- Tradução e adaptação de um software de treinamento da escuta no ruído para o português brasileiro(2018) CALARGA, Karenina Santos; ROCHA-MUNIZ, Caroline; JUTRAS, Benoît; SCHOCHAT, ElianeABSTRACT Purpose To translate and to adapt the software “LEB”, verify its effectiveness and playability in a group of students without hearing and / or learning complaints. Methods (I) Effectiveness was investigated by analyzing the performance of two paired groups before and after training in the compressed speech test. The trained group (TG), composed by 22 students aged 9 to 10 years old, received training with the software and the control group (CG), composed by 20 students of the same age, did not receive any type of stimulation; (II) after the training, the subjects of the TG responded to a qualitative evaluation about the software. Results The commands were understood and executed easily and effectively. The questionnaire revealed that LEB was well accepted and stimulating, providing new learning. The GT presented significant evolutions in comparison to the control group. Conclusions The success in the software’s translation, adaptation and gameplay process is evidenced by the observed changes in the auditory closure ability, suggesting its effectiveness for training speech perception in the noise.
- The influence of oral language environment on auditory development(2020) MONTEIRO, Thais Regina; ROCHA-MUNIZ, Caroline Nunes; FILIPPINI, Renata; MORAIS, Aline Albuquerque; SCHOCHAT, ElianeObjective: The purpose of this study was to compare the auditory processing of hearing children who were immersed in an oral language environment during early childhood with that of children who were poorly exposed to oral language during the same period. Methods: Sixty children aged between 5 and 10 years participated in this study. They were divided in two groups. Group 1 comprised of 30 children who had deaf signer parents, and Group 2 comprised of 30 children who had hearing parents. These children underwent the following auditory processing tests: Pediatric Speech Intelligibility, Dichotic Digits, Pitch Pattern Sequence, Gaps-in-Noise, and Memory Tests for Instrumental and Verbal sounds. Results: Group 1 had significantly poorer performance than that of Group 2 in all tests. In addition, an analysis by age range revealed that the differences between groups were more pronounced in younger children (5-6 years). Conclusion: The results indicate that the development of auditory skills is strongly influenced by access to oral linguistic sounds. Thus, a child's exposure to an oral language environment from birth is important to the adequate development of the auditory system functions.
- Medial olivocochlear function in children with poor speech-in-noise performance and language disorder(2017) ROCHA-MUNIZ, Caroline Nunes; CARVALLO, Renata Mota Mamede; SCHOCHAT, ElianeObjectives: Contralateral masking of transient-evoked otoacoustic emissions is a phenomenon that suggests an inhibitory effect of the olivocochlear efferent auditory pathway. Many studies have been inconclusive in demonstrating a clear connection between this system and a behavioral speech-in-noise listening skill. The purpose of this study was to investigate the activation of a medial olivocochlear (MOC) efferent in children with poor speech-in-noise (PSIN) performance and children with language impairment and PSIN (SLI + PSIN). Methods: Transient evoked otoacoustic emissions (TEOAEs) with and without contralateral white noise were tested in 52 children (between 6 and 12 years). These children were arranged in three groups: typical development (TD) (n = 25), PSIN (n = 14) and SLI + PSI (n = 13). Results: PSIN and SLI + PSI groups presented reduced otoacoustic emission suppression in comparison with the TD group. Conclusion: Our finding suggests differences in MOC function among children with typical development and children with poor SIN and language problems.
- Investigation of auditory processing disorder and language impairment using the speech-evoked auditory brainstem response(2012) ROCHA-MUNIZ, Caroline N.; BEFI-LOPES, Debora M.; SCHOCHAT, ElianeThis study investigated whether there are differences in the Speech-Evoked Auditory Brainstem Response among children with Typical Development (TD), (Central) Auditory Processing Disorder (C) APD, and Language Impairment (LI). The speech-evoked Auditory Brainstem Response was tested in 57 children (ages 6-12). The children were placed into three groups: TD (n = 18), (C)APD (n = 18) and LI (n = 21). Speech-evoked ABR were elicited using the five-formant syllable/da/. Three dimensions were defined for analysis, including timing, harmonics, and pitch. A comparative analysis of the responses between the typical development children and children with (C)APD and LI revealed abnormal encoding of the speech acoustic features that are characteristics of speech perception in children with (C)APD and LI, although the two groups differed in their abnormalities. While the children with (C)APD might had a greater difficulty distinguishing stimuli based on timing cues, the children with LI had the additional difficulty of distinguishing speech harmonics, which are important to the identification of speech sounds. These data suggested that an inefficient representation of crucial components of speech sounds may contribute to the difficulties with language processing found in children with LI. Furthermore, these findings may indicate that the neural processes mediated by the auditory brainstem differ among children with auditory processing and speech-language disorders.
