"It does not make much sense to speak of what a person `really' sees, because we have so many different agencies." How do children's drawings of people evolve? Minsky describes a scheme which involves relatively minor changes to the drawing program.
"I suspect that after children learn to make recognizable figures, they usually move on to face the problems of representing much more complicated scenes. As they do this, we should continue to appreciate how well children deal with the problems they set for themselves. They may not meet our own grown-up expectations, but they often solve their own versions of the problems we pose."
(NB: This illustrates a kind of reformulation (of the drawing routine), but not WHY it occurs, which is a question that keeps coming to mind for me.)
