Hemispheric specialization, and lateralized sensory, cognitive or motor function of the left and right halves of the brain, commonly manifests in humans as right-handedness and left hemisphere specialization of language functions. Historically, this has been considered a hallmark of, and unique to, human evolution. Some theories propose that human right-handedness evolved in the context of language and speech while others that it was a product of the increasing motor demands associated with feeding or tool-use. In the past 20-25 years, there has been a plethora of research in animals on the topic of whether population-level asymmetries in behavioral processes or neuro-anatomical structures exist in animals, notably primates and people have begun to question the historical assumptions that hemispheric specialization is unique to humans. This book brings together various summary chapters on the expression of behavioral and neuro-anatomical asymmetries in primates. Several chapters summarize entire families of primates while others focus on genetic and non-genetic models of handedness in humans and how they can be tested in non-human primates. In addition, it makes explicit links between various theoretical models of the development of handedness in humans with the observed patterns of results in non-human primates. A second emphasis is on comparative studies of handedness in primates. There is now enough data in the literature across different species to present an evolutionary tree for the emergence of handedness (and perhaps other aspects of hemispheric specialization, such as neuro-anatomical asymmetries) and its relation to specific morphological and ecological adaptations in various primate species.* The first treatment of this important topic since 1998* Examines the tenet that lateralization and handedness is a uniquely human character through evidence from higer and lower primates and with reference to other vertebrates.* Advances our understanding of the occurrence, evolution and significance of lateralization and handedness effects.

Understanding the chimpanzee mind is akin to opening a window onto human consciousness. Many of our complex cognitive processes have origins that can be seen in the way that chimpanzees think, learn, and behave. The Mind of the Chimpanzee brings together scores of prominent scientists from around the world to share the most recent research into what goes on inside the mind of our closest living relative. Intertwining a range of topics—including imitation, tool use, face recognition, culture, cooperation, and reconciliation—with critical commentaries on conservation and welfare, the collection aims to understand how chimpanzees learn, think, and feel, so that researchers can not only gain insight into the origins of human cognition, but also crystallize collective efforts to protect wild chimpanzee populations and ensure appropriate care in captive settings. With a breadth of material on cognition and culture from the lab and the field, The Mind of the Chimpanzee is a first-rate synthesis of contemporary studies of these fascinating mammals that will appeal to all those interested in animal minds and what we can learn from them.

Neurobiology of Social Communication in Primates: An Evolutionary Perspective presents evidence on the neural basis of communicative behavior in primates, reevaluating the relationship between human language and animal communication in view of the linguistic abilities of chimpanzees. This book consists of 10 chapters. Chapter 1 discusses some of the persistent problems in evolutionary neurobiology of primate communication. The effects of brain lesions and stimulation on vocalization in New and Old World monkeys, relation between species differences in peripheral vocal structures and species contrasts in vocal performance, and anatomy and physiology of the nonhuman primate auditory system are reviewed in Chapters 2 to 4. Chapters 5 to 7 examine the effects of electrical brain stimulation on human verbal communication and facial expression, clinical data pertaining to language pathologies, and neural mechanisms of manual and oral control. The last three chapters summarize the materials presented in earlier chapters. This publication is recommended for neuroscientists, behavioral biologists, neurologists, psychiatrists, and students interested in the evolutionary heritage of human speech and language.

This book arrays recent research on the neural and behavioral lateralization of the brain relying heavily on animal modes. The authors employ the comparative method to enhance our understanding of behavior, specifically through hand use and "handedness" by drawing comparisons with studies involving primates. Topics discussed include Patterns of Lateralized Behavior in Prosimians; Behavioral Lateralization in Language-Trained Chimpanzees; Patterns of Handedness: Comparative Study of Nursery School Children and Captive Gorillas; and Rotational Behavior in Children and Adults. It is the first book of its kind devoted entirely to the question of behavioral asymmetries in all primates and thus presents a milestone as it recognizes the accumulating evidence of asymmetry and lateralized behavior in the non-human nervous system.

This edited volume is the first of its kind to bridge the epistemological gap between primate ethologists and primate neurobiologists. Leading experts in several fields review work ranging from primate foraging behavior to the neurophysiology of motor control, from vocal communication to the functions of the auditory cortex.

This volume originates from a NATO Advanced Research Workshop held in Maratea. Italy from 8th-15th October 198~. Aims and contributions are described at greater length in the Introduction and the following chapters. It is hoped that this volume will provide a critical overview of hemispheric specialization in relation to individual differences, but one that is not intended to be comprehensive. Three contributions on this theme are made by authors who were invited to the Workshop but were unable to participate in it. The volume contains a critical appraisal of the differentially specialized functions of left and right human cerebral hemispheres in verbal and visuospatial domains respectively (formerly cerebral dominance). in relation to individual variation due. for example. to gender and handedness. Critical cross-comparison of several methods of assessing hemispheric specialization such as perceptual/behavioral. clinical/neurological. electrophysiological and "real time" methods of assessment of cerebral orientation have been made. Individual differences have been considered in relation to statistical concepts in the assessment of cerebral lateralization. Some emphasis has been placed on the application of these methods and concepts to psychopathology.

This book presents a current, interdisciplinary perspective on language requisites from both a biological/comparative perspective and from a developmental/learning perspective. Perspectives regarding language and language acquisition are advanced by scientists of various backgrounds -- speech, hearing, developmental psychology, comparative psychology, and language intervention. This unique volume searches for a rational interface between findings and perspectives generated by language studies with humans and with chimpanzees. Intended to render a reconsideration as to the essence of language and the requisites to its acquisition, it also provides readers with perspectives defined by various revisionists who hold that language might be other than the consequence of a mutation unique to humans and might, fundamentally, not be limited to speech.

The third book in Young’s unique trilogy on causality and development continues to locate and define the central role of causality in biopsychosocial and network/systems development, and as a unifying concept of psychology itself. As a way of discussing causality, in general, initially, the book focuses on the acquisition of handedness and hemispheric specialization in infancy and childhood, and their relations to the development of cognition, language, and emotion, in particular. The second part of the book elaborates an innovative 25-step Neo-Eriksonian model of development across the life course based on a Neo-Piagetian model covered in the previous books, completing a step-by-step account of development over the lifespan cognitively and socio-emotionally. It builds on the concept of neo-stage, which is network-based. From this conceptual synthesis, the author’s robust theory of development and causality identifies potential areas for psychological problems and pathology at each developmental step as well as science-based possibilities for their treatment. This elegant volume: Presents a clear picture of the development of handedness and laterality in more depth than has been attempted in the literature to date. Traces the causal concepts of activation-inhibition coordination and networking in the context of development. Describes in depth a novel 25-step Neo-Eriksonian lifespan model of development. Reviews relevant research on Piagetian and Eriksonian theories in development. Emphasizes the clinical utility of the described 25-step Neo-Eriksonian approach to lifespan development. A significant step in understanding this highly nuanced subject and synthesizing a broad knowledge base, Causality and Development will find an interested audience among developmental psychologists, mental health practitioners, academics, and researchers.chers.
