Summary

This trial aims to understand how people with hearing loss experience extra effort when listening and how it affects their daily activities and social interactions. The researchers want to see how long this effort lasts and how using a

Who is the study for?
This trial is for individuals with hearing loss, specifically those who use cochlear implants and struggle with the extra effort required to listen. The study seeks participants who experience fatigue or mental strain from listening.
What is being tested?
The study focuses on how sentence manipulations can affect the listening effort of cochlear implant users. It aims to measure changes in effort during listening tasks and understand the impact of long-term cochlear implant use on this effort.
What are the potential side effects?
Since this trial involves non-medical interventions related to sentence manipulation, there are no direct medical side effects. However, participants may experience mental fatigue or stress during the listening tasks.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Cochlear implant participantsExperimental Treatment1 Intervention
Participants with cochlear implants. Speech recognition testing: Listening to and repeating speech in the free field in a sound-attenuated booth. We track percent-correct scores for whole sentences and words within each sentence. Changes in the participant's pupil size will be monitored by an Eyelink eye tracker placed 50 cm from the eyes. Phasic pupil dilations are linked with experiment timing landmarks interpreted as changes in listening effort.
Group II: Typical-hearing controlsActive Control1 Intervention
Typical-hearing controls. Speech recognition testing: Listening to and repeating speech in the free field in a sound-attenuated booth. We track percent-correct scores for whole sentences and words within each sentence. Changes in the participant's pupil size will be monitored by an Eyelink eye tracker placed 50 cm from the eyes. Phasic pupil dilations are linked with experiment timing landmarks interpreted as changes in listening effort.
