I investigate the basic cognitive processes that underly word recognition and sentence comprehension. My research interests include the psychology of language; sentence comprehension, word recognition & discourse processing. How is syntactic knowledge stored and accessed? What is the relationship between syntactic and semantic processing? How are linguistic ambiguities resolved? Under what circumstances is unambiguous linguistic input difficult to comprehend? I am also interested in how grammatical knowledge is represented for people who speak more than one language, or more than one dialogue of the same language.
