TL;DR
This paper explores how social power strategies can enhance the persuasive ability of social robots, demonstrating that certain power bases increase compliance and influence human decision-making effectively.
Contribution
It introduces a novel application of social power theory to robot persuasion, supported by three user studies showing the effectiveness of specific power bases.
Findings
Robots using expert, reward, and coercion power bases are more persuasive.
Social rewards can effectively persuade individuals.
The influence of social power on persuasion does not diminish over time.
Abstract
Can social power endow social robots with the capacity to persuade? This paper represents our recent endeavor to design persuasive social robots. We have designed and run three different user studies to investigate the effectiveness of different bases of social power (inspired by French and Raven's theory) on peoples' compliance to the requests of social robots. The results show that robotic persuaders that exert social power (specifically from expert, reward, and coercion bases) demonstrate increased ability to influence humans. The first study provides a positive answer and shows that under the same circumstances, people with different personalities prefer robots using a specific social power base. In addition, social rewards can be useful in persuading individuals. The second study suggests that by employing social power, social robots are capable of persuading people objectively to…
