RESEARCH INTERESTS

Language, Memory, and Attention

Collaborators: Duane Watson and Aaron Benjamin

Since people cannot attend to and remember everything, they must identify the most important pieces of information they hear. I am investigating how various cues in speech, like prosodic stress and disfluency, affect what listeners pay attention to and what listeners remember. For example, an utterance like "The REPORTER won an award for covering the robbery" suggests that what's most important is that the reporter, and not someone else, won the award. But, "The reporter won an award for covering the ROBBERY" suggests that what's important is that the award was won for covering the robbery, and not some other story. I am investigating exactly how these cues affect memory and how the use of this information differs across the lifespan.

Disfluency

Collaborators: Duane Watson, Nazbanou Nozari, Gary Dell

A second line of research concerns disfluencies, or interruptions in regular speech. When we speak, we often encounter problems like saying "uh" and "um," repeating words we have already said, or interrupting ourselves to correct something we said previously. Although these are different types of disfluencies, we currently do not know much about how these types are the same or different from one another. I am conducting work exploring how various kinds of disfluencies differ and how they may reflect different problems or processes in language production.

Executive Attention and Language Acquisition

Collaborators: Mary Rothbart, Michael Posner, Brad Sheese, Lauren White

Individual differences in executive attention have been found to affect how children acquire language, but the specific ways in which attention affects language acquisition are still unclear. One possibility is that attention helps with the information processing demands of vocabulary acquisition, such as attending to new words and stimuli in the environment and mapping those words to the stimuli. We are currently exploring the relationship between executive attention and language acquisition in greater depth as part of a longitudinal study of the first four years of life.
