According to the CAD model of emotional responses to immorality, if an event violates the moral foundations of justice and harm, people will feel angry. However, the model is silent on whether the strength of association between anger and perceived injustice/harm is context‐dependent. Using a contextual priming paradigm, the current research shows that in China, the association between anger and perceived injustice/harm is stronger when work (vs family) and modern (vs traditional) contexts are primed. Specifically, we primed modernity versus traditionality (Experiment 1) and work experiences (Experiment 2) and measured the strength of association between justice/harm concerns and anger. The results show that: (i) the linkage between justice/harm concern and anger was stronger in the modernity priming condition than in the tradition priming or control conditions; and (ii) the linkage between justice/harm concern and anger was stronger in the work experience priming condition than in the control condition. In short, priming modern and work contexts strengthens the association between justice/harm concerns and anger, suggesting the strength of the morality–emotion link is context‐dependent. 相似文献

People are increasingly worried about untruthfulness in news reporting. We distinguish between two types of untruthfulness: apparent untruthfulness (containing false information) and consequential untruthfulness (giving readers a wrong impression of the truth). Consequential untruthfulness can be caused by both the presence of false information and cherry-picking (reporting only parts of the truth). Despite this, we find that people's perception of untruthfulness depends largely on apparent untruthfulness. Consequently, they treat news that cherry-picks information less negatively (e.g., less likely to criticize it and more likely to share it with others) than they treat news that contains false information, when the former is more consequentially untruthful than the latter. We dub this phenomenon as cherry-picking tolerance. We also find that prompting people to think about the consequence of the news report (i.e., the impressions people form after they read the news reports) will mitigate the cherry-picking tolerance. This research draws attention to the widespread practice of cherry-picking in news reporting and calls for a new look at what constitutes fake news. 相似文献

Prevention of depressive disorders is one of the most important challenges for health care in coming decades. Depressive disorders in all age groups have a high disease burden and are associated with huge economic costs, and current treatments are only capable of taking away one‐third of the (nonfatal) disease burden of depression under optimal conditions. Prevention may be one alternative strategy that may help in further reducing the disease burden of depression. Because of the worldwide increase in the number of older adults, the number of depressed older adults will also increase considerably in the next few decades, making prevention of depression an important priority for research. Identifying the high‐risk target groups for preventive interventions is complicated because most risk indicators have a low specificity, indicating that most people from these groups will not develop the disorder despite increased risk levels. We describe one promising method to identify the best target groups, based on the principle that the high‐risk group should be as small as possible, should be responsible for as many new cases of depression as possible, and that intervention be as effective as possible. The number of trials examining the possibility to prevent the onset of depressive disorders in those who do not (yet) meet diagnostic criteria for depression is increasing rapidly. A recent meta‐analysis identified more than 30 randomized trials and these studies showed that the incidence of depressive disorders was 21% lower in the prevention groups compared with the control groups who did not receive the preventive intervention. Most of these trials are aimed at adolescents and younger adults. Only six trials were specifically aimed at older adults. The development of evidence‐based preventive interventions for major depression and other mental disorders should be an important scientific and public health objective for the 21st century. 相似文献

We examined the causes of a growing achievement gap associated with socioeconomic status (SES) in Korea and Japan, testing whether parenting self-efficacy (PSE) and parental involvement (PI) mediated or moderated the association of SES to children’s school-related competence (SRC). Three hundred and seventy-two Korean and 309 Japanese mothers of first- and second-grade children completed a parenting survey. Japanese mothers’ education and PSE were directly associated with SRC. PSE moderated the association of education to SRC, with higher PSE of college-educated mothers positively associated with SRC. In the Korean sample, household income was associated with SRC directly as well as indirectly through PSE. 相似文献

Families’ academic socialization mediates how socioeconomic status (SES) affects children’s achievement. However, little is known about whether cultural values and family cohesion could buffer negative effects of low SES. We examined parental academic socialization and children’s achievement in 220 low- and middle-SES Chinese immigrant families with four-year-olds. Low-SES parents showed less stressful family environments and stronger beliefs about parental responsibility for education. However, middle-SES parents provided more reading engagement and enrichment activities. Reading engagement and SES were significantly associated with children’s academic performance. These findings demonstrate low-SES families’ strengths but suggest the need to provide more support for such families. 相似文献

Is religion more of an integrative or a divisive force in contemporary societies? We use multilevel analyses of World Values Survey data from 77,409 individuals in 69 countries to examine how both the percent of the population that is religious and the religious heterogeneity of a country are related to generalized social trust, the willingness of individuals to trust “most people.” When we first examine the main effects of the percent religious and religious heterogeneity we find no evidence that either variable is related to trust in the ways predicted by major theories. However, the combination of these two variables has a huge negative relationship with trust. Countries that are both highly religious and religiously heterogeneous (diverse) have, on average, levels of trust that are only half the average levels of countries with other combinations of these two variables. The results have important implications for understanding the role of religion in modern societies. 相似文献

The author examined what and how factors affect the employment status of Taiwanese college students with disabilities in the 1st year after graduation. The results demonstrated that (a) perceived acceptance by society and the employment market (ASEM) was the major factor affecting the employment status of individuals with disabilities (IWDs); (b) perceived ASEM influenced IWDs' psychological states, attitudes, and life‐planning styles, as well as their attitudes and strategies in job searching; and (c) the effect of IWDs' acceptance expectations on their employment development can be explained by the self‐fulfilling prophecy. 相似文献

Several investigations have found that prisoners are more likely than nonprisoners to engage in risky behavior, which may contribute to their propensity to commit criminal offenses. However, this research has been limited by an almost exclusive focus on male samples. Given the established link between risk taking and gender, it is thus unclear how findings on the risk‐taking propensities of prisoners also hold in women. The present study uses both a self‐report questionnaire (Domain‐Specific Risk Taking scale, DOSPERT) and a behavioral task (Balloon Analogue Risk Task, BART) to investigate risk‐taking tendencies in a Chinese prisoner group and a nonprisoner control group with balanced gender proportions. Across both genders, prisoners both indicated a higher risk‐taking tendency on the DOSPERT and showed more risk‐taking behavior on the BART than did nonprisoners. Importantly, the differences were considerably more pronounced in women than in men. Relative to nonprisoners, gender differences in risk taking were substantially smaller, or even reversed, in prisoners. Computational modeling of respondents' behavior in the BART revealed that the prisoners had higher reward sensitivity and lower response consistency than the nonprisoners; these differences were again more pronounced among women. Our results suggest that previous studies based primarily on male prisoners may have underestimated differences in risk taking between prisoners and nonprisoners, and that female prisoners may represent an even more extreme subpopulation than male prisoners.

The nucleation undercoolings of non-magnetic metals like paramagnetic aluminium in high magnetic fields were measured by the differential thermal analysis technique. It was shown that the nucleation undercooling of pure aluminium increased with increasing the magnetic field, while its melting temperature was hardly changed. Based on the model of magnetic dipoles at the interface, it is proposed that the magnetic-field-induced interfacial energy mainly contributes to the increase in undercooling. The change in undercooling in the magnetic field is calculated theoretically, which is in comparison with experimental data. Additionally, the inhibition of atom diffusion in the magnetic field plays a role in the change of undercooling. 相似文献
