The book presents new and stimulating approaches to the study of language evolution and considers their implications for future research. Leading scholars from linguistics, primatology, anthroplogy, and cognitive science consider how language evolution can be understood by means of inference from the study of linked or analogous phenomena in language, animal behaviour, genetics, neurology, culture, and biology. In their introduction the editors show how these approaches can be interrelated and deployed together through their use of comparable forms of inference and the similar conditions they place on the use of evidence. The Evolutionary Emergence of Language will interest everyone concerned with this intriguing and important subject, including those in linguistics, biology, anthropology, archaeology, neurology, and cognitive science.

The past decade has brought extraordinary gains in the outlook for children stricken with cancer. Though cancer remains a leading cause of death for children and young adults, more victims of child hood cancer today will survive than will die. The therapeutic advances and the optimism they instill have prompted researchers and clinicians to analyze the impact of cancer upon young patients and their famil, ies and to devise more effective intervention strategies. Hope and survival, juxtaposed with the continuing high mortality associated with certain forms of the illness, add new challenges to management of the psychosocial aspects of cancer. To respond to these challenges we need research as rigorous as that which continues to make inroads in treating the physical illness. This specific concern for the needs of children suffering from cancer and their families has paralleled an increasing sensitivity on the part of the medical community and the public at large to the limitations of specialized, high technology health care practices."

Shaping Primate Evolution is an edited collection of papers about how biological form is described in primate biology, and the consequences of form for function and behavior. The contributors are highly regarded internationally recognized scholars in the field of quantitative primate evolutionary morphology. Each chapter elaborates upon the analysis of the form-function-behavior triad in a unique and compelling way. This book is distinctive not only in the diversity of the topics discussed, but also in the range of levels of biological organization that are addressed from cellular morphometrics to the evolution of primate ecology. The book is dedicated to Charles E. Oxnard, whose influential pioneering work on innovative metric and analytic techniques has gone hand-in-hand with meticulous comparative functional analyses of primate anatomy. Through the marriage of theory with analytical applications, this volume will be an important reference work for all those interested in primate functional morphology.

An extensively revised third edition of this introduction to neuroethology - the neuronal basis of animal behaviour - for zoology, biology and psychology undergraduate students. The book focuses on the roles of individual nerve cells in behaviour, from simple startle responses to complex behaviours such as route learning by rats and singing by crickets and birds. It begins by examining the relationship between brains and behaviour, and showing how study of specialised behaviours reveals neuronal mechanisms that control behaviour. Information processing by nerve cells is introduced using specific examples, and the establishing roles of neurons in behaviour is described for a predator-prey interaction, toads versus cockroaches. New material includes: vision by insects, which describes sensory filtering; hunting by owls and bats, which describes sensory maps; and rhythmical movements including swimming and flying, which describes how sequences of movements are generated. Includes stunning photographs which capture the detail of the behaviour.

Grooming is among the most evolutionary ancient and highly represented behaviours in many animal species. It represents a significant proportion of an animal's total activity and between 30-50% of their waking hours. Recent research has demonstrated that grooming is regulated by specific brain circuits and is sensitive to stress, as well as to pharmacologic compounds and genetic manipulation, making it ideal for modelling affective disorders that arise as a function of stressful environments, such as stress and post-traumatic stress disorder. Over a series of 12 chapters that introduce and explicate the field of grooming research and its significance for the human and animal brain, this book covers the breadth of grooming animal models while simultaneously providing sufficient depth in introducing the concepts and translational approaches to grooming research. Written primarily for graduates and researchers within the neuroscientific community.

Indonesia possesses the second largest primate population in the world, with over 33 different primate species. Although Brazil possesses more primate species, Indonesia outranks it in terms of its diversity of primates, ranging from prosimians (slow lorises and tarsiers), to a multitude of Old World Monkey species (macaques, langurs, proboscis moneys) to lesser apes (siamangs, gibbons) and great apes (orangutans). The primates of Indonesia are distributed throughout the archipelago. Partly in response to the number of primates distributed throughout the Indonesian archipelago, Indonesia is classified as the home of two biodiversity hotspots (Wallacea and Sundaland). In order to be classified as a hotspot, an area must have a large proportion of endemic species coupled with a high degree of threat including having lost more than 70% of its original habitat. Two areas within Indonesia meet these criteria. The tremendous diversity of primates in Indonesia, in conjunction with the conservation issues facing the primates of this region, created a need for this volume.

