Research In Profile

When speech is masked or degraded in some way, demands are placed on cognitive processes beyond those needed for comprehension of clear speech. Such recruitment is probably why listening in noise “feels” effortful, even when intelligibility is high. Increased effort is aversive and tiring, and the goal of making listening less effortful is increasingly recognized as important. Researchers in my group study how individual cognitive differences and experiential factors contribute both to the experience of listening effort, and to the demand placed on cognition to help understand speech in challenging listening environments.
