Through this volume, the history of the emergence of behaviorology is available both for the first time (in 1992) and comprehensively. As current today as when originally written, this book is unique because it is also the only analyzed historical treatment of the emergence of the independent natural science of behavior written during the early years of that disciplinary emergence by participant-observes of that emergence.

This book is thus persistently timely in both the uniqueness of the authors’ perspective and because it provides generations of readers with lessons about the origins and developments of natural sciences in general and of a natural science of behavior in particular.

As a natural science discipline on the life science continuum, behaviorology is the science and technology of environment-behavior relation. First, it discovers the variables that are in “casual” relationships with the behavior of individuals during their lifetime. Then it designs and implements changes to these accessible variables bringing beneficial change and expansion to the individual’s behavior repertoire. This contingency engineering contributes to all human endeavors (e.g., child care, education, work, diplomacy, even science itself) and address vital questions: “Why does human behavior happen, and what can make it better?”

This book reviews, in historical context, the incompatible paradigms and philosophies among disciplines addressing the behavior of individuals. In familiarizing the reader with the history of behaviorology’s emergence, and disciplinary components, this book also makes further comprehension and application of behaviorology’s science and technology easier and more effective and beneficial.
