Outcome measures
Primary outcome
This study*s main parameters are SRT scores and pupil diameter. We want to
investigate how these are affected by attentional engagement and hearing-loss.
Attentional engagement will be manipulated within subject and hearing-loss is a
between subject factor.
Secondary outcome
n.v.t.
Background summary
Listening to speech in a noisy environment is an effortful task in particular
for hearing impaired people. Attending to a persons face, voice, and his
relative location can improve speech reception in adverse listening conditions.
How these top-down attentional processes affect listening effort, a major cause
of fatigue in the hearing impaired, is unknown. We hypothesize that attending
to speech will lead to better comprehension and will result in a lower (i.e.
better) speech reception threshold. Additionally, attending to speech will
increase cognitive load, which results in a larger pupil response, an
indication of enhanced listening effort.
Study objective
The proposed studies will investigate the effect of auditory attention on
speech comprehension, its relation to listening effort, and the effect of
hearing loss on these processes.
Study design
In separate studies the effect of time, location, and talker-voice uncertainty
on listening effort by will be investigated. In case of time uncertainty, the
predictability of the onset of speech will be manipulated. Similarly the
predictability of location and talker will be investigated. Both normal hearing
and hearing-impaired individuals will participate in the experiments.
Additionally, possible interactions between these attentional processes will be
investigated.
Study burden and risks
This research is without any risk or burden for the participants. Participants
will perform one 1-2 hour session, which involves a number psychophysical tests
and the filling in of some questionnaires.
