Laughing Together – the influence of laughter on interpersonal neural synchrony, bonding and prosociality

10h30-12h LPL

Abstract:
In this talk, I will present preliminary results on the effect of laughter on neural synchrony, bonding and prosocial intentions towards an interaction partner. Laughter is a rhythmic, audiovisual expression of emotion, often occurring during social interactions, and has been shown to increase bonding in a social group  through endorphine release. Being a multimodal, rhythmic social stimulus, laughter could be hypothesized to facilitate interpersonal synchrony. This, in turn, could contribute to increased affiliation and prosociality between interaction partners. The present study aimed at testing these hypotheses using functional near-infrared spectroscopy (fNIRS) hyperscanning. Results from a pilot dataset show that laughter increases neural synchrony in the inferior frontal gyrus, but such effect is not long lasting. In this talk, I will discuss implications and challenges for future research on laughter and synchrony.

Bio:
Carolina Pletti is Marie Skłodowska-Curie Fellow at the Institute for Developmental Psychology of the University of Vienna. Her research focusses on the development and neural mechanisms of social cognition, in particular moral cognition, prosociality, laughter, and interpersonal synchrony.

Défis et enjeux de l’analyse syntaxique en dépendances du créole mauricien

Résumé :
Depuis l’amorce de sa description linguistique au XIXe siècle (Baissac, 1880) jusqu’à l’officialisation étatique de son orthographe (Carpooran, 2011), la publication de sa première grammaire (Police-Michel et al., 2011) et son intronisation dans le système éducatif, le créole mauricien a progressivement évolué du statut de « patois » vers celui de « langue ». Les recherches scientifiques, notamment sur le plan linguistique, sociolinguistique et didactique, associées à cette langue créole à base française ainsi que son utilisation croissante dans l’écrit journalistique et littéraire ont davantage contribué à cet essor. Or, dans le domaine du traitement automatique des langues (TAL), et en l’absence de ressources informatiques qui lui sont propres, le créole mauricien possède le statut de langue peu dotée. La modélisation informatique de ses ressources linguistiques s’est donc avérée nécessaire, avec le développement d’une chaîne de traitement de premiers niveaux ayant permis son analyse automatique (David, 2019). Dans la continuation de ce traitement automatique, ce travail de recherche doctorale a pour but de construire un corpus arboré pour le créole mauricien afin de s’atteler à une tâche spécifique du TAL : l’analyse syntaxique en dépendances.

La politique du langage : exemples de recherches et perspectives en sociolinguistique et analyse du discours

Résumé :
Dans cette intervention, je présenterai mes recherches qui portent sur les usages des langues et de la parole dans le domaine du politique, principalement sur la gestion collective de la diversité linguistique et l’usage de la parole dans les relations d’emprise. Je parlerai de mes deux principales enquêtes. La première porte sur les politiques linguistiques en domaine occitan et plus spécifiquement sur le mouvement Calandretas qu vise depuis 40 ans à la revitalisation de la langue occitane par le biais de l’enseignement immersif. Cette étude permet de mieux comprendre les enjeux et les limites d’une action de revitalisation linguistique “par en bas”. La seconde enquête concerne l’analyse de discours issus de groupes “sectaires”. J’évoquerai ce que recouvre cette notion et les enjeux de l’étude de la parole dans un tel contexte.

Lancement du projet ARENAS : une approche critique et ethnographique des « récits extrémistes »

10h30-12h LPL

Résumé :
Le projet Horizon Europe Analysis of and Responses to Extremist Narratives (ARENAS) débutera en mai 2023 (https://cordis.europa.eu/project/id/101094731). Initié et rédigé par le groupe Discours de haine (Draine, https://groupedraine.github.io/), il a pour objectif d’identifier et de cartographier les « récits extrémistes » en Europe, d’en comprendre la diffusion et les effets, et de trouver des solutions de remédiation. Dans cette intervention, je commencerai par présenter le projet ARENAS, puis j’en discuterai les termes en exposant les problèmes méthodologiques et épistémologiques majeurs qu’ils posent. Enfin, je présenterai la tâche que je dirige, destinée à répondre en partie à ces problèmes. Il s’agira d’un travail ethnographique d’au moins un an, au sein des milieux politiques d’extrême-droite, qui entend comprendre précisément quels récits circulent et comment ils sont mis en mots.

