Efferent inhibitory effect observed in otoacoustic emissions and auditory brainstem response in the neonatal population.

OBJECTIVE: To characterize the inhibitory effect (IE) in the otoacoustic emission (OAE) and auditory brainstem response (ABR) in newborns at high and low risk for hearing loss. DESIGN: Cross-sectional study. PATIENTS AND METHODS: Seventy-nine newborns at low risk for hearing loss and 46 at high risk underwent transient evoked OAE (TEOAE), distortion product OAE (DPOAE) and ABR testing with or without the presence of contralateral white noise presented at a level of 60 dB SPL. RESULTS: For both low- and high-risk newborns, there were no significant differences in IE between the left and right ears. There was a statistically significant difference in the right-ear IE between the low- and high-risk group for DPOAE and ABR testing. There was also greater agreement of the efferent system evaluation outcomes between TEOAE and ABR. CONCLUSIONS: ABR testing detected IE in a greater number of newborns in the low-risk, as compared to the high-risk group.

Dichotic Sentences Test Performance of Adults with communication complaints. / Desempenho no Teste Dicótico de Sentenças em Adultos com queixa comunicativa.

PURPOSE: To analyze the performance of normal-hearing adults with communication complaints in the Dichotic Sentences Test. METHODS: We selected from the database 15 normal-hearing participants with normal results in the Digits Dichotic Test, aged between 19 and 44 years, right-handed, who reported communicative complaints. The Dichotic Sentences Test was applied using two protocols consisting of four different combinations of lists called sequences 1 and 2, in the following order: training, divided attention step, right and left directed attention steps. RESULTS: In the first application sequence, the average performance in the divided attention step was 84.7% for the right ear and 60.67% for the left, with statistical difference between ears. The asymmetry between ears varied from -50% to 60%. In the directed attention step, the average performance was 99.33% for the right ear and 98% for the left, with no statistical difference. In the second application sequence, there was a tendency for better results, more pronounced for the left ear, with no statistical significance, with the performance variation and asymmetry between ears remaining high. In the comparison between the sequences, in the divided attention step, it was found that, for the right ear, 40% of the individuals did not vary, 33% performed worse, and 26.7% performed better; for the left ear, 6.6% did not vary, 20% performed worse, and 73.33% performed better. There was result stability in the directed attention step. CONCLUSION: The normal-hearing adults with communication complaints presented a heterogeneous profile, especially in the divided attention step, with a marked difference between ears and response variability.

OBJETIVO: Analisar o desempenho de adultos normo-ouvintes com queixa comunicativa no Teste Dicótico de Sentenças. MÉTODO: Selecionou-se em banco de dados, 15 participantes normo-ouvintes com resultados normais no Teste Dicótico de Dígitos, idades entre 19 a 44 anos, destros, que referiram queixa comunicativa. O Teste de Dicótico de Sentenças foi aplicado por meio de dois protocolos compostos por quatro diferentes combinações de listas denominados de sequências 1 e 2, de acordo com a seguinte ordem: treino, etapa de atenção dividida, etapas de atenção direcionada à direita e à esquerda. RESULTADOS: Na sequência de aplicação 1, a média de desempenho na etapa de atenção dividida foi 84,67% na orelha direita e 60,67% na esquerda, com diferença estatística entre orelhas, com assimetria entre orelhas variando de -50% a 60%. Na etapa de atenção direcionada, a média de desempenho foi 99,33% na orelha direita e 98% na esquerda, sem diferença estatística. Na sequência de aplicação 2, houve tendência de melhores resultados, mais acentuada na orelha esquerda, sem significância estatística, mantendo elevadas a variação de desempenho e a assimetria entre orelhas. Verificou-se na comparação entre as sequências, na etapa de atenção dividida, que na orelha direita 40% dos indivíduos não variaram, 33% pioraram, 26,7% melhoraram; na orelha esquerda, 6,6% não variaram, 20% pioraram e 73,33% melhoraram. Na etapa de atenção direcionada houve estabilidade nos resultados. CONCLUSÃO: Os adultos normo-ouvintes, com queixas comunicativas, apresentaram um perfil heterogêneo, especialmente na etapa de atenção dividida, com acentuada diferença entre as orelhas e variabilidade de respostas.

Auditory temporal resolution and backward masking in musicians with absolute pitch.

Among 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.

Stroke in children and adolescents: Analysis of electrophysiological and behavioral assessment findings of auditory processing.

