Research on the development of human infants has revealed remarkable capacities in recent years. Instead of stressing the limitations of the newborn, the modern approach is now more optimistically based on an assessment of the adaptive capabilities of the infant. Innate endowment, coupled with interaction with the physical and social environment, enables a developmental transition from processes deeply rooted in early perception and action to the cognitive and language abilities typical of the toddler.; This book reviews a number of issues in early human development. It includes a reconceptualization of the role of perception at the origins of development, a reconciliation of psychophysical and ecological approaches to early face perception, and building bridges between biological and psychological aspects of development in terms of brain structure and function. Topics covered include basic exploratory processes of early visual systems in early perception and action; face perception in newborns, species typical aspects of human communication, imitation, perception of the phonetic structure of speech, origins of the pointing gesture, handedness origins and development, theoretical contributions on perception and cognition, implicit and explicit knowledge in babies; sensory-motor coordination and cognition, information processing and cognition, perception, habituation and the development of intelligence from infancy.

This book examines the contrast sensitivity of the human visual system - concerning the eye's ability to distinguish objects from each other or from the background - and its effects on the imageforming process. The text provides equations for determining various aspects of contrast sensitivity, in addition to models that easily can be used for practical applications.

The developing infant can accomplish all important perceptual tasks that an adult can, albeit with less skill or precision. Through infant perception research, infant responses to experiences enable researchers to reveal perceptual competence, test hypotheses about processes, and infer neural mechanisms, and researchers are able to address age-old questions about perception and the origins of knowledge. In Development of Perception in Infancy: The Cradle of Knowledge Revisited, Martha E. Arterberry and Philip J. Kellman study the methods and data of scientific research on infant perception, introducing and analyzing topics (such as space, pattern, object, and motion perception) through philosophical, theoretical, and historical contexts. Infant perception research is placed in a philosophical context by addressing the abilities with which humans appear to be born, those that appear to emerge due to experience, and the interaction of the two. The theoretical perspective is informed by the ecological tradition, and from such a perspective the authors focus on the information available for perception, when it is used by the developing infant, the fit between infant capabilities and environmental demands, and the role of perceptual learning. Since the original publication of this book in 1998 (MIT), Arterberry and Kellman address in addition the mechanisms of change, placing the basic capacities of infants at different ages and exploring what it is that infants do with this information. Significantly, the authors feature the perceptual underpinnings of social and cognitive development, and consider two examples of atypical development - congenital cataracts and Autism Spectrum Disorder. Professionals and students alike will find this book a critical resource to understanding perception, cognitive development, social development, infancy, and developmental cognitive neuroscience, as research on the origins of perception has changed forever our conceptions of how human mental life begins.
