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.

In psychology, motivation refers to the initiation, direction, intensity and persistence of behaviour. Motivation is a temporal and dynamic state that should not be confused with personality or emotion. Motivation is having the desire and willingness to do something. This book presents research in this field.

This volume covers the current status of research in the neurobiology of motivated behaviors in humans and other animals in healthy condition. This includes consideration of the psychological processes that drive motivated behavior and the anatomical, electrophysiological and neurochemical mechanisms which drive these processes and regulate behavioural output. The volume also includes chapters on pathological disturbances in motivation including apathy, or motivational deficit as well as addictions, the pathological misdirection of motivated behavior. As with the chapters on healthy motivational processes, the chapters on disease provide a comprehensive up to date review of the neurobiological abnormalities that underlie motivation, as determined by studies of patient populations as well as animal models of disease. The book closes with a section on recent developments in treatments for motivational disorders.

Wolves excitedly greet each other as members of the pack come together; a bumble bee uses its long tongue to reach the nectar at the base of a foxglove flower; a mongoose swiftly and deftly bites its prey to death; young cheetahs rest quietly together, very close to sleep. Now in full colour, this revised and updated edition of Manning and Dawkins' classic text provides a beautifully written introduction to the fundamentals of animal behaviour. Tinbergen's four questions of causation, evolution, development and function form the fundamental framework of the text, illustrated with fascinating examples of complex behavioural mechanisms. The authors provide accounts of all levels of behaviour from the nerve cell to that of the population. The strengths of An Introduction to Animal Behaviour as a textbook include its clear explanations and concise, readable text and the enthusiasm of the authors for their subject.

The practical focus of this authoritative, comprehensive encyclopedia promotes the understanding and improvement of animals' behaviour without compromising welfare. It will be an essential resource for practising veterinarians, researchers and students in zoology and ethology, and for all those working with and interested in animals and their welfare. --Book Jacket.
