自由观看实景图片时注意的空间偏向

本研究采用眼动仪直接记录40名在校大学生及研究生（平均年龄21.9岁,SD=1.8）自由观看实景图片的眼动情况,考察自然状态下视觉注意在真实场景中的空间偏向。为了控制图片不同区域刺激特征显著性对结果的影响,将被试随机分为两组,一组观看正向图片,一组观看倒置图片。对图片四个象限上的首次注视概率、首次眼跳方向和注视时间百分比分别进行2（水平方向）×2（垂直方向）×2（呈现方式）的重复测量方差分析,结果表明,存在独立于刺激特征的空间注意偏向,表现在水平方向具有左侧注意偏向,垂直方向具有上侧注意偏向。     

对想象环境的空间更新

学界传统上将空间更新定义为个体随着身体运动对其所处真实环境空间表征的自动更新过程, 然而近年来有研究发现个体还可以对想象环境进行空间更新, 但其机制尚不明确。本研究实验1被试站在场景内学习物体空间位置之后, 保持学习朝向直线走到测试位置。其中, 0度组保持学习朝向站立, 180度组原地转动180度, 面对学习朝向的相反方向站立。两组被试均想象自己仍然站在学习位置, 面对学习朝向。然后被试旋转90度, 从3个想象朝向(记忆一致朝向、感觉运动一致朝向和不一致朝向)完成空间判断任务。结果发现0度组记忆一致朝向和感觉运动一致朝向成绩均优于不一致朝向, 而180度组无此优势。实验2被试从学习空间移动到测试空间过程中被迷向, 其他条件与实验1的180度组相同。但是, 实验2被试在记忆一致朝向和感觉运动一致朝向的成绩均优于不一致朝向。结果证明人们可以通过对在线空间表征进行想象平移或将离线记忆与空间更新系统相联结两种方式, 对想象环境进行空间更新。     

上下意象图式对羌族亲属词认知的影响

采用亲属词判断任务和真假词判断任务, 考查了“上下意象图式”对羌族被试认知隐含辈分关系的羌族亲属词的影响, 并通过空间识别任务检验亲属词辈份概念加工能否自动地激活空间意象图式, 引导空间注意朝向与空间意象图式一致的位置。实验1表明, 在羌族被试对羌族亲属词的认知中, 存在着“隐喻一致性效应”：高辈分的亲属词呈现在计算机屏幕的上方加工得更快, 低辈分的亲属词呈现在计算机屏幕的下方加工得更快。实验2表明, 当目标刺激的空间位置与亲属词的辈分信息一致时, 羌族被试对目标刺激的辨认速度更快。整个研究表明, 羌族亲属词隐含的辈分关系可以用垂直空间关系来理解, 并引导被试的空间注意朝向与上下意象图式一致的位置, 证明对抽象概念的理解基于感觉运动的加工, 符合概念隐喻理论的预言。     

视觉注意选择性的空间位置效应的研究

采用注意线索技术探讨颜色、角度和空间位置对视觉选择性注意的影响。研究结果表明 :( 1 )目标与干扰刺激颜色相同时 ,表现出明显的注意空间位置效应 ;( 2 )目标与干扰刺激颜色不同时 ,空间位置效应明显弱化 ;( 3 )整体而言 ,注意加工速度从左到右均表现出明显的“V”字形效应。     

顶叶在特征捆绑中的作用--对一例典型双侧顶叶损伤病人的研究

本实验以一例典型双侧顶叶损伤患者为研究对象,以数字和几何形状为材料,采用形状和颜色特征识别任务,主要考察了顶叶及空间信息是否影响视觉特征捆绑。结果显示,患者在特征捆绑任务上操作成绩较差,错觉性结合错误远远多于特征错误,且正确反应及错觉性结合受刺激间的距离及呈现方式的影响,表现出距离和位置效应。这些结果表明,顶叶在视觉特征捆绑中起重要作用,这种影响作用很可能与空间注意有关。本研究进一步为特征整合理论提供了神经心理学的证据。     

