In the brief communication, we compared various national reports from other countries to see whether current care service for the dementia had integrative approach for the patients with hearing loss in Korea. We also discussed a need of systematic hearing care for the elderly with dementia who was also a suspected case of aged-related hearing loss because many studies had confirmed that untreated hearing loss has a negative effect on dementia and vice versa. After analyzing the national policy from several countries, we found that the systems had been well established to screen dementia patients by using various clinical tests in UK, Canada, and Japan who provided appropriate services by classifying types of the dementia. Remarkably, the hearing test was included as the testing protocol for the dementia in Canada and the experts such as speech pathologists and music therapists had worked in a non-pharmacotherapy program for the elderly with dementia in France. Unfortunately, the dementia policy of Korea needs to be refined when considering the hearing care/management in that the integrated management of hearing and dementia are important. In addition, the clinicians who work for the dementia care home need to know audiological knowledge. Since the auditory training and rehabilitation for the elderly can reduce increased rate of cognitive decline, we strongly recommend that auditory training should be a part of the cognitive rehabilitation programs in the dementia care home.","PeriodicalId":36841,"journal":{"name":"Audiology and Speech Research","volume":"75 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90269740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: A total of 23 students, consisting of 10 LLD students and 13 typically developing (TD) students, were recruited for this study. All students were tested to check their ability to define and understand homonyms. Results: Comparing the two groups, the overall definition accuracy and comprehension ability of homonyms were significantly lower in the LLD group than the TD group. In addition, when comparing the accuracy of individual definitions and ability to comprehend homophones according to the conditions (dominant/subordinate meaning) between the two groups, the LLD group showed lower performance than the TD group in both abilities. Both groups were found to have more difficulty with the subordinate meaning than with the dominant meaning. LLD group has difficulties at defining homonym than TD group in both meanings. On the other hand, the LLD group showed lower performance than the TD group in their ability to comprehend the subordinate meaning. There was no difference between the two groups in the ability to understand the dominant meaning. Conclusion: Therefore, when determining interventions for grade 1 to 3 students having learning disabilities, proper contextual clues should be used to improve their homonym comprehension.","PeriodicalId":36841,"journal":{"name":"Audiology and Speech Research","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89841101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: The test list consisted of 127 initial and 94 final consonant test items with meaningful one-syllable words and was developed in two types for each difficulty level. To verify the validity of the developed phoneme perception test tool, twenty children with normal hearing were tested for the validity of the results, and the contents were verified by experts in various fields. Results: As a result of comparing the rate of correct response according to the type of test item (initial vs. final consonant) and difficulty (easy vs. difficult item), the initial and easy responses were higher than the final and hard item, respectively, so the difficulty level of the test list was appropriate. In addition, there was no statistical difference in the rate of correct answers according to the test speakers, and the content validity analysis for experts verified that the developed test list was appropriate as a phoneme perception test tool for school-age children. Conclusion: The initial and final consonant test items developed through this study consisted of one target word and three examples which are a pair of minimum confrontations with the target word and are heteromorphic test lists consisting of easy and hard types according to the difficulty of the example. It could also be useful for not only the evaluation of the consonant perception ability but also rehabilitation.","PeriodicalId":36841,"journal":{"name":"Audiology and Speech Research","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81915289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their pure-tone average was 46.0 dB HL and the word recognition score was 72.1%. The CTs of low/high frequency bands were adjusted to 50/50 dB SPL, 50/65 dB SPL, 65/50 dB SPL and 60/65 dB SPL in multi-channel hearing aids.

Second, in the noise environment, the clarity of conversational speech, and loudness of the noise did not have any difference regardless of levels of CT.Conclusion: Based on current findings, the frequency bands setting of CT in the multi-channel hearing aids might provide changes to recognize Korean speech sounds, which may affect the adjustment of frequency band CT from multichannel hearing aids in the future.","PeriodicalId":36841,"journal":{"name":"Audiology and Speech Research","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78781360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first N100 component has been conceptualized as a pre-attentive response related to perception. The N100 response was modulated by the physical characteristics of stimuli such as type, intensity, and duration, and also depended on subject factors such as the internal state, neural activity, and cognition. As it was the first stimulus in a series, the N100 amplitude was relatively high but lowered for subsequent repetitions of stimuli (Brown et al., 2002; Clearwater et al., 2008). N200 has been known to be a comprehensive response of cortical, thalamic, and brainstem regions, although the source of N200 activation relied on some extent to the limbic and complex generating system in the region of the thalamus (Ponton et al., 2002). N200 was also thought to be sensitive to cognitive aspects such as task demands and attention (Näätänen & Picton, 1986). However, the latency of N200 exhibited conflicting findings depending on the age of participants (Amenedo & Díaz, 1998). As observed only during conscious stimulus attention, P300 was often found as a part of complex components of N200, which were categorized as endogenous potentials because even mere mental counting tasks for target stimuli could elicit them well (Kaga et al., 2014). P300 reflected the brain activity required to update working memory when changes occurred in the stimulus and variation of the amplitude indicated the degree of inclusion of the central nervous system activity involved in processing information (Verleger et al., 2014).
