Language Production in Unimpaired and Brain-Damaged Populations
When we produce an utterance, we usually produce it without error. Sounds correctly form words that are in the right order (according to the grammatical rules of the language), which correspond to the ideas we want to convey. Out of a spoken vocabulary of 40,000 words, how do we successfully select and order words during fluent speech? What are the brain mechanisms that support this ability, and how do they break down in an acquired language disorder like aphasia? Viewed very broadly, selecting and ordering words is relevant to how we retrieve and order all mental representations, from recognizing a face in a crowd, to catching a ball with the correct hand movements. Investigators in the Schnur laboratory will use a combination of behavioral (testing unimpaired speakers), neuropsychological (studying aphasic speech), and neuroscience (functional and structural brain imaging) methods in order to answer these questions.