PURPOSE: 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®, 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.

Evaluation of cognitive functions in the elderly with and without central auditory processing disorder. / Avaliação das funções cognitivas em idosos com e sem alterações no processamento auditivo central.

PURPOSE: Evaluate and compare the performance of cognitive functions between elderly with and without auditory processing disorders. METHODS: Twenty-eight healthy elderly (14 Control group and 14 Auditory Processing Disorder group - APD group) participated in the study. All elderly were submitted to (central) auditory processing evaluation, P300 event-related potential and brief cognitive battery (BCB). In the comparison between subjects, the Mann-Whitney test was applied and in the intra-subjects comparison, the Wilcoxon signed rank test was used. To verify if there was an association between the performance of the PAC and the cognitive variables, Spearman's correlation was used. RESULTS: There were no statistically significant differences between the Control and APD groups for the cognitive abilities assessed by BCB, as well as for the P300 cognitive potential variables. CONCLUSION: Elderly with auditory processing disorders do not seem to show greater cognitive difficulties compared to elderly of the same age group without auditory processing disorders, exception of the clock drawing test, whose task involves multiple cognitive functions, including visuospatial processing, executive function, semantic memory, and planning.

OBJETIVO: Avaliar e comparar as funções cognitivas entre idosos com e sem alteração do processamento auditivo central. MÉTODO: Vinte e oito idosos saudáveis (14 do grupo controle e 14 do grupo Transtorno do Processamento Auditivo Central - TPAC) participaram do estudo. Todos os idosos foram submetidos à bateria mínima de avaliação do processamento auditivo central (PAC), ao potencial auditivo cognitivo P300 e a bateria cognitiva breve (BCB). Na comparação entre sujeitos, foi aplicado o teste de Mann-Whitney e na comparação intra-sujeitos, utilizamos o teste de postos sinalizados de Wilcoxon. Para verificar se houve associação entre o desempenho do PAC e das variáveis cognitivas, foi utilizada a correlação de Spearman. RESULTADOS: Não houve diferenças estatisticamente significantes entre os grupos 'Controle' e TPAC para a maioria das habilidades cognitivas avaliadas por meio da BCB, bem como para as variáveis do potencial cognitivo P300. Contudo, houve diferença estatisticamente significante entre o desempenho do grupo 'Controle' e TPAC para a prova do desenho do relógio. Além disso, foi possível observar correlação entre o desempenho do teste do relógio e no TPF. CONCLUSÃO: Idosos com TPAC não apresentaram alteração na maior parte dos testes cognitivos, com exceção da prova do desenho do relógio, cuja tarefa envolve múltiplas funções cognitivas, incluindo processamento visuoespacial, função executiva, memória semântica e planejamento.

Ear and electrode effects reduce within-group variability in middle latency response amplitude measures.

OBJECTIVES: To establish normative amplitude values for relative difference measurements of the middle latency response (MLR) in normal-hearing pediatrics and to determine if these measurements provided a significant reduction of within-group variability when compared to raw, absolute amplitude measures. A relative amplitude difference is defined in the present paper as the difference in Na-Pa amplitude between two electrodes (e.g. |Na-Pa at C3 minus Na-Pa at C4|, or electrode effects) or between two ears (e.g. |Na-Pa on left ear stimulation minus Na-Pa on right ear stimulation|, or ear effects). In contrast, an absolute amplitude is defined as a single Na-Pa measurement made at one electrode for stimulation of one ear (e.g. Na-Pa measured at C3 on left ear stimulation). DESIGN: Cross-sectional study. STUDY SAMPLE: 155 pediatrics with normal peripheral and central hearing, and no history of psychological, neurological, or learning disability issues. RESULTS: Within-group variability was significantly smaller for relative differences when compared to absolute amplitude measures. Electrode effects showed significantly less variability than ear effects. Normative values for ear and electrode effects were reported. CONCLUSIONS: Relative differences may provide better utility in the clinical diagnosis of central auditory pathology in pediatrics when compared to absolute amplitude measures because these difference measures show significantly lower variability when examined across subjects.

Sensory profile of children with Central Auditory Processing Disorder (CAPD). / Perfil sensorial de crianças com Transtorno do Processamento Auditivo Central (TPAC).

