Understanding or “reading” Schematic Representations

In his long essay on communicating with illiterates, A. Fuglesang argues that certain concepts, on which the scientific approach to problem solving is based, do not exist among illiterates. He concludes from the test scarried out in Zambia that concepts of the conservation of mass, number and of are a do not exist or are unstable, as are the concepts of a straight line, horizontality and verticality among illiterates. In general the determining factor for the development of such concepts is the educational stimulation of the environment and where the stimulation is lacking the basic symbol processes are lacking.
