颜色凸显条件下基于工作记忆内容的视觉注意

采用记忆任务与视觉搜索任务相结合的实验范式,通过操纵背景颜色与刺激颜色,考察了工作记忆内容对视觉注意的引导是否存在强自动性。实验一通过操作背景颜色以突显记忆项目,结果发现即使工作记忆内容在匹配分心物的情况下仍然自动地捕获视觉注意。实验二通过操作背景颜色以突显目标项目,结果发现工作记忆内容对视觉注意的自动引导作用消失。说明了与工作记忆内容匹配的刺激能够自动地引导视觉注意,但是这种引导并非完全自动化,具有一定的条件性。     

弗雷格《概念文字》理解的两点注记

文章旨在简要地讨论弗雷格《概念文字》,指出其中的两个重要但被一些国内学者误解或忽略的贡献：首先我们指出,根据Boolos等人的论证,弗雷格《概念文字》中的逻辑本质上是带完整二阶存在概括规则的二阶逻辑,这点在国内一些学者的著作与文章中存在误解;其次,我们讨论弗雷格如何用遗传性概念来定义祖先关系,进而定义自然数或有穷数,并使得数学归纳法仅根据自然数的定义就得以成立,这也为弗雷格把算术还原为逻辑奠定了基础。     

我国3～6岁儿童个性类型及发展特点的研究

该文在以往中国儿童个性结构研究基础上,以问卷调查（n=927）方式,将层次聚类和迭代聚类两种方法结合起来,同时采用理论分析等方法最终确定我国3～6岁儿童的个性类型包括认可型、矛盾型、拒绝型及中间型四类。其中认可型属于积极个性类型,矛盾型和拒绝型属于消极个性类型。研究表明,中班到大班阶段是幼儿个性发展相对重要的时期。男女幼儿在多个个性维度及大部分具体特质方面存在着明显的性别差异。     

死亡凸显对自我姓名注意瞬脱对抗效应的影响

已有研究表明死亡凸显会抑制自我面孔和自我参照记忆加工的自我优势,可是死亡凸显对自我姓名的影响尚不明确,本研究采用事件相关电位技术,探索死亡凸显对自我姓名注意瞬脱对抗效应及其大脑神经活动的影响。58名被试在经历不同的启动任务后,完成自我姓名、朋友姓名和名人姓名的注意瞬脱任务。行为结果发现自我姓名识别正确率显著高于朋友姓名和名人姓名,表现出稳定的自我姓名加工的注意瞬脱对抗效应;电生理数据发现死亡启动后自我姓名诱发的P300波幅显著低于消极启动组和中性启动组,而朋友姓名和名人姓名并不受启动的影响。本研究结果与以往研究结果共同表明死亡想法凸显会使个体将抑制自我加工（自我姓名、自我面孔和自我参照记忆）作为应对远端死亡焦虑的一种手段。     

从现代逻辑观点看中国古代的有效推理

中国古代逻辑也是研究推理和论证的。推理和论证的主要目的是揭示一个命题为真的原因或理由。推理关系是一种 ＂必然地得出＂ 的关系。墨子提出了四种推理模式：＂辟＂、＂侔＂、＂援＂、＂推＂,而且把 ＂推＂ 又分为两种 ＂止＂,即归纳＂止＂ 式推论和演绎 ＂止＂ 式推论。特别地,墨家提出了 ＂效＂ 作为判定推理是否有效的标准。     

Beliefs and preferences in cultural agents and cultural game players

Two laboratory experiments demonstrated that Japanese participants did not conform to the majority unless negative social implications of not conforming were clear. When their behaviour had no implications for others, they rather exhibited preference for uniqueness. Results of Study 2 further demonstrated that participants' conformity to the majority was particularly prevalent among those who were chronically concerned with how other people would perceive them. Participants in these studies were shown to be cultural game players who changed their behaviour in response to anticipated responses of others based on culturally shared beliefs.

Multidimensional scaling reveals two dimensions of thermal pain

The Individual Differences Scaling (INDSCAL) model of multidimensional scaling was used to explore the dimensions of thermal pain. The observers made 66 similarity judgments to all pairs of 12 different thermal stimulus intensities ranging from zero to noxious. Analysis of the data revealed a two-dimensional group stimulus space. The major dimension ordered the stimuli with respect to their intensity. This quantitative, strength-of-sensation dimension may be interpreted as indicating how weak or strong a stimulus feels, apart from any secondary qualities of warmth or pain. The second dimension was related to the qualitative aspects of the stimuli. This bipolar dimension contained two attributes: a pain attribute ranging from just detectable warmth to painful, and a warm-hot attribute running from just detectable warmth to hot. This study demonstrates the utility of the INDSCAL approach to the understanding of pain and offers a new technique for answering the age-old question concerning the number and qualities of the dimensions underlying the pain experience.     

Weakening the robustness of perspective: Evidence for a modified theory of compensation in picture perception

Viewed from the center of projection, a perspective picture presents the pictorial depth information of a scene. Knowing the center of projection, one can reconstruct the depicted scene. Assuming another viewpoint is the center of projection will cause one to reconstruct a transformed scene. Despite these transformations, we appreciate pictures from other viewpoints. The compensation hypothesis states that the visible picture surface allows observers to compensate for transformations by locating the center of projection and experiencing pictorial space from there. We show that observers neither completely compensate for nor experience transformations of space as geometry would predict. We propose a modified compensation hypothesis according to which different degrees of visibility of the picture surface invoke different degrees of compensation.
