化身机器人对个体道德两难决策的影响
The Influence of Embodied Robot Avatars on Individuals’ Moral Dilemma Decision-Making
摘要: 具身认知理论认为，认知并非独立于身体和环境而发生，而是在认知、身体与环境的交互中形成。沉浸式虚拟现实(IVR)为探讨身体拥有感错觉如何影响认知提供了重要技术手段。本研究采用单因素被试内设计，通过同步或异步的视觉–动觉多感官刺激操纵被试的身体拥有感。在同步条件下，被试可以自由操控机器人化身，并对机器人产生身体拥有感，从而考察化身成为标准人形机器人后对个体道德两难决策的影响。结果发现，与异步条件相比，同步条件下个体对不作为的普遍偏好(I参数)显著减弱，而结果敏感性(C参数)和规范敏感性(N参数)未受到显著影响。这表明，对标准人形机器人化身产生身体拥有感错觉会促使人们在道德困境中更倾向于采取行动，而非选择不作为。本研究为远程机器人应用与人机交互设计中的道德决策考量提供了实证参考，未来研究可进一步扩大样本，以验证其作用机制。
Abstract: Embodied cognition theory posits that cognition is not independent of the body and environment, but is formed in the interaction among cognition, body, and environment. Immersive virtual reality (IVR) provides a technical means to explore the influence of the body ownership illusion (BOI) on cognition. Using a single-factor within-subjects design (synchronous vs. asynchronous conditions), the present study examined the influence of embodied standard humanoid robot avatars on individuals’ moral dilemma decision-making. In the synchronous condition, participants could freely control the robot avatar and develop a sense of body ownership over it, thereby examining the influence of embodying a standard humanoid robot on individuals’ moral dilemma decision-making. Results showed that the general preference for inaction (I parameter) was significantly reduced in the synchronous condition relative to the asynchronous condition, whereas sensitivity to consequences (C parameter) and sensitivity to moral norms (N parameter) did not differ significantly between conditions. These findings suggest that embodying a standard humanoid robot avatar can weaken individuals’ general preference for inaction in moral dilemmas, providing empirical implications for moral decision-making in teleoperated robot applications and human-robot interaction design. Future research with larger samples is needed to further examine the underlying mechanisms.
