“…Objective measures like P300 ERPs may thus be appropriate to supplement studies involving cognitive performance assessments. N2 and P3 latencies are related to stimulus evaluation processes such as encoding and classification (Giroud, Lemke, Reich, Matthes, & Meyer, ; Ozdemir, Demiroren, Demir, & Serin, ; Santos Filha & Matas, ). In this study, there was a significant difference in N2 and P3 latencies between the two tinnitus subgroups, further illustrating that cognitive deficits might be characteristic of tinnitus.…”

IntroductionSubjective chronic tinnitus is a common medical syndrome with a high frequency of cognitive impairment; however, the characteristics of cognitive impairment in chronic tinnitus are poorly understood. Investigating the scope of cognitive impairment across the severity spectrum of tinnitus patients may shed light on the issue.MethodsA consecutive series of 207 subjective chronic tinnitus patients were classified into mild tinnitus group (n = 95) and severe tinnitus group (n = 112) by THI score (the cutoff THI scores were 37/38). These patients were assessed using the Cognitive Abilities Screening Instrument (CASI) and P300 event‐related potential.ResultsAlthough pure tone averages were not different between mild or severe tinnitus patients, severe tinnitus patients scored lower on the CASI assessment as well as almost all subdomains of CASI, particularly in items such as “short‐term memory,” “concentration or mental manipulation,” “orientation,” “abstraction and judgment,” “language abilities,” and “visual construction.” Furthermore, compared to mild tinnitus patients, severe tinnitus patients exhibited longer N2 and P3 latencies. Finally, a correlation analysis revealed that tinnitus severity was negatively correlated with CASI score and positively correlated with N2 and P3 latencies.ConclusionsThis study reveals that tinnitus patients on the severe end of the spectrum may be at risk for serious cognitive deficits, which may not be a secondary response to disease manifestations but a primary feature of the underlying disease.

“…Only correctly identified deviants were averaged, resulting in a maximum of 60 trials per deviant and 540 trials for the standard stimulus. This experimental procedure had already been tested in a previous study (Giroud et al ., ).…”

“…The nonsense syllables (logatomes) asa (/′a:sa/), ascha (/′a:ʃa/), and afa (/’a:fa/) from the phoneme perception test (Boretzki et al ., ; Schmitt et al ., ) were used in our study. This stimulus material had been established previously in other studies using EEG (Giroud et al ., ,b). The logatomes /′a:ʃa/ and /′a:sa/, /’a:fa/ and /′a:sa/, and /′a:ʃa/ and /’a:fa/, respectively, were morphed together to create two equidistant intermediate stimuli (Zorn, ).…”

“…It is likely that these benefits in cognitive‐related auditory tasks result from a facilitation of perceptual auditory processes during the use of hearing aids. Furthermore, it is of the utmost importance to study the extent to which these cognitive resources can be supported by training in normal hearing adults, as already suggested in a previous paper (Giroud et al ., ). To this end, we compared normal hearing older adults to a middle‐aged control group during spectral speech processing in a repeated measurement design that allowed for the evaluation of longitudinal changes in auditory neurocognitive processing as a function of repeated auditory exposure.…”

“…We expected to find better behavioral performance (higher ACC and lower RT) for deviants with stronger acoustic deviation to the standard stimulus than lower acoustic deviation (Johnson, ; Kok, ; Katayama & Polich, ; Gaál et al ., ; Giroud et al ., ,b). Furthermore, we expected the better behavioral detection of the deviant with strong acoustic deviation to be reflected in higher mean GFP and shorter onsets of the N2b and P3b components (Johnson, ; Kok, ; Katayama & Polich, ; Gaál et al ., ; Giroud et al ., ,b). We also hypothesized that older adults would evoke lower N2b and P3b mean GFPs and shorter onsets, as has been found in previous studies which compared older and younger adults (Schiff et al ., ; Juckel et al ., ).…”

Cognitive abilities such as attention or working memory can support older adults during speech perception. However, cognitive abilities as well as speech perception decline with age, leading to the expenditure of effort during speech processing. This longitudinal study therefore investigated age-related differences in electrophysiological processes during speech discrimination and assessed the extent of enhancement to such cognitive auditory processes through repeated auditory exposure. For that purpose, accuracy and reaction time were compared between 13 older adults (62-76 years) and 15 middle-aged (28-52 years) controls in an active oddball paradigm which was administered at three consecutive measurement time points at an interval of 2 wk, while EEG was recorded. As a standard stimulus, the nonsense syllable / 0 a:Sa/was used, while the nonsense syllable / 0 a:sa/ and a morphing between / 0 a:Sa/ and / 0 a:sa/ served as deviants. N2b and P3b ERP responses were evaluated as a function of age, deviant, and measurement time point using a data-driven topographical microstate analysis. From middle age to old age, age-related decline in attentive perception (as reflected in the N2b-related microstates) and in memory updating and attentional processes (as reflected in the P3b-related microstates) was found, as indicated by both lower neural responses and later onsets of the respective cortical networks, and in age-related changes in frontal activation during attentional stimulus processing. Importantly, N2b-and P3b-related microstates changed as a function of repeated stimulus exposure in both groups. This research therefore suggests that experience with auditory stimuli can support auditory neurocognitive processes in normal hearing adults into advanced age.

Speech understanding in noisy situations is compromised in old age. This study investigated the energetic and informational masking components of multi‐talker babble noise and their influence on neural tracking of the speech envelope in a sample of healthy older adults. Twenty‐three older adults (age range 65–80 years) listened to an audiobook embedded in noise while their electroencephalogram (EEG) was recorded. Energetic masking was manipulated by varying the signal‐to‐noise ratio (SNR) between target speech and background talkers and informational masking was manipulated by varying the number of background talkers. Neural envelope tracking was measured by calculating temporal response functions (TRFs) between speech envelope and EEG. Number of background talkers, but not SNR modulated the amplitude of an earlier (around 50 ms time lag) and a later (around 300 ms time lag) peak in the TRFs. Selective attention, but not working memory or peripheral hearing additionally modulated the amplitude of the later TRF peak. Finally, amplitude of the later TRF peak was positively related to accuracy in the comprehension task. The results suggest that stronger envelope tracking is beneficial for speech‐in‐noise understanding and that selective attention is an important ability supporting speech‐in‐noise understanding in multi‐talker scenes.
