Introduction

The papers presented in this volume, written by active and well-known researchers, discuss experimental research that has validated the importance of infancy in individual development over the age continuum.

Overview of Conceptual Models

In addition, a diverse overview section contains informative chapters on conceptual models for individual differences during infancy including:

• individual differences from the perspective of dynamical systems theory
• the logic of behavioral genetic designs and their use in the delineation of genetic contributions to individual differences
• coverage of basic statistical treatments for individual difference data focussing on cluster analytic techniques
