Speech Perception In Noise

Background and Aim: Because speech percep­tion is disturbed in people who are exposed to noise, this study aimed to investigate the effect of work environment noise on working memory capacity, temporal, and dichotic auditory proce­ssing and relationship between them in elemen­tary school teachers. Methods: Fifty-six female aged 30−50 years were enrolled in our study case and control groups. A total of 28 teachers with normal hearing and poor speech perception in noise were in the case group, and 28 women were controls with normal hearing and good scores in speech perception in noise who did not work in a noisy environment. Working memory tests, dichotic digit test (DDT) and gap-detection test (GDT) were performed for both groups. The mean score of each test was obtained from the two groups and the results were analyzed. Results: Comparison of means between the two groups in DDT, GDT, and working memory capacity test showed that the scores of the case group were significantly lower than those in the control group (p < 0.05). There was no correla­tion between working memory capacity test, DDT, and GDT scores. (p > 0.05, r < 0.1). Conclusion: Noise exposure in the work envi­ronment causes weakness in temporal and dich­otic auditory processing, and working memory capacity. But there was no correlation between working memory capacity and auditory proce­ssing. The findings of this study show the eff­ects of noise exposure on speech perception and the need to protect hearing from noise.

Standardized Test Performance

Stereotype threat (ST) occurs when individuals primed with negative stereotypes underperform relative to a control group. The current work considers individual differences in ST effects on real world measures like standardized test performance (SDTP). Working Memory Capacity (WMC) is investigated as a mediator and/or moderator of ST for race/ethnicity. Findings revealed a lack of strong evidence for the effect of ST. However, we demonstrated that trait WMC moderates ST for race such that higher WMC is associated with higher scores on standardized tests under conditions of race related ST. For future work on ST, we consider replication issues as well as the importance of WMC for performance under ST including how WMC and SDTP have been shown to improve through implementing self-regulation and mindfulness.

Variable Environment

Visual working memory (VWM) is the ability to actively maintain visual information over short periods of time and is strongly related to global fluid intelligence and overall cognitive ability. In our study, we used two indices of visual working memory capacity: the behavioral estimate of capacity (K) and contralateral delay activity (CDA) in order to check whether training in a Real-Time Strategy (RTS) video game StarCraft II can influence the VWM capacity measured by the change detection task. We also asked a question whether individual differences in behavioral and psychophysiological indices of VWM can predict the effectiveness of video game training. Sixty-two participants (non-players) were recruited to the experiment. Participants were randomly assigned to either experimental (Variable environment), active control (Fixed environment), and passive control groups. Experimental and active control groups differed in the type of training received. Training consisted of 30 h of playing the StarCraft II game. Participants took part in two EEG sessions (pre- and post-training) during which they performed the VWM task. Our results showed that working memory capacity (K calculated according to Pashler’s formula) increases after training in both experimental groups, but not in a control group. We have also found a correlation between average visual working memory capacity (calculated as K) and mean CDA amplitude no matter which group we are looking at. And, last but not least, we have found that we can predict the amount of improvement in the RTS video game by looking at the psychophysiological indices (CDA amplitude) recorded at baseline (before training), but only in the experimental group. We think that the strength of the psychophysiological indicator of VWM capacity might be a marker of the future success in video game acquisition.

AbstractStudies have examined listening effort in individuals with hearing loss to determine the extent of the impairment. Regarding cochlear implants (CIs), results suggest that listening effort is improved using bilateral CIs compared to unilateral CIs. Few studies have investigated listening effort and outcomes related to the hybrid CI.Here, we compared listening effort across three CI groups, and to a normal-hearing control group. The impact of listener traits, that is, age, age at onset of hearing loss, duration of CI use, and working memory capacity, were examined relative to listening effort.The participants completed a dual-task paradigm with a primary task identifying sentences in noise and a secondary task measuring reaction time on a Stroop test. Performance was assessed for all participant groups at different signal-to-noise ratios (SNRs), ranging in 2-dB steps from 0 to +10 dB relative to an individual’s SNR-50, at which the speech recognition performance is 50% correct. Participants completed three questions on listening effort, the Spatial Hearing Questionnaire, and a reading span test.All 46 participants were adults. The four participant groups included (1) 12 individuals with normal hearing, (2) 10 with unilateral CIs, (3) 12 with bilateral CIs, and (4) 12 with a hybrid short-electrode CI and bilateral residual hearing.Results from the dual-task experiment were compared using a mixed 4 (hearing group) by 6 (SNR condition) analysis of variance (ANOVA). Questionnaire results were compared using one-way ANOVAs, and correlations between listener traits and the objective and subjective measures were compared using Pearson correlation coefficients.Significant differences were found in speech perception among the normal-hearing and the unilateral and the bilateral CI groups. There was no difference in primary task performance among the hybrid CI and the normal-hearing groups. Across the six SNR conditions, listening effort improved to a greater degree for the normal-hearing group compared to the CI groups. However, there was no significant difference in listening effort between the CI groups. The subjective measures revealed significant differences between the normal-hearing and CI groups, but no difference among the three CI groups. Across all groups, age was significantly correlated with listening effort. We found no relationship between listening effort and the age at the onset of hearing loss, age at implantation, the duration of CI use, and working memory capacity for these participants.Listening effort was reduced to a greater degree for the normal-hearing group compared to the CI users. There was no significant difference in listening effort among the CI groups. For the CI users in this study, age was a significant factor with regard to listening effort, whereas other variables such as the duration of CI use and the age at the onset of hearing loss were not significantly related to listening effort.

