Understanding the link between theory of mind and loneliness among primary school students: A cross-lagged panel model analysis.

This study aimed to investigate the longitudinal association between theory of mind (ToM) and loneliness as well as the potential moderating effects of parenting style on this association. A total of 689 Chinese third-grade students (341 girls and 348 boys; Mage = 9.23 years, SD = 0.66) were recruited from eight primary schools and were followed from Grade 3 to Grade 5. These students reported their primary caregivers' parenting style in third grade and completed the same ToM task and loneliness questionnaire at each time point from Grade 3 to Grade 5. The study's results indicated a bidirectional relationship between ToM and loneliness, implying that children with less developed ToM abilities tend to feel lonelier and, conversely, that higher levels of loneliness are associated with lower ToM skills. Moreover, the study demonstrated that parenting style influenced the association between ToM and loneliness. Specifically, the impact of ToM at Grade 3 on reducing loneliness at Grade 4 was greater among children who experienced high levels of rejection from their caregivers compared with those with low levels of rejection. In addition, this study found that loneliness at Grade 3 had a greater influence on ToM at Grade 5 for children experiencing low levels of emotional warmth from their caregivers than for those who experienced high levels of emotional warmth. These findings highlight the significance of ToM as both a precursor and consequence of children's loneliness and emphasize the variation in these longitudinal relationships based on the parenting styles of primary caregivers.

[Experimental Study on the Characteristic Changes of the Immunological Microenvironment at the Maternal-Fetal Interface in IVF-ET Pregnancy].

Objective: To investigate the characteristic functional changes of the decidual natural killer (NK) cells and γδ T cells, two immunocytes in the decidua, at the maternal-fetal interface in in vitro fertilization-embryo transfer (IVF-ET) pregnancy. Methods: Decidual samples were collected from 12 women of natural pregnancy (NP) and 32 women of IVF-ET pregnancy, who were enrolled in the NP group and the IVF-ET group, respectively. Then part of the decidual samples were paraffin-embedded for HE staining and immunofluorescence staining, while the rest of the samples were digested and Percoll was used for isolating decidual immunocytes (DICs) by gradient centrifugation. Flow cytometry was used to determine the cell counts of decidual NK cells and γδ T cells and the expression levels of their surface activation markers, CD69 and NKG2D in the NP and the IVF-ET groups. In addition, the expression levels of IFN-γ, TNF-α, IL-17A, and IL-10, the intracellular cytokines, and granzyme B, perforin, and granulysin, the cytolytic granules, were measured. The characteristic changes in the relevant immunological indicators were compared and analyzed. Results: HE staining of the tissue specimens showed that the typical structure of decidua was observed, and that lymphocytes were enriched in the decidua. Immunofluorescence staining showed that the percentage of decidual NK (dNK) cells in nucleated cells of the IVF-ET group was significantly lower than that of the NP group ( P<0.05). Flow cytometry analysis of DICs showed that, compared with those of the NP group, the percentage of dNK cells of the IVF-ET group was decreased ( P<0.05) and the expression levels of IL-10 and perforin were significantly decreased in the IVF-ET group ( P<0.05). However, there was no significant difference in the decidual γδ T (dγδT) cell count between the two groups. The expression of IL-10, IL-17A, and perforin was downregulated in the IVF-ET group ( P<0.05). There was no significant difference in the expression of IFN-γ, TNF-α, granzyme B, and granulysin, the cellular function indicators ( P>0.05). Conclusion: The dNK cell count and the secretion of some intracellular cytokines of dNK and dγδT cells of women of IVF-ET pregnancy decreased to some degree, which suggests that certain changes may have taken place in the immunological microenvironment at the maternal-fetal interface. The specific effect of these changes on pregnancy outcomes needs further investigation.

The casual effect of relational mobility on integration of social networks: An agent-based modeling approach.

