The American child today or the TV child is 
brought up in a world of scanning rather than 
looking, of total involvement in audile-tactile 
experiences which appeal to all of his senses. This 
kind of total involvement of his whole sensorium is 
in complete contrast to the specialist training of 
the literate schoolroom. But the TV child of North 
America is being brought up by television imagery 
in a world of outlines that are flat and audile-
tactile.
