The general aim of this thesis was to test the effects of paralinguistic (emotional) and prior contextual (topical) cues on perception of poorly specified visual, auditory, and audiovisual speech. The specific purposes were to (1) examine if facially displayed emotions can facilitate speechreading performance; (2) to study the mechanism for such facilitation; (3) to map information-processing factors that are involved in processing of poorly specified speech; and (4) to present a comprehensive conceptual framework for speech perception, with specification of the signal being considered. Experi¬mental and correlational designs were used, and 399 normal-hearing adults participated in seven experiments. The main conclusions are summarised as follows. (a) Speechreading can be facilitated by paralinguistic information as constituted by facial displayed emotions. (b) The facilitatory effect of emitted emotional cues is mediated by their degree of specification in transmission and ambiguity as percepts; and by how distinct the perceived emotions combined with topical cues are as cues for lexical access. (c) The facially displayed emotions affect speech perception by conveying semantic cues; no effect via enhanced articulatory distinctiveness, nor of emotion-related state in the perceiver is needed for facilitation. (d) The combined findings suggest that emotional and topical cues provide constraints for activation spreading in the lexicon. (e) Both bottom-up and top-down factors are associated with perception of poorly specified speech, indicating that variation in information-processing abilities is a crucial factor for perception if there is paucity in sensory input. A conceptual framework for speech perception, comprising specification of the linguistic and paralinguistic information, as well as distinctiveness of primes, is presented. Generalisations of the findings to other forms of paralanguage and language processing are discussed.

We develop in this thesis a computational model of music expectation, which may be one of the most important aspects in music listening. Many phenomenons related to music listening such as preference, surprise or emo- tions are linked to the anticipatory behaviour of listeners. In this thesis, we concentrate on a statistical account to music expectation, by modelling the processes of learning and predicting spectro-temporal regularities in a causal fashion. The principle of statistical modelling of expectation can be applied to several music representations, from symbolic notation to audio signals. We first show that computational learning architectures can be used and evaluated to account behavioral data concerning auditory perception and learning. We then propose a what/when representation of musical events which enables to sequentially describe and learn the structure of acoustic units in musical audio signals. The proposed representation is applied to describe and anticipate timbre features and musical rhythms. We suggest ways to exploit the properties of the expectation model in music analysis tasks such as structural segmentation. We finally explore the implications of our model for interactive music applications in the context of real-time transcription, concatenative synthesis, and visualization. / Esta tesis presenta un modelo computacional de expectativa musical, que es un aspecto muy importante de como procesamos la música que oímos. Muchos fenómenos relacionados con el procesamiento de la música están vinculados a una capacidad para anticipar la continuación de una pieza de música. Nos enfocaremos en un acercamiento estadístico de la expectativa musical, modelando los procesos de aprendizaje y de predicción de las regularidades espectro-temporales de forma causal. El principio de modelado estadístico de la expectativa se puede aplicar a varias representaciones de estructuras musicales, desde las notaciones simbólicas a la señales de audio. Primero demostramos que ciertos algoritmos de aprendizaje de secuencias se pueden usar y evaluar en el contexto de la percepción y el aprendizaje de secuencias auditivas. Luego, proponemos una representación, denominada qué/cuándo, para representar eventos musicales de una forma que permite describir y aprender la estructura secuencial de unidades acústicas en señales de audio musical. Aplicamos esta representación para describir y anticipar características tímbricas y ritmos. Sugerimos que se pueden explotar las propiedades del modelo de expectativa para resolver tareas de análisis como la segmentación estructural de piezas musicales. Finalmente, exploramos las implicaciones de nuestro modelo a la hora de definir nuevas aplicaciones en el contexto de la transcripción en tiempo real, la síntesis concatenativa y la visualización.