Despite converging evidence for the importance of relational mobility on shaping people's social experiences, previous work suggested mixed findings for its influence on the structure of sociocentric networks, which lays the basis for the development of all types of social relationships. Additionally, as it is timely and economically intractable to administer such longitudinal experiments in real-life settings, most previous work mainly relied on cross-sectional correlation analyses and provided limited causal evidence. The current research used an agent-based modeling approach to examine whether higher relational mobility (i.e., the number of opportunities to meet new people) would promote integration among social networks over time. Using parameters derived from survey data, we simulated how the integration of sociocentric social networks evolves under different levels of relational mobility. Based on the data of three network structural indicators, including modularity, global efficiency, and standard deviation of nodal betweenness, we obtained causal evidence supporting that higher relational mobility promotes greater network integration. These findings highlight the power of socioecological demands on our social experiences.

Gene expression associated with individual variability in intrinsic functional connectivity.

It has been revealed that intersubject variability (ISV) in intrinsic functional connectivity (FC) is associated with a wide variety of cognitive and behavioral performances. However, the underlying organizational principle of ISV in FC and its related gene transcriptional profiles remain unclear. Using resting-state fMRI data from the Human Connectome Project (299 adult participants) and microarray gene expression data from the Allen Human Brain Atlas, we conducted a transcription-neuroimaging association study to investigate the spatial configurations of ISV in intrinsic FC and their associations with spatial gene transcriptional profiles. We found that the multimodal association cortices showed the greatest ISV in FC, while the unimodal cortices and subcortical areas showed the least ISV. Importantly, partial least squares regression analysis revealed that the transcriptional profiles of genes associated with human accelerated regions (HARs) could explain 31.29% of the variation in the spatial distribution of ISV in FC. The top-related genes in the transcriptional profiles were enriched for the development of the central nervous system, neurogenesis and the cellular components of synapse. Moreover, we observed that the effect of gene expression profile on the heterogeneous distribution of ISV in FC was significantly mediated by the cerebral blood flow configuration. These findings highlighted the spatial arrangement of ISV in FC and their coupling with variations in transcriptional profiles and cerebral blood flow supply.

Fate control and ingroup bias in donation for the fight with the coronavirus pandemic: The mediating role of risk perception of COVID-19.

Ingroup bias could be a significant hindrance in a context where intergroup collaboration is crucial, which makes it essential to investigate ingroup bias during pandemics. This research investigated the influence of individuals' belief in fate control on ingroup bias in helping with COVID-19, and the mediating role of risk perception of COVID-19. To test our hypothesis, we analyzed the data from a community sample (n = 318) collected at the initial stage of the COVID-19 outbreak in China. We found that fate control was positively associated with ingroup bias in donation to the patients with COVID-19 and the frontline healthcare professionals. Moreover, the mediating role of risk perception of COVID-19 was significant. A higher level of fate control was associated with higher risk perception of COVID-19, which was, in turn, related to stronger ingroup bias in donation across individuals. These findings highlight the substantial role of general worldview in shaping individuals' responses to pandemics.

Online/offline self-disclosure to offline friends and relational outcomes in a diary study: The moderating role of self-esteem and relational closeness.

Previous work suggests that the experiences of online and offline self-disclosure are heterogeneous among individuals. Yet little work has been done to identify the moderating role of individual characteristics and pre-existing relationship characteristics on the diverse relational outcomes. The present study using a 7-day diary design examined whether individuals' self-esteem level and relational closeness would moderate the relationships between online and offline self-disclosure to offline friends and two relational outcomes, that is, relationship satisfaction and trust in friendships. The analyses on 686 diary responses from 98 participants revealed that offline self-disclosure generally predicted greater relationship satisfaction and trust in friendships, whereas the role of online self-disclosure was not statistically significant. More importantly, self-esteem moderated the pattern associated with offline self-disclosure but not that with online self-disclosure. Specifically, offline self-disclosure predicted greater benefits to people with lower self-esteem relative to people with higher self-esteem. Moreover, pre-existing relational closeness moderated the relationship between offline self-disclosure and trust in friendships such that casual friendships benefited more from offline self-disclosure than close friendships did. The present study highlights the importance of personal characteristics and relationship characteristics in understanding the heterogeneous relational influence of different communication modes.

