There are a lot of threads on comp.lang.python that mention beginners' possible reactions to language features, so I'll mention this paper relating to teaching programming: <http://www.cs.mdx.ac.uk/research/PhDArea/saeed/>. The early draft which I've read, <http://www.cs.mdx.ac.uk/research/PhDArea/saeed/paper1.pdf>, references quite a lot of literature on what new programmers do, discusses a new test for programming aptitude.
