Perception and Recognition of Objects and Scenes (PROS)

Research Career

  • 2006-2010 : PhD student supported by the National Funds for Scientific Research (FRS-FNRS) of Belgium. Clarifying the nature and the specificity of face recognition mechanisms by means of single-case studies of brain-damaged prosopagnosic patients. Supervisor : Professor Bruno Rossion (UCL, Belgium)
  • 2010-2011 : Postdoctoral fellow supported by the National Funds for Scientific Research (FRS-FNRS) of Belgium. Supervisor : Professor Jason Barton (UBC, Canada)
  • 2011-  : Postdoctoral fellow supported by the National Funds for Scientific Research (FRS-FNRS) of Belgium. Supervisor : Dr Emmanuel Barbeau (CERCO, France)

Research Interests

My PhD concerned the neuropsychological studies of brain-damaged patients suffering from disorders of face recognition (i.e. prosopagnosia). I studied the specificity of face recognition and the nature of perceptual mechanisms involved in face processing. Through several single case studies, I demonstrated that face recognition can be selectively impaired (without any difficulties of processing other objects categories, even when visual similarity is parametrically controlled). I also showed that holistic processing of individual faces is strictly necessary for efficient face recognition. Moreover I studied face familiarity through the studies of two patients for which recognition of personally known faces was investigated.

My current scientific interest is to better understand the cognitive processes underlying familiar faces recognition and access to semantic knowledge for familiar people.

Techniques Used

I’m currently using mainly behavioural studies (with normal people and brain damaged patients).
