Research Theme

Le langage est une fonction cognitive complexe, impliquant le traitement de plusieurs niveaux interconnectés de structure linguistique (par ex., phonologie, syntaxe, sémantique). L’objectif de nos recherches est de comprendre les mécanismes (neuro-)psychologiques sous-jacents au traitement du langage par les adultes et à son acquisition rapide par les nourrissons et les jeunes enfants. Notre équipe comprend quatre chercheurs indépendants, qui focalisent sur différents aspects du traitement et de l’acquisition du langage: Anne Christophe, Emmanuel Chemla, Alex Cristia, et Sharon Peperkamp (cliquez sur les noms pour visiter les pages web individuelles). Notre stratégie de recherche intègre de l’expertise en linguistique formelle, psychologie expérimentale, neuroimagerie, et modélisation computationnelle.

Covert speech production in infants

Chercheur responsable: 

CHRISTOPHE Anne

Dates: 

1 September 2016 - 31 December 2016

Date limite de candidature: 

1 September 2016

~ Sep-Dec 2016 ~ Jan-March 2017 ~ Apr-June 2017

Project:

Towards the end of their second year of life, infants typically understand several dozen words, but pronounce very few of them. Using an innovative training paradigm based on anticipatory eye-movements, we have shown that they can covertly produce words (“inner speech”) that they do not yet overtly pronounce, and, moreover, categorize them as short or long. In this project, we will use the same paradigm but with a different categorization task to further investigate the representation of words in infants’ covert speech production.

Perceptual learning of speech sounds

Chercheur responsable: 

CHRISTOPHE Anne

Dates: 

1 September 2016 - 31 December 2016

Date limite de candidature: 

1 September 2016

~ Sep-Dec 2016 ~ Jan-March 2017 ~ Apr-June 2017

Project:

Adult listeners rapidly adapt to non-standard pronunciations of sounds in their native language. For instance, when exposed to a list of words in which the sound /s/ is replaced by a sound that is perfectly ambiguous between /s/ and /f/, they will shift their perceptual boundary between /s/ and /f/, such that their /s/-category becomes larger and their /f/-category smaller. In this project, we will examine the limits on this type of spontaneous perceptual learning.
