研究概览
简要总结
In this study, the investigators are testing whether cognitive training can lead to improvements in speech perception for individuals with hearing loss. Individuals will complete 20 hours of cognitive training that is designed to improve cognitive abilities such as short term memory and attention. The investigators predict that cognitive training that improves the cognitive abilities affected by hearing loss will improve speech perception.

结局指标
主要结局
Speech Perception in Noise Test - Improvement in speech perception accuracy from baseline to post-training for high and low predictability sentences
时间窗: Baseline, Weeks 2, 10, and 18
Sentences of high predictability and low predictability are played with multi-user talker babble. Participants must repeat the last word of each sentence as they heard it. The primary outcome measure will be the accuracy for repeating the sentence.
次要结局
- Working Memory Cognitive Training - Improvements in working memory abilities from baseline(Weeks 2, 10, and 18)
- Brain Performance Test(Weeks 2 and 10)
- Attention Cognitive Training - Improvements in attention abilities from baseline(Weeks 2, 10, and 18)
