The implications of early experience for children’s brain development, behavior, and psychological functioning have long absorbed caregivers, researchers, and clinicians. The 1989 fall of Romania’s Ceausescu regime left approximately 170,000 children in 700 overcrowded, impoverished institutions across Romania, and prompted the most comprehensive study to date on the effects of institutionalization on children’s wellbeing. Romania’s Abandoned Children, the authoritative account of this landmark study, documents the devastating toll paid by children who are deprived of responsive care, social interaction, stimulation, and psychological comfort. Launched in 2000, the Bucharest Early Intervention Project (BEIP) was a rigorously controlled investigation of foster care as an alternative to institutionalization. Researchers included 136 abandoned infants and toddlers in the study and randomly assigned half of them to foster care created specifically for the project. The other half stayed in Romanian institutions, where conditions remained substandard. Over a twelve-year span, both groups were assessed for physical growth, cognitive functioning, brain development, and social behavior. Data from a third group of children raised by their birth families were collected for comparison. The study found that the institutionalized children were severely impaired in IQ and manifested a variety of social and emotional disorders, as well as changes in brain development. However, the earlier an institutionalized child was placed into foster care, the better the recovery. Combining scientific, historical, and personal narratives in a gripping, often heartbreaking, account, Romania’s Abandoned Children highlights the urgency of efforts to help the millions of parentless children living in institutions throughout the world.

A new understanding of cognitive development from the perspective of neuroscience This book provides a state-of-the-art understanding of the neural bases of cognitive development. Although the field of developmental cognitive neuroscience is still in its infancy, the authors effectively demonstrate that our understanding of cognitive development is and will be vastly improved as the mechanisms underlying development are elucidated. The authors begin by establishing the value of considering neuroscience in order to understand child development and then provide an overview of brain development. They include a critical discussion of experience-dependent changes in the brain. The authors explore whether the mechanisms underlying developmental plasticity differ from those underlying adult plasticity, and more fundamentally, what distinguishes plasticity from development. Having armed the reader with key neuroscience basics, the book begins its examination of the neural bases of cognitive development by examining the methods employed by professionals in developmental cognitive neuroscience. Following a brief historical overview, the authors discuss behavioral, anatomic, metabolic, and electrophysiological methods. Finally, the book explores specific content areas, focusing on those areas where there is a significant body of knowledge on the neural underpinnings of cognitive development, including: * Declarative and non-declarative memory and learning * Spatial cognition * Object recognition * Social cognition * Speech and language development * Attention development For cognitive and developmental psychologists, as well as students in developmental psychology, neuroscience, and cognitive development, the authors' view of behavioral development from the perspective of neuroscience sheds new light on the mechanisms that underlie how the brain functions and how a child learns and behaves.
