6 Preface This volume is an attempt to integrate the theory and data of social and personality development within a modem evolutionary framework. The various chapters are not meant to be read in isolation from one another but rather are intended to form an integrated whole. There is thus a great deal of cross-referencing between chapters and to some extent they all stand or fall together. This also suggests that the accuracy (or usefulness) of a particular chapter cannot be judged until the book is comprehended as a whole. Chapter 1 deals with the theoretical foundations of this enterprise, and the focus is on the compatibility of mainstream approaches within the field to a modem evolutionary approach. Chapters 2-4 concern what I view to be the fundamental proximal mechanisms underlying social and personality development. Chapter 2, on temperament and personality development, is particularly central to the rest of the volume because these processes are repeatedly invoked as explanatory concepts at later points in the volume. If the theory of temperament is one central pillar of the volume, Chapter 5, on family processes, is the other. The perspective developed there on the evolution of the family is central to much of the discussion in Chapter 6 on aggression and sex differences as well as the discussion of the development of altruism in Chapter 8. Chapter 5 is the first chapter to emphasize modem evolutionary theory and the remaining chapters continue and expand this perspective in several of the central areas of social development, including moral reasoning (Chapter 7) and the wider context of human development (Chapter 9). This work culminates a long process of attempting to develop a unified account of social and personality development based on evolutionary theory. It draws on a wide range of theory and data, and I have benefited from the help of a great many individuals in trying to put it together. None of this would have been possible without the help of Ross Parke. The time I spent at the University of Illinois on a postdoctoral fellowship and the discussions we had exposed me to a great many ideas that have found their way into this book. Since coming to California State University-Long Beach, I have also benefited greatly from conversations with Robert Thayer on the subject of personality, and his work is a major part of the theory developed in the Appendix to Chapter 2. The other major influence in the areas of temperament and personality development has been Mary K. Rothbart. The more I thought about these issues and my own data, the more I realized that vii

7 viii PREFACE she had developed a theory which was powerful enough to incorporate the central data on personality development and was yet simple enough to incorporate into an adaptationist account of personality. Her critical comments on Chapter 2 and several other chapters are greatly appreciated. I would also like to thank Virginia Douglas for her critical reading of Chapter 2 and for her encouragement in the area of the linkages between the theory of temperament and conceptualizing clinical diagnoses. One of the main purposes behind the book is to integrate modem evolutionary theory with the data and theory of developmental psychology. In this endeavor I have benefited greatly from the help and encouragement of William Charlesworth, a true pioneer in the area of applying models and ideas deriving from evolutionary biology to the area of child development. His work is responsible for the prominence in this volume of thinking in terms of resources as being fundamental to an evolutionary approach. This aspect of the book has also benefited from the work of sociobiologically oriented researchers on child development, including Jerome Barkow, Robert Burgess, James Chisholm, Patricia Draper, Henry Harpending, Dennis Krebs, Jeffrey Kurland, Charles Lumsden, Nancy Segal, Martin Smith, and Glenn Weisfeld. I have tried to feature their work and integrate it with the other areas of social and personality development. Another source of help in this area has been Michael McGuire whose critical readings of earlier versions of several of the chapters were very helpful. I would also like to thank Richard Lerner, who has given me the opportunity to develop several of the ideas presented here and whose work in the area of plasticity and early experience parallels my own work. Finally, thanks of another kind must be given to my wife Susan who has patiently put up with several relocations and the need to adjust her own academic career to mine. Her encouragement has been indispensable. My children, Joshua and Geoffrey, also deserve a great deal of credit, since they have served as unwitting case studies in my ongoing attempt to understand temperament and personality. It has been said that every parent with more than one child believes in the importance of temperament, and I am no exception. Long Beach, California KEVIN B. MACDONALD
