This accessible book explains how individuals develop through their relationships with others. Alan Fogel demonstrates that human development is driven by a social dynamic process called co-regulation—the creative interaction of individuals to achieve a common goal. He focuses on communication—between adults, between parents and children, among non-human animals, and even among cells and genes—to create an original model of human development.

Fogel explores the origins of communication, personal identity, and cultural participation and argues that from birth communication, self, and culture are inseparable. He shows that the ability to participate as a human being in the world does not come about only with the acquisition of language, as many scholars have thought, but begins during an infant's earliest nonverbal period. According to Fogel, the human mind and sense of self start to develop at birth through communication and relationships between individuals.

Fogel weaves together theory and research from a variety of disciplines, including psychology, biology, linguistics, philosophy, anthropology, and cognitive science. He rejects the objectivist perspective on development in favor of a relational perspective: to treat the mind as an objective, mechanical thing, Fogel contends, is to ignore the interactive character of thinking. He argues that the life of the mind is a dialogue between imagined points of view, like a dialogue between two different people, and he uses this view to explain his relational theory of human development.

Developing through Relationships makes a substantial contribution not only to developmental psychology but also to the fields of communication, cognitive science, linguistics, and biology.

The Ontogeny of Information is a critical intervention into the ongoing and perpetually troubling nature-nurture debates surrounding human development. Originally published in 1985, this was a foundational text in what is now the substantial field of developmental systems theory. In this revised edition Susan Oyama argues compellingly that nature and nurture are not alternative influences on human development but, rather, developmental products and the developmental processes that produce them.
Information, says Oyama, is thought to reside in molecules, cells, tissues, and the environment. When something wondrous occurs in the world, we tend to question whether the information guiding the transformation was pre-encoded in the organism or installed through experience or instruction. Oyama looks beyond this either-or question to focus on the history of such developments. She shows that what developmental “information” does depends on what is already in place and what alternatives are available. She terms this process “constructive interactionism,” whereby each combination of genes and environmental influences simultaneously interacts to produce a unique result. Ontogeny, then, is the result of dynamic and complex interactions in multileveled developmental systems.
The Ontogeny of Information challenges specialists in the fields of developmental biology, philosophy of biology, psychology, and sociology, and even nonspecialists, to reexamine the existing nature-nurture dichotomy as it relates to the history and formation of organisms.
