Chickens are by far the world’s most widely farmed animal, kept for both meat and egg production. They are at the centre of many debates regarding housing and production systems, causing significant interest in what lies behind chicken behaviour. This accessible book covers sensory biology, behavioural development, preferences and aversions, social behaviour, learning and cognition, behavioural issues in different systems and solutions for behavioural problems. Authored by an authority on chicken ethology, it brings together the fields of animal behaviour, neuroscience, psychology and epidemiology to provide a comprehensive understanding of chicken behaviour and help improve the lives of farmed chickens around the world.

Asymmetry of the brain and behaviour (lateralization) has traditionally been considered unique to humans. However, research has shown that this phenomenon is widespread throughout the vertebrate kingdom and found even in some invertebrate species. A similar basic plan of organisation exists across vertebrates. Summarising the evidence and highlighting research from the last twenty years, the authors discuss lateralization from four perspectives - function, evolution, development and causation - covering a wide range of animals, including humans. The evolution of lateralization is traced from our earliest ancestors, through fish and reptiles to birds and mammals. The benefits of having a divided brain are discussed, as well as the influence of experience on its development. A final chapter discusses outstanding problems and areas for further investigation. Experts in this field, the authors present the latest scientific knowledge clearly and engagingly, making this a valuable tool for anyone interested in the biology and behaviour of brain asymmetries.

The aim of Advances in the Study of Behavior remains as it has been since the series began: to serve the increasing number of scientists who are engaged in the study of animal behavior by presenting their theoretical ideas and research to their colleagues and to those in neighboring fields. We hope that the series will continue its "contribution to the development of the field", as its intended role was phrased in the Preface to the first volume in 1965. Since that time, traditional areas of animal behavior have achieved new vigor by the links they have formed with related fields and by the closer relationship that now exists between those studying animal and human subjects.Advances in the Study of Behavior, Volume 31 continues to serve scientists across a wide spectrum of disciplines. Focusing on new theories and research developments with respect to behavioral ecology, evolutionary biology, and comparative psychology, these volumes foster cooperation and communications in these dense fields.

No longer viewed as a characteristic unique to humans, brain lateralization is considered a key property of most, if not all, vertebrates. This field of study provides a firm basis from which to examine a number of important issues in the study of brain and behaviour. This book takes a comparative and integrative approach to lateralization in a wide range of vertebrate species, including humans. It highlights model systems that have proved invaluable in elucidating the function, causes, development, and evolution of lateralization. The book is arranged in four parts, beginning with the evolution of lateralization, moving to its development, to its cognitive dimensions, and finally to its role in memory. Experts in lateralization in lower vertebrates, birds, non-primate mammals, and primates have contributed chapters in which they discuss their own research and consider its implications to humans. The book is suitable for researchers, graduates and advanced undergraduates in psychology, neuroscience and the behavioral sciences.

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".

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.

`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.

An understanding of social behaviour is increasingly necessary in farm animal husbandry as more animals are housed in groups rather than in individual stalls or pens. There may be economic or welfare reasons for such housing. This book is the first to specifically address this important subject. The chapters fall into three broad subject areas: concepts in social behaviour; species specific chapters; current issues. Authors include leading experts from Europe, North America, Australia and New Zealand.Animal welfare/behaviour issues are becoming increasingly importantCombines theoretical and practical details about the social behaviour of our most common farm speciesWritten by leading experts from around the world
