Adriana Zekveld (PhD) and Hannah van Scheepen (junior researcher) perform the 2-year personal EMGO ReVanche project: “The Pupil Response and Individual Listening Load (PupILL): Towards the development of a clinically applicable measure of cognitive processing load in daily life hearing”.  This study is performed at the Section Ear & Hearing, Dept. of Otolaryngology-Head and Neck Surgery and EMGO Institute at the VU University medical centre in Amsterdam. The study focuses on the validation of pupillometric research to study processing load during listening.

Between 2011 and 2015, Adriana performed a VENI NWO project on the validation of pupillometry as a measure of cognitive processing load. In this study, pupillometry was innovatively combined with fMRI while participants with normal hearing or hearing loss performed speech perception tests.

Adriana co-supervises two PhD students, Barbara Ohlenforst and Yang Wang, in the context of a recently approved Marie Curie Initial Training Network EC project (LISTEN607373). The aim of the project is to further assess several aspects of the pupil response in relation to hearing and hearing loss. It is performed together with OTICON A/S, a leading hearing aid manufacturer. The main supervisor of this project is prof. Sophia Kramer, and we work closely together with dr. Graham Naylor and prof. Thomas Lunner (OTICON).

Adriana was also co-supervisor of Lisa Kilman, who assessed the influence of language on speech perception. Lisa is affiliated with the Linnaeus Centre HEAD, which is  is part of the Swedish Institute for Disability Research that builds on a collaboration between the Swedish universities of Linköping and Örebro. Lisa defended her PhD thesis in September 2015.

Research focus:

  • Physiological measures of cognitive processing during listening (pupillometry and fMRI)
  • Speech comprehension, hearing loss, age, listening effort & cognition
  • Cognitive hearing science
  • Cognitive test development (Text Reception Threshold test)
  • Evaluation of the speech perception benefit obtained from telephone-applications during speech comprehension
