Abstract Objective: The present study aimed to determine the fidelity, reliability, and internal validity of the APDQ when translated from English to Brazilian-Portuguese language. Methods: The first phase included the APDQ translation into Brazilian-Portuguese including forward translation, translation assessment and back-translation in a group of 10 students. The second phase involved establishing the internal consistency and reliability of the APDQ Brazilian-Portuguese version. Data was collected from 66 students without any risk factor for auditory processing disorder. Subjects were divided into a younger group (7–10yrs) and an older group (11–17yrs). Results: All items showed appropriate quality in terms of translation. In determining internal consistency, Cronbach’s alpha in subscales of auditory processing, attention and language was found to be 0.93, 0.85 and 0.74, respectively. Intraclass Correlation Coefficient for total score was 0.95, ensuring a strong test-retest reliability. Conclusion: The Brazilian-Portuguese version of the APDQ has favorable translation quality, internal validity and reliability. It is now ready for continued study as a differential screening tool for 7- to 17-year-old Brazilian children with listening difficulties who are at risk for auditory processing disorder, attention deficits and language learning challenges.

Abstract Introduction Knowledge about the positive effects that music and dance bring, in its various forms, to the healthy human brain, is important not only in the context of basic neuroscience but may also strongly affect practices in neurorehabilitation. Objective To verify the relationship between hearing and movement and, specifically, to analyze the interference of professional dance practice and formal musical training in the magnitude of the vestibule-cervical and vestibular reflexes. Method The sample consisted of 92 subjects, aged between 18 and 35 years old, 31 professional musicians, 31 ballet dancers, and 30 control subjects. Only subjects with normal hearing sensitivity were included. Cervical vestibular evoked myogenic potential (cVEMP) was recorded in the sternocleidomastoid muscle, and ocular vestibular evoked myogenic potential (oVEMP) was recorded in the lower oblique muscle of the eye, using tone-bursts (500Hz). Analysis of variance (ANOVA) or Kruskall-Wallis tests were performed. Results The cVEMP presented earlier and higher amplitude waves when recorded in the group of dancers, with a significant difference between all tested groups for latency and amplitude of the N23 wave; the comparison was restricted between dancers and control groups, with no difference between ballet dancers and musicians. The N1 wave of the oVEMP presented lower latencies in dancers than in musicians and controls (p= 0.001). No significant differences were found between the groups for the P1 wave. Conclusion Greater magnitudes of vestibule-cervical reflex responses and faster vestibule-ocular reflex responses were observed in dancers. Dance practice provides greater development of the vestibular system, but musical training also contributes to the magnitude of these responses.

Abstract Introduction Nowadays, there is no consensus on whether central auditory processing disorder is a primary or a secondary deficit to other cognitive deficits. A better understanding of the association between cognitive functions and central auditory skills may help elucidate this dilemma. Objective To investigate possible associations between auditory abilities and cognitive functions in schoolchildren. Methods Fifty-eight schoolchildren, aged between 8 years and 0 months old and 11 years and 11 months old, who underwent the following tests: masking level difference, gaps in noise, pitch pattern sequence test, dichotic digits test, sustained auditory attention ability test, Wechsler intelligence scale for children - IV, junior Hayling test, five digits test, and behavior rating inventory of executive function. Results Significant correlations were found between the hearing ability of temporal resolution and executive functions, temporal ordering/sequencing, binaural integration and separation, and sustained auditory attention, operational memory, inhibitory control, and cognitive flexibility; binaural integration was also associated with intelligence. The statistically significant positive correlation found between the ability of binaural interaction and the components of emotional control and behavior regulation of the behavior rating inventory of executive function was unexpected. Conclusion The associations identified reinforce the complexity of the tasks involved in the evaluation of central auditory processing and the need for multidisciplinary evaluation for the differential diagnosis of auditory processing disorder. Confirmation of the presence or absence of comorbidities between different disorders allows directing the therapeutic behaviors and reducing the impact of possible auditory and/or cognitive deficits in the different daily life situations of children.

