Assessment of Listening Effort with Functional Near-Infrared Spectroscopy, in partnership with Seminars in Hearing

---

1.  Listening effort is thought to be determined by which factors? Task demands Hearing difficulties Listener's level of motivation All of the above

2.  What are some challenges in neuroimaging with hearing aids using EEG that may be overcome using fNIRS? Cap gets in the way of hearing instruments EEG gel may interfere with hearing instrument function Ferrous materials in hearing aids create artifact in recordings that may be hard to eliminate completely Time to prepare the client/participant can be quite long

3.  What are some challenges in neuroimaging with hearing instruments using fMRI that may be overcome or at least mitigated using fNIRS? Scanner noise Hearing aids are not permitted near scanner Motion artifacts All of the above

4.  Which of the following physiological measures can be assessed using fNIRS? Heart rate Oxygenated blood in cortical tissue De-oxygenated blood in cortical tissue All of the above

5.  In Rovetti at al. (2023), researchers observed that oxygenation in the prefrontal cortex was ___ when SNR was ___ and when context was ___. Higher, low, high Higher, low, low Lower, low, high Lower, low, low
