The Domain‐specific Risk‐taking scale was designed to assess risk taking in specific domains. This approach is unconventional in personality assessment but reflects conventional wisdom in the decision community that cross‐situational consistency in risk taking is more myth than reality. We applied bifactor analysis to a large sample (n = 921) of responses to the Domain‐specific Risk Taking. Results showed that, in addition to domain‐specific facets, there does appear to be evidence for a general risk‐taking disposition. And this general appetite for risk appears to be useful for predicting real‐world outcomes. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

The θ′′-Al3Cu phase plays an important role in the precipitation process of Al–Cu alloys. This phase has a sandwich structure—every two {200}Cu layers are separated by three {200}Al layers. To analyse the formation mechanism of this structure, the elastic strain energy of the {200}Cu and {200}Al layers, and the chemical bonding energy that reflects the interaction between the electrons in Cu and neighbouring Al atoms are calculated and analysed by first-principles calculations, projected density of states and Bader analysis. Our computation results reveal that this sandwich structure is energetically preferred in the competition of elastic strain and chemical bonding energies. To minimise the elastic strain energy of {200}Al and {200}Cu layers, the {200}Cu layers prefer being apart from each other, whereas the chemical bonding energy favours the opposite arrangement because the intermetallic bond between Al and Cu atoms may form through p-d hybridization.  相似文献

The presence of emotional words and content in stories has been shown to enhance a story’s memorability, and its cultural success. Yet, recent cultural trends run in the opposite direction. Using the Google Books corpus, coupled with two metadata-rich corpora of Anglophone fiction books, we show a decrease in emotionality in English-speaking literature starting plausibly in the nineteenth century. We show that this decrease cannot be explained by changes unrelated to emotionality (such as demographic dynamics concerning age or gender balance, changes in vocabulary richness, or changes in the prevalence of literary genres), and that, in our three corpora, the decrease is driven almost entirely by a decline in the proportion of positive emotion-related words, while the frequency of negative emotion-related words shows little if any decline. Consistently with previous studies, we also find a link between ageing and negative emotionality at the individual level.  相似文献

The present study investigated whether another individual’s gaze direction influences an observer’s affective responses. In Experiment 1, subjective self-ratings and an affective priming paradigm were employed to examine how participants explicitly and implicitly, respectively, evaluated the affective valence of direct gaze, averted gaze, and closed eyes. The explicit self-ratings showed that participants evaluated closed eyes more positively than direct gaze. However, the implicit priming task showed an inverse pattern of results indicating that direct gaze was automatically evaluated more positively than closed eyes were. Experiment 2 confirmed that the opposite patterns of results between the two tasks were not due to differences in presentation times of the gaze stimuli. The results provide evidence for automatic affective reactions to eye gaze and indicate a dissociation between explicit and implicit affective evaluations of eyes and gaze direction.  相似文献

本文回顾了近40年中国老年心理学的研究成果,并从研究主题角度与美国老年心理学研究进行了比较。发现中国老年心理学主要聚焦于老年人心理健康研究,同时也在老年人家庭人际关系和社会支持领域研究有较为丰富的研究成果。但国内对老年人的认知能力、人格、情绪情感探讨较少,既缺少前沿的基础研究,也缺少对复杂能力、复杂情感等的系统研究。结合中国人口老龄化现实,本文提出了21世纪中国老年心理学的未来研究取向:基础研究和应用服务研究的双向结合,中国文化特色取向,个体-环境交互作用取向和个体差异取向。  相似文献

Background and objectives: Repressors tend to report less negative emotion and to describe challenges as less stressful, yet tend to exhibit higher rates of cardiovascular disease. While repressive coping has been shown to be associated with exaggerated physiological reactivity to novel stress, we sought to establish if elevated responses persisted across repeated exposure.

Design and methods: In a sample of 86 healthy female adults, a verbal-autonomic response dissociation index of repressive coping was computed. Participants were exposed to two consecutive stress tasks, with analyses based on comparisons of consecutive stress responses.

Results: Analysis of covariance demonstrated significant differences across the study on diastolic blood pressure and cardiac output, as a function of repressive coping. Repressors showed elevated reactions to both stress tasks; however, cardiac output responses to the second task were more muted indicating that repressive coping was associated with successful adaptation to recurrent stress. Nevertheless, repressive copers maintained an exaggerated cardiovascular responses to recurrent stress.

Conclusions: The present study identifies that repressive coping may be associated with increased risk of cardiovascular disease development through elevated cardiovascular reactions to both novel and recurrent stress.  相似文献

心理不安全感是指人们对可能遭受的伤害与威胁的担忧与焦虑。当下, 许多个体都是在心理不安全的状态下进行决策。对于心理不安全状态下的风险偏好规律, 现有研究得到了矛盾的结果。此外, 心理安全感对风险偏好的作用机制尚不明确。本研究聚焦心理安全感对风险偏好的影响, 考察心理安全感的补偿机制在其中的中介作用, 并探讨选项分布情况在其中的调节作用, 以此揭示心理安全感为何及如何作用于风险偏好。研究结果将有助于明确决策者在心理不安全状态下的风险偏好规律, 从而完善现有的风险决策理论。同时, 为公共管理政策制定提供科学依据。  相似文献

Abstract: In this article I identify the conceptual tools needed to establish claims for the existence of conceptual ties, along with the principles governing the use of those tools, and present a model of conceptual analysis. I identify and justify those principles in the light of the conditions for the meaningfulness of expressions in language, which I extract from an analysis of the concept of meaning. The conclusions of this analysis are organized into a schematic model of the workings of a language. According to this model, the meaning of every word in any language is determined by its role in the systematic mapping of all possible states of affairs included in its conceptual scheme.  相似文献
