社交机器人用关系型策略更有效劝人少久坐。
Robot-Initiated Social Control of Sedentary Behavior: Comparing the Impact of Relationship- and Target-Focused Strategies
- 对比关系导向与目标导向的劝说策略效果
- 关系型策略让参与者活动时间更长
- 情感联结强的人更易被健康后果说服
为设计能有效促进健康行为改变的社交机器人，需了解人们如何响应其采用的不同健康沟通策略。本研究考察了社交机器人使用的两类社会控制策略：侧重关系后果的关系型策略，以及侧重健康后果的目标型策略，在减少久坐行为方面的有效性。实验在实验室进行，共135名参与者，分两阶段开展：第一阶段参与者与机器人玩游戏，第二阶段机器人使用其中一种策略劝其起身活动。一半参与者参与第二轮重复互动。结果显示，关系型策略显著提升了参与者持续活动的时间；重复互动并未增强参与者对机器人的关系感，但对机器人有更强依恋者，对目标型策略反应更积极。研究为健康传播中社交机器人的说服策略设计提供了重要参考。
原文摘要 · Abstract (English)
To design social robots to effectively promote health behavior change, it is essential to understand how people respond to various health communication strategies employed by these robots. This study examines the effectiveness of two types of social control strategies from a social robot, relationship-focused strategies (emphasizing relational consequences) and target-focused strategies (emphasizing health consequences), in encouraging people to reduce sedentary behavior. A two-session lab experiment was conducted (n = 135), where participants first played a game with a robot, followed by the robot persuading them to stand up and move using one of the strategies. Half of the participants joined a second session to have a repeated interaction with the robot. Results showed that relationship-focused strategies motivated participants to stay active longer. Repeated sessions did not strengthen participants' relationship with the robot, but those who felt more attached to the robot responded more actively to the target-focused strategies. These findings offer valuable insights for designing persuasive strategies for social robots in health communication contexts.
