以前的工作表明，手势行为影响拟人推理的人工通信，如虚拟代理。在一个人形机器人的实验中，我们研究了手势在多大程度上会影响机器人的拟人推理。特别是，我们研究了机器人的手和手臂的姿态对典型的人类特征，机器人的可爱性，共享的现实，和未来的接触意图与机器人互动后的归属的影响。为此，我们在三个实验条件下操纵仿人机器人的非语言行为：（1）没有手势，（2）一致的手势，和（3）不一致的手势。我们假设在两个手势（与没有手势）条件下，所有相关措施的评分更高。结果证实了我们的预测：当机器人在交互过程中使用手势时，它被更多地拟人化，参与者认为它更讨人喜欢，报告了更多的共享现实，并且显示出比机器人在不使用手势的情况下给出指令时更多的未来接触意图。令人惊讶的是，当机器人的手势与语音部分不一致时，这种效果尤其明显。这些研究结果表明，在机器人系统中的交流非语言行为影响拟人化的看法和心理模型的人形机器人在互动过程中形成的人。
Previous work has shown that gestural behaviors affect anthropomorphic inferences about artificial communicators such as virtual agents. In an experiment with a humanoid robot, we investigated to what extent gesture would affect anthropomorphic inferences about the robot. Particularly, we examined the effects of the robot's hand and arm gestures on the attribution of typically human traits, likability of the robot, shared reality, and future contact intentions after interacting with the robot. For this, we manipulated the non-verbal behaviors of the humanoid robot in three experimental conditions: (1) no gesture, (2) congruent gesture, and (3) incongruent gesture. We hypothesized higher ratings on all dependent measures in the two gesture (vs. no gesture) conditions. The results confirm our predictions: when the robot used gestures during interaction, it was anthropomorphized more, participants perceived it as more likable, reported greater shared reality with it, and showed increased future contact intentions than when the robot gave instructions without using gestures. Surprisingly, this effect was particularly pronounced when the robot's gestures were partly incongruent with speech. These findings show that communicative non-verbal behaviors in robotic systems affect both anthropomorphic perceptions and the mental models humans form of a humanoid robot during interaction.
