This article examines cognitive process models of human sentence comprehension based on the idea of informed search. These models are rational in the sense that they strive to quickly find a good syntactic analysis. Informed search derives a new account of garden pathing that handles traditional counterexamples. It supports a symbolic explanation for local coherence as well as an algorithmic account of entropy reduction. The models are expressed in a broad framework for theories of human sentence comprehension.
