My ideas for this book have been evolving over the last several years as I have been working in the animal modeling area and have seen it change rather dramatically. There have been tremendous advances, both in methodology and in conceptualization, yet the literature is scattered in journals encompassing many disciplines. In particular, there have been only very limited attempts to write about the philosophical, conceptual, and controversial issues in this field; to pull together diverse findings; and to provide some general perspective on its future. As will probably be apparent, I am a clinical psychiatrist who also has a fundamental interest in animal behavior, especially primate social behavior. I entered the field from a clinical research standpoint to devel- op some animal models of depression after being stimulated to do so by Dr. William Bunney, then at the National Institute of Mental Health and now at the University of California-Irvine. The field has grown rapidly since then and there is considerable research activity. Indeed, the re- search activity has grown more rapidly than our conceptualization of what animal models are and are not. Animal preparations are now available for studying specific aspects of certain types of psychopathology. Thoughtful workers in the animal modeling field no longer talk about comprehensive models but rather about more limited experimental preparations in animals for studying certain specific aspects of human psychopathology.
