Mapping the Cognitive Model for Single-Word Processing onto Brain Dynamics

Background: The human brain can process single words during different tasks and via different modalities. We can hear the word ‘apple’ and repeat it out loud, or we see the word written on a page and read it, or we think of its concept, or see an image of it, and name it out loud. These three tasks (word repetition, reading and naming) require different computations at early stages, but share others at higher, amodal, levels.

Externalisation et réalisme de sources sonores en réalité virtuelle/augmentée

Le son émis par une source réelle est normalement perçu comme « externalisé », c’est-à-dire comme provenant de l’environnement autour de l’auditeur. Par contre, les sources reproduites au casque sont en général perçues comme « internalisées », le son semblant alors provenir de l’intérieur de la tête. La reproduction audio binaurale permet d’externaliser des sources sonores simulées au casque.

Auditory cognition and neuronal processing

Our research focuses on the neuronal basis of auditory cognition, exploring how contextual factors influence auditory processing at the cortical level. We use ferrets as a key model to bridge our understanding of human cognition. We explore how ferrets process complex sounds, including speech,, how attention shapes perception, and how early auditory experiences shape cortical development. By leveraging electrophysiology and functional ultrasound neuroimaging, we aim to uncover parallels between ferret and human auditory processing, with applications to attention, learning, and memory.

Perceiving environmental unnaturalness

The internship is under to supervision of Christian Lorenzi (LSP) and Sacha Bourgeois-Gironde (IJN) We are seeking a highly skilled M2 student with a strong background in analytic philosophy and a serious interest in environmental philosophy and sciences for an internship on the topic of "Perceiving Environmental Unnaturalness." Internship objective: The primary aim of this internship is to map the dual concepts of "naturalness" and "unnaturalness" as they are discussed in both philosophical and scientific literature.

Infants’ developing lexicon

During the first year of life, infants develop word segmentation capacities and start storing segmented word candidates in a ‘protolexicon’. Previously, we showed that their sensitivity to statistical information leads them to include in this protolexicon frequently occurring non-word strings in addition to real words.

Infants' acquisition of word segmentation

Words are a central building block of language, and segmenting words out of continuous speech is a challenging step in early language acquisition. Indeed, in spoken language there is no acoustic equivalent to the spaces that separate words in written language: spoken words are not separated by pauses. Infants start developing word segmentation abilities during the first year of life, relying on their sensitivity to both phonological and syllable co-occurrence cues to word boundaries.

Dyslexia: towards a new treatment?

Can reading performance of dyslexic readers be improved with auditory rhythmic training? A key ingredient for reading is the mapping of graphemes (letters) to phonemes (sounds). Thus, correct representation of speech sounds is critical for reading. At the same time, rhythmic brain activity seems to be crucial for language comprehension. In that way, comprehension is hindered when there is deficient alignment between brain rhythms and rhythms of perceived speech.
