Written by a group of developmental scientists, this book debates cognitive achievements in early infancy from a multidisciplinary perspective. The editors combine knowledge from different areas of infant development research to present an integrated view of the cognitive abilities emerging in early infancy. The chapters are arranged in a sequence that best conveys to the reader the line of reasoning that emerged during the development of this book. The book opens with chapters dealing with fundamental and general aspects of cognitive development, sweeps through the specific theme of language acquisition, and closes by returning to general questions concerning different representation modalities.

Regression periods play a central role in the psychological development of the human baby. Studies of infants have identified 10 periods of regression, or a return to a high frequency of mother-infant contact, within the first 20 months of life. These periods of emotional insecurity in the child signal forthcoming periods of developmental advance and the emergence of an array of new skills as a consequence of parent-infant conflict over body contact and the renegotiation of old privileges. Although the basic idea in this book is an old one, the authors believe that regression periods deserve further study and have identified four questions of central importance today: *Can the phenomenon of regression periods as found by Dutch researchers in 1992 be replicated in other countries and cultures? *What environmental conditions have an effect on these regression periods and how? *Are there physical conditions in infants that show a non-linear distribution over age similar to regression periods? *Have brain changes been detected since the review of Fischer & Rose (1994) at other ages than the six reported by them, and, if yes, how do these relate to the ages at which regression periods are found? Forming the core of this book, the replication studies performed in Sweden, Spain, and England provide support that regression periods are a rreliable phenomenon and should be dealt with accordingly whenever developmental processes in infancy are discussed.

This book summarizes more than four decades of research on imitation in infancy and its relation to early learning and sociocognitive development in typically and atypically developing children. The studies were carried out in a Scandinavian context and thus provide important cultural validation of the central developmental processes. The book is divided into three parts: Part one focuses on the social and cognitive aspects of imitation, discussing links to early parent-infant interaction, and developmental meaning. It addresses evidence for an imitative capacity at birth for typical and atypical infants. Also covered are early individual differences in imitation, the role of imitation as a social and cognitive learning mechanism in early development, and possible links between imitation and temperament. Part two presents unique longitudinal studies on early memory development using deferred imitation as the key method. It discusses the biological basis of memory and explores the idea that deferred imitation is an indicator of an infant's ability to understand intentions. Part three focuses on imitation in young children with autism and with Down syndrome. It examines the role of imitation as a "deficit" as well as a vehicle for change when used interactively in early interventions for children with autism. Imitation from Infancy Through Early Childhood is an essential resource for researchers, professors, and graduate students as well as clinicians and other professionals in developmental psychology, cognitive development, psycholinguistics, child psychiatry, and developmental neuroscience.
