Children with pronunciation difficulties are at risk of consequences later on, such as reading and writing difficulties. Problems with pronunciation could make a child less intelligible and affect their ability to discriminate between different speech sounds. To facilitate the assessment of pronunciation difficulties it is necessary to use appropriate and updated assessment tools suitable to analyze the children’s phonological development. The Swedish pronunciation test, Bedömning Av Fonologi (B.A.F.), has therefore been developed. This new test can be used by professionals to evaluate the phonological realisations of children. The purpose of this study was to gather normative data of 4 and 5 year olds for B.A.F. and to investigate if girls and boys performed differently concerning the pronunciation of the words in B.A.F. Furthermore, the intention was to investigate if there was any correlation in the performance of the words in B.A.F. with oral motor precision (by oral motor movements tasks), oral motor speed (by repeating syllables) as well as auditory perception (by repetition of nonwords). 63 children (36 girls and 27 boys) in the ages of 48 to 71 months participated in the study. The results showed that by using B.A.F. it is possible to see that the number of correctly pronounced words increases with age. Further, the results indicated that children in the ages of four and five had established /p, t, k, d, f, v, j, h, l, m, n/ and /ŋ/ and all the vocals except /y:/ and /Y/. The only speech sound that did not prove to be established was /r/. Neither the 4 nor the 5 year olds had established consonant clusters containing /r/. A significant correlation was found between oral motor speed and correctly pronounced words in B.A.F. The children’s auditory perception also correlated with the number of correctly pronounced words in B.A.F. This study suggests that skills concerning auditory perception and oral motor speed have more effect on pronunciation skills than oral motor precision. The results gave no indication of a difference in pronunciation between girls and boys. / Barn med uttalssvårigheter löper risk för senare konsekvenser, som exempelvis läs- och skrivsvårigheter. Problem med uttal kan göra ett barn svårförståeligt för omgivningen och kan påverka förmågan att särskilja mellan språkljud. För att underlätta bedömningen av uttalssvårigheter behövs uttalstest som är aktuella och anpassade efter barns utveckling. Därför har det nya uttalstestet Bedömning Av Fonologi (B.A.F.) producerats. Med hjälp av B.A.F. kan barns fonologi undersökas genom uttal av språkljud i ord. Denna studie syftade till att ta fram normativa data för testet hos 4- och 5-åringar. Studien syftade även till att undersöka om några skillnader mellan könen gällande prestationen på B.A.F. fanns samt om något samband mellan uttal av orden i B.A.F. och ett antal uppgifter som mätte oralmotorisk precision (oralmotoriska rörelser) och snabbhet (upprepning av stavelser), samt auditiv perception (repetition av nonord) kunde påvisas. I studien deltog 63 barn (36 flickor och 27 pojkar) i åldrarna 4;0 år till 5;11 år. Under analysen delades barnen in i grupper av halvårsintervall. Resultaten visade att man i B.A.F. kan se att antal korrekt uttalade ord ökar i linje med stigande ålder. Det påvisades även att barn i fyra- och fem årsåldern etablerat /p, t, k, d, f, v, j, h, l, m, n/ och /ŋ/ samt alla vokaler utom /y:/ och /Y/. Det enda konsonantfonem som ej visade sig vara etablerat i dessa åldrar var /r/. Ingen av åldersgrupperna hade heller etablerat kluster innehållandes /r/. Ett signifikant samband kunde påvisas mellan oralmotorisk snabbhet och antal korrekt uttalade ord i B.A.F. Även barnens auditiva perception korrelerade signifikant med antal korrekt uttalade ord i B.A.F. Föreliggande studie tyder på att auditiv perception och oralmotorisk snabbhet har ett större samband med uttalet än oralmotorisk precision. Inga uttalsskillnader mellan könen framkom.

