In my research I have been focusing on the acquisition of linguistic and social skills in infants. I am also interested in the consequences of early acquisitions in adults, in particular on the more or less reversible specialization of cognitive processes for a particular language or culture. My approach is to run comparative studies in adults and infants, and constrain theories of adult and infant speech processing by proposing theoretical models that take into account both types of studies. Specifically, I am involved in the following three areas:
- Phonological 'deafnesses' in speech perception: acquisition and plasticity.
Infants can learn effortlessly one or several languages at the same time. Yet, adults, have a hard time acquiring a second language. Why? In this project, we investigate the hypothesis that part of the difficulties are due to an early specialization and subsequent lack of plasticity of perceptual processes after a certain critical age.
We test this hypothesis by conducting experiments on the development of phonological categories during the first year of life, and on perception and production in monolingual and bilingual adults. We use psycholinguistic methods, as well as brain imagery (ERPs, fMRI). The issue of the residual functional plasticity for language is also studied in neurological patients with language impairement.See the summary of the main results in:
- Modeling early language acquisition.
The developmental landmarks of language acquisition during the first years of life have been well described but the mechanisms underpinning them remain poorly understood. The complexity of learning problem that infants face is daunting: he or she has to acquire, mostly without supervision, several interdependant aspects of language simultaneously: phonology, morphology, syntax, semantics.
The aim of this project is to aply machine learning and signal processing techniques (bayesian models, HMM, etc.) to corpora of child-adult verbal interactions and develop unsupervized algorithms which can extract phonological categories (syllables, phonemes, features). These algorithms are then tested in infants or newborns using either behavioral techniques or noninvasive brain imagery (Optical Topography, EEGs).See the summary of the main results in:
- Modelling phonological acquisition (in preparation) [PDF]
- Dupoux. E. (2009). How Do Infants Bootstrap into Spoken Language?: Models and Challenges. ICML, McGill, June 2009. [video lecture]
- The development of social cognition.
Humans have unique abilities to help, communicate, and cooperate with their conspecifics. Correlatively they also have a high propensity to cheat, defect and harm their conspecifics. It is therefore plausible that we have adaptative mechanisms devoted to the quick evaluation of the actions and dispositions of other humans. Here, we study the biological, developmental and psychological bases of these implicit social evaluations mechanisms and the role they play in the emergence of explicit cultural systems of social and moral norms.
We conduct experiments in infants, toddlers, adults, and patients using animated cartoons showing characters that perform prosocial or antisocial actions towards conspecifics. We test the social evaluation of these characters and the inferences that are drawn from them using a variety of explicit and implicit measures.See the summary of the main results in:
