简要总结
The objectives of the current project aim to determine whether a more controlled amplification method or a visual administration has an effect on hearing impaired older individuals' cognitive test scores.
详细描述
Aim 1 is to create a visually administered condition of a cognitive test and to validate this condition in comparison to the auditory administration. Data will be collected from younger individuals with normal hearing. Each younger individual is tested using both visual and auditory condition and the scores are compared across the two conditions. It is anticipated that the scores will not be significantly different between the two conditions.
Aim 2 is to examine the test condition effect on cognitive testing results in older individuals with hearing loss. The three test conditions include auditory unamplified, auditory amplified, and visual. Each older individual will be tested using two different test conditions. It is predicted the auditory amplified and visual administrations will alleviate the cognitive load associated with hearing difficulty and lead to improved performance on the test.

结局指标
主要结局
Cognitive Screening Results (Montreal Cognitive Assessment)
时间窗: The outcome measure was assessed immediately after the test. This applies to both conditions for all the arms.
The cognitive screening test of Montreal Cognitive Assessment (MoCA) was administered to 4 groups with different administration method conditions (see arms/groups table). MoCA is s standardized cognitive screening tool for mild cognitive impairment and dementia. The total score was used as outcome measure of this study and this score ranges from 0-30, with higher score being better performance.
次要结局
- Auditory Working Memory Performance(The outcome measure will be assessed immediately after the test.)
