Primary outcomePrimary: Visual Letter Monitoring Task — 8.48; 8.27; 8.07; 8.73 score on a scale
Summary
A double-blind randomised active-controlled trial aims to assess whether Cogmed (adaptive) working memory training results in improvements in untrained measures of cognition, speech perception and self-reported hearing abilities in older adults (50-74 years) with mild-moderate hearing loss who are existing hearing aid users, compared with an active placebo Cogmed (non-adaptive) control. It is hypothesised that improvements on trained Cogmed tasks, representing increased working memory capacity, will result in improved performance on cognitive and speech perception tasks that engage working memory. We also measure self-reported hearing ability to assess self-perceived benefit of Cogmed training.
