学习不良儿童家庭资源的元分析

对过去20年关于学习不良儿童家庭资源的研究结果进行的元分析显示,儿童各种家庭资源的效应值变异程度不大。总体来说,学习不良儿童和一般儿童的家庭资源差异显著。一般儿童的父母文化程度和教养方式优于学习不良儿童的父母文化程度和教养方式。但是,两类儿童的父母期望没有显著差异。     

蛋白质组学与神经科学:从蛋白质到网络

多蛋白质信号复合物在所有细胞中都很重要,它们在脑内信息处理也有着重要作用。质谱、双向凝胶电泳、蛋白亲和技术、高通量的免疫组化方法和蛋白质组信息学都蛋白质组学研究的主要手段。应用蛋白质组学方法可以研究多蛋白信号复合的功能,多样性与组成的动态变化。因此,蛋白质组学发展使得人们从单个蛋白质的研究上升到对蛋白质网络的研究。蛋白质组学研究将为神经与精神疾病的诊断技术与治疗手段提供一条新的道路。     

Relationship between COVID-19-related stress and social inhibition among university students in China: The mediating role of psychological richness

Throughout the COVID-19 pandemic, the mental health issues of university students received increasing attention. However, little is known about the effect of COVID-19-related stress on social inhibition among Chinese university students and its psychological mechanism in the context of the COVID-19 pandemic. This study aimed to explore the relationship between COVID-19-related stress and social inhibition as well as the mediating role of psychological richness. In late 2022, 1250 Chinese university students were recruited for participation in an online survey. Modified SARS-Stress Scale, Social Inhibition Questionnaire, and Psychologically Rich Life Questionnaire were used to assess participants' COVID-19-related stress, social inhibition, and psychological richness. The Results indicate that COVID-19-related stress positively predicts social inhibition and negatively predicts psychological richness. Meanwhile, Psychological richness negatively predicts social inhibition. Mediation analysis shows that the relationship between COVID-19-related stress and social inhibition was partially mediated by psychological richness. The results indicate the significant predictive value of psychological richness when studying mental health issues.     

The effect of university ranking on learning satisfaction: Social identities and self‐identity as the suppressor and mediators

The popularization of higher education has developed into a worldwide trend of ranking universities. In light of the lack of research from the student perspective and the non‐individualism of East Asian society, the goal of the present study was to integrate social identity theory and characteristics of Chinese achievement goals in order to determine the relationships between university rankings and students’ university identity, major identity, self‐identity, and learning satisfaction (LS). The participants included 1052 undergraduates (49.4% male, 50.6% female) from 13 universities in Taiwan. A questionnaire was conducted. The results of hierarchical regression analyses show that university ranking positively correlates with students’ university identity, major identity, and self‐identity but negatively correlates with LS due to the effect of university identity acting as a suppressor. The results of structural equation modelling show that: (1) students’ major identity and self‐identity completely mediate the effect of university identity on LS; and (2) university ranking has a significantly negative effect on LS after adding multiple identities as the suppressor and mediators. Furthermore, as students progress further into their studies, both their university identity and major identity gradually decline, while their self‐identity remains constant. Theoretical and practical implications for higher education are also discussed.

More Eagerness,More Suffering from Search Bias: Accuracy Incentives and Need for Cognition Exacerbate the Detrimental Effects of Excessive Searching in Finding Romantic Partners Online

The systematic use of Web search tools to browse and evaluate recommendations is widespread. Such tools may be crucial for users to truly benefit from the enormous selection of options available online. However, a recent study demonstrated that a greater number of search options triggered excessive searching and led to inferior decisions (i.e., the more‐means‐worse effect; Wu & Chiou, 2009 ). Given that individuals who are motivated to make accurate choices (the accuracy incentive) tend to engage in broader and more exhaustive searches, Experiment 1 examined how the accuracy incentive influenced the search process. The findings indicated that the accuracy incentive led to excessive searching and poorer choices. Moreover, the search ratio, an indicator of excessive searching, mediated the negative effect of the accuracy incentive on choice quality. Experiment 2 investigated the role of the need for cognition (NFC) in the more‐means‐worse effect. High‐NFC participants demonstrated an increased tendency toward excessive searching and exhibited poorer selectivity than did low‐NFC participants. The current research indicated that the accuracy incentive of online searchers may serve as a determinant of excessive searching and that online searchers characterized by high NFC may be more vulnerable to the negative effects of excessive searching.

Creating Nostalgic Advertising Based on the Reminiscence Bump: Diachronic Relevance and Purchase Intent

Nostalgic advertising uses images relevant to past periods in individuals' lives to market products. The current study examines the reminiscence bump in a new context: reactions to nostalgic advertising. We examine diachronic relevance and its influence on purchase intent using a 3 (time frame: bump advertisements, non‐bump past advertisements, present‐focused advertisements) × 2 (age group: Generation X, late‐stage baby boomers) between‐subject design. Results show that advertisements for a fictional camera brand (i.e., Optimax) that focus on a bump year (i.e., 15–24 years) have more diachronic relevance than advertisements from either a non‐bump past year or present‐focused advertisements. In addition, advertisements focused on bump years elicit greater intent to purchase the advertised product than non‐bump past and present‐focused advertisements. Analyses show that intent to purchase the product is fully mediated by diachronic relevance of the bump‐year advertisement. These effects hold across both age groups.Copyright © 2016 John Wiley & Sons, Ltd.     

Reducing the effect of stereotype threat: the role of coaction contexts and regulatory fit

Two experiments examined the effects of competition and cooperation contexts, as well as regulatory fit, on reducing the negative influence of stereotype threat. Experiment 1 demonstrated that in high stereotype threat conditions, participants in the cooperation context scored significantly higher on a math test than those in the competition context, while participants in low stereotype threat conditions did not differ in both contexts. Experiment 2 found that under stereotype threat, participants with induced prevention focus scored significantly higher on a math test in the cooperation context than those in the competition context or control group. At the same time, participants with induced promotion foci did not differ between the contexts. Thus, while the cooperation context may counteract the effect of stereotype threat, inducing a promotion focus may create a regulatory fit in the competition context that could also remove the effect of stereotype threat.