Η εξελικτική δυσλεξία είναι μια ειδική μαθησιακή δυσκολία στην κατάκτηση του γραπτού λόγου που δεν σχετίζεται με χαμηλό νοητικό δυναμικό, ελλιπείς εκπαιδευτικές ευκαιρίες ή κάποιο εμφανές αισθητηριακό ή νευρολογικό πρόβλημα. Σύμφωνα με την «υπόθεση των φωνολογικών αναπαραστάσεων», που έχει υποστηριχθεί από δεδομένα στην αγγλική γλώσσα, τα άτομα με δυσλεξία παρουσιάζουν δυσκολία στην επαρκή αποθήκευση και ανάσυρση ακολουθιών ήχων που απαρτίζουν λέξεις, δηλαδή στη διαμόρφωση επαρκών «φωνολογικών αναπαραστάσεων». Στην παρούσα εργασία εξετάστηκε συστηματικά η παραπάνω υπόθεση. Δύο ομάδες 25 (επιλεγμένων από την κοινή τάξη) και 20 (με επίσημη διάγνωση από το ΚΕΔΔΥ) δυσλεξικών μαθητών εξετάστηκαν παράλληλα με δύο ομάδες ελεγχου: η πρώτη ίδιας χρονολογικής ηλικίας και καλής αναγνωστικής ικανότητας και η δεύτερη μικρότερης χρονολογικής ηλικίας και ανάλογης αναγνωστικής ικανότητας με τους δυσλεξικούς. Διαπιστώθηκαν ήπιες δυσκολίες των δυσλεξικών αναφορικά με την ποιότητα των φωνολογικών τους αναπαραστάσεων, όπως αξιολογήθηκε από την ικανότητά τους στην κατονομασία εικόνων. Από την άλλη, οι συσχετίσεις της επίδοσής τους στην κατονομασία εικόνων με επιδόσεις σε δοκιμασίες επεξεργασίας εξερχόμενης και εισερχόμενης φωνολογικής πληροφορίας, αλλά και φωνολογικής επίγνωσης, βασισμένων μάλιστα στα ίδια στοιχεία του λεξικού με εκείνα που είχαν χρησιμοποιηθεί στη δοκιμασία κατονομασίας εικόνων, δεν ήταν σε όλες τις περιπτώσεις ιδιαίτερα ισχυρές. Πιθανοί αιτιολογικοί παράγοντες για τις δυσκολίες των δυσλεξικών μαθητών στο φωνολογικό επίπεδο διερευνήθηκαν τόσο σε γνωστικό όσο και σε αντιληπτικό επίπεδο. Σε γνωστικό επίπεδο, ο παράγοντας της «συχνότητας» της φωνολογικής αναπαράστασης φάνηκε να σχετίζεται ισχυρότερα με την ποιότητα των φωνολογικών αναπαραστάσεων όλων των μαθητών ανεξάρτητα από το επίπεδο αναγνωστικής ικανότητας, σε σχέση με τον παράγοντα του «αριθμού των συλλαβών». Τέλος, σε αντιληπτικό επίπεδο εξετάστηκαν δύο παράμετροι της ακουστικής αντίληψης ως πιθανοί αιτιολογικοί παράγοντες των δυσκολιών των δυσλεξικών στη φωνολογική επεξεργασία: α. η αντίληψη ταχύτατα παρουσιαζόμενων ακουστικών ερεθισμάτων (Tallal) και β. η αντίληψη του κέντρου του ακουστικού ερεθίσματος (p-center, Goswami). Τα αποτελέσματα δεν φαίνεται να υποστηρίζουν τις υποθέσεις για πιθανά ελλείμματα στις συγκεκριμένες παραμέτρους ακουστικής αντίληψης που εξετάστηκαν. / Developmental dyslexia is a specific learning difficulty in acquiring literacy skills that manifests despite normal IQ, adequate educational opportunity and in the absence of any obvious sensory or neurological damage. According to the “Phonological Representations Hypothesis”, a hypothesis that has been supported by research in English, a core deficit for individuals with dyslexia is a difficulty in accurately storing and retrieving the sound sequences that make up words, or “phonological representations”. In this thesis the “Phonological Representations Hypothesis” of dyslexia was tested and elaborated. Two groups of 25 (chosen from normal classes) and 20 (with formal diagnosis from the National Center of Diagnosis, Differential Diagnosis and Educational Support of Greece) dyslexics were assessed alongside chronological age and reading ability matched groups. Mild difficulties of dyslexics were found as far as the quality of the phonological representations is concerned, as indexed by picture naming. Assossiations between performance in picture naming and performance on related input and output phonological processing tasks and phonological awareness taks were not in all cases strong. Possible reasons for dyslxexic’s phonological difficulties were investigated at both cognitive and perceptual levels. As far as the cognitive level is concerned, “frequency” rather than “ length” of the phonological representation was found to be associated more strongly with the quality of the phonological representation of all students independently of their reading ability. As far as the perceptual level is concerned, two different explanatory factors for dyslexic’s difficulties in phonological processing were assessed: a. perception of rapidly presented auditory stimuli (Tallal, 1980) and b. perception of the perceptual center of acoustic signals (p-center, Goswami, 2002). Results are not stronlgy supportive of the two hypotheses tested concerning deficits in parameters of perception of acoustic stimuli.

