Formal theories of mental representation have receded from the importance they had in the early days of cognitive science. I argue that such theories are crucial in any mental domain, not just for their own sake, but to guide experimental inquiry, as well as to integrate the domain into the mind as a whole. To illustrate the criteria of adequacy…

The ability to generate novel utterances compositionally using generative knowledge is a hallmark property of human language. At the same time, languages contain non-compositional or idiosyncratic items, such as irregular verbs, idioms, etc. This dissertation asks how and why language achieves a balance between these two systems--generative and…

Argues that generative phonology is not predictive of phonological identification, thus preventing it from achieving descriptive adequacy and limiting its value in explaining human speech perception. The assumption that the unity of the morpheme must be expressed phonologically is rejected. (Author/EJS)

This research is based on the assumption that a Spanish/English bilingual is aware of the phonological and semantic relatedness of the many hundreds of pairs of transparently cognate items in the two languages. This awareness is linguistically significant in that it is reflected in the internalized grammar of the bilingual. The bilingual speaker…

The internalized grammar of the bilingual is different from that of a monolingual. The bilingual has, in addition to the entries that are proper to each of the two languages he speaks, certain union entries. These are extensive in the case of the Spanish/English bilingual since there are many items in the two languages that manifest systematic…
