恒河猴在繁殖笼内的等级结构

<正> 有关非人灵长类社群结构的问题,国外已多有研究。许多学者认为无论在野外,或是在捕后(笼养)条件下进行观察都发现只要有几只动物在一起,形成一个群,那末群内的个体之间必然形成等级关系,而这种等级关系是线性排列的。换句话说,如果一群有A、B、C、D、E五只动物的话,它们的等级关系就是这样排列的:A>B>C>D>E。     

5~6岁幼儿对不同文化背景卡通面孔再认的眼动研究

采用不同文化背景卡通面孔为刺激材料,探究中国幼儿对中国风、日本风与欧美风女性卡通面孔再认的差异及其眼动机制。结果显示：（1）卡通面孔再认正确率差异显著,日本风面孔具有记忆优势;女童对三种面孔再认正确率均显著高于男童;（2）卡通面孔特质中的夸张性对卡通面孔再认正确率的预测显著;（3）文化背景与性别因素显著影响平均注视时间、注视点个数、眼跳次数和幅度及瞳孔大小等总体眼动指标;（4）兴趣区数据显示：对日本风面孔的总注视时间和注视点个数最高;卡通面孔再认主要依赖于眼部、其次为鼻子;文化背景与兴趣区存在交互作用,在注视时间、注视点个数与首注视点指标上,提示幼儿更关注日本风的眼睛区域与欧美风的鼻子区域。综上,幼儿对不同文化背景卡通面孔的记忆和眼动加工存在差异,日本风卡通面孔的记忆优势可能基于其夸张性高的面孔特质,尤其在眼睛部位;行为学与眼动指标均提示女童对卡通面孔的再认具有优势。     

不同阅读水平儿童中央执行系统比较研究

本研究通过两部分实验探讨汉语发展性阅读障碍儿童与正常儿童中央执行系统的容量差异和这种差异的性质。通过比较匹配生理年龄的不同阅读水平儿童在自定步速和固定步速的复杂阅读广度测验中的成绩,发现发展性阅读障碍儿童在两种阅读广度测验中都表现出中央执行系统容量的缺陷,这种缺陷既不能用加工效率理论,也不能用资源分配理论来解释,而符合一般容量假设。因此,本研究支持发展性阅读障碍儿童存在实时加工和存储信息的一般容量缺陷。     

Servant leadership effectiveness: do religious atmosphere and housing price matter? social information-processing Perspective

Leadership effectiveness is a result of the interaction between leadership style and the social and organizational environment. We draw on social information-processing theory and analyze how the interaction between servant leadership and the social environment (i.e., religious atmosphere and housing price in one region) influences employee behavior. We likewise measure geographic-proximity-based religious atmosphere and housing price variables on the basis of 25 geographically disparate branches of a company, including a sample of 82 supervisors and 351 employees. Multilevel analyses reveal that the interaction between servant leadership and religious atmosphere has a positive effect on employee helping behavior but not for employee voice behavior. Conversely, the interaction between servant leadership and housing price has a positive effect on employee voice behavior, but does not have such effect on employee helping behavior. We also discuss the theoretical and practical implications on leadership research.

     

Vacancy-decomposition-induced lattice instability and its correlation with the kinetic stability limit of crystals

Vacancy decomposition kinetics in crystals at elevated temperatures is analysed. It is found that lattice instability is induced by a significantly enhanced vacancy decomposition at a critical temperature (T?*). The critical temperature coincides with the kinetic instability limit (kinetic limit of superheating) of crystals in a variety of metals determined from the homogeneous nucleation catastrophe model.     

虚拟时代的哲学

如果古典时代的哲人们穿越时空隧道来到我们这个充满虚拟实在的时代的话,想必他们会大吃一惊,以为来错了地方.对他们来说,我们这个时代肯定是个充满了莫名其妙事物的天方夜谭,是个让他们瞠目结舌的超现实世界.在我们这个世界中,众多网民的见面语早已经从"你吃饭了吗?"变成了"上网看到什么消息了?"、"魔兽了吗?"、"偷菜了吗?"等等.我们的通讯、信息获得、商品交易、交友恋爱、统计、企业管理甚至政治竞选,很大程度上已经通过网络进行.     

弗洛伊德论宗教和道德的关系

作为一个彻底的无神论者,弗洛伊德反对神道设教的主张。他认为,道德神圣化虽然能增强道德对一般民众的威慑力,从而对保护人类文明做出贡献,但将道德建立在宗教基础之上,却会使道德因失去现实基础而遭遇风险。另外,他强调宗教道德有着诸多消极的方面。     

采用词表法变式研究指向遗忘现象

在组内设计的词表法变式任务中,词表一的项目按语义或知觉特征分为遗忘项和记住项,中间指导语要求被试遗忘词表一某类项目的同时记住另一类项目,指向遗忘效应以词表一记住项与遗忘项的差异来反映。实验一中,词表一项目按语义性质分为记住项和遗忘项,结果显示:与控制组比较,标准词表法实验组词表一记忆受损显著,出现传统意义上的指向遗忘效应;变式实验组词表一记忆部分受损,与控制组差异接近.05显著水平;标准词表法实验组以及变式实验组词表二都没有表现出记忆获益;另外,变式实验组词表一记住项与遗忘项之间差异显著,反映出遗忘指导语效应。实验二发现:在变式任务中,指定被试遗忘词表一某种语义性质的项目,结果出现遗忘指导语效应;但是,在指定被试遗忘某种颜色项目时,结果没有出现遗忘指导语效应。变式任务结果比较好地支持提取抑制理论;同时也反映出,词表一记住项与遗忘项之间的区分度是影响变式情境下指向遗忘效应的重要因素。     

Dysfunctional body investment versus body dissatisfaction: Relations with well-being and controlled motivations for obesity treatment

In this study, we investigated the associations between body image and psychological well-being, exploring the mediating role of controlled regulation for entering obesity treatment. In addition, we analyzed whether investment body image was more strongly associated with controlled regulation (and subsequent well-being) compared to evaluative body image. These analyses were performed controlling for baseline BMI effects. Participants were 139 overweight women (age: 38.0 ± 6.7 year; BMI: 32.0 ± 4.1 kg/m²) entering treatment. Evaluative and investment body image, controlled regulation, and psychological well-being were assessed. Body image investment was positively associated with controlled regulation; evaluative body image was not. Controlled regulation was negatively associated with self-esteem and psychological functioning. Controlled regulation partially mediated the effects of body image investment on self-esteem, but did not mediate its effects on psychological functioning. Results suggest that dysfunctional body image investment might undermine well-being within overweight women, partly by increasing controlled regulation for entering obesity treatment. Discussion focuses on the importance of enhancing body image and autonomy during treatment to improve well-being and weight outcomes.     

8─11个月婴儿迂回行为发展特点与学习能力的研究
