Zekveld currently focuses on the application of pupillometry to assess listening effort during speech perception tasks. She is project manager of a Marie Curie ITN EC project (HEAR-ECO) that aims to develop and assess ecologically valid conditions for the evaluation of hearing-aid benefit using physiological measures including pupillometry. Furthermore, in 2020, a ZonMW project (REAL-HEARING) started which aims to assess the relationship between hearing loss and stress in daily life.
Zekveld recently performed a study to the relationships between listening effort and hearing-related stress: “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 was performed at the Section Ear & Hearing, Dept. of Otolaryngology-Head and Neck Surgery and Amsterdam Public Health research institute at the Amsterdam University Medical Centers, location VUmc, in Amsterdam. The study focused on the validation of pupillometric research to study processing load during listening.
Zekveld has innovatively combined pupillometry and functional Magnetic Resonance Imaging (fMRI) to assess the cognitive abilities that are reflected by the pupil response to listening (NWO Veni project). Internationally, her line of research has received much interest from research groups and industry. Key players in the field have adopted the method. These groups include one of the largest hearing aid manufacturers (OTICON A/S) that collaborate with Zekveld. Zekveld has co-supervises two PhD students (B Ohlenforst and Y Wang), and three more PhD students wil start in 2018.
Between 2009 and 2017, Zekveld has been working as a senior lecturer at the Linnaeus centre HEAD, Linköping University, Sweden. She assessed the contribution of semantic context on speech perception using behavioral methods, fMRI and pupillometry. She co-supervised Lisa Kilman (PhD, finished in 2015), who focused on the influence of language (Swedish versus English) on speech perception.