RESUMO Objetivo verificar e comparar a ocorrência e magnitude do efeito inibitório da via auditiva eferente em crianças e adolescentes com processamento auditivo normal e alterado, identificando um valor de corte para uso na prática clínica. Métodos estudo prospectivo, com amostra composta por 30 crianças de 7 a 14 anos, sendo 15 com avaliação de processamento auditivo normal (grupo controle) e 15 com processamento auditivo alterado (grupo estudo). Ambos os grupos foram submetidos à anamnese e avaliados por meio dos testes de emissões otoacústicas evocadas por estímulos transientes na ausência e presença de ruído contralateral, avaliação audiológica básica e de processamento auditivo. Resultados houve menor ocorrência do efeito inibitório da via eferente no grupo estudo (p-valor=0,038). Os valores médios obtidos no grupo controle foram 0,71 na orelha direita e 0,87 na orelha esquerda e no grupo estudo, 0,55 na orelha direita e 0,41 na orelha esquerda. Os grupos controle e estudo diferiram de modo significativo na orelha esquerda. Conclusão houve redução do efeito inibitório da via eferente em crianças e adolescentes com transtorno de processamento auditivo, sugerindo alteração funcional do sistema eferente olivococlear medial. O valor que separou as crianças com e sem alteração do sistema eferente foi de 0,55 dB na prática clínica, com 70% de sensibilidade e 66,7% de especificidade.

ABSTRACT Purpose Verify and compare the occurrence and magnitude of the inhibitory effect of the efferent auditory pathway in children and adolescents with normal and auditory processing disorder, identifying a cutoff value to use in clinical settings. Methods A prospective study, with a total sample of 30 children aged 7 to 14 years, half with normal auditory processing assessment (Control Group) and the other half with auditory processing disorder (Study Group). Both groups were submitted to anamnesis and evaluated using the otoacoustic emissions tests evoked by transient stimuli in the absence and presence of contralateral noise, basic audiological evaluation and auditory processing. Results The study group presented a lower occurrence of the inhibitory effect of the efferent pathway when compared to the control group (p value=0.038). The mean values obtained for the control group were 0.71 in the right ear and 0.87 in the left ear and for the study group, 0.55 in the right ear and 0.41 in the left ear. The two groups showed a statistically significant difference for the left ear. Conclusion There was a reduction in the inhibitory effect of the efferent pathway in children and adolescents with auditory processing disorder, suggesting a functional change in the medial olivocochlear efferent system. In this study, the cutoff value of 0.55 dB separated children with and without alteration of the efferent system with 70% sensitivity and 66.7% specificity.

RESUMO Objetivo: investigar o reconhecimento auditivo da fala intermitente em função de diferentes taxas de modulação e em função da idade. Métodos: participaram do estudo vinte jovens, vinte adultos de meia idade, e dezesseis idosos, todos com limiares auditivos iguais ou menores que 25 dB NA até a frequência de 4000 Hz. Os participantes foram submetidos a testes de reconhecimento da fala intermitente apresentada em três condições de modulação: 4 Hz, 10 Hz e 64 Hz. Percentuais de acerto foram comparados entre grupos etários e taxas de modulação. Para a investigação do efeito da taxa de modulação foi realizada ANOVA e testes Post Hoc, enquanto para a investigação do efeito da idade, utilizou-se o modelo de regressão linear misto (p<0,001). Resultados: sobre o efeito da idade, os dados mostram diferença significante entre jovens e idosos, e entre adultos de meia idade e idosos. Sobre o efeito da taxa de modulação, os índices de acerto da taxa mais lenta (4Hz) foram significantemente menores nos três grupos etários. Conclusão: foi verificado um efeito da idade no reconhecimento da fala intermitente: idosos apresentaram maior dificuldade. Percebeu-se também um efeito de taxa de modulação nos três grupos etários: quanto maior a taxa, melhor o desempenho.

ABSTRACT Purpose: to investigate the auditory recognition of intermittent speech in relation to different modulation rates and ages. Methods: 20 young people, 20 middle-aged adults, and 16 older adults, all of them with auditory thresholds equal to or lower than 25 dB HL up to the frequency of 4000 Hz. The participants were submitted to intermittent speech recognition tests presented in three modulation conditions: 4 Hz, 10 Hz, and 64 Hz. The percentages of correct answers were compared between age groups and modulation rates. ANOVA and post hoc tests were conducted to investigate the modulation rate effect, and the mixed linear regression model (p < 0.001). Results: regarding the age effect, the data showed a significant difference between young people and older adults, and between middle-aged and older adults. As for the modulation rate effect, the indexes of correct answers were significantly lower at the slower rate (4 Hz) in the three age groups. Conclusion: an age effect was verified on intermittent speech recognition: older adults have greater difficulty. A modulation rate effect was also noticed in the three age groups: the higher the rate, the better the performance.

