Developing trust: First impressions and experience

Using the repeated Trust Game, we investigated how first impressions and experience affect trusting dispositions, beliefs, and behaviors. As in previous research, trusting beliefs and trust-related behaviors were greater at the start of the game for partners with trustworthy faces; and higher later in the game for partners who reciprocated. Three additional findings extended beyond the previous research. First, by measuring the discrete components of trusting beliefs rather than an umbrella “trustworthiness” measure, we confirmed that first impressions and experience influence judgments of competence, benevolence, and integrity. Moreover, we found suggestive evidence that perceptions of benevolence and integrity updated more quickly with experience than perceptions of competence. Second, by looking at trusting beliefs at the start of two consecutive repeated Trust Games, we found that judgments of competence, benevolence, and integrity continue to be influenced by trustworthy facial appearances, even after previous beliefs based on facial appearances were disconfirmed. Third, we found increased investment with a partner at the start of a second repeated Trust Game, even when participants expected their partners to betray them. Overall, our results clarify our understanding of how first impressions and experience influence trusting beliefs; provides evidence that changes in the repeated Trust Game represents learning about a specific partner rather than revisions of trusting dispositions; and highlights important distinctions between trusting beliefs and trust-related behaviors.

表面相似性与标签效应对儿童数概念发展的影响

为考察表面相似性与标签效应对3～6岁儿童数概念发展的影响，采取等量匹配任务和数量比较任务考察儿童数概念的发展情况，并通过给数取物，给物取数和等量匹配与数量比较任务的关系考察儿童使用数字标签的能力对儿童数概念形成与发展的影响。结果表明：5岁儿童基本可以完成等量匹配和数量比较任务；表面相似性效应与儿童数概念的发展没有显著的相关；数字标签能够促进儿童数概念的发展。     

大沽路“约辩”事件背后的教育利益博弈检视

大沽路"约辩"事件的背后是不同教育利益主体间的利益博弈。教育利益博弈局面的形成是由于当前中国的社会阶层固化、优质教育资源稀缺、户籍制度改革滞后以及教育的功利化等原因所造成的。要使教育利益博弈格局得以缓释和平衡,需要整合与协调各教育利益主体的利益需求,打破阶层固化以实现社会阶层之间的合理流动,以务实的精神和魄力实现一种宏阔的教育公平以及实现教育精神价值的回归和教育理想的再确认。     

Trust responsiveness. On the dynamics of fiduciary interactions

Trust and trustworthiness are key elements, both at the micro and macro level, in sustaining the working of modern economies and their institutions. However, despite its centrality, trust continues to be considered as a “conceptual bumblebee”, it works in practice but not in theory. In particular, its behavioural rationale still represents a puzzle for traditional rational choice theory and game theory. In this paper “trust responsiveness”, an alternative explanatory principle that can account for trustful and trustworthy behaviour, is proposed. Such principle assumes that people can be motivated to behave trustworthily by trustful actions. The paper discusses the philosophical roots, the historical development, as well as the relational nature of this principle as well as its theoretical implications.