Cultural group perception enhances sense of agency in a multicultural society.

Group, which involves collective actions for achieving shared goals, can be conceptually understood as an important source of agency and control. The current research investigated whether group identity salience can enhance sense of agency within the individual. Specifically, we examined whether an activated cultural group identity, through presenting different types of cultural photographs in a predictable way, would facilitate people's sense of agency by using an implicit method, namely, intentional binding effect paradigm. Experiment 1a found that an activated cultural group identity enhanced the sense of agency. Next, Experiment 1b replicated the findings by recruiting a different ethnic group in the same society. Experiment 2 explored what may affect the intensity of induced sense of agency and found that perceived representativeness of the presented cultural stimuli was positively correlated with the intensity of induced sense of agency. Finally, Experiment 3 explored whether ethnic minority and majority groups would demonstrate different intensity of agency when their cultural identity was activated. The results showed that the sense of agency induced by the mainstream cultural stimuli was greater than that induced by the foreign cultural photographs. These patterns were not different between the two ethnic groups. Taken together, these findings reflected the dynamic nature of cultural identity construction in a multicultural society.

Can job autonomy attenuate the effect of depression on employees' well-being? It may depend on culture.

BACKGROUND: Depression is one of the leading causes of work disability. Thus, it is important to explore possible ways to reduce its impact on employees. AIMS: The current research examined whether promoting job autonomy would attenuate the detrimental effect of depression on employees' well-being. METHODS: Study 1 included the data from 5974 full-time employees from China. Full-time employees living in India, a collectivistic culture, and the United States, an individualistic culture, were recruited online in Study 2. RESULTS: Study 1 revealed that job autonomy moderated the influence of depression on job strain and perceived control mediated this interaction effect. Specifically, job autonomy weakened the detrimental effect of depression on job strain via weakening the association between depression and perceived control. The data from the 258 full-time employees in Study 2 replicated the findings and found that job autonomy had a stronger attenuating effect on the influence of depression in India than it had in the United States. CONCLUSIONS: Job autonomy was found to be an effective way to reduce the negative impact of depression on employees' well-being, a finding that should be considered when organizations develop their work policies.

Intrinsic overlapping modular organization of human brain functional networks revealed by a multiobjective evolutionary algorithm.

A wealth of research on resting-state functional MRI (R-fMRI) data has revealed modularity as a fundamental characteristic of the human brain functional network. The modular structure has recently been suggested to be overlapping, meaning that a brain region may engage in multiple modules. However, not only the overlapping modular structure remains inconclusive, the topological features and functional roles of overlapping regions are also poorly understood. To address these issues, the present work utilized the maximal-clique based multiobjective evolutionary algorithm to explore the overlapping modular structure of the R-fMRI data obtained from 57 young healthy adults. Without prior knowledge, brain regions were optimally grouped into eight modules with wide overlap. Based on the topological features captured by graph theory analyses, overlapping regions were classified into an integrated club and a dominant minority club through clustering. Functional flexibility analysis found that overlapping regions in both clubs were significantly more flexible than non-overlapping ones. Lesion simulations revealed that targeted attack at overlapping regions were more damaging than random failure or even targeted attack at hub regions. In particular, overlapping regions in the dominant minority club were more flexible and more crucial for information communication than the others were. Together, our findings demonstrated the highly organized overlapping modular architecture and revealed the importance as well as complexity of overlapping regions from both topological and functional aspects, which provides important implications for their roles in executing multiple tasks and maintaining information communication.

Seeing the big picture: Broadening attention relieves sadness and depressed mood.

