同步内隐／外显序列学习：事件相关的fMRI的初步研究

本文利用事件相关fMRI研究探讨对于内隐和外显学习在脑区激活上的差异.实验采用同步内隐/外显学习序列,以有色的形状作为刺激材料.要求被试对于刺激的颜色做选择反应,并在颜色消失后找出形状的内在规则.颜色和图形序列分别采用两个独立的马尔可夫链,即下一个图形的颜色或者形状有70%的可能服从序列规则.行为数据显示被试习得了外显和内隐的规则,fMRI成像主要比较内隐和外显学习在学习过程和知识运用上脑区激活的差异.结果发现,与内隐学习柑比,外显学习在额叶的激活更为显著.而且,内隐学习和外显学习在视觉皮层的激活出现分离,内隐学习中枕叶的激活减弱,而外显学习中枕叶的激活增加.     

简单结构刺激非规则特征突显条件下的样例效应

用变化了的Allen和Brooks的实验范式,采用2(学习轮次:5轮、10轮)×2(项目类型:旧项目、新项目)×2(项目匹配性质:正向匹配、反向匹配)混合实验设计,研究对4个特征刺激分类时非规则特征突显条件下的样例效应。结果发现,无论是错误率还是反应时都取得了明显的样例效应,但是学习时间的影响不明显。     

从李丽云事件看生命健康权、患者自主权和医生干涉权

当患方行使自主权所做的决定危及自身生命健康权时,能否赋予医生干涉权以实现生命高于一切的理念？阐明了生命健康权、患者自主权和医生干涉权的关系．并从我国实际出发,论述不能通过赋予医生干涉权来避免类似李丽云悲剧的发生,建议立法完善对民事行为能力的规定,建立司法机关或其他第三方机构提前快速审查机制来解决自主权与生命权的冲突。     

言语产生过程中语义、语音激活的ERP研究

使用ERP技术考察了言语产生过程中语音和语义的激活情况。图片上有3种条件的干扰词,分别与目标图片名称形成3种关系:语义相关,语音相同,语义、语音、字形都不相关。结果显示,当被试执行延迟命名任务(实验1)时,与目标图片名称语义相关和控制条件的波形比语音相关的波形更趋于负向。说明在图片命名过程中语音有明显的促进作用。当要求被试对上述图片进行延迟语义判断任务(实验2)时,与目标图片名称语义相关、语音相关及控制条件的波形之间无明显差异。说明在语义提取过程中没有语音的促进作用。综合实验1和实验2,本研究的结果更倾向于支持独立两阶段模型。     

巴门尼德残篇中的Aletheia

本文分析了巴门尼德残篇中出现的Aletheia这个概念,认为通常在与“意见”相对立的“真理”的意义上理解Aletheia是不合适的。这个概念与“是”、“是者”直接相关,甚至可以作为“是者是”这个命题的主词。在巴门尼德的残篇中Aletheia显示了它的独特性,既是女神话语的一种绝对担保,又在一种典型的古希腊式的论辩气氛中维持着自身的自满自足,为其后的思想开辟出一条新的道路。文章借用海德格尔的视野论述了Aletheia这个问题在思想上显示出来的重要性,并试图将“是者是”这个命题所道出的“同一性”摆置到其源出的位置上去。     

The Historical Effect of Habermas in the Chinese Context: A Case Study of the Structural Transformation of the Public Sphere

The main purpose of this essay is not to give a full-scale and systematic exploration of the historical process concerning the acceptance of Habermas’ works in the Chinese-spoken world but to examine the historical effect of Habermas in the Chinese-spoken context and try to find a proper way to establish a good relationship between Habermas and the Chinese-spoken world by discussing the introduction, study, and application of Habermas’ most famous work, The Structural Transformation of the Public Sphere, by Chinese scholars in recent years. Translated from Xiandai zhexue, 2005:1     

Item frequency in probe-recognition memory search: Converging evidence for a role of item-response learning

