The Third-Person Effects of Political Attack Ads in the 2004 U.S. Presidential Election

This study examines the indirect effects of extensive negative political attack ads in the 2004 presidential election from a third-person effects perspective. Results of a survey using a probability sample of 496 college students indicate that these students believe attack ads harm others more than themselves. Moreover, the respondents tended to perceive attack ads in traditional media to have a greater harmful effect on self and others than attack ads on the Internet. Contingent factors that account for the magnitude of third-person effects include social distance and knowledge. Further, exposure to attack ads was found to be the strongest predictor of perceived harms of such ads on self and others, but only perceived harm on others is a significant predictor of support for restrictions on attack ads. The study contributes to research on the third-person effect by testing perceived harms of attack ads on self and others separately on likelihood to support restrictions.     

音乐对工作记忆影响及机制的ERP研究

以肖邦音乐为刺激材料,采用数字n-back实验范式来研究肖邦音乐对工作记忆的影响方式,并通过运用事件相关电位技术(ERP技术),研究不同音乐条件下,正常人大脑皮层的脑电活动情况,进而探讨音乐对工作记忆影响的神经机制。30名被试参加了3种音乐条件(无音乐、先导音乐、背景音乐)下的n-back(n=1、2)工作记忆任务的行为实验,收集行为数据;14名被试参加了同样实验过程的ERP实验,记录脑电数据。行为结果发现音乐条件对工作记忆效果有显著影响,且先导音乐条件下记忆效果最好;脑电结果显示P3波幅随记忆负荷的增加呈下降趋势,高记忆负荷水平下,P3波幅随先导音乐、背景音乐、无音乐的顺序逐渐呈现下降趋势;源定位分析发现音乐对工作记忆的促进作用可能跟大脑顶叶被激活有关。     

A neural autopilot theory of habit: Evidence from consumer purchases and social media use

This article applies a two-process “neural autopilot” model to field data. The autopilot model hypothesizes that habitual choice occurs when the reward from a behavior has low numerical “doubt” (i.e., reward prediction errors are small). The model toggles between repeating a previous choice (habit) when doubt is low and making a goal-directed choice when doubt is high. The model has ingredients established in animal learning and cognitive neuroscience and is simple enough to make nonobvious predictions. In two empirical applications, we fit the model to field data on purchases of canned tuna and posting on the Chinese social media site Weibo. This style of modeling is called “structural” because there is a theoretical model of how different variables influence choices by agents (the “structure”), which tightly restricts how hidden variables lead to observed choices. There is empirical support for the model, more strongly for tuna purchases than for Weibo posting, relative to a baseline “reduced-form” model in which current choices are correlated with past choices without a mechanistic (structural) explanation. An interesting set of predictions can also be derived about how consumers react to different kinds of changes in prices and qualities of goods (this is called “counterfactual analysis”).     

选择反应作业中的反应组织

通过2-选择反应作业的两个反应复杂度不对称（不等）实验因素考察反应组织,发现在同一作业中无反应复杂度效应,而作业之间反应复杂度效应显著。这提示选择反应是选择已完成组织的反应,而不是实时地进行反应动作组织,进而引入动作模块的概念。即把反应组织视为选择动作模块过程。其实际意义是,在操作界面的优化设计中,要提高一组同时可选择操作R中的某一种操作Ri(R∈Ri|i=1,2,…,n）的绩效,其有效途径是应降低这一组操作R的平均复杂度;如果只降低Ri的复杂度,要提高其绩效收效甚微。     

文本结构和时间应激对网页阅读绩效的影响

探讨了文本结构和时间应激对网页阅读绩效的影响效应。采用 2× 3被试间设计 ,自变量为文本结构和阅读时间 ,因变量为找到相关信息的时间及途径的额外节点数。结果发现 ,主效应及交互作用的影响均十分显著。其中 ,当阅读时间为 10和 2 0min时 ,超文本阅读的绩效均显著低于线性文本 ,而在 30min时两者无显著差异 ;对超文本 ,三种阅读时间的效应存在显著差异 ,而对线性材料 ,阅读时间的效应无显著差异。结论 :时间应激对超文本阅读绩效的影响更为明显     

幼儿在集合比较中运用数数的实验研究

本研究中运用了两个实验探讨数数干预和测查条件对儿童在集合比较中运用数数的影响。干预对3岁儿童(M=3：9)没有影响。在平均年龄为4岁4个月时．干预组儿童比控制组儿童更倾向于用数数比较集合．自然组儿童也比传统组更倾向于用数数。许多4岁儿童在无干预时不用数数可能是因为,1)不知数数比视觉性比较更有效,或2)他们在集合比较中的数数极易受测查情景因素的影响。儿童在集合比较中的数数运用与他们的数数水平密切关联。     

公共行政伦理价值定位与规范体系

加强公共行政伦理建设,是加强政风建设、建设廉洁勤政务实高故政府、建设高素质公务员队伍的基本途径。因此,必须对公共行政伦理进行价值定位,借鉴国外公共行政伦理建设的经验,建构中国当代公共行政伦理的规范体系。     

问题解决中策略的变化：一项微观发生研究

以30名小学三年级儿童为被试,以一种特殊的方程问题为材料,采用微观发生法,先后进行了5次测查,收集了解题后的口语报告资料,从策略变化的路线、速率、广度、来源以及变化模式的多样性等方面详细探讨了问题解决策略的变化过程。结果发现,在面临新的问题时,被试缺乏相应知识和专门的解题策略,这时以使用多种常规策略以及错误策略为主;此后,当被试建构起对问题的正确表征时,就以使用正确策略为主,甚至发现了非常有技巧性和领域专门性的快捷策略,这时策略的数量明显减少;在面临难度较大的迁移题目时,快捷策略的使用率又降低,而更多借助于常规策略。可见,策略的获得是一个由错误到正确、由多种尝试到选择其一、由一般到专门的演化过程,这主要是一个学生自主建构的过程,当然也受到正式和非正式教育提供的知识的影响。值得说明的是,快捷策略的获得受到问题呈现模式的影响。总是呈现相同题目的单一模式有助于快捷策略的发现,而在混合训练中,插入不同性质的题目会干扰快捷策略的发现;但是,当面临迁移问题时,单一训练相比于混合训练的优势会消失。此外,正确使用常规策略是发现快捷策略的前提。     

A century of Chinese developmental psychology

At the turn of last century, psychology, including developmental psychology, was introduced into China. Since then, developmental psychology has always been one of the main branches of Chinese psychology. This paper reviews the progress of Chinese developmental psychology in the last century, with special emphasis on its development during the recent 20 years. The paper consists of three sections. The first is a historical review. The 100 years' history of Chinese developmental psychology has been divided into three phases: first half of the 20th century; the period between 1950s and 1970s after the foundation of the People's Republic of China; and the period from the end of the 1970s up to the present. The authors briefly describe the initiation of Chinese developmental psychology, highlighting the research and related work in the field during the three phases. The second section of the paper introduces the research conducted by Chinese developmental psychologists during the last two decades in the following areas: cognitive development, language development, social development and socialization, the study of gifted children, cross‐cultural studies of child development, the study of only children, and the psychology of ageing. This section is the focus of the paper, because in this period, developmental psychology in China has progressed steadily on a sustained course and entered an unprecedented thriving period along with the State opening‐up policy and structural reformation. The last section is an appraisal of the past and prospects for the future. Here, the authors comment on the characteristics and achievements of Chinese developmental psychology in the 20th century and discuss future directions for its further development in terms of research scope and depth, research methods, indigenization, and application.
