This volume was generated from papers presented at the Second Triennial Symposium of the International Basal Ganglia Society (IBAGS) held at the University of Victoria, British Columbia, July 21-23, 1986. The meeting was held as a satellite symposium following the XXX Congress of the International Union of Physiological Sciences at Vancouver. IBAGS was founded at a similar satellite symposium held in Lorne, Australia, organized by John S. McKenzie and sponsored by the University of Melbourne. The symposium held in Australia was attended by 50 scientists from 12 different countries. The results of the first symposium, edited by John S. McKenzie, Robert E. Kemm and Lynette N. Wilcock, were published by Plenum Press in 1984 under the title, The Basal Ganglia - Structure and Function. It was decided that the Society should meet on a triennial basis. The time and place for Second IBAGS Symposium were set by A.G. Phillips who served as Chairman of the Program Committee along with I. Divac, S.A. Greenfield and E.T. Rolls and J.S. McKenzie. Michael E. Corcoran of the Department of Psychology, University of Victoria served as the on-site coordinator and arranger for the Symposium. He was ably assisted by Ms. Morag McNeil who handled the details which made the meeting run smoothly.

"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."

Overview of current trends in the psychology of motivation and volition, covering basic research as well as developmen- tal and applied aspects. Intention and volition are consi- dered in chapters on behavior dynamics, self-regulation, and control over intention and actions.

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."

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."

"Continuities and Discontinuities in Development" was the theme for the Second Biennial DPRG Retreat, a three-day meeting held at Estes Park, Colorado, in June 1982. The meeting was sponsored by the Devel opmental Psychobiology Research Group (DPRG) of the Department of Psychiatry at the University of Colorado School of Medicine. The DPRG is a group of individuals conducting research in many areas of develop ment who meet on a regular basis to present and discuss their work and receive feedback and encouragement. In 1974, this group was awarded an endowment fund by the Grant Foundation, the aims of which were to facilitate the research of young investigators, to encourage new re search, and to provide seed money for collaborative ventures. Much of the work reported in this volume and in the earlier volume from the First DPRG Retreat is the result of that support. In addition to the work of the members of the DPRG, a select group of guests was invited to participate in the meeting and contribute to this volume. The chapters by William Greenough, Jerome Kagan, and Michael Rutter result from the participation of these scholars at the retreat. We would like to acknowledge the support of a number of indi viduals who have been instrumental in supporting the DPRG as a whole, as well as those who contributed directly to the Second Biennial Retreat and to the volume."

Offers the first comprehensive resource to document the particular needs of a given species in captivity. Each species is dealt with by specialists who are fully familiar with their animals, writing to a consistent template to facilitate easy navigation. Each chapter in Part 2 addresses specific species-typical behaviours associated with pain and distress. The third section contains a series of easy reference ethograms that will aid understanding, and potentially quantification of i.e., baboon, bird, or bovine behavior. The book will be useful not only in laboratory settings, but any situation where an animal is kept in captivity, from veterinary clinics to zoos and sanctuaries. Edited by internationally recognized experts in animal behaviour and behavioural management.

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."

As I begin to write this Preface, I feel a rush of excitement. I have now finished the book; my gestalt is coming into completion. Throughout the months that I have been writing this, I have, indeed, been intrinsically motivated. Now that it is finished I feel quite competent and self-determining (see Chapter 2). Whether or not those who read the book will perceive me that way is also a concern of mine (an extrinsic one), but it is a wholly separate issue from the intrinsic rewards I have been experiencing. This book presents a theoretical perspective. It reviews an enormous amount of research which establishes unequivocally that intrinsic motivation exists. Also considered herein are various approaches to the conceptualizing of intrinsic motivation. The book concentrates on the approach which has developed out of the work of Robert White (1959), namely, that intrinsically motivated behaviors are ones which a person engages in so that he may feel competent and self-determining in relation to his environment. The book then considers the development of intrinsic motiva tion, how behaviors are motivated intrinsically, how they relate to and how intrinsic motivation is extrinsically motivated behaviors, affected by extrinsic rewards and controls. It also considers how changes in intrinsic motivation relate to changes in attitudes, how people attribute motivation to each other, how the attribution process is motivated, and how the process of perceiving motivation (and other internal states) in oneself relates to perceiving them in others."

