最近对人类合作机制的理解主要集中在信任的概念上，研究表明，最初的印象和之前的互动都会影响人们对伴侣的信任度。然而，关于这两种类型的信息在迭代交换中是如何相互作用的，人们知之甚少。本研究考察了在重复信任博弈中，内隐初始信任度信息与经验信任度之间的相互作用。与我们的假设一致，这两个因素既独立又协同地影响行为，无论是玩家愿意将多少钱托付给他们的伴侣，还是他们在比赛后对可信度的主观评级。为了进一步了解这种相互作用，我们使用强化学习模型来测试几个不同的加工假设。这些结果表明，可信度是一种关于互惠概率的信念，最初基于内隐判断，然后根据经验动态更新。这项研究提供了一个新的量化框架来概念化可信性的概念。(C)2010 Elsevier Inc.保留所有权利。
Recent efforts to understand the mechanisms underlying human cooperation have focused on the notion of trust, with research illustrating that both initial impressions and previous interactions impact the amount of trust people place in a partner. Less is known, however, about how these two types of information interact in iterated exchanges. The present study examined how implicit initial trustworthiness information interacts with experienced trustworthiness in a repeated Trust Game. Consistent with our hypotheses, these two factors reliably influence behavior both independently and synergistically, in terms of how much money players were willing to entrust to their partner and also in their post-game subjective ratings of trustworthiness. To further understand this interaction, we used Reinforcement Learning models to test several distinct processing hypotheses. These results suggest that trustworthiness is a belief about probability of reciprocation based initially on implicit judgments, and then dynamically updated based on experiences. This study provides a novel quantitative framework to conceptualize the notion of trustworthiness. (C) 2010 Elsevier Inc. All rights reserved.
