The term "recursion" is used in at least four distinct theoretical senses within cognitive science. Some of these senses in turn relate to the different levels of analysis described by David Marr some 20 years ago; namely, the underlying competence capacity (the "computational" level), the performance operations used in real-time processing (the…

Previous studies have examined cross-serial and embedded complement clauses in West Germanic in order to distinguish between different types of working memory models of human sentence processing, as well as different formal language models. Here, adult plasticity in the use of these constructions is investigated by examining the response of…

Focuses on the brain's response to one aspect of syntactic processing--the processing of sentences that violate constraints on constituent movement. Findings indicate that movement constraints can be applied during the earliest stages of sentence processing, perhaps in conjunction with the creation of phrase structure.

This study compared the production of complex syntax by 16 older adults diagnosed with probable Alzheimer's disease and 25 age-matched control subjects. It found that although individuals diagnosed with Alzheimer's disease did not produce frank lexical or grammatical errors, they did find it difficult to access the "best fit" between meaning and…

Demonstrates how the definition of "simple attachment" and "tree lowering," operations related to the grammatical composition operations of "substitution" and "adjunction" in the Tree Adjoining Grammar formalism, yields a parser more constrained than previous description theory based models. The article…

Notes that in linguistic theory, phenomena previously handled by a separate grammatical component have been moved into the lexicon and that in some theories, the contrast between grammar and the lexicon has vanished. Concludes that the case for a modular distinction between grammar and the lexicon has been overstated and that the evidence to date…

Presents the results of three experiments investigating the time course of grammaticality judgement. The high correlations among the experiments suggest that the incremental tasks assigned were tapping into the same decision-making process as is found online. The article discusses the findings' implications for the error types that do and do not…
