If You Can't Change What You Believe,You Don't Believe It

I develop and defend the view that subjects are necessarily psychologically able to revise their beliefs in response to relevant counter-evidence. Specifically, subjects can revise their beliefs in response to relevant counter-evidence, given their current psychological mechanisms and skills. If a subject lacks this ability, then the mental state in question is not a belief, though it may be some other kind of cognitive attitude, such as a supposition, an entertained thought, or a pretense. The result is a moderately revisionary view of belief: while most mental states we thought were beliefs are beliefs, some mental states which we thought were beliefs are not beliefs. The argument for this view draws on two key claims: First, subjects are rationally obligated to revise their beliefs in response to relevant counter-evidence. Second, if some subject is rationally obligated to revise one of her mental states, then that subject can revise that mental state, given her current psychological mechanisms and skills. Along the way to defending these claims, I argue that rational obligations can govern activities which reflect on one's rational character, whether or not those activities are under one's voluntary control. I also show how the relevant version of epistemic ‘ought’ implies ‘can’ survives an objection which plagues other variants of the principle.     

论荀子的性情观

在近年出土的战国楚简中,“性”和“情”及其表达的思想特别引人注目,这不能不使我们重新思考传统文献特别是《荀子》中“性”“情”思想的含义。荀子论性,一面认同性乃自然成就,一如白纸;一面又认为它既有恶的倾向,又有善的倾向。荀子论情,是把它放在后天的位置上,并赋予广泛的内容,使之具有善恶一体、两端相对的特征。荀子论性情关系,一个在先,一个在后,经由心的统摄而联为一体,没有性,情无所出,没有情,性无由见。荀子的所谓性恶论,更准确地说应该是情恶论,这一层应该引起特别的注意。     

低卷入情境中品牌远延伸的成功机制

品牌延伸是近年营销学界的一个研究热点。多数实证研究表明,母品牌认知、母品牌好感、延伸类别与母品牌类别之间的拟合度以及母品牌特定联想对品牌延伸评价有重要的影响作用。然而,已有理论在解释跨类别的远距离延伸的成功机制上比较乏力。本研究采用实证方法对这一点进行了补充。考虑到初始延伸评价所处的低卷入情境,概念层级较高的品牌相关变量在品牌远延伸评价中有重要的影响作用,本研究对三个品牌相关变量：品牌类别固着度、品牌抽象性与功能性特点、品牌声誉的主效应采用三个控制实验进行了测查。实验结果表明,较小的类别固着度,较高的品牌抽象性特点,以及较高的品牌声誉是品牌远延伸获得成功的机制保证。     

汉字阅读中语音的通达与表征(Ⅰ)──字水平与亚字水平的语音及其交互作用

该文探讨了汉字语音激活的多层次性、普遍性、整字与声旁语音激活资源之间的交互作用等问题。以启动一命名为实验范式,结果表明：在汉字加工早期,汉字的语音得到了显著激活,而且这一激活发生在整字和声旁两个水平、高频和低频两种汉字中;整字与声旁的语音激活存在交互作用,而该交互作用受到整字与声旁的相对频率的影响。根据实验结果,该文提出：汉字整字和声旁的语音激活之间遵循“整字优先”和“高频优先”的原则交互作用。     

劣化部位对汉字识别的影响

首先自创“调制计算机显示法”制作视觉质量不佳的劣化汉字,后经识别实验的视觉检验,已论证此法的简便性和有效性。运用此法进行了两项劣化不同部位的识别实验,分别获得“劣化字的整合识别成绩与其劣化部位无关”的结果,并就此探讨了劣化条件下汉字的加工方式的整体性。     

来自基层医生的呼吁：重视社区医疗—《行医日记》选载

《行医日记》用行医实践说明了社区医疗的作用、地位、服务方式、服务内容以及社区医疗的诸多困难,社区医疗应该有其特定的社会地位和学术地位,以下几篇内容是根据日常所做、所想、所感而作的总结。对基层医疗的社区服务性质应该有个全新的认识。     

汉字识别中形音义激活时间进程的研究(Ⅰ)

分别采用基于语义的和基于语音的启动范畴判断作业,在不同的SOA条件下,考察高频汉字识别中形音义信息激活的相对时间进程。两个实验的结果表明,高频汉字形音义激活的时序为字形一字义一字音的顺序。这一结果揭示,高频汉字字义的提取更符合直通理论的预期。高频汉字的语音是自动激活的,但语音的激活可能发生在字义通达之后。     

Package Graphics and Consumer Product Beliefs

In recent years, marketers' tactics to increase product sales through health claims have been scrutinized by public policy makers. The culmination of this process was the passage of the National Labeling Education Act, which highly restricts the type, amount, and format of nutritional information conveyed on the package. In this investigation, we examine an under-explored aspect of the package—its colors and pictures—to determine what, if any, impact these aspects have on consumer beliefs regarding important product characteristics. We find that even when very concrete verbal information is used, graphical representations have a significant and long-term effect on product beliefs and purchase intentions.     

Searching for the Roots of the Circumstantial Ad Hominem

This paper looks into the known evidence on the origins of the type of argument called the circumstantial ad hominemargument in modern logic textbooks, and introduces some new evidence. This new evidence comes primarily from recent historical work by Jaap Mansfeld and Jonathan Barnes citing many cases where philosophers in the ancient world were attacked on the grounds that their personal actions failed to be consistent with their philosophical teachings. On the total body of evidence, two hypotheses about the roots of the circumstantial ad hominem are considered. One is that it came from Aristotle through Locke. The other is that it may have had separate roots in these ancient philosophical writings that criticized philosophers for not practicing what they preached.     

Are the Russians as Unhappy as they say they are?

Since the 1980s, several polls in Russia have included questions about happiness. The responses to these questions were quite similar. Average happiness was low in comparison to other nations and declined over time. Ten years after the fall of communism Russians are less happy than during the communist period.There are doubts about the validity of these self-reports. One source of doubt is that these data may not reflect Russians' self-appraisals adequately, due to distortions in translation and a differential response bias. A second misgiving is that true discontent could be rather superficial, and be largely due to unfavorable comparison with the West and folklore of negativism.These qualms are checked in this article. It appears that the Russians are as unhappy as they say they are, and that they have good reasons to be so. The current unhappiness is not due to the Russian national character, but has more to do with the troublesome transitions taking place in Russian society.