We examined whether the broadened attentional scope would affect people's sad or depressed mood with two experiments, enlightened by the meaning of "seeing the big picture" and the broaden-and-build model. Experiment 1 (n = 164) is a laboratory-based experiment, in which we manipulated the attentional scope by showing participants zoomed-out or zoomed-in scenes. In Experiment 2 (n = 44), we studied how depressed mood and positive and negative emotions were affected when participants watched distant versus proximal scenes for eight weeks in real life. Healthy participants in Experiment 1, who were induced to feel sad, could return to the baseline mood after having the broadened attention task but not after having the narrowed attention task, which indicated that immediate attention broadening manipulation could function as antidotes for the lingering effects of induced negative emotions. Participants with depressed mood in Experiment 2 showed reduced depressed mood, increased positive affect, and decreased negative affect after receiving attention broadening training compared to those receiving attention narrowing training. Our findings suggest a robust role of broadened attentional scope in relieving negative emotions and even mildly depressed mood in the long run.

Predictors of the gender gap in life expectancy across 54 nations.

We studied the gender gap in life expectancy (GGLE), which currently favours women on average by 5 years. Individual data from 54 societies were extracted from the 1999-2004 wave of the World Values Survey. The GGLE was not predicted by the socio-economic factors of gross domestic product (GDP) or Gini coefficient, but was increased by national level of alcohol consumption, and decreased by gender differences in national levels of life satisfaction. Different national-level phenomena appear to be responsible for male and female contributions to the GGLE. National levels of male longevity were responsive to GDP, Gini coefficient, social engagement, tobacco use and life satisfaction, whereas female longevity rates were responsive only to GDP and alcohol consumption, underscoring the greater sensitivity of male longevity to contextual features of the nations where they live.

Relationships between parental involvement in homework and learning outcomes among elementary school students: The moderating role of societal collectivism-individualism.

BACKGROUND: Parents are often involved in their child's homework with the goal of improving their child's academic achievement. However, mixed findings were observed for the role of parental involvement in homework in shaping students' learning outcomes. AIMS: The present study examined whether and how the effect of parental involvement in homework on students' performance in science and math varies across sociocultural contexts by considering the degrees of societal collectivism-individualism. METHODS: The present study used a large-scale dataset, consisting of participants from 43 countries/regions, to test whether societal collectivism-individualism would moderate the relationship between three types of parental involvement (asking, helping and checking) in homework and elementary school students' academic performance in math and science. RESULTS: The multi-level analyses revealed diverse effects of different parental involvement behaviours for homework. Helping and checking behaviours were generally negatively associated with elementary school students' academic achievement, but asking behaviours were positively associated with their academic achievement. Importantly, the positive effect of asking behaviours was stronger, while the negative effect of helping behaviours was weaker in collectivistic societies than in individualistic societies. CONCLUSIONS: The present study highlights the importance of considering the multifaceted nature of parental homework involvement and the sociocultural contexts that vary in collectivism-individualism when evaluating the role of parents in elementary school students' learning in math and science.

Egoistic value is positively associated with pro-environmental attitude and behaviour when the environmental problems are psychologically close.

Egoistic value is conceptualized as anti-environmental in many environmental value theories, yet contradictory evidence exists for its relation with pro-environmental attitude and behaviour. To provide insights into these inconsistent findings, this research examined the moderating role of the psychological distance of environmental problems on their relationship. Across one cross-sectional survey study (1008 community participants from the United States) and one World Values Survey study (66,704 nationally representative participants from 46 countries/regions), results converged in showing that psychological distance of environmental problems (i.e. climate change and local pollution) moderated the relationship between egoistic value and pro-environmental attitude and behaviour. Their association became more positive as that psychological distance got closer. Different patterns were observed for altruistic and biospheric values. These findings highlight the potential pro-environmental utility of egoistic value and the importance of paying attention to contexts when theorizing its relation with pro-environmental attitude and behaviour.

Dual-earner couples' sharing of work-related experiences: Effects on relational and personal well-being.

