This Brief synthesizes findings from recent experiments on jealousy in infants with insights from pioneering thinkers in developmental science. It discusses attachment issues, status of jealousy as an emotion and as a feature of temperament, underpinnings in social cognition, the development of adaptive versus maladaptive presentations, and facets of jealousy that may be part of a normal repertoire of coping strategies. This unique volume also identifies facial, vocal, and bodily responses associated with jealousy as well as situations of differential treatment by caregivers that may bring them about. This knowledge is as useful in studying children's emotional development as it is in addressing jealousy-based challenges in growing families. Among the featured topics: Jealousy in infants, defended and defined. A theory of jealousy as temperament. Sadness, anger, fear, and love. Individual differences and normativity. Child and contextual influences on individual differences. Implications for clinical intervention: preparing for a sibling's arrival. Jealousy in Infants is an essential resource for researchers, clinicians, and graduate students in developmental psychology, infant mental health, and social psychology.

This unique volume is one of the first of its kind to examine infancy through an evolutionary lens, identifying infancy as a discrete stage during which particular types of adaptations arose as a consequence of certain environmental pressures. Infancy is a crucial time period in psychological development, and evolutionary psychologists are increasingly recognizing that natural selection has operated on all stages of development, not just adulthood. The volume addresses this crucial change in perspective by highlighting research across diverse disciplines including developmental psychology, evolutionary developmental psychology, anthropology, sociology, nutrition, and primatology. Chapters are grouped into four sections: Theoretical Underpinnings Brain and Cognitive Development Social/Emotional Development Life and Death Evolutionary Perspectives on Infancy sheds new light on our understanding of the human brain and the environments responsible for shaping the brain during early stages of development. This book will be of interest to evolutionary psychologists and developmental psychologists, biologists, and anthropologists, as well as scholars more broadly interested in infancy.