This book traces the evolution of the dog, from its origins about 15,000 years ago up to recent times. The timing of dog domestication receives attention, with comparisons between different genetics-based models and archaeological evidence. Allometric patterns between dogs and their ancestors, wolves, shed light on the nature of the morphological changes that dogs underwent. Dog burials highlight a unifying theme of the whole book: the development of a distinctive social bond between dogs and people; the book also explores why dogs and people relate so well to each other. Though cosmopolitan in overall scope, the greatest emphasis is on the New World, with an entire chapter devoted to dogs of the arctic regions, mostly in the New World. Discussion of several distinctive modern roles of dogs underscores the social bond between dogs and people.

This is the first in a series of volumes concerned with research encompassed by the rather broad term "environment and behavior. " The goal of the series is to begin the process of integration of knowledge on environmental and behavioral topics so that researchers and professionals can have material from diverse sources accessible in a single publication. The field of environment and behavior is broad and interdiscipli nary, with researchers drawn from a variety of traditional disciplines such as psychology, sociology, anthropology, geography, and other social and behavioral sciences, and from the biological and life sciences of medicine, psychiatry, biology, and ethology. The interdis ciplinary quality of the field is also reflected in the extensive involve ment of environmental professionals from architecture, urban plan ning, landscape architecture, interior design, and other fields such as recreation and natural resources, to name just a few. At present, the field has a somewhat chaotic flavor, with research being carried out by a variety of scholars who publish in a multitude of outlets. Many researchers and practitioners are unaware of the state of knowledge regarding a specific topic because of the unavailability of integrated reference materials. There are only a handful of books dealing with environment and behavior, most of them unintegrated collections of readings, with only an occasional systematic analysis of some facet of the field."

Anxiety is one of those entltles which everyone "knows," but which ultimately resists simple objective description. The essence of the phenomenon is its subjectivity. True it has its well documented associated physiological events: the increased pulse rate and blood pressure, sweating, and so on, but each of these phenomena may also be part of physical exertion, fear, or even pleasurable excitement. They cannot fully define the sense of threat, danger, collapse, malignancy in greater or smaller amount, in greater or lesser locali sation, with more or less objective evidence for its validity that characterises the particular psychological pain we all recognize as anxiety. It is precisely the essential subjectivity of anxiety and its association with an enormous range of experience that makes it difficult to assign to it well-defined diagnostic labels of the kinds so carefully described by Dr. Spitzer in his chapter on classification. His chapter ranges from the extreme dread of "Panic Disorders," to the diffuse terror of the environment which used to be labelled "Agoraphobia" (and is still so called in the day to day pragmatic usage of many clinics) and is not assimilated to the class of phobias with the label "Social Phobias." He also addresses the "Simple Phobias" which are perhaps the most readily labelled of the many varieties of anxiety."

It is an intriguing feature of human experience that in our present world, amid thousands of indications of the effectiveness of the scientific method, so many of us persist in demonstrably illusory or magical beliefs whether religiously related or simply reflections of long-standing superstitions. At a time when millions can observe on television the first landings of human beings on the moon, when our daily lives in the so-called devel oped countries are replete with conveniences that reflect scientific advances, we still persist in daily wagers on the state lotteries, in paying astrologers or palmists for their readings, in investing thousands of dollars and hours of our legislators' time in discussing such issues as the value of daily prayer in the elementary schools. The emergence of modem medicine based increasingly on scientific research in chemistry, biology, and physics has considerably reduced people's resort to sha mans and witch doctors within the major sectors of our own society, although it has by no means eliminated such practitioners."

