Actually there has been a connectionist theory of categorization proposed.
Like me it has fallen into obscurity, but it can be found in:

Moran, Michael A., A Perceptual Model of Episodic Memory and its
   Explanation of Recognition and Categorization. Dissertation Abstacts
   International, 1983.

Sorry I don't have the DAI volume and number.  It is also available at the
U.C. Davis main library.

I proposed a structure and process for categorization and related this
to both categorization effects and to word frequency effects, drawing a
parallel between the results found in these two generally separate lines of
research.  A mechanism was proposed that would explain a large number of
results in both lines of work.
