ABSTRACT
This chapter deals with two problems that may be counted among the most timely topics in modern scientific study of the child: the development of a child's perception of the external world, and the formation of cultural skills. It is concerned with the ways a child establishes contact with the external world and how he becomes part of the system constituting his environment. Psychologists have known that at about the time a child's behavioral processes begin to be organized, the first signs of organized attention appear, and the child begins to single out particular objects in the external world and fix his gaze and, if one may use the term, his entire behavior on them. How does a child learn to count? Posing the question in this way will help us to follow the development of counting processes in the child.
