Fragility of Happiness Beliefs Across 15 National Groups

The belief that happiness is fragile—that it is fleeting and may easily turn into less favourable states—is common across individuals and cultures. However, not much is known about this belief domain and its structure and correlates. In the present study, we use multigroup confirmatory factor analysis and multilevel modelling to investigate the measurement invariance, cross-level isomorphism, predictive validity, and nomological network of the fragility of happiness scale across 15 nations. The results show that this scale has good statistical properties at both individual and cultural levels, and is associated with relevant psycho-social concepts in expected directions. The importance of the results, limitations, and potential directions for future research are discussed.     

医疗器械软件设计及应用的伦理考量

通过收集2017年~2021年北京某三甲医院开展的14项医疗器械软件的软件说明书、技术要求和注册检验报告等临床试验资料,从医学伦理的角度对产品的功能和技术标准涉及的共性问题进行分析归纳,重点探讨了医疗器械软件的标准参考情况、数据管理和风险控制措施方面的相关问题,提出了医疗器械软件在设计和使用过程中应当考虑适用范围泛化、预警和交互等可能衍生伦理学问题的因素,加强软件风险管理,从而减少因软件缺陷产生的严重不良事件。

     

最后通牒博弈中提议者情绪预测偏差对公平决策的影响:公平感知的作用

为探讨提议者情绪预测偏差对公平决策的影响以及其中介机制,采用了两轮最后通牒博弈提议者实验任务,第一轮测量分配方案被接受和拒绝的情绪预测偏差,第二轮测量提议者的分配方案。研究结果表明:(1)提议者情绪预测偏差影响公平决策;(2)公平感知在提议者情绪预测偏差与公平决策间起部分中介作用。研究认为,提议者对积极结果的情绪预测偏差,会降低其公平感知,进而降低其分配方案公平性; 提议者对消极结果的情绪预测偏差,会提高其公平感知,进而增加其分配方案公平性。     

情绪的确定性评价对信息加工的影响

检验了情绪的效价和确定性评价对个体的信息加工策略选择的影响及其心理机制。结果表明,情绪效价对个体的信息加工方式的影响会受到情绪确定性评价的调节。高确定评价的情绪中,积极情绪的被试更倾向于采用启发式加工,消极情绪的被试更倾向于采用系统式加工。积极情绪中,高确定评价情绪的被试更倾向于采用启发式加工,低确定评价情绪的被试更倾向于采用系统式加工。当个体对自己产生情绪的原因进行合理归因后,情绪效价和确定性评价对个体信息加工方式的影响效应都消失了,说明情绪的效价和确定性评价均以信息的方式对对个体信息加工策略的选择产生影响。     

Acquisition of habitual visual attention and transfer to related tasks

Extensive research has shown that statistical learning affects perception, attention, and action control; however, few studies have directly linked statistical learning with the formation of habits. Evidence that learning can induce a search habit has come from location probability learning, in which people prioritize locations frequently attended to in the past. Here, using an alternating training–testing procedure, we demonstrated that the initial attentional bias arises from short-term intertrial priming, whereas probability learning takes longer to emerge, first reaching significance in covert orienting (measured by reaction times) after about 48 training trials, and in overt orienting (measured by eye movements) after about 96 training trials. We further showed that location probability learning is persistent after training is discontinued, by transferring from a letter search task to a scene search task—emulating another characteristic feature of habits. By identifying the onset of probability learning and investigating its task specificity, this study provides evidence that probability cuing can induce habitual spatial attention.     

语言功能偏侧化及其与利手、功能连接的关系

对大脑语言功能偏侧化的探索起始于早期对脑损伤病人的研究。现代脑影像学研究发现, 语言功能偏侧化涉及额叶、颞叶、扣带回、梭状回和辅助运动区等脑区。语言偏侧化与利手和静息态功能连接之间的关系表现为：右利手的语言优势位于左半球, 而左利手的则分布在左半球、右半球或两个半球; 语言功能偏侧化与利手系数、静息态半球内功能连接之间具有正相关关系, 与半球间功能连接呈负相关, 并且语言功能偏侧化与静息态功能连接之间的关系在左右利手个体之间存在差异。总之, 大脑语言功能偏侧化、利手和静息态功能连接三者之间存在相互影响, 基于脑连接和遗传机制的研究将有望揭示出其底层的神经生理机制。     

童年期创伤对大学生抑郁的影响:早期适应不良图式和负性生活事件的作用

目的:考察早期适应不良图式、负性生活事件在童年期创伤与大学生抑郁间的影响机制。方法:采用童年期创伤问卷、Young图式问卷短版中文修订版、青少年生活事件量表及90项症状自评量表对1423名大学生进行调查,结果表明:(1)童年期创伤既可以直接正向预测大学生抑郁,也可以通过早期适应不良图式中的分离和拒绝、自主性及能力受损两大图式类别间接地正向预测大学生抑郁;(2)负性生活事件调节了早期适应不良图式在童年期创伤与抑郁间的中介作用     

The implicit sociometer effect and the moderating role of relational self‐construal

The present study examined how negative feedback influenced implicit self‐evaluations and how individuals' level of relational self‐construal (RelSC) moderated these relationships. One hundred Chinese university students completed the relational‐interdependent self‐construal scale and were randomly assigned into one of three conditions (social exclusion, personal failure, or control). After receiving the manipulation, participants completed two Brief Implicit Association Tests (BIATs) that measured their implicit self‐liking and self‐competence. The results indicated that people with a highly RelSC typically had higher implicit self‐liking, but they decreased their implicit self‐liking more than those with a low RelSC after experiencing social exclusion. However, RelSC did not influence the effect of personal failure on implicit self‐liking. In addition, RelSC was not associated with implicit self‐competence in any situation.     

When the poor excel: Poverty facilitates procedural learning

Recent research has shown that poverty directly impeded cognitive functions because the poor could be easily distracted by monetary concerns. We argue that this effect may be limited to functions relying on working memory. For functions that rely on proceduralized processes however, monetary concerns elicited by reminding of financial demands would be conducive rather than harmful. Our results supported this hypothesis by showing that participants with lower income reached the learning criterion of the information‐integration categorization task faster than their more affluent counterparts after reminding of financial demands.
