Understanding Children’s Trust Development through Repeated Interactions with a Virtual Social Robot

Studies in Child-Robot Interaction have shown that children form first impressions of a robot’s trustworthiness that might influence how they interact with social robots in long-term interactions. However, how children’s trust in robots evolves and how it relates to relationship formation is not well understood. This study investigates the effects of repeated encounters with a virtual social robot on children’s social and competency trust in social robots and their relationship formation. We developed an online storytelling game with the Furhat robot, where 25 children (9-12 years old) played with the robot over two sessions with seven days of zero exposure in between. Results show that children’s competency trust improved with time. We also found empirical evidence that children felt closer to the robot in the second encounter. This work enriches the scientific understanding of children’s trust development in social robots over extended periods of time in child-robot collaborative interactions.
