How does memory for recent words interact with expectations generated during sentence comprehension? Recent work has provided empirical support to the idea that context actively modulates lexical access by impacting comprehenders' expectations about the identity of upcoming words. However, very little work has been done to address whether and how lexical and contextual factors combine during sentence processing. I will present an electrophysiological experiment that our group (MERP) conducted to examine the contribution of two of these factors, word repetition and sentence predictability, and I will introduce a novel paradigm that we designed to test for these effects.
