Purpose: When words are misperceived, listeners can rely on later context to repair an auditory perception, at the cost of increased effort. The current study examines whether effort a missing word in sentence is alleviated when listener has some advance knowledge what expect sentence. Method: Sixteen adults with hearing aids and 17 typical heard sentences that was followed by sufficient infer was. They repeated repaired. Sentences were preceded visual text screen showing either “XXXX” (unprimed) or priming previewing would be masked signal. Along intelligibility measures, pupillometry used as index listening over course each trial measure how influenced needed mentally word. Results: primed for need repaired upcoming sentence, reduced, indicated pupil size returning more quickly toward baseline after heard. Priming reduced lingering mental both groups. For group loss, also prevalence errors target other than suggesting preserves cognitive resources process whole Conclusion: These results suggest loss benefit from (advance cueing) during speech recognition, accurately less effortfully.

Purpose: A relevant aspect of listening is the effort required during speech processing, which can be assessed by pupillometry. Here, we pupil dilation response normal-hearing (NH) and hard hearing (HH) individuals to clear sentences masked or degraded sentences. We combined this assessment with functional magnetic resonance imaging (fMRI) investigate neural correlates response. Method: Seventeen NH participants ( M age = 46 years) were compared 17 HH 45 who individually matched in educational level. Participants repeated that presented clearly, distorted, masked. The sentence intelligibility level distorted was 50% correct. Silent baseline trials as well. Performance measures, responses, fMRI data acquired. Results: had overall poorer reception than participants, but not for noise-vocoded speech. In addition, an interaction effect observed smaller responses listeners conditions. Hearing impairment associated higher activation across conditions left superior temporal gyrus, silent baseline. However, region interest analysis indicated lower relative bilateral frontal regions insular cortex, listeners. also a weaker relation between right inferior gyrus. Overall, evoked Conclusion: Brain areas attentional cognitive-control processes may increasingly recruited when are related response, relationship Supplemental Material: https://doi.org/10.23641/asha.27162135

Comprehending speech in noise (SiN) poses a challenge for older hearing-impaired listeners, requiring auditory and working memory resources. Visual cues provide additional sensory information supporting understanding, while the extent of such visual benefit is characterized by large variability, which might be accounted individual differences capacity (WMC). In current study, we investigated behavioral neurofunctional (i.e., neural tracking) correlates audio-visual comprehension babble associations with WMC. Healthy adults hearing impairment quantified pure-tone loss (threshold average: 31.85–57 dB, N = 67) listened to sentences audio-only, visual-only modality performed pattern matching task, electroencephalography (EEG) was recorded. Behaviorally, no significant difference task performance observed across modalities. However, did find association between performance, suggesting more complex interplay cues, real-world listening tasks. Furthermore, found that presentation accompanied increased cortical tracking envelope, particularly right-hemispheric topographical cluster. Post-hoc, potential relationships but were not able establish association. Overall, our results show an increase associated congruent specifically right cluster, multisensory integration.