Personal growth and self-expressive goals have become increasingly important in modern marriages. In dual-earner couples, sharing work-related experiences with the partner can be particularly important in promoting mutual support for each other's personal growth. The current study examined dual-earner couples' sharing of work-related experiences and how it influenced both partners' relationship satisfaction and personal well-being. A total of 102 heterosexual dual-earner couples were recruited from communities in Hong Kong. They completed a pretest survey, a 14-day daily diary study, and a follow-up survey 1 year later. The Actor-Partner Interdependence Model was adopted to analyze the dyadic effects of sharing positive and negative work-related experiences on relationship satisfaction and personal well-being on the same day and 1 year later. In general, the sharing of both positive and negative work-related experiences had beneficial effects on the outcomes. Specifically, wives' sharing had more immediate effects on both partners' relational and personal well-being, whereas husbands' sharing had more long-term effects on the partner's personal well-being. The findings highlight the importance of work-related sharing in dual-earner couples. Practical implications are discussed.

The mindsets × societal norm effect across 78 cultures: Growth mindsets are linked to performance weakly and well-being negatively in societies with fixed-mindset norms.

BACKGROUND/AIMS: Recent research on mindsets has shifted from understanding its homogenous role on performance to understanding how classroom environments explain its heterogeneous effects (i.e., Mindsets × Context hypothesis). Does the macro context (e.g., societal level of student mindsets) also help explain its heterogeneous effects? And does this interaction effect also apply to understanding students' well-being? To address these questions, we examined whether and how the role of students' mindsets in performance (math, science, reading) and well-being (meaning in life, positive affect, life satisfaction) depends on the societal-mindset norms (i.e., Mindsets × Societal Norm effect). SAMPLE/METHODS: We analysed a global data set (n = 612,004 adolescents in 78 societies) using multilevel analysis. The societal norm of student mindsets was the average score derived from students within each society. RESULTS: Growth mindsets positively and weakly predicted all performance outcomes (rs = .192, .210, .224), but the associations were significantly stronger in societies with growth-mindset norms. In contrast, the associations between growth mindsets and psychological well-being were very weak and inconsistent (rs = -.066, .003, .008). Importantly, the association was negative in societies with fixed-mindset norms but positive in societies with growth-mindset norms. CONCLUSIONS: These findings challenge the idea that growth mindsets have ubiquitous positive effects in all societies. Growth mindsets might be ineffective or even detrimental in societies with fixed-mindset norms because such societal norms could suppress the potential of students with growth mindsets and undermines their well-being. Researchers should take societal norms into consideration in their efforts to understand and foster students' growth.

Insomnia is associated with conspiracy mentality, psychological distress, and psychological well-being.

RATIONALE: Conspiracy theories are frequently encountered as they exist across all domains of life, from interpersonal issues in the workplace to global events. Research has primarily focused on uncovering the antecedents of conspiracy beliefs; meanwhile, little research has examined the impacts of possessing a conspiracy mentality. OBJECTIVE: In the current research, we examined the relationships of conspiracy mentality with perceived control, insomnia, psychological well-being (i.e., positive emotions, engagement, relationships, meaning, and achievement), and psychological distress (i.e., anxiety and depression). METHODS: Participants (N = 388) reported their conspiracy mentality at Time 1 and then completed measures assessing perceived control, insomnia, psychological well-being, and psychological distress 1 month later at Time 2. We conducted regression analyses, structural equation modeling, and bootstrapping analyses to test our predictions that conspiracy mentality predicts insomnia through thwarted perceived control and that this relationship carries direct implications for psychological well-being and distress. RESULTS: As predicted, regression analyses showed that conspiracy mentality is negatively associated with perceived control and indicators of psychological well-being, and positively associated with insomnia and indicators of psychological distress 1 month later. The results of structural equation modeling and bootstrapping analyses provided empirical support to our theoretical model that perceived control and insomnia serially mediate the relationship between conspiracy mentality and both psychological well-being and psychological distress. CONCLUSIONS: These findings offer important contributions to the literature on conspiracy beliefs. Practically, they offer potential routes of intervention to weaken insomnia and psychological distress and enhance psychological well-being.

