发展性计算障碍儿童的数量转换缺陷

本研究拟考察发展性计算障碍儿童的认知缺陷成因。实验1要求被试在三种形式(点/点,数/数,点/数)下进行数量比较,实验2仅将点集替换为汉字数字词。结果表明障碍组和正常组在数/数、点/数和汉字/汉字比较任务上的成绩存在显著差异,而在点/点和汉字/汉字比较上没有差异。据此推论,计算障碍儿童符号加工能力受到损伤,符号与非符号数量转换能力存在缺陷,但非符号加工能力和不同符号间数量转换没有缺陷,支持语义提取缺陷假设。     

汉字刺激质量和频率在N400上的交互

采用事件相关电位,运用无启动的同一字判断（靶字延迟反应）范式,以大学生为被试探讨汉字刺激质量和频率是否具有交互作用。行为结果显示,刺激质量和频率在反应时上存在交互作用。脑电结果显示,重度模糊诱发了更大的N250和N400,且刺激质量和频率在N400上存在交互作用。结论是,汉字刺激质量和频率在反应时和N400上存在交互作用,表明在汉字识别中存在串级加工,支持IA模型。     

不同社会情境对儿童奖惩分配公平性的影响

为探讨社会排斥和社会接纳情境下儿童奖惩分配公平性,研究采用个体-偶然排斥范式和第三方奖惩分配范式,对8~9岁儿童奖惩分配公平性行为和奖惩分配公平性判断进行研究,结果发现：（1）社会排斥组被试的奖惩分配公平性行为显著多于社会接纳组,奖惩分配不公平性行为显著少于社会接纳组。9岁组被试的奖惩分配公平性行为显著多于8岁组,奖惩分配不公平性行为显著少于8岁组;（2）社会排斥组被试的奖惩分配公平性判断显著高于社会接纳组,9岁组被试的奖惩分配公平性判断显著高于8岁组,奖惩分配不公平性判断显著低于8岁组。结论：社会情境影响儿童的奖惩分配公平性,在排斥情境下,8~9岁儿童的奖惩分配公平性明显提升;8~9岁儿童的奖惩分配公平性随年龄增长有上升趋势。     

小学生在交通情境中的视觉搜索：发展的观点

为探讨小学生在交通情境中的视觉搜索发展特点,研究以一、二、四和六年级小学生,以及成人为被试,采用“找不同”任务和过马路决策眼动任务进行实验。结果发现,一、二年级小学生“找不同”的效率低于成人;一年级小学生冒险及错失过马路比例均较高;小学生的眼跳特征与成人相似,但对兴趣区的关注低于成人;女生错失过马路比例高于男生,视觉搜索水平及搜索策略的性别差异不显著。研究表明,小学生的视觉搜索能力随年龄逐渐提高,但搜索的有效性低于成人,性别分化不明显。     

Psychometric Properties of a Chinese Version of the Moral Attentiveness Scale

This study focuses on the reliability and validation of the Chinese version of the Moral Attentiveness Scale. Factor analysis confirmed that the scale includes two factors: perceptual moral attentiveness and reflective moral attentiveness. Moral attentiveness is negatively correlated with normlessness and positively associated with internalization and symbolization, moral identity, and other academic dishonesty behaviors. Reflective moral attentiveness moderated the relationship between formalism and unethical decision making. All results showed that the Chinese version of the Moral Attentiveness Scale has satisfactory psychometric properties and is a valid and reliable measurement of moral attentiveness in the Chinese population.     

Agents of Prosociality: Agency Affirmation Promotes Mutual Prosocial Tendencies and Behavior Among Conflicting Groups

Members of conflicting groups are motivated to restore their ingroup's agency, leading to antisocial tendencies against the outgroup. The present research tested the hypothesis that affirming conflicting groups' agency would increase their members' mutual prosociality. The effectiveness of agency affirmation was demonstrated in three contexts of conflict between groups: Switzerland and the EU following the 2014 referendum (Study 1), Israelis and Palestinians (Study 2), and Israeli rightists and leftists (Study 3). Study 1 found that in a nonconflictual context Swiss participants prioritized their moral (prosocial) over agentic goals, yet in the context of conflict with the EU, they prioritized their agentic over moral goals. This “primacy‐of‐agency” effect, however, was eliminated once their ingroup's agency was affirmed. Studies 2 and 3 demonstrated the positive effect of agency affirmation on prosociality among Israelis referring to Palestinians and Israeli rightists and leftists referring to the adversarial political camp. This effect was mediated by group members' readiness to relinquish some power for the sake of morality. Pointing to the importance of the affirmation's specific content, Studies 2 and 3 demonstrated that morality affirmation failed to increase prosociality. As such, the present research puts forward a promising strategy to reduce hostility and promote prosociality between conflicting groups.     

Sikh millennials of the ‘kirtan generation’ in the making of an ‘American Sikhism’

ABSTRACT

This essay focuses on the millennial generation of Sikhs in the United States. Based on extended ethnographic research in Sikh communities, the author explores the role of Sikh millennials in the making of an ‘American Sikhism’, the contours of which are taking shape having followed after the explosive growth of gurdwara communities – and the educational, social, and other resources they provide – which were largely made possible by the affluence of Sikh communities beginning with the previous ‘Brain Drain’ generation. In particular, the author discusses this ‘kirtan generation’ of Sikhs, educated in gurdwara schools, and their growing leadership of Sikh communities.     

Crisis,Biology, Ecology: A New Starting-Point for Phenomenology?

The crisis of European sciences in Husserl’s late work diagnoses Galilean science as specifically and necessarily losing touch with the intuitive evidence that would legitimate it due to its reliance on a formal-mathematical conceptual apparatus. While the vast majority of Husserl’s late work was focussed on a critique of the formal-mathematical paradigm of the physical science of nature, at several points the possibility of biology as the exemplary science is raised to suggest that the lack of a reliance on formal-mathematical conceptual language would mean that a systemic crisis would not occur in such a case. This investigation considers the grounds for the expectation that biology would not engender a crisis, suggests that a paradigmatic role for ecology would more adequately address this expectation, and finally claims that the question of the relation between a specific exemplary science and transcendental phenomenology is not fully resolved even in this case.     

Testing autocorrelation and partial autocorrelation: Asymptotic methods versus resampling techniques

Autocorrelation and partial autocorrelation, which provide a mathematical tool to understand repeating patterns in time series data, are often used to facilitate the identification of model orders of time series models (e.g., moving average and autoregressive models). Asymptotic methods for testing autocorrelation and partial autocorrelation such as the 1/T approximation method and the Bartlett's formula method may fail in finite samples and are vulnerable to non-normality. Resampling techniques such as the moving block bootstrap and the surrogate data method are competitive alternatives. In this study, we use a Monte Carlo simulation study and a real data example to compare asymptotic methods with the aforementioned resampling techniques. For each resampling technique, we consider both the percentile method and the bias-corrected and accelerated method for interval construction. Simulation results show that the surrogate data method with percentile intervals yields better performance than the other methods. An R package pautocorr is used to carry out tests evaluated in this study.
