The need to understand trust in groups holistically has led to a surge in new approaches to measuring collective trust. However, this construct is often not fully captured in its emergent qualities by the available research methods. In this paper, the Collective Trust Game (CTG) is presented, a computer-based, multi-agent trust game based on the HoneyComb paradigm, which enables researchers to assess the emergence of collective trust. The CTG builds on previous research on interpersonal trust and adapts the widely known Trust Game to a group setting in the HoneyComb paradigm. Participants take on the role of either an investor or trustee; both roles can be played by groups. Initially, investors and trustees are endowed with a sum of money. Then, the investors need to decide how much, if any, of their endowment they want to send to the trustees. They communicate their tendencies as well as their final decision by moving back and forth on a playfield displaying possible investment amounts. At the end of their decision time, the amount the investors have agreed upon is multiplied and sent to the trustees. The trustees have to communicate how much of that investment, if any, they want to return to the investors. Again, they do so by moving on the playfield. This procedure is repeated for multiple rounds so that collective trust can emerge as a shared construct through repeated interactions. With this procedure, the CTG provides the opportunity to follow the emergence of collective trust in real time through the recording of movement data. The CTG is highly customizable to specific research questions and can be run as an online experiment with little, low cost equipment. This paper shows that the CTG combines the richness of group interaction data with the high internal validity and time-effectiveness of economic games.
整体理解群体信任的需求导致了新的集体信任测量方法的激增。然而，现有的研究方法往往无法充分捕捉到这一结构的涌现特性。本文提出了一种基于 HoneyComb 范式的计算机多主体信任游戏，即集体信任游戏（CTG），该游戏使研究人员能够评估集体信任的涌现。CTG 建立在人际信任的先前研究基础上，并将广泛使用的信任游戏改编为 HoneyComb 范式中的群体设置。参与者扮演投资者或受托人；这两个角色都可以由群体担任。最初，投资者和受托人被赋予一笔钱。然后，投资者需要决定他们想要将其捐赠额的多少（如果有的话）发送给受托人。他们通过在显示可能投资金额的游戏场地上来回移动来表达自己的倾向和最终决定。在他们的决策时间结束时，投资者同意的金额会被乘以并发送给受托人。受托人需要通过在游戏场地上移动来表达他们想要返还多少投资，如有返还的话。这个过程会重复多轮，以便通过反复互动形成共享的集体信任。通过这个过程，CTG 通过记录运动数据，提供了实时跟踪集体信任的出现的机会。CTG 可以根据具体的研究问题进行高度定制，并且可以作为在线实验运行，所需设备简单且成本低廉。本文表明，CTG 结合了群体互动数据的丰富性与经济游戏的高内部有效性和时效性。
