Inadequate and infrequent are not alike : ERPs to deviant prosodic patterns in spoken sentence comprehension

The current study on German investigates Event-Related brain Potentials (ERPs) for the perception of sentences with intonations which are infrequent (i.e. vocatives) or inadequate in daily conversation. These ERPs are compared to the processing correlates for sentences in which the syntax-to-prosody relations are congruent and used frequently during communication. Results show that perceiving an adequate but infrequent prosodic structure does not result in the same brain responses as encountering an inadequate prosodic pattern. While an early negative-going ERP followed by an N400 were observed for both the infrequent and the inadequate syntax-to-prosody association, only the inadequate intonation also elicits a P600.

Prosodic differences between Germans and German-speaking Swiss in L2

Cette recherche étudie dans quelle mesure l'origine géographique d'un locuteur influence son accent dans une langue étrangère. L'anglais et le français parlés par des Allemands et des Suisses alémaniques sont examinés à travers une expérience de perception et d'analyses phonétiques. L'expérience de perception démontre que les participants sont bien capables d'indiquer si une phrase est lue par un Allemand ou un Suisse alémanique; les participants de langue maternelle allemande y réussissent le mieux. L'analyse prosodique permet d'observer de nettes différences entre les deux groupes de locuteurs. Dans la lecture des phrases françaises, les Suisses alémaniques ont tendance à accentuer la première syllabe des mots, en montant avec leur intonation et en prolongeant la durée des voyelles. Les Allemands, en revanche, accentuent par une intonation fortement montante la dernière syllabe des mots.

"Echoing approval": a new speech disorder.

We report the cases of two patients presenting a peculiar speech disorder, which we have named "echoing approval", in which the patients echo, in replying to questions in a dialogue with short phrases, the positive or negative syntactical construction of a question, or its positive or negative intonation, but without any repetition of whole or part of sentences. When asked about their symptoms, the patients replied 80% of the time with "yes, yes", "that's right", or "exactly" to positive questions and "no, no" or "absolutely not" to negative questions, regardless of their actual symptoms and oblivious to self-contradiction. In addition, when the examining doctor was speaking to a medical colleague in the patient's presence and using medical terminology that the patient did not understand, he/she agreed or disagreed with any sentence and technical word uttered in a way entirely dependent on the syntax or intonation used. To distinguish this speech disorder from echolalia or verbal perseverations, with which it may be superficially confused, we suggest that it be called "echoing approval", as it may be part one of the manifestations of the environment-dependency syndrome. This clinical picture was found to be associated with features of transcortical motor aphasia and frontal lobe signs. One patient had a bilateral callosofrontal malignant glioma and the other a probable multiple system atrophy with global deterioration, pre-eminent frontal release signs, diffuse leukoencephalopathy and multiple lacunes. On the basis of these clinical deficits and neuroimaging features, we are unable to delineate the common, or minimal, lesioned network required for this symptomatology to occur, especially in the absence of a series of patients, and with such a difference in both the location and causes of the lesions. However, bilateral frontosubcortical dysfunction was pre-eminent in the clinical picture in both patients, even though more diffuse brain pathology was seen in one, and it might be speculated that dysfunction of the bilateral orbitofrontal and frontomesial motor frontosubcortical circuits might be involved in the aetiology of this peculiar speech disorder.

"Il corpo de'pensieri" : la versificazione dei "Canti" leopardiani

L'objet de la thèse est l'étude de l'endecasillabo dans l'oeuvre poétique de Giacomo Leopardi. D'un point de vue méthodologique, ce travail s'appuie sur la recherche de Marco Praloran et Arnaldo Soldani dédiée à l'endecasillabo de Pétrarque. L'auteur a comparé les Canti de Leopardi avec la production des plus grands écrivains de la fin du XIXème siècle et du début du XXème siècle Melchiorre Cesarotti (Poesie di Ossian), Giuseppe Parini (Il Mattino), Vittorio Alfieri (Le Rime e il Saul), Vincenzo Monti (l'ouvre poétique), Ugo Foscolo (Le Rime) et Alessandro Manzoni (l'oeuvre poétique). Nous avons là un répertoire de plusieurs milliers de vers qui ont été scandés non pas par l'intermédiaire d'un ordinateur, mais un à un en fonction de leur intonation. La première partie de la thèse est dédiée à l'analyse du rythme des différents auteurs, à des statistiques générales qui permettent de comparer ces données entre elles et avec les anciens auteurs italiens tels Dante, Pétrarque, Arioste, etc. De cette façon, nous pouvons avoir une vision globale de la prosodie italienne des origines jusqu'au XIXème siècle -vision qui permet de focaliser de manière exhaustive la technique de Leopardi. Dans la deuxième partie, l'auteur propose texte après texte la scansion de toute l'oeuvre poétique de Leopardi. Nous avons donc une lecture interprétative du rythíne de tous les poèmes qui tient compte de l'année de composition et les différentes typologies métriques des textes : par exemple, les canzoni, les idilli, les canti pisano-recanatesi. Dans cette deuxième partie, il faut souligner l'effort de lier la partition du rythme au contenu des différents textes.

Speech prognosis and need of pharyngeal flap for non syndromic vs syndromic Pierre Robin Sequence

BACKGROUND: The aim of this retrospective study was to evaluate speech outcome and need of a pharyngeal flap in children born with nonsyndromic Pierre Robin Sequence (nsPRS) vs syndromic Pierre Robin Sequence (sPRS). METHODS: Pierre Robin Sequence was diagnosed when the triad microretrognathia, glossoptosis, and cleft palate were present. Children were classified at birth in 3 categories depending on respiratory and feeding problems. The Borel-Maisonny classification was used to score the velopharyngeal insufficiency. RESULTS: The study was based on 38 children followed from 1985 to 2006. For the 25 nsPRS, 9 (36%) pharyngeal flaps were performed with improvements of the phonatory score in the 3 categories. For the 13 sPRS, 3 (23%) pharyngeal flaps were performed with an improvement of the phonatory scores in the 3 children. There was no statistical difference between the nsPRS and sPRS groups (P = .3) even if we compared the children in the 3 categories (P = .2). CONCLUSIONS: Children born with nsPRS did not have a better prognosis of speech outcome than children born with sPRS. Respiratory and feeding problems at birth did not seem to be correlated with speech outcome. This is important when informing parents on the prognosis of long-term therapy
