Preserved communication abilities promote healthy ageing. To this end, the age-typical loss of sensory acuity might in part be compensated for by an individual’s preserved attentional neural filtering. Is such a compensatory brain–behaviour link longitudinally stable? Can it predict individual change listening behaviour? We here show that behaviour and filtering ability follow largely independent developmental trajectories modelling electroencephalographic behavioural data N = 105 ageing individuals (39–82 y). First, despite expected decline hearing-threshold-derived acuity, listening-task performance proved stable over 2 y. Second, were correlated only within each separate measurement timepoint (T1, T2). Longitudinally, however, our results raise caution on attention-guided metrics as predictors behaviour: neither at T1 nor its 2-year could change, under combination strategies.

Abstract Observing lip movements of a speaker is known to facilitate speech understanding, especially in challenging listening situations. Converging evidence from neuroscientific studies shows enhanced processing audiovisual stimuli. However, the interindividual variability this visual benefit and its consequences on behavior are unknown. Here, we analyzed source-localized magnetoencephalographic (MEG) responses normal-hearing participants with or without an additional distractor speaker. Using temporal response functions (TRFs), show that neural are, general, when challenging. After conducting crucial control for acoustics, effectively contribute higher tracking, particularly present. extent varied greatly among participants. Probing behavioral relevance, individuals who more movement information terms stronger drop performance increase perceived difficulty mouth occluded by surgical face mask. By contrast, no effect was found not occluded. We provide novel insights how tracking varies individuals. Furthermore, reveal relevance demonstrating negative absent. Our results also offer potential implications future objective assessments perception.

They listened to in-house–designed matrix-style sentences that either provided supportive context or random, we recorded their electroencephalography. Neurophysiological responses analyzed through auditory evoked potentials tracking at different linguistic timescales (i.e., phrase, word, syllable phoneme rate) phase-locking values. The results showed was associated with decreased response accuracy recognition task. significantly impacted P2 component potentials, influenced word rates, but not phrase rates.

Age-related sensory declines are unavoidable and closely linked to decreased visual, auditory, cognitive functions. However, the interrelations of these remain poorly understood. Despite extensive studies in each domain, shared age-related characteristics complex may not consistently manifest direct relationships at individual level. We investigated link between visual auditory perceptual healthy aging their relation function using six psychophysical three tasks.

When individuals listen to speech, their neural activity phase-locks the slow temporal rhythm, which is commonly referred as "neural tracking". The tracking mechanism allows for detection of an attended sound source in a multi-talker situation by decoding signals obtained electroencephalography (EEG), known auditory attention (AAD). Neural with AAD can be utilized objective measurement tool diverse clinical contexts, and it has potential applied neuro-steered hearing devices.

Cortical tracking of speech is vital for segmentation and linked to intelligibility. However, there no clear consensus as whether reduced intelligibility leads a decrease or an increase in cortical tracking, warranting further investigation the factors influencing this relationship. One such factor listening effort, defined cognitive resources necessary comprehension, reported have strong negative correlation with Yet, studies examined relationship between intelligibility, speech.

Abstract The cortical tracking of stimulus features (such as the sound envelope) is a crucial neural requisite how we process continuous music. We here tested whether beat, typically related to rhythm processing, modulated by pitch predictability and other top-down factors. Participants listened tonal (high predictability) atonal (low music while undergoing EEG, analysed their acoustic envelope. Interestingly, envelope was stronger listening than music, likely reflecting listeners’ violated expectations. Envelope also with more expertise enjoyment. Furthermore, surprisal (using IDyOM) show that expectations for match those computed IDyOM model, higher (prediction errors) Behaviourally, measured participants’ ability tap along beat sequences in two experiments. In both experiments, finger-tapping performance better condition, indicating positive effect on behavioural processing.
