When people anticipate that future temptations may undermine valued goals, they use a number of prospective self-control strategies (or “precommitment devices”) to increase the likelihood of future self-control success. Little is known, however, about the conditions under which people are more or less likely to use them. Drawing from construal level theory (e.g., Trope & Liberman, 2003), we argue that people are more likely to engage in prospective self-control when they construe events more abstractly (at higher-level construals). Results from two experiments demonstrated that higher-level construals promote use of two well-documented prospective strategies: choice bracketing and self-imposing punishment. Higher-level construals thus appear to enhance people's efforts to protect their valued goals from anticipated temptations. 相似文献

Glaciers serve as early indicators of climate change. Over the last 35 years, our research team has recovered ice-core records of climatic and environmental variations from the polar regions and from low-latitude high-elevation ice fields from 16 countries. The ongoing widespread melting of high-elevation glaciers and ice caps, particularly in low to middle latitudes, provides some of the strongest evidence to date that a large-scale, pervasive, and, in some cases, rapid change in Earth''s climate system is underway. This paper highlights observations of 20th and 21st century glacier shrinkage in the Andes, the Himalayas, and on Mount Kilimanjaro. Ice cores retrieved from shrinking glaciers around the world confirm their continuous existence for periods ranging from hundreds of years to multiple millennia, suggesting that climatological conditions that dominate those regions today are different from those under which these ice fields originally accumulated and have been sustained. The current warming is therefore unusual when viewed from the millennial perspective provided by multiple lines of proxy evidence and the 160-year record of direct temperature measurements. Despite all this evidence, plus the well-documented continual increase in atmospheric greenhouse gas concentrations, societies have taken little action to address this global-scale problem. Hence, the rate of global carbon dioxide emissions continues to accelerate. As a result of our inaction, we have three options: mitigation, adaptation, and suffering. 相似文献

Nuclear energy has received substantial recent attention, marketed as a ‘green’ solution to global climate change (GCC) with calls for new reactors. However, considerable debate exists about whether it represents a viable solution to GCC. Given the complexity and urgency of the issue, a full and balanced debate is desirable. Since media play an important role in shaping public perception, we examined print media coverage of proposed reactors in Georgia—one site in the southeastern United States, which has been the focus of such proposals. We analysed the content of editorials and news articles from two local newspapers—the Augusta Chronicle and Atlanta Journal‐Constitution. The former exclusively published pro‐nuclear opinion pieces whereas the latter published a mix of pro‐ and anti‐nuclear opinions. The majority of news articles in both newspapers generally presented balanced arguments. Pro‐ and anti‐nuclear arguments most often reflected economic and environmental benefits and risks, whereas informational text primarily detailed regulatory processes and financing. Findings suggested that informational text was not necessarily ‘neutral’, sometimes masking covert pro‐ and anti‐nuclear content. Implications for how findings might shape public opinion and strategies for shaping media and extending public deliberation are discussed. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

Positive Affect and Flexibility: Overcoming the Precedence of Global over Local Processing of Visual Information 总被引:2,自引:0,他引:2
Previous findings on the relationship between positive mood and global processing are often based on visual matching tasks
that involve a choice between global and local strategies. Preferences for global processing in positive mood, however, do
not imply a reduced ability to process locally. The present experiment tested the assumption that positive affect increases
flexibility in cognitive processing as indicated by the ability to overcome global precedence, and to respond rapidly to non-dominant
(local) features when the task necessitates it. Consistent with expectations, participants responded significantly faster
to local targets after positive compared to neutral and negative prime words. The typical precedence of global over local
processing observed after neutral and negative prime words was reversed after positive prime words. Findings support the assumption
that positive affect increases cognitive flexibility. Furthermore, findings suggest that mood-related preferences in global
versus local processing cannot be generalized to processing ability. 相似文献

民族国家的架构尽管日益式微,但它在组织全球化经济、全球化政治和正在形成的全球公民社会中仍然占有首要地位。民族国家不是在消亡,而是正在被重新想象、重新设计、重新调整方向以回应一系列挑战。相应地,对国家的研究在现时代仍然具有重要意义,在全球化背景下,全球资本、全球公民社会、全球治理与民族国家的关系研究构成了国家理论的新形态。 相似文献

