Hey so does this sound interesting to anyone else?  anyone interested in
reading and discussing it?  there's a great new little garden cafe i
recently found, and we could sit in nice comfy chairs in the sunshine, drink
decent coffee, and rip it to shreds - I mean, discuss it objectively.

Using learnability as a filter on factorial typology: a new approach to
Anderson and Browne's generalization

Abstract:
ABSTRACT. This article investigates the learnability filter
(LF) hypothesis, according to which the set of logically
possible grammars predicted by linguistic theory is reduced
to a proper subset of learnable grammars by external principles
of language learning. Anti-faithfulness constraints (Alderete,
2001a) provide a linguistic theory that predicts the existence
of circular chain shifts of two segment types, including
purely phonological exchanges that are unattested cross-linguisti
cally (Anderson and Browne, 1973). Overt data representing
such systems are fed into a standard OT learning model in
which learners have IO-antifaithfulness constraints at their
disposal. Despite this evidence and these constraints, learners
always select grammars in which segmental exchanges are
restricted to morphologically defined environments, consistent
with typological findings. These results are shown to have
implications for the nature of constraints in Optimality
Theory, the correct analysis of morpho-phonological alternations,
and a host of representational assumptions in phonology
and morphology.

SUPPLEMENT. The overt forms of the two linguistic typologies
developed here (test typology I and test typology II) are
included in a separate PDF document.
