“…While reduced sound sensitivity is the primary limiter of speech intelligibility, especially in older listeners ( Humes et al., 2020 ; Humes and Dubno, 2010 ), successful cocktail-party listening requires more than just correctly identifying phonemes—it also requires auditory object formation ( Shinn-Cunningham, 2008 ), which relies on a successful interplay between myriad peripheral, central, and cognitive processes, whose age-related declines may not be coupled with ARSHL ( Gordon-Salant et al., 2020 ). Thus, the genes that influence cocktail-party listening are not necessarily the same as those influencing ARSHL.…”

“…In healthy ageing subjects, speech-in-noise processing appears to be associated with increased recruitment of a more diffuse cortical network (Eckert et al, 2008;Kuchinsky & Vaden, 2020;Wong et al, 2009). This finding suggests that age-related alterations of peripheral and central auditory processing lead to a compensatory shift in the reliance on cognitive operations to support successful speech perception in challenging listening conditions (Gordon-Salant et al, 2020). Only a small number of studies has specifically evaluated alpha power in older subjects during speech perception in degraded listening conditions.…”

Parkinson's disease (PD) has increasingly been associated with auditory dysfunction, including alterations regarding the control of auditory information processing. Although these alterations may interfere with the processing of speech in degraded listening conditions, behavioural studies have generally found preserved speech-in-noise recognition in PD. However, behavioural speech audiometry does not capture the neurophysiological mechanisms supporting speech-in-noise processing. Therefore, the aim of this study was to investigate the neural oscillatory mechanisms associated with speech-in-noise processing in PD. Twelve persons with PD and 12 age-and gender-matched healthy controls (HCs) were included in this study. Persons with PD were studied in the medication off condition. All subjects underwent an audiometric screening and performed a sentence-in-noise recognition task under simultaneous electroencephalography (EEG) recording. Behavioural speech recognition scores and self-reported ratings of effort, performance, and motivation were collected. Time-frequency analysis of EEG data revealed no significant difference between persons with PD and HCs regarding delta-theta (2-8 Hz) inter-trial phase coherence to noise and sentence onset. In contrast, significantly increased alpha (8-12 Hz) power was found in persons with PD compared with HCs during the sentence-in-noise recognition task. Behaviourally, persons with PD demonstrated significantly decreased speech recognition scores, whereas no significant differences were found regarding effort, performance, and motivation ratings. These results suggest that persons with PD allocate more cognitive resources to support speech-in-noise processing. The interpretation of this finding is discussed in the context of a top-down mediated compensation mechanism for inefficient filtering and degradation of auditory input in PD.

“…Moreover, the perception of English speech under noisy conditions occupied many more cognitive resources, including WM and inhibitory ability ( 84 ). After all, having controlled for language skills, WM, and emotional intelligence, the better inhibitory ability still predicted higher problem-solving accuracy ( 85 ).…”

Semantics–Prosody Stroop Effect on English Emotion Word Processing in Chinese College Students With Trait Depression

et al. 2022

This study explored the performance of Chinese college students with different severity of trait depression to process English emotional speech under a complete semantics–prosody Stroop effect paradigm in quiet and noisy conditions. A total of 24 college students with high-trait depression and 24 students with low-trait depression participated in this study. They were required to selectively attend to either the prosodic emotion (happy, sad) or semantic valence (positive and negative) of the English words they heard and then respond quickly. Both prosody task and semantic task were performed in quiet and noisy listening conditions. Results showed that the high-trait group reacted slower than the low-trait group in the prosody task due to their bluntness and insensitivity toward emotional processing. Besides, both groups reacted faster under the consistent situation, showing a clear congruency-induced facilitation effect and the wide existence of the Stroop effect in both tasks. Only the Stroop effect played a bigger role during emotional prosody identification in quiet condition, and the noise eliminated such an effect. For the sake of experimental design, both groups spent less time on the prosody task than the semantic task regardless of consistency in all listening conditions, indicating the friendliness of basic emotion identification and the difficulty for second language learners in face of semantic judgment. These findings suggest the unneglectable effects of college students’ mood conditions and noise outside on emotion word processing.
