Word integration and regression programming during reading: a test of the E-Z reader 10 model.

Participants read sentences with two types of target nouns, one that did and one that did not require a determiner to form a legal verb-noun phrase sequence. Sentences were presented with and without the critical determiner to create a local noun integration difficulty when a required determiner was missing. The absence of a required determiner did not influence 1st-pass reading of the verb, the noun, and the posttarget word. It did, however, have a profound effect on 2nd-pass reading. All three words were a likely target of a regression when a required determiner was missing, and the noun and the posttarget word were likely sources of a regression. These results are consistent with novel E-Z reader model assumptions, according to which identification of the noun should be followed by its integration, and integration difficulties can lead to the initiation of a regression to the noun. However, integration difficulties influenced eye movements earlier and later than predicted by the new model. PsycINFO Database Record (c) 2009 APA, all rights reserved.
