Resource scarcity aggravates ingroup bias: Neural mechanisms and cross-scenario validation

Previous studies examining the relationship between ingroup bias and resource scarcity have produced heterogeneous findings, possibly due to their focus on the allocation of positive resources (e.g. money). This study aims to investigate whether ingroup bias would be amplified or eliminated when perceived survival resources for counteracting negative stimuli are scarce. For this purpose, we exposed the participants and another confederate of the experimenters (ingroup/outgroup member) to a potential threat of unpleasant noise. Participants received some ‘relieving resources’ to counteract noise administration, the amount of which may or may not be enough for them and the confederate in different conditions (i.e. abundance vs. scarcity). First, a behavioural experiment demonstrated that intergroup discrimination manifested only in the scarcity condition; in contrast, the participants allocated similar amounts of resource to ingroup and outgroup members in the abundance condition, indicating a context-dependent allocation strategy. This behavioural pattern was replicated in a follow-up neuroimaging experiment, which further revealed that when contrasting scarcity with abundance, there was higher activation in the anterior cingulate cortex (ACC) as well as stronger functional connectivity of the ACC with the empathy network (including the temporoparietal junction and medial prefrontal cortex) for ingroup compared to outgroup members. We suggest that ACC activation reflects the mentalizing process toward ingroup over outgroup members in the scarcity condition. Finally, the ACC activation level significantly predicted the influence of resource scarcity on ingroup bias in hypothetical real-life situations according to a follow-up examination.     

Stop the blame game: An analysis of blaming on Weibo during the early days of the COVID-19 pandemic in rice and wheat areas in China

In the pandemic era, social media has provided the public with a platform to make their voice heard. One of the most important public opinions online during a pandemic is blame. Blame can lead to stigma towards patients as well as potential patients and decrease social cooperation, which might impede prevention and control measures during epidemics. Thus, studying online blame during the early days of COVID-19 can facilitate the management and control of future pandemics. By analyzing 3791 posts from one of the most popular social media sites in China (Weibo) over the 10 days immediately after COVID-19 was declared to be a communicable disease, we found that there were four main agents blamed online: Individuals, corporations, institutions, and the media. Most of the blame targeted individual agents. We also found that there were regional-cultural differences in the detailed types of blamed individual agents, that is, between rice- and wheat-farming areas in China. After controlling influence of distance from the epicenter of Wuhan, there were still stable differences between regions: people in wheat areas had a higher probability of blaming agentic, harmful individuals, and people in rice areas had a higher probability of blaming individuals with low awareness of social norms for preventive health behavior. Findings have implications for preventing and predicting blame across cultures in future pandemics.     

计算机控制心理学实验过程的计时误差分析

计算机在控制心理学实验过程中,可能引入各种潜在的计时误差,特别在短时呈现各种实验刺激时,有些误差是不应忽略的。本文重点分析屏幕刷新率对实验设计的限制及可能产生的计时误差和解决方法。     

入手术室时的情绪状态和某些心理、生理机能的联系及其和针麻效果的关系

情绪活动和某些生理机能或心理过程的关系很久以来就已进行过大量的研究。外科手术前患者的情绪状态及其相应的生理机能的变化,也曾受到注意。患者在意识清醒状态下进行针麻手术,他的情绪状态对针麻过程及其效果的作用如何,这种情绪状态和某些心理、生理机能有什么联系?这是针麻临床上和理论上应予探讨的问题之一。本工作试图综合分析患者的情绪状态和与之伴随的某些生理生化指标变化,以探讨     

心理恐惧的背后

我受雇于闹市区一家金店已有十多年之久,在过去那是绅士贵族们经常光顾的地方,金店门前的地毯上,踩上去的全是那些个脚面上打着光腊,像镜子一样透出主人潇洒风姿的昂贵皮鞋印痕。现在的情形可是与十多年前不再一样,尽管金银首饰还是那么昂贵,购买者已经不仅仅是绅士富姐,多了出双入对的情侣,赚了钱的私人企业家,爱美心切的普通人。这些金家的姊妹们,芳名金戒指、金项     

