Auditory and Speech Perception Under Cognitive Load

Principal Investigators

About the project

Concurrent cognitive tasks form an integral part of everyday listening experience (e.g. monitoring road traffic while conversing with a passenger). Little is known about difficult listening conditions that do not alter the integrity of the signal, i.e. when there is no noisy background, but the listener struggles because s/he is concurrently engaged in another task (e.g. driving).

This type of adverse listening condition places demands on central cognitive resources and depletes resources available for listening. For older adults, listening is often already challenging due to age-related hearing loss. Further complicating the situation are those also suffering from age-related degenerative brain diseases (e.g. Alzheimer's); competing task demands alone could present tremendous difficulty due to limited cognitive resources.

This ongoing research project explores listening and speech comprehension under divided attention, concentrating on three population groups: normal-hearing older adults, hearing-impaired older adults, and normal-hearing young adults.
