The authors’ work in clinical and forensic psychology has brought them into contact with various forms of interpersonal conflict and confrontation. One issue that is clear in practice, but not so in research and writing, is that of female aggression and violence. It has been noted that the ways in which female aggression is observed, perceived, and manifested is different to the ways in which male aggression is addressed. There is also a paucity of research and commentary on female aggression, and this topic is only just beginning to be tackled by feminist, social, psychological and medical interpretations of the human discourse. Approaching these using a holistic perspective, this book will examine the evolution, development and expression of aggression in female animals and humans. The authors will not merely contrast female aggression with the behaviour of male counterparts, but also examine this phenomenon as an emotional, physical or psychological response to the world in its own right, not merely as a pale imitation of male behaviour.
