Welcome to the Speech Perception and Cognitive Effort (SPACE) Lab!
Directed by Dr. Alexander L. Francis, Ph.D., research in the SPACE Lab investigates the contribution of cognitive mechanisms such as working memory and selective attention to understanding speech in difficult circumstances, such as when listening to a talker with an unfamiliar accent or in the presence of competing sounds or other background noise. We use behavioral and psychophysiological measures to assess speech understanding, cognitive effort and stress in younger and older adults with and without hearing impairment under a range of listening conditions. Results of this research provide insight into the cognitive foundations of spoken language understanding, and will contribute to research on improving workplace policies and design, particularly as related to better accommodating the needs of older workers and those with hearing impairment.