OBJECTIVES: We aimed to evaluate the effectiveness of a binaural auditory training program with vocal duets by comparing skills through outcomes from behavioral and electrophysiological assessment instruments at three moments: before the intervention, moment one (M1); immediately after training, moment two (M2); and 3 months after, moment three (M3). METHODS: This interventional, longitudinal, prospective, and uncontrolled study was approved by our Research Ethics Committee. Binaural auditory training with vocal duets (ATVD) was applied in 10 adults with normal audiometric thresholds and auditory processing disorders. ATVD used four different vocals of a public domain song sung in a cappella as stimuli. Participants were asked to register any perceived difference in frequency for each syllable of the song during 30-minute sessions twice a week. The number of sessions required ranged from 12 (6 hours) to 20 (10 hours). RESULTS: Regarding behavioral tests, the dichotic consonant-vowel test showed significant evidence of an improved advantage in the left ear (LE) in the non-forced condition and a significant reduction in the number of errors at M2 and M3 in the forced left condition. The speech-in-noise test and frequency pattern test showed a significant reduction in impaired results at M2 and M3. Electrophysiological results showed a significant increase in the LE amplitude in the P3 long-latency auditory evoked potentials test, as well as a decrease in the auditory brainstem response test (III-V and I-V inter-peak latencies in the right ear and wave I and I-III inter-peak latencies in LE). CONCLUSION: The effectiveness of ATVD was evidenced, and the results were maintained after 3 months.

OBJECTIVE: To evaluate the relationship between cognitive performance and long-latency auditory evoked potentials in an elderly population. METHODS: The sample consisted of adults between 20 and 58 years of age and elderly adults between 60 and 70 years of age. The screening procedures adopted were an inspection of the external auditory canal, tonal and vocal audiometry, tympanometry, brain stem auditory evoked potential, the Montreal Cognitive Assessment test, and long-latency auditory evoked potential. RESULTS: The latency and amplitude values of cortical components by age group showed significant differences under the following conditions: (i) signals evoked by the speech stimulus /da/ and by the pure-tone stimulus at 2,000 Hz for the N2 amplitude (p=0.008 and p=0.001, respectively) , which were both higher for adults, and (ii) signals evoked by the speech stimulus /da/ for N1 latency (p=0.018) and by the pure-tone stimulus at 2,000 Hz for P2 latency (p=0.017), which were both higher in the elderly population. The cognitive component (P300) showed a significant difference when evoked by speech stimuli, with higher latency in the elderly population (p=0.013). When correlated with cognitive processes, the latency and amplitude of cortical potentials showed direct and medium-strength correlations between abnormal scores obtained on the Montreal Cognitive Assessment test and P2 amplitude (p<0.001 and r=0.452). CONCLUSION: There is a relationship between long-latency potentials and cognitive performance in the elderly, which was observed by the increase in the P2 amplitude and the impairment of the process of sound decoding.

RESUMO Objetivo Verificar a efetividade do treinamento auditivo acusticamente controlado em pessoas com distúrbio do processamento auditivo central e perda auditiva unilateral de grau severo a profundo. Métodos Participaram do estudo 16 indivíduos, de 13 a 21 anos de idade, diagnosticados com perda auditiva unilateral de grau severo a profundo e transtorno do processamento auditivo central, divididos em dois grupos, com oito indivíduos cada, pareados por idade, sexo e escolaridade: grupo estudo, submetido ao programa de treinamento auditivo acusticamente controlado, em oito sessões, realizadas uma vez por semana; grupo comparação, que não foi submetido a nenhum tipo de intervenção. Ao final de oito semanas, os grupos foram reavaliados quanto ao potencial evocado auditivo de longa latência (P300) e quanto às habilidades auditivas alteradas, observadas nos testes Localização Sonora, Identificação de Sentenças Sintéticas, Fala no Ruído e Randon Gap Detection Test. Resultados Não houve influências do lado da perda auditiva na avaliação inicial, para nenhum dos grupos. Na avaliação final, verificou-se, somente no grupo estudo, aprimoramento de todas as habilidades auditivas, diminuição da latência e aumento da amplitude no P300. Indivíduos com perda auditiva à direita apresentaram maior aumento da amplitude do P300. Não foram observadas modificações no grupo comparação. Conclusão O treinamento auditivo acusticamente controlado foi eficaz, pois possibilitou o aprimoramento das habilidades auditivas e a modificação na atividade neurobiológica quanto à velocidade de processamento auditivo. Sugere-se essa opção de intervenção em pessoas com transtorno do processamento auditivo central e perda auditiva unilateral.

