On the nature of alternations in phonological acquisition

Dinnsen, Daniel A., and Laura W. McGarrity. 2004. On the nature of alternations in phonological acquisition. Studies in Phonetics, Phonology and Morphology. 10.1. 23. 41. This paper brings first-language acquisition evidence to bear on a guiding principle of phonology, namely the Alternation Condition, and identifies some problems with its integration into both rule-based and constraint-based theories of phonology. It has long been held that neutralization rules apply only in derived environments and that no phonological rule can apply exclusively in a nonderived environment. Three problematic case studies are considered. In the first of these, a process is shown to apply exclusively in a nonderived environment. The second case involves a different process that is also restricted to a nonderived environ-ment but requires an extended notion of what constitutes a (non)derived environment. The third case finds the same process to be restricted to a derived environment, but again requires the extended interpretation of (non)derived environments. Optimality theoretic accounts of these phenomena are formulated to take advantage of developmental changes in morphology and constraint rankings. (Indiana University)