Introdução: A otite média com efusão recorrente nos primeiros cinco anos de vida é considerada um indicador de risco para alterações no processamento auditivo central (PAC). No entanto, não foram encontrados estudos que avaliassem o PAC em sujeitos com otite média crônica. Em virtude da gravidade e cronicidade da doença, destaca-se a relevância deste estudo. Objetivo: Investigar e analisar o impacto da otite média crônica não colesteatomatosa (OMCNC) no processamento auditivo central e em alguns aspectos neuropsicológicos de adolescentes. Métodos: Trata-se de um estudo observacional, transversal controlado, no qual foram recrutados 34 adolescentes de 12 a 18 anos com diagnóstico de otite média crônica não colesteatomatosa oriundos de um ambulatório de atendimento a indivíduos com otite média crônica de um hospital do sul do país. Um grupo controle de 34 adolescentes pareados por idade, sexo, renda familiar e escolaridade materna foi estabelecido para o estudo. A avaliação dos indivíduos da amostra foi realizada por meio dos seguintes procedimentos: anamnese, audiometria tonal liminar, logoaudiometria, bateria de avaliação comportamental do processamento auditivo central (Masking Level Difference- MLD, Synthetic Sentence Identification com mensagem competitiva ipsilateral- SSI/MCI, Random Gap Detection Test- RGDT, Duration Pattern Sequence- DPS e Teste Dicótico de Dígitos- DD) e alguns subtestes do Instrumento de Avaliação Neuropsicológica Breve Neupsilin (tarefas de atenção, memória de trabalho e função executiva). Resultados: Em relação ao PAC, verificou-se diferença estatisticamente significativa entre as médias observadas entre os grupos estudo e controle em todos os testes realizados: MLD (p= 0,001), SSI em relação sinal/ruído de 0 dB (p< 0,001) em ambas as orelhas, SSI em relação sinal-ruído de -15dB (p< 0,001) em ambas as orelhas, RGDT (p< 0,001), DPS (p=0,002), DD na orelha direita (p= 0,001) e DD na orelha esquerda (p=0,003). Nos sub testes do Neupsilin, observou-se diferença significativa entre os grupos nas seguintes tarefas: repetição de sequência de dígitos (p= 0,011), ordem ascedente de dígitos (p= 0,025), span auditivo de sentenças (p= 0,002) e fluência verbal fonêmica (p= 0,001). Conclusões: Foi constatado impacto no PAC e nos subtestes de atenção, memória e função executiva em adolescentes com otite média crônica não colesteatomatosa. Desta forma, ressalta-se a necessidade de encaminhamento de sujeitos com a doença para avaliação e intervenção terapêutica. / Introduction: Otitis media with recurrent effusion in the first five years of life is considered an indicator of risk for alterations in central auditory processing (CAP). However, no studies were found evaluating CAP in subjects with chronic otitis media. Due to the severity and chronicity of the disease, the relevance of this study stands out. Objective: To investigate and analyze the impact of chronic non-cholesteatomatous otitis media on central auditory processing and on neuropsychological aspects in adolescents. Methods: This was a cross-sectional, observational study in which 34 adolescents aged 12 to 18 years with a diagnosis of chronic non-cholesteatomatous otitis media from an outpatient clinic for individuals with chronic otitis media were recruited from a hospital in southern Brazil. A control group of 34 adolescents matched by age, sex, family income and maternal schooling was established for study. The evaluation of the subjects was performed through the following procedures: anamnesis, tonal threshold audiometry, logoaudiometry, behavioral evaluation of central auditory processing battery (Masking Level Difference- MLD, Synthetic Sentence Identification with ipsilateral competitive message- SSI / MCI, Random Gap Detection Test- RGDT, Duration Pattern Sequence- DPS and Digit Dichotic Test- DD) and some subtests of the Neupsilin Brief Neuropsychological Assessment Instrument (attention, working memory and executive function). Results: In relation to CAP, a statistically significant difference was observed between the means observed between the study and control groups in all the tests performed: MLD (p = 0.001), SSI in 0 dB signal-to-noise ratio