The Cognitive Social Network in Dreams: Transitivity,Assortativity, and Giant Component Proportion Are Monotonic

For five individuals, a social network was constructed from a series of his or her dreams. Three important network measures were calculated for each network: transitivity, assortativity, and giant component proportion. These were monotonically related; over the five networks as transitivity increased, assortativity increased and giant component proportion decreased. The relations indicate that characters appear in dreams systematically. Systematicity likely arises from the dreamer's memory of people and their relations, which is from the dreamer's cognitive social network. But the dream social network is not a copy of the cognitive social network. Waking life social networks tend to have positive assortativity; that is, people tend to be connected to others with similar connectivity. Instead, in our sample of dream social networks assortativity is more often negative or near 0, as in online social networks. We show that if characters appear via a random walk, negative assortativity can result, particularly if the random walk is biased as suggested by remote associations.     

Does Theory of Mind in Pre-kindergarten Predict the Ability to Think About a Reader’s Mind in Elementary School Compositions? A Longitudinal Study

A critical skill in emergent writing is the developing ability to take the perspective of different readers; however, the precursors of this skill have not yet been identified. In this longitudinal study, 105 children (90 after attrition) were tested at 3 time points: pre-kindergarten (3–4 years old, n = 105), kindergarten (5 years old, n = 97), and Grade 1 (6–7 years old, n = 90). Theory of mind (ToM) in pre-kindergarten significantly predicted children’s awareness of a reader’s epistemic state when they dictated letters in both kindergarten and Grade 1 even after controlling for language (Peabody Picture Vocabulary Task [PPVT]) and inhibitory control. In addition, ToM in pre-kindergarten remained a significant predictor of reader awareness in Grade 1 after further controlling for reader awareness in kindergarten. There was little relationship between higher-order ToM tasks in kindergarten and reader awareness, but higher-order ToM in Grade 1 concurrently predicted reader awareness. Receptive vocabulary (PPVT) was significantly related to reader awareness at all time points, longitudinally and concurrently. This study has both theoretical implications for the relationship between ToM and emergent literacy and practical implications for the early identification and remediation of children at risk for later writing difficulties.     

Revisiting “Upstream Public Engagement”: from a Habermasian Perspective

The idea of conducting “upstream public engagement,” using nanotechnology as a test case, has been subject to criticism for its lack of any link to the political system. Drawing on the theoretical tools provided by Habermas, this article seeks to explore such a “link”, focusing specifically on the capacity of civil society organizations (CSOs) to distil, raise and transmit societal concerns in an amplified form to the public spheres at the European Union (EU) level. Based on content analysis and semi-structured interviews with relevant actors, this article examines the evolution of CSO approaches towards nanotechnology over the past decade and investigates whether and how upstream public engagement could contribute to more vibrant public spheres and facilitate the formation of communicative power. The answer to these questions is twofold: on the one hand, moving public engagement “upstream” enables CSOs to be better informed and to become part of the debates more quickly. A “green alliance” is taking shape, which calls for more stringent regulation on nanomaterials. On the other hand, upstream public engagement has turned out to be unsuccessful in generating substantial and sustained interest. A number of CSOs have quit this field in frustration at the tokenistic engagement and out of fatigue after the intense lobbying battle for Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH).     

母亲积极教养与青少年亲社会行为：共情的中介作用与OXTR基因的调节作用

诸多研究显示母亲积极教养能够促进青少年亲社会行为的发展, 但是迄今对其内在作用机制尚不清楚。本研究基于“基因-环境-内表型-行为”模型, 采用问卷法和DNA分型技术, 对1082名青少年(初测年龄为12.32 ± 0.48岁, 50.3%女生)及其母亲进行为期2年的追踪研究, 考察共情在母亲积极教养与青少年亲社会行为间的中介作用, 以及OXTR基因rs53576多态性对该中介机制的调节作用。结果发现：(1)青少年认知共情(观点采择)在母亲积极教养和亲社会行为之间起中介作用, 而情绪共情(移情关心)的中介作用不显著; (2) OXTR基因对积极教养与亲社会行为间直接路径的调节作用不显著; (3) OXTR基因能够调节“母亲积极教养-认知共情-亲社会行为”中介机制的前半路径, 并且显现出一种超显性的基因效应。在携带GG和AA基因型的青少年中, 母亲积极教养显著正向预测认知共情, 进而增加了其亲社会行为, 而在携带AG杂合子基因型的青少年中, 这一中介效应则不显著。研究结果有助于从催产素受体基因多态性、共情能力和家庭教养等方面阐明青少年亲社会行为的发生机制及个体差异。     

知觉模糊度影响学习的延迟效应

基于迁移适当加工理论,采用连续识别任务范式,通过操纵字词和图片的模糊度来考察知觉模糊非流畅的延迟效应。结果发现：（1）模糊不流畅的材料学习判断值更低;（2） 知觉模糊程度对即时的再认成绩没有影响,但在延迟再认测试中流畅性较低的模糊材料成绩更好。该结果表明实验操纵方式所引发的编码过程和记忆测试所需的检索过程性质上相匹配,而且延迟测试时,知觉非流畅可以促进学习,说明该效应存在边界。     

Mind-reading in strategic interaction: The impact of perceived similarity on projection and stereotyping

In social dilemmas, negotiations, and other forms of strategic interaction, mind-reading—intuiting another party’s preferences and intentions—has an important impact on an actor’s own behavior. In this paper, we present a model of how perceivers shift between social projection (using one’s own mental states to intuit a counterpart’s mental states) and stereotyping (using general assumptions about a group to intuit a counterpart’s mental states). Study 1 extends prior work on perceptual dilemmas in arms races, examining Americans’ perceptions of Chinese attitudes toward military escalation. Study 2 adapts a prisoner’s dilemma, pairing participants with outgroup targets. Study 3 employs an ultimatum game, asking male and female participants to make judgments about opposite sex partners. Study 4 manipulates perceived similarity as well as counterpart stereotype in a principal–agent context. Across the studies, we find evidence for our central prediction: higher levels of perceived similarity are associated with increased projection and reduced stereotyping.     

资本主义研究在马克思社会形态理论中的地位

<正>社会形态理论是马克思主义的研究者最为重视的马克思历史理论之一,甚至被看作历史唯物主义的核心部分,但同时也是引起最多争议和质疑的部分。然而,无论是关于社会形态演进序列之"五形态"与"三形态"的争论,还是关于社会形态的依次演进是否具有历史必然性的争论,抑或关于     

青年情绪智力与主观幸福感的关系

以444名青年为研究对象,采用Schutte编制的《情绪智力量表》、艾森克人格问卷和Diener等人编制的《国际大学调查》为研究工具,调查青年各群体的主观幸福感水平,并对情绪智力和主观幸福感的关系进行了研究。结果发现,青年不同群体之间存在显著的主观幸福感差异,本科生群体的主观幸福感水平最高;在控制了人口学变量和人格变量之后,情绪智力能独立预测主观幸福感各维度的变异。

Surface effect on the screw dislocation mobility over the Peierls barrier

The effect of the image force on the Peierls stress (τ _p ) of a screw dislocation below a free surface is studied via a self-consistent semidiscrete variational Peierls–Nabarro model. The consequence of reduction in elastic energy and increase in stacking fault energy by the presence of the free surface is found to additively increase the Peierls stress (τ _p ). This model gives a physical interpretation of the same tend observed in a recent molecular dynamic study, while previous continuum analysis predicted the opposite.
