This project investigates a question fundamental to social and economic interactions: Can individuals accurately assess the trustworthiness of unfamiliar others and, if so, through what mechanisms? Decisions to trust constitute a necessary element for the development of stable partnerships and societies. Yet, in the face of the many benefits that come with delayed exchanges, the decision to trust another is often a precarious one. The individual who first extends effort or provides resources is necessarily in the unenviable position of risking that the other will not reciprocate. Consequently, adaptive functioning relies not only on trusting others, but also on the ability to decide if one's partner is worthy of trust. Interestingly, however, previous efforts designed to uncover the signals of trustworthiness have been relatively unsuccessful. Building off initial research by members of the project team which demonstrates that trustworthiness of new partners can be discerned at greater than chance levels, the current project explores a novel route by which individuals may assesses the intentions of potential partners. Rather than looking for specific cues to trustworthiness in isolation, the process of assessing trust will be reconceptualized as a dynamic and iterative one. In short, the project will examine whether decisions to trust are not based simply on reading the cues of others, but rather on a dynamic "dance" whereby partners engage in nonconscious mimicry, and in so doing, are able to use perceptions of their own bodily states to infer their partner's feelings and, thereby, predict their motivations. To investigate this possibility, the research team will conduct experiments examining the interplay of emitted nonverbal signals and mimicry on decisions to trust within the context of behavioral economic games. Moreover, given that many facets of these phenomena often occur outside of human awareness and control, newly developed social robots will be used as interaction partners for humans in several experiments. These robots provide not only exacting control over relevant expressive parameters that is not possible in humans, but also the opportunity to test proposed models by allowing the robot to predict the trustworthiness of human partners. Taken as a whole, this project not only holds potential to increase understanding of the processes the underlie the initial emergence of trust-based relationships, but also to refine the physical and computational architecture that enable robots to infer motives and predict actions of humans and, thereby, increase their utility and value as interaction partners.

这个项目研究了社会和经济互动的一个基本问题：个人能否准确地评估不熟悉的人的可信度，如果可以，通过什么机制？信任的决定是发展稳定的伙伴关系和社会的必要因素。然而，面对延迟交换带来的诸多好处，信任他人的决定往往是一个不确定的决定。第一个付出努力或提供资源的人必然处于不令人羡慕的境地，因为他冒着别人不会回报的风险。因此，适应性功能不仅依赖于信任他人，还依赖于判断伴侣是否值得信任的能力。然而，有趣的是，之前旨在揭示可信度信号的努力相对来说是不成功的。项目团队成员的初步研究表明，新合作伙伴的可信度可以在高于偶然水平的情况下被识别，目前的项目探索了一种新的途径，通过这种途径，个人可以评估潜在合作伙伴的意图。评估信任的过程将被重新定义为一个动态和迭代的过程，而不是孤立地寻找可信度的具体线索。简而言之，该项目将研究信任的决定是否不是简单地基于对他人暗示的解读，而是基于一种动态的“舞蹈”，在这种“舞蹈”中，伴侣无意识地模仿，从而能够通过对自己身体状态的感知来推断伴侣的感受，从而预测他们的动机。为了研究这种可能性，研究小组将在行为经济博弈的背景下进行实验，研究发出的非语言信号和模仿对信任决策的相互作用。此外，鉴于这些现象的许多方面经常发生在人类意识和控制之外，新开发的社交机器人将在几个实验中用作人类的互动伙伴。这些机器人不仅提供了对人类无法实现的相关表达参数的严格控制，而且还提供了通过允许机器人预测人类伴侣的可信度来测试所提出模型的机会。作为一个整体，这个项目不仅有潜力增加对基于信任的关系最初出现的过程的理解，而且还可以改进物理和计算架构，使机器人能够推断动机和预测人类的行为，从而增加它们作为互动伙伴的效用和价值。
