Researchers have found that offline consolidation of a motor task was enhanced by praise delivered by robots, whether they were presented on a screen or were physically present. Further, simultaneous praise from two agents had a stronger effect than praise from just one, regardless of whether the agents were physically present or virtual. Such effects could be helpful for facilitating education and for general enhancement of human-robot interactions.
