NAO Robot, Transmitter of Social Cues: What Impacts?

The Example with “Endowment effect”
Conference paper
Part of the Lecture Notes in Computer Science book series (LNCS, volume 10350)


Assuming that social norms are engaged in all human-human interactions in an automatic manner, how to program a robot as to activate respect of social norms from humans? We argue that endowment effect, constituting a bias in decision making, could be produced by a “politeness effect” within the exchange paradigm of Knetsch (1989). To test this hypothesis, NAO, a humanoid robot took the place of the human experimenter and was programmed to behave in a neutral way, annihilating all non-verbal social cues emission. In this condition, politeness rules had been respected by minority in contrast with the same methodology lead by a human. Following this experiment, NAO was programmed as to re-activate social norms, using several non-verbal social cues: face tracking, intonations of voice and gestures. First results in this way tend to show the impact of non-verbal social cues, producing an endowment effect again.
