社交网络游戏中互惠合作的轻量级交互
Lightweight Interactions for Reciprocal Cooperation in a Social Network Game
摘要：
互惠关系的建立需要在最初的会议期间进行合作互动。然而，与陌生人的合作行为是有风险的，因为陌生人可能是剥削者。在这项研究中，我们表明，人们增加了合作的可能性，陌生人使用轻量级的非风险的互动，在危险的情况下，基于分析的社会网络游戏（SNG）。他们可以通过这种方式建立互惠关系。交互涉及低成本的信号，因为它们不是以任何成本生成的。理论研究表明，低成本信号并不能保证可靠，因为来自发送者的低成本信号随时可能撒谎。然而，人们使用低成本信号来构建SNG中的互惠关系，这表明在人类进化中存在产生可靠，低成本信号的机制。
英文摘要：
The construction of reciprocal relationships requires cooperative interactions during the initial meetings. However, cooperative behavior with strangers is risky because the strangers may be exploiters. In this study, we show that people increase the likelihood of cooperativeness of strangers by using lightweight non-risky interactions in risky situations based on the analysis of a social network game (SNG). They can construct reciprocal relationships in this manner. The interactions involve low-cost signaling because they are not generated at any cost to the senders and recipients. Theoretical studies show that low-cost signals are not guaranteed to be reliable because the low-cost signals from senders can lie at any time. However, people used low-cost signals to construct reciprocal relationships in an SNG, which suggests the existence of mechanisms for generating reliable, low-cost signals in human evolution.
