Abstract
BackgroundGrowing evidence suggests changes in cognitive control in persons with age-related hearing loss (ARHL); however, the nature of these alterations especially in those with mild ARHL needs further investigation. MethodsThis study examined group differences in cognitive control between 20 older adults with unaided mild ARHL and 20 age- and education-matched normal hearing (NH) controls using inhibitory control and value-directed strategic attention tasks. Additionally, the association between inhibitory control and strategic attention was evaluated. A visual Go/No-Go task and a value-directed word list learning task were used to examine inhibitory control and value-directed strategic attention, respectively. ResultsData analysis revealed that the persons with mild ARHL performed worse on both tasks relative to NH controls, suggesting poorer inhibitory control and lower value-directed strategic attention. Additionally, poorer inhibitory control was associated with worse strategic attention even when demographic variables, cognitive screening score, and hearing ability were controlled. ConclusionsOur findings contribute to the body of literature on modality-independent changes in cognitive control in persons with mild ARHL and advance our knowledge of the links between cognitive control processes.