L’objectif de ce travail de thèse était d’investiguer l’influence de la valence émotionnelle négative, positive ou taboue des mots parlés sur l’orientation des ressources attentionnelles, dans la population tout-venant. Pour ce faire, j’ai élaboré des adaptations auditives de paradigmes expérimentaux qui avaient été utilisés auparavant dans le but d’explorer l’influence du contenu émotionnel de stimuli visuels sur l’allocation de l’attention :le paradigme de déploiement de l’attention (Etudes 1 et 3), le paradigme de Stroop émotionnel (Etude 2) et le paradigme d’indiçage spatial émotionnel (Etude 4). <p>En particulier, les Etudes 1, 3 et 4 m’ont permis d’examiner l’influence de la valence émotionnelle de ces stimuli sur l’attention sélective à une localisation spatiale, évaluée au travers des réponses à une cible subséquente. <p>Dans la situation de compétition pour les ressources attentionnelles spécifique au paradigme de déploiement de l’attention (Etudes 1 et 3), nous avons observé un engagement préférentiel des ressources attentionnelles vers la localisation spatiale des mots tabous, lorsque ceux-ci étaient présentés à droite, par rapport à la localisation spatiale des mots neutres présentés conjointement. Ces biais attentionnels ont été observés quelle que soit l’attention portée volontairement aux stimuli, la nature de la tâche à réaliser sur la cible, ou la charge cognitive liée à la tâche. De tels biais ont également été observés envers la localisation spatiale des mots négatifs et positifs, mais de manière moins robuste. Lorsque deux stimuli rivalisent pour l’orientation des ressources, la valence choquante serait donc cruciale pour l’orientation de l’attention spatiale. De plus, les mots tabous induisent un ralentissement général des temps de réaction (TRs) à la cible subséquente, quelle que soit sa localisation spatiale.<p>Au contraire, lorsque des mots-indices sont présentés isolément dans le paradigme d’indiçage spatial émotionnel (Etude 4), la valence émotionnelle négative des mots, mais pas leur valence choquante, paraît cruciale pour l’observation d’effets spatiaux :les stimuli les plus négatifs moduleraient l’orientation spatiale automatique de l’attention suscitée par leur présentation périphérique. Plus précisément, ils empêcheraient l’application de processus attentionnels inhibiteurs des localisations déjà explorées. En outre, la présentation d’un indice périphérique négatif accélère le traitement d’une cible subséquente, quelle que soit sa localisation spatiale.<p>L’influence de la dimension émotionnelle des mots parlés sur l’attention sélective à une dimension (non-émotionnelle) de ces stimuli a été investiguée grâce au paradigme de Stroop émotionnel (Etude 2). Contrairement à mes autres études, aucun déplacement attentionnel spatial n’était impliqué dans cette situation puisque les participants devaient répondre à chaque essai à une dimension non-émotionnelle (l’identité du locuteur) du stimulus (potentiellement émotionnel) présenté. J’ai ainsi observé une influence de la dimension émotionnelle taboue ou négative des mots sur le traitement de la dimension pertinente d’un mot neutre subséquent, mais pas sur le traitement de la dimension pertinente de ces mots eux-mêmes, suggérant l’occurrence d’effets lents, inter-essais, des mots tabous et négatifs, mais pas d’effet rapide. <p>Ces données appuient donc l’existence, dans une population tout-venant, d’un mécanisme de traitement involontaire du contenu émotionnel des mots parlés qui influence non seulement l’orientation spatiale et dimensionnelle de l’attention mais également, de manière plus générale, la latence des réponses fournies par le sujet.<p> / Doctorat en Sciences Psychologiques et de l'éducation / info:eu-repo/semantics/nonPublished

L’objectif de ce travail était d’examiner la spécificité fonctionnelle du traitement et des représentations des hauteurs musicales. À cette fin, ce traitement a été comparé à celui des phonèmes de la parole, d’une part, et aux associations spatiales évoquées par des séquences ordonnées, d’autre part. Nos quatre études avaient pour point commun d’adapter à un nouvel objet de recherche des méthodes bien établies en psychologie cognitive. Ainsi, nous avons exploité la tâche de classification accélérée (Etude 1) de Garner (1974), l’analyse des conjonctions illusoires en mémoire (Etude 2), l’additivité de la composante mismatch negativity (MMN) des potentiels évoqués (Etude 3) et l’observation d’associations spatiales de codes de réponse (Etude 4).