In this article, I examine the literature from three domains of cognitive development in the first years of life — mathematics, categorization and induction — to determine whether infants possess concepts that allow them explicitly to reason and make inferences about the objects and events in the world. To achieve this aim, I use the distinction between procedural and declarative knowledge as a marker for the presence of access consciousness. According to J.M. Mandler, infants' early concepts are represented as accessible (...) declarative knowledge. However, the evidence discussed in this article indicates that infants' early concepts are best depicted as procedural, perceptually-based knowledge that are inaccessible to consciousness. I conclude by speculating about the role of language development on the emergence of consciousness towards the end of the second year of life. (shrink)

The cognitive revolution in the 1950s and 1960s led researchers to view the human mind--like a computer--as an information-processing system that encodes, represents, and stores information and is constrained by limits on hardware and software. The emergence of new behavioral, computational, and neuroscience methodologies, has deeply expanded psychologists' understanding of the workings of the infant, child, and adult mind. One result is that research has focused on mechanisms of change, over developmental time, in the information-processing mind.In this book, Lisa Oakes, (...) Cara Cashon, Marianella Casasola, and David Rakison bring together the recent findings and theories about the origins and early development of the information-processing mind, and provide insight into the future directions in the study of infant perception and cognition. The contributors represent a wide-range of research areas in the study of infant perception and cognition, who emphasize the use of diverse methodological techniques to address key questions about development. Their chapters demonstrate how the combination of historical perspectives on the information-processing approach to cognition and recent advances in behavioral, computational, and neuroscience approaches to cognition has contributed to our understanding of how abilities ranging from visual attention to face processing to object categorization have developed during infancy. Across this broad range of topics, it is clear that much of our modern understanding of infant perceptual and cognitive development emerges from the foundation of classic information-processing models of development, such as that of Leslie B. Cohen. The recent advances illustrated in this book show how researchers have built on this foundation to uncover the mechanisms that drive developmental change. (shrink)