PURPOSE: To analyze the sensory profile of children with auditory sensory processing disorder according to the Child Sensory Profile 2 and to verify potential associations between central auditory processing and sensory processing. METHODS: Sixty children from two public schools in the city of João Pessoa, state of Paraíba, were evaluated. All children had their cognitive skills tested and their socioeconomic and demographic information collected. The children's hearing, central auditory processing, and sensory processing were evaluated. SPSS Statistics version 25.0 was used for data analysis and the significant value adopted was 0.05. Descriptive analysis was performed using the central tendency method. The similarities among the test variables were measured by Student's t-test and Mann-Whitney U test. The effect size (ES) between the groups was measured by Cohen's d or Rosenthal's r coefficient. RESULTS: The average age of children with CAPD was 8.4 years, and their families had lower levels of income and education when compared to those without the disorder. Children with CAPD present more sensory differences than their peers with normative CAP. The Child Sensory Processing 2 results didn't show any statistic associations with central auditory processing, and the effect size was of moderate magnitude for the visual system. CONCLUSION: Children with CAPD have more sensory differences than their peers according to the normative results of the Child Sensory Profile 2. An association between sensory and central auditory processing was not observed, except for the visual system.

OBJETIVO: Analisar o perfil sensorial de crianças com TPAC, de acordo com o Child Sensory Profile 2 e verificar possíveis associações entre o PAC e o PS. MÉTODO: Foram avaliadas 60 crianças em idade escolar de duas escolas públicas de João Pessoa, PB. Todas realizaram triagem cognitiva, tiveram suas informações socioeconômicas colhidas e foram submetidas às avaliações audiológica, do processamento auditivo central e do processamento sensorial. A análise dos dados foi feita com o SPSS Statistics, versão 25.0, e o valor de significância adotado foi de 0,05. Foi realizada a análise descritiva com medidas de tendência central. A associação entre as variáveis foi medida pelos testes t de Student e U de Mann-Whitney. O tamanho do efeito da diferença entre os grupos foi medido pelo coeficiente d de Cohen ou r de Rosenthal. RESULTADOS: As crianças com TPAC tinham idade média de 8,4 anos, e suas famílias apresentaram renda e escolaridade inferior aquelas sem alteração do processamento auditivo. Foi observado que crianças com TPAC apresentam mais diferenças sensoriais que seus pares com PAC normal. Os resultados do Child Sensory Profile 2 não mostrou associação estatística com o processamento auditivo e a magnitude do tamanho do efeito entre as variáveis foi moderada para o sistema visual. CONCLUSÃO: Crianças com TPAC tem mais diferenças sensoriais que seus pares de acordo com o resultado normativo do Child Sensory Profile 2. Não foi observada associação entre o processamento sensorial e auditivo central, com exceção do sistema visual.

Evidence of Validity and Normative Values of a New Auditory Backward Masking Test.

There are still no valid, clinically feasible instruments to assess backward masking (BM), an auditory temporal processing (ATP) phenomenon. The aim of this study was to develop, standardize and present evidence of validity for a behavioral test for BM assessment. Young adults were submitted to a BM test (BMT), where they were asked to identify a 1000 Hz pure tone followed by a narrowband noise with interstimulus intervals of 0 to 400 ms and signal-to-noise ratio (SNR) between -20 and -30 dB. The correct response rate and target sound detection threshold were calculated, and the results compared with those of young adults with abnormal ATP tests and older adults. Diagnostic accuracy analyses were carried out. Young adults with normal ATP obtained an average correct response rate of 89 and 87% for SNR -20 and -30 dB, respectively, with average thresholds between 10 and 15 ms and no difference between the left and right ears. Results were more consistent at SNR -20 dB, and the best diagnostic accuracy was obtained for SNR -20 dB, with good specificity, but low sensitivity. Normative values were obtained for the BMT, which proved to be clinically feasible, with preliminary evidence of validity.

The Discourse Profile in Corticobasal Syndrome: A Comprehensive Clinical and Biomarker Approach.

The aim of this study was to characterize the oral discourse of CBS patients and to verify whether measures obtained during a semi-spontaneous speech production could differentiate CBS patients from controls. A second goal was to compare the performance of patients with CBS probably due to Alzheimer's disease (CBS-AD) pathology and CBS not related to AD (CBS-non-AD) in the same measures, based on the brain metabolic status (FDG-PET) and in the presence of amyloid deposition (amyloid-PET). Results showed that CBS patients were significantly different from controls in speech rate, lexical level, informativeness, and syntactic complexity. Discursive measures did not differentiate CBS-AD from CBS-non-AD. However, CBS-AD displayed more lexical-semantic impairments than controls, a profile that is frequently reported in patients with clinical AD and the logopenic variant of primary progressive aphasia (lvPPA). CBS-non-AD presented mainly with impairments related to motor speech disorders and syntactic complexity, as seen in the non-fluent variant of PPA.