<p>Les trois premières études, menées chez des participants non-musiciens, portaient sur la spécificité de traitement des hauteurs par rapport à celui des phonèmes au sein de stimuli chantés. Les deux premières études ont mis en évidence un effet surprenant de la nature des phonèmes sur leurs interactions avec le traitement des mélodies :les voyelles apparaissaient plus intégrées à la mélodie que les consonnes. Ceci était vrai à la fois lors du traitement en temps réel de non-mots chantés (Etude 1) et au niveau des traces en mémoire de ces mêmes non-mots (Etude 2, utilisant une tâche de reconnaissance à choix forcé permettant la mise en évidence de conjonctions illusoires). Cette dissociation entre voyelles et consonnes quant à leur intégration avec les traitements mélodiques ne semblait pas causée par des caractéristiques acoustico-phonétiques telles que la sonorité. Les résultats de la troisième étude indiquaient que les MMNs en réponse à des déviations de hauteur et de voyelle n’étaient pas additives et que leur distribution topographique ne différait pas selon le type de déviation. Ceci suggère que, même au niveau pré-attentionnel, le traitement des voyelles n’est pas indépendant de celui des hauteurs. <p>Dans la quatrième étude, nous avons comparé le traitement des hauteurs musicales à un autre domaine :la cognition spatiale. Nous avons ainsi montré que les non-musiciens comme les musiciens associent les notes graves à la partie inférieure et les notes aiguës à la partie supérieure de l’espace. Les deux groupes liaient aussi les notes graves au côté gauche et les notes aiguës au côté droit, mais ce lien n’était automatique que chez les musiciens. Enfin, des stimuli musicaux plus complexes (intervalles mélodiques) n’évoquaient ces associations spatiales que chez les musiciens et ce, uniquement sur le plan horizontal.<p>Ces recherches contribuent de plusieurs manières à la compréhension de la cognition musicale. Premièrement, nous avons montré que les consonnes et les voyelles diffèrent dans leurs interactions avec la musique, une idée à mettre en perspective avec les rôles différents de ces phonèmes dans l’évolution du langage. Ensuite, les travaux sur les représentations spatiales des hauteurs musicales ouvrent la voie à un courant de recherche qui aidera à dévoiler les liens potentiels entre habiletés musicales et spatiales.<p>/<p>The purpose of this work was to examine the functional specificity of musical pitch processing and representation. To this aim, we compared musical pitch processing to (1) the phonological processing of speech and (2) the spatial associations evoked by ordered sequences. The four studies described here all use classical methods of cognitive psychology, which have been adapted to our research question. We have employed Garner’s (1974) speeded classification task (Study 1), the analysis of illusory conjunctions in memory (Study 2), the additivity of the mismatch negativity (MMN) component of event-related potentials (Study 3), as well as the observation of spatial associations of response codes (Study 4).<p>The three first studies examined, in non-musician participants, the specificity of pitch processing compared to phoneme processing in songs. Studies 1 and 2 revealed a surprising effect of phoneme category on their interactions with melodic processing: vowels were more integrated with melody than were consonants. This was true for both on-line processing of sung nonwords (Study 1) and for the memory traces of these nonwords (Study 2, using a forced-choice recognition task allowing the occurrence of illusory conjunctions). The difference between vowels and consonants was not due to acoustic-phonetic properties such as phoneme sonority. The results of the third study showed that the MMN in response to pitch and to vowel deviations was not additive and that its brain topography did not differ as a function of the kind of deviation. This suggests that vowel processing is not independent from pitch processing, even at the pre-attentive level.<p>In the fourth study, we compared pitch processing to another domain: spatial cognition. We showed that both musicians and non-musicians map pitch onto space, in that they associate low-pitched tones to the lower spatial field and high-pitched tones to the higher spatial field. Both groups of participants also associated low pitched-tones with the left and high-pitched tones with the right, but this association was automatic only in musicians. Finally, more complex musical stimuli such as melodic intervals evoked these spatial associations in the horizontal plane only in musicians.<p>This work contributes to the understanding of music cognition in several ways. First, we have shown that consonants and vowels differ in their interactions with music, an idea related to the contrasting roles of these phonemes in language evolution. Second, the work on the spatial representation of pitch opens the path to research that will help uncover the potential links between musical and spatial abilities.<p> / Doctorat en sciences psychologiques / info:eu-repo/semantics/nonPublished

