Overview

The Sign Phonetics and Physiology Lab investigates the relationship between motor control
and the structure of signed languages. We use video and optical motion capture to study:

  • the phonetics of ASL
  • the relationship between sign phonetics and phonology
  • how signing is affected by adult neurogenic disorders, such as stroke, Parkinson’s
  • disease and traumatic brain injury
  • sign and gesture production in individuals with and without communication
    disorders
  • the physical realization of prosody in the sign modality

Facilities
The lab is equipped with a five-camera Optitrack motion capture system.

People
The lab is directed by Dr. Martha Tyrone. Students in the MS-SLP and HSLS PhD programs,
as well as students in other programs at Gallaudet, contribute to research in the lab.
