Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Auditory Amplified-Visual
This arm is designed to test the contrast between auditory amplified and visual conditions.
Auditory amplified
The cognitive test will be administered using a computer-based signal processing to amplify the instruction. The presentation level is customized to the individual's hearing thresholds.
Visual
The cognitive test will be administered visually by using timed computer slides.
Auditory Amplified-Unamplified
This arm is designed to test the contrast between auditory amplified and unamplified conditions.
Auditory amplified
The cognitive test will be administered using a computer-based signal processing to amplify the instruction. The presentation level is customized to the individual's hearing thresholds.
Auditory unamplified
The cognitive test will be administered by using a generic presentation level that simulates a normal conversational level.
Auditory Unamplified-Visual
This arm is designed to test the contrast between auditory unamplified and visual conditions.
Visual
The cognitive test will be administered visually by using timed computer slides.
Auditory unamplified
The cognitive test will be administered by using a generic presentation level that simulates a normal conversational level.
Younger control group
This arm is designed to validate the visual version by comparing to the auditory version in a group of younger normal hearing controls.
Visual
The cognitive test will be administered visually by using timed computer slides.
Auditory unamplified
The cognitive test will be administered by using a generic presentation level that simulates a normal conversational level.
