This article confronts growing conservative opposition to abortion based on the claim that abortion is morally equivalent
to infanticide. By examining the relationship between moral skepticism and precautionary ethics the article promotes a completely
permissive position on abortion from conception to birth while consistently rejecting the possibility that such a position
entails permissive implications for infanticide. The article introduces and traces the implicit relationship between moral
skepticism, the precautionary principle and political liberalism.

In this commentary, I critically discuss the respective views of Gert and Beauchamp–Childress on the nature of so-called common
morality and its promise for enriching ethical reflection within the field of bioethics. Although I endorse Beauchamp and
Childress’ shift from an emphasis on ethical theory as the source of moral norms to an emphasis on common morality, I question
whether rouging up common morality to make it look like some sort of ultimate and universal foundation for morality, untouched
by the dialectics of time and reflective equilibrium, was an equally good move. As for Gert’s magisterial conception of common
morality, I conclude that certain elements of his system are controversial at best and woefully inadequate at worst. He has
a tendency to find in common morality what he himself put there, and his highly restricted conception of duties of assistance
strikes this reader as ad hoc, inadequately defended, and unworthy of a project whose goal is to lessen the amount of misery
in the world.

This study investigated whether Asian elephants can make relative quantity judgment (RQJ), a dichotomous judgment of unequal
quantities ordered in magnitude. In Experiment 1, elephants were simultaneously shown two baskets with differing quantities
of bait (up to 6 items). In Experiment 2, elephants were sequentially presented with baits, which could not be seen by elephants
in their total quantities. The task of elephants was to choose the larger quantity in both experiments. Results showed that
the elephants chose the larger quantity with significantly greater frequency. Interestingly, the elephants did not exhibit
disparity or magnitude effects, in which performance declines with a smaller difference between quantities in a two-choice
task, or the total quantity increases, respectively. These findings appear to be inconsistent with the previous reports of
RQJ in other animals, suggesting that elephants may be using a different mechanism to compare and represent quantities than
previously suggested for other species. 相似文献

How is the Confucian moral agent motivated to do what he or she judges to be right or good? In western philosophy, the answer to a question such as this depends on whether one is an internalist or externalist concerning moral motivation. In this article, I will first interpret Confucian ethics as role-based ethics and then argue that we can attribute to Confucianism a position on moral motivation that is neither internalist nor externalist but somewhere in between. I will then illustrate my claim with my reading of Mencius 6A4, showing that it is superior to readings found in the literature, which typically assume that Mencius is an internalist. 相似文献

判断与决策中的锚定效应 总被引:8,自引:0,他引:8
versky和Kahneman提出锚定与调整启发式以来,锚定效应在不同领域判断与决策研究中得到广泛验证,提出了不同类型的锚定效应、多种研究范式、心理机制的不同理论观点,以及锚定效应作为有关心理现象的内在作用机制。文章阐述了锚定效应的最新研究进展,提出应深化对锚的种类和形态研究,以丰富的技术手段发展锚定效应神经心理机制研究,系统地进行锚定效应影响因素研究,深入探讨锚定现象对人的心理与行为的正负面影响以及锚定效应与其他有关心理现象间的关系 相似文献

大学生偶发和外显编码中的自我参照效应 总被引:1,自引:0,他引:1
在自我参照范式中加入偶发编码加工方式,并采用R/K判断范式考察中国大学生在偶发编码和外显编码方式中的记忆成绩.结果发现:在R指标上,偶发编码方式和外显编码方式中均出现了自我参照效应和母亲参照效应;参照自我加工的记忆成绩显著高于参照母亲加工的记忆成绩;外显编码方式中的记忆成绩显著高于偶发编码方式的记忆成绩.结果提示,当需提高对信息的记忆成绩时,只要呈现自我线索就足够了,并不需要对其进行外显编码加工. 相似文献

主要探讨不同延时间隔和线索类型对遗忘元认知判断的影响。采用传统的学习判断任务,让被试学习40对无意义配对词,并告知随后进行测试,当呈现第一个词时,被试能够回忆与之配对的后一个词。让被试预测当延迟不同时间(5分钟、1天和1周)进行测试时,他们能够记住(学习判断)或者遗忘(遗忘判断)后一词的可能性。最后,要求被试回忆所有词对。结果发现延时间隔对学习判断和遗忘判断有相似的影响;学习判断的等级和相对准确性均高于遗忘判断,说明人们对记住和遗忘的线索很敏感;相比于学习判断,人们监测自己遗忘能力的信心不足。研究结果表明人们能够利用延时间隔和线索类型来预测未来的测验成绩,对遗忘的监测能力低于对记住的监测。 相似文献

Age‐related differences in sensory functioning, processing speed, and working memory have been identified as three significant predictors of the age‐related performance decline observed in complex cognitive tasks. Yet, the assessment of their relative predictive capacity and interrelations is still an open issue in decision making and cognitive aging research. Indeed, no previous investigation has examined the relationships of all these three predictors with decision making. In an individual‐differences study, we therefore disentangled the relative contribution of sensory functioning, processing speed, and working memory to the prediction of the age‐related decline in cognitively demanding judgment and decision‐making tasks. Structural equation modeling showed that the age‐related decline in working memory plays an important predictive role, even when controlling for sensory functioning, processing speed, and education. Implications for research on decision making and cognitive aging are discussed. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献
