Short‐term numerosity training promotes symbolic arithmetic in children with developmental dyscalculia: The mediating role of visual form perception

Studies have shown that numerosity‐based arithmetic training can promote arithmetic learning in typically developing children as well as children with developmental dyscalculia (DD), but the cognitive mechanism underlying this training effect remains unclear. The main aim of the current study was to examine the role of visual form perception in arithmetic improvement through an 8‐day numerosity training for DD children. Eighty DD children were selected from four Chinese primary schools. They were randomly divided into the intervention and control groups. The intervention group received training on an apple‐collecting game, whereas the control group received an English dictation task. Children's cognitive and arithmetic performances were assessed before and after training. The results showed that the intervention group showed a significant improvement in arithmetic performance, approximate number system (ANS) acuity, and visual form perception, but not in spatial processing and sentence comprehension. The control group showed no significant improvement in any cognitive ability. Mediation analysis further showed that training‐related improvement in arithmetic performance was fully mediated by the improvement in visual form perception. The results suggest that short‐term numerosity training enhances the arithmetic performance of DD children by improving their visual form perception.     

Body Talk on Social Networking Sites,Body Surveillance,and Body Shame among Young Adults: The Roles of Self-Compassion and Gender

The present study examined whether body talk on social networking sites (SNSs) was positively associated with body surveillance and body shame and whether body surveillance would mediate the relationship between body talk on SNSs and body shame. We also tested whether the links from body talk on SNSs to body surveillance and body shame would be moderated by self-compassion. Furthermore, the moderating role of gender in the mediation model was examined. The model was tested with 194 female and 119 male Chinese university students who completed questionnaires regarding body talk on SNSs, body surveillance, body shame, and self-compassion. Results indicated that body talk on SNSs was positively related to body surveillance and body shame. The relationship between body talk on SNSs and body shame was mediated by body surveillance. Furthermore, self-compassion moderated the association between body talk on SNSs and body shame. No gender difference was found in the mediation model. Findings from the current study provide new insights into the development of objectified body consciousness among women, as well as among men, and highlight the potential value of promoting self-compassion in the prevention of body image concerns.

     

Does the mortality salience effect on worldview defence depend on the cultural orientation of Chinese people?

According to the terror management theory, people tend to favour their worldview and in-group members after being reminded of death (i.e., mortality salience [MS] effect). However, inconsistent findings of the MS effect were found among Chinese people. In the present study, we examined the MS effect with Chinese samples and tested whether the effect would depend on participants' cultural orientation and relational self-esteem. In Studies 1 (N = 227) and 2 (N = 221), we examined the roles of participants' cultural orientations and relational self-esteem in their evaluations on moral transgression and/or perceived regard from people around after being primed with mortality (vs. dental pain) salience. We obtained the interaction effects of mortality salience, cultural orientations, and relational self-esteem. The implications of these results are discussed in the context of Chinese culture.

Can genes modulate anchoring effect?

The anchoring effect is a well-known decision bias, referring that initial irrelevant number (anchor) can impact late estimation. Anchoring effect can be explained as people starting from the anchor and stopping incremental adjustment too early—in other words, jumping into the conclusion impulsively. High impulsivity is associated with AA genotype of rs806379. Therefore, we hypothesized that rs806379 polymorphism can exert an influence on the anchoring effect. The subjects completed an experimental task of anchoring effect and provided saliva for genotyping. As expected, we found that subjects with AA genotype of rs806379 demonstrated stronger anchoring effect. This is the first article that explores the anchoring effect from the gene perspective. Our finding suggests that nature plays a role in anchoring effect.

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。     

自杀大学生生活事件的心理解剖研究

该研究采用心理解剖方法对39例自杀大学生的生活事件进行分析.结果发现:自杀大学生在自杀前经历了较多且较为强烈的负性生活事件；导致大学生自杀的生活事件多元化但又相对集中；大多数自杀行为在生活事件发生后3个月内实施.因此,负性生活事件可作为大学生自杀预警的重要指标.     

Neural decoding of positive and negative self-knowledge

A prevalent explanation for the self-reference effect is that self-knowledge is represented by a set of specific brain regions, including anterior cingulate cortex (ACC), middle frontal gyrus (MFG), superior temporal gyrus (STG), precuneus, and inferior parietal lobule (IPL), which enables self-knowledge to be processed in priority than other-knowledge. However, the conventional univariate activation analysis adopted by previous studies could only detect the activation of separate brain regions. The current study mainly investigated the global neural patterns of self-knowledge (relative to other-knowledge) by the multivariate pattern analysis (MVPA). Results obtained in Experiments 1 and 2 were highly consistent, indicating that the core self-network (mainly the ACC) and salience network (mainly the insula) could distinguish self-knowledge from other-knowledge. Furthermore, the neural pattern of positive self-knowledge mainly included the ventral part of ACC, while the neural pattern of negative self-knowledge mainly included the ventral and dorsal parts of ACC and cognitive control network (dorsolateral prefrontal cortex: dlPFC). These findings suggest that the core self-network and salience network are specific to the neural process of self-knowledge. Moreover, both positive and negative self-knowledge are separately driven by different cognitive and neural characteristics.

     

人格分化假设:大学生样本的证据

基于智力差异的人格分化假设认为,高智力者比低智力者有更多可变的、更分化的人格。该研究在653名大学生样本中检验了这一假设,结果表明:(1)高IQ组比低IQ组倾向于获得更极端的人格分数,在大多数人格维度上,尤其是外倾性和开放性维度,高IQ组的人格结构更加分化。(2)除神经质与宜人性、外倾性与开放性的相关外,高IQ组在其他特质维度中都比低IQ组有更低的相关和更多的人格结构。(3)没有充分证据表明高IQ组比低IQ组在人格测量中有更高的信度。     

马克思分配公正思想的逻辑生成 ——基于《哥达纲领批判》视阈

马克思关于生产方式决定分配方式的历史唯物主义观点是认知和建构分配公正的逻辑前提。在共产主义社会第一阶段,要以创造价值的劳动为基本尺度实行分配,即按劳分配,虽然以劳动为尺度对社会总产品进行分配的原则超越了"按资分配",但按劳分配也是特殊公正论,仍然是形式公正,是初步的、非完全意义上的实质公正。分配的实质公正——按需分配,只有在共产主义社会高级阶段才能实现。