in both ears (p <0.001), SSI in -15dB signal-to-noise ratio in both ears (p = 0.001), RGDT (p < 0,001), DPS (p=0,002), DD in the right ear (p = 0.001) and DD in the left ear (p= 0.003). In the Neupsilin sub-tests, a significant difference was observed between groups in the following sub-tests: digit sequence repetition (p = 0.011), digit ascending order (p = 0.025), auditory sentence span (p = 0.002), and Phonemic verbal fluency (p = 0.001). Conclusions: Impact on PAC and on subtests of attention, memory and executive function were observed in adolescents with chronic non-cholesteatomatous otitis media. Thus, the need to refer subjects with the disease for evaluation and therapeutic intervention is emphasized.

However, the specific mechanisms have not been fully elucidated and the results are controversial. This study purposed to investigate the auditory perception in women during the menstrual cycle. In this research we developed two articles: the first is a systematic review entitled "auditory perception evaluation in women during the menstrual cycle: a systematic review", which purposed to pursue studies that show the relationship between hormones and auditory perception. The final sample of this systematic review consisted of seven articles. It was found that gonadal steroid hormones can interfere with the auditory perception of women, pointing to the dichotic tests as the one used for assessing auditory perception in this population. This article has been submitted for publication in the Journal of Otolaryngology. The second article was developed with empirical data from field research, which aimed to investigate the dichotic listening women during the menstrual cycle. The participants were 20 volunteers, 09 female and 11 male. They underwent a basic audiological evaluation, blood plasma collection (women only) and evaluation of dichotic listening through three behavioral tests: dichotic SSW, dichotic digits and consonant-vowel. There was improved performance of the right ear in the follicular phase of the menstrual cycle for the SSW test, with significant results. Moreover, when the ears were compared at each stage, there is better performance right ear in both phases and groups for the consonant-vowel pattern, showing significant results. This article will be submitted to codas journal. / As flutuações nos níveis dos hormônios esteroides gonadais durante o ciclo menstrual podem influenciar, dentre outras questões, o processamento da informação auditiva no cérebro. No entanto, os mecanismos específicos não foram totalmente elucidados e os resultados ainda são controversos. Este estudo teve como objetivo investigar a percepção auditiva em mulheres durante o ciclo menstrual. Neste trabalho foram desenvolvidos dois artigos: o primeiro é uma revisão sistemática, intitulada “Avaliação da percepção auditiva em mulheres durante o ciclo menstrual: revisão sistemática”, que teve o objetivo de buscar pesquisas que evidenciam a relação entre hormônios e percepção auditiva. Foram selecionados 7 artigos para revisão sistemática. Verificou-se que os hormônios esteroides gonadais podem influenciar a percepção auditiva das mulheres, apontando os testes dicóticos como o único utilizado para a avaliação da percepção auditiva nesta população. O segundo artigo foi desenvolvido com dados empíricos de uma pesquisa de campo, o qual teve por objetivo de investigar a escuta dicótica de mulheres durante o ciclo menstrual. Participaram da pesquisa 20 voluntários, sendo 09 do sexo feminino e 11 do sexo masculino. Os mesmos foram submetidos a uma avaliação audiológica básica, coleta de plasma sanguíneo (apenas as mulheres) e a avaliação da escuta dicótica através de três testes comportamentais: dicótico de dissílabos alternados (SSW), dicótico de dígitos (DD) e consoante-vogal (CV). Observou-se melhor desempenho da orelha direita na fase folicular do ciclo menstrual para o teste SSW, apresentando resultados significativos. Além disso, quando as orelhas foram comparadas entre si em cada fase, observou-se melhor desempenho da orelha direita em ambas as fases e grupos (homens e mulheres) para o teste consoante-vogal, apresentando resultados significativos.

