Summary: REVIEW
How Infants View Natural Scenes Gathered
From a Head-Mounted Camera
Richard N. Aslin*
ABSTRACT
The role of early visual experience in human infant development has been inferred primarily by studies of visual
deprivation (e.g., cataracts). Another approach, described here, is to provide a detailed description of the visual input
gathered by normal infants in their natural environment. Recently, several labs have begun the laborious process of
obtaining video images from a head-mounted camera to provide an infant's eye-view of their visual world. Preliminary
findings from one such study are reviewed and discussed in the context of the power and limitations of this approach for
revealing important insights about the role of early visual experience, as well as the broader implications for studies of
cognitive, language, and social development.
