  • Thesis subject : The predictive brain framework to understand and help people with autism spectrum conditions.

Abstract : Many theoretical frameworks have tried to explain autism characteristics but have failed to unify all symptoms (Sapey- Triomphe, 2017). However, predictive coding could be a new framework with which to understand the autism phenotype, i.e. social characteristics, specific interests and stereotyped behaviors as well as sensory specificities, but also the variability which exists from one individual to another (Gomot & Wicker, 2012 ; Sinha et al., 2014 ; Van de Cruys et al., 2014). This framework postulates an imbalance in weights allowed to bottom-up (from perception to cognition) versus top-down processes during perception in autistic people. The Bar model (2007) showed that low spatial frequencies (LSF) of images are extracted very quickly and projected onto the orbitofrontal cortex, where they enable prediction (top-down process) on what is perceived (included prediction on facial expression). In autism spectrum conditions, there is, on one hand, difficulties in facial emotion recognition (Uljarevic & Hamilton, 2013) and on the other hand, a local perceptual bias in vision (Mottron, Dawson, Soulières, Hubert, & Burack, 2006). Local information of a visual stimulus is carried by high spatial frequencies (HSF) ; on the contrary, global information is carried by low spatial frequencies. Some research has studied spatial frequencies utilization during face processing in autism and this population seems to use preferentially HFS (Deruelle, Rondan, Gepner, & Tardif, 2004). Despite these data, top-down prediction (guided by LFS and passing by the orbitofrontal cortex) have not been studied in autism spectrum conditions. The aim of this thesis is to study predictive brain in autistic people, and more specifically, to study LSF processing during visual perception of emotional ad non emotional stimuli.
