Interventions

  • sentence manipulations — BEHAVIORAL
    Auditory stimuli (sentences) are manipulated to have key words masked by noise, or to have prosody (pitch contour) manipulated to be consistent or inconsistent with a specific inferred meaning. Participants repeat the sentences while a camera tracks changes in their eye movements and changes in pupil dilation.

Study Details

People with hearing loss experience extra effort when listening, which can lead to severe psychological barriers to communication and social participation. Listening effort can lead to fatigue, mental strain, burnout, medical sick leave, and the need for increased time to recover from regular daily activities. This proposal aims to understand effort changes on a moment-to-moment basis during listening, how long the effort lasts, and how the planning and execution of effort is impacted by the experience of using a cochlear implant.

Arms

  • Experimental: Cochlear implant participants
    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.
  • Active Comparator: Typical-hearing controls
    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.
