 This trial will test the efficacy of robot-enhanced interventions for developing social skills in children with Autism Spectrum Disorders ASD. The study will compare, in an equivalence design, an innovative intervention delivered by a semi-autonomous robotic agent with standard behavioral intervention. The target group is children between 3 and 6 years old which will be randomly allocated to one of the two treatments. Each treatment will be delivered over 8 bi-weekly sessions of 45 minutes each.
