, phylogenetic perspective, and infant motor skills project are also elaborated. This text likewise covers the developmental view of hemispheric specialization and changes and constancies in development. This publication is useful to pediatricians, medical practitioners, and researchers concerned with early lateralized behavior.

Book Synopsis The Hand, an Organ of the Mind by : Zdravko Radman

Download or read book The Hand, an Organ of the Mind written by Zdravko Radman. This book was released on 2013-05-10. Available in PDF, EPUB and Kindle. Book excerpt: Theoretical and empirical accounts of the interconnectedness between the manual and the mental suggest that the hand can be understood as a cognitive instrument. Cartesian-inspired dualism enforces a theoretical distinction between the motor and the cognitive and locates the mental exclusively in the head. This collection, focusing on the hand, challenges this dichotomy, offering theoretical and empirical perspectives on the interconnectedness and interdependence of the manual and mental. The contributors explore the possibility that the hand, far from being the merely mechanical executor of preconceived mental plans, possesses its own know-how, enabling "enhanded" beings to navigate the natural, social, and cultural world without engaging propositional thought, consciousness, and deliberation. The contributors consider not only broad philosophical questions—ranging from the nature of embodiment, enaction, and the extended mind to the phenomenology of agency—but also such specific issues as touching, grasping, gesturing, sociality, and simulation. They show that the capacities of the hand include perception (on its own and in association with other modalities), action, (extended) cognition, social interaction, and communication. Taken together, their accounts offer a handbook of cutting-edge research exploring the ways that the manual shapes and reshapes the mental and creates conditions for embodied agents to act in the world.

Book Synopsis Handedness and Brain Asymmetry by : Marian Annett

Download or read book Handedness and Brain Asymmetry written by Marian Annett. This book was released on 2013-04-15. Available in PDF, EPUB and Kindle. Book excerpt: 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.
