bookPart Avaliação neurolinguística do idoso(2014) MANSUR, Leticia Lessa; SCHOCHAT, Eliane; SILAGI, Marcela Lima; RABELO, Camila Maia- Healthy Aging and Compensation of Sentence Comprehension Auditory Deficits(2015) SILAGI, Marcela Lima; RABELO, Camila Maia; SCHOCHAT, Eliane; MANSUR, Leticia LessaObjectives. To analyze the effect of aging on sentence auditory comprehension and to study the relationship between this language skill and cognitive functions (attention, working memory, and executive functions). Methods. A total of 90 healthy subjects were divided into three groups: adults (50-59 years), young-old (60-69 years), and old-old (70-80 years). Subjects were assessed using the Revised Token Test. The measures used for performance analysis were number of correct answers (accuracy) and execution time of commands on the different subtests. Results. Regarding accuracy, groups showed similar performance on the first blocks, but the young-old and old-old performed worse than adults on blocks 9 and 10. With respect to execution time, groups differed from block 2 (i.e., the groups differed for all blocks, except for block 1), with the worst performance observed in the old-old group, followed by that of the young-old group. Therefore, the elderly required more time to attain performance similar to that of adults, showing that time measurements are more sensitive for detecting the effects of age. Sentence comprehension ability is correlated with cognitive test performance, especially for global cognition and working memory tests. Conclusions. Healthy aging is characterized by the ability to compensate for difficulties in linguistic processing, which allows the elderly to maintain functional communication.
- Impact of Educational Level on Performance on Auditory Processing Tests(2016) MURPHY, Cristina F. B.; RABELO, CamilaM.; SILAGI, MarcelaL.; MANSURAND, Leticia L.; SCHOCHAT, ElianeResearch has demonstrated that a higher level of education is associated with better performance on cognitive tests among middle-aged and elderly people. However, the effects of education on auditory processing skills have not yet been evaluated. Previous demonstrations of sensory-cognitive interactions in the aging process indicate the potential importance of this topic. Therefore, the primary purpose of this study was to investigate the performance of middle-aged and elderly people with different levels of formal education on auditory processing tests. A total of 177 adults with no evidence of cognitive, psychological or neurological conditions took part in the research. The participants completed a series of auditory assessments, including dichotic digit, frequency pattern and speech-in-noise tests. A working memory test was also performed to investigate the extent to which auditory processing and cognitive performance were associated. The results demonstrated positive but weak correlations between years of schooling and performance on all of the tests applied. The factor ""years of schooling"" was also one of the best predictors of frequency pattern and speech-in-noise test performance. Additionally, performance on the working memory, frequency pattern and dichotic digit tests was also correlated, suggesting that the influence of educational level on auditory processing performance might be associated with the cognitive demand of the auditory processing tests rather than auditory sensory aspects itself. Longitudinal research is required to investigate the causal relationship between educational level and auditory processing skills.
