Hobson’s Conception of Definable Numbers

In this paper, I explore an intriguing view of definable numbers proposed by a Cambridge mathematician Ernest Hobson, and his solution to the paradoxes of definability. Reflecting on König’s paradox and Richard’s paradox, Hobson argues that an unacceptable consequence of the paradoxes of definability is that there are numbers that are inherently incapable of finite definition. Contrast to other interpreters, Hobson analyses the problem of the paradoxes of definability lies in a dichotomy between finitely definable numbers and not finitely definable numbers. To bypass this predicament, Hobson proposes a language dependent analysis of definable numbers, where the diagonal argument is employed as a means to generate more and more definable numbers. This paper examines Hobson’s work in its historical context, and articulates his argument in detail. It concludes with a remark on Hobson’s analysis of definability and Alan Turing’s analysis of computability.     

中文阅读中长距离回视引导机制的眼动研究

从记忆的角度, 探讨中文阅读中长距离回视的引导机制。采用眼动实验, 操纵了回视条件(实验1)、回视可见性(实验2)、目标词位置及词频变量。结果发现:与不阅读组相比, 阅读组的最初回视误差更小, 定位效率更高; 与可见组相比, 不可见组累积回视距离更大, 且难以正确定位目标; 目标词位置主效应显著, 而词频主效应不显著。结果表明, 回视具有空间选择性, 最初的回视由空间记忆引导, 最初回视后的修正眼跳在文本可见情况下才能正常进行, 而词频这一言语属性对回视没有显著影响, 本研究结果支持了空间编码假设。     

低阶层大学生的炫耀性消费:自尊补偿与地位追求

近年来低阶层大学生炫耀性消费负性事件频发,研究以补偿性消费理论为基础,考察低阶层大学生炫耀性消费的内因与外因。实验一通过比较高、低状态自尊条件下不同阶层被试的炫耀性消费倾向来考察自尊的作用,结果表明低阶层大学生的炫耀性消费倾向受到其状态自尊的调节; 实验二通过比较不同阶层被试对地位及非地位符号商品的支付意愿来考察商品符号价值的作用,结果表明低阶层大学生只有在商品具有地位符号价值时,才会表现出比高阶层大学生更强烈的炫耀性消费倾向。     

二胎环境下小学高年级“脱独”儿童父母教养方式与同胞关系:心理理论的中介作用

研究采用问卷集体施测,收集了788名小学高年级“脱独”儿童的父母教养方式、同胞关系以及心理理论的状况,探讨小学高年级“脱独”儿童父母教养方式对同胞关系的影响及心理理论作为中介变量的影响。结果表明:心理理论在父母教养方式中的父亲过分干涉、母亲情感温暖理解、母亲惩罚严厉、母亲过分干涉与同胞关系之间起完全中介作用; 心理理论在父亲情感温暖理解、父亲偏爱与同胞关系之间起部分中介作用。研究认为,良好的父母教养方式,有助于个体提高心理理论,并可能在一定程度上改善同胞关系。     

参照依赖和损失规避对个体收入分配公平判断的影响

收入分配公平判断是人们对自己收入所得公平与否的主观评价。通过对参照点和收入金额的控制,探讨参照依赖和损失规避对收入分配公平判断的共同影响。结果发现,(1)民众的收入公平判断受参照点的影响,在有参照点的情景下比无参照点情景下更感觉不公平;(2)不同工资水平下,民众的公平判断具有显著差异,而且民众对低于平均工资的“受损”比高于平均工资同等金额的“受益”赋予的公平感的权重更大,即存在得失感受的不对称;(3)不同的工资参照点、多得和少得的分配结果共同影响民众的公平判断,即损失规避在参照依赖对公平判断的影响中起调节作用。     

新型冠状病毒疫情影响下大学生对医生角色行为的道德判断研究

2020年初,在我国发生了新型冠状病毒引发的重大疫情,医生是战“疫”的重要角色,也是最受关注的职业群体。这次疫情是否改变了以往因医患矛盾而引发的大众对医生的道德判断?本研究采用徐科朋(2019)编制的道德判断材料,以非医护专业大学生为被试,用实验法分别比较了疫情前和疫情中大学生对医生道德和不道德行为的判断。结果发现:(1)疫情前大学生对医生在公平行为上的赞扬程度显著高于疫情中,疫情中大学生对医生在关爱、忠诚、权威行为上,赞扬程度显著高于疫情前。(2)在整体不道德行为上,疫情中大学生均对医生的评价比对照组严格。疫情前大学生对医生在背叛、颠覆行为上的评价要比对照组宽松。疫情中大学生对医生在伤害、背叛、堕落行为上的评价要比对照组严格。(3)疫情中,大学生对医生在整体不道德行为和各维度不道德行为上的评价较疫情前均更加严格。

Nonmonetary and nonreciprocal freecycling: Motivations for participating in online alternative giving communities

This research examines consumers' participation in a nonmonetary, nonreciprocal form of online consumer exchange wherein consumers may decide to give only, receive only, or both give and receive. Given the lack of financial incentives or relational norms that would traditionally drive participation in this societally beneficial consumption activity for which we advance the term alternative giving, this research examines consumers' participation motivations. Are consumers, as prior research suggests, motivated to participate in alternative giving activities on the basis of prosocial motives or for other reasons? Through a content analysis of the online Freecycle Network, we found that participation is driven primarily by fundamental consumer needs and wants, though other prosocial, less materialistic factors are also drivers. Our findings also identify an inconsistency in product categories between what givers offer and what receivers seek, suggesting that supply–demand imbalances can emerge within alternative giving communities.     

Influence of individual differences in working memory on the continued influence effect of misinformation

ABSTRACT

Misinformation often continues to influence people’s cognition even after being retracted (the continued influence effect of misinformation, CIE). The current research aimed to investigate whether the individual differences in the central executive function of WM and updating could influence the CIE of misinformation with varying relevance. The results showed that the individual differences in central executive function could significantly affect the CIE, especially for the high-relevant misinformation. While the individual differences in the updating ability had a weaker impact on the CIE in general and only negatively related to the CIE for the low-relevant misinformation. The study extends the understanding of the relationship between individual differences and the CIE from previous studies, which is in line with the mental-model-updating hypothesis, and offers a preliminary clue for identifying the persons vulnerable to the CIE of misinformation in the real world.