Predictive coding theorizes the capacity of neural structures to form predictions about forthcoming sensory events based on previous sensory input. This concept increasingly gains attention within experimental psychology and cognitive neuroscience. In auditory research, predictive coding has become a useful model that elegantly explains different aspects of auditory sensory processing and auditory perception. Many of these aspects are backed up by experimental evidence. However, certain fundamental features of predictive auditory processing have not been addressed so far by experimental investigations, like correlates of neural predictions that show up before the onset of an expected event. Four experiments were designed to investigate the proposed mechanism under more realistic conditions as compared to previous studies by manipulating different aspects of predictive (un)certainty, thereby examining the ecological validity of predictive processing in audition. Moreover, predictive certainty was manipulated gradually across five conditions from unpredictable to fully predictable in linearly increasing steps which drastically decreases the risk of discovering incidental findings. The results obtained from the conducted experiments partly confirm the results from previous studies by demonstrating effects of predictive certainty on ERPs in response to omissions of potentially predictable stimuli. Furthermore, results partly suggest that the auditory system actively engages in stimulus predictions in a literal sense as evidenced by gradual modulations of pre-stimulus ERPs associated with different degrees of predictive certainty. However, the current results remain inconsistent because the observed effects were relatively small and could not consistently be replicated in all follow-up experiments. The observed effects could be regained after accumulating the data across all experiments in order to increase statistical power. However, certain questions remain unanswered regarding a valid interpretation of the results in terms of predictive coding. Based on the current state of results, recommendations for future investigations are provided at the end of the current thesis in order to improve certain methodological aspects of investigating predictive coding in audition, including considerations on the design of experiments, possible suitable measures to investigate predictive coding in audition, recommendations for data acquisition and data analysis as well as recommendations for publication of results.

OBJECTIVE: To determine in an interrupted word paradigm (Maryland CNCs; 10 ips, 50% duty cycle) if different locations of the interruption pattern produce different recognition performances. DESIGN: Repeated measures using two interruption patterns that were complementary halves referenced to word onset; one started with word onset (0-ms), the other started 50 ms later. The hypothesis was that recognition performance would be better on the 0-ms condition than on the 50-ms condition, but there would be some words with the reverse relation. STUDY SAMPLE: Twenty-four young adults with normal hearing for pure tones and 32 older adults (mean = 67 years) with sensorineural hearing loss participated. RESULTS: With the young listeners mean recognition performance on the 0-ms condition (63.1%) was significantly better than the mean performance on the 50-ms condition (47.8%). About twice as many words had better performance on the 0-ms condition. With the older listeners, who were given only stimuli on which performances were > 58% by the young normals, performances on the two conditions were the same. CONCLUSIONS: The hypothesis was supported with the young listeners. The equal performance by the older listeners on the two conditions was attributed to the manner in which the words were selected.

