What mechanisms help infants and children process speech when it is degraded? Are these mechanisms the same for infants and children with typical hearing and those with hearing loss? How do hearing devices affect these speech processing mechanisms? The aim of my research is to investigate these questions using both behavioural and neural perspectives.

Ongoing project

Linking early phonolexical acquisition and later vocabulary development

In this project, we test the proposal that a crucial milestone in language acquisition is reached when infants discover which sounds (consonants versus vowels) are more important at the lexical level in their native language, leading to an acceleration of subsequent vocabulary development.

Development of the auditory system and speech perception in infants- BabySIN 

On the one hand, the cerebral processing of different acoustic variations of sounds is studied in 3-month-old infants using the electroencephalography technique. On the other hand, the ability to perceive speech in noise in these infants is measured using an observation technique.

Proccesing phonological information while learning and recognizing words

It has been proposed that consonants carry more weight than vowels in lexical processing. Given the timing of acquisition observed in French, we have proposed that this consonant bias emerges in connection with phonological and (proto)lexical acquisition, a hypothesis we are currently testing.

Predicting language outcomes in typical development

We explore how elementary perception and learning mechanisms are linked to language acquisition. To this end, we test infants on different perception and learning mechanisms, at different stages of their development and up to 2-3 years of age.

Language acquisition in atypical development

Knowing the mechanisms underlying typical language acquisition also makes it possible to explore whether or not these mechanisms are present in populations with atypical language acquisition and could be involved in their learning difficulties.

Lexical-semantic development

Our studies aim to understand the neural mechanisms underlying this development in monolingual and bilingual children.
