Background/Objectives: The ability of young adults to control their balance is generally effortless and can occur automatically with minimal cognitive involvement. However, this ability may be compromised when integration conflicts arise due to impairments in vestibular, visual, or somatosensory functions. Hence, psychomotor symptoms linked to emotional states can also influence postural control. The purpose of this study was to understand the effects of anxiety and depression on balance in young adults. Methods: Our study included 50 young adults (21.86 ± 2.63 years), consisting of 13 males and 37 females. Anxiety and depressive symptoms were evaluated using the Hospital Anxiety and Depression Scale (HADS), while balance was assessed through the Modified Clinical Test for the Sensory Interaction on Balance (mCTSIB). Data analysis was conducted using Pearson’s correlation coefficient test and the Kruskal–Wallis test. Results: Pearson’s correlation analysis indicated that young adults exhibited stable postural control. However, a positive correlation (0.259, p < 0.1) was observed between anxiety levels and the sway index. Additionally, positive correlations were found between anxiety and both somatosensory (0.281, p < 0.05) and visual (0.276, p < 0.1) ratios. Conclusions: The results suggest that higher anxiety levels are associated with reduced postural balance, with sensory inputs, particularly visual and somatosensory, playing a key role in this decreased stability.

To describe an application's development and validation process that aims to track hearing difficulties in adverse environments (a listening effort application). 71 subjects were evaluated, divided into two groups: 30 subjects aged between 18 and 30, and 41 subjects aged between 40 and 65. All subjects had European Portuguese as their native language; the Montreal Cognitive Assessment (MOCA) scored above 24, and all could read and write. All subjects performed the intelligibility test in noise and the test of listening effort. The two tests were randomly applied in the free field in the audiometric cabin and the application. There were no statistically significant differences between the results of the two methods (p>0.05). For the group aged between 40 and 65 years old, the ROC curve showed that intelligibility inferior to 68.5% and the number of correct answers lower than 1,5 in the listening effort test are the optimal cut-off for referral to further management. Both tests showed low sensitivity and specificity regarding individuals between 18 and 30 years old, indicating that the application is inappropriate for this age group. The application is valid and can contribute to the screening and self-awareness of listening difficulties in middle age, with a reduction in the prevalence of dementia soon.

Background and Objectives: Speech-in-noise testing is essential for evaluating functional hearing abilities in clinical practice. Although the Quick Speech-in-Noise test (QuickSIN) is widely used, no equivalent tool existed for European Portuguese. This study aimed to develop a Speech-in-Noise Test for European Portuguese (SiN-EP), linguistically adapted and calibrated for native speakers, to support clinical assessment of speech perception in realistic listening environments. Materials and Methods: The SiN-EP was developed through a multi-stage process. Sentences were drafted to reflect natural speech patterns and reviewed by native speakers for clarity and grammatical accuracy. Selected sentences were recorded by a female native speaker in a controlled acoustic environment and mixed with multi-talker babble at signal-to-noise ratios (SNR (dB)) from 25 to 0 SNR (dB). A pre-test in a free-field setting at 65 dB SPL was conducted with fifteen normal-hearing young adults. Participants repeated each sentence, and their responses were analyzed to refine list composition, adjust difficulty, and ensure phonetic balance. Results: Intelligibility decreased systematically as SNR (dB) worsened, with ceiling effects at 25 and 20 SNR (dB). At 5 SNR (dB), high variability was observed, with set 5 showing disproportionate difficulty and set 14 containing an incomplete sentence; both were removed. At 0 SNR (dB), all sets demonstrated expected low intelligibility. The final test comprises thirteen lists of six sentences, each maintaining stable intelligibility, phonetic representativeness, and consistent difficulty across SNRs (dB). Conclusions: The SiN-EP provides a linguistically appropriate, phonetically balanced, and SNR (dB) calibrated instrument for assessing speech-in-noise perception in European Portuguese. The refinement process improved reliability and list equivalence, supporting the test’s clinical and research applicability. The SiN-EP fills a critical gap in assessing speech-in-noise perception in European Portuguese speakers, providing a reliable tool for both clinical and research applications.

