The Effects of Light Level and Signal-to-Noise Ratio on the Task-Evoked Pupil Response in a Speech-in-Noise Task

CONCLUSIONS: Brighter light conditions make TEPRs less sensitive to variations in listening effort across levels of SNR. Therefore, light level must be considered and reported in detail to ensure sensitivity of TEPRs and for comparisons of findings across different studies. It is recommended that TEPR testing be conducted in relatively low light conditions, considering both background illumination and screen luminance.SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.25676538.PMID:38690971 | DOI:10.1044/2024_JSLHR-23-00627
