We propose a model for a lexically located syntactic processor that makes available multiple morphological verb forms in parallel. Although modular in architecture, it differs from the modular serial parser proposed by Frazier. It could easily be extended to allow for post-access contextual selection of the appropriate verb form, thus avoiding the Minimal Attachment garden path. The model suggests that the nature of the contextual effect, as detailed by Altmann and Steedman, is lexical selection. Several empirical issues involving frequency asymmetries of the verb forms, the speed of retrieval and inhibition, and interactions with context are discussed. We have built a connectionist implementation of the model that runs on a variety of input stimuli, producing results not incompatible with the effects reported both by Altmann and Steedman (in press) and Ferreira and Clifton (1986).
