Within aMCI, no significant correlations were observed between CR and brain volumes. Positive correlations with CR were observed in language, attention, and visual learning in both aMCI and naMCI groups. The current study adds to the minimal literature on CR and naMCI.

The aim of this study was to investigate the role of HL on covert orienting of attention, selective attention and executive control. We compared older adults with and without mild to moderate hearing loss (26-60 dB) performing (1) a spatial cueing task with uninformative central cues (social vs. nonsocial cues), (2) a flanker task and (3) a neuropsychological assessment of attention. The results showed that overall response times and flanker interference effects were comparable across groups. However, in spatial cueing of attention using social and nonsocial cues, hearing impaired individuals were characterized by reduced validity effects, though no additional group differences were found between social and nonsocial cues. Hearing impaired individuals also demonstrated diminished performance on the Montreal Cognitive Assessment (MoCA) and on tasks requiring divided attention and flexibility. This work indicates that while response speed and response inhibition appear to be preserved following mild-to-moderate acquired hearing loss, orienting of attention, divided attention and the ability to flexibly allocate attentional resources are more deteriorated in older adults with HL.