The aim of this action research was to investigate how auditory perceptual deficits affect reading in learners with disabilities. The sub-questions were: What auditory perceptual deficits learners’ experience? How do educators assist learners with auditory perceptual deficits? What instructional strategies and classroom management can educators apply to assist learners with auditory perceptual skills? The data collections comprised of an informal oral assessment, observation and anecdotal notes with fifteen participants with barriers to learning, from the English first year class, within a special needs educational setting. Data analysis and validity were supported by triangulation through informal assessment, observation, my critical friend and my own critical reflection. The support of phonologic, memory, and cohesion skills, auditory skills were the reading educational construct and strategies used as intervention in order to identify the efficacy of said interventions. Both bottom-up and top-down support strategies were used in relation to the participants’ individualised educational needs. The research results and discussion included methods to improve reading and listening skills in the classroom environment. / Inclusive Education / M. Ed. (Inclusive Education)

The second chapter summarizes the principles and specifics of teaching and further highlights the importance of touch and compensatory aids during the class. The third chapter follows the influence of reading and the spoken word for children with visual impairments. The fourth chapter deals with the current concept of teaching the Czech language. The fifth chapter is dedicated to competitions and cultural events, in which children at Elementary school of Jaroslav Jezek participate. Powered by TCPDF (www.tcpdf.org)

Le système auditif possède deux particularités. En périphérie, les mécanismes cochléaires actifs (MCA), sous-tendus par la motilité des cellules ciliées externes (CCE), interviennent dans la sensibilité auditive et la sélectivité fréquentielle. Sur le versant central, le système efférent olivocochléaire médian (SEOCM), qui se projette sur les CCE et module les MCA, améliore la perception auditive en milieu bruité. Sur le plan exploratoire, ces deux processus peuvent être évalués grâce aux otoémissions acoustiques provoquées (OEAP) et leur suppression controlatérale. Par ailleurs, des résultats expérimentaux chez l’animal ont montré l’existence d’un rétrocontrôle exercé par le système auditif corticofuge descendant (SACD) sur la cochlée, via le SEOCM.Le présent travail comporte trois études réalisées chez l’humain, visant à explorer les interactions entre SACD, SEOCM et MCA. Les études 1 et 2, utilisant une méthodologie innovante chez des patients épileptiques réalisant une stéréo-électroencéphalographie, ont révélé un effet atténuateur différentiel de la stimulation électrique intracérébrale sur l’amplitude des OEAP, en fonction des modalités de stimulation, ainsi qu’une variabilité de cet effet selon les caractéristiques de l’épilepsie. L’étude 3 a montré un renforcement bilatéral de l’activité du SEOCM chez des musiciens professionnels.Pris dans leur ensemble, ces résultats fournissent d’une part, des arguments directs et indirects en faveur de l’existence d’un SACD fonctionnel chez l’humain. D’autre part, des phénomènes de plasticité à long terme, pathologique ou supranormale, seraient susceptibles de modifier l’activité de cette voie cortico-olivocochléaire. / The auditory system has two special features. At peripheral level, active cochlear micromechanisms (ACM), underlain by motility of outer hair cells (OHC), are involved in auditory sensitivity and frequency selectivity. At central level, the medial olivocochlear efferent system (MOCES), which directly projects onto OHC to modulate ACM, improves auditory perception in noise. From an exploratory point of view, both processes can be assessed through transient evoked otoacoustic emissions (TEOAE) and the procedure of contralateral suppression. In addition, experimental data in animals have disclosed a top-down control exerted by corticofugal descending auditory system (CDAS) on cochlea, via MOCES.The present work comprises three studies carried out in human, aiming to investigate interactions between CDAS, MOCES and ACM. The first and second studies, based on an innovative experimental procedure in epileptic patients undergoing presurgical stereoelectroencephalography, have revealed a differential attenuation effect of intracerebral electrical stimulation on TEOAE amplitude depending on stimulation modalities, as well as a variability of this effect depending on the clinical history of epilepsy. The third study has shown a bilateral enhancement of MOCES activity in professional musicians.Taking together, these results provide direct and indirect evidence for the existence of a functional CDAS in humans. Moreover, possible long-term plasticity phenomenon, either pathological –as in epileptic patients– or supernormal –as in professional musicians– may change cortico-olivocochlear activity.