ABSTRACT Purpose To verify the effectiveness of the auditory training acoustically controlled in people with central auditory processing disorders and unilateral hearing loss from severe to profound. Methods 16 individuals between the age of 13 to 21 diagnosed with unilateral hearing loss from severe to profound and central auditory process disorder has participated in this study, individuals were divided into two groups, consisting of eight individuals each, paired by age, sex and education. Eight of them – Experimental Group - underwent an individual Acoustically Controlled Auditory Training program consisting of eight sessions accomplished once a week. The remaining individuals - Control Group – there were no intervention. At the end of eight weeks, both groups were reassessed for Long Latency Auditory Evoked Potential (P300), and altered hearing abilities on the Sound Localization test, Synthetic Sentence Identification, Speech in Noise and Random Gap Detection Test. Results There were no influences of the hearing loss side in the initial assessment for any of the groups. In the final assessment there was an improvement in all abilities, decreased latency and increased amplitude in P300 only Experimental Group. Individuals with hearing loss on the right showed a greater increase in P300 amplitude. There were no changes in the Control Group. Conclusion The acoustically controlled auditory training was effective because it allowed an improvement of the auditory abilities and a modification in the neurobiological activity in relation to the auditory processing speed. This option it is suggested for intervention in people with a central auditory processing disorder and hearing loss.

RESUMO Objetivo: analisar as habilidades auditivas, de linguagem, motoras e sociais de crianças e propor uma triagem do desenvolvimento infantil. Métodos: participaram 129 pré-escolares, de ambos os sexos, com idades entre três e seis anos, matriculadas em instituições de educação infantil e 25 educadores do ensino infantil oriundos de instituições públicas e particulares. Todas as crianças com curvas timpanométricas tipo A e presença de reflexos acústicos. Nas crianças, aplicou-se o teste de desenvolvimento neuropsicomotor, Denver II, e a avaliação da localização sonora e da ordenação temporal de três sons verbais e não verbais. Com as educadoras, foi aplicado a Escala SAB. Resultados: verificou-se que a grande maioria dos participantes com SAB normal apresentaram habilidades auditivas ou Denver II normal; enquanto no grupo de SAB alterado, grande parte dos participantes apresentou alteração no Denver II ou nos testes de habilidades auditivas. Foi constatado, ainda, que parte das crianças com Denver II normal foram apontados, pelos educadores, como com comportamento inadequado no SAB. Conclusão: a combinação entre os achados do Denver II, de testes auditivos de localização sonora e ordenação temporal e a Escala SAB são úteis na caracterização do desenvolvimento infantil, assim, recomenda-se o uso dos três instrumentos como triagem.

ABSTRACT Purpose: to analyze the hearing, language, motor and social skills of children and propose a screening of child development. Methods: 129 preschool children of both sexes, aged between three and six years old, enrolled in educational institutions and 25 teachers of kindergarten from public and private institutions, with no history of hearing disorders, with type A tympanometric curves and the presence of acoustic reflexes participated. For the children, the neuropsychomotor test, Denver II, and the evaluation of sound localization and temporal ordination of three verbal and non-verbal sounds were applied. For the educators responsible for the children, the Scale of Auditory Behaviors (SAB), was used. Results: most participants with normal SAB presented hearing abilities or standard Denver II; while in the amended SAB group, most participants presented alterations in Denver II or in the auditory abilities tests. It was found, also, that part of the children with standard Denver II were pointed, by the educators, as misbehaving in SAB. Conclusion: the combination of the findings of the Denver II, hearing tests of sound localization and temporal ordination and the SAB Scale is useful in the characterization of child development and, thus, the use of these three instruments for screening in this age group is recommended.

