Biography

Cynthia Fisher received her Ph.D. from the University of Pennsylvania in 1989. She is a professor in the U of I Department of Psychology, and a part-time faculty member in the Beckman Institute Cognitive Science group. Her fields of professional interest are language acquisition, speech perception, and language comprehension.

Research

In learning a language a child cracks a code, interpreting sequences of arbitrary elements (words) without prior knowledge of the words or their rules of combination. During only a few years of ordinary exposure to the use of a language, a child becomes a native speaker, capable of combining and recombining words in various syntactic structures to speak and understand entirely new messages. Fisher's work focuses on three related questions about this feat of learning: First, how do children develop representations and processes for identifying spoken words? Second, how do children learn to identify syntactic patterns in speech? And third, how do children use their developing knowledge of syntactic patterns to assign meanings to sentences? In all three areas, her work attempts to determine how a young language learner could be led by relatively superficial or perceptible features of utterances to develop ever more abstract representations of language.

For example, Fisher's research on sentence interpretation reveals that even 2-year-olds can use the structure of a sentence to constrain its interpretation. If we remove relational, semantic information from a sentence by using an unfamiliar (made-up) verb, children can still interpret the sentence in accord with its structure: They interpret transitive (e.g., "She's pilking her over there!") and intransitive verbs ("She's pilking over there!") as referring to different aspects of the same motion event. Recent data also suggest that 2-year-olds can use word order in transitive sentences to constrain interpretations of sentences containing unfamiliar verbs. This work suggests that children can construct quite abstract representations of sentence structure at an early age, and can use these representations of structure to narrow their choices in interpreting a sentence. Research on the perception of spoken words and sentences suggests that flexible lexical representations, both context-sensitive and permitting abstraction across contexts, are a natural result of mechanisms by which language processing systems adapt to reflect linguistic experience.

To examine children's representations and interpretations of linguistic input, Fisher uses a variety of methods to tap the growing lexical and syntactic knowledge of children between one and four years of age. These methods include tracking the direction of children's gaze as they watch two synchronized videos and listen to a sentence that describes only one of them, asking children to select a named object, and measuring the accuracy with which children can identify and repeat spoken words or sentences.

Fisher's major sources of funding are the NIMH, NICHD, and NSF.