It has been estimated that there are at least 2,500,000 adults, 10% of the population above age 65, who are currently in need of some sort of mental health services (Kramer, Taube, and Redick, 1973). Other estimates are even higher (e. g., Pfeiffer, 1977). It is expected that this number will increase as the number of older adults increases over the next 40 years. Probably less than 400 clinical psychologists are now provid ing services to this age group. The number of elderly patients actually seen by these psychologists is very, very small. One national survey found that of 353 psychologists who reported that they had older clients, only 495 individuals were seen for psycho logical testing and 1423 for psychotherapy in the one month just prior to the response (Dye, in press). Assuming that the same in dividuals were not seen for both testing and therapy within the one month period--a questionable assumption--approximately . 08% of the at least two-and-one-half million older adults in need of psychological services are now being supplied with these services in some form or another. Thus, the need for increased involvement of clinical psychology with the aged is undeniable. However, few resources currently exist which will serve to increase the number of clinical psychologists trained to meet this need. Probably less than 100 clinical psychologists living today have received any kind of formal graduate training in the clinical psychology of the aging (Storandt, 1977)."

From the President of the Research Society on Alcoholism The field of alcohol research has been slowly but continuously evolving, taking into its domain an ever-increasing array of scientific disciplines. This senes is designed to fill the need for, a review publication that covers the broad range of research into alcohol actions and alcoholism. Research in alcohol concerns social, epidemiological, and legal concerns in addition to biomedical and behavioral topics to greater degree than research with many other drugs. A publication devoted to alcohol research should serve the broadest existing research community, but perhaps more important, it should also provide a means to recruit new investigators with fresh approaches to the field. We can and must demonstrate that legitimate, high-quality research is being done, but we must also highlight the opportunity for new workers to make a real impact on the problem. The Research Society on Alcoholism seeks to provide such a service not only through this publication but also through other ac tivities. Richard A. Deitrich, Ph.D."

Psychotherapy research is undoubtedly one of the most puzzling, diverse, com plex, controversial, and multidimensional areas tackled by clinical psycholo gists, psychiatrists, and psychiatric social workers. The numerous theoretical, methodological, and clinical-research issues dealt with by workers in the field have increased exponentially in the past three decades. To do full justice to the area, monographs in each of the specific subareas would be warranted. In this volume, we, as editors, have endeavored to present the student and interested professional and practitioner with an understanding of the most salient issues and trends confronted by the psychotherapy researcher. In order to accomplish this task, we asked our colleagues, who are experts in their respective areas, to share their current thinking with us and with you, the read ers. Thus, many theoretical viewpoints are represented, with none having a monopoly over the others. This is as it should be, given the data collected by clinical researchers at this time. We have also attempted to capture the excite ment that has permeated the field in the past 30 years or so."

Although a number of books have appeared on learning disabili ties, we feel that the present book has two distinct features which are not found in most others. It is multidisciplinary and it com bines theory with practice. A group of researchers from the disciplines of Psychology in cluding medical psychology and information processing, Reading, Special Education and Physical Education interacted with each other before and after their presentations in a conference (November 1980, at the University of Alberta, Edmonton, Canada), and then wrote their chapters for this book. We hope that their chapters were enriched by the discussions and arguments which happened in formal and informal settings during the authors' stay in Edmonton. Dr. Leong could not attend the conference, but was asked to write the introductory chapter for the book. The contributors to this volume have been involved with basic research as well as with clinical and educational research in learning disabilities. Some of them have a theoretical rather than a practical interest. However, a serious interest in a handicapping condition perhaps compels one to consider its amelioration no matter how 'pure' is the researcher. It is because of such a feeling.that those who do basic research have sug gested procedures for applying their findings. The result is a balanced product, entailing theory and practice."

"Seek simplicity and distrust it. " Alfred North Whitehead "It will become all too clear that an ability to see patterns in behavior, an ability that some might feel proud of, can lead more easily to a wrong description than a right one. " William T. Powers The goal of the theorist-the scholar-is to take a collection of observations of the world, and perceive order in them. This process necessarily imposes an artificial simplicity upon those observations. That is, specific observations are weighed differently from each other whenever a theoretical account is abstracted from raw experiences. Some observed events are misunderstood or distorted, others are seen as representing random fluctuations and are ignored, and yet others are viewed as centrally important. This abstraction and oversimplification of reality is inevitable in theory construction. Moreover, the abstracted vision builds upon itself. That is, as a structure begins to emerge from continued observation, the structure itself guides the search for new information. The result is a construction that is more elaborate than what existed before, but it still is usually simpler than reality. It is important for scholars to believe in the value of their task, and in the general correctness of the vision that guides their work. This commitment, and the hope of progress that follows from it, make it possible to continue even when the work is difficult and slow.

