Evidence for Implicit Risk: Delay Facilitates the Processing of Uncertainty

Humans and other animals discount the value of rewards over time. One explanation for this is that delayed rewards may be less certain than immediate rewards, what has been referred to as the implicit risk hypothesis. Although this explanation is widely accepted, little research has directly assessed the validity of the implicit risk hypothesis. In the current study, we present two experiments in which participants made decisions about rewards involving both delay and uncertainty. By manipulating the order in which information was presented, we were able to investigate whether delay information facilitates beliefs about uncertainty and vice versa. It was found that participants were more likely to prefer larger, delayed rewards when information about delay was presented before information about uncertainty than when the information was presented in the opposite order. Additionally, we describe a process model that implements the implicit risk hypothesis and show that it is consistent with the observed patterns of data. These results support the implicit risk hypothesis and suggest that information about delay facilitates the processing of information about uncertainty. Copyright © 2015 John Wiley & Sons, Ltd.     

Effect of Romantic Relationship on Implicit Regional Prejudice

The study measures both the implicit regional prejudice and the explicit simple attitude of 93 students of five universities in China, either involved or not in different stages of a romantic relationship and at varying distances from their partners, by using the Brief Implicit Association Test and Explicit Reports. Results indicate that close relationships can contribute significantly to decreasing implicit regional prejudice. Further studies are needed to provide support for the causal mechanism between interpersonal relationships and changes in social attitudes. Copyright © 2014 John Wiley & Sons, Ltd.     

Mirror,mirror, on the wall,who is the most masculine of them all? The Dark Triad,masculinity, and women’s mate choice

Although the Dark Triad of personality (i.e., Machiavellianism, narcissism, and psychopathy) has been researched widely, few studies have looked at women’s preferences for men who are high and low in Dark Triad. Further, it is not clear what the relationships between the Dark Triad and facial masculinity are. We investigated female preference for computer manipulated Dark Triad male faces in two on-line studies (Study 1: n = 125; Study 2: n = 1633). We found that women rated the high psychopathy and narcissistic faces the most masculine (Study 1). We also found that women showed a low preference for the high morphs in both long and short term relationships, and that preference for masculinity was correlated with a preference for narcissism (Study 2). We discuss the results in terms of male and female mating strategies.     

追随力认知图式:概念解析与整合模型

追随力认知图式是一种历经社会化,以抽象表征形式储存于个体记忆中的关于追随力的认知结构,亦称为追随原型。领导者的追随原型通常在领导—追随互动中被激活,并与部属实际追随力进行匹配。匹配失败的追随原型将被重新归类或定义,匹配成功的追随原型将通过领导者的态度和行为影响追随者的职业幸福感、角色内绩效和角色外行为。人格、市场行情、组织结构和文化能预测追随原型。未来可加强多水平效应、匹配效应和生物基础的探讨。     

Will commute drivers switch to park-and-ride under the influence of multimodal traveler information? A stated preference investigation

The knowledge about en-trip mode switching behavior with presence of multimodal traveler information is very limited so far. This study investigated the impacts on commute drivers’ en-trip mode switch decisions of smartphone multimodal traveler information systems (SMTIS) which integrate dynamic information of auto-drive and subway park-and-ride (P&R). This is based on data collected from a stated preference survey in Shanghai, China. A panel mixed probit model which accounts for potential correlations of observations among a same driver and heterogeneity in preferences for travel time savings and comfort level of subway car was developed. The panel model has a much better goodness of fit than a model without consideration of panel effect and heterogeneity. The results show that SMTIS have significant impacts on commuter drivers’ decision about switching from auto drive to P&R; the impacts depend on personal attributes including gender, age, education level, income, and P&R use experience; the sensitivity to time savings in the case non-incident induced delays, and the sensitivity to comfort level of subway, both vary significantly among the driver sample.     

内隐和外显测量对利他行为的预测:来自IAT和BIAT的证据

利他行为是指人们自愿付出一定代价做出的有益于他人的行为。该研究以联结性-推理性评价模型为理论基础探讨内隐和外显测量对利他行为的预测效度,研究以193名大学生为被试,将4种内隐利他测量方法和1种外显利他测量方法相结合,以自发性水平不同的3种利他行为为结果变量。结果发现,IAT和BIAT的信度和效度较好,BIAT尤其值得采用。内隐利他自我概念测量能有效地预测真实情境中自发性较高的捐助行为,外显测量则预测了意识控制下自我报告的利他行为。结果表明,只有内隐利他自我概念测量能预测真实情境中快速发生的利他行为。其作用是外显利他测量和内隐利他态度测量所不能代替的。     

Values Voters: The Conditional Effect of Income on the Relationship Between Core Values and Political Attitudes and Behavior

The postmaterialism thesis contends that newer cultural and social justice issues will supplant traditional, class‐based economic concerns as societies become increasingly wealthy. Although macrolevel evidence broadly supports this prediction, individual‐level evidence for the theory in the United States has been sparse. Moreover, alternative theories predict that postmaterialism will not travel well to the American context because religious cleavages that divide the major parties will be most salient. We test the postmaterialism thesis at the individual level using unique data that enable us to evaluate citizens' value‐preference structures across income levels, as well as the conditional effect of income on the relationship between individuals' ranked value preferences and political attitudes and behavior. Consistent with the theory, greater income strengthens the association between egalitarianism and ideology, partisanship, evaluations of President Obama, and presidential vote choice, and weakens the relationship between moral traditionalism and these same variables. However, income does not moderate the association between economic security and individuals' identities, evaluations, or behavior. Additionally, value‐preference hierarchies are quite similar across income groups after controlling for partisanship and ideology. The results lend insight into the nature of value‐ and income‐based cleavages in American politics.     

Two flaws concerning belief accounts of implicit biases

The current scientific discourse offers two opposing viewpoints about the roots of implicit biases: are they belief states or subdoxastic attitudes? The goal of this paper is to show that belief accounts of implicit biases are (1) too demanding and (2) lack a satisfying reasoning theory. Firstly, I will outline the concept of attitude and its relation to implicit biases. Next, I will briefly outline Mandelbaum’s view, who gives a paradigmatic example of a belief account of implicit biases. Afterward, I will concern two flaws and discuss them in more detail. This shows that all current belief accounts of implicit biases do not emphasize these critical points enough, which makes them unsatisfying.