The abuse of alcohol presents a major health problem throughout the world. Until recently both clinical and research efforts have been geared toward treatment and rehabilitation of alcoholism. With the growing num ber of problem drinkers entering treatment, the need for a better under standing of the prevention of alcohol abuse has become increasingly evi dent. Although still in its infancy, the field of alcoholism prevention is growing at a rapid rate. Increasing numbers of behavioral scientists through out the world are conducting or planning prevention projects. Policy plan ners, school administrators, military agencies, community groups, state and local alcoholism agencies, and industries are initiating alcohol abuse preven tion programs with fervor. Legislators at all levels of government are also developing a keen interest in legislation aimed at reducing the extent of problem drinking. This book represents one of the first systematic attempts to compile a comprehensive text on the prevention of alcohol abuse. Many of the con tributors to Prevention 0/ Alcohol Abuse have international reputations that strengthen their understanding of the complex nature of prevention. By providing a critical review of the current knowledge about prevention, the text will serve to stimulate and lay the groundwork for further prevention efforts. We thank all of the chapter authors for their excellent contributions. It is through their efforts that the field will thrive. Our appreciation also is expressed to Leonard Pace, formerly of Plenum Press, for his encourage ment and helpful comments in the development of the text."

In addition to filling a need within the field of parental behavior, this book contributes importantly to the growing area of emotional and motivational neuroscience. A major part of neuroscience research at the whole organism level has been focused on cognitive neuroscience, with an emphasis on the neurobiology of learning and memory, but there has been a recent upsurge in research which is attempting to define the neural basis of basic motivational and emotional systems which regulate such behaviors as food intake, aggression, reproduction, reward-seeking behaviors, and anxiety-related behaviors. In this book the emphasis is on the research findings obtained from rodents, sheep and primates. The authors' goal, of course, was to provide a foundation that may help us understand the neurobiology of human parental behavior. Indeed, the last chapter attempts to integrate the non-human research data with some human data in order to make some inroads toward an understanding of postpartum depression, child abuse, and child neglect. Clearly, motivational and emotional neuroscience has close ties to psychiatry, and this connection will be very evident in the final chapter. By understanding the neurobiology of parental behavior we are also delving into neurobiological factors which may have an impact on core human characteristics involved in sociality, social attachment, nurturing behavior, and love. In this very violent world, it is hard to conceive of a group of characteristics that are more worthy of study.

The topic of animal motivation deals with how and why animals engage in particular activities: what mechanisms inside the animal generate behaviour, how stimuli from the external environment in fluence these mechanisms, and how this behaviour is beneficial to the animal. The topic is thus central both to academic studies in psychology and zoology and to applied matters in domestic species. Motivation has not been an area of great emphasis in the past 10-15 years but there is now a growing realization that it should receive greater attention. Drawing on concepts and observations from a number of areas, this book provides an overview of the motiva tional processes which determine the choices, timing, and sequencing which are characteristic of animal behaviour. Data and theory from ethology, psychology, and evolutionary biology are synthesized into a contemporary framework for analysing such central features of behaviour as persistence in activities and goal orientation. Principles of motivational analysis are discussed and illustrated with specific case studies. The successive chapters deal with ethological, phy siological, and ecological approaches involving experimental work on a diversity of vertebrate and invertebrate species. Ethological topics include the interaction of external stimuli and internal states, mechanisms of choice, quantitative models of motivation, conflict between tendencies for different activities, and behavioural homeos tasis. The review of physiological research focuses on hunger, the activating roles of nerves and hormones, and the examination of animals with small nervous systems."

Over the last several decades, the remarkable success of science and medical technology has allowed many children with chronic illness and handicapping conditions to live longer and healthier lives. But this suc cess is not without toll. The human cost of chronic illness or a handicap ping condition can be enormous for the child and the family. For the family, there is often the stressful daily burden of care, fatigue, marital stress, low family morale, financial burdens, and reduced career mobili ty. For the child, there are often arduous and painful treatment regimes, frequent school absences, low energy periods, and uncertainties with respect to future education and vocation. The course of many diseases is unpredictable, and the very fact of chronicity implies ongoing coping problems for the family and the child. The impact of a chronic illness or handicapping condition on a family system is usually more disintegrative than integrative, disrupting the lives of all family members and exacerbating the developmental risks to the child. It is not surprising that a recent comprehensive study for establish ing public policies for children with chronic illness at Vanderbilt Univer sity has called attention to these factors and produced, as a primary recommendation, increased attention to the psychological impact of dis ease on the family and the child. In this context there is an important need for adequate assessment of psychological and behavioral problems in these children to plan for appropriate services."