Abstract Introduction Long latency auditory evoked potentials, especially P300, have been used for clinical evaluation of mental processing. Many factors can interfere with Auditory Evoked Potential - P300 results, suggesting large intra and inter-subject variations. Objective The objective of the study was to identify the reliability of P3 components (latency and amplitude) over 4-6 weeks and the most stable auditory stimulus with the best test-retest agreement. Methods Ten normal-hearing women participated in the study. Only subjects without auditory processing problems were included. To determine the P3 components, we elicited long latency auditory evoked potential (P300) by pure tone and speech stimuli, and retested after 4-6 weeks using the same parameters. We identified P300 latency and amplitude by waveform subtraction. Results We found lower coefficient of variation values in latency than in amplitude, with less variability analysis when speech stimulus was used. There was no significant correlation in latency measures between pure tone and speech stimuli, and sessions. There was a significant intrasubject correlation between measures of latency and amplitude. Conclusion These findings show that amplitude responses are more robust for the speech stimulus when compared with its pure tone counterpart. The P300 indicated stability for latency and amplitudemeasures when the test-retest was applied. Reliability was higher for amplitude than for latency, with better agreement when the pure tone stimulus was used. However, further research with speech stimulus is needed to clarify how these stimuli are processed by the nervous system.

RESUMO Objetivo Investigar o perfil das habilidades auditivas de fechamento e figura-fundo e fatores relacionados à atenção, comunicação e saúde de controladores de tráfego aéreo (CTA) de aproximação de aeronaves e comparar com os de outros profissionais civis e militares. Método Participaram 60 adultos com limiares audiométricos normais reunidos em dois grupos, pareados por idade e gênero: o grupo estudo formado por 30 profissionais do Controle de Aproximação de aeronaves e o controle, por 30 outros servidores civis e militares. Todos foram submetidos a perguntas relacionadas à atenção, comunicação e saúde e ao Teste de Fala com Ruído e de Identificação de Sentenças Sintéticas em escuta monótica (SSI) para avaliar fechamento e figura-fundo, respectivamente. Foram usados testes estatísticos não paramétricos e análise de regressão logística. Resultados O CTA autorreferiu maior cansaço/esgotamento e estresse e obteve melhor desempenho do que o grupo controle em figura-fundo e semelhante em fechamento. Foi observado que ocorreu uma probabilidade de ser CTA para o estresse em 5,59 vezes e para identificação de sentenças em escuta monótica à orelha direita de 1,24. Conclusão Fechamento e autorrelato de dificuldades de saúde, comunicação e atenção na maioria das questões foram similares em ambos os grupos. Figura-fundo foi significativamente melhor em CTA. Autorreferência de estresse e desempenho à orelha direita no SSI foram preditores significantes do indivíduo ser do CTA.

ABSTRACT Purpose To investigate the auditory skills of closure and figure-ground and factors associated with health, communication, and attention in air traffic controllers, and compare these variables with those of other civil and military servants. Methods Study participants were sixty adults with normal audiometric thresholds divided into two groups matched for age and gender: study group (SG), comprising 30 air traffic controllers and control group (CG), composed of 30 other military and civil servants. All participants were asked a number of questions regarding their health, communication, and attention, and underwent the Speech-in-Noise Test (SIN) to assess their closure skills and the Synthetic Sentence Identification Test - Ipsilateral Competitive Message (SSI-ICM) in monotic listening to evaluate their figure-ground abilities. Data were compared using nonparametric statistical tests and logistic regression analysis. Results More individuals in the SG reported fatigue and/or burnout and work-related stress and showed better performance than that of individuals in the CG for the figure-ground ability. Both groups performed similarly and satisfactorily in the other hearing tests. The odds ratio for participants belonging in the SG was 5.59 and 1.24 times regarding work-related stress and SSI-ICM (right ear), respectively. Conclusion Results for the variables auditory closure, self-reported health, attention, and communication were similar in both groups. The SG presented significantly better performance in auditory figure-ground compared with that of the CG. Self-reported stress and right-ear SSI-ICM were significant predictors of individuals belonging to the SG.

RESUMO Objetivos: Verificar a eficácia do treinamento auditivo em tarefa dicótica e comparar as respostas da habilidade treinada com as repostas das habilidades não treinadas, após quatro e oito semanas. Métodos: 19 indivíduos, de 12 a 15 anos foram submetidos a um treinamento auditivo baseado no DIID e organizados em 8 sessões, com duração de 50 minutos por sessão. Realizaram a avaliação do processamento auditivo em três momentos: pré-intervenção, pós-intervenção na metade e no final do treinamento. Os dados desta avaliação foram analisados por grupo de distúrbio de acordo com as alterações nos processos auditivos avaliados: atenção seletiva e processamento temporal. Em cada um deles, denominado Grupo atenção seletiva (GAS) e Grupo processamento temporal (GPT), e em ambos os processos: Grupo atenção seletiva e processamento temporal (GASPT). Resultados: O treinamento melhorou a habilidade treinada e a não treinada de fechamento, normalizando todos os indivíduos. As habilidades não treinadas de resolução e ordenação temporal não atingiram a normalidade no GASPT e GPT. Conclusão: Os indivíduos alcançaram a normalidade para a habilidade treinada de figura-fundo e paraa não treinada de fechamento. Já as habilidades não treinadas de resolução e ordenação temporal melhoraram em alguns indivíduos, porém não atingiram a normalidade.

