ABSTRACT
We should like to know how infants see and think about their worlds. Do their perceptions of objects and events agree with ours? Can we find evidence that the manner in which they perceive follows the same rules that govern the perceptions of adults? Or, if infant vision differs from that of the adult, then when does it mature into the adult condition? This is of course not a new set of questions, but there have been some new approaches to answering them and new motivation for asking them. In the following discussion I shall give an overview of the research, in particular that of my colleagues and me, done recently in an effort to answer these questions.
