The results were analyzed using the paired t-test and ANOVA for repeated measures, applied by the Bonferroni post-hoc test (p-value <0.05).Results: Less interference from modulated noise was identified in the latency and amplitude measurements of cortical components, generating a significant reduction in P1 latency and an increase in P2 amplitude in both groups of participants. Stable noise generated higher electrophysiological and behavioral thresholds compared to modulated noise. A greater magnitude of BMM was observed in the young-adult group.Conclusion: In both groups of participants, less interference from modulated noise was identified in the encoding time of the neural auditory response and in the process of neural discrimination of speech. Furthermore, behavioral and electrophysiological thresholds were typically higher in stable noise when compared to modulated noise, pointing to a correspondence between BMM measurements between hearing domains. The magnitude of the higher BMM in the young-adult group, especially in the electrophysiological domain, suggests a greater temporal resolution ability in younger individuals.","PeriodicalId":46547,"journal":{"name":"CoDAS","volume":"37 1","pages":"e20230339"},"PeriodicalIF":0.9,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11801197/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143190642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Orofacial Myofunctional Evaluation with Scores (OMES) form was used to evaluate the clinical aspects of mastication.

Additionally, the activation index and muscle symmetry were measured.Results: a preferentially unilateral chewing pattern was observed in 12 (54.5%) participants. Masticatory patterns did not influence electrical activation during any of the tasks, nor did occlusal guidance during maximum intercuspation or mastication. The percentage of muscle activation during maximal intercuspation approached half of the total activation during spontaneous chewing.

The classifications were made remotely and documented on a form.Results: The average percentage of correct responses by the students, in relation to the gold standard, was significantly higher for the 3-point scale. There was no significant interaction between the order of presentation and the scale for the percentage of correct classifications.

The argument remains whether the stuttering dysfluencies have a motor or a linguistic foundation. Though stuttering is considered a speech-motor disorder, linguistic factors are increasingly reported to play a role in stuttering. Current literature points towards deficits in speech-related motor areas of the brain to abnormalities in linguistic planning and phonological memory playing a role in stuttering. Examining cross-linguistic generalization of treatment gains from treated to untreated language in bilinguals who stutter may provide a unique opportunity to explore the motor and linguistic factors in stuttering.Methods: In the current study, we explored this potential by experimentally controlling the language of treatment in bilinguals with stuttering (BWS). We hypothesized that if the dysfluencies in stuttering arise from the underlying motor deficits, then the language of treatment would not play a significant role in cross-linguistic generalization. Sixteen BWS were given transcranial direct current stimulation (tDCS) along with behavioral intervention for three weeks. The language of treatment was randomized, wherein participants in one group received behavioral intervention in their dominant language and the other in their non-dominant language.Results: Results showed that participants in both groups showed a reduction in their stuttering dysfluencies (% stuttered syllables) regardless of the language of treatment, and the treatment gains were generalized to the non-treated language.Conclusion: Linguistic factors such as language dominance and structure of languages did not surface to play a role in the generalization, signaling the motoric nature of dysfluencies in stuttering.","PeriodicalId":46547,"journal":{"name":"CoDAS","volume":"37 1","pages":"e20240186"},"PeriodicalIF":0.9,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11781365/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143068737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
