To be or not to be trusted: The influence of media richness on defection and deception

When business transactions take place between strangers, individuals rely on the cues during communication to determine whether they can trust others’ intentions. How that process occurs in the context of computer-mediated, video-mediated, and face-to-face interactions is still somewhat unknown. We examine how media richness influences both affective-based and cognitive-based trust in the context of two studies with two different social dilemma scenarios. Further, we explore how these two types of trust influence not only non-cooperative behavior (defection) but also lying (deception). Results from the first study suggest cognitive-based trust mediates the relationship between media richness and defection, while results from both studies suggest that affective-based trust mediates the relationship between media richness and deception. Video-mediated communication solves some, but not all, of the problems inherent when interacting via communication technology.     

罚款对城市居民个人用水行为的影响

以城市居民用水两难情景为实验任务,探讨了处罚（罚款）对城市居民个人用水行为的影响。结果表明：相对只是对违规的个体进行处罚的方式,个体一群体其他成员处罚的方式更能约束人们的不良行为发生相对于现行水价标准,5．4元的超水高额处罚标准很可能是人们的一个心理接受节点,高于该金额的水费处罚标准人们可能将难以接受。     

囚徒选择和中国人的义

通过对囚徒困境博弈的囚徒策略选择发现,中国被试的囚徒策略选择受到中国传统文化中的义的影响：在一次囚徒博弈中,并不像传统博弈论预测的那样被试选择坦白为最优策略,而是有一半多的被试选择了不坦白策略;在进行囚徒选择时大多数被试都意识到了囚徒之间的熟悉关系。囚徒关系被激活后,选择不坦白策略的被试与选择坦白策略的被试之间有显著差异,但性别差异不显著。结果表明,中国传统文化中的“义”以及相应的人际信任是导致被试选择不坦白策略的主要原因。     

When and how communicated guilt affects contributions in public good dilemmas

Two laboratory studies investigated how groups may deal with the strong emotions that social dilemmas often elicit. A first study showed that a new group member evaluated guilt communicated by a fellow group member as more instrumental than neutral emotion feedback when the amount of required resources to obtain the public good (i.e., provision point) was perceived as difficult to obtain. A second study revealed that participants use communicated guilt to draw inferences about both past and future contributions from all fellow group members. Participants also contributed more themselves and adhered to equality more often when guilt versus no emotion was communicated, but only when the provision point was high. Expected contributions from fellow group members mediated this effect.

Which type of leader do I support in step‐level public good dilemmas? The roles of level of threshold and trust

The present research examined the moderating effect of the level of threshold on people's preferences for different leader types in step-level public good dilemmas. It was assumed that the primary focus of people in step-level public good dilemmas is to make sure that the group surpasses the threshold. Consequently, when the level of threshold is difficult to reach people are expected to provide more support for and cooperate with a leader that monitors and controls the contributions made toward the public good. However, if the threshold is easy to surpass people will focus more on whether the obtained public good or bonus will be distributed according to agreements, suggesting that people will provide more support to and cooperate with a leader that monitors and controls the distribution of the bonus. These predictions were confirmed across two experiments using a step-level public good paradigm with a dichotomous (Study 1) and a continuous (Study 2) contribution choice. Moreover, the results also revealed that perceptions of trust accounted, in part, for the effect of level of threshold on people's leadership preferences.     

Moral Utilitarianism and Attitudes Toward Animals

The majority of studies investigating attitudes toward animals have underscored the role of demographic and personality factors. The study of the role of general moral worldviews on attitudes toward animals represents an important complementary perspective. In the current study, we analyzed the relationship between moral utilitarianism toward humans and attitudes toward animals. In psychological and neuroscientific studies, moral utilitarianism has been shown to be related to empathy deficits. We expected that utilitarian decision making would be related to the endorsement of an instrumental representation of animals. We measured utilitarianism with the trolley problem, a hypothetical moral dilemma widely used in the psychological study of moral reasoning. A sample of 20,474 French adults answered an online survey measuring attitudes toward animals and moral decision making involving human beings. Results showed that irrespective of participants’ age and gender, there was a slight relationship between utilitarianism measured by the trolley dilemma and the endorsement of an instrumental representation of animal. Limitations and implications for future research are considered.     

多维Rasch模型在维度分数报告中的应用—对带宽-保真度困境的解决

分别采用四维度和十五维度Rasch模型分析包含项目内多维度结构的科学测验数据,估计两种维度结构下维度分数的信度.结果表明,对比相应的单维模型而言,四维度与十五维度Rasch模型均能够极大提高各内容维度上分数估计的信度.四维度与十五维度Rasch模型拟合结果的比较表明,对于总长度固定的测验,维度数目的增加能够补偿子维度长度减少引起的信度损失.但是这一作用必须以维度间较高的相关性为前提.     

智能医疗的伦理困境与治理——基于以病人为中心的考察

智能医疗的研究与应用发展迅速,在医疗检测、诊断与预测等多领域都显示出了更强的技术优越性。与此同时,智能医疗也出现了算法黑箱导致的病人知情权受到侵犯、用户数据泄露、公平正义问题以及责任归属难以界定等亟待解决的各种伦理难题,对“以病人为中心”的医学临床传统造成威胁。智能医疗的广泛应用不仅需要突破技术难题,更加需要构建以病人为中心的伦理治理体系,做出尊重病人需求和权利的理性决策。
