In case you missed the call on LINGUIST List, Andries Coetzee is organizing a workshop on Experimental Approaches to Optimality Theory at UMich, with René Kager and Joe Pater as invited speakers. From the call for papers:

Over the past few decades, experimental data have been used increasingly as evidence in phonological theorizing. This is no less true of Optimality Theory (OT) as is evidenced by the growing body of OT literature that uses experimental data. The purpose of this workshop is twofold. On the one hand, we want to investigate the extent to which experimental data can be used to fine-tune OT analyses. On the other hand, we want to consider the challenges that non-categorical experimental data may pose to OT.

[…] For the purpose of this workshop, we give a broad interpretation to “experimental approaches”, so that it includes experiments as diverse as psycholinguistic/processing tasks (word-likeness, phoneme identification, lexical decision, etc.), as well acoustic/articulatory experiments. We also do not want to limit contributions to papers that argue for OT. Papers that use experimental evidence to point out shortcomings of OT are equally welcome. Lastly, it is not required that a submission contributes new experimental data. Papers that deal with the general challenges posed to OT by non-categorical experimental data can also be submitted.
