I have a general interest in the development and the plasticity of the face recognition system.
An important paradox characterizes the development of the face recognition system. Whereas newborns already show a great deal of face processing abilities, the face recognition system is known to be fully matured only at puberty. Within this developmental perspective, we focus on the development of holistic face processing abilities testing newborns and children.
On the one hand, I have conducted a study with newborns in collaboration with Prs. F. Simion and C. Turati (University of Padova, Italy) which addresses the question of newborns’ abilities to process different spatial frequency ranges on face stimuli (see Cognition paper below). Using the habituation technique, we found that newborns’ face recognition was based on spatial frequencies below 0.5 cycles per degree, indicating that they rely preferentially on aspects of a face that deal with large rather than subtle variations provided by fine details.
A second experiment testing 4-, 5-, 6-year-old children and adults on the composite face illusion suggested that holistic face processing is mature at 4 years of age and is stable between 4 and 6 (see JECP paper below). It was also interesting to note that fixation sites and eye movements were virtually identical in adults when the top and bottom parts were aligned (composite illusion) or misaligned (no illusion), indicating that holistic face processing can be independent of gaze behavior (see Journal of Neuropsychology paper below).
During my PhD under the supervision of Bruno Rossionat the University of Louvain, I studied the plasticity of the face recognition system by investigating the potential environmental influences on the system when it is still developing (children) and fully matured (adults). I also took part in event-related potential studies in children.
Between 2009 and 2011, I did a postdoc at McMaster University, with Daphne Maurer.
