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。     

儿童期虐待与青少年网络欺负行为的关系：自尊的中介作用和友谊质量的调节作用

本研究采用问卷法对2407名青少年进行调查,探究儿童期虐待对青少年网络欺负行为的影响,以及自尊的中介作用和友谊质量的调节作用。结果表明：（1）儿童期虐待显著正向预测青少年网络欺负行为。（2）自尊在儿童期虐待与青少年网络欺负行为之间起部分中介作用。（3）儿童期虐待对青少年网络欺负行为的间接效应的前半段路径受到友谊质量的调节。友谊质量高、低水平下儿童期虐待对自尊的预测作用均显著,但友谊质量较高的青少年群体中儿童期虐待对自尊的预测作用更强。     

同伴特点如何影响人们的合作与冲突行为?

人类的生存繁衍依赖于人们之间的相互合作,合作与冲突行为的研究近年来成为心理学的研究热点。本研究通过实验程序操纵Chicken Game中博弈同伴的特点,考察个体在社会困境中面对不同特点同伴时的合作行为。结果发现：(1)同伴道义论组和功利论组总和解率没有显著差异,同伴竞争组和合作组的总和解率也没有显著差异。(2)在与道义论以及合作型的同伴互动时,个体的行为没有明显受到上次博弈反馈的影响。(3)当同伴为功利论时,相比于上次博弈个体选择和解而同伴选择进攻,双方都选择和解时个体在当前博弈中更倾向于和解;(4)在同伴竞争组中,相比于上次博弈个体选择进攻而同伴选择和解,双方都选择和解时被试在当前博弈中会更倾向于和解。实验结果表明个体在博弈任务中会受到同伴特点的影响,并且同伴在博弈中的行为特点的影响更为显著。本研究从同伴特点来考察个体的合作行为,揭示了影响个体博弈行为的一种因素。     

北朝临淄崔氏家族史新证

本文比照文献资料,对北朝临淄崔氏家族墓志所载崔鸿八世祖崔岳仕宦情况进行了考证,指出墓志所载崔岳“晋司徒”属于伪托。实际情况是:西晋时崔岳为朝鲜令,庇护匈奴刘曜而被追赠为前赵“大司徒”,由于十六国北朝时期匈奴与汉民族矛盾尖锐,在当时正统观念支配下,崔氏墓志及《十六国春秋》无不避讳此事。     

《管子》"人与天调"的生态观

《管子·水地》等篇章,阐述了人类应合理地使用和保护自然资源;以遵循自然规律为准则,建立人与环境良性互动的常态,它们忠实地记载了管仲及其学派在倡导农业生产中所表现出的环境与生存发展的生态平衡思想。     

A multi-objective mathematical programming problem with fuzzy relation constraints

In this study we discuss the problem of multi-objective mathematical programming with constraints defined by ‘max-min’ composite fuzzy relation equations. Since the feasible region is normally non-convex, the properties of the efficient points of a non-convex feasible region under multi-objectives are investigated and illustrated by examples. The necessary and sufficient conditions are proposed and proved. To facilitate decisions, a procedure that transforms these efficient points of an interval-valued decision space into a constant-valued decision space is proposed when the level of confidence is given by a decision maker. Then the transformed problem becomes a multi-attribute decision problem that can be evaluated by Yager's method to find the optimal alternative.     

春秋齐国军事体制对我国预备役部队建设之启示

中国古代有作为的君王与将相都十分重视军队包括后备力量建设。春秋五霸之首齐桓公在贤相管仲的辅佐下改革内政,建立国鄙制,“作内政而寄军令”,在国的行政单位基础上建立起三军编制,推行军政合一,寓兵于民。行政官员平时处理政事;战时则带领精兵作战。由于士卒平时居住在一起,彼此熟悉,且福祸相依,因而战时配合默契,生死与共,具有极强的战斗力,为齐建立霸业奠定了基础。春秋齐国军事体制的成功实践,对于今天现代预备役部队建设,仍具有启示意义。     

Effect of Acute Psychological Stress on Motion-in-Depth Perception: An Event-Related Potential Study

The present study explored the intrinsic event-related potential (ERP) features of the effects of acute psychological stress on the processing of motion-in-depth perception using a dual-task paradigm. After a mental arithmetic task was used to induce acute psychological stress, a collision task was used to evaluate motion-in-depth perception. The error value and average amplitude of late slow waves (SW) were significantly larger for the earlier colliding spheres’ than for the later colliding spheres. The P1 peak latency in the left occipital region was significantly shorter than that of the right occipital region in the motion-in-depth perception task. Compared to the control condition, the estimated value of residual time-to-collision and error value were significantly reduced, and the N1 peak amplitude and the SW averaged amplitude were significantly increased in the stress condition. Longer motion-in-depth time improved discrimination accuracy and decreased the investment of cognitive resources. Acute psychological stress increased behavioral performance and enhanced attention resources on the motion-in-depth perception task together with greater investment of cognitive resources.     

权力感对炫耀性亲社会行为的影响

基于高成本价值信号理论, 本文探究了权力感对炫耀性亲社会行为的影响。5个实验的结果表明：权力感促使个体更愿意从事炫耀性亲社会行为, 高(vs. 低)权力感个体更倾向购买炫耀性亲社会产品, 更愿意进行炫耀性捐赠且捐赠金额较高, 也更愿意参与炫耀性善行, 其机制在于高权力感者具有较高的自我矫饰动机。本文对理解权力感对个体行为的影响、丰富权力感与亲社会行为的研究文献有理论贡献, 对有效引导高权力感者从事亲社会行为具有实践价值。