Investigation of the neural discrimination of acoustic characteristics of speech sounds in normal-hearing individuals through Frequency-following Response (FFR). / Investigação da discriminação neural das características acústicas dos sons de fala em normo-ouvintes por meio do Frequency Following Response (FFR).

PURPOSE: 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.

OBJETIVO: Avaliar como as vias auditivas codificam e diferenciam as sílabas plosivas [ga],[da] e [ba], por meio do potencial evocado auditivo Frequency Following Response (FFR), nas crianças em desenvolvimento típico. MÉTODO: Vinte crianças (6-12 anos) foram avaliadas por meio do FFR para estímulos [ga],[da] e [ba]. Os estímulos foram compostos por seis formantes, sendo diferenciados na transição F2 e F3 (porção transiente). Os demais formantes foram idênticos nas três sílabas (porção sustentada). Foram analisadas latências de 16 ondas que compõe a porção transiente do estímulo (<70ms) e latências de 21 ondas da porção sustentada (90-160ms) nas respostas neurais obtidas para cada uma das sílabas. RESULTADOS: As respostas eletrofisiológicas registradas por meio do FFR demonstraram que as latências da porção transiente da resposta neural foram diferentes nas três silabas evocadas. Além disso, os valores de latência das ondas da porção transiente foram aumentando progressivamente, sendo [ga]<[da]<[ba]. Já na porção sustentada da resposta, não houve diferenças significantes nas latências das ondas que compõe essa porção. CONCLUSÃO: O FFR mostrou-se uma ferramenta eficiente na investigação da discriminação subcortical de diferenças acústicas dos sons de fala, uma vez que demonstrou diferentes resposta eletrofisiológica para três silabas evocadas. Na porção transiente (consoantes) foram observadas mudanças de latência e na porção sustentada (vogal) não houve diferenças entre as latências para os três estímulos. Esses resultados demonstram a capacidade neural de distinção entre características acústicas dos estímulos [ga],[da],[ba].

Executive Function and Sensory Processing in Dichotic Listening of Young Adults with Listening Difficulties.

Previous studies have suggested that varying attention demands in dichotic listening (DL) tasks might be a clinically feasible method to distinguish 'bottom-up' from 'top-down' deficits in listening. This study aims to investigate DL processing in adults with listening difficulties (LD). We assessed the performance of a listening difficulties group (LDG) (n = 24, mean age = 24, backward digit span = 4.0) and a control group (CG) (n = 25, mean age = 29.2, backward digit span = 6.4) in DL tests involving non-forced and both right and left-forced attention. The results indicated an overall significantly worse performance of LDG compared to the CG, which was greater for forced-left condition. This same result was observed when controlling for working memory (WM) variance. Both groups presented an overall right ear advantage with no difference in terms of the magnitude of advantage. These results indicate that LD presented by the LDG might be due to a combination of sensory and cognitive deficits, with emphasis on the cognitive component. However, the WM, although impaired in the LDG group, was not the main factor in segregating both groups. The role of the additional cognitive processes such as inhibitory control in LD is discussed.

Dichotic sentence identification test in Portuguese: a study in young adults.

INTRODUCTION: Among the currently-applied auditory processing tests, dichotic listening tests have been widely used, since they allow investigating the hemispheric and inter-hemispheric function and their respective skills to process the received auditory information. OBJECTIVE: To obtain normality reference measures with the new dichotic sentence identification test in right-handed adults with normal hearing. METHODS: Quantitative, observational, cross-sectional study. 72 subjects were assessed, aged 19-44 years, right-handed, with normal hearing, without hearing complaints. The dichotic sentence identification test consists of different lists of sentences, which were combined two by two and presented at the same time, using earphones in both ears, at 50dB Sensation Level. The test was applied in four stages: training of the 3 stages, free attention, right and left directed attention, thus evaluating different auditory skills. RESULTS: In the free attention task, the average percentage of correct answers in the right ear was 93.59% and in the left ear 86.06%, with a statistically significant difference between the ears, with an advantage for the right ear. In the directed attention task, the average percentage of correct answers was 99.37% in the right ear and 98.8% in the left ear, with no statistical difference between the ears. CONCLUSION: It is suggested, as a normality reference for the stage of free attention, 90%-100% for correct answers for the right ear and for the left ear, from 80% to 100%. When there is asymmetry between the ears, differences of up to 20% are expected, with an advantage for the right ear For the directed attention stage, the expected normality reference values ​​are 100% for the right ear and for the left ear, with no asymmetry between the ears; however, if it occurs, a difference of 10% is expected between the ears, with an advantage for the right ear.

