新闻道德缺失的诱因分析

在信息化时代和政治民主化的进程中,媒体作为与国家的行政、立法、司法并列的"第四种权力",对社会成员思想和行为的影响力,已成为不争的事实,由之也凸显出对新闻道德缺失诱因分析的重要性.新闻道德的缺失有六大诱因:新闻媒体生存的经济价值与社会功能的思想价值的矛盾性、媒体的自由性与责任性的制度缺位、人性的低俗性与新闻媒体的媚俗性、新闻媒体利益寻租的便档、新闻的时效性与真实性的矛盾以及新闻媒体的舆论监督与平衡性的矛盾.     

由《366天诞生星》说到模特的“洋属相”——是普及科学知识，还是宣扬星座迷信

同古代神话故事密不可分的西方占星术,正是适应众生对神秘星空和神话世界的诸多遐想以及对改变自身处境的渴望,比天文知识更广地流传开来。这种方术是把位于太阳黄道上的12个星座与人的生辰乃至性格和命运拉扯在一起,由之推测未来的“运势”会是如何如何。西方占星术士们玩的这一套,乍看起来有些类似中国古代星象家说的     

Attitudes toward computers: a new attitudinal dimension.

The present study examined the reliability and the construct validity of a questionnaire designed to measure the attitudes toward computers in everyday life. A total of 2,050 participants responded to the questionnaire. Confirmatory factor analysis suggests that attitudes toward computers are composed of three dimensions: sense of benefit, sense of dependence, and sense of harm.     

Chinese Internet addiction inventory: developing a measure of problematic Internet use for Chinese college students.

The current study developed a psychometrically sound multidimensional measure of Internet addiction: the Chinese Internet Addiction Inventory (CIAI). Data were collected from 1,029 Chinese undergraduate students from 14 universities and colleges. The initial sample was split randomly into two samples (N1=516; N2=513). An exploratory factor analysis (EFA) and a confirmatory factor analysis (CFA) were conducted on the two samples respectively. Findings from the EFA suggest that this measure assesses three dimensions of Internet addiction: conflicts, mood modification, and dependence. Items in each dimension showed high internal consistency and acceptable test-retest reliability. Findings from the CFA further confirmed the three-factor measurement structure of CIAI. Test of criterion-related validity also showed good abilities for all three CIAI subscales to discriminate between an Internet addictive group and non-Internet addictive group. The theoretical and clinical implications of CIAI and its limitations are discussed.     

What is in a word? No versus Yes differentially engage the lateral orbitofrontal cortex

The words "No" and "Yes" are involved in conditioning to prohibit or encourage behavior, respectively. The authors, therefore, hypothesized that these words would be attributed to endogenous valence, activating neuronal circuits involved with valence and emotional control. Functional MRI (fMRI) at 4 Tesla was used to record regional brain activity while participants were exposed to emphatic vocalizations of the words. Results showed that No and Yes were associated with opposite brain-behavior responses; while No was negatively valenced, produced slower response times, and evoked a negative signal in the right lateral orbitofrontal cortex (OFC), Yes was positively valenced, produced faster response times, and evoked a positive signal in a contiguous region of the OFC. Attribution of negative valence to No and trait anger control were associated with increased responsivity of the OFC to No. Inasmuch as sensitivity to the prohibitive command No develops during childhood through interaction with primary caregivers as the first social objects, our findings may implicate the lateral OFC in the neurobiology of emotion regulation and subsequent social development.     

调节性匹配理论述评

在决策、动机领域,Higgins（2000）提出了一种新的理论——调节性匹配理论。所谓调节性匹配（regulatoryfit）,指的是个体的自我调节定向与其行为策略之间的匹配。该理论认为,调节性匹配能增强个体在目标追求过程中的动机强度、主观评价和情绪体验,从而对个体的行为决策产生重要影响。文章围绕调节性匹配的概念、产生、效应及应用价值等问题对相关研究进行综述,并在此基础上提出了现有研究存在的问题及未来的研究方向     

自尊与自我效能关系的辨析

作为自我结构中的核心成分,自尊与自我效能既相互关联又彼此区分。从概念上看,自尊是“做人”的自我评价,自我效能是“做事”的自我评价。从测量上看,自尊注重测量整体结构,自我效能强调测量领域关联的特殊结构。从功能上看,自尊旨在调节消极性评价反馈和终极性心理健康,自我效能则具有动力性功能。从影响因素上看,自尊决定于早期的成长经历以及后来的补偿性经验;而自我效能决定于个人近期直接或间接的成败经验和个人身心状态等因素     

儿童对道义情景中的心理状态的推理

该文回顾了儿童对道义情景中心理状态推理的研究,包括儿童对行为者愿望、信念和情绪的推理以及对权威愿望的推理研究。总体来讲,道义规则的引入使得儿童过分根据道义规则来对行为者的行为和心理状态进行推理,但是不同的研究还存在诸多矛盾之处,这可能与以往的研究中所使用的道义规则属于不同的领域（如道德、习俗及防范等领域）以及实验任务（如行为预测和奖惩判断等）的差异有关。最后该文提出另外两个可能的影响因素：道义规则的形式和儿童的视角采择能力     

计算机辅助教学对英语阅读能力的影响

通过回顾与总结CAI英语阅读教学程序由普适化向具体阅读技能转化的发展历程,总结了英语阅读中最重要的能力、技能和主要应解决的问题,阐述了CAI程序对于阅读教学的有效性研究成果:发现相关的CAI程序有五大范畴。最后就教学语言、课程设计、教师对CAI程序的运用等问题进行了探讨与展望。     

主观概率判断中次可加性的三因素实验研究

采用三因素完全随机实验探究主观概率判断是否满足次可加性规律,结果表明:(1)分解方式、分解数量和分解事例的典型性等三个因素对主观概率判断均有显著的影响。(2)次可加性不是一种普遍现象,主观概率判断中也会出现可加性和超可加性:把事件隐分为非典型事例时会出现超可加性,把事件隐分为典型或者典型加非典型性的事例时会出现可加性,而把事件显分时会一致出现次可加性。
