Listening Effort Increases with Age

Listening Effort Increases with Age

July 15, 2011 In the News

Gosselin and Gagne (2011) evaluated self-reported "listening effort." Listening effort addresses "the attention and cognitive resources required to understand speech" and was based on two groups of adults listening to speech-in-noise. The younger group of adults had a mean age of 23.5  years, the older adults mean age was 69 years. A dual-task paradigm was used. The primary task involved a closed-set sentence recognition task, the secondary task involved a vibro-tactile pattern recognition task. Based on dual-task measures, Gosselin and Gagne determined that older adults expend more listening effort than younger adults (on these tasks) and older adults require more processing resources to understand the primary task (speech-in-noise), thereby leaving fewer (cognitive) resources available for the secondary (i.e., tactile) task.

The authors note that although subjective measures provide an indication of the subject's perceived level of ease or effort, subjective measures don't "appear  to reflect the availability of, or demand on, processing  resources." Specifically, when some people use an increased effort to understand speech-in-noise, they may not be aware of the additional  effort expended. Gosselin and Gagne note that although two individuals may perform the same on word recognition tasks, they may have expended very different levels of listening efforts to accomplish the same result.
