Research Projects
My primary research interest is the role of variation in spoken language
processing.
Effects of Geographic Mobility on Lexical
Processing and Perceptual Adaptation
My current major project is an exploration and refinement of Clopper and
Walker's (2017) proposal that geographic mobility contributes to changes in
lexical processing dynamics, in which mobile listeners consider more lexical
competitors over a longer period of time than non-mobile listeners. The project
addresses (1) the specificity of the processing mechanism underlying the
differences in lexical processing dynamics between geographically mobile and
non-mobile listeners; (2) the nature and timing of dialect exposure that is
required to observe changes in lexical processing dynamics; and (3) the
implications of geographic mobility for short-term perceptual adaptation to
novel variation. A summary of this project is available on the Geographic Mobility and Lexical Processing
Project website. (Supported by the National Science Foundation BCS 1843454.)
Effects of Linguistic and Indexical Sources of
Variation on Speech Processing
A second major long-term project examines the combined effects and interactions
among linguistic and indexical sources of variation on speech processing. One
branch of my work in this area explores the interactions among phonetic
reduction, dialect variation, and linguistic sources of variation, including
lexical competition and semantic context, in speech production and perception.
The other branch examines the effects of experience with linguistic variation
on cross-dialect speech perception and processing. Many of my experiments
involve speech samples from The
Nationwide Speech Project Corpus and the Ohio State Stories Corpus.

Perception of Socio-Indexical Information Across
the Lifespan
In collaboration with Dr. Laura Wagner
in the Department of Psychology at Ohio State, I have extended my earlier work
on perceptual dialect classification to children as young as four years old.
Our research uses explicit classification, language attitudes, and
cross-dialect intelligibility tasks to explore when children perceive and
interpret information in the acoustic speech signal to make judgments about
social categories, such as region of origin, and how the perception of regional
dialect variation changes over the course of the lifespan. A summary of the
results of this project is available on the ORDDR
Project website. (Partially supported by a Seed Grant from the Ohio State Center for Cognitive and Brain Sciences.)
Prosodic Variation in American English
In collaboration with Dr. Rajka
Smiljanic in the Department of Linguistics at the University of Texas, I am
working on an examination of regional prosodic variation in American English,
including intonation and temporal organization. (Partially supported by a
Coca-Cola Critical Difference for Women Faculty Grant.)
Research Opportunities for Undergraduates
|
Undergraduate
research assistants are always welcome in my Speech Perception Lab. Students
can earn credit in LLING 4998(H) (Undergraduate Research) for work in the
lab. Paid positions are also sometimes available. Students do not need to be
a linguistics major to work in the lab, but some coursework in linguistics or
a related field (speech and hearing science, psychology, cognitive science)
is preferred. If you are interested in working on any of the projects
described above, please contact me to discuss research opportunities. |

Non-Academic Interests
When I'm not doing research, I enjoy traveling. My most recent travel
adventures have taken me to Lisbon, Philadelphia, and Mackinac Island.
I'm also a college basketball junkie. I follow Duke basketball with a passion, but I'll watch pretty much any game at the college level.