Environmental impacts of Information Technology and AI

10h30-12h LPL, salle de conférences B011

The environmental impacts of information technology have been exposed for about 15 years. They have been recently updated through the shift project report [1] and a recent meta-analysis discussing trends and controversies [2], in particular regarding rebound effects. I will present more particularly quantitative tools in the field of AI (machine/deep learning) and a serious lack of evaluations for so-called AI solutions for environment [3], reflecting a general techno-solutionist state of mind. Those observations imply several conclusions, from a more critic approach in how to raise awareness for environmental issues and associated solutions [4] to a more global redirection of scientific activities taking into account planetary boundaries [5].

Imaging and stimulating the brain in people who stutter

Résumé :
Developmental stuttering affects about 5% of children and 1% of adults.  Fluency can be enhanced in people who stutter by altering sensory feedback during speech production and by altering production e.g. by whispering, changing pitch or accent, or by external cueing, speaking in unison or singing.  Abnormal sensorimotor integration and impairment in cortico-striatal-thalamo-cortical circuits might explain the occurrence and persistence of speech disfluency.  Brain imaging studies show some support for these theories.  I will present our early structural and functional brain imaging studies that revealed abnormal white matter microstructure underlying cortical differences in brain activity during speech.  In recent work, we found increased amounts of iron in the striatum in a large sample of people who stutter.  We have also used brain stimulation to enhance speech fluency in people who stutter.  Five days of stimulation paired with fluency training increased fluency and brain activity in the striatum compared with fluency training alone.  Finally, I will present our findings from imaging the vocal tract during speech production that indicate instability in the speech motor system in people who stutter during perceptibly fluent speech.

Analysing the prosody of native speakers of Persian in L1 and L2 (English) using the OMProDat corpus

Vendredi 9 décembre 2022, 10h30-12h

LPL, salle de conférences B011

Résumé :
After a brief presentation of our current knowledge of the prosody of the Persian language, this talk focuses on the findings from a bilingual Persian-English prosodic database read by native Persian speakers as part of the OMProDat project. This corpus contains 40 continuous and thematically-connected passages each with five sentences. The collection was read by 5 male and 5 female Persian speakers. Moreover, the ASCII phonetic alphabet SAMPA was used to romanize and phonetically transcribe the Persian sentences. The database includes TextGrid annotations obtained semi-automatically for two speakers (1 male and 1 female) from the sound and the orthographic transcription using the SPPAS alignment software. Then, this part of the corpus was annotated prosodically using the Momel and INTSINT algorithms. Preliminary results of this analysis will be reported in this talk. Using this substantial amount of data, we intend to conduct a cross-linguistic comparison with other languages in OMProDat.

Conceptualisation of old age in English : Interdisciplinary perspective

Vendredi 4 novembre 2022, 10h30-12h

LPL, salle de conférences B011

 

Résumé :

In the present study, I aim to analyse cultural and social constructions of old age and the aged in English. Drawing on the thesis about the interrelation between language and culture, I hypothesize that the concept old age in English is verbalized by a set of socially and culturally loaded representations. This research adopts a cognitive-semantic approach when meaning is defined as conceptualization. It aims at revealing the notional content of the concept old age in English with the focus on the definitions of the lexeme ‘old age’ in present-day lexicographical sources (both printed and on-line). Firstly, the concept of old age as a mental unit and complex knowledge cluster is analysed, its nominative field is defined. It appears to be a multicomponent structure representing the period or time in life when one is old, the person or the group of persons who are old and the state or condition of being old. Secondly, I will highlight the definitions of old age in English and compare different discursive models of ageing conceptualisation. Old age as a social phenomenon is usually defined through the prism of its medico-biological and socio-philosophical characteristics as a final stage of human life with considerable physiological and psychological changes leading to little involvement of a person in social activities. However, the demographic processes of the recent decades have resulted in radical changes in old age delimitation, when it gets measured not only within chronometric framework, but also by sociocultural criteria. Old age as a cultural phenomenon is different from the chronological age, as it is characterized by vague boundaries, the interaction between different age stages, and deviations from their logical order. Furthermore, adopting the interdisciplinary research perspective, the study reveals discursive models of old age conceptualization, providing the description of the new reality of old age not only as a biological phenomenon, but also as a social construct with a complex cognitive structure represented in discourse with normative, axiological, stereotypical, figurative and symbolic components. Moreover, the paper gives insight into the metaphorical conceptualization of old age in the literary discourse and authors’ creative associations about this stage of life.

Key words: old age concept, ageing, conceptualisation, conceptual metaphor, discourse analysis, interdisciplinary approach.
