Abstract:
The aim of this study was to assess to what extent simultaneously-obtained measures of listening effort could be sensitive to auditory and cognitive manipulations in a speech perception task. The study also aimed to explore the possible relationship between RT and pupil dilation. A within-group design was adopted. Twenty-four normal-hearing adults, 20–41 years old, were recruited in the study. A significant effect of the SNR was found for all measures. RT, pupil dilation, and self-ratings can be obtained simultaneously when administering speech perception tasks, even though some limitations remain related to the absence of a retention period after the listening phase. The sensitivity of the three measures to changes in the auditory environment differs. RTs and self-ratings proved most sensitive to changes in SNR.