In short-term probe-recognition tasks, observers make speeded old–new recognition judgments for items that are members of short lists. However, long-term memory (LTM) for items from previous lists influences current-list performance. The current experiment pursued the nature of these long-term influences—in particular, whether they emerged from item-familiarity or item-response-learning mechanisms. Subjects engaged in varied-mapping (VM) and consistent-mapping (CM) short-term probe-recognition tasks (e.g., Schneider & Shiffrin, Psychological Review, 84, 1–66, 1977). The key manipulation was to vary the frequency with which individual items were presented across trials. We observed a striking dissociation: Whereas increased presentation frequency led to benefits in performance for both old and new test probes in CM search, it resulted in interference effects for both old and new test probes in VM search. Formal modeling suggested that a form of item-response learning took place in both conditions: Each presentation of a test probe led to the storage of that test probe—along with its associated “old” or “new” response—as an exemplar in LTM. These item-response pairs were retrieved along with current-list items in driving observers’ old-– recognition judgments. We conclude that item-response learning is a core component of the LTM mechanisms that influence CM and VM memory search.     

Cultural influences on terror management: Independent and interdependent self-esteem as anxiety buffers

Terror management theory (TMT) proposes that self-esteem serves as a defense against the fear of death. Previous research has suggested that independent self-esteem is more salient in individualist cultures, whereas interdependent self-esteem is more salient in collectivist cultures. Thus, we hypothesized that in collectivist cultures, independent self-esteem would play a lesser role and interdependent self-esteem a greater role in terror management, compared to individualist cultures. The results support this prediction. In Study 1, personal self-esteem was negatively associated with death anxiety in samples from a Western (Austria) and Eastern (China) culture. However, both self-liking and self-competence were negatively associated with death anxiety among Austrian participants, but only self-liking (and not self-competence) was so among Chinese participants. Surprisingly, collective self-esteem was not significantly correlated with death anxiety. Yet, Study 2 showed that among Chinese participants, relational self-esteem was negatively associated with death anxiety. Study 3 examined the roles of relational versus personal self-esteem in moderating the effects of mortality salience on worldview defense. Among Chinese participants, relational rather than personal self-esteem increased the defense of worldviews centered on collectivist-Chinese values following mortality salience (Study 3a). In contrast, among Austrian participants, personal rather than relational self-esteem attenuated the effect of mortality salience on the defense of individualist-Austrian worldviews (Study 3b). Self-esteem serves a terror management function in both collectivist and individualist cultures; however, the differences between cultural worldviews determine the type of self-esteem that is more relevant to terror management processes.     

Factors affecting the involvement of teachers in guidance and counselling as a whole-school approach

This study explores factors affecting the involvement of regular secondary school teachers in the whole-school approach to guidance and counselling by interviewing 12 secondary school teachers in Hong Kong. Emerging themes include teachers' ownership of their role in student guidance and counselling, the alignment of their disposition with education policies, school missions and culture, and their philosophy in education. Findings of what these teachers are actually doing in guidance and counselling are presented. Implications for policy-makers, administrators and leaders for comprehensive guidance and counselling programmes are drawn from constraints that limit interviewees' full potential in assisting students.     

Internet Addiction and Well-Being: Daoist and Stoic Reflections

This article explores the phenomenon of Internet addiction and its possible amelioration, from both Eastern and Western philosophical perspectives. Internet addiction is caused by the excessive use of the Internet and its resulting dependence, having negative effects on human well-being. The ideas of a key ancient Chinese Daoist thinker Zhuangzi 莊子 and his Western contemporaries, the Stoics, as viewed through the world, the things and beings in it, and their relationships, offer insights which may be used to alleviate these effects. The application of and comparison between the two ancient philosophies in addressing the issue of Internet addiction can give us inspiration to confront the challenges of technological enslavement in general and Internet addiction in particular. This is no doubt a help in our pursuit of well-being.
