In the field of memory, our metacognitive abilities, i.e. our ability to evaluate and predict our memory performance, are clearly the result of a progressive adjustment. For example, we have shown that early childhood is characterised by a highly optimistic increase in memory capacity. This is only modulated when the child is confronted with reality. It is not until adolescence that our metacognition approaches real performance.
We are also exploring metacognition in various neurological pathologies in collaboration with the CMRR at Grenoble University Hospital.

The general challenge is the improvement of fundamental learning in elementary school, namely reading and oral English. The objectives of the TRANS3 project are 1) to finalize the development of the applications created and evaluated within the framework of the FLUENCE project so that they are resolutely adapted to classroom use; 2) to allow them to be widely and sustainably disseminated in French-speaking schools, including those in the departments of Guyana and Mayotte; 3) to promote and support their use in the classroom by creating educational guides, training and additional resources for teachers; 4) to test their usability/acceptability in classes, as well as the impact of their use on student progress and on teachers’ teaching practices; 5) to consolidate the scientific knowledge associated with these tools and disseminate them on a large scale in the teaching world, in order to anchor the evolution of educational practices on theoretical frameworks and solid scientific data. These ambitious objectives will be made possible thanks to the continued collaboration of all the authors of the FLUENCE applications with new university partners, but also with the inclusion in the consortium of a digital publisher (HumansMatter) and an educational publisher. (Éditions Hatier), each having solid experience in their field of expertise and determined to collaborate to achieve these objectives. They will participate in the creation of the tools, ensure their promotion and dissemination on a large scale and beyond the project, according to an economic model that is transparent for all stakeholders. The commitment of the rectorates of Grenoble, Mayotte and Guyana guarantees the participation of these academic territories in the evaluation of the impacts linked to the use of the applications. This project will fit into the favorable framework of the Pégase pilot center (PIA3 funding, pilot center for teacher training and research for education). The first year will essentially be devoted to the co-construction, with a few user-tester teachers integrated into the team, of all the necessary tools: version 1 of the applications, the teacher interface, additional resources and content and training materials. Year 2 will allow us to test the effectiveness and usability of these tools in a set of diverse schools, to continue to adapt them as best as possible to practice and to refine the means of dissemination. The scientific research initiated in FLUENCE will also continue throughout the duration of the project and will be promoted in publications and training for teachers. The wide use of the 3 applications in French-speaking schools should contribute to the improvement of educational differentiation practices and the reading and English skills of students.

In Grenoble, the LPNC (Body and Space team), in collaboration with the GIPSA-Lab (COPERNIC team), we are developing the AdVIS System, a virtual prototype allowing you to reach a target object without vision. The prototype is built on a choice of spatial metrics accessible from an artificial sensor, to be matched with a choice of percepts initiated by sound and tactile stimuli. The effectiveness and comfort of the human-machine interfacing resulting from these choices are tested on typical participants (blindfolded) mainly in a controlled environment, in the laboratory and virtually. In a hot-cold game, they seek to hit a 3-D virtual target in a motion-captured space. The deviations in angle and/or distance from this target are sent in real time according to the position of the index finger seeking to aim and then touch the target

At the University of Normandy, CERREV (Caen) in collaboration with LITIS (Rouen) are developing a tactile belt which indicates through vibrations on the skin around the user's waist their position in relation to beacons placed on their path .

In Palaiseau, the CMAP of the Polytechnique school is developing spatialized sound algorithms making it possible to place a "flying" sound source in front of the person's head as a virtual guide such as a "Tinkerbell" or "Navi" fairy. This fairy replaces a human assistant who normally runs in front of her in the corridor of an athletics stadium track. The culmination of this 24-month project is a festive disabled sports event modeled on the “Laser Run”, which is two combined modern pentathlon events. The person (blind, or deprived of vision) who runs on a circuit, approaches a shooting station with a table on which he must find and take in hand a laser gun, to shoot three times at a target before resume, possibly in relay, the rest of his race on the circuit. Performance requires coordination of the systems developed in the three sites. The main issue is not a hypothetical immediate improvement in the living conditions of these people, but a leisure activity; in fact, competitive play is a situation which stimulates the development of devices, then adapted to everyday life. 

At NU, we guide a person along markers using a tactile belt At UGA, we guide by sound towards a 3D virtual target In Saclay, we guide a person on a racing circuit using spatial sound Bottom: Coordination will allow in Laser Run (modern pentathlon), without eyes, to run on a circuit, find the weapon, aim at the target...

