原型表征对创造性问题解决过程中的启发效应的影响

以32个科学发明创造问题为实验材料, 采用“学习8个原型-测试8个问题”的两阶段实验范式, 通过操纵原型学习条件(是否有标识或插图)考察了原型的知识表征对创造性问题解决的启发效应的影响, 结果发现：1)标识对原型的激活率在无插图水平上有显著影响, 有标识比无标识原型的激活率更高, 在有插图水平上无显著影响; 插图对原型的激活率有显著影响, 有插图比无插图原型的激活率更高。2)标识和插图都对问题解决的正确率有显著影响, 有标识比无标识正确率更高, 有插图比无插图正确率更高。3)标识和插图在原型激活率和问题解决正确率上都存在显著交互作用, 反映出原型启发的思维过程是复杂的, 表现出灵活性、经济性的特点。     

自我相关信息的加工优势：来自网名识别的证据

以网名为材料, 通过三项视觉搜索实验考察了与自我相关的网络信息可能存在的加工优势。结果发现, 自己的网名在作为靶刺激时可以更快且更准确地被探测出来; 而在作为干扰刺激时, 其对于靶刺激却并未表现出比对照刺激更强的抑制作用。在与真实人名进行的直接比较中, 自己的网名与真实人名的加工成绩未出现显著差异, 且都好于作为对照的名人名字。这些结果证明了与自我相关的网络信息具有和物理世界中的自我信息相似的加工优势, 且与以真实人名为材料的多项实验结果完全一致, 从而表明自己的网名与真实人名可能具有相同的加工机制。     

声旁语音信息对形声字加工的影响——来自眼动研究的证据

与拼音文字不同, 汉字是形义结合更紧密的文字, 因此语音信息在语义通达中的作用一直是汉语加工研究中存在争议的问题。形声字作为汉字的主体(80%), 其声旁在一定程度上提供了字的语音信息, 本文通过两项眼动研究考察了左右结构和上下结构形声字的声旁语音信息对形声字加工的影响。结果发现, 当声旁在右或声旁在下时, 省前与略后条件没有显著差异, 甚至出现差异的逆转, 也就是说当略后的笔画中包含声旁时, 亚词汇层面的声旁语音信息会影响到“笔画顺序效应”, 实验结果说明声旁的语音信息对形声字的加工起到重要作用。     

反馈对知觉类别学习的影响及其认知神经生理机制

知觉类别学习是一种人类对知觉刺激进行分类、习得类别的过程, 反馈是进行知觉类别学习不可或缺的重要部分。研究者通过操纵反馈的不同特征, 如反馈延迟(即时、延迟)、反馈性质(积极、消极)、反馈类型(丰富、简单)等, 对反馈如何影响知觉类别学习进行了广泛的研究, 并试图从神经生理学方面给出合理的解释。但是目前反馈对知觉类别学习影响的研究还存在许多不足, 特别在反馈延迟时间的细化、延迟反馈时间临界点、无关因素掩蔽、反馈试次等影响方面的研究较少涉及, 现有的反馈机制尚需进一步研究。     

害羞者对模糊情境信息的解释偏向

以模糊情境句子和形容词为刺激材料,分别采用文本材料范式和改编的词汇情境联接范式,对害羞者的延时解释和即时解释偏向特点进行探讨。结果发现：害羞者对模糊情境信息不仅缺乏积极的即时解释偏向特点,而且也缺乏积极的延时解释偏向特点;害羞者未表现出消极的即时和延时解释偏向特点。研究表明害羞者可能是社交焦虑的前期阶段,对害羞者的干预可以通过引导其积极的解释偏向的方式来实现。     

风险偏好、信息完整性对职业决策信息加工的影响

本研究旨在探讨个体风险偏好如何影响信息加工过程;同时呈现信息的完整性是否影响个体信息加工过程。以31名正在求职的大学生为被试,探讨了他们在信息板上进行职业决策的信息加工过程。结果显示：(1) 低风险偏好者比高风险偏好者更关注与概率相关的线索;(2) 当信息不完整时,个体在决策中增加了对概率相关线索的关注;(3) 信息完整性对个体决策信息加工过程并未产生显著的影响。     

Slavoj Žižek and the Real Subject of Politics

Slavoj ?i?ek's refusal to sketch an alternative to the global liberal-capitalist order, combined with his claim that there is an urgent need for a repolitization of, most of all, the economy, raises the question of the possibility of radical political thought and action. Considering fundamentalisms and politically correct multiculturalism not as oppositional, but as correlative to the “depolitization” of post-modern societies, ?i?ek invokes the emancipatory legacy of Europe in an attempt to reinvent Marxism in a way similar to what Lenin, thrown into an open situation, had to do in 1917 between the revolutions. A single question confronts political philosophy today: is liberal-capitalist democracy the ultimate horizon of our political practice, or is it possible to open up the space for another political articulation? The key to a repolitization is to identify with the “symptom” of the existing global order's false claim to Universality, with the excluded “part of no part” who politicizes it's predicament by claiming to stand for the real universal. In order not to discard political struggle as “unrealistic”, today's cynical “realist” consensus must be broken. Taking things as they “really are” has become the dominant ideological mode that keeps people from thinking about alternatives. The remedy is to show that things never are “really” as they are.

     

Shared knowledge and subgroup influence during decision‐making discussions

It was predicted that preference factions within decision‐making groups would have greater influence to the extent that faction‐member preferences are based on a common pool of decision‐relevant information. Such factions are said to exhibit high informational commonality (IC). Four‐person groups decided how much money to invest in each of two pharmaceutical companies developing new cholesterol‐lowering drugs. Prior to discussion, information about these companies and drugs was distributed among members such that two would initially prefer investing in one company and two would initially prefer investing in the other company. Further, whereas half of the information held by members of one preference faction was held in common between them (high IC), almost none of the information held by those in the other faction was held in common between them (low IC). It was found that groups invested more money in a given company when that company was initially preferred by their high‐IC faction. Additionally, high‐IC factions exerted greater influence on members' private allocation preferences. These effects appear to have been due to the ability of members in the high‐IC factions to work together in a more coordinated manner to argue their position.

注意受情绪信息影响的实验范式

研究显示情绪信息对注意会产生特殊的影响,主要表现为个体特别是某些患有情绪障碍的个体对情绪信息存在注意偏向或注意增强现象。该文围绕该问题,主要介绍情绪Stroop实验、点探测实验、线索提示实验、情绪条件反射实验以及快速序列视觉呈现实验等多个实验范式的研究方法和结果,并分析今后的发展趋势。     

自我与记忆

记忆的选择性或偏向性也许是稳定的人格特质——自尊的函数。一些研究者在个人记忆的研究范型及其理论模型的基础上．提出了针对自我概念的解决不一致——负向模型和忽视不一致——负向模型,以及针对双维整体自尊的心境一致性模型和相关模型。相应的实验研究结果支持忽视模型或相关模型,表明记忆的选择性也许发生的编码阶段。作者最后提出了记忆的选择性也许具有文化特异性的假设。
