About

Most studies use static visual percepts that are less representative of joint attention versus an ecological environment. This has the consequence of decreasing the perception of an interaction with a social partner, which is an essential step in achieving joint attention. The originality of this study is to improve the design of visual percepts (in the form of video) in order to mimic an ecological environment as much as possible by using MRI-ET coupling. The second originality of this study is the longitudinal exploration of the neurodevelopment of social cognition in autistic children. Studies by the Redcay and Oberwelland teams observe different activations at different ages. The hypothesis is that the perception of joint attention varies over time in people with ASD. To date, there are no studies to determine the influence of childhood neurodevelopment in autistic people on the perception of joint attention. It would be unprecedented to use the MRI-ET pairing as a tool for assessing social cognition as a function of the development of children with ASD.
