                      ABSTRACT

 This report contains three papers on symbol processing in connectionist
networks.  The first two, ``A Computational Basis for Phonology'' and
``Rationale for a `Many Maps' Phonology Machine,'' present the latest
results of our ongoing project to develop a connectionist explanation for
the regularities and peculiarities of human phonological behavior.  The
third paper, ``Rule Representations in a Connectionist Chunker,''
introduces a new rule chunking architecture based on competitive learning,
and compares its performance with that of a backpropagation-based chunker.
Earlier work in these areas was described in report CMU-CS-89-158, ``Rules
and Maps in Connectionist Symbol Processing.''

``A Computational Basis for Phonology'' and ``Rule Representations in a
Connectionist Chunker'' will appear in D. S.  Touretzky (ed.), Advances
in Neural Information Processing Systems 2, the collected papers of the
1989 IEEE Conference on Neural Information Processing Systems - Natural and
Synthetic, Denver, CO, November 1989, Morgan Kaufmann Publishers.

``Rationale for a `Many Maps' Phonology Machine'' will appear in the
Proceedings of EMCSR-90: the Tenth European Meeting on Cybernetics
Systems Research, Vienna, Austria, April 1990, World Scientific Publishing
Co.
