Language and Cognition

Readers actively construct representational models of meaning when reading text, and they do so by drawing on a range of kinds of information, from the specifi c linguistic forms of the sentences to knowledge about how the world works (Ferretti, Kutas, & McRae, 2007 ; Madden & Zwaan, 2003 ). The present set of studies focused on how grammatical aspect is integrated into a situation model and how it is connected to other dimensions of model construction. In three experiments, participants were asked to complete sentences with a choice of grammatical aspect form (perfective or imperfective). The test sentences systematically varied four dimensions of the sentence that were linked to grammatical aspect in diff erent ways: telicity and transitivity (both linked through their semantic representations), subject animacy (linked through an inference over semantic representations), and related location information (linked through an inference grounded in world knowledge). In addition, to examine the infl uence of discourse function (backgrounding vs. foregrounding) on aspectual choice diff erent construction types were varied across experiments – specifi cally a fronted locative construction and the presence of a generic narrative opener ( Once upon a time ). The results found that aspectual choice depends on information linked to the semantic representation of grammatical aspect; however, in contrast to previous work (e.g., Ferreti et al., 2007) information grounded in world knowledge (location information) did not infl uence aspectual choice except when it was integrated in a specialized discourse construction.
