我们报告了一项实验，该实验研究了拟人化和感知代理对虚拟环境中存在、共同存在和社会存在的影响。实验改变了互动者形象的拟人化程度：高拟人化、低拟人化或无拟人化。通过告诉参与者图像要么是由人类控制的化身，要么是由计算机控制的代理，来操纵感知代理。研究结果支持了人们对人类和计算机控制的实体都有社交反应的预测，并且虚拟图像的存在增加了远程临场感。与没有拟人化图像或拟人化图像的参与者相比，与拟人化程度较低的参与者互动的参与者报告了更多的出现和社会存在感，这表明拟人化图像越高，期望越高，当这些期望得不到满足时，他们的存在感就会降低。
We report on an experiment that examined the influence of anthropomorphism and perceived agency on presence, copresence, and social presence in a virtual environment. The experiment varied the level of anthropomorphism of the image of interactants: high anthropomorphism, low anthropomorphism, or no image. Perceived agency was manipulated by telling the participants that the image was either an avatar controlled by a human, or an agent controlled by a computer. The results support the prediction that people respond socially to both human and computer-controlled entities, and that the existence of a virtual image increases telepresence. Participants interacting with the less-anthropomorphic image reported more copresence and social presence than those inter-acting with partners represented by either no image at all or by a highly anthropomorphic image of the other, indicating that the more anthropomorphic images set up higher expectations that lead to reduced presence when these expectations were not met.
