Behaving like the other sex has been observed in a number of species of mammals, although such behaviour is generally more common in the female than the male. This study discusses why such capacity is so common in sexually differentiated animals. The contributors gather together information on the generation of heterotypical sexual behaviour and on certain forms of aggression. They provide a review of the current state of knowledge from both animal experimentation and human clinical studies, looking at the role of physiological mechanisms and experiences in such controversial topics as the...

An Advanced Study Institute on the Biology of Aggression was held in glorious weather between the twenty-first and thirtieth of July 1980, at the Chateau de Bonas, Gers, France. The Institute was arranged by a scientific organizing committee consisting of Drs. Paul Brain and David Benton of the University College of Swansea, Wales, U.K. This book reflects the papers presented at the A.S.I., and the arrangement of the book parallels the pro gramme. The particular objective was to concentrate on recent research on aggression from the viewpoint of the diverse biological disciplines that have...

Etienne E. Baulieu* The theme of this book, Heterotypical Behaviour in Man and Animals, should be of great interest to physiologists, endocrinolo- gists, physicians, and workers in social sciences. Although Heterotypical Sexual Behaviour is a major theme, this volume attempts to display wide interest in reproductive medicine, general physiology, and behaviour in the two sexes. The editors explore the psycho-social dimension, not only of sexuality, but of eroticism which, as recalled by John Money, has its etymological root in the Greek word for love. Being an endocrinologist, who has studied...

. Aggression research is in a rapid state of development. The accelerating knowledge of neurotransmitter systems in the brain, their behavioural functions and the development of drugs which may specifically affect systems related to attack and defence is fruitfully combined with studies in which basic ethological observation and quantification techniques are used more routinely. Moreover, much of the experimental effort has finally applied some order to the initial chaos which afflicted the various experimental aggression models used in pharmacological, physiological and ethological research....
