Effects of circular motion on judgment of rotation direction and depth order in visual motion

Abstract:  The rotation direction and depth order of a rotating sphere consisting of random dots often reverses while it is viewed under orthographic projection. However, if a short viewing distance is simulated under perspective projection, the correct rotation direction can be perceived. There are two motion cues for the rotation direction and depth order. One is the speed cue; points with higher velocities are closer to the observer. The other is the vertical motion cue; vertical motion is induced when the dots recede from or approach the observer. It was examined whether circular motion, which does not have any depth information but induces vertical velocities, masks the vertical motion cue. In Experiment 1, the effects of circular motion on the judgment of the rotation direction of a rotating sphere were examined. The magnitude of the two cues (the speed cue and the vertical velocity cue) as well as the angular speed of circular motion was varied. It was found that the performance improved as the vertical velocity increased and that the speed cue had slight effects on the judgment of the rotation direction. It was also found that the performance worsened as the angular speed of the circular motion was increased. In Experiment 2, the effects of circular motion on depth judgment of a rotating half sphere were investigated. The performance worsened as the angular speed of the circular motion increased, as in Experiment 1. These results suggest that the visual system cannot compensate perfectly for circular motion for the judgment of the rotation direction and depth order.     

3~5岁幼儿自我控制能力结构研究

运用验证性因素分析的方法得出我国3~5岁幼儿自我控制能力结构由自制力、坚持性、自觉性和自我延迟满足四个维度组成,四个维度之间既相互独立又相互联系.依据验证的结果设计了两个幼儿自我控制的现场实验,将实验结果与问卷结果相比较,二者存在着高度的一致性,问卷具有良好的信度和效度.     

人造物概念的表征：功能、意图和目的论的解释

以概念结构研究从“相似”到“解释”的理论转向为背景,评述人造物领域的“意图-历史论”（Bloom, 1996）,提出人造物概念结构中自上而下的约束是来自“使用目的”而不是“设计意图”。分析近期报告的大量实验,最后提出人造物概念表征的“基于使用的目的论”的解释模式和人造物归类的双重目标模型。     

关于健康观认知构造的中日比较研究

本研究的目的是揭示大学生关于健康观的认知构造,并对中日大学生健康观的认知构造进行比较。通过对收集到的日常生活的健康观数据进行处理,制成了一个包含50个项目的问卷,然后对收集到的儿8名日本大学生和81名中国大学生的数据进行了因子分析,得到了健康观认知构造的五个因子,即“自律性”(因子Ⅰ)、“主观自我”(因子Ⅱ)、“身体因素”(因子Ⅲ)、“心理因素”(因子Ⅳ)、“健康习惯”(因子Ⅴ)。中日学生的健康观认知结构在Ⅰ、Ⅲ、Ⅳ因子上存在差异。     

“犯罪人心理”与“犯罪心理”辨析

关于“犯罪心理结构”之争,已经集中在“犯罪心理”或“犯罪人心理”这个焦点上。反对“犯罪心理结构”者认为,犯罪心理实际上是不存在的,犯罪人心理在很多方面（甚至一切方面）同守法公民没有区别。因此,犯罪心理学实际上是一门研究“犯罪人心理”的学科。笔者认为,这是一种违反逻辑的、必将导致取消犯罪心理学的推论。     

Cognitive Behavior Therapy for Older Adults: Practical Guidelines for Adapting Therapy Structure

Cognitive behavioral therapy (CBT) has been shown to be an effective approach for a wide range of problems affecting older adults. While a variety of empirical and clinical papers have examined modifications to the content and delivery of CBT to enhance its efficacy with older adults, changes to the structure of therapy with this population have not been as widely discussed. Issues around optimizing the structure of CBT with older adults are presented, along with suggestions for realizing these changes within a clinical context.     

农村选民选举行为的结构特征

以云南省两个县八个自然村的 2 62名选民为被试 ,采用心理测量原理与技术探讨了农村选民选举行为的结构特征。结果表明 ,政见取向由“政策效应”、“民生意识”、“村民权益”和“监督机制”4个因素构成 ,非政见取向由“候选人身份”、“候选人德能”、“选民社会关系”、“候选人背景”、“选民自我利益”、“选民自我权利”和“政党意见”7个因素构成。经检验 ,由此构成的农村选举行为问卷具有较高的内部一致性 ,问卷项目具有较高的区分度。文章讨论了农村选民选举行为的结构特征及其意义。     

The Embodiment Thesis

In this essay I articulate and defend a thesis about the nature of morality called “the embodiment thesis”. The embodiment thesis states that moral values underdetermine the obligations and entitlements of individual persons, and that actual social institutions must embody morality by specifying these moral relations. I begin by presenting two thought experiments that elucidate and motivate the embodiment thesis. I then proceed by distinguishing the embodiment thesis from a Rawlsian doctrine about the nature of justice, from the doctrine of moral relativism, and from solutions to the coordination problem of rational choice theory.     

基诺族亲属词概念结构的特点及其成因

运用自然分类和多维标度方法,探讨基诺族中学生的亲属词概念结构特点。结果发现,基诺族亲属词概念结构有两个维度：(1)亲密程度;(2)照顾者／被照顾者。这与汉族中学生的亲属词概念结构既有相同之处,又有明显差异。这与基诺族的血缘婚制度以及马来亚式亲属制度等历史积淀有关,也与基诺族跨越式发展中他文化的渗透和主文化的变迁有关。     

以实质心理学为基础的评估：认知诊断

评价除了了解学习者的学习情况外,同时还应该提供学习者学习状况的诊断信息,以利于教学与学习。评价应该以认知心理学对学习过程的研究,作为编制测验的实质理论依据,进行认知诊断评估。本文针对认知诊断的心理学基础：知识的习得、知识诱发、知识表征、知识结构等进行梳理,以便测验开发者对认知诊断评估有更清晰的认识。
