Faith and reason and physician-assisted suicide.

Aquinas's conception of the relationship of faith and reason calls into question the arguments and some of the conclusions advanced in contributions to the debate on physician-assisted suicide by David Thomasma and H. Tristram Engelhardt. An understanding of the nature of theology as based on revelation calls into question Thomasma's theological argument in favor of physician-assisted suicide based on the example of Christ and the martyrs. On the other hand, unaided reason calls into question his assumptions about the nature of death as in some cases a good for the human person. Finally, if Aquinas is right about the relationship of faith and reason, Engelhardt's sharp contrast between "Christian" and "secular" approaches to physician-assisted suicide needs reconsideration, although his conclusions about physician-assisted suicide would find support.     

预见:情景记忆的未来投射与重构

预见是对有关个人的未来事件进行模拟的过程。相关的研究从几个方面展开:从比较心理学的角度探讨预见能力的种系发生图谱,从发展心理学的角度考察预见能力的发生发展状况,从认知神经科学的角度揭示预见过程的认知机制和神经基础。未来的研究应该补充和修正预见能力的种系发生图谱,揭示发展过程中预见能力与其他能力的关系,进一步考察卷入预见过程脑区之间的特定神经通路,并提高和拓展其社会应用的价值和范围。     

幼儿预见能力的发展及与抑制控制、心理理论的关系

预见是预测未来会发生什么或者需要什么的能力,是对未来自我状态进行的推理。该研究由两部分实验组成。实验1以3～5岁幼儿为研究对象,采用Atance和Meltzoff(2005)的非言语研究范式,探讨了预见能力的发展特点。结果表明,4岁以后,幼儿能够根据未来的需要选择适宜的物品。实验2以4～6岁幼儿为研究对象,考察了预见与抑制控制和心理理论能力的关系。结果发现,抑制控制对幼儿的预见能力存在直接的预测效力,而心理理论则是通过抑制控制作为中介变量间接地作用于预见过程。     

Deconstructing the Doctrine of Double Effect

This paper examines the doctrine of double effect as it is typically applied. The difficulty of distinguishing between what we intend and what we foresee is highlighted. In particular, Warren Quinn's articulation of that distinction is examined and criticised. It is then proposed that the only credible way that we can be said to foresee that a harm will result and mean something other than that we intend it to result, is if we are not certain that that harm will result. The ramifications of this are explored. The paper concludes with a moral evaluation of a variety of cases that have harmful outcomes. It is recommended both that we abandon the doctrine of double effect and that we cease to describe cases with harmful outcomes in a dishonest way.     

Do preschoolers save to benefit their future selves?

Using a new paradigm for measuring children's saving behaviors involving two marble games differing in desirability, we assessed whether 3-, 4-, and 5-year-olds saved marbles for future use, saved increasingly on a second trial, saved increasingly with age, and were sensitive to the relative value of future rewards. We also assessed whether performance on the saving paradigm was related to theory of mind performance. Children saved significantly more marbles on the second trial than the first and saved significantly more when a future reward was more desirable than a present reward (rather than the reverse). However, older children did not save significantly more than younger children. Performance on one of two false belief tasks was not correlated with saving behavior and performance on the other was only marginally correlated with the number of marbles saved on trial 2. Implications for children's future thinking and comparative research are discussed.     

小学高年级学生的学习判断绝对准确性及预见偏差

本研究以小学高年级学生为被试,选取高熟悉度的具体名词组成的联结词对为实验材料,考察不同判断模式下学习判断的准确性及预见偏差。研究发现:(1)小学高年级学生的学习判断绝对准确性存在年级差异。总体来看,小学六年级学生在即时判断和延迟判断模式下都具有较好的绝对准确性,而四年级和五年级学生在即时判断时出现显著的高估,而在延迟判断模式下具有较好的绝对准确性。具体分析正向词对和反向词对的准确性发现,在即时判断模式下,五、六年级学生的正向联结词对有较好的准确性,而四年级的正向联结词对出现高估;三个年级的学生的反向词对都出现高估。在延迟判断模式下,三个年级学生在正向词对和反向词对上都有较好的准确性。(2)小学五年级学生的学习判断开始出现预见偏差。(3)延迟判断能够提高小学高年级学生的学习判断准确性,减小甚至消除预见偏差。     

Don't Predict the Future–Direct it! Comments on the intellectual history,the Logical and Applicative Visibility,and the Underlying Assumptions of Directed Evolution (DE)

It is obvious that there are patterns of cultural change—evolution in the neutral sense—and any theory of cultural change worth more than a moment's consideration will have to be Darwinian in the minimal sense of being consistent with the theory of evolution by natural selection of Homo sapiens.

Understanding deliberate practice in preschool-aged children

Deliberate practice is essential for skill acquisition and expertise and may be a direct consequence of episodic foresight. However, little is known about how deliberate practice develops in children. We present two experiments testing children's ability to selectively practise a behaviour that was going to be useful in future and to reason about the role of practice in skill formation. Five-year-olds demonstrated an explicit understanding of deliberate practice both in selectively choosing to practise a future-relevant skill and in predicting skill change in others based on their practice. Four-year-olds showed some capacities, but failed to demonstrate consistent understanding of the relationship between practice and skill improvement. Children's understanding of this relationship was significantly related to their understanding of how information leads to knowledge, suggesting that both may draw on similar cognitive developmental changes.
