ABSTRACT
Many different lines of evidence point to radical changes in the performance and organization of infants' spatial vision over the first few months of life. In some cases, the evidence allows us to characterize the changes quite well, and to suggest the nature of the developments in underlying visual mechanisms. In the second section of this chapter we review some evidence from our own studies, which points to the establishment, between birth and 3-4 months of age, of a range of mechanisms having selective responses to particular spatial properties of the visual input.
