Welcome to the SPACE Lab!

Directed by Dr. Alexander L. Francis, Ph.D., research in the SPACE Lab centers around the short- and long-term consequences of the cognitive challenges posed by both the presence of unwanted sound (noise) and difficulty with perceiving sound (hearing impairment). I employ psychophysiological and behavioral measures to investigate cognitive and affective responses to the challenges posed by environmental noise and loss of hearing acuity, especially in older adults. The central thesis of my work is that challenges to listening, whether due to unwanted sound or to difficulties assessing the auditory environment, increase demand on central processing mechanisms such as attention and working memory and induce negative affective responses with both short- and long-term impact on health and well-being. Results of my work will serve to better guide research and development of effective policy, workplace design, and clinical interventions for individuals with hearing impairment, unusual sensitivity to noise, and/or who work or live in noisy environments.
