人格特质对微信用户朋友圈点赞行为动机影响的研究

移动互联网时代,微信的出现颠覆了人们的沟通方式,而点赞作为网络人际之间的互动更是呈现了用户的个人调节与社会认同。本研究采用问卷的方法,对368名微信用户的点赞动机与人格特质的关系进行调查。结果发现:(1)点赞行为有着不同的动机背景,这其中主要是自我认同和社会认同动机在起推动作用。(2)这其中不同动机的人又有着不同的人格特质,具体而言,严谨性与外向性影响自我认同,而宜人性与开放性影响社交认同。     

Statistical regularities guide the spatial scale of attention

Visual scenes contain information on both a local scale (e.g., a tree) and a global scale (e.g., a forest). The question of whether the visual system prioritizes local or global elements has been debated for over a century. Given that visual scenes often contain distinct individual objects, here we examine how regularities between individual objects prioritize local or global processing. Participants viewed Navon-like figures consisting of small local objects making up a global object, and were asked to identify either the shape of the local objects or the shape of the global object, as fast and accurately as possible. Unbeknown to the participants, local regularities (i.e., triplets) or global regularities (i.e., quadruples) were embedded among the objects. We found that the identification of the local shape was faster when individual objects reliably co-occurred immediately next to each other as triplets (local regularities, Experiment 1). This result suggested that local regularities draw attention to the local scale. Moreover, the identification of the global shape was faster when objects co-occurred at the global scale as quadruples (global regularities, Experiment 2). This result suggested that global regularities draw attention to the global scale. No participant was explicitly aware of the regularities in the experiments. The results suggest that statistical regularities can determine whether attention is directed to the individual objects or to the entire scene. The findings provide evidence that regularities guide the spatial scale of attention in the absence of explicit awareness.     

Predictors of Stress Generation in Adolescents in Mainland China

The current longitudinal study examined whether the personality vulnerabilities of self-criticism and dependency prospectively predicted stress generation in Chinese adolescents. Participants included 1,116 adolescents (588 girls and 528 boys), aged 15 to 18 years from rural, urban and ultra-urban mainland China. Participants completed self-report measures of personality, depressive and anxious symptoms and participated in a clinical interview assessing lifetime history of depression. The occurrence of negative life events was measured using a contextual-threat interview every 6-months for a total period of 18-months. Logistic regression analyses showed that after controlling for past depressive episodes and current depressive and anxious symptoms, self-criticism was prospectively associated with the occurrence of interpersonal stress generation, but not noninterpersonal stress generation. Dependency also predicted interpersonal stress generation, although only in girls and not boys. In line with previous Western findings, girls reported more interpersonal stress generation. Analyses across 3 levels of urbanization revealed several significant differences including higher reported interpersonal stress generation in urban girls than urban boys and overall higher levels of negative life events in ultra-urban youth. In sum, findings from the current study suggest that the stress generation process may be generalizable to Chinese youth.     

组织支持感对组织认同的影响:内部人身份感知和自尊的中介作用

检验了内部人身份感知(PIS)和基于组织的自尊(OBSE)在组织支持感(POS)对组织认同的影响过程中的角色和地位。采用多样本结构方程建模的方法,通过对中国2家企业的员工的问卷调查所获取的452份有效数据进行分析,结果表明:(1)POS对PIS和OBSE有直接的显著影响;(2)同时借助于PIS和OBSE的中介作用对组织认同产生间接的影响。     

迪昂问题及其解决

迪昂问题是当代科学哲学争论的主题之一。波普尔、拉卡托斯和库恩都曾经对此问题给予不同的对待或解决。本文对此背景给以扼要的介绍,然后着重介绍和评价一种新的解决方案——基于贝叶斯方法的解决。相比之下,后一方案较为令人满意。     

意识心理学研究的复兴与发展特点

当前西方心理学界出现了一场前所未有的意识研究的“文艺复兴”运动．取得了许多重要的实质性研究成果。在研究范式和技术方法上已有了,明显的突破;在基础理论方面．意识概念的操作性定义日益明确,对于意识实质的理解和理论模型的解释也出现了不断递进的趋势。     

中国消费者价格容忍度的特点

运用多维线性模型,对我国消费者对不同产品价格涨落的容忍态度进行了研究。研究对象为26384名购买过各类产品的消费者。结果表明：（1）消费者对不同产品的价格容忍度不同,对日用消费品的价格容忍度较高,对耐用消费品的价格容忍度相对较低;（2）消费者的年龄和受教育程度对价格容忍度有负向的影响,消费者的年龄和受教育程度越高,对产品的价格容忍度越低;（3）男性消费者的价格容忍度高于女性消费者,女性消费者对价格较为敏感。     

我国一大型考试等值的铆题参数漂移检验

设置铆题来链接不同测验形式是一种常用的等值设计。但受到曝光等因素影响,铆题功能在不同施测时间会发生改变。本研究采用MH检验和logistic回归考察我国一大型考试等值的铆题质量,结果发现,有22个铆题发生参数漂移,铆题的难度参数和区分度参数可能发生漂移;这些铆题中大部分在二次使用时无法通过模型拟合检验;若不删除参数发生漂移的铆题导致较大的系统等值误差,应将铆题参数漂移检验作为等值中的一步必要工作。     

当代功利主义哲学

虽然功利主义自20世纪70年代以来失去了一统天下的地位,但是它目前在当代道德哲学和政治哲学中仍然是一支重要力量。按照其论证的逻辑,我们可以把功利主义分为三种,即行为功利主义、规则功利主义以及双层功利主义,其中后两者是为克服前者的困难而产生出来的,同时它们也产生出了新的困难。然而,无论在理论层面还是政策层面,功利主义在当代西方社会都占有重要的地位。     

智力和元认知技能在发现学习中的作用:任务复杂性的影响

采用自编的计算机模拟发现学习任务,以49名大学生为被试,探讨了在简单和复杂发现学习任务中,智力、元认知技能和学习成绩三者之间的关系。结果发现:在简单任务中,三者关系基本符合混合模型;进行过多的元认知活动,并不能提高学习效果。在复杂任务中,智力对学习成绩起主要预测作用。随着任务复杂性的增加,智力对学习的影响也随之变化,符合难度阈限理论的假设。任务复杂性不同时,智力、元认知技能和发现学习成绩之间的关系也不同,在一定程度上验证了难度阈限扩展理论。