Die Geräte, durch die Musik im Zeitalter der technischen (Re-)Produktion gehört wird, haben sich immer wieder gewandelt. Solche Geräte müssen überhört werden. Nur so kann Musik gehört werden. Trotzdem – so die These der Arbeit – organisieren diese Geräte das Hören und sind Agenturen einer Bewirtschaftung und Technisierung der Wahrnehmung. In der Arbeit wird anhand von zwei Fallstudien aus der Geschichte der Rock- und Popmusik gezeigt, wie solche Geräte sowohl den Hörer als auch die gehörte Musik formieren. Durch Hörtechnologien bilden sich neue Hörpraktiken heraus und die Körperlichkeit des Hörers wird neu bestimmt. Die Anpassung von Klanggeschehen an spezifische Hörtechnologien wird im Mastering – dem letzten Schritt der technischen Musikproduktion – untersuchbar. Die Geräte, durch die Musik gehört wird, sind also weder schlichte Wiedergabetechnologien noch bloße elektrotechnische Artefakte. Vielmehr sind sie Gefüge aus Klanglichkeit, Körperlichkeit und Technologie. Diese werden in der Arbeit als Hörgeräte auf den Begriff gebracht. Die Hörgeräte der Rock- und Popmusik zielen – wie ihre medizintechnischen Verwandten – auf die Materialität der Wahrnehmung. Im Gegensatz zu diesen funktionieren sie jedoch nicht als Prothesen, die an einer gattungsweit postulierten Norm ausgerichtet sind. Statt Normen bergen sie Exzesse – an Serialität und Wiederholung – sowie Eskalationen – von Lautstärke und von hohen und tiefen Frequenzen. Die Arbeit ist in drei Kapiteln gegliedert. Im ersten Kapitel wird die These der Arbeit in Bezug auf theoretische Diskurse der Musik-, Kultur- und Medienwissenschaft verortet und eine begriffliche Systematik entwickelt. Kapitel zwei und drei sind Fallstudien gewidmet. In der ersten wird das Jukeboxhören der Rock’n’Roll-Kultur der 1950er Jahre untersucht, in der zweiten das Soundsystemhören der Disco- und Clubkultur der 1970er bis 1990er Jahre. Die im ersten Kapitel entwickelte begriffliche Systematik macht die Fallstudien vergleichbar. / The devices by which music is listened to in the age of technological (re-)production have changed over and over again. These devices must be imperceptible to the ear. Only then can music be heard. Nonetheless – this is the claim of the thesis – these devices organize hearing and are agents of a cultivation and technization of perception. Based on two case studies from the history of rock and pop music, this thesis reveals how such devices constitute not only the listener but also the music which is listened to. Through listening technologies new listening practices emerge and the corporality of the listener is newly defined. The adaptation of sound to specific listening technologies can be analysed during the mastering process, the last step in technological music production. The devices by which music is listened to are thus neither simple technologies of reproduction nor mere electrotechnical artefacts. Rather, they are assemblages of sound, corporality, and technology. In this thesis these assemblages are called “Hörgeräte” (listening devices). The listening devices of rock and pop music target – like medical-technical “Hörgeräte” (hearing aids) – the materiality of perception. Contrary to medical technologies, however, listening devices do not function as prostheses, which are calibrated according to medical industry standards. Instead, they contain excesses – of seriality and repetition – and escalations – of amplitude and high and low frequencies. The thesis is arranged in three chapters. In the first chapter I situate the main argument of the thesis within discourses of musicology, media and cultural studies, and develop my own terminology. Chapters two and three deal with case studies. In chapter two I investigate jukebox listening in 1950s rock’n’roll culture, whilst in chapter three I explore sound system listening in disco and club culture from the 1970s to the 1990s. The terminology developed in chapter one enables a comparison of the case studies.
