language and (sharply bounded) memory
We are developing theories of the mental architecture that supports language processing—especially the short-term memory system that allows us to keep in mind and revise the partial interpretation (or generation) of earlier parts of a sentence while relating it to the rest. Our recent work advances and empirically defends (through detailed cross-linguistic studies of reading, including eye-tracking) a number of specific hypotheses about the principles that govern how this memory system works.
A key feature of this work is that the proposed principles—such as similarity-based interference and a sharply limited focus—are general ones that have broad explanatory power in domains outside of sentence processing. Our theories of sentence processing are intended to explain how we are functionally able to comprehend and produce complex language structures despite these constraints, and to understand precisely how the constraints leave their mark on linguistic behavior.
The work touches on a number of core issues in sentence processing, including the complexity of embedded structures, processing of verb-final structures, and reanalysis.
