儿童的社会权力认知及其与社会行为的关系

有关成人社会权力认知的研究已有大量的成果及理论, 但儿童的社会权力认知近期才受到关注。社会权力认知是儿童社会认知的重要组成部分。社会权力经常体现在社会支配及社会地位上的差异。从很早开始, 儿童就能基于不同的线索来判断社会权力, 儿童基于这些线索的认知发展有进化上的适应意义。儿童对社会权力获得方式的认知会随年龄增长而发生变化, 年幼儿童更认可基于支配的社会权力获得方式, 而年长儿童更认可基于声望的社会权力获得方式。儿童的社会权力认知会影响选择性信任、资源分配及亲社会行为。未来研究需要考虑影响儿童社会权力认知发展的内部机制以及儿童社会权力对社会行为影响的过程机制, 并考虑文化因素和早期互动经验对儿童社会权力认知发展的影响。     

政治信任:心理学视角下的前因后果

政治信任(Political Trust)是近年来政治心理学和社会心理学研究领域的一个关键变量。研究主要从政治信任的概念、基础理论、特征、测量、相关前因及结果变量的比较及实证研究方面,对国内外相关实证研究进行了梳理与评析。针对现有研究情况,提出未来研究应注意从测量客观性、实验室操纵、相关因素关系、多学科综合研究等方面进一步完善。     

构建医务工作者的诚信体系

医务工作者的诚信体系建设是被全社会普遍关注的一个热点问题。医务工作者的诚信体系应包括几个方面:经济基础是诚信体系的前提和保障;法律规范作为他律控制着医务工作者的诚信;良好的道德环境是构建医务工作者诚信体系的主要手段;个体素质即道德良心是提高医务工作者诚信水平的内在诉求;医疗制度是医务工作者诚信的重要保障。     

Food‐related risk‐reduction strategies: purchasing and consumption processes

Confronted with an alarming social discourse favouring the perception of food risk, modern consumers find themselves in a situation of psychological discomfort caused by consumption of foodstuffs coming from the agricultural and foodstuff industry. To eliminate this discomfort the consumer may change their purchasing and consumption habits (constraining hypothesis) or introduce some measures for the reduction of risk. The aim of this paper is to present a new classification of risk reducers taking into account the diversity of buying and consumption practices. Copyright © 2004 Henry Stewart Publications.     

Antecedents Of Trust: Establishing A Boundary Condition For The Relation Between Propensity To Trust And Intention To Trust

Two studies were conducted to examine the antecedents of intention to trust proposed by Mayer, Davis, and Schoorman [1995, Academy of Management Review, 20(3), 709–734]. In their model, intention to trust is influenced by the perceived characteristics of the trustee and the predisposition of the trustor. We found that perceived ability, benevolence, and integrity of the trustee predicted an individuals intention to trust. Propensity to trust, that is, an individuals disposition to trust, correlated with intention to trust when information about trustworthiness was ambiguous, but did not correlate with intention to trust when information about trustworthiness was clear. The notion of strong and weak situations is used to argue that situational strength is a boundary condition of the relation between propensity to trust and intention to trust.     

HIV Infection and the Central Nervous System: A Primer

The purpose of this brief review is to prepare readers who may be unfamiliar with Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome (HIV/AIDS) and the rapidly accumulating changes in the epidemic by providing an introduction to HIV disease and its treatment. The general concepts presented here will facilitate understanding of the papers in this issue on HIV-associated neurocognitive disorders (HAND). Toward that end, we briefly review the biology of HIV and how it causes disease in its human host, its epidemiology, and how antiretroviral treatments are targeted to interfere with the molecular biology that allows the virus to reproduce. Finally, we describe what is known about how HIV injures the nervous system, leading to HAND, and discuss potential strategies for preventing or treating the effects of HIV on the nervous system.     

Preference for human or algorithmic forecasting advice does not predict if and how it is used

Past research has found that people treat advice differently depending on its source. In many cases, people seem to prefer human advice to algorithms, but in others, there is a reversal, and people seem to prefer algorithmic advice. Across two studies, we examine the persuasiveness of, and judges' preferences for, advice from different sources when forecasting geopolitical events. We find that judges report domain-specific preferences, preferring human advice in the domain of politics and algorithmic advice in the domain of economics. In Study 2, participants report a preference for hybrid advice, that combines human and algorithmic sources, to either one on it's own regardless of domain. More importantly, we find that these preferences did not affect persuasiveness of advice from these different sources, regardless of domain. Judges were primarily sensitive to quantitative features pertaining to the similarity between their initial beliefs and the advice they were offered, such as the distance between them and the relative advisor confidence, when deciding whether to revise their initial beliefs in light of advice, rather than the source that generated the advice.     

Investor's Pessimistic and False Belief About Trustworthiness and Stake Size in Trust Decision1

Trust is a vital element of any society. Previous studies using trust games have provided insight into understandings of trusting behavior. However, investors' behaviors can be confounded by their risk preferences in the game, and little is known about the relationship between stake size and beliefs of others' good intentions underlying trust. We thus used a variant of the trust game and conducted two experiments to examine how stake size affects investors' beliefs about receivers' trustworthiness, with model-based analyses. We showed that, when holding all else equal, investors trusted more, but their expectations of reciprocation declined as stake size increased. However, actual receivers' reciprocation rates showed the opposite trend to investors' pessimistic beliefs. Furthermore, following previous studies in social psychology, we hypothesized that investors' social preferences (social value orientation) moderated the beliefs underlying trust, but they had no explanatory powers in investors' expectations of reciprocation. These results suggest that peoples' naive beliefs about stake size play a more important role in trust decisions than expected.     

Explaining the procedural justice–perceived legitimacy relationship: Relying on relational concern or instrumental concern?

People can extract relational information (i.e., relational concern) as well as instrumental information (i.e., instrumental concern) from decision‐making procedures. Thus, both instrumental and relational concerns are assumed to influence the procedural justice–perceived legitimacy relationship. Drawing from social exchange theory, the different kinds of concerns may lead to form different exchange relationships (social exchange relationship vs. economic relationship), which can be indicated by two forms of trust (affect‐based trust vs. cognition‐based trust). We built a model of trust mediation in which procedural justice predicted affect‐based and cognition‐based trust. Further, we also tested the hypothesis that high (compared with low) group identification individuals are more likely to rely on relational concern to construct procedural justice and judge legitimacy of authority, because they use procedural fairness information to infer the quality of their relationships with the authority. The results of an experiment (Study 1) demonstrated that both affect‐based trust and cognition‐based trust mediated the procedural justice–perceived legitimacy relationship. Moreover, a field study (Study 2) showed that affect‐based trust mediated the relationship between procedural justice and perceived legitimacy primarily among individuals with high group identification whereas cognition‐based trust mediated this relationship primarily among those with low group identification.