One of the most obvious changes that has occurred in behavioural biology in recent years is that it has become conspicuously a problem orientated subject. Moreover, one of the most impor tant consequences of this has been to stimulate interdisciplinary links between evolutionary biology, zoology, ecology, anthro pology and psychology. The time is now right to ask questions which relate whole animals in the contexts of their ecosystems, with their social behaviour and development, with their perceptual and cog nitive capacities. These are new ways of looking at old problems, but we are still at the stage of finding out what kinds of questions to ask. For several years now I have been involved in teaching behavioural biology to students of psychology as well as zoology, and have greatly appreciated the opportunity to relate material across many different subject areas. It is the interfacing of prob lems, as in ecology and psychology for example, that makes 'more sense' of topics such as 'intelligence', responses to 'novelty', feeding strategies and socialleaming. The aim of the book is to provide readily digestible information in a number of areas of current interest in behavioural biology. Above all, it is intended to provide a basis for discussion and further inquiry."

If the reader will excuse a brief anecdote from my own intellectual history, I would like to use it as an introduction to this book. In 1957, I was a sophomore at an undergraduate liberal arts college major ing in medieval history. This was the year that we were receiving our first introduction to courses in philosophy, and I took to this study with a passion. In pursuing philosophy, I discovered the area called "philosophical psychology," which was a Thomistic category of inquiry. For me, "philosophical psychology" meant a more intimate study of the soul (psyche), and I immediately concluded that psychology as a discipline must be about this pursuit. This philosophical interest led me to enroll in my first introductory psychology course. Our text for this course was the first edition of Ernest Hilgaard's Introduction to Psychology. My reasons for entering this course were anticipated in the introductory chapter of Hilgaard's book, where the discipline and its boundaries were discussed, and this introduction was to disabuse me of my original intention for enrolling in the course. I was to learn that, in the 20th century, people who called themselves psychologists were no longer interested in perennial philosophical questions about the human psyche or person. In fact, these philosophical questions were considered to be obscurantist and passe. Psychology was now the "scientific" study of human behavior. This definition of psychology by Hilgaard was by no means idiosyncratic to this introductory textbook."

As a follow up to Volume 7, contributors continue to explore the latest developments in developmental psychology. Here, researchers focus on the integration of theory and research and evaluates theoretical progress and advanced research. Continuing with the successful format of previous volumes in Annals of Theoretical Psychology, Volume 10 presents four major contributions--each accompanied by commentaries and replies to commentaries.

This volume is the eighth in the Research Advances Series and the fifth published by Plenum Press. The purpose of the series is to review new work in rapidly changing fields. We do not expect reviews to cover the whole field of work on alcoholism and addiction. Nor do we expect that they will be like annual reviews covering all work in a delimited field. Our reviews are designed to explore only the most exciting parts of the total field and to focus on conclusions that can be made about them. The series publishes one volume each year. Volume 8 is an omnibus rather than a theme volume in that a wide range of topics is covered, including research on alcohol, opiates, and tobacco. As usual, the greater emphasis is on alcohol research, reflecting the importance of the problem and the volume of work to be reviewed. With Volume 8 come some changes in the Editorial Board. It will be the last volume in the series for Robert E. Popham who has resigned from the Board. He has been with the series since its inception and has contributed a great deal to its development. The members of the Board are grateful for his help. We are adding two new members: Dr. Howard Cappell, whose field is experimental psychology, and Dr. Edward M. Sellers, in clinical medicine and pharmacology.

Proceedings of a conference of experts on cocaine addiction, this early volume documents the devastating effects of crack, then a new cocaine preparation, and its extraordinary addicting properties. The Bahamian experience with crack provided an early warning about the extreme personal and social dangers of this drug .

Each of the three great schools of developmental psy- chology represented in this vo1ume--psychoana1ytic, cogni- tive-developmental, and Vygotskian--diverges in important ways. But more recent changes in each discipline have led to new possibilities for theoretical integrations. Each ori- entation has begun to focus upon the problem of "meaning construction", that is, how a person's subjectivity and con- sciousness is created through his interaction with signifi- cant others. Each discipline also discovered that as it switched to meaning and interpretation as the foci of their work, they had to reformulate and, in some cases, reject po- sitions taken by their founding figures. The papers in this volume attempt to describe the newest developments in each of these fields and to foster a theoretical dialogue around the concept of the self. The papers in this book emerged out of discussions at a Conference on the Self, sponsored by the Center for Psychosocial Studies in Chicago. For the psychoanalytic and cognitive-developmental ap- proaches, we can observe a transition from what we call the bio10gism of both traditional Freudian and Piagetian memta- psychologies to a more "communicative-interactionist" point of view. Psychoanalysts have focused on the subjective expe- rience of their patients as constituting a reality in its own right, and therefore have always focused upon problems of communication and interpretation. But Freud's emphasis on bio-sexua1 development led him to create a metapsycho1ogy in which the basic organizing principle is that of drive re- duction.

