永生即厌倦——论B.威廉斯的永生观

B.威廉斯在其论文《马克洛普罗事件:对永生之厌倦的反思》中认为,永生是没有意义的。威廉斯指出死亡与有死是不同的,若永生则厌倦;只有满足同一性与吸引力两个条件,永生才不会无聊。尽管威廉斯的理论遭到一些学者的反驳,但本文通过分析得出,威廉斯的这一理论是深刻而富有洞见的。当然他的理论也不是无懈可击的,其同一性条件太严又太宽,但无论如何也不影响永生导致无聊的判断,因为破除对永生的期待,才可让有限的生命更有意义。     

神经美学视角的审美愉悦加工机制

审美对象特有的刺激属性会唤起观赏者特定的情绪或情感反应。个体在欣赏自然、艺术品和其他人类作品时会产生审美愉悦体验。审美愉悦-兴趣模型(PIA)认为, 审美愉悦体验包含审美过程中自动化加工阶段的审美愉悦和控制加工阶段的审美兴趣。近年来, 神经美学研究表明, 负责愉悦和奖赏的眶额叶皮层在审美过程中广泛激活, 是自动化加工阶段初级审美愉悦奖赏的神经基础, 而审美过程中纹状体亚回路中不同的连接和功能作用与两个阶段中审美愉悦的产生都有关联; 上述结果支持了审美愉悦-兴趣模型。但审美高峰体验时默认模式网络(DMN)相关脑区的激活和负责控制与理性思维的外侧前额叶皮层等脑区的失活, 提示在PIA模型强调的自动化加工阶段审美愉悦和控制加工阶段审美兴趣之上, 还有整合升华阶段的审美沉浸愉悦, PIA模型需得到进一步的扩展。未来研究应进一步检验审美愉悦认知加工模型及神经机制, 探索审美对创造力的影响机制和神经基础, 探讨不同审美经验愉悦机制的异同。     

刷微博，让焦虑的人更焦虑——特质焦虑对青少年注意情绪刺激的影响

采用自由观看眼动追踪范式,考察特质焦虑青少年在观看情绪面孔图片过程中的眼动轨迹。结果发现,高特质焦虑组对愤怒和恐惧面孔的首次注视到达时间（TFF）较快,首次注视持续时间（TFD）较短;低特质焦虑组对愤怒和恐惧面孔的TFF虽然稍早于平静面孔,但差异不显著。在刺激呈现1000ms之后,高特质焦虑组对愤怒和恐惧面孔的注视次数（FC）较多,平均注视持续时间（AFD）较短。低特质焦虑组对愤怒和恐惧面孔的FC较少,AFD较长;这就表明,高特质焦虑青少年在认知加工早期对威胁性刺激注意定向加速,没有注意解除困难,呈现“浅尝辄止”现象。而在认知加工晚期,他们则对威胁性刺激存在“反刍”现象。     

Re-examining Citizenship: How the Control of Measurement Artifacts Affects Observed Relationships of Organizational Citizenship Behavior and Organizational Variables

We examined the impact that measurement artifacts (antithetical items that overlap counterproductive work behavior (CWB), agreement response, halo in supervisor ratings) in organizational citizenship behavior (OCB) measures has on observed relationships between OCB and 15 predictors. Respondents were 146 employees and their supervisors who completed surveys that included OCB measures with and without artifacts. Predictors (conscientiousness, emotional stability, empathy, distributive justice, procedural justice, role ambiguity, role conflict, leader–member exchange, affective organizational commitment, job satisfaction, negative and positive emotion, turnover intention, CWB, and task performance) were chosen that related to OCB in prior meta-analyses. Results with the OCB scale with artifacts were consistent with meta-analyses, whereas results with the artifact-controlled OCB scale were not, suggesting that accepted conclusions about OCB’s relationships with many other variables should be reexamined.     

A new EOG-based eyeblink detection algorithm

Accurate and efficient operator functional state classification and assessment based on physiological data have many important applications ranging from operator monitoring to interaction and control of human/machine systems. Eyeblink characteristics are frequently used as physiological indicators for this purpose. In this paper, we describe an efficient and robust eyeblink detection algorithm based on nonlinear analysis of the electrooculogram (EOG) signal. The performance of the algorithm was evaluated via data analysis results of several benchmark test sets in comparison with another eyeblink detection algorithm.     

听障大学生汉语阅读中的绕口令效应：口语经验和阅读能力的影响

听障者阅读时是否激活语音信息是听障者阅读研究领域的热点问题之一。本研究使用眼动技术,采用绕口令材料,考察口语经验和阅读能力对听障大学生汉语阅读中语音激活的影响。结果发现,口语经验较多且阅读能力较高(OHRH)的听障大学生的绕口令效应大于口语经验较少但阅读能力较高(OLRH)的听障大学生,OLRH组的绕口令效应大于口语经验较少且阅读能力较低(OLRL)的听障大学生。局部指标分析发现OHRH和OLRH组在早期和晚期指标上均存在绕口令效应,OLRL组只在晚期指标上才出现绕口令效应。结果表明,口语经验和阅读能力影响听障大学生汉语阅读中的语音激活。     

羞怯对攻击的影响:安全感和社会比较倾向的中介作用

为考察安全感和社会比较倾向在羞怯与攻击之间关系的中介作用,采用大学生羞怯量表、社会比较倾向量表、安全感量表和攻击问卷对543名大学生进行测量。结果发现(1)羞怯、攻击和社会比较倾向三者之间呈显著两两正相关,且三者分别与安全感呈显著负相关;(2)羞怯对攻击的直接效应显著;(3)安全感和社会比较倾向在羞怯与攻击关系间起完全中介作用。     

Microblogging, online expression, and political efficacy among young chinese citizens: the moderating role of information and entertainment needs in the use of weibo

In 2011, China's Internet population reached over half a billion users and the popular Twitter-like social networking service, Weibo, has been adopted by half of the users since its launch in August 2009. Given the potential of the Internet to facilitate a civic culture in the authoritarian state, the use of Weibo and its effects on citizens' political attitudes and behaviors are of important concern. A survey of 499 Weibo users found that intensity of use was related to increased willingness to express opinions about government and politics, the perception that one has the ability to participate in politics, and feelings that the government is not responsive to the demands of citizens. Moreover, the above relationships were moderated by the motivations of Weibo use, such that information motives strengthened the relationships while entertainment motives weakened the relationships.     

保证知识论与基督教信念

Alvin Plantinga后期建立了保证的知识论,并在此架构下对有神信念辩护。他主要是回应启蒙运动以来的对有神信念知识上批判。Plantinga认为这些启蒙批判事先预设了有神信念为假,因此不是知识上有效的反驳。有些批评认为Plantinga的论证结构有问题。本文介绍这些批评,指出Planinga的论证有两个背景,分别是保证的知识结构和改革宗的预设护教学。补充完整背景后,Plantinga的论证策略不仅可以理解,也可以回应批评。尽管Plantinga的论证可成立,但他对启蒙批判的理解有误。本文指出,启蒙批判的本体立场乃是自然主义,并介绍反自然主义的论证,结论是有神信念比之自然主义有知识上的优势。
