This book and the symposium on which it was based were designed to cross the boundaries of subdiscipline and theoretical orientation to address four critical issues in understanding development: explanation of change and development; the nature and process of change; forms of variability in performance; and the promotion of change through application.

The chapters suggest that change and development in target systems from cells to selves, may not be explainable, assessable, or promotable without careful reference to the context (social and otherwise) of the system, and that the process of change and development may involve variability of the system in addition to periods of stability. Together the chapters harken back to the spirit of the grand theory.

Instead of proposing a grand theory, they provide an excellent foundation for considering the importance of an individual's (or particular group's) context and variability, and discussions to facilitate thinking about what still needs to be worked out.

Language, Literacy, and Cognitive Development addresses the impact of language and literacy on cognitive development. Top researchers examine the cognitive significance of the growth in children's ability to express themselves symbolically, whether that involves communicating linguistically, mathematically, logically, or through some other symbol system expressed in speech, gesture, notations, or some other means. The book contributes to refining and answering questions regarding the nature, origin, and development of symbolic communication in all its forms, and their consequences for the cognitive development of the younger child at home and the older child at school.

This book explores the central importance of adolescents' own activities in their development. This focus harkens back to Jean Piaget's genetic epistemology and provides a theoretically coherent vision of what makes adolescence a distinctive period of development, with unique opportunities and vulnerabilities. An interdisciplinary and international group of contributors explore how adolescents integrate neurological, cognitive, personal, interpersonal, and social systems aspects of development into more organized systems.