ABSTRACT Purposes: To evaluate the effectiveness of auditory training in dichotic task and to compare the responses of trained skills with the responses of untrained skills, after 4-8 weeks. Methods: Nineteen subjects, aged 12-15 years, underwent an auditory training based on dichotic interaural intensity difference (DIID), organized in eight sessions, each lasting 50 min. The assessment of auditory processing was conducted in three stages: before the intervention, after the intervention, and in the middle and at the end of the training. Data from this evaluation were analyzed as per group of disorder, according to the changes in the auditory processes evaluated: selective attention and temporal processing. Each of them was named selective attention group (SAG) and temporal processing group (TPG), and, for both the processes, selective attention and temporal processing group (SATPG). Results: The training improved both the trained and untrained closing skill, normalizing all individuals. Untrained solving and temporal ordering skills did not reach normality for SATPG and TPG. Conclusions: Individuals reached normality for the trained figure-ground skill and for the untrained closing skill. The untrained solving and temporal ordering skills improved in some individuals but failed to reach normality.

Resumo:OBJETIVO:avaliar a habilidade auditiva de resolução temporal e de identificação de sentenças com mensagem competitiva em dançarinos.MÉTODOS:trata-se de um estudo prospectivo em que foram avaliados 40 indivíduos distribuídos em dois grupos: grupo 1 (dançarinos) e grupo 2 (não-dançarinos). Os instrumentos de avaliação do processamento auditivo utilizados foram: teste Gaps-in-noise (GIN) e teste de reconhecimento de sentenças na presença de mensagem competitiva (SSI).RESULTADOS:os limiares de gap de ambos os grupos variaram de 3 a 6 ms e não demostraram diferença estatisticamente significante na comparação entre os grupos. Houve diferença estatisticamente significante ao comparar a porcentagem de identificação de gaps entre os dois grupos, sendo que o grupo de dançarinos apresentou média maior que o grupo de não dançarinos.O teste de reconhecimento de frases em escuta monótica (rel -10dB) mostrou resultados que variaram de 50% até 100% para o grupo de dançarinos e de 40% até 100% para o de não - dançarinos. A idade de início da dança (antes ou depois dos sete anos) não influenciou no desempenho dos testes estudados. Não houve correlação entre as variáveis dos achados obtidos nos testes estudados no grupo de dançarinos considerando o tempo de dança.CONCLUSÃO:a dança influenciou positivamente a habilidade auditiva de resolução temporal, pois o grupo de dançarinos apresentou desempenho melhor do que o grupo de não-dançarinos. A dança parece não ter influenciado a habilidade auditiva de figura-fundo.

Abstract:PURPOSE:to assess the ability of auditory temporal resolution and identification of sentences with competitive message in dancers.METHODS:this is a prospective study that evaluated 40 subjects distributed in two groups: group 1 (dancers) and group 2 (non-dancers). The assessment instruments in the auditory processing were Gaps-in-noise test (GIN) and Synthetic Sentence Identification test (SSI).RESULTS:the gap thresholds of both groups ranged 3-6 ms and did not show a statistical significant difference when comparing the groups. There was a statistically significant difference when comparing the percentage of identifying gaps between the two groups, and the group of dancers had a mean higher than the group of non- dancers. The sentence recognition test in monotic (rel -10dB) showed results ranging from 50% to 100% for the group of dancers and 40% up to 100% for non-dancers. The dance early age (before or after seven years) did not influence the performance of the studied tests. There was no correlation between the variables from findings of tests studied in considering the group of dancers at dance time.CONCLUSION:dance positively influenced the auditory ability of temporal resolution, since the group of dancers had performed better than the non-dancers group. The dance did not influence the auditory ability of figure-ground.
