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…

Semantic roles are a critical aspect of linguistic knowledge because they indicate the relations of the participants in an event to the main predicate. Experimental studies on children and adults show that both groups use associations between general semantic roles such as Agent and Theme, and grammatical positions such as Subject and Object, even…

This article explored the way people and connectionist models could apply knowledge of the structure of one domain to another.

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…
