中小学生语文阅读能力结构的发展特点

本研究对小学六年级、初中三年级、高中三年级三个年龄切面的学生的阅读能力结构构成进行分析,揭示该能力结构的发统特点。结果表明,语文阅读能力结构随年龄的增长而发生变化。一方面表现为因素的数量逐步增加,另一方面表现为比较复杂、层次较高的因素在整个结构中的相对地位不断增强。研究结果进一步指出,该能力结构因素增加的实现方式不同于西方心理学界所认为的分解模式,而是表现为“接替”模式,亦即通过“基础能力因素”对活动的影响作用为新的因素所接替而实现。     

注意对拓扑性质和局部几何性质检测的不同影响──进一步的实验证据

实验研究了中央和外周提示信号对辨别朝向的任务（局部几何性质检测）和辨别有或无的任务（拓扑性质检测）的影响。结果表明,对于两种提示信号,在提示有效和提示无效条件下,辨别有或无比辨别朝向具有较短的反应时和较低的错误报告率;辨别朝向的ＲＴ和错误报告率都受提示信号的影响;而对于辨别有或无的任务,只有ＲＴ受提示信号的影响;提示信号对辨别朝向的影响比辨别有或无的影响大。本实验排除了对Ｈａｎ和Ｃｈｅｎ的实验的可能的光通量解释,并为提示信号对不同几何性质检测的不同影响提供了进一步的实验证据。     

Connecting the dots: Illusory pattern perception predicts belief in conspiracies and the supernatural

A common assumption is that belief in conspiracy theories and supernatural phenomena are grounded in illusory pattern perception. In the present research we systematically tested this assumption. Study 1 revealed that such irrational beliefs are related to perceiving patterns in randomly generated coin toss outcomes. In Study 2, pattern search instructions exerted an indirect effect on irrational beliefs through pattern perception. Study 3 revealed that perceiving patterns in chaotic but not in structured paintings predicted irrational beliefs. In Study 4, we found that agreement with texts supporting paranormal phenomena or conspiracy theories predicted pattern perception. In Study 5, we manipulated belief in a specific conspiracy theory. This manipulation influenced the extent to which people perceive patterns in world events, which in turn predicted unrelated irrational beliefs. We conclude that illusory pattern perception is a central cognitive mechanism accounting for conspiracy theories and supernatural beliefs.     

幼儿在等级图形知觉中的整体优先现象

研究采用Navon的干涉实验范式和等级图形刺激模式研究4-6岁幼儿的整体优先现象。实验中所用刺激的结构关系有一致、无关、矛盾。实验1研究自由注意条件下,不同年龄儿童自发形成整体或局部反应策略的比率,发现被试自发形成对整体特征反应策略的比例较大,且该比例是随年龄而增长的;实验2比较注意整体和注意局部两种实验条件下,不同年龄儿童对整体或局部的反应正确率。结果发现在注意整体和注意局部的条件下,4-6岁幼儿的整体／局部干涉效应呈相互影响到相互独立再到整体优势的发展过程。这表明幼儿对整体特征的注意选择可能是随着年龄增长和视觉经验的积累而逐渐成型的。     

11-15岁学生性格发展模式的研究

本研究以776名11-15岁汉族与白族中小学生为被试,研究了学生性格发展的年龄模式.结果表明,年龄因素对学生性格发展的影响显著,在被测量的24种性格特质中,有18种特质在性质上表现为随年龄的增长而逐步提高的趋势,但是在13岁组发现特质发展的低谷.     

Cosmology: What One Needs to Know

Cosmology, the study of the universe, has a past, which is reviewed here. The standard model—the Big Bang, or the hot, dense early universe that is still expanding—is based on observations that are basically consistent but which require additional input to improve the agreement. Out of the early universe came the galaxies and stars that shine today. The future of the universe depends on the density of matter: too much mass leads to the Big Crunch; too little leads to eternal expans ion and cooling. The dark-matter problem prevents us from knowing which will be the fate of the universe. Thelimits of what may be called "scientific" are addressed.     

Exploring the meso-levels of religious mappings: European religion in regional, urban, and local contexts

This is an introductory essay to a special issue on Local and Regional Perspectives on Religion in Western Europe. The introduction seeks to contextualize this special issue in the study of religion in Europe. Based on the articles of the special issue, the article introduces two meso-levels of investigation: regional and local studies, bridging the gap between the national level (the hitherto preferred level of aggregation) and the study of single groups.     

Local Food Environments: They’re All Stocked Differently

The obesity epidemic has widened the aims of prevention research to include the influence of local food environments on health outcomes. This mixed methods study extends existing research focused on local food environments by examining whether community members’ find food accessible. Data from food store audits and one-on-one interviews were analyzed. Results reveal that most of the food stores surrounding the three research sites were convenience stores and non-chain grocery stores; interviewees did not perceive these stores to be “real” food stores. Tobacco and alcohol products were more prevalent in the food stores than all varieties of milk, fresh fruits, or fresh vegetables. Food access varied by site in a manner that was designed to appeal to customers’ race, class, gender, or environment. Findings reveal that local food environments are reflections of social hierarchies. Unraveling the politics of space ought to be a part of broader efforts to promote the public’s health.     

ACACIA: an agent-based program for simulating behavior to reach long-term goals

We present ACACIA, an agent-based program implemented in Java StarLogo 2.0 that simulates a two-dimensional microworld populated by agents, obstacles and goals. Our program simulates how agents can reach long-term goals by following sensorial-motor couplings (SMCs) that control how the agents interact with their environment and other agents through a process of local categorization. Thus, while acting in accordance with this set of SMCs, the agents reach their goals through the emergence of global behaviors. This agent-based simulation program would allow us to understand some psychological processes such as planning behavior from the point of view that the complexity of these processes is the result of agent–environment interaction.     

基于属性掌握概率的认知诊断计算机化自适应测验选题策略

在认知诊断计算机化自适应测验(CD-CAT)中, 被试对每个属性的掌握概率更直接地反映了被试能力的当前估计值。因此, 基于被试的属性掌握概率来构建选题策略, 选择最能改变被试属性掌握概率的题目作为下一个测验项目, 这应该是一个值得尝试的方案。本文借鉴已有相关研究的数据生成模式进行探索, 模拟实验结果表明：假设属性间相互独立,在定长(长度为16)、变长(长度为16或后验属性掌握模式概率达到0.8)以及短测验(长度分别为4、6、8、10)的情况下, 基于属性掌握概率的选题策略PPWKL和PHKL有较好的分类准确率, 在题目曝光率, 题库使用均匀性等方面也有较好的表现; 与研究较多的PWKL、HKL等策略相比, 也略有优势; 当属性间存在不同程度的相关时, 在定长、变长以及较短的测验条件下, 基于PHKL和MI的测验对知识状态估计精度较好, 基于PPWKL和PHKL的测验综合表现占优。
