Persuasion Strategies Using a Social Robot in an Interactive Storytelling Scenario

Abstract

The behaviour of a person in a given situation can be explained understanding his personality traits. In this sense, the identification of these traits can be a great value to achieve personalised social influence. Although there are several models of persuasion, few of them take into account the person's personality traits. For this reason, this work describes a persuasion study that takes into account a person's personality. We develop a storytelling decision-making scenario, where the participant receives influencing messages to follow a pattern of behaviour determined by a persuasive agent (an autonomous social robot with assertive behaviour). From the study, we find evidence that the model used within the proposed scenario managed to make participants more engaged in the activity. We found pieces of evidence that the levels of assertiveness of a person can influence their attitude and perception by an agent. Also, we identify that persuasion strategy which uses persuasive arguments are more efficient than strategies that have no arguments. Finally, our proposed persuasion strategies have achieved a good level of successful influence.

“…Moreover, it is well-known that not all individuals are affected similarly by the same persuasion technique [Moyer-Gusé 2008]. Therefore, discovering the most effective way to subtly influence a person without their realization is crucial [Paradeda 2020]. In our work, we programmed the agent to persuade participants using a combination of facial expressions and emotions.…”

A Storytelling Robot Managing Persuasive and Ethical Stances via ACT-R: An Exploratory Study

“…Since storytelling is an embodied activity deeply based on the use of gestures and postures, sto-rytellers robots are often proposed instead of virtual agents, most commonly for educational purposes with the result of a greater engagement [41], [66], [57], [21], [9]. Storytelling robots have been also used to raise and foster awareness about sensitive themes [13], and to influence behaviour [55], [56]. In particular, starting from the assumption that the success of a persuasion strategy depends on a reference target group, Paradeda et al implemented in a robot a persuasion model based on a categorization of humans personality traits, with the aim to influence the listener in choosing the actions to perform according to a story plot [55], [56].…”
