The behaviour of shedding tears is a unique human expression of emotion. Human tears have an emotional signalling function that conveys sadness and a social signalling function that elicits support intention from others. The present study aimed to clarify whether the tears of robots have the same emotional and social signalling functions as human tears, using methods employed in previous studies conducted on human tears. Tear processing was applied to robot pictures to create pictures with and without tears, which were used as visual stimuli. In Study 1, the participants viewed pictures of robots with and without tears and rated the intensity of the emotion experienced by the robot in the picture. The results showed that adding tears to a robot's picture significantly increased the rated intensity of sadness. Study 2 measured support intentions towards a robot by presenting a robot's picture with a scenario. The results showed that adding tears to the robot's picture also increased the support intentions indicating that robot tears have emotional and social signalling functions similar to those of human tears.
流泪行为是人类独特的情感表达方式。人类的眼泪具有传达悲伤的情感信号功能和引发他人支持意图的社会信号功能。本研究旨在使用先前针对人类眼泪所开展研究中采用的方法，阐明机器人的眼泪是否具有与人类眼泪相同的情感和社会信号功能。对机器人图片进行眼泪处理，以创建有泪和无泪的图片，并将其用作视觉刺激物。在研究1中，参与者观看有泪和无泪的机器人图片，并对图片中机器人所体验到的情感强度进行评分。结果表明，给机器人图片添加眼泪会显著提高悲伤程度的评分。研究2通过呈现带有场景的机器人图片来测量对机器人的支持意图。结果表明，给机器人图片添加眼泪也会增加支持意图，这表明机器人眼泪具有与人类眼泪相似的情感和社会信号功能。
