That <Emphasis Type="Italic">F</Emphasis>

Jeffrey King’s principal objection to the direct-reference theory of demonstratives is analyzed and criticized. King has responded with a modified version of his original argument aimed at establishing the weaker conclusion that the direct-reference theory of demonstratives is either incomplete or incorrect. It is argued that this fallback argument also fails.

Structural Realism, Scientific Change, and Partial Structures

Scientific change has two important dimensions: conceptual change and structural change. In this paper, I argue that the existence of conceptual change brings serious difficulties for scientific realism, and the existence of structural change makes structural realism look quite implausible. I then sketch an alternative account of scientific change, in terms of partial structures, that accommodates both conceptual and structural changes. The proposal, however, is not realist, and supports a structuralist version of van Fraassen’s constructive empiricism (structural empiricism).     

First-person thought and the use of ‘I’

The traditional account (TA) of first-person thought draws conclusions about this type of thinking from claims made about the first-person pronoun. In this paper I raise a worry for the traditional account. Certain uses of ‘I’ conflict with its conception of the linguistic data. I argue that once the data is analysed correctly, the traditional approach to first-person thought cannot be maintained.     

心理模拟对陆军士兵构建沙盘表征的增强效应

跟随路径的心理模拟是一种想象练习。通过设定对照组检验了基于学习的第一人称和第三人称心理模拟完成方位判断任务和场景再认任务的情况,考察不同心理模拟条件下位置关系表征和视觉记忆表征的构建质量。结果发现,和休息条件相比,第三人称心理模拟和第一人称心理模拟均易于完成方位判断任务和场景再认任务;且第三人称模拟比第一人称心理模拟更易于完成两个任务。结果提示,心理模拟对表征质量有增强效应,场景外强化比场景内强化更易构建表征质量。结果支持位置关系表征一种表征假说。     

基于场景记忆的参照系整合过程中的物体方位判断

以绝对方位中的物体方位判断为实验任务,并按照以往研究把判断过程进行分解为获取目标位置信息、获取前行方向信息和判断目标物体相对于参照物体的方位信息,旨在考察不同信息获取过程下的目标位置和前行方向如何影响基于场景记忆的参照系整合过程中的绝对方位判断。实验1的判断任务同时包括这三个过程;实验2和实验3中的判断任务分别独立于路径描述（即定位后判断,先获知目标位置信息,再进行方位判断）和自身定向（即定向后判断,先获取前行方向信息,再进行方位判断）。每个任务均为目标位置（R0o－前、R45o－左前/右前、R90o－左/右、R135o－左后/右后, R180o－后）×前行方向（北、东南西、斜方向）的组内设计、因变量为正确率和判断时间为主,共有60名大学生被试（男女各半）参与实验。发现：朝北优势效应只在实验1中明显;三个实验任务中均存在正方向－左右位置优势效应、以及0o和180o位置优势效应;目标位置对物体方位判断的影响程度要大于前行方向对判断的影响程度。结合以往的研究来看,场景记忆上的判断比视觉媒介上的同类判断受目标位置影响的程度要大,其他影响模式比较一致。从判断的信息获取过程上对结果进行了讨论,这有助于理解绝对方位判断的认知结构     

反馈相关ERP成分的参照点效应

采用投注—反馈金钱赌博任务具体操作了在结果评价中被试可能采用的参照点,试图进一步探究大脑监控系统是如何对事件的好、坏以及好坏程度进行评定的。实验结果表明,不管是Feedback-related negativity (FRN)还是P300,和赌注相差较小的中间三种反馈诱发的波幅差异不显著,和赌注相差较大的两边两种反馈诱发的波幅和中间三种反馈差异显著。该结果说明,反馈相关ERP成分不是反映了对绝对信息的加工,而是反映了以赌注所在的区间为参照点的相对信息的加工。研究进一步从不同侧面表明FRN所代表的效价评价的参照点效应,同时首次从神经机制上揭示了P300所代表的数量加工的参照点效应     

物体位置与空间关系的心理表征

外界环境中物体位置与空间关系在记忆中如何表征,一直是空间认知研究领域探讨和争论的热点问题。该文从空间表征的参照框架、朝向特异性、组织结构和存储内容四个方面,系统回顾了近年来对空间表征形成机制与内在特征的理论探讨。在此基础上,进一步讨论了当前空间表征研究中存在的生态效度问题,以及以后将虚拟环境技术引入到空间认知研究中的发展趋势     

TOWARD AN EPISTEMOLOGY OF CERTAIN SUBSTANTIVE A PRIORI TRUTHS

Abstract: This article explains and motivates an account of one way in which we might have substantive a priori knowledge in one important class of domains: domains in which the central concepts are response-dependent. The central example will be our knowledge of the connection between something's being harmful and the fact that it is irrational for us to fail to be averse to that thing. The idea is that although the relevant responses (basic aversion in the case of harm, and a kind of interpretive failure in the case of irrationality) are produced by independent psychological mechanisms, they have distal causes that turn out to be related in ways that—once language enters the picture—yield epistemically accessible necessary connections between the referents of their corresponding terms.     

Novel-view scene recognition relies on identifying spatial reference directions

Five experiments investigated whether observer locomotion provides specialized information facilitating novel-view scene recognition. Participants detected a position change after briefly viewing a desktop scene when the table stayed stationary or was rotated and when the observer stayed stationary or locomoted. The results showed that 49° novel-view scene recognition was more accurate when the novel view was caused by observer locomotion than when the novel view was caused by table rotation. However such superiority of observer locomotion disappeared when the to-be-tested viewpoint was indicated during the study phase, when the study viewing direction was indicated during the test phase, and when the novel test view was 98°, and was even reversed when the study viewing direction was indicated during the test phase in the table rotation condition but not in the observer locomotion condition. These results suggest scene recognition relies on the identification of the spatial reference directions of the scene and accurately indicating the spatial reference direction can facilitate scene recognition. The facilitative effect of locomotion occurs because the spatial reference direction of the scene is tracked during locomotion and more accurately identified at test.     

被试自身人手初始状态对心理旋转加工的影响：眼动研

利用眼动追踪技术,探讨在左右手判断任务条件下人手心理旋转加工是否受到被试自身人手初始状态的影响。两个实验的反应时数据和眼动数据均发现：（1）心理旋转加工受被试自身人手初始状态的影响,表现出一致性效应;（2）显著的内旋效应;（3）被试心理旋转加工时注视点取样存在着不均衡性。这些结果表明：在左右手判断任务中,心理旋转加工的对象是被试自身人手的表象,是自我参照的心理旋转,并且内旋效应是由被试对自身人手表象进行旋转时受到人手生理机制约束所致,而不是被试旋转刺激图片的表象由“生理机制约束知识”影响所致
