“…The deviance-related increase in response times with audiovisual information compared to still faces or unspecific lip movement was more pronounced in older than in younger adults, suggesting that they suffered more from the sudden switch in target talker location than the younger group. In line with this, previous research has shown that older adults experience higher conflict costs in multi-talker scenarios, resulting in less accurate responses, when the attentional load is high (Passow et al, 2012), and higher response times following distraction due to unpredictable sound modulations (Volosin et al, 2017) or deviant target positions (Getzmann et al, 2015).…”

In natural conversations, visible mouth and lip movements play an important role in speech comprehension. There is evidence that visual speech information improves speech comprehension, especially for older adults and under difficult listening conditions. However, the neurocognitive basis is still poorly understood. The present EEG experiment investigated the benefits of audiovisual speech in a dynamic cocktail-party scenario with 22 (aged 20 to 34 years) younger and 20 (aged 55 to 74 years) older participants. We presented three simultaneously talking faces with a varying amount of visual speech input (still faces, visually unspecific and audiovisually congruent). In a two-alternative forced-choice task, participants had to discriminate target words ("yes" or "no") among two distractors (one-digit number words). In half of the experimental blocks, the target was always presented from a central position, in the other half, occasional switches to a lateral position could occur. We investigated behavioral and electrophysiological modulations due to age, location switches and the content of visual information, analyzing response times and accuracy as well as the P1, N1, P2, N2 event-related potentials (ERPs) and the contingent negative variation (CNV) in the EEG. We found that audiovisually congruent speech information improved performance and modulated ERP amplitudes in both age groups, suggesting enhanced preparation and integration of the subsequent auditory input. However, these benefits were only observed as long as no location switches occurred. To conclude, meaningful visual information in a multi-talker setting, when presented from the expected location, is shown to be beneficial for both younger and older adults.

“…When irregular spatial shifts of the target occur, older adults are even more affected by distractors than younger people (Volosin, Gaál, & Horváth, 2017) and need longer phases of (re-)orientation toward the relevant stimulus (Correa-Jaraba, Cid-Fernández, Lindín, & Díaz, 2016;Getzmann, Falkenstein, & Wascher, 2015).…”

When background auditory events lead to enhanced auditory event-related potentials (ERPs) for closely following sounds, this is generally interpreted as a transient increase in the responsiveness of the auditory system. We measured ERPs elicited by irrelevant probes (gaps in a continuous tone) at several time-points following rare auditory events (pitch glides) in younger and older adults, who watched movies during stimulation. Fitting previous results, in younger adults, gaps elicited increasing N1 auditory ERPs with decreasing glide-gap separation. N1 increase was paralleled by an ERP decrease in the P2 interval. In older adults, only a glide-gap separation dependent P2 decrease, but no N1-effect was observable. This ERP pattern was likely caused by a fronto-central negative waveform, which was delayed in the older adult group, thus overlapping N1 and P2 in the younger, but overlapping only P2 in the older adult group. Because the waveform exhibited a polarity reversal at the mastoids, it was identified as a mismatch negativity (MMN). This interpretation also fits previous studies showing that gap-related MMN is delayed in older adults, reflecting an age-related deterioration of fine temporal auditory resolution. These results provide a plausible alternative explanation for the ERP enhancement for sounds following background auditory events.

“…amplitude enhancement with growing age) is consistent for P1 across studies, for N1, and especially P2, consistency decreases, with more counter-examples showing reductions with growing age. It is also important to note that the ERP waveform elicited by other transient events, for example by short gaps in continuous tones shows the opposite pattern as a function of age: gap-related N1 and P2 are markedly reduced in older adults in comparison to younger adults (Harris et al, 2012;Volosin et al, 2017).…”

This is the accepted version of Horváth, J., Gaál, Z. A., & Volosin, M. (2017). Sound offset-related brain potentials show retained sensory processing, but increased cognitive control activity in older adults. Neurobiology of Aging, 57,[232][233][234][235][236][237][238][239][240][241][242][243][244][245][246] AbstractIt has been hypothesized that age-related hearing loss is caused not only by peripheral, but also central changes in the auditory system. Many studies utilized event-related potentials (ERPs) elicited by sound onsets to characterize age-related differences in central auditory processing. Age-related ERP enhancements in such studies have often been interpreted in terms of elevated sensitivity to auditory stimulation. Such ERPs, however, comprise various components reflecting different aspects of auditory and task-related processing. The composition of the waveforms may considerably differ for ERPs elicited by other auditory events. In the present study ERPs elicited by tone-offsets were used to characterize processing differences between younger and older adults in a short-go, tone-duration discrimination paradigm. Whereas the onset-related auditory ERP was enhanced in the older adult group, no age-related differences were found in the offset-related auditory ERPs observable at temporal electrodes. In older adults, however, offset-related processing was dominated by an N2 that could reflect enhanced cognitive control activities. Because N2 was present regardless discrimination difficulty, younger adults may have framed the task as offset-detection, whereas older adults represented the task as "genuine" discrimination.
