Brain scans probe how autistic minds handle the unexpected

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: For non autistic individuals * Affiliation with social security scheme. * Registration in the national database of individuals willing to participate in research involving human subjects. * Absence of contraindications for MRI. * Signed informed consent before any study-related procedure. * Visual acuity allowing normal perception of stimuli or corrected vision. * Autism Quotient (AQ) (Baron-Cohen et al., 2001) \< 32. For autistic individuals: * Affiliation with social security scheme. * Absence of contraindications for MRI. * Signed informed consent before any study-related procedure. * Visual acuity allowing normal perception of stimuli or corrected vision. * Diagnosis of autism established by a competent professional based on DSM/ICD criteria. Exclusion Criteria: * Any subject with a vascular stent implanted less than 6 weeks before the examination. * Any subject with implanted biomedical material deemed "unsafe" or "not safe" in the list: http://www.mrisafety.com/TheList\_search.asp. * Any acquisition procedure not meeting the conditions required for "conditional" use in subjects with implanted biomedical material classified as "conditional" in the list: http://www.mrisafety.com/TheList\_search.asp. * Any subject with biomedical material such as a cardiac, neuronal, or sensory stimulator (cochlear implant due to the risk of demagnetization, heating, electrode, and artifacts) or a ventricular shunt valve without medical and paramedical supervision trained in MRI performance in these subjects. * Intraocular or intracranial ferromagnetic foreign body near nerve structures (risk of displacement and complications such as ocular or cerebral lesions). * Claustrophobia - Psychiatric or neurological conditions other than those specified. * Existence of a severe general health condition incompatible with the study: cardiac, respiratory, hematological, renal, hepatic, or cancerous. * Alcohol ingestion before the examination. * Persons covered by articles L1121-5 to L1121-8 of the Public Health Code (pregnant or breastfeeding women, minors or adults under legal protection, individuals under administrative or judicial surveillance). * Visual impairments. * Intellectual disability. * Inability to understand research instructions or provide informed consent.
