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 person- ality 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.
