当代中国的社会转型

本文以我国社会生活发生的广泛而深刻的变化为背景,深入揭示了这种变化深层的社会转型。这种转型就是：由权力社会走向能力社会;由人治社会走向法治社会;由人情社会走向理性社会;由依附社会走向自立社会;由身份社会走向实力社会;由注重先天给定社会走向注重后天努力社会;由一元化社会走向多样化社会;由人的依赖社会走向物的依赖社会;由静态社会走向流动社会;由“国家”社会走向“市民”社会。     

Inferring the structure of latent class

Present optimization techniques in latent class analysis apply the expectation maximization algorithm or the Newton-Raphson algorithm for optimizing the parameter values of a prespecified model. These techniques can be used to find maximum likelihood estimates of the parameters, given the specified structure of the model, which is defined by the number of classes and, possibly, fixation and equality constraints. The model structure is usually chosen on theoretical grounds. A large variety of structurally different latent class models can be compared using goodness-of-fit indices of the chi-square family, Akaike’s information criterion, the Bayesian information criterion, and various other statistics. However, finding the optimal structure for a given goodness-of-fit index often requires a lengthy search in which all kinds of model structures are tested. Moreover, solutions may depend on the choice of initial values for the parameters. This article presents a new method by which one can simultaneously infer the model structure from the data and optimize the parameter values. The method consists of a genetic algorithm in which any goodness-of-fit index can be used as a fitness criterion. In a number of test cases in which data sets from the literature were used, it is shown that this method provides models that fit equally well as or better than the models suggested in the original articles.     

句子语境中汉语词汇歧义消解的ERP研究

采用ERP方法,考察了汉语词汇歧义消解中句子语境作用的时间进程及大脑活动。目标词与句子语境存在一致、不一致、无关控制等3种关系。结果显示:(1)一致与不一致条件下N400的平均波幅均显著低于无关控制条件;(2)SOA为200毫秒时产生的N400平均波幅的幅度显著高于SOA为1000毫秒的条件;(3)N400的平均波幅及潜伏期均表现出左半球显著高于右半球的特点。实验结果支持词汇歧义消解的模块化观点,体现了大脑两半球语言功能的不对称性。     

What response times tell of children's behavior on the balance scale task

Analysis of accuracy of responses to balance scale problems gives a global idea of the cognitive processes that underlie problem-solving behavior on this task. We show that response times (RTs) provide additional detailed information about the kind and duration of these processes. We derive predictions about the RTs from Siegler's (1981) model for the balance scale task, including the counterintuitive prediction that young adults are slower than children in solving particular balance scale problems. The predictions were tested in a study in which 191 6- to 22-year-old participants were presented with a computerized balance scale task. RTs were analyzed with regression models. In addition to qualitative differences between items, we also modeled quantitative differences between items in the regression models. Analyses supported the predictions and provided additional knowledge on the rules. Rule II was reformulated as a rule that always involves the encoding, but not always the correct application of the distance cue. RTs provided evidence for the use of a buggy-rule and not an addition-rule. Finally, a relation between rule inconsistency and increased RT was found.     

You’re Better Respected When You Carry Yourself as a Man: Black Men’s Personal Accounts of the Down Low “lifestyle”

Although the notion of a down low life style, called various things at various times, has a long history in the black community, the past few years have been marked by an exponential increase in attention of this phenomenon in both the mainstream press and scholarly work. However, much of this work has focused on exploring whether men on the down low present a unique threat for HIV infection to black women. Currently, there exist very few scholarly works exploring the lives of black men who have sex with men and women that specifically address their own experiences living on the down low or how these men personally define what it means to be on the down low. In this article, we explore why black men who have sex with men and black men who have sex with men and women, including those who self-identify as gay, bisexual or as being on the down low, come to use the down low label and what it means to them to be on the down low.     

Interpreting the Butterfly Dream

This paper follows the tradition of treating Zhuangzi's Butterfly Dream episode as presenting a version of skepticism. However, unlike the prevalent interpretations within that tradition, it attempts to show that the skepticism conveyed in the episode is more radical than it has been conceived, such that the episode can be read as a skeptical response to Descartes’ refutation of skepticism based on the Cogito, ergo sum proof. The paper explains how the lack of commitment in Zhuangzi to the dubious assumption about ‘I’ that it necessarily refers to something existing to which Descartes seems to uncritically adhere allows Zhuangzi to doubt what for Descartes is absolutely indubitable: I exist.     

具体情绪及非依随反馈方式对自我妨碍的影响

该研究采用实验法考察了具体情绪以及非依随反馈方式对自我妨碍的影响。被试为104名大学生。结果表明：1）愉快组被试做出的决策型自我妨碍行为较少;恐惧组被试做出的回避型自我妨碍较多。2）两种非依随反馈方式对自我妨碍的影响没有显著差异。3）无论是决策型自我妨碍还是回避型自我妨碍,男生均高于女生。     

儿童特质推理中的信息利用

特质研究是心理理论框架中一个重要方面。儿童进行特质推理时对特质信息的利用,是考察其是否拥有完整特质概念的一个重要指标。综述以往研究可以看到在获得完整的特质概念之前,儿童倾向于运用到特质以外的其他信息做出跨特质范畴的推论,尤其是这些信息比特质信息更加具体明显时。文章概述了六个可能影响到儿童特质推理的信息:情境信息、行为频率、示例频率、效价信息、随意性信息、规则信息。在此基础上,对该领域的研究趋势作了展望。
