About this trial
The goal of this observational study is to evaluate intra-individual neurophysiological variability in children and adults with and without NeuroDevelopmental Disorders (NDD), for several sensory modalities and types of stimulation. The main hypotheses are:
* NDD participants and children exhibit higher intra-individual variability than other participants * intra-individual neurophysiological variability is correlated to behavioral, psychological and learning profiles
Participants in this study will:
* be recorded for EEG and other neurophysiological parameters while exposed to sensory stimulations, to quantify sensory neurophysiological variability * perform behavioral tests and fill out questionnaires, to establish the behavioral and psychological profile * train for perceptual learning, to measure learning abilities
These evaluations will be split in 3 visits spread on a maximum of 3 months, and training for learning will be done at home in between 2 visits.
