Being student leaders or ‘ordinary’ students: Children's emotional experiences of relationships with others in a Chinese school

The student leader system is commonly used in Chinese schools. Student leaders are children who are elected by classmates, then assigned by teachers, to be responsible for monitoring classmates' behaviour. Based on the data collected through an intensive ethnographic study in a rural primary boarding school in China in 2016, this article discusses emotional experiences in peer relationships reported by both student leaders and other ‘ordinary’ students, who were not student leaders. The article argues that China's student leader system is likely to create hierarchical relationships between student leaders and ‘ordinary’ students, and exposes ‘ordinary’ students to the potential risk of being exploited by student leaders. The article also argues that because of this student leader system and relevant student evaluation values, student leaders and ‘ordinary’ students all feel stressed when they are building up and maintaining peer relationships, such as friendships, with each other.

When is the Wilcoxon–Mann–Whitney procedure a test of location? Implications for effect-size measures

The Wilcoxon–Mann–Whitney procedure is invariant under monotone transformations but its use as a test of location or shift is said not to be so. It tests location only under the shift model, the assumption of parallel cumulative distribution functions (cdfs). We show that infinitely many monotone transformations of the measured variable produce parallel cdfs, so long as the original cdfs intersect nowhere or everywhere. Thus there are infinitely many effect sizes measured as shifts of medians, invalidating the notion that there is one true shift parameter and thereby rendering any single estimate dubious. Measuring effect size using the probability of superiority alleviates this difficulty.     

Misunderstandings and omissions in textbook accounts of effect sizes

There have been frequent attempts in psychology to reduce the reliance on null hypothesis significance testing (NHST) as the criterion for establishing the importance of results. Many authorities now recommend the reporting of effect sizes (ESs) as a supplement or alternative to NHST. However, there is extensive specialist literature highlighting problems associated with the use and interpretation of ESs. A review of the coverage of ESs in over 100 textbooks on statistical analysis in behavioural science revealed widespread neglect of ESs and the relevant critical issues that have widespread coverage in the more specialist literature. For example, many textbooks claim that ESs should be interpreted as a simple measure of the practical real-world importance of a result despite the fact that ESs are profoundly influenced by features of design and analysis strategy. We seek to highlight areas of misunderstanding about ESs found in the pedagogical literature in the light of the more specialist literature and make recommendations to researchers for the appropriate use and interpretation of ESs. This is critical as statistics textbooks have a crucial role in the education of researchers.     

中国神话中的具身心理学思想探索

西方“具身认知”心理学与赋存在中国文化里的以“天人合一”为核心的“体知”心理学思想息息相通, 而中国文化又有其独异于西方文化的“身体”智慧。文化的源头实为神话。追根溯源, 本文主要从具身认知的视阈中将中西方神话中“身体”的角色两相比照, 首先从本体论维度以现象学诠释的方法来描述神话的身体母体是如何生成的, 并以天地开辟神话、万物肇始神话和人类起源神话为例揭示中国“身体”的本体论特色—— 一元论; 其次再从空间维度以概念隐喻的理论来剖析神话的身体现象学场域是如何延展的, 并从物我同一角度、天人交感角度和人神相通角度来彰显中国“身体”的空间维度特色——气论; 最后再从时间维度以社会建构理论来解构神话的身体是如何在时间场域中流变的; 并从社会、文化和历史三个层面来表达中国“身体”的时间维度特色——易论。通过从中国神话故事中挖掘中国传统文化中独有的“具身智慧”, 以期为建立中国人自己的科学心理学起抛砖引玉之用。     

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。     

汉语复合词视觉识别的时间进程：基于同形语素的行为与ERP证据

基于同形语素抑制效应, 本研究探讨了汉语复合词视觉识别中的形音义激活进程。结果发现：(1) 同形异音、同形同音、相同条件相对于控制条件都产生了语素启动效应; (2) 在P2、晚期N400成分上, 同形同音条件与控制条件更为接近, 但与同形异音及相同条件差别显著; (3) 在早期N400成分上, 同形同音条件与相同条件更为接近, 但与同形异音条件差别显著。研究表明, 汉语复合词的视觉识别的早期阶段可能为基于词位的形态-正字法加工, 字形匹配与音位信息是首要影响因素, 但语义是否介入仍未可知; 而晚期阶段则可能为基于词条的形态-语义加工, 主要涉及语义竞争与选择。本研究结果支持了McClelland等学者提出的“平行分布加工模型”。     

小学低段汉字识别和听写的发展轨迹：语素意识的预测作用

汉字识别和听写是字词水平上两项重要的读写技能。对127名一年级儿童进行了两年4个时间点的追踪调查, 通过测查儿童的一般认知能力、语音意识、正字法意识和语素意识(包括同音语素意识、复合语素意识), 探讨影响儿童汉字识别和听写发展的因素。利用潜变量增长模型, 结果发现：(1)汉字识别呈线性发展趋势, 听写呈先快后慢的非线性发展趋势, 二者均存在补偿效应; (2)语素意识显著预测了汉字识别的起始水平和发展速度, 但语素意识对听写的起始水平和发展速度均不具有显著的预测作用。研究结果表明儿童入学初始的汉字识别和听写水平并不决定后期的发展速度; 语素意识对儿童汉字识别和听写发展的作用不同。     

Do incompatible alternatives in a testimony affect witness credibility?

The qualitative regulation of grain size allows witnesses to increase the accuracy of their reports by adding alternatives (e.g., “the robber concealed his face with a mask, with a stocking, or with a balaclava”). However, such answers may include incompatible alternatives which may make police officers and juries distrust witnesses. In four preregistered experiments, we tested the effect of information with incompatible alternatives on witness credibility. In Experiments 1a, 1b, and 1c, we presented two short testimonies, one with incompatible alternatives and another without and credibility was lower with incompatible alternatives. In Experiment 2, we told participants that witnesses could report several alternatives and the effect was reduced. We explain the effect of incompatible alternatives on credibility from participants' inferences that a witness producing an answer with incompatible alternatives is not confident in their memory and a failure to fully appreciate the advantages of adding alternatives.     

Image-size disparity reduces difference detection in face matching

Face matching is the act of deciding whether two facial images depict the same person or different people. The real-world face-matching task of checking photo IDs typically occurs under conditions of image-size disparity: A small picture is compared with a life-size face. We examined the effect of image-size disparity on face-matching accuracy. In three experiments, subjects were presented with pairs of equivalently or disparately sized images that depicted the same person or different people. Subjects made same/different judgments and, in two experiments, also reported confidence. Difference detection was significantly poorer given disparate (versus equivalent) image size. Confidence was significantly higher when responses were correct versus incorrect. These findings held whether viewing and decision time was unlimited or limited. Our results raise the practical concern that image-size disparity may undermine difference detection in ID checking, while also indicating that people have some insight into the accuracy of their face-matching judgments.
