The Pupil Response and Individual Listening Load (PupILL): Towards the development of a clinically applicable measure of cognitive processing load in daily life hearing (WC2015-056)


Starting date: 01/09/2015

In today's ageing population, hearing loss is an increasing concern for public health and societal participation. Speech perception difficulties result in increased listening effort (cognitive processing load). This is associated with fatigue and increased sick leave from work. Recent research demonstrates that the pupil response is a senitive index of cognitive processing load during listening. The size of the pupil increases with increascognitive effort. This project focuses on enabling the applicain of pupillometry in the fied of Audiology.

We will assess which factors influence the pupil response and how the pupil response translates to daily-life situations. One of the factors that affect the pupil response is stress. The mechanism undelying the pupil rsponse is tightly intertwined with the physiological stress system, but this interaction has never been assessed in speech perception research.We hypothesize that more hearin difficulties in daily life are associated with higher cognitive processing load and larger stress responses during listening. In turn, these difficulties may affect phychosocial health (e.g., depression, loneliness, long-term stress).
