Multidisciplinarity in cognitives sciences/language sciences
The heart of the PCMD team's research concerns the study of the relationship between oral language and the cognitive processes that ensure its functioning. The cohesion of the team is based on the disciplinary complementarity of its members (CNRS sections 07, 26 and 34; CNU sections 07, 16, and 61; ED EDISCE and LLSH) around a common theoretical framework in cognitive sciences and language, granting us autonomy for experimentation, data processing and modeling.
A characteristic of the team is to study speech as anchored in the reality of the body that produces it, and located in a context of interaction with an interlocutor. All the projects developed in the team share this question: how anatomical/physiological, neurophysiological and situational constraints affect or even structure the cognitive processes of production and perception of oral language and spoken communication in the broad sense, not only in adults, but also during development in children, and in children and adults with speech disorders.
These questions are addressed by crossing experimental methods (behavioral recording including Babylab, motion capture, EMG, TMS, sensory disturbances, brain imaging, EEG, MEG, fMRI) with computational modeling (signal processing, control theory, Bayesian models , AI).
The research of the team is structured in 3 axes:
- Sensorimotor control of speech
- The cognitive processes of encoding and decoding speech
- Communication in face-to-face interaction.
Two orientations are more particularly under development:
- on the one hand around the computational modeling of the cognitive processes described above (particularly in the context of the Speech Chair of the Multidisciplinary Institute of Artificial Intelligence MIAI);
- on the other hand in clinical phonetics with the double aim of better understanding the cognitive processes of speech in their pathological dimension, and of providing data and knowledge for the diagnosis and treatment of various speech and communication disorders.