- Stroke in children and adolescents: Analysis of electrophysiological and behavioral assessment findings of auditory processing(2023) STADULNI, Andreia Rodrigues Parnoff; SLEIFER, Pricila; BERTICELLI, Amanda Zanatta; RIESGO, Rudimar; ROCHA-MUNIZ, Carolina Nunes; SCHOCHAT, ElianePurpose: This study aimed to analyze the auditory processing behavior of children and adolescents diagnosed with stroke and compare it with that of typically developing individuals.Methods: This was an analytical cross-sectional study involving 48 participants aged between 7 and 17 years with adequate schooling for age and grade, allocated equally to two groups: Stroke (SG) and Control Groups (CG). For the SG, cases identified between 2003 and 2018 were considered. In the CG, school-aged participants with typical development were randomized. After screening for differential audiological assessment and confirmation of auditory pathway integrity at the brainstem level, binaural analyses of the auditory processing behavior were conducted using the Dichotic Digit Test (DDT), Frequency Pattern Test (FPT), and electrophysiological assessment (P300). The Shapiro-Wilk test for normality was conducted, followed by the T and Mann-Whitney tests, with a 95 % confidence level and significance offset at p < 0.05, using the SPSS software (IBM (R), v. 22.)Results: The CG performed better in terms of auditory processing. These differences were significant (p < 0.0001) for the binaural integration of DDT, FPT humming and Labeling, and P300 latency. The P300 results were similar; however, with a greater amplitude in the SG. Conclusion: This study showed that children and adolescents with stroke performed worse in electrophysiological and behavioral tests of auditory processing assessed using the auditory evoked potentials. These data reinforce the hypothesis that stroke-related lesions compromise the neural mechanisms underlying auditory processing.
- Auditory temporal resolution and backward masking in musicians with absolute pitch(2023) LEITE FILHO, Carlos Alberto; ROCHA-MUNIZ, Caroline Nunes; PEREIRA, Liliane Desgualdo; SCHOCHAT, ElianeAmong the many questions regarding the ability to effortlessly name musical notes without a reference, also known as absolute pitch, the neural processes by which this phenomenon operates are still a matter of debate. Although a perceptual subprocess is currently accepted by the literature, the participation of some aspects of auditory processing still needs to be determined. We conducted two experiments to investigate the relationship between absolute pitch and two aspects of auditory temporal processing, namely temporal resolution and backward masking. In the first experiment, musicians were organized into two groups according to the presence of absolute pitch, as determined by a pitch identification test, and compared regarding their performance in the Gaps-in-Noise test, a gap detection task for assessing temporal resolution. Despite the lack of statistically significant difference between the groups, the Gaps-in-Noise test measures were significant predictors of the measures for pitch naming precision, even after controlling for possible confounding variables. In the second experiment, another two groups of musicians with and without absolute pitch were submitted to the backward masking test, with no difference between the groups and no correlation between backward masking and absolute pitch measures. The results from both experiments suggest that only part of temporal processing is involved in absolute pitch, indicating that not all aspects of auditory perception are related to the perceptual subprocess. Possible explanations for these findings include the notable overlap of brain areas involved in both temporal resolution and absolute pitch, which is not present in the case of backward masking, and the relevance of temporal resolution to analyze the temporal fine structure of sound in pitch perception.
- Investigation of the neural discrimination of acoustic characteristics of speech sounds in normal-hearing individuals through Frequency-following Response (FFR)(2021) ROCHA-MUNIZ, Caroline Nunes; SCHOCHAT, ElianePurpose: To evaluate how the auditory pathways encode and discriminate the plosive syllables [ga], [da] and [ba] using the auditory evoked Frequency-following Response (FFR) in children with typical development. Methods: Twenty children aged 6-12 years were evaluated using the FFR for the [ga], [da] and [ba] stimuli. The stimuli were composed of six formants and were differentiated in the F2 to F3 transition (transient portion). The other formants were identical in the three syllables (sustained portion). The latencies of the 16 waves of the transient portion (<70ms) and of the 21 waves of the sustained portion (90-160ms) of the stimuli were analyzed in the neural responses obtained for each of the syllables. Results: The transient portion latencies were different in the three syllables, indicating a distinction in the acoustic characteristics of these syllables through their neural representations. In addition, the transient portion latencies progressively increased in the following order: [ga] <[da] <[ba], whereas no significant differences were observed in the sustained portion. Conclusion: The FFR proved to be an efficient tool to investigate the subcortical acoustic differences in speech sounds, since it demonstrated different electrophysiological responses for the three evoked syllables. Changes in latency were observed in the transient portion (consonants) but not in the sustained portion (vowels) for the three stimuli. These results indicate the neural ability to distinguish between acoustic characteristics of the [ga], [da] and [ba] stimuli.
