A related paper is :
Mark Weiser and Joan Shertz. "Programming problem representation
	in novice and expert programmers." International Journal of
	Man-Machine Studies.  December 1983. pp. 391-398.
This paper is an application of some of the Chi, Feltovich, and Glaser
methodology to the problem space of programming, with generically
similar results.  Differences in detail include categories of
problem-solving used and not used by experts (algorithms yes,
data-structures no), and differences between expert programmers
and expert former programmers now programming managers.
