Preventive health practices have been crucial to mitigating viral spread during the COVID-19 pandemic. In two studies, we examined whether intellectual humility—openness to one's existing knowledge being inaccurate—related to greater engagement in preventive health practices (social distancing, handwashing, mask-wearing). In Study 1, we found that intellectually humble people were more likely to engage in COVID-19 preventive practices. Additionally, this link was driven by intellectually humble people's tendency to adopt information from data-driven sources (e.g., medical experts) and greater feelings of responsibility over the outcomes of COVID-19. In Study 2, we found support for these relationships over time (2 weeks). Additionally, Study 2 showed that the link between intellectual humility and preventive practices was driven by a greater tendency to adopt data-driven information when encountering it, rather than actively seeking out such information. These findings reveal the promising role of intellectual humility in making well-informed decisions during public health crises. 相似文献

用追踪研究方法,对60名幼儿在高兴、惊讶与害怕情境中的情绪表达规则认知两年的发展进行探讨,并考察情绪情境、性别和人际背景对其发展的影响。结果表明:(1)幼儿的情绪表达规则知识、目标和策略水平均随年龄增长显著提升;(2)幼儿在害怕情境中为自我保护而较多使用掩饰策略,在惊讶情境中较多使用掩饰和夸大策略,在高兴情境中综合运用掩饰、弱化和夸大策略;(3)性别和人际背景均对幼儿情绪表达规则认知发展有显著影响。 相似文献

This paper examines the ethical issues of conflict of interest raised by the burgeoning development of physician involvement in for-profit entrepreneurial activities outside their practice. After documenting the nature and extent of these activities, and their potential for conflicts of interest, the paper assesses the major arguments for and against physicians' referral of patients to facilities they own or in which they invest. The paper concludes that an outright ban on such activity seems ethically warranted. 相似文献

The face-to-face interactions of 43 polydrug-with-cocaine-using mothers and their infants at 3 and 6 months were compared to 17 non-cocaine-but other-drug-using mothers and 21 mothers who used no drugs during their pregnancy. Coders blind to mothers' drug use status scored 3 min of face-to-face interactions for 16 measures of maternal and infant interactive behaviors. A principal component of 7 behaviors formed a measure of maternal attentiveness; a principal component of 5 behaviors formed a measure of mother-infant dyadic organization; and a principal component of 4 behaviors formed a measure of infant readiness to interact. A measure of maternal interruption was computed as the mean standard score of 3 additional interruptive behaviors. At 3 and 6 months, polydrug-with-cocaine-using mothers were less attentive to interactions, and polydrug-with-cocaine-using mothers and their infants engaged in fewer dyadic interactions than either non-cocaine or non-drug-using mothers. Compared to 3 months, polydrug-with-cocaine-using mothers at 6 months were less attentive to interactions and more frequently interrupted interactions by looking away, redirecting the infant, or withdrawing, whereas non-cocaine-using and non-drug- using mothers showed no change or an improvement in attentiveness to interactions and a decrease in interruptions. No differences emerged in the interactive behaviors of the infants of polydrug- with-cocaine-using, non-cocaine-using, or non-drug-using mothers. Cocaine use represents a significant risk for diminished parental attentiveness and responsiveness to infants and for diminished interactiveness in infants. 相似文献

An exploratory study of the values of inner-city postpartum women was conducted. Subjects were largely single, with many on/or going on public assistance. Each subject was given the Rokeach Value Scale and asked to prioritize the terminal values (goals) in terms of herself and the instrumental values (means) in terms of what she would like to teach her child. Rankings were compared to corresponding rankings compiled by a national sample, considered a more traditional era, and by marital status within the postpartum mother sample itself. Economic values were ranked higher by inner-city mothers than by the national sample. The top terminal value was family security and the top instrumental value was responsible. When compared by marital status, the only significant difference was the higher ranking of mature love given by married women. Results suggests that the values of the inner-city single postpartum mother can be conceptualized as a mosaic incorporating values shared with the mainstream and values adapted to the conditions of poverty. 相似文献

A multidisciplinary group of genetic and other professionals discuss a complex case of familial conflict over access to genetic information. One twin wishes to know the results of her deceased mother's tests for BRCA1 mutations; a second twin objects to researchers making this information available. As the case discussion unfolds, the apparent facts of this case are called into question and the lines of ethical certainty become less clear. 相似文献

Propositional and notional attitudes are construed as relations (-in-intension) between individuals and constructions (rather than propositrions etc,). The apparatus of transparent intensional logic (Tichy) is applied to derive two rules that make it possible to export existential quantifiers without conceiving attitudes as relations to expressions (sententialism). 相似文献

Tested a theoretical model on the effects of social role identity, illness intrusion, and competence on psychological well-being among 109 low-income Latinas with arthritis. All six roles studied were rated as highly important identities. Sex-role nontraditionalism was associated with less importance of the homemaker, mother, and grandmother roles. Negative affect increased as a function of intrusions into valued identities. Having important role identities contributed to feelings of competence (i.e., self-esteem and self-efficacy), which in turn, contributed to psychological well-being. Competence also mediated the effects of pain, identity, and illness intrusions on psychological well-being. Results suggest competence processes play an important role in well-being. 相似文献

The widely held legend of historical conflict between science and religion cannot be sustained on the basis of research. Different sciences show different relationships to religion; the physical sciences show rapprochement, whereas the human sciences often are antagonistic to religion. Reconciling science and religion by regarding each as applicable to a different domain is rejected in favor of seeing them as complementary perspectives on the same phenomena. The science and theology of human nature represents a fruitful arena for the development of this approach. A key general requirement is the epistemological reconciliation of science and religion. 相似文献