Individual uniqueness in trust profiles and well-being: Understanding the role of cultural tightness-looseness from a representation similarity perspective.

This paper provides a unique perspective for understanding cultural differences: representation similarity-a computational technique that uses pairwise comparisons of units to reveal their representation in higher-order space. By combining individual-level measures of trust across domains and well-being from 13,823 participants across 15 nations with a measure of society-level tightness-looseness, we found that any two countries with more similar tightness-looseness tendencies exhibit higher degrees of representation similarity in national interpersonal trust profiles. Although each individual's trust profile is generally similar to their nation's trust profile, the greater similarity between an individual's and their society's trust profile predicted a higher level of individual life satisfaction only in loose cultures but not in tight cultures. Using the framework of representation similarity to explore cross-cultural differences from a multidimensional, multi-national perspective provide a comprehensive picture of how culture is related to the human activities.

Metal-organic framework ZIF-8 nanocrystals as pseudostationary phase for capillary electrokinetic chromatography.

The outstanding properties such as large surface area, diverse structure, and accessible tunnels and cages make metal organic frameworks (MOFs) attractive as novel separation media in separation sciences. However, the utilization of MOFs in EKC has not been reported before. Here we show the exploration of zeolitic imidazolate framework-8 (ZIF-8), one of famous MOFs, as the pseudostationary phase (PSP) in EKC. ZIF-8 nanocrystals were used as the PSP through dispersing in the running buffer (20 mM phosphate solution containing a 1% v/v methanol (pH 9.2)) to enhance the separation of the phenolic isomers (p-benzenediol, m-benzenediol, o-benzenediol, m-nitrophenol, p-nitrophenol, and o-nitrophenol). ZIF-8 nanocrystals in the running buffer were negatively charged, and interacted with the phenolic hydroxyl groups of the analytes, and thus greatly improved the separation of the phenolic isomers. Inclusion of 200 mg L-(1) ZIF-8 in the running buffer as the background electrolyte gave a baseline separation of the phenolic isomers within 4 min. The relative standard deviations for five replicate separations of the phenolic isomers were 0.2-1.1% for migration time and 4.5-9.7% for peak area. The limits of detection varied from 0.44 to 2.0 mg L-(1) . The results show that nanosized MOFs are promising for application in EKC.

When and how to share? The role of inspiration.

Sharing what we know with others has an important role in facilitating people's social learning and communication across settings. To advance the understanding of when and how people share, the present study examined the role of inspiration, an emotion that contains strong motivational elements, on people's sharing tendencies in three studies. Study 1 showed a positive association between the inspiring level of a given message and its likelihood of being shared. Study 2 replicated the finding with carefully controlling for the effect of positivity of a given message. Study 3 further provided evidence that inspiration shaped how people share. The results showed that participants shared inspiring messages in a more innovative way than when they shared less inspiring messages. The present research has implications for how to promote the sharing process in different settings through the role of inspiration.

Functional connectivity dynamics as a function of the fluctuation of tension during film watching.

To advance the understanding of the dynamic relationship between brain activities and emotional experiences, we examined the neural patterns of tension, a unique emotion that highly depends on how an event unfolds. Specifically, the present study explored the temporal relationship between functional connectivity patterns within and between different brain functional modules and the fluctuation in tension during film watching. Due to the highly contextualized and time-varying nature of tension, we expected that multiple neural networks would be involved in the dynamic tension experience. Using the neuroimaging data of 546 participants, we conducted a dynamic brain analysis to identify the intra- and inter-module functional connectivity patterns that are significantly correlated with the fluctuation of tension over time. The results showed that the inter-module connectivity of cingulo-opercular network, fronto-parietal network, and default mode network is involved in the dynamic experience of tension. These findings demonstrate a close relationship between brain functional connectivity patterns and emotional dynamics, which supports the importance of functional connectivity dynamics in understanding our cognitive and emotional processes.