主观阶层研究取向的贡献与弊端

近年来社会阶层心理学研究领域对于主观阶层的研究取向高度重视,突出表现为强调社会阶层概念中的主观阶层成分,在理论阐述、概念测量、研究设计和研究问题选择上都倾向于关注主观阶层。这一取向为社会阶层心理学的发展奠定了基础,也扩展了该领域的研究方法及关注问题的视野。但它也造成了部分研究在理论层面与社会现实有所脱节、在概念层面过于忽视客观阶层、在方法层面过于依赖操纵主观阶层,以及在问题层面只关注高低二元阶层划分、对现实阶层多样性关注不足等弊端。未来应进一步深入开展基础研究以厘清客观阶层和主观阶层的关系及其不同的预测效应,在研究设计时对于客观阶层和主观阶层进行更细化的区分,同时可以更多关注于现实中的具体社会问题。     

视觉空间伪忽视与表征伪忽视神经机制的异同

伪忽视是指个体存在的轻微偏左的不对称空间注意,而视觉空间伪忽视和表征伪忽视是其两种主要表现形式。研究初期,研究者认为两种伪忽视基于相同的注意定向左偏机制,但近年来研究发现,它们存在神经机制的差异。本文主要从两种伪忽视神经机制的异同出发,梳理近期研究结果,以期增进对伪忽视的理解。未来研究可以从认知时间进程角度或设计更为完善的研究范式进一步探讨这两种伪忽视神经机制的异同。     

自尊与人际互动：理论、研究与问题

基于自我确认理论开展的大量研究,有助于理解自尊对人际互动行为的调节作用。然而,研究者对自尊的测量工具不尽相同,筛选实验被试的标准也不尽一致,实验范式忽略了对实际人际互动情境的操纵,单纯采用人际选择反应作为测量自我确认的指标,因而难以形成具有整合性的理论模型。今后的研究有必要在编制合适的测量工具的基础上,将整体自尊与特殊自尊作为两个独立的变量置于整合性实验范式下开展研究,同时采用对人际评价信息的认知判断和对评价者的交往选择的双维指标,以全面揭示整体自尊与特殊自尊对自我确认过程的相对作用及其心理机制。     

农村选民选举行为的结构特征

以云南省两个县八个自然村的 2 62名选民为被试 ,采用心理测量原理与技术探讨了农村选民选举行为的结构特征。结果表明 ,政见取向由“政策效应”、“民生意识”、“村民权益”和“监督机制”4个因素构成 ,非政见取向由“候选人身份”、“候选人德能”、“选民社会关系”、“候选人背景”、“选民自我利益”、“选民自我权利”和“政党意见”7个因素构成。经检验 ,由此构成的农村选举行为问卷具有较高的内部一致性 ,问卷项目具有较高的区分度。文章讨论了农村选民选举行为的结构特征及其意义。     

我国市场经济"信用"动力机制分析及其体系建构

现代社会生活的生产实践表明,分工是交换的前提,交换是分工的实现,这就是现代社会活动的全部内容和过程。在此事实基础上构建的市场经济体制,其管理理念内含着丰富的伦理意蕴[1]。本文首先分析阐述了市场经济信用体系的建立是市场经济体制内在规律的必然要求,揭示了“信用”是承诺者之间能量均衡与博弈的结果,既具有丰富的道德理性又具有明显的功利要求。文章进而通过对信用体系维护的动力因素及其与市场主体行为的相关性进行比较研究后指出:政府在参与市场经济活动中要坚持“有所为,有所不为”,应把政府置于经济利益之外,使之具有超脱于市场各成员的地位;同时,信用体系的创立和维护并不必然由政府主导,而是市场经济环境中公共合意选择的必然结果。
