This research is a case-control study aiming to characterize motor peculiarities (objective quantitative and qualitative measures) and its psycho-physiological correlates of children with ASD.

The main objective is to measure jointly and in an automated and standardized manner the performance and motor patterns within the framework of tasks measuring the performance and patterns of general motor skills (postures, walking, coordination overall), fine motor skills (graphics, pointing task) and oculomotricity (visual orientation and control).

The secondary objective is to investigate the relationships between motor difficulties and cognitive and social disorders found in children with ASD.

• Compare the motor performance data in the 3 major motor domains with each other (overall, fine and oculomotor);
• Evaluate intergroup differences based on clinical characteristics (ADOS-2, ADI-R, CARS 2 scores), age, IQ, socio-communication profile score (SRS-2) and presence comorbidities (TADH, TDC).