In the past twenty years there have been many new developments in the study of animal behaviour: for example, more sophisticated methods of neurophysiology; more precise techniques for assessing hormonal levels; more accurate methods for studying animals in the wild; and, on the functional side, the growth of behavioural ecology with its use of optimality theory and game theory. In addition, there has been a burgeoning number of studies on a wide range of species. The study of aggression has benefited greatly from these develop ments; this is reflected in the appearance of a number of specialized texts, both on behavioural ecology and on physiology and genetics. However, these books have often been collections of papers by spe cialists for specialists. No one book brings together for the non specialist all the diverse aspects of aggression, including behavioural ecology, genetics, development, evolution and neurophysiology. Neither has there been a comparative survey dealing with all these aspects. Therefore one of our aims in writing this book was to fill in these gaps. Another of our aims was to put aggression into context with respect to other aspects of an animal's lifestyle and in particular to other ways in which animals deal with conflicts of interest. Aggressive behaviour does not occur in a biological vacuum. It both influences and is influenced by the animal's ecological and social environment, so we consider both the complex antecedent conditions in which aggressive behaviour occurs, and its ramifying consequences in the ecosystem."

Wolves are charismatic emblems of wilderness. Dogs, which descended from wolves, are models of urbanity. Do free-ranging dogs revert to pack living or are their societies only reminiscent of a wolfish heritage? Focusing on behavioral ecology, this is the first book to assess societies of both gray wolves and domestic dogs living as urban strays and in the feral state. It provides a comprehensive review of wolf genetics, particularly of New World wolves and their mixture of wolf, coyote and dog genomes. Spotte draws on the latest scientific findings across the specialized fields of genetics, sensory biology, reproductive physiology, space use, foraging ecology and socialization. This interdisciplinary approach provides a solid foundation for a startling and original comparison of the social lives of wolves and free-ranging dogs. Supplementary material, including a full glossary of terms, is available online at www.cambridge.org/9781107015197.

InJuly 1982 the first Dartmouth workshop on the corpus callosum took place. A nucleus of basic and clinical scientists was convened to give progress reports of their work on the corpus callosum. This text was subsequently compiled by the various participants from these reports modified by a stimulating cross fertilization of ideas and subsequent studies. Four and one-half decades have intervened since Van Wagenen first sectioned the corpus callosum for epilepsy (Van Wagenen and Herren, 1940) and Erickson (1940) demonstrated that the corpus callosum is the major route for generalization of experimentally induced focal cortical epilepsy. During the succeeding 45 years a handful of clinicians has pursued these leads to confirm the therapeutic value of callosotomy for some types of medically intractable generalized epilepsy. Parallel experimental studies with a number of epilepsy models have indicated that the corpus callosum is indeed the major route for seizure generalization, that the brainstem is a secondary and more resistant pathway for seizure generalization, and that most if not all epileptic seizures originate from the cerbral cortex. The unexpected clinical finding that even partial (focal) seizure incidence is modified by callosotomy now has been demonstrated in the laboratory. The various contributors to the clinical and experimental epilepsy sections of this volume have been seminal in these elucidations, as will be evident from their chapters. The section on the development, anatomy, and physiology of the corpus callosum demonstrates that these basic areas of study have not been neglected.

In Children and Other Wild Animals, bestselling novelist Brian Doyle (Mink River, The Plover) describes encounters with astounding beings of every sort and shape. These true tales of animals and human mammals (generally the smaller sizes, but here and there elders and jumbos) delightfully blur the line between the two. In these short vignettes, Doyle explores the seethe of life on this startling planet, the astonishing variety of our riveting companions, and the joys available to us when we pause, see, savor, and celebrate the small things that are not small in the least. Doyle’s trademark quirky prose is at once lyrical, daring, and refreshing; his essays are poignant but not pap, sharp but not sermons, and revelatory at every turn. Throughout there is humor and humility and a palpable sense of wonder, with passages of reflection so true and hard earned they make you stop and reread a line, a paragraph, a page. Children and Other Wild Animals gathers previously unpublished work with selections that have appeared in Orion, The Sun, Utne Reader, High Country News, and The American Scholar, as well as Best American Essays (“The Greatest Nature Essay Ever”) and Best American Nature and Science Writing (“Fishering”). “The Creature Beyond the Mountain,” Doyle’s paean to the mighty and mysterious sturgeon of the Pacific Northwest, won the John Burroughs Award for Outstanding Nature Essay. As he notes in that tribute to all things “sturgeonness”: “Sometimes you want to see the forest and not the trees. Sometimes you find yourself starving for what’s true, and not about a person but about all people. This is how religion and fascism were born, but it’s also why music is the greatest of arts, and why stories matter, and why we all cannot help staring at fires and great waters.”
