ABSTRACT
This chapter describes research carried out at Minnesota on several related aspects of the development of spatial sensitivity. It reviews work on the development of sensitivity to binocular information. The chapter deals with sensitivity to information for the approach of an object and the development of avoidant responses, such as blinking and head withdrawal, that could reveal the presence of spatial sensitivity. It also describes work on the development in infants of sensitivity to static pictorial spatial information. Although perception may be the oldest field of psychology, and although speculation on the spatial perception of infants has had a very long history in philosophy. One of the most pressing problems in investigating the onset of sensitivity to depth information is to find a meaningful response available to the young infant that is a clear indicator of depth sensitivity.