Language in corticobasal syndrome: a systematic review.

Language is commonly impacted in corticobasal syndrome (CBS). However, the profile and type of language assessment in CBS are poorly studied. OBJECTIVE: To identify language impairments in CBS. METHODS: A search was performed in the Medline/PubMed database, according to the PRISMA criteria, using the keywords "corticobasal syndrome" OR "corticobasal degeneration" AND "language". Articles on CBS covering language assessment that were written in English were included, with no constraints on the publication date. RESULTS: A total of 259 articles were found and 35 were analyzed, consisting of 531 participants. Twenty-eight studies showed heterogeneous language deficits and seven mentioned nonfluent primary progressive aphasia. The most used tests were the Western Aphasia Battery (8 studies) and the Boston Naming Test (8 studies). CONCLUSION: It was not possible to identify a unique linguistic profile in CBS.

A linguagem encontra-se comumente alterada na síndrome corticobasal (SCB). No entanto, o perfil e a forma de avaliação da linguagem na SCB são pouco estudados. OBJETIVO: identificar as alterações de linguagem na SCB. MÉTODO: Realizou-se uma busca na base de dados Medline/PubMed, com as palavras-chave "síndrome corticobasal" OU "degeneração corticobasal" E "linguagem". Artigos sobre SCB envolvendo avaliação de linguagem, escritos em inglês, foram incluídos, sem restrição de data de publicação. RESULTADOS: Foram encontrados 259 artigos, e 35 estudos foram analisados, abrangendo 531 sujeitos. Um total de 28 estudos mostraram déficits heterogêneos de linguagem, e sete mencionaram afasia progressiva primária não-fluente. Os testes mais utilizados foram Western Aphasia Battery (8 estudos) e o Teste de Nomeação de Boston (8 estudos). CONCLUSÃO: Não foi possível identificar um perfil linguístico único em pacientes com SCB.

Performance of public and private school students in auditory processing, receptive vocabulary, and reading comprehension.

PURPOSE: To characterize the performance of 5th grade students from public and private elementary schools in auditory processing, receptive vocabulary, and reading comprehension. METHODS: The study sample was composed of 34 Elementary School (5th grade) students: 16 from public school (PubG) and 18 from private school (PrivG), whose parents and teachers responded to questionnaires on their language development, socioeconomic level, and academic performance. The auditory skills of figure-ground, association between auditory and visual stimuli, figure-ground for linguistic sounds, binaural integration, temporal ordering, and temporal resolution were assessed using the following auditory behavioral instruments: Pediatric Speech Intelligibility (PSI) test, Dichotic Digits Test (DDT), Auditec® Frequency Pattern Test (FPT), and Gaps-in-Noise (GIN) test. Receptive vocabulary and reading comprehension were evaluated using the TVF-usp and PROLEC tests, respectively. RESULTS: Statistically significant differences were observed between the socioeconomic level of students in both schools. Although the results obtained in the applied tests were within the reference values in both groups, there was a tendency to higher scores in the PrivG. Differences between the groups were also verified in the DDT and FPT. Values similar to normality were obtained in the temporal resolution and reading comprehension assessments. On the vocabulary test, most school children in the PrivG were concentrated in the 'high' and 'middle' categories, whereas those in the PubG were in the 'middle' and 'low' categories. CONCLUSION: There are differences in performance between students from private and public schools. Public school children presented right ear advantage in the dichotic task, whereas private school children showed more efficient mechanisms and strategies regarding auditory stimuli for the tasks of binaural integration, temporal ordering, and interhemispheric transfer. Temporal resolution reached values expected for the adult population in both groups. Better vocabulary performance was observed in the most economically favored children. Elementary School (5th grade) students from both school networks present developed reading.

GIN Test: A Meta-Analysis on Its Neurodiagnostic Value.

