I have now finished the book; my gestalt is coming into completion. Throughout the months that I have been writing this, I have, indeed, been intrinsically motivated. Now that it is finished I feel quite competent and self-determining (see Chapter 2). Whether or not those who read the book will perceive me that way is also a concern of mine (an extrinsic one), but it is a wholly separate issue from the intrinsic rewards I have been experiencing. This book presents a theoretical perspective. It reviews an enormous amount of research which establishes unequivocally that intrinsic motivation exists. Also considered herein are various approaches to the conceptualizing of intrinsic motivation. The book concentrates on the approach which has developed out of the work of Robert White (1959), namely, that intrinsically motivated behaviors are ones which a person engages in so that he may feel competent and self-determining in relation to his environment. The book then considers the development of intrinsic motiva tion, how behaviors are motivated intrinsically, how they relate to extrinsically motivated behaviors, and how intrinsic motivation is affected by extrinsic rewards and controls. It also considers how changes in intrinsic motivation relate to changes in attitudes, how people attribute motivation to each other, how the attribution process is motivated, and how the process of perceiving motivation (and other internal states) in oneself relates to perceiving them in others. The book assumes that there is personal knowledge (i.e., that persons have access to their own internal states in a way in which v VI Preface others do not}. However, it also shows that these internal states are changeable and that cognitive processes represent one means by which they change. The emphasis of the book is on cognitive processes, and the reasons for this are simple: Not only do cognitions affect internal states such as attitudes and motives, but, as this work shows, individuals choose what behaviors to engage in on the basis of their cognitions about the outcomes of those and other behaviors. This work is intended as a source book on intrinsic motivation; it has attempted to draw together from many areas of psychology all of the available literature related to intrinsic motivation. Differ ent aspects have been the subjects of varying degrees of attention, and this is largely a reflection of my own interest. The book is appropriate for use as a textbook for upper-level courses and seminars in human motivation, social cognition, and social psychol ogy. In Chapter 8 some of the applications of research and theory on intrinsic motivation are considered, especially as they relate to the areas of education and organizational motivation. Throughout the book I have employed the referent pronoun "he" in the generic sense, i.e., to refer to such nouns as "person." I have done so, despite the current criticism of this usage as sexist, because there is to my mind no really satisfactory alternative available to the writer. The use of "they" to refer back to "person" is grammatically incorrect, and the use of "he or she" is rather cumbersome for repeated use throughout a work of this length. I originally began investigating the area of intrinsic motiv(!tion about five years ago when I was a second-year graduate student in the Psychology Department at Carnegie-Mellon University. At that time Vic Vroom was very supportive and helped me begin to formulate my ideas on the topic. I began writing the book about two years ago while working as a part-time research associate in the Management Research Center at the University of Rochester. Bernard Bass, director of the Center, provided the financial support which enabled me to begin this book, and Wayne Cascio and Carl Benware were at that time working actively with me on the research reported in Chapters 5, 9, and 10. To all these people I acknowledge my gratitude. I wrote most of the book during the 1973-1974 academic year, with the financial support of an interdisciplinary postdoctoral Preface VII fellowship at Stanford University granted by the National Institute of Mental Health. I am grateful to both Stanford and the NIMH for providing me with a stimulating (and sunny) environment for working on this project. Elliot Aronson read the entire manuscript and made many useful suggestions. I appreciate his help and his friendship. I would also like to acknowledge the aid of Daniel Berlyne, who commented on the entire manuscript; Ralph Haber and Zur Shapira, who read several chapters; Edward Walker, who contrib uted to Chapter 2; Doug Stern and Ned Dwelle, who made suggestions about Chapter 1; David Elkind, who offered feedback on Chapter 3; and Eileen Zucker, who reviewed Chapter 10. Charles (Skip) Lowe helped enormously by making extensive comments on an early version of Chapter 10, and David Landy worked with me in developing some of the ideas presented in Chapter 7. I appreciate the intellectual and personal companion ship of both these colleagues very much. During the first few months that I worked on this book, I was living in a commune with six other psychologists: Drs. Harold Bernard, Ken Cohen, Sandy Ehlinger, Judy Krusell, David Landy, and Allan Schwartz. Their love and support was at times distract ing, nonetheless it provided me with energy to live and work enthusiastically. To them, and to the rest of the "extended Canterbury"-Nancy Wickens-Thies, Lou Morrice, Amanda Mor rice, Louise Sheinman, and Mitchell Bernard-this book is affec tionately dedicated.
