The Effects of Applicant Résumé Contents on Recruiters' Hiring Recommendations: The Mediating Roles of Recruiter Fit Perceptions

The résumé is the most commonly used selection tool for organisations. Past studies have demonstrated that recruiter hiring recommendations can be predicted based on the content of applicant résumés. However, the mechanisms underlying the links between résumé contents and hiring recommendations remain unclear. The present study extends previous research by examining the mediating roles of recruiters' multi‐faceted fit perceptions in a field setting. Data were collected from 216 organisational recruiters who participated in campus recruitment at seven universities in Taiwan. The results showed that applicant work experience and educational background increased recruiter hiring recommendations through recruiter perceived person–job (P–J) fit. In addition, applicant work experience predicted recruiter perceived person–organisation (P–O) fit, which in turn enhanced recruiter hiring recommendations.     

Sense of community improves community participation in Chinese residential communities: The mediating role of sense of community responsibility and prosocial tendencies

Community participation is essential for community development and enhancing quality of life. Several studies have focused on the relationship between sense of community (SOC) and community participation in organizational settings. Guided by the community experiences framework, this study aims to examine how a SOC improves community participation in Chinese residential communities. Moreover, the study aims to assess the mediating role of SOC responsibility (SOC-R) and prosocial tendencies in that relationship. A sample of 433 residents completed questionnaires regarding their SOC, sense of community responsibility, prosocial tendencies, and community participation. Using a linear regression model, we found that a SOC can positively predict the level of community participation. Mediation effect analysis revealed that a SOC-R mediated the relationship between SOC and community participation. In addition, prosocial tendencies mediated the association between the SOC and community participation. Using multiple mediation analysis, we found that SOC-R and prosocial tendencies mediated the link between a SOC and community participation in a sequential manner. The findings of this study complement existing research by uncovering the mechanism underlying the relationship between a SOC and community participation.

Rice-farming areas report more anxiety across two years of the COVID-19 pandemic in China

Cultures responded to the COVID-19 pandemic differently. We investigated cultural differences in mental health during the pandemic. We found regional differences in people's reports of anxiety in China over two years from 2020 to 2021 (N = 1186). People in areas with a history of rice farming reported more anxiety than people in wheat-farming areas. Next, we explored more proximal mechanisms that could help link the distal, historical factor of rice farming to people's modern experience of anxiety. Rice areas scored higher on collectivism and tight social norms than wheat areas, and collectivism, rather than norm tightness, mediated the rice-anxiety relationship. These findings advance our understanding of the distal sources of cultural differences, the proximal mechanisms, and mental health problems during the pandemics.     

Chicks Injected with Antisera to either S-100α or S-100β Protein Develop Amnesia for a Passive Avoidance Task

The cellular expression of S-100β protein is upregulated in Alzheimer's disease and in Down's syndrome, and this protein has been implicated in memory-related processes in laboratory animals. However, the possibility that the α subunit of S-100 is also involved in memory has not yet been examined. In the present study, day-old black Australorp white Leghorn cockerel chicks (Gallus domesticus) received injections of monoclonal antisera to S-100α (1:50) or S-100β (1:500) into each hemisphere immediately after training on a one-trial passive avoidance task. The chicks displayed significantly lower retention levels than control birds that had been injected with antisera to carbonic anhydrase, or with saline (p< .01). S-100α antisera had an amnestic effect when injected between 0 and 20 min after training, with memory deficits occurring from 30 min postlearning, at the point of transition between the A and the B phases of the Gibbs-Ng intermediate memory stage. By contrast, the S-100β antisera needed to be injected either 5 min before or immediately after training and produced amnesia 10 min earlier, at the start of the A phase of the intermediate memory stage. We conclude that the two subunits of the S-100 protein are required at different points in the sequence of events leading to the consolidation of passive avoidance memory.     

3─6岁儿童传递性关系推理的研究

设计三种情境考察被试的推理情况,并试图揭示儿童是怎样进行传递性关系推理的。结果显示：（１）３—６岁儿童具有进行传递性关系推理能力;（２）造成我国３—６岁儿童作传递性关系推理失败的原因有二：一是错误理解比较句式,二是没有记住前提;（３）３—６岁儿童进行传递性关系推理的内部过程不同：小年龄段被试多采用“局部加工模式”,大龄段被试多采用“整体空间加工模式”。     

回避与趋近性负性人格特质对应激心血管反应模式的不同影响

本研究考察了回避与趋近性负性特质对不同强度心理社会应激刺激重复暴露的心血管反应、应激后心血管反应恢复、重复应激心血管反应的影响,并探讨了应激认知评价在其中的作用。167名大学生被试被随机分配到中/高强度应激条件中,连续采集其在基线期、首次应激期、恢复期、重复应激期四个阶段的心血管反应数据。结果发现:(1)无论应激强度如何,回避性负性特质预测首次和重复应激中较低(钝化)的心血管反应和应激后较差的恢复,而趋近性负性特质预测较大的心血管反应和应激后较差的恢复。(2)重复应激个人资源感知在回避性负性特质与重复应激心率反应之间起中介作用。因此,回避性负性特质与持续较低(钝化)的应激心血管反应和应激后较差的恢复相联系,而趋近性负性特质与较大的应激心血管反应和应激后较差的恢复相联系,即两类负性特质均表现出不适应的固化的应激心血管反应模式,这可能构成了两类不同负性特质增加罹患心血管疾病风险的生理机制。     

视觉观点采择中自我中心性偏差的抑制和归因之争

自我中心性偏差是社交失败的重要原因,但其产生机制还存在争议。以往研究存在抑制性选择模型与流利性错误归因两种理论观点:前者认为对自身观点的抑制失败会导致自我中心性偏差;后者则认为错误地选择自身更为流畅的信息会导致自我中心性偏差。为整合上述争论,提出抑制-归因协同作用模型,认为抑制和归因两种加工或可共同导致自我中心性偏差。未来研究应借助精巧的研究范式和特殊被试群体,进一步验证该模型。     

基于心灵知觉理论的AI服务用户接受机制及使用促进策略

许多企业采用人工智能服务应答顾客需求,然而多项研究指出用户并不总是对此感到满意。本研究围绕着用户对AI的心灵知觉的产生和影响,探索了驱动用户对AI服务态度的关键因素及使用促进策略,包括(1)机理分析层面：用户与AI早期接触的线索和体验因素如何使得人们产生了AI“擅长计算却缺乏感受”的心灵知觉？(2)调节作用层面：不同的用户内部状态和AI外部特征怎样调节了这种心灵知觉的形成和激活？(3)促进策略层面：将AI拟动物化和提供技术援助为何能借助心灵知觉使得用户在更广泛的场景中接受来自AI的服务？本研究试图在学理层面构建一个基于心灵知觉理论的新型AI服务接受模型,为从理论上解释用户对AI服务的矛盾态度提供心理学参考;同时试图在实践层面上借助心灵知觉理论提出两种促进用户接受AI服务的路径方法,为企业在服务中提升AI的应用效能提供技术参考。
