Abstract
Atypical neural architecture causes impairment in communication capabilities and reduces the ability of representing the referential statements of other people in children with autism. During a scenery of “speaker–listener” communication, we have analyzed verbal and emotional expressions in neurotypical children (n = 20) and in children with autism (n = 20). The speaker was always a child, and the listener was a human or a minimalistic robot which reacts to speech expression by nodding only. Although both groups performed the task, everything happens as if the robot could allow children with autism to elaborate a multivariate equation encoding and conceptualizing within his/her brain, and externalizing into unconscious emotion (heart rate) and conscious verbal speech (words). Such a behavior would indicate that minimalistic artificial environments such as toy robots could be considered as the root of neuronal organization and reorganization with the potential to improve brain activity.

Notes
Heart rate is measured in beat per minute (bpm) using a frequency counter ring (electronic device) placed on the index finger of each child. The physiological heart rate limits correspond to 95 bpm (±30) at the age of 6–7 years.
