Many studies have shown that using robot platforms can be effective for teaching children with autism spectrum disorder (ASD). The aim of this study was to compare performance on an imitation task, as well as focus attention levels and the presence of social behaviours of children with ASD and typically developing (TD) children during an imitation task under two different conditions, with robots and human demonstrators. The results suggested that TD children did not imitate more than children with ASD. Children (...) with ASD did not imitate the robot more than they imitated a person, but they showed more focused attention to robots and expressed more social behaviours in interaction with the robots. Behaviours that were significantly more present in ASD children than in TD children included touching the robot in the robot demonstrator condition and focusing on the robot in the person demonstrator condition. This implies a possible preference of children with ASD towards robots rather than towards people. (shrink)
