Individual Neurophysiological Sensory Profiles in People With and Without Neurodevelopmental Disorders

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.

Inclusion Criteria: * Social security affiliation * Free and written informed consent from the participants (Neurotypical Adults, NDD Adults without judicial protective measures), or their tutor or legal representant(s) (other participants) * Age between 6 and 12 years included (Children) or between 18 and 45 years included (Adults) * For NDD participants: NDD diagnosis by a qualified medical professional, according to DSM-4, DSM-5, ICD-10 or ICD-11 criteria Non-inclusion Criteria: * Psychotropic medication perturbing EEG recording * Drugs pertubing peripheral neurophysiological measures * Non-corrected visual or auditory troubles * Known neurological or psychiatric conditions (at the exclusion of NDD for NDD participants) * Epilepsy * Inclusion in another ongoing medical protocol * For Neurotypical participants: NDD diagnosis * For NDD participants: anticipated psychological or physical risk at participating, at the investigator's discretion Exclusion Criteria: * Participants with no data to evaluate Outcome 1