幼儿心理状态术语的运用与心理理论的发展

本研究目的在于探讨幼儿在假装游戏中心理状态术语的应用,以及与错误信念的理解是否存在相关并具有一定的发展特征。57名3—5岁的幼儿参加了实验。研究程序包括两类标准错误信念任务及假装游戏的拍摄、麦卡锡幼儿言语智力测验。结果发现：(1)幼儿的一般言语能力与错误信念的理解存在显著相关;(2)幼儿心理状态术语的使用存在情境差异,且随年龄的增长具有“指向愿望一指向信念”的维度特征;(3)在控制相关因素之后,幼儿错误信念的理解与心理状态术语的应用及其特定范畴(习惯用语)之间仍然存在显著相关;与“真正涉及心理状态”之间的相关不再显著。     

The Theological Structure of Christian Faith and the Feasibility of a Global Ecological Ethic

Scientific evolutionary/ecological thinking is the basis for today's understanding that we are now in an ecological crisis. Religions, however, often resist reordering their thinking in light of scientific ideas, and this presents difficulties in trying to develop a viable global ecological ethic. In both the West and Asia religiomoral ecological concerns continue to be formulated largely in terms of traditional concepts rather than in more global terms, as scientific thinking about ecological matters might encourage them to do. The majority of this article is devoted to the kind of reformulation of Western Christian conceptions of God, humanity, and the relation between them that is necessary to address this problem. The question is then raised whether similar critical thinking about religiomoral issues raised by today's evolutionary/ecological scientific thinking is going on in Asian religions and whether it would be too presumptuous (in view of our colonial history) for us Westerners to ask for such rethinking. This leads to a final question: Without such transformations in religious traditions East and West, is the development of a truly global ecological ethic really feasible?     

Referential Intentions and Communicative Luck

Brian Loar [1976] observed that communicative success with singular terms requires more than correct referent assignment. For communicative success to be achieved, the audience must assign the right referent in the right way. Loar, and others since, took this to motivate Fregean accounts of the semantics of singular terms. Ray Buchanan [2014] has recently responded, maintaining that, although Loar is correct to claim that communicative success with singular terms requires more than correct referent assignment, this is compatible with direct reference approaches, as long as one also endorses an independently motivated Gricean view of communicative intentions. This paper argues that Buchanan's Gricean view cannot account for the full range of Loar cases. In doing so, it aims to explicate the structure of Loar's cases and thus to clarify the conditions that a theory must meet in order to adequately meet his challenge.     

Paradigm Terms: The Necessity of Kind Term Identifications Generalized

Standard Kripke-Putnam semantics is widely taken to entail that theoretical identifications like ‘Brontosauruses are Apatosauruses’ or ‘Gold is ⁷⁹Au’ are necessary, if true. I offer a new diagnosis as to why this modal consequence ensues. Central to my diagnosis is the concept of a paradigm term. I argue that modal and epistemic peculiarities that are commonly considered as distinctive of natural kind expressions are in fact traits that are shared by paradigm terms in general. Philosophical semantics should broaden its focus from natural kind expressions to paradigm terms.     

Motor Planning Influences the Perceived Timing of Vibrotactile Stimuli in an Amplitude-Dependent Manner

The authors characterized how motor planning influences temporal order judgment (TOJ) tasks. They examined this by applying vibrotactile stimulation during the planning stages of a bimanual arm movement that would bring the arms into a crossed configuration. The authors have previously shown that planning to cross the arms induces a subjective reversal of spatially defined temporal order judgments that evolves over the course of the planning period. It was unclear, however, whether this effect is modulated by the extent to which the arms would be crossed after movement. The authors examined this issue by having participants plan to move to 4 different targets that would leave the arms in crossed configurations of varying extents. The results demonstrate that even though cutaneous stimuli were applied before the movements, if participants were planning to move into a more crossed configuration, performance on the TOJ task worsened depending on where they were in the planning process. This data suggest the brain uses planning signals to predict sensations from impending movements in a context-dependent manner.