- Auditory Processing Performance of the Middle-Aged and Elderly: Auditory or Cognitive Decline?(2018) MURPHY, Cristina F. B.; RABELO, Camila M.; SILAGI, Marcela L.; MANSUR, Leticia L.; BAMIOU, Doris E.; SCHOCHAT, ElianeBackground: Despite the well-established relationship between aging and auditory processing decline, identifying the extent to which age effect is the main factor on auditory processing performance remains a great challenge due to the co-occurrence of age-related hearing loss and age-related cognitive decline as potential confounding factors. Purpose: To investigate the effects of age-related hearing loss and working memory on the clinical evaluation of auditory processing of middle-aged and elderly. Research Design: Cross-sectional study. Study Sample: A total of 77 adults between 50 and 70 yr of age were invited to participate in the study. Data Collection and Analysis: The participants were recruited from a larger study that focused on the assessment and management of sensory and cognitive skills in elderly participants. Only participants with normal hearing or mild-to-moderate age-related hearing loss, with no evidence of cognitive, psychological, or neurological conditions were included. Speech-in-noise, dichotic digit, and frequency pattern tests were conducted as well as a working memory test. The hearing loss effect was investigated using an audibility index, calculated from the audiometric threshold. The performance on the digit span test was used to investigate working memory effects. Both hearing loss and working memory effects were investigated via correlation and regression analyses, partialling out age effects. The significance level was set at p < 0.05. Results: The results demonstrated that, while hearing loss was associated to the speech-in-noise performance, working memory was associated to the frequency pattern and dichotic digit performances. Regression analyses confirmed the relative contribution of hearing loss to the variance in speech-in-noise and working memory test to the variance in frequency pattern and dichotic digit test performance. Conclusions: The performance decline of the elderly in auditory processing tests may be partially attributable to the working memory performance and, consequently, to the cognitive decline exhibited by this population. Mild-to-moderate hearing loss seems to affect performance on specific auditory processing tasks, such as speech in noise, reinforcing the idea that auditory processing disorder in the elderly might also be associated to auditory peripheral deficits.
- Communication map of elderly people: Sociodemographic and cognitive-linguistic aspects(2013) SILAGI, Marcela Lima; PERES, Aline Rufo; SCHOCHAT, Eliane; MANSUR, Leticia LessaABSTRACT Language and communication difficulties may occur in the elderly population. This is the case of the tip-of-the-tongue phenomenon and receptive and auditory comprehension difficulties. Few studies have focused on examining the effects of social exposure on maintaining communication in the aging process. Objectives: [1] To describe the communication map of healthy elderly subjects; [2] To search for associations between frequency and time dedicated to communication and cognitive and sociodemographic factors. Methods: Healthy elderly subjects were submitted to cognitive screening, the Token Test - Revised, and the Verbal Fluency test, and answered the ASHA-FACS and the Circles of Communication Partners questionnaires. Results: 55 subjects, 67% female, with ages over 60 years and varied schooling were included in the sample. Interlocutors in the circle of close friends and acquaintances predominated in the communication map, although the time devoted to communication with these partners was lower than in other circles. Overall, the elderly reported no deficits in language comprehension, with some reports of the tip-of-the-tongue phenomenon. Poor performances on the Token Test - Revised and in phonemic verbal fluency along with reports of communication functionality indicated that these subjects compensate for their problems. Conclusion: Older subjects with lower schooling tended to predominantly communicate within the family circle. Within other circles, the number of hours devoted to communication and dialogue partners was not associated with age or schooling. The time devoted to the circle of communication with friends may indicate cognitive difficulties.
- Effect of education on listening comprehension of sentences on healthy elderly: analysis of number of correct responses and task execution time(2017) SILAGI, Marcela Lima; RABELO, Camila Maia; SCHOCHAT, Eliane; MANSUR, Letícia LessaABSTRACT Purpose To analyze the effect of education on sentence listening comprehension on cognitively healthy elderly. Methods A total of 111 healthy elderly, aged 60-80 years of both genders were divided into two groups according to educational level: low education (0-8 years of formal education) and high education (≥9 years of formal education). The participants were assessed using the Revised Token Test, an instrument that supports the evaluation of auditory comprehension of orders with different working memory and syntactic complexity demands. The indicators used for performance analysis were the number of correct responses (accuracy analysis) and task execution time (temporal analysis) in the different blocks. Results The low educated group had a lower number of correct responses than the high educated group on all blocks of the test. In the temporal analysis, participants with low education had longer execution time for commands on the first four blocks related to working memory. However, the two groups had similar execution time for blocks more related to syntactic comprehension. Conclusion Education influenced sentence listening comprehension on elderly. Temporal analysis allowed to infer over the relationship between comprehension and other cognitive abilities, and to observe that the low educated elderly did not use effective compensation strategies to improve their performances on the task. Therefore, low educational level, associated with aging, may potentialize the risks for language decline.
