“…Demands on short-term memory likely exacerbate the age confound between our NH and CI listeners. Future work could consider using fewer keywords and providing age-matched controls to this task (Cleary et al, 2018).…”

There are an increasing number of bilateral and single-sided-deafness cochlear-implant (CI) users who hope to achieve improved spatial-hearing abilities through access to sound in both ears. It is, however, unclear how speech is processed when inputs are functionally asymmetrical, which may have an impact on spatial-hearing abilities. Therefore, functionally asymmetrical hearing was controlled and parametrically manipulated using a channel vocoder as a CI simulation. In Experiment 1, normal-hearing (NH) listeners performed a dichotic listening task (i.e., selective attention to one ear, ignoring the other) using asymmetrical signal degradation. Spectral resolution varied independently in each ear (4, 8, 16 channels, and unprocessed control). Performance decreased with decreasing resolution in the target ear and increasing resolution in the interferer ear. In Experiment 2, these results were replicated using a divided attention task (attend to both ears, report one after sentence completion) in both NH and bilateral CI listeners, although overall performance was lower than in Experiment 1. In Experiment 3, frequency-to-place mismatch simulated shallow CI insertion depths (0, 3, 6-mm shifts, and unprocessed control). Performance mostly decreased with increasing shift in the target ear and decreasing shift in the interferer ear; however, performance nonmonotonicities occurred. The worst performance occurred when the shift matched across ears, suggesting that pitch similarity increases difficulty. The results show that it is more difficult to attend an ear that is relatively degraded or distorted, which may set spatial-hearing limitations for CI users when trying to attend to a target in complex auditory scenes.

“…Four studies used digit span tasks to compare auditory working memory in which participants hear and recall a sequence of digits; the length of sequences increase as participants recall them correctly. Performances for CI users were reduced in Tao et al (2014) and Hamdy et al (2023) but similar between groups in Moberly et al (2017a) and Cleary et al (2018). The latter is possibly a result of each sequence length being presented twice allowing participants a chance to perform better on each sequence and therefore, resulting in no significant differences.…”

“…Direct comparisons between the current findings and previous literature are difficult because very few studies have directly compared CI users and TH listeners in auditory memory tasks and those that have, yielded inconsistent results. Moberly et al (2017a) and Cleary et al (2018) compared CI users and TH listeners on an auditory digit span test and showed no group differences for either forward or reverse digit spans. However, Tao et al (2014) compared CI users and TH listeners on a digit span test and found that only reverse digit span scores were lower in CI users compared to TH controls while forward digit span were comparable across groups.…”

IntroductionA common concern for individuals with moderate-to-profound hearing loss who have received a cochlear implants (CIs) is difficulty following conversations in noisy environments. A possible reason is the increased use of cognitive resources (attention and working memory) to disambiguate the speech stimuli potentially causing detriments in functional aspects of life. However, this relationship is not well-documented. The overall arching goal of this study was to quantify the relationships between Patient-Reported Outcome Measures (PROMs) and cognitive ability through working memory and speech perception measures.MethodsIn the current study, 31 adult CI users and typical hearing (TH) age-matched controls were recruited. CI users completed PROMs including Speech, Spatial and Quality of hearing survey (SSQ) and versions of a quality of life (QOL) for CI users (CIQOL) and Nijmegen Cochlear Implant Questionnaire (NCIQ). Measures of cognition were assessed using internet-based tools. Outcomes were compared between groups and PROMs and were related to the cognitive tasks.ResultsReduced auditory working memory and speech perception in noise were observed in CI users compared to TH controls. Correlation analyses revealed significant domain-specific PROM relationships with cognitive tasks in CI users, but not in TH controls. The SSQ had more significant relationships compared to the other PROMS.ConclusionThese results suggest that internet-based metrics of cognitive ability are associated with the functional hearing aspects of life in CI users and that SSQ is more sensitive to investigate the cognitive related effects of QOL compared to other commonly used PROMs.
