Research interests :

I carry out my research in the lab CLLE UMR 5263, LTC Team, axis 1 : Cognitive Ergonomics : memory, rhythms, ageing 

My research domain is the study of the auditory categorization and skills. The hypothesis is that we organize our perception by categorisation to learn and to organise our sound world. 

This categorisation seems to be dynamic (it is not fixed by a training, but varies according to needs), cognitive driven, and the objective of action depends very directly on task, and of action goal.

My studies concern three types of auditory stimuli: speech, music and environmental sounds. They are principally based on the theory of prototype and typicality, developed by Rosch (1976) and taken back in France by Dubois (1991).

With objective to answer this hypothesis, I collaborate on some studies in several domains:

  • studies with non-deaf and deaf people, children and adults, with cochlear implant, to understand their perception of environmental sounds.
  • studies on various type of stimuli (music and soundscapes) to understand auditories skills to perform a task or to build our environmental world by auditory indices.
  • studies on the understanding (and the difference with intelligibility) of speech, and its applications in industrial domain.

The experimentation using the prototype categorization theory require experimental paradigms ad hoc. It is for it that I develop since 2003 experimental software TCL-LABX.

The research in auditory skills also need adapted technological facilities, that is why I use the "Cognition, Behaviour and Use" facilities (CCU) including a set in audition (audiometric cabin).
