汉字识别中部件组合的频率效应

用整字识别、整合识别等任务研究部件组合频率在汉字识别中的作用。发现部件组合频率可促进高频两部件合体字的识别（实验一）;在先后呈现两组成部件时这种作用仍然存在（实验二）;但在识别高频三部件左右型合体字时（实验三）,位于左边的部件组合表现出易化作用（田型字）;位于右边的部件组合表现出干扰作用（田型字）。部件组合有与部件类似的频率效应。     

电子商务中消费者购买决策及其影响因素

电子商务是随着计算机和互联网技术的发展而出现的一种新经济模式, 它正在广泛而深刻地影响着人们的购物观念和购物方式。网上购物是指通过互联网购买商品或享受服务, 也是通常所指的电子商务。国内外关于网上购物的研究缺乏从影响因素到中介作用最后到实际购买关系的整体研究框架。研究者从消费者角度提出了网上购物决策的整体框架, 拟采取访谈法、问卷调查、实验室模拟方法和服务器日志文件收集数据, 探讨我国文化背景下消费者的网上购买决策, 拟探明：影响消费者网上购买决策的因素; 风险认知和网上购物态度在模型中的中介作用; 产品类型、消费者类型及其与网上购物决策模式的关系。预期研究成果对我国电子商务购物环境的改善、电子商务网站的设计、网上营销策略的制定有着重要的意义。     

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.     

现阶段我国城市居民消费心理预期的性质与特点

采用自编《消费心理预期问卷》对1097名城市被试进行了研究,结果表明：1．《消费心理预期问卷》具有较高的信度和效度;2．消费心理预期是由五个因素构成的：宏观经济形势预期、个人生活与收入预期、政府经济政策预期、物价走势预期和突发事件预防预期;3．现阶段,我国城市居民的消费心理预期普遍比较消极．甚至悲观;4．影响消费心理预期的因素是多维的,其中?肖费者的性别、年龄、学历、工作单位和所在城市等变量都是直接影响心理预期的一些重要因素,即不同性别、年龄、学历、工作单位和城市的消费者对未来存在着不同的心理预期。     

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。     

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。     

消费决策中的零：零价格效应和零比较效应

数字“0”由于自身所具有的特性(最小的自然数和不可作为被除数),当其与商品的价格维度和属性维度相结合时会对消费者的决策产生影响。已有研究表明商品的零价格和零属性会对消费决策产生影响,即零价格效应和零比较效应。情绪和社会规范是零价格效应产生的心理机制,参照依赖则是零比较效应产生的心理机制。商品价格、商品类型和消费者的心理因素是零价格效应的边界条件;而选项的数量是零比较效应的边界条件。未来的研究可以从不同商品类型、不同社会规范、“价格-损失”与“价格-质量”、注意等角度对零价格效应进行深入研究;也可以从结构匹配模型和齐当别模型的角度进一步探索零比较效应的“比较”机制;可以探讨价格是否能被视为商品的“坏属性”,进而讨论零价格效应和零比较效应二者之间的关系。     

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。     

The Influence of Arbitrary Breakpoints on Judgments of Maximum Output

Consumers often wonder about the product's maximum output: the highest rotation speed of a blender or the best printing quality of a printer. We examine how the number of levels (e.g., a blender with 3 vs. 7 speeds) influences judgments of maximum product output. Objectively speaking, the number of levels is no more than a set of breakpoints in an already predetermined continuum from the product's minimum to maximum output. Nevertheless, because of the ubiquitous association between number of breakpoints and quantity in daily life, consumers do not simply view more levels as a signal of greater precision (i.e., giving consumers more control over the possible outputs). They also incorrectly believe that the product has greater power (i.e., a higher maximum output), even when such an inference is in conflict with diagnostic attribute information (e.g., watts). A series of five studies documents the phenomenon, its asymmetric nature, and its boundary conditions. Reliance on the inaccurate “more levels, more power” lay theory weakens when participants consider a reduction rather than an increase in number of levels, and it disappears when the consumer is presented with an explicit relationship between each level and its corresponding output value (e.g., level 4:400 W).
