Mood shapes the impact of reward on perceived fatigue from listening.

Knowledge of the underlying mechanisms of effortful listening could help to reduce cases of social withdrawal and mitigate fatigue, especially in older adults. However, the relationship between transient effort and longer term fatigue is likely to be more complex than originally thought. Here, we manipulated the presence/absence of monetary reward to examine the role of motivation and mood state in governing changes in perceived effort and fatigue from listening.

Sensory-Processing Sensitivity Predicts Fatigue From Listening, But Not Perceived Effort, in Young and Older Adults.

Purpose: Listening-related fatigue is a potential negative consequence of challenges experienced during everyday listening and may disproportionately affect older adults. Contrary to expectation, we recently found that increased reports of listening-related fatigue were associated with better performance on a dichotic listening task. However, this link was found only in individuals who reported heightened sensitivity to a variety of physical, social, and emotional stimuli (i.

The time-course of linguistic interference during native and non-native speech-in-speech listening.

Recognizing speech in a noisy background is harder when the background is time-forward than for time-reversed speech, a masker direction effect, and harder when the masker is in a known rather than an unknown language, indicating linguistic interference. We examined the masker direction effect when the masker was a known vs unknown language and calculated performance over 50 trials to assess differential masker adaptation. In experiment 1, native English listeners transcribing English sentences showed a larger masker direction effect with English than Mandarin maskers.

Predictors of Listening-Related Fatigue Across the Adult Life Span.

Listening-related fatigue is a potentially serious negative consequence of an aging auditory and cognitive system. However, the impact of age on listening-related fatigue and the factors underpinning any such effect remain unexplored. Using data from a large sample of adults ( = 281), we conducted a conditional process analysis to examine potential mediators and moderators of age-related changes in listening-related fatigue.

Older adults show a more sustained pattern of effortful listening than young adults.

Listening to speech in adverse conditions can be challenging and effortful, especially for older adults. This study examined age-related differences in effortful listening by recording changes in the task-evoked pupil response (TEPR; a physiological marker of listening effort) both at the level of sentence processing and over the entire course of a listening task. A total of 65 (32 young adults, 33 older adults) participants performed a speech recognition task in the presence of a competing talker, while moment-to-moment changes in pupil size were continuously monitored.
