An important aspect of communicating a message is coming up with an appropriate combination of words. A lot of work in language production has focused on how we access and combine words (or signs). I’m interested in the mapping problem of selecting words to represent a message, and especially in how the semantics of the message are divided (or not) among multiple words in an utterance. What production plans are we learning if we’re able to dynamically adapt to such a wide range of semantics and fairly rigid syntactic rules? Eventually I’d like to think about these issues in cross-modal contexts (sign vs. spoken language).
Two important sources for how we choose the order of our words are the lifelong experience we have with language (for example, English sentences tend to be ordered subject-verb-object), and the more immediately recent things we’ve heard or said. For example, previous passive sentences will encourage you to say your next sentence in passive-voice. Maryellen MacDonald, Federica Bulgarelli, Daniel Weiss and I are looking at how similar these planning effects are to that of other complex plans humans execute, such as ordering a series of actions in service of a goal like reaching for or touching an object. Our preliminary work suggests that when multiple options are available both touching a series of dots and saying a sentence are similarly biased by previous experience.
A new area of inquiry for me is in the mapping problem. Talking about something includes choosing the words to represent what you mean. Words can vary in how appropriately they capture your intended message. For example, you might refer to a cat as kitty, Whiskers, or the little furball. Some labels might be more appropriate for what you’re trying to convey and some labels might be easier to generate. How do these competing factors interact? By testing how much speakers are willing to compromise the accuracy of what they say for the ease of saying it, we can get a nuanced sense of what parts of speaking are more carefully planned, or more important to the speaker.
Past Research Projects
My first project with Maryellen looked at the relationship between the properties of the words themselves and how this affects the structure of what is said. We asked native speakers of English to communicate silently using gestures of their own invention. One reason communicating with your hands is different from your mouth is that it is possible to visually depict complex relationships with a single handsign, when it would normally take a combination of spoken words to do. For example, imagine gesturing (compared to verbally describing) a person throwing a football. We showed participants 20 scenes depicting events of similar complexity (a person doing something with/to an object), and most participants spontaneously invented a single complex gesture depicting these relationships. While these gesture productions were lacking many properties of languages, they suggest that the communicative task of describing the relationship between multiple entities, such as a person acting on an object, does not require a word for each, if the language system can represent the complex information in one fell swoop.
At the University of St. Thomas I explored discourse factors that affect the frequency of co-speech gestures. We wanted to know how co-speech gesture varied within a conversation as a function of listener feedback, and found that listener requests for repair produced more co-speech gestures relative to listener affirmations.
Lately I’ve been curious about cheeses and what new kinds I might like. I’ve been taking photographs of abandoned buildings and playing rhythmically on my piano for a while now. People have gifted me a lot of elephant knick-knacks over the years, so I’ve taken an interest in trying to come up with a new animal that I like. I spend a lot of my free time thinking about how to bridge gaps and inspire new perspectives on things like hearing status and (my) military experience. I also enjoy rearranging the furniture in my house.
