DESCRIPTION:Stratal-cyclic models (e.g.\, Stratal OT\, Lexical Phonology) 
 allow for\nphonological processes to apply in multiple domains\, adding an
 other potential dimension for phonological change as a process’s domain 
 may change with time. Post-nasal plosive deletion in English (Borowsky 199
 3) is an example of a process that narrowed its domain over time\, applyin
 g first at only the phrase level\, then at the phrase and word levels\, an
 d finally at the phrase\, word\, and stem levels (Bermudez-Otero\, 2011). 
 I'll present a productivity-based\ncomputational acquisition model that ca
 n explain why such\ndomain-narrowing changes occur and demonstrate through
  simulation that it will iteratively reanalyze post-nasal plosive deletion
  in the same sequence as the observed change. The model suggests that in o
 rder for this change to proceed\, two things are required: ambiguity in th
 e input as to in which level deletion occurred\, and restrictions on phras
 e-level processes such as resyllabification. I'll also examine the model's
  prediction that in languages with lower stem/word-level ambiguity than En
 glish similar changes will not proceed to the stem level.
