This book is far more technical and should be considered advanced among those that are attempting to understand body language.

I am a contributor to this book and know many of the other authors therein, but receive no
compensation from its sale. Having declared this possible conflict of interest, I can recommend
purchase of this book if you are interested in learning what can be discovered from the face
through measurement of facial muscular action in scientific research. Its approximately 500
pages contains 22 scientific articles, mostly published previously in journals, that report
research studies conducted in the late 1970s to the early 1990s, most towards this later date.
These articles cover a diverse range of topics, methods, and principles having to do with the
relationship between facial expression and emotion; clinical diagnosis, treatment, and outcome;
and other related issues. The editors's selection process, based on the use in the study of the
Facial Action Coding System (FACS, a method for measuring facial behavior), has included
competent research with above average interest, thoughtful reflection, theoretical and practical
relevance, and plain good sense that generally exceeds what you might find, for example, in your
typical social psychology journal. The authors of the articles work in many places around the
world and represent most of the people in the vanguard of the FACS movement and the new
approaches to studying behavior and emotion. This book is particularly helpful if you are new to
the study of facial behavior or have not been diligent in collecting the important articles using
facial measurement, which are published many different journals. The book provides an efficient
vehicle to catch up on the significant issues, findings, trends, and controversies in the areas
covered, including the quality and usefulness of the information provided by the face, the
relationship of facial expression to emotion, whether emotion is a coherent response system,
differences between genuine and false smiles, expression in pathological states, affect in the
psychotheraputic process, etc. The included works provide a solid foundation for understanding
how facial measurement contributes to investigating behavioral science problems. Even in the
unlikely event that you have previously read all the published works reprinted here, this volume
has value because each chapter has at least one afterward that expands on the original work in
revealing and useful ways that bring you up to date on the topic, and there is one thought
provoking article by Ekman et al. on the relation between facial behavior and psychiatric
outcomes that you will not find elsewhere. Also, the editors include their own new chapters
introducing, and finally, summarizing and integrating the works included. A table of contents,
forward by M. Brewster Smith, original source references, author list, and a lengthy subject
index are included. Take a look at the table of contents provided on this site to see more
details. The overall statement of this book is that the face contains important data about
concepts that are vital to diverse behavioral science issues. You will find that the perspective
of this book is different from several other books on facial expression currently in print. If
you are contemplating research on emotion, facial behavior, non-verbal behavior, and related
topics, this book is a helpful guide containing useful background; if you are currently planning
research in these fields, it is indispensible reading.