PURPOSE: A meta-analysis was conducted to evaluate how effective the Gaps-in-Noise (GIN) test is in separating populations who are and who are not at risk of having neurological damage related to the central auditory nervous system (CANS). This was investigated by asking three specific questions: (1) Does ear and side of lesion have an effect over the individual's performance? (2) How large is the difference in performance between control and neurological groups? (3) What are the diagnostic indices related to the GIN test? DATA COLLECTION AND ANALYSIS: A literature review was performed between April 2016 and April 2017. The eligibility criteria for inclusion were as follows: (1) studies that used the GIN test as an outcome measure, (2) studies that included adult participants who either had confirmed lesions or were at risk of having lesions to the CANS or related regions, and (3) studies that had a neurologically normal control group. From relevant studies that met eligibility criteria, information regarding study design, participants, lesion details and origins, use of additional assessments, GIN performance scores for both control (CTRL) and neurological (NRLG) groups, GIN cutoff scores and proportion of individuals with normal and abnormal performances were all included. RESULTS: Nine studies were included, totaling 221 participants in NRLG (stroke = 90, epilepsy = 67, and blast exposure [BLST] = 64) and 262 in CTRL (Stroke = 106, Epilepsy = 98, and BLST = 58). No significant ear effects related to side of lesion were observed for the GIN test in neurological patients nor were there significant ear differences for normal individuals with symmetrically normal hearing. The GIN demonstrated consistency among different neurological populations, presented good sensitivity and specificity rates, and was overall accurate in discriminating between participants with neuroauditory lesions from neurologically normal individuals. CONCLUSIONS: The GIN is thus a clinically effective measure that provides insight into the CANS integrity and may aid in clinical diagnosis by distinguishing between populations who are and who are not at risk of having neurological damage affecting the CANS.

The Role of Phonological, Auditory Sensory and Cognitive Skills on Word Reading Acquisition: A Cross-Linguistic Study.

Despite considerable evidence regarding the influence of orthography on reading processing, the impact of orthographic depth on reading predictors remains unclear. In addition, it also remains unknown the role of the orthography in the influence of auditory temporal processing and attention skills on word reading skills. The current study investigates the word reading predictors in a group of British and Brazilian children with typical development considering phonological, auditory sensory, short-term memory, and sustained attention skills. Rhyme and Alliteration skills predicted word reading in both groups; however, the correlation in the British group was more robust. Short-term memory was also correlated with reading in both groups; however, it was a significant word reading predictor only in the British group. The auditory sensory was not directly correlated with word reading in either group; however, it was involved with Rhyme and Alliteration performance only in the British group. Those results were discussed considering the complexity of the phonological structure and opaque orthography in English when compared to Portuguese, which indicates that the less transparent the orthography, the higher the importance of factors such as phonological awareness, short-term memory, and to some extent, auditory sensory processing skills on word reading acquisition. Those results emphasize the need to consider orthography and phonological features of a particular language when developing a reading assessment and treatments.

The influence of oral language environment on auditory development.

OBJECTIVE: 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.

The effectiveness of an auditory temporal training program in children who present voiceless/voiced-based orthographic errors.

INTRODUCTION: Studies on children's written production of the Brazilian Portuguese have shown that one of the most frequent phonological-based orthographic errors is the one related to voiceless/voiced phonemes. Children who make this type of error may have auditory temporal processing disorders, which can harm the perception of phonemes with similar characteristics. AIM: Verify the effectiveness of an auditory temporal training program based on activities adapted from the software Fast ForWord in the auditory temporal processing, i.e. the temporal ordering skill, and in reducing voiceless/voiced-based orthographic errors and the frequency of occurrence of these errors in the written production of the children. METHOD: Twenty-five children participated on this study. They were divided in two groups: experimental group consisting of 16 participants, who engaged in the auditory temporal training activities; and a placebo group consisting of nine participants, who engaged in passive visual activities. The behavioral measures applied in the pre-training evaluation, post-training and placebo evaluations were: i) auditory skill of temporal ordering by the Pitch Pattern Sequence Test; and ii) analysis of the amount of voiceless/voiced-based orthographic errors and the frequency of occurrence of these errors by the use of dictation. RESULTS: No statistically significant differences were found concerning the placebo group in the pre-training and post-training evaluations, in all evaluation measures. However, statistically significant differences were found in the pre-training and post-training evaluations for the pitch pattern sequence test concerning the experimental group. These differences were specifically related to a reduction of the errors regarding fricative graphemes, and the frequency of occurrence of plosive and fricative graphemes. CONCLUSIONS: The auditory temporal training program was effective in improving the temporal ordering skill and reducing errors in the writing of children who made voiceless/voiced-based orthographic errors.