"It is not thought as such that can move anything, but thought which is for the sake of something and is practical." This discerning insight, which dates back more than 2000years to Aristotle, seems to have been ignored by most psycholo gists. For more than 40years theories of human action have assumed that cogni tion and action are merely two sides of the same coin. Approaches as different as S-O-R behaviorism, social learning theory, consistency theories, and expectancy value theories of motivation and decision making have one thing in common: they all assume that "thought (or any other type of cognition) can move any thing," that there is a direct path from cognition to behavior. In recent years, we have become more and more aware of the complexities in volved in the relationship between cognition and behavior. People do not always do what they intend to do. Aside from several nonpsychological factors capable of reducing cognition-behavior consistency, there seems to be a set of complex psychological mechanisms which intervene between action-related cognitions, such as beliefs, expectancies, values, and intentions, and the enactment of the be havior suggested by those cognitions. In our recent research we have focused on volitional mechanismus which presumably enhance cognition-behavior consistency by supporting the main tenance of activated intentions and prevent them from being pushed aside by competing action tendencies."

In the past fifteen years there has been considerable interest in neural circuits that initiate behavior patterns. For many types of behaviors, this involves decision-making circuits whose primary elements are neither purely sensory nor motor, but represent a higher order of neural pro cessing. Of the large number of studies on such systems, analyses of startle circuits compose a major portion, and have been carried out on systems found throughout the animal kingdom. Startle has been an im portant model because of the reliability of the behavioral act for laboratory study and the accessibility of the underlying neural circuitry. However, probably because of the breadth of the subject, this material has never been reviewed in a comprehensive way that presents the elements com mon to startle circuits in the different animal systems in which they occur. This book presents a diversity of approaches based on a broad back ground of animal groups ranging from the earliest nervous systems in cnidarians to the most recently evolved and advanced in mammals. The behaviors themselves are all short latency, fast motor acts, when consid ered on the time scale of the organism, and involve avoidance or evasion, although in some cases we do not yet completely understand their natural role. These behaviors occur in response to stimuli that have sudden or unexpected onset."

Animal behaviour, as a discipline, has undergone several key transitions over the last 25 years, growing in both depth and breadth. Key advances have been made in behavioural ecology and socio-biology, in the development of studies integrating proximate and ultimate causation, in the integration of laboratory and field work, and in advances in theoretical work in areas such as sexual selection, foraging and life-history traits. Thus it is appropriate to relate the individual stories of those who have had significant impacts on the field as we know it today. Leaders in Animal Behaviour: The Second Generation is a collection of autobiographies from 21 individuals that have been peer selected, and have provided unique and important contributions to the field in the past 25 years.

In the eight years since the publication of the second edition of this Guide, psycho phannacotherapy has made many advances not only through the discovery of new medications but by the effective directing of their use to an ever-increasing variety of clinical disorders. These welcome developments are reflected in the concurrent growth and development of the Guide itself, which now enters adulthood with renewed vigor. Under the thoughtful and scholarly leadership of Dr. Alan Gelenberg, the third edition has undergone a significant transformation designed to meet the needs of the modem clinician. The panel of contributors is nearly double that of the former edition with the addition of nine new authors, who have helped in the major revision and rewriting of the text and in a broadening of the topics included. As a conse quence, the reader is assured of a thorough and thoroughly up-to-date coverage of current psychopharmacology that is both accurate and aimed at clinical utility. Having reached maturity, the third edition, while maintaining the lineaments of its earlier versions, is a considerably expanded and strengthened guide to treatment. Although now more encyclopedic in content, the new Practitioner' s Guide to Psy choactive Drugs retains the virtues of a clinical vade mecum that informed its predecessors and have eamed it a place by the patient's bedside for weIl over a decade. One may confidently anticipate its long and flourishing career in the years ahead. John C. Nemiah, M.D."