- Efficacy of auditory training in elderly subjects(2015) MORAIS, Aline Albuquerque; ROCHA-MUNIZ, Caroline Nunes; SCHOCHAT, ElianeAuditory training (AT) has been used for auditory rehabilitation in elderly individuals and is an effective tool for optimizing speech processing in this population. However, it is necessary to distinguish training-related improvements from placebo and test-retest effects. Thus, we investigated the efficacy of short-term AT [acoustically controlled auditory training (ACAT)] in elderly subjects through behavioral measures and P300. Sixteen elderly individuals with auditory processing disorder (APD) received an initial evaluation (evaluation 1 E1) consisting of behavioral and electrophysiological tests (P300 evoked by tone burst and speech sounds) to evaluate their auditory processing. The individuals were divided into two groups. The Active Control Group (n = 8) underwent placebo training. The Passive Control Group (n = 8) did not receive any intervention. After 12 weeks, the subjects were revaluated (evaluation 2 - E2). Then, all of the subjects underwent ACAT. Following another 12 weeks (eight training sessions), they underwent the final evaluation (evaluation 3 - E3). There was no significant difference between E1 and E2 in the behavioral test [F(9.6) = 0.06, p = 0.92, lambda de Wilks = 0.65)] or P300 [F(8.7) = 2.11, p = 0.17, lambda de Wilks = 0.29] (discarding the presence of placebo effects and test-retest). A significant improvement was observed between the pre- and post-ACAT conditions (E2 and E3) for all auditory skills according to the behavioral methods [F(4.27) = 0.18, p = 0.94, lambda de Wilks = 0.97]. However, the same result was not observed for P300 in any condition. There was no significant difference between P300 stimuli. The ACAT improved the behavioral performance of the elderly for all auditory skills and was an effective method for hearing rehabilitation.
- Ongoing maturation in the time-compressed speech test(2018) RABELO, Camila Maia; ROCHA-MUNIZ, Caroline Nunes; SCHOCHAT, ElianeOBJECTIVES: To verify the neuromaturational influence in the ability of auditory closure, that is, to verify the performance of children and young adults in the ability of auditory closure, through the time compressed speech test (TCS). METHODS: Thirty children (8 to 10 years old) and 30 young adults (16 to 24 years old) with normal hearing without complaints (neurological, cognitive, auditory processing) who performed TFC (monosyllables and disyllables) with a compression ratio of 60% in both ears. Statistical analysis was performed using analysis of variance (ANOVA) and ANOVA with repeated measures with a significance level of 0.05. The minimum statistical power was 80%. RESULTS: In the comparison between ears, there was no significant difference between groups for the monosyllables. For disyllables, the second ear tested was better in children, and the right ear was better than the left ear for young adults. In the comparison between modalities (monosyllables and disyllables), children did not show significant differences. The performance of the young adults was better in the disyllables in both ears. Comparing the age groups, the young adults were better than the children for both modalities and ears. CONCLUSION: The study has demonstrated the influence and impact of age (maturational factor) on TCS test performance, showing the importance of establishing normality patterns for various age groups to provide a standardized tool for evaluation of auditory closure ability.
- Association between language development and auditory processing disorders(2014) ROCHA-MUNIZ, Caroline Nunes; ZACHI, Elaine Cristina; TEIXEIRA, Rosani Aparecida Antunes; VENTURA, Dora Fix; BEFI-LOPES, Debora Maria; SCHOCHAT, ElianeIntroduction: It is crucial to understand the complex processing of acoustic stimuli along the auditory pathway;comprehension of this complex processing can facilitate our understanding of the processes that underlie normal and altered human communication. Aim: To investigate the performance and lateralization effects on auditory processing assessment in children with specific language impairment (SLI), relating these findings to those obtained in children with auditory processing disorder (APD) and typical development (TD). Material and methods: Prospective study. Seventy-five children, aged 6-12 years, were separated in three groups: 25 children with SLI, 25 children with APD, and 25 children with TD. All went through the following tests: speech-in-noise test, Dichotic Digit test and Pitch Pattern Sequencing test. Results: The effects of lateralization were observed only in the SLI group, with the left ear presenting much lower scores than those presented to the right ear. The inter-group analysis has shown that in all tests children from APD and SLI groups had significantly poorer performance compared to TD group. Moreover, SLI group presented worse results than APD group. Conclusion: This study has shown, in children with SLI, an inefficient processing of essential sound components and an effect of lateralization. These findings may indicate that neural processes (required for auditory processing) are different between auditory processing and speech disorders.