Background: Working memory (WM) is essential for reasoning, learning, and everyday cognitive tasks and can be influenced by stress. This study investigated the relationship between perceived stress and auditory working memory in 24 adults (16 women, 8 men; median age = 22). Methods: Participants completed the Perceived Stress Scale (PSS-10) and a pseudoword span task assessing auditory memory under phonologically demanding conditions. Results: Participants with higher stress levels exhibited greater variability and a decline in performance across pseudowords sets, particularly in the final set. Correlational analyses revealed that higher PSS-10 scores were significantly associated with lower accuracy on the most demanding memory set (r = −0.467, p = 0.021) and with younger age (r = −0.489, p = 0.015). These findings suggest that elevated stress may impair auditory working memory, with younger adults reporting higher perceived stress. Conclusions: This study highlights the importance of considering stress levels in cognitive assessments and supports the hypothesis that stress negatively affects working memory efficiency, particularly in tasks requiring phonological processing.

Background/Objectives: Shift work in healthcare professionals affects performance in high cognitive processing, especially in complex environments. However, the beneficial effects that working in complex environments may have on auditory–cognitive processing remain unknown. These professionals face increased challenges in decision-making due to factors such as noise exposure and sleep disturbances, which may lead to the development of enhanced auditory–cognitive resources. This study aims to investigate the associations between shift work and auditory–cognitive processing in middle-aged healthcare workers. Methods: Thirty middle-aged healthcare workers were equally allocated to a shift worker (SW) or a fixed-schedule worker (FSW) group. Performance on a cognitive test, and in pure-tone audiometry, speech in quiet and noise, and listening effort were used to explore whether correlations were specific to shift work. Results: Exploratory analyses indicated that shift workers tended to perform better in visuospatial/executive function, memory recall, memory index, orientation, and total MoCA score domains compared to fixed-schedule workers. In the SW group, hearing thresholds correlated with memory recall and memory index. In the FSW group, hearing thresholds correlated with orientation, memory index, and total MoCA score, while listening effort correlated with naming, and speech intelligibility in quiet correlated with total MoCA scores. Conclusions: These exploratory findings suggest that shift work may be linked to distinct auditory–cognitive patterns, with potential compensatory mechanisms in visuospatial/executive functions and memory among middle-aged healthcare workers. Larger, longitudinal studies are warranted to confirm whether these patterns reflect true adaptive mechanisms.

Background and Objectives: The Quick Speech-in-Noise test is a widely used clinical tool for assessing an individual’s ability to understand speech in the presence of background noise. Building on this framework, the present study aimed to develop a Speech-in-Noise Test for European Portuguese (SiN-EP), specifically adapted for native speakers of European Portuguese. The goal was to create a reliable and linguistically appropriate tool to evaluate speech perception under realistic listening conditions. Materials and Methods: The development of the SiN-EP involved several stages. Sentences were drafted to reflect natural speech patterns and reviewed by native speakers for clarity and grammatical correctness. Selected sentences were recorded by a female native speaker in a controlled environment. The recordings were then combined with multi-talker babble noise at varying levels to simulate different listening situations, ranging from easy to challenging. A pre-test was conducted in a free field setting at 65 dB SPL with fifteen young adults with normal hearing. Participants listened to and repeated each sentence, and their responses were used to refine the test materials. Results: Participants understood the sentences clearly and consistently across all listening conditions, showing that the SiN-EP effectively reflects speech perception in noise. The final version included thirteen lists of six sentences, carefully designed to maintain natural phonetic balance and realistic speech structure. Conclusion: The SiN-EP represents a significant advancement in evaluating speech understanding in noise for Portuguese-speaking populations. This standardized and linguistically adapted test provides valuable information about auditory performance and supports both clinical assessments and research on hearing and auditory processing challenges.