Rasmussen encephalitis is a chronic autoimmune disease characterized by progressive unilateral hemispheric atrophy. This pathology causes drug-resistant partial epilepsy and is accompanied by progressive, disabling neurocognitive disorders. Due to its drug resistance, the only curative treatment is hemispherotomy, a functional disconnection between the hemispheres. Given the young age of surgery, patients with Rasmussen are expected to benefit from significant brain reorganization that allows significant recovery of cognitive functions, even if it occurs unevenly, depending on the specific developmental trajectories of these functions. and individual cognitive and cerebral reserve. In addition to the cognitive recovery observed in adulthood, different models of brain reorganization have also been described. Therefore, it is of particular interest to understand the strategies recruited by these patients due to neuroplasticity. Overall, this research project aims to evaluate both the cognitive outcome and the reorganization of brain networks in adult patients with Rasmussen encephalitis after hemispherotomy performed during childhood. A multimodal approach will be used, combining experimental psychology and neuropsychology to assess a wide range of cognitive functions (language, executive functions, theory of mind and memory) and clinical scores, as well as fMRI in resting state and DTI-MRI to measure the connectivity of functional and structural networks of the functional hemisphere, respectively. The originality of this work also consists of the development of a new multi-cognitive battery specifically adapted to this population (LEXTOMM, Perrone-Bertolotti, M., 2021). We thus wish to improve our understanding of patients with Rasmussen encephalitis by describing cognitive and cerebral phenotypes, with new directions for cognitive rehabilitation and pre-habilitation to ensure their best possible recovery.

The Pégase center aims to transform teaching practices from kindergarten to high school to strengthen the learning of fundamental knowledge (oral and written language, mathematics/computer science, respect for others) and thus contribute to reducing social, territorial and social inequalities. cognitive. The Center was designed as an ecosystem closely associating the laboratories of UGA and USMB, the INSPE and Rectorates of Grenoble and Guyana, and the entire teaching community. This ecosystem is collaborative, distributed, open and learning. It works to place the “evidence-basededucation” approach at the heart of the initial and continuing training of teachers, to promote their professional development by relying on data from research.

L’imagerie par résonance magnétique fonctionnelle (IRMf) est devenue un outil essentiel pour évaluer l’activité neuronale liée aux fonctions cognitives. La majorité des études d’IRMf comprennent de petits ensembles de données, ce qui empêche d’appliquer de nouvelles approches pour l’analyse des données telles que l’intelligence artificielle (IA), et plus particulièrement les réseaux neuronaux convolutifs (CNN) qui nécessitent de grands ensembles de données pour atteindre une efficacité optimale. Le CNN est une méthode d’IA incluse dans l’apprentissage profond (DL), un type d’apprentissage automatique (ML) qui imite la façon dont les humains acquièrent des connaissances. L’apprentissage par transfert (TL) est récemment apparu comme une solution couramment utilisée pour surmonter la rareté des données d’IRMf tout en utilisant l’apprentissage profond. Le TL peut être réalisé grâce à des modèles pré-entraînés pour extraire des caractéristiques afin de répondre à une tâche particulière. L’objectif de notre projet est de développer un modèle générique pré-entraîné pour l’analyse de données IRMf, entraîné sur de grands ensembles de données, pour réaliser la TL. Nous proposons une approche basée sur un transformeur entraîné avec les valeurs de l’activité des voxels IRMf. Un pipeline utilisant un CNN 3D pour extraire les caractéristiques spatiales des données IRMf 4D, suivi d’un transformateur alimenté par les données enchâssées résultant du CNN pour modéliser l’aspect temporel des données, sera développé

Art-Science-Parenting Project

Funded by IDEX UGA Scientific and Cultural Outreach, in the wake of a previous project launched in 2017 and entitled “The Languages of Babylab”, Languages and Music of Babylab articulated scientific research and artistic creation to resonate the research of artists and scientists from Grenoble working on the development of language and communication in infants. Scientifically, he proposed evaluating the impact of musical interventions on infant language development. On an artistic level, the artists engaged in creative research nourished by interactions with babies. Finally, in terms of parenting, families participated in discussions with artists and scientists to discuss and understand the links between music, language and awareness. Thanks to the mediation of the Mediarts association, the project made it possible to establish links between artists and researchers and to forge long-term partnerships with early childhood stakeholders.

RÉALISATIONS
- 91 artistic residency sessions in 9 different Isère territories with 4,446 audiences. - 10 concert-workshops bringing together 995 spectators, including events as part of Brain Week 2020, rescheduled for the 2022 edition. - 1 professional training “Creation and imaginary language at the service of little ones” conducted today by the Training Center for Performing Musicians (Université Lumière Lyon 2)