2岁儿童延迟性自我控制及家庭因素的相关研究 总被引:14,自引:0,他引:14
摘要研究考察2岁儿童延迟性自我控制行为的发展水平及其家庭影响因素。对86名17.5到28.5个月的儿童在画笔和食物为诱惑物的两种延迟满足情境中的行为进行实验室录像观察。同时以问卷法了解其父母教养行为、婚姻质量及亲子关系等家庭因素。结果显示:(1)2岁儿童已经具有延迟性自我控制行为.且存在性别差异。(2)家庭教养态度,尤其是母亲的教养态度对儿童自我控制行为有显著预测作用;(3)母亲所体验到的家庭生活的和谐程度能显著地预测儿童延迟性自我控制行为;(4)在控制了性别、婚姻质量及家庭教养态度后,亲子关系的作用不显著。 相似文献

采用改编后的“整体自尊问卷”和“交谈自尊问卷”筛选出整体自尊和交谈自尊高低不同的四组被试,通过模拟现实人际互动情境,在评价人对被试的交谈表现提供不同评价(肯定或否定)及表达不同交友态度(接受或排斥)的条件下,考察了整体自尊与特殊自尊对人际互动过程中自我确认倾向的影响,结果表明:(1)不论社交需求是否获得满足,即整体自尊是否得以维持,被试的自我确认倾向都只受特殊自尊的调节;(2)在社交需求和一致性需求同时获得满足,即整体自尊与特殊自尊均得以维持时,被试的自我确认倾向受整体自尊和特殊自尊的共同调节;(3)在社交需求和一致性需求未同时获得满足,即整体自尊和特殊自尊不能同时得以维持时,高整体自尊者的自我确认倾向受特殊自尊的调节,而低整体自尊者未表现出自我确认的倾向。 相似文献

延迟满足是一种心理成熟的表现,专指一种甘愿为更有价值的长远结果而放弃即时满足的抉择取向,以及在等待期中展示的自我控制能力。本文通过论述儿童的自我延迟满足能力的发展的特点以及影响其自我延迟满足能力的发展的因素,探索了如何教育儿童自我延迟满足能力的有效途径,对幼儿健康成长和发展具有一定的指导作用。 相似文献

The idea that payment for research participation can be coercive appears widespread among research ethics committee members, researchers, and regulatory bodies. Yet analysis of the concept of coercion by philosophers and bioethicists has mostly concluded that payment does not coerce, because coercion necessarily involves threats, not offers. In this article we aim to resolve this disagreement by distinguishing between two distinct but overlapping concepts of coercion. Consent-undermining coercion marks out certain actions as impermissible and certain agreements as unenforceable. By contrast, coercion as subjection indicates a way in which someone’s interests can be partially set back in virtue of being subject to another’s foreign will. While offers of payment do not normally constitute consent-undermining coercion, they do sometimes constitute coercion as subjection. We offer an analysis of coercion as subjection and propose three possible practical responses to worries about the coerciveness of payment. 相似文献

老年人的联结记忆随年龄增长而出现普遍损伤, 这种增龄性联结记忆损伤究竟是因捆绑功能受损导致的特定损伤还是因整体认知机能受损导致的信息表征能力的整体损伤, 还存有争论。以Naveh-Benjamin (2000) 的联结损伤假说(ADH)为代表的特定损伤观认为, 增龄性联结记忆损伤与老年人捆绑不同项目和提取这些捆绑的特定加工过程的损伤有关; 而以Benjamin (2010) 的DRYAD模型为代表的整体损伤观则认为, 增龄性联结记忆损伤与老年人因老化而导致的记忆保持精度的整体损伤有关。二者在基本观点、实验支持及存在问题上各有侧重。此外, 影响增龄性联结损伤的因素还可大致分为刺激信息特性、被试主体特点两方面。同时强调未来研究不仅要关注老年人联结损伤的认知机制和影响因素, 更应关注其实际应用和临床指导价值。 相似文献
