Evidence for distributivity effects in comprehension.

In the current article, we introduce a new methodology for detecting whether a word in a sentence is conceptually represented as plural and use it to shed light on a debate about whether comprehenders interpret singular indefinite noun phrases within a distributed predicate as plural during online reading. Experiment 1 extended a methodology previously used by Berent, Pinker, Tzelgov, Bibi, and Goldfarb (2005) to test individual words or word pairs by having readers judge, at a critical word, whether 1 or 2 words appeared on a computer screen while performing self-paced reading on a sentence presented in 1- and 2-word chunks. In line with Berent et al., Experiment 1 indicated that participants were slower to judge that 1 word was on the screen when the word was plural (e.g., cats) than when it was singular (e.g., cat). Experiment 2 used this paradigm to show that readers build different conceptual representations for distributed versus collective predicates and interpret a singular indefinite noun phrase within a distributed predicate as plural (e.g., Kaup, Kelter, & Habel, 2002; but cf. Filik, Paterson, & Liversedge, 2004; Paterson, Filik, & Liversedge, 2008). PsycINFO Database Record (c) 2010 APA, all rights reserved.