Purpose The visual Text Reception Threshold (TRT) test (Zekveld et al., 2007) has been designed to assess modality-general factors relevant for speech perception in noise. In the last decade, the test has been adopted in audiology labs worldwide. The 1st aim of this study was to examine which factors best predict interindividual differences in the TRT. Second, we aimed to assess the relationships between the TRT and the speech reception thresholds (SRTs) estimated in various conditions. Method First, we reviewed studies reporting relationships between the TRT and the auditory and/or cognitive factors and formulated specific hypotheses regarding the TRT predictors. These hypotheses were tested using a prediction model applied to a rich data set of 180 hearing aid users. In separate association models, we tested the relationships between the TRT and the various SRTs and subjective hearing difficulties, while taking into account potential confounding variables. Results The results of the prediction model indicate that the TRT is predicted by the ability to fill in missing words in incomplete sentences, by lexical access speed, and by working memory capacity. Furthermore, in line with previous studies, a moderate association between higher age, poorer pure-tone hearing acuity, and poorer TRTs was observed. Better TRTs were associated with better SRTs for the correct perception of 50% of Hagerman matrix sentences in a 4-talker babble, as well as with better subjective ratings of speech perception. Age and pure-tone hearing thresholds significantly confounded these associations. The associations of the TRT with SRTs estimated in other conditions and with subjective qualities of hearing were not statistically significant when adjusting for age and pure-tone average. Conclusions We conclude that the abilities tapped into by the TRT test include processes relevant for speeded lexical decision making when completing partly masked sentences and that these processes require working memory capacity. Furthermore, the TRT is associated with the SRT of hearing aid users as estimated in a challenging condition that includes informational masking and with experienced difficulties with speech perception in daily-life conditions. The current results underline the value of using the TRT test in studies involving speech perception and aid in the interpretation of findings acquired using the test.

Significant Difference

Both verbal and visuospatial working memory adding to selective attention, have been examined in two groups (Mean age = 12.59 years old). One of the two groups displaying math learning disabilities (n=36), this group acts as an experimental group, and the other group without learning disabilities acts as a control group (n=36), the two groups were matched for age and IQ. The two groups presented with complex span tasks to assess working memory capacity (WMC), operation span task (OSPAN) used to assess verbal working memory capacity, symmetry span task used to assess visuospatial working memory capacity; the two previous tasks administrated automatically by using computers. Selective attention assessed in the two groups by using a colored square task (CST) that used for assessing visual selective attention and it administrated automatically. Results revealed that the performance of children with MLD was lower than the control group (typically achieving children) in both verbal and visuospatial working memory, moreover, the two groups differed in the number of correct responses (accuracy) in visual selective attention for typically achieved children, but there is no significant difference between them in response time (speed).

The Relationship

As listening conditions worsen (e.g., background noise increases), additional cognitive effort is required to process speech. The existing literature is mixed on whether and how cognitive traits like working memory capacity moderate the amount of effort that listeners must expend to successfully understand speech. Here, we validate a dual-task measure of listening effort (Experiment 1) and demonstrate that, for normal-hearing young adults, effort increases as listening conditions worsen, but working memory capacity is unrelated to the amount of effort expended (Experiment 2). We propose that previous research may have overestimated the relationship between listening effort and working memory capacity by measuring listening effort using recall-based tasks, but the relationship between the two disappears when using a measure of listening effort that does not require recall. These results suggest caution in making the general assumption that working memory capacity is related to the amount of effort expended during a listening task.

The present study explores the relative efficacy of recasts over metalinguistic feedback on the learning of the Englishthat-trace filter and how working memory capacity (WMC) is related to the extent to which learners can benefit from recasts and metalinguistic feedback. Fifty-four Korean English as a foreign language (EFL) learners from six intact classes at a university formed two experimental groups (recasts and metalinguistic feedback) and one control group and carried out two first language (L1) working memory (WM) span tasks (reading span and operation span tasks). The two experimental groups participated in two information gap activities over two treatment sessions, during which they were required to ask questions involving thethat-trace filter and received corrective feedback (either recasts or metalinguistic feedback) on their erroneous utterances. Two dependent variable measures (a written production test and a grammaticality judgment test) were administered in each test session (pretest and immediate posttest). Results showed that recasts were as effective as metalinguistic feedback in facilitating the acquisition of the target construction. This may, to some extent, be attributable to the blocking of modified output opportunities specifically designed in this study to prevent modified output from playing a potential role as a confound. Also, individual differences in WMC significantly predicted, and thus mediated the effects of, recasts but not metalinguistic feedback, on the acquisition of thethat-trace filter. This suggests that executive attention or attention control (considered as a critical component of WMC) is involved in the noticing of recasts, but not in the noticing of metalinguistic feedback.