Predation is an ecological factor of almost universal importance for the biol ogist who aims at an understanding of the habits and structures of animals. Despite its pervasive nature opinions differ as to what predation really is. So far it has been defined only in negative terms; it is thought not to be par asitism, the other great process by which one organism harms another, nor filter-feeding, carrion-eating, or browsing. Accordingly, one could define predation as a process by which an animal spends some effort to locate a live prey and, in addition, spends another effort to mutilate or kill it. Ac cording to this usage of the word a nudibranch, for example, that feeds on hydroids would be a predator inasmuch as it needs some time to locate col onies of its prey which, after being located, scarcely demand more than eating, which differs little from browsing. From the definition just proposed consumption of the prey following its capture has been intentionally omit ted. Indeed, an animal may be disposed of without being eaten. Hence the biological significance of predation may be more than to maintain nutrition al homeostasis. In fact, predation may have something in common with the more direct forms of competition, a facet that will be only cursorily touched upon in this book."

The papers comprising this second volume of Human Behavior and the Environment represent, as do their predecessors, a cross section of current work in the broad area of problems dealing with interrelation ships between the physical environment and human behavior, at both the individual and the aggregate levels. Considering the two volumes as a unit, we have included papers covering a broad spectrum of problems ranging from the theoretical to the applied, and from the disciplinary-based to the interdisciplinary and professional. Approxi mately half of the papers are written by psychologists, with the remainder coming, in part, from such other disciplines as sociology, geography, and from such diverse applied and professional fields as natural recreation, landscape architecture, urban planning, and opera tions research. The volumes thus provide an overview of work on current topical problems. Yet, as the field is developing, specialization is inevitably increasing apace, and the editors as well as the publisher have become convinced of the desirability for futu're volumes in this series to be organized along topical lines, with successive volumes devoted to different aspects of this rather sprawling field. Thus, Volume 3, currently in the planning stage, will be devoted exclusively to the interaction of children with the physical environment, considered from diverse viewpoints, again including authors from diverse fields of specialization."

This fifth edition arms readers with the latest information on nutrient metabolism and the formulation of diets from an array of available feedstuffs. The authors discuss animals' role in ecological balance, environmental stability and sustainable agriculture and food production. A new chapter on the regulation of nutrient partitioning offers a lively and timely discussion of emerging technologies in modifying and increasing efficiency of nutrient metabolism and animal food composition. A new chapter on toxic minerals in the food chain addresses the role of agricultural production animal nutrition in protecting the environment from toxic levels of minerals and nitrogen in the food chain.

The small but growing body of information about auditory processes in infancy is a tribute to the ingenuity and persistence of investigators in this realm. Undeter red by the frequent expressions of boredom, rage, and indifference in their subjects, these investigators nevertheless continue to seek answers to the intrigu ing but difficult questions about the course of auditory development. In the spring of 1981, a group of leading scholars and researchers in audi tion gathered to discuss the topic, Auditory Development in Infancy, at the 11th annual psychology symposium at Erindale College, University of Toronto. They came from both sides of the Atlantic and from various disciplines, including audiology, neurology, physics, and psychology. They shared their views on theory and data, as well as their perspectives from the laboratory and clinic. One unexpected bonus was an unusually distinguished audience of researchers and clinicians who contributed to lively discussion within and beyond the formal sessions."

On being asked to write a book on migration and homing in animals, intended as an introductory text to inform and stimulate both students and non-specialists, I saw the following alternatives for an outline: (1) I could discuss known or hypothetical mechanisms of orientation, and enumerate animals known or thought to use these mechanisms in migration and homing. (2) I could discuss the known feats of orientation by animals under field observation (e. g. migration), following some practic able order, with a subsequent discussion of the attempts at and possible success in elucidating the basic mechanisms of orientation. Both alternatives have obvious disadvantages. (1) would suffer from the fact (a) that very few orientation mechanisms (such as the sun, star, or magnetic compass) have been firmly established and (b) that for many animals the modes of orienta tion are unknown; therefore, for many animals whose consider able feats of orientation are well known, an appropriate alloca tion could not be made. With (2) the disadvantage is that due to the complexity of animal movements, it is difficult to find some relevant order and that in many animal groups discussions of certain known mechanisms such as the sun com pass would recur. I have selected outline (2) as the much lesser evil. The discussion pursues a compromise between taxonomic order and similarity in feats of orientation or methodological approaches chosen by the various investigators."
