What role does the body play with language? My research investigates this question from different perspectives using different methods, but it is built on a single theoretical framework. Working from the position that language is an embodied ability that evolved from bodily communication systems (gestures, facial expressions, eye gaze, etc.) in our evolutionary past, my work investigates how language interacts with the body in present-day communication.
I focus primarily on hand gestures that spontaneously accompany speech. These gestures are interesting because they occur simultaneously with speech but reflect meaning in a distinct way from words.
For example, the form and movement of different drinking gestures—a gentle movement with a small precision grasp depicts sipping from a sake cup whereas a more abrupt movement with a closed fist depicts drinking from a large beer mug—capture the meaning of these two actions in a direct
way. In contrast, spoken words reflect meaning only indirectly
through the particular conventions of a language. For example, the words, “nomu” in Japanese, and, “drink” in English, are utterly unrelated to the actual act of imbibing. This difference is exactly why co-speech gesture is so interesting—it offers a direct visual complement to the conventional symbols of a language, and when combined with those symbols, provides a more complete “picture” of what a speaker means.
My research on the relationship between speech and gesture spans social, psychological, and neural levels. On the social and psychological levels, I use behavioral methods to demonstrate that gestures influence how children and adults comprehend language in different social contexts, and how they think during the explanation of difficult concepts. On the neural level, I use event-related potentials (ERPs) to show that gestures influence speech at multiple stages of language comprehension. See below for PDFs on these different topics.
My research and a paper
I co-authored with a Colgate student were cited in a BBC article
that focused on body movements and how they can help you learn. For a general background on gesture, see this article in Scientific American Mind
. For more on second-language learning and instruction, visit Colgate's Center for Language and Brain
If you are interested in more research on gesture, brain, and language, click here for a link to a special issue (June, 2007) on the topic in the journal, Brain and Language

) to learn more about the field of gesture research more broadly. For more on my work and the work of my collaborators, please visit my page on Research Gate

Using Electrical Signals to Measure Brain Activity
Event-related potentials (ERPs) are one of the cognitive neuroscience tools that I use in my lab. Check out this short video to learn how they work and what questions they can answer.
Language Learning and the Liberal Arts
Dr. Kelly is the co-director of Colgate's Center for Language and Brain
(CLB) which focuses on, among other things, issues involved in foreign language instruction and learning. Check out the video below to learn how the CLB promotes the psychological and social benefits of learning a foreign language at Colgate.
The 'Gate Way
In collaboration with Professors Yukari Hirata and Douglas Johnson, Dr. Kelly developed an easy-to-navigate online resource offering 13 tips to help students transition from high school to Colgate. LEARN MORE
