In this study we used The Office TV show as a stimulus in cochlear implant users. We showed that brain responses using this "naturalistic stimulus" relates to listening demand.
In this study we show that crossmodal plasticity is positively related to speech perception in noise in cochlear implant users.
Congrats to Bowen and Priyanka who have successfully defended thier MSC thesis': December 8, 2021
COVID-19 update: June 8, 2021
We have resumed all testing in the lab!
COVID-19 update: June 8, 2020
We have temporarily ceased all testing in the physical lab until further details are avalible. However, we have been busy developing online testing material. Stay tuned!
