Complex cognitive skills such as reading and calculation and complex cognitive achievements such as formal science and mathematics may depend on a set of building block systems that emerge early in human ontogeny and phylogeny. These core knowledge systems show characteristic limits of domain and task specificity: Each serves to represent a particular class of entities for a particular set of purposes. By combining representations from these systems, however human cognition may achieve extraordinary flexibility. Studies of cognition in human infants (...) and in nonhuman primates therefore may contribute to understanding unique features of human knowledge. 2020 APA, all rights reserved). (shrink)

This article views face perception as the ideal case study example for understanding the deeper principles underlying human neurodevelopment. It illustrates how face perception has been one of oldest battlegrounds for resolving key issues in human development. It argues that taking a developmental approach to face perception can resolve some of the major current debates in the adult face perception and cognitive neuroscience literature. Thus, face perception and development continue to be mutually informative domains of study. The work on newborns (...) designed to test the “innate knowledge” of faces, studying the development of face perception skills during infancy and childhood, has proved to be fertile ground for domain-general theories of perceptual and cognitive development. The study reviews recent literature on the factors that contribute to the specialization of certain cortical areas for face processing. It suggests an intriguing alternative middle-ground view in this polarized debate. (shrink)

Human development takes place in a social context. Two pervasive sources of social information are faces and hands. Here, we provide the first report of the visual frequency of faces and hands in the everyday scenes available to infants. These scenes were collected by having infants wear head cameras during unconstrained everyday activities. Our corpus of 143 hours of infant-perspective scenes, collected from 34 infants aged 1 month to 2 years, was sampled for analysis at 1/5 Hz. The major finding (...) from this corpus is that the faces and hands of social partners are not equally available throughout the first two years of life. Instead, there is an earlier period of dense face input and a later period of dense hand input. At all ages, hands in these scenes were primarily in contact with objects and the spatio-temporal co-occurrence of hands and faces was greater than expected by chance. The orderliness of the shift from faces to hands suggests a principled transition in the contents of visual experiences and is discussed in terms of the role of developmental gates on the timing and statistics of visual experiences.
