This long-awaited and ground-breaking book from cognitive scientist John Morton helps to clarify the nature of developmental disorders. It challenges the basis of standard behaviourally based diagnostic practice, showing how the role of biology and cognition is crucial to understanding the underlying nature of these disorders. It also sets out a clear method for assessing and comparing the many alternative theories.

An understanding of developmental disorders depends on being able to address the issue of cause and on making the link between disorder and normal process. These were the driving forces behind the emergence of the causal modelling methodology at the Cognitive Development Unit in London by the author and his colleague Uta Frith. John Morton elucidates this method and uses it ruthlessly to compare different theories of particular developmental disorders and to pinpoint their weaknesses. The result is a book that will have a profound impact on research and thinking in the fields of psychology, neuroscience and medicine.

In this collection scholars, policymakers, and military officials explore the conditions that gave rise to the Balkan wars in the 1990s, the application of international law to the wars, the conduct of the wars, and post-war issues. The essays are based on presentations given at the International Conference on the Balkans held at Florida Atlantic University in February 2002. The contributors come from varied backgrounds, including international law, genocide studies, peacekeeping, European politics, communications, history, and military studies.

Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.

This handbook covers the most common paediatric problems encountered in Accident and Emergency departments. The contents include cardiopulmonary resuscitation, major trauma, fractures and other orthopaedic problems, burns, scalds and poisoning. Child abuse and its recognition and management are described. Emphasis has been placed on the emergency management of serious illness and injury and on the management of common problems. In many cases, further management is described for those studying for the Accident and Emergency Fellowship examination. This edition includes a revised section on paediatric resuscitation which summarizes the latest guidelines in this area. The section on major trauma has been extended to follow the Advanced Paediatric Life Support guidelines, and the section on fractures is now in tabular format for the comparison of possible diagnoses.

P. Marler* and H. S. Terrace** *The Rockefeller University Field Research Center Millbrook, NY 12545 **Dept. of Psychology, Columbia University New York, NY 10027, USA For the first half of this century, theories of animal conditioning were regarded as the most promising approach to the study of learning - both animal and human. For a variety of reasons, disillusionment with this point of view has become widespread during recent years. One prominent source of disenchantment with conditioning theory is a large body of ethological observations of both learned and unlearned natural behavior. These challenge the generality of principles of animal learning as derived from the intensive study of a few species in specialized laboratory situations. From another direction, the complexities of human language acquisition, surely the most impressive of learned achievements, have prompted developmental psychologists to doubt the relevance of principles of animal learning. Even within the realm of traditional studies of animal learning, it has become apparent that no single set of currently available principles can cope with the myriad of new empirical findings. These are emerging at an accelerating rate from studies of such phenomena as selective attention and learning, conditioned food aversion, complex problem solving behavior, and the nature of reinforcement. Not very surprisingly, as a reaction against the long-held but essentially unrealized promise of general theories of learning, many psychologists have asked an obvious question: does learning theory have a future? 2 r.
