不确定性风险选择的抱负水平—相对效用整合理论

本文认为不确定性风险决策备择方案的选择标准既不是规范效用理论所主张的效用最大化,也不只是研究者们基于西蒙有限理性决策理论而提出的抱负水平,而是存在于决策不同阶段上的、由启发式策略控制着的这两种标准的整合,我们称之为抱负水平－相对效用整合标准。为此,我们在研究抱负水平结构的基础上提出了负险选择的抱负水平－相对效用整合理论及其支持性研究证据,并就有关问题进行了讨论与思考。指出抱负水平－相对效用整合是风     

How does green advertising skepticism on social media affect consumer intention to purchase green products?

Underpinned by the stimulus–organism–response model, this study explores the underlying mechanism through which green advertising skepticism on social media affects consumer green purchase intention. It also investigates the boundary factors that moderate this indirect relationship. Performing structural equation modeling on data collected from an online survey on Sina Weibo, this study finds that green advertising skepticism on social media negatively affects green purchase intention through the mediation of perceived information utility. Moreover, interdependent self‐construal positively moderates, and independent self‐construal negatively moderates this indirect relationship. These findings suggest that truthful and consumer‐tailored green advertising is crucial to green product marketing.     

How mindfulness affects benign and malicious envy from the perspective of the mindfulness reperceiving model

At present, mindfulness is a hotspot in psychological research. Mindfulness is an effective tool that enables people to effectively inhibit negative emotions. Previous studies have shown that envy is a typical negative emotion; however, envy can be divided into two completely different types: benign envy and malicious envy. The question then arises, how does mindfulness affect both types of envy? Using a mindfulness reperceiving model, we explored the effect of mindfulness on these two different types of envy and on the mediating mechanism of psychological resilience. To accomplish this, we recruited 676 Chinese undergraduates to complete the Mindful Attention Awareness Scale (MAAS), the Benign and Malicious Envy Scale (BEMAS) and the Connor-Davidson Resilience Scale (CD-RISC). The results we obtained showed that mindfulness and psychological resilience significantly and negatively predicted malicious envy and that psychological resilience played a partially mediating role in the relationship. In addition, the results showed that there was no significant effect between mindfulness and benign envy; however, psychological resilience can significantly and positively predict benign envy and played a completely mediating role between mindfulness and benign envy. These results effectively extend theories based on the mindfulness reperceiving model while also being important for promoting benign envy and inhibiting malicious envy in terms of improving mindfulness and psychological resilience.     

信任以稀为贵?下属感知被信任如何以及何时导致反生产行为

感知被信任是信任相关研究中的重要组成部分, 近年来逐渐受到研究者们的重视。以往研究大多认为, 下属感知被上司信任对下属自身以及组织整体都会产生积极影响, 却忽视了其潜在的负面影响。基于自我评价理论, 本文采用实验研究(研究1、2)与多时间点、多源的实地问卷调查(研究3), 探讨了下属感知被信任的潜在黑暗面。研究结果表明：下属感知被信任会引发下属心理权利感, 进而增加其反生产行为, 下属感知到信任的稀缺性在这一过程中起调节作用。具体来说, 当下属感知到信任的稀缺性较高时, 下属感知被信任通过心理权利感影响其反生产行为的正向中介效应显著; 而当下属感知到信任的稀缺性较低时, 上述中介效应不显著。本研究发现了感知被信任的潜在负面影响, 并明确了其对反生产行为的作用机制与边界条件, 为感知被信任相关研究提供了更加全面、辩证的研究视角, 同时也扩展了心理权利感和反生产行为的相关研究。     

父母教养与MAOA基因rs6323多态性对学前儿童外化问题的共同作用

采用G×E交互作用的研究范式,以295名学前儿童（M=4.49）和其母亲、父亲作为研究对象,探讨母亲和父亲的教养方式与MAOA基因rs6323多态性对学前儿童外化问题行为的影响。结果发现：母亲、父亲教养方式和MAOA基因多态性对学前儿童外化问题行为的影响存在性别差异,预测男孩外化问题行为时,母亲和父亲教养方式的主效应显著,与MAOA基因多态性的交互作用不显著;在预测女孩外化问题行为时,父亲教养方式的主效应显著,母亲教养方式与MAOA基因多态性的交互作用显著,显著性区域分析发现,携带T等位基因的女孩更容易受到母亲消极教养的不利影响而产生更多外化问题行为,也更容易受到其积极教养的有利影响而减少外化问题行为,这一结果支持差别易感性理论模型。     

新时期抵御境外宗教渗透的几点思考

随着改革开放和经济建设的不断深入,特别是加入世界贸易组织以后,我国与世界各国经济、文化交往日渐频繁,宗教方面对外交往亦日益增加,境外敌对势力加紧了利用宗教对我国进行渗透的活动。因此,抵御境外势力利用宗教进行渗透活动,是宗教工作面临的一项十分重要的任务。一、“境外宗教渗透”的内涵境外宗教渗透是指境外团体、组织和个人利用宗教从事的各种违反我国宪法、法律、法规和政策的活动和宣传。主要有两方面的情况:一是境外敌对势力利用宗教作为渗透的工具,打着宗教旗号颠覆我国政权和社会主义制度,破坏国家统一和民族团结;二是企图控…     

Pigeons (Columba livia) learn to link numerosities with symbols

After responding to each element in varying, successive numerosity displays, pigeons (Columba livia) had to choose, out of an array of symbols, the symbol designated to correspond to the preceding number of elements. After extensive training, 5 pigeons responded with significant accuracy to the numerosities 1 to 4, and 2 pigeons to the numerosities 1 to 5. Several tests showed that feedback tones accompanying element pecks, the familiarity of element configurations, and the shape of the elements were not crucial to this performance. One test, however, indicated that the number of pecks issued to the elements was important for numerosities above 2. An additional test confirmed that the birds chose the symbol that corresponded to a particular numerosity rather than the positions that the symbols had held during training.     

汉语字谜原型激活中的情绪促进效应

采用先学习原型字谜、接着进行正负情绪诱导、然后再进行靶字谜测验的三阶段实验设计,探讨了不同诱发情绪状态对汉语字谜原型激活的影响。结果发现,在本实验条件下：难度高的靶字谜的测试中没有发现正负诱发情绪状态对汉语字谜原型激活的不同影响;但是,在难度中等的靶字谜的测试中,诱发的正面情绪状态对汉语字谜原型激活有显著促进作用,而诱发的负面情绪状态与控制组相比对汉语字谜原型激活没有显著影响。性别变量在两种实验条件下都没有显著主效应
