Continuous tracking of effort and confidence while listening to speech-in-noise in young and older adults
Reporting discomfort when noise affects listening experience suggests that listeners may be aware, at least to some extent, of adverse environmental conditions and their impact on listening experience. This involves monitoring internal states (effort and confidence). Here we quantified continuous self-report indices that track one’s own internal states and investigated age-related differences in this ability. We instructed two groups of young and older adults to continuously report their confidence and effort while listening to stories in fluctuating noise. Using cross-correlation analyses between the time series of fluctuating noise and those of perceived effort or confidence, we showed that (1) participants modified their assessment of effort and confidence based on variations in the noise, with a 4 s lag; (2) there were no differences between the groups. These findings imply extending this method to other areas, expanding the definition of metacognition, and highlighting the value of this ability for older adults.
期刊介绍:
Consciousness and Cognition: An International Journal provides a forum for a natural-science approach to the issues of consciousness, voluntary control, and self. The journal features empirical research (in the form of regular articles and short reports) and theoretical articles. Integrative theoretical and critical literature reviews, and tutorial reviews are also published. The journal aims to be both scientifically rigorous and open to novel contributions.
