低出生体重与代谢综合征

低出生体重是发生成年期代谢综合征的高危因素。“代谢程序化”与“营养程序化”概念的提出对人们从多层面认识该现象的内在机制有重要指导作用。随着对发生机制研究的深入,人们终将找到预防低出生体重发生成年期代谢综合征的早期干预措施。     

气质和儿童同伴交往类型关系的研究

该文采用问卷法和社会测量法相结合的方法,以班级为单位对484名3~9岁儿童的气质和同伴关系类型的关系进行研究。结果表明:3~9岁儿童同伴关系类型已形成分化,其中被忽视儿童和被拒绝儿童所占总体样本的比例分别为16.9%和9.6%,比例较高值得重视。儿童气质对同伴交往类型的形成影响很大,四种同伴关系交往类型在气质各维度上方差检验都达到了差异显著,有着明显不同的气质特点。     

中央凹加工负荷与副中央凹信息在汉语阅读眼跳目标选择中的作用

研究探讨汉语读者选择眼跳目标时, 中央凹注视词的加工负荷是否影响副中央凹获取信息量, 进而调节随后的眼跳长度。采用眼动追踪技术, 操纵了中央凹注视词的词频(高频、低频)和副中央凹词的笔画数(多笔画、少笔画)。结果发现：从中央凹词到副中央凹少笔画词的眼跳长度显著地长于到多笔画词的, 且这种笔画数效应并不受中央凹加工负荷的调节; 从高频中央凹词到副中央凹词的眼跳长度显著地长于低频词的。在本实验条件下结果提示：中央凹加工负荷在眼跳目标选择中的作用不是通过调节副中央凹获取信息量的多少来实现的。     

Cultural worldviews and climate change: A view from China

We investigated the association between cultural worldviews and climate change risk perceptions, support for climate friendly policies and climate change mitigation behaviours in a large Chinese sample. Items from Dake's cultural theory scales and Kahan's cultural cognition scale were presented to a Qualtrics online panel consisting of 515 Mandarin‐speaking residents of Beijing. A series of factor analyses revealed that the combined item sets were best represented by four‐dimensions: hierarchism, individualism, egalitarianism and fatalism. Mediation analysis revealed that respondents with egalitarian and non‐fatalist worldviews perceived greater risk associated with climate change, which in turn predicted greater support for policies to manage climate change and increased mitigation behaviour. In addition, respondents who scored high on individualism were less likely to support climate change policies, but this effect was not mediated by risk perceptions. Overall, our results suggest cultural worldviews may influence policy support both directly and indirectly through risk perceptions.     

Maximus the Confessor and the Problem of Participation

In defining the theological problem of participation as the question of how created beings, namely human beings, can participate (μ?θεξι?) in the transcendent Uncreated God towards deification (θ?ωσι?) without a pantheistic blurring of essences, this article examines the Christologically intuitive way in which Maximus the Confessor (580–662) would have responded. Specifically, Maximus’ Cyrilline Chalcednonianism, featuring an unconfused perichoretic union between Christ's two natures in his hypostatic union, serves directly as an apologetic and hermeneutic for humanity's and creation's participation in God. In addition, taking into account the scholarly debate over Maximus’ understanding of the relationship between the Logos and the logoi, it is argued that this indirectly provides a second Christological way forward to resolve the problem at hand, particularly when the two types of logoi (that ‘of being’ and that ‘of virtue’) are correctly distinguished. Insofar as the Logos and the logoi, not to mention the notions of participation and deification, were viewed by Maximus through his Cyrilline Chalcedonian lens, his Cyrilline Chalcednonian Christology was ultimately his answer to the theological problem of participation.     

The Training Effect of Working Memory Based on Central Executive System Intervention in Older Adults: A Randomized Controlled Study

This article aims to investigate the training effect of working memory in older adults. A total of 43 older adults ranging in age from 75 to 95 were recruited to participate in the study. A battery of tests regarding central executive function, working memory, and primary mental ability were administered in the pretest phase. A total of 22 of the older participants were randomly selected as the intervention group. Thirteen days after the pretest, the same tests were administered to all of the participants. The results showed that (1) the differences in the pretest and posttest gains in the task-switching tests were not significant between the intervention group and the control group; (2) the performance of the intervention group on the operation working memory span test and the graphical reasoning test showed a significant improvement after the intervention compared with the control group who did not receive the intervention. We can conclude that the working memory of old adults may be improved by an intervention targeting the central executive system. However, this possibility needs further investigation.

结构方程模型检验：拟合指数与卡方准则

讨论了Hu和Bentler（1998,1999）推荐的检验结构方程模型的7个拟合指数准则,对这7个指数的历史、特点和表现做了比较详细的述评。指出了他们基于这7个指数的单指数准则和2-指数准则的不足之处。提出了超低显著性水平下的卡方准则,并部分重复他们的模拟例子,将卡方准则与这7个指数准则比较,结果说明新的卡方准则优于其中的6个,与另一个相当。最后简要说明了应当如何检视拟合指数进行模型检验和模型比较。     

贫困大学生元刻板印象威胁对群际关系的影响:群际焦虑的中介和自尊的调节作用

元刻板印象威胁是指消极元刻板印象所导致的群体成员的一种社会心理困境和认知不平衡状态,会诱发压力和害怕体验,进而损害其行为表现。基于群际焦虑模型,本研究拟考查元刻板印象、群际焦虑、自尊等因素对群际关系的影响,具体为贫困大学生消极元刻板印象对群际关系的影响及群际焦虑的中介作用、自尊的调节作用。研究以江苏省徐州市某高校的158名贫困大学生为被试,通过操控指导语的方式将其随机分为威胁组（消极元刻板印象激活组）和无威胁组（元刻板印象未激活组）。结果如下：（1）威胁组被试的群际焦虑水平显著高于无威胁组,群际关系水平显著低于无威胁组;（2）群际焦虑在元刻板印象威胁与群际关系间起中介作用,自尊在前半路径（元刻板印象和群际焦虑间）和后半路径（群际焦虑与群际关系间）均起调节作用。结论：激活贫困大学生消极元刻板印象会对群际关系产生威胁效应。     

幼儿在联合行动中共同表征能力的发展

为探究幼儿联合行动共同表征能力的发展,实验1通过比较186名3~5岁幼儿在相同任务和不同任务的表现,发现4岁和5岁幼儿在不同任务中的表现比相同任务差;实验2进一步验证幼儿在不同任务中较差的表现源于对自我和同伴的共同表征。结论：3岁幼儿无法在联合任务中同时表征自我和同伴,没有表现出明显的共同表征能力,4岁以上幼儿开始具备稳定的共同表征能力,能够在联合任务中同时表征自己和同伴,由此对自己的行为表现造成干扰。