The sample of this study was comprised of 30 adults (15 blinds (Experimental Group - EG) and 15 with normal vision (Control Group - CG)), 7 females and 8 males in each group from 18 to 30 years old, all with normal hearing acuity. All measurements were made by the forced-choice method between two alternatives. In this method, the volunteer had always to choose the certain stimulus informed previously by the experimenter (the test stimulus) between two stimuli. The other stimulus showed was a distracter stimulus. The measurements were made in 3 experimental sessions, one for each stimulus. In each experimental session, 20 pairs of stimuli were presented at random, one stimulus was the test stimulus and the other the distracter stimulus. The musical notes used as test stimulus were D, F and A in the first octave of the piano. The distracter stimulus were the musical notes that are neighboring the test note according to the standard musical notes scale (it means that when D was the test note, the distracter notes were C and E; to the F note, the distracters were E and G). Before the beginning of the experiment, the test stimulus of the session was presented for five consecutive times and the experiment only began when the experimenter was sure that the volunteer had understood all the instructions. The rate of discrimination (the number of rights divided per the number of presentations) for each musical note were gathered according to condition (CG and EG). The statistical analysis (One-Way ANOVA) did not show significant differences between the groups F (2, 27) = 2.17, p > 0.05 to discriminate musical notes. These results suggest that the congenital lack of vision do not cause changes in the ability to discriminate musical notes in blind adults. / A presente dissertação objetivou avaliar se a privação do sistema visual altera a percepção de notas musicais de adultos cegos quando comparados a adultos com visão normal. Participaram desse estudo 30 adultos (15 cegos (Grupo Experimental - GE) e 15 com visão normal (Grupo Controle - GC)), sendo 7 do sexo feminino e 8 do sexo masculino, em cada grupo, na faixa etária de 18 a 30 anos de idade, todos com acuidade auditiva normal. Todas as medidas foram realizadas com o método da escolha forçada entre duas alternativas. Neste método, o voluntário teve sempre de escolher entre dois estímulos o estímulo pré-determinado pelo pesquisador de estímulo teste . O outro estímulo apresentado era um estímulo distrator . Foram realizadas três sessões experimentais, uma para cada estímulo teste. Em cada sessão experimental foram apresentados aleatoriamente 20 pares de estímulos, sendo um deles o estímulo teste e o outro o estímulo distrator. As notas musicais utilizadas como teste foram Ré, Fá, Lá na primeira oitava do piano. Os estímulos distratores foram as notas que na escala padrão de notas musicais encontram-se vizinhas a nota de teste (ou seja, quando a nota de teste foi Ré, as notas distratoras foram Dó e Mi; para a nota Fá, as distratoras foram Mi e Sol; e para a nota teste Lá, as distratoras foram Sol e Si). Antes do início do experimento a nota teste, referente aquela sessão, foi apresentada cinco vezes consecutivas e o experimento só foi iniciado quando foi certificado que as instruções foram compreendidas pelo participante. Os índices de discriminação (número de acertos divididos pelo número de apresentações) para cada nota musical foram reunidas por condição (GC e GE). A análise estatística (ANOVA One-Way) não mostrou diferença significativa entre os grupos F (2, 27) = 2,17, p > 0,05 quanto a discriminação de notas musicais. Estes resultados sugerem que a privação visual congênita não causa alterações na habilidade de discriminação de notas musicais em adultos cegos.
