Integrating cutting-edge research from multiple disciplines, this book provides a dynamic and holistic picture of the developing infant mind. Contributors explore the transactions among genes, the brain, and the environment in the earliest years of life. The volume probes the neural correlates of core sensory, perceptual, cognitive, emotional, and social capacities. It highlights the importance of early relationships, presenting compelling findings on how parent-infant interactions influence neural processing and brain maturation. Innovative research methods are discussed, including applications of behavioral, hormonal, genetic, and brain imaging technologies.
