Elizabeth Bates

Elizabeth Ann Bates (1947-2003) was an American cognitive scientist and professor at the University of California, San Diego who became a leading authority on how children acquire language and how language is organized in the brain. After earning her doctorate in human development from the University of Chicago in 1974 and teaching at the University of Colorado, she joined UCSD, where her research combined developmental psychology, linguistics, and neuroscience. With Brian MacWhinney she developed the competition model, which explains language processing as the outcome of competing cues, word order, word meaning, and grammatical markers, that speakers weigh differently across languages, rather than as the product of a fixed innate grammar. Her studies of children who had suffered early brain injury showed that they could still acquire language in largely normal ways, evidence that language ability is distributed across general cognitive and neurological processes rather than confined to dedicated brain modules, a finding that challenged strongly nativist accounts of language acquisition. Over her career she wrote ten books and more than two hundred peer-reviewed articles and helped establish cognitive science as a recognized academic discipline before her death from pancreatic cancer in 2003.
