中学生写作文本形成能力的发展特点

从一所普通中学六个年级随机选取801名被试,使用自编测验研究了中学生写作文本形成能力的发展特点,结果发现：（1）中学生写作文本形成能力起点较高,初三年级是其基本形成的关键期;（2）中学生写作文本形成能力在高中阶段发展平缓;（3）中学生写作文本形成能力分维度的不同方面发展不均衡,较高水平方面受到认知加工容量、概括水平和抽象逻辑思维水平等心理因素的制约;（4）中学生写作文本形成能力存在性别差异,女生优于男生。     

人工类别学习的认知神经研究

基于类别学习包含类别归纳、分类和认知控制3个子过程的假设, 设计了人工类别学习的新任务, 利用高密度ERP技术并结合偶极子源分析, 从纵向和横向两个方面研究了人工类别学习的神经基础与机制。结果表明, 人工类别学习涉及前扣带回、前额叶皮质和内侧颞叶等关键脑区, 并在时间序列上显示了这些脑区扮演的不同作用。基于当前发现, 我们从时-空水平上讨论了的人工类别学习的认知神经机制。     

工作记忆与小学生文本产生、书写活动的关系

以小学三、六年级学生为被试,考察工作记忆与小学生文本产生、书写活动之间的关系。结果表明．工作记忆中的储存、加工功能对小学生写作的影响不同,储存功能主要与书写活动有关,加工功能主要与文本产生有关,储存与加工相对独立。随年级增长,小学生工作记忆的加工水平逐步提高。

文章标记效应的初步实验研究

探讨文章阅读过程中文章宏观标记与微观标记对文章不同类型信息保持的影响．包括两个实验。结果表明,文章宏观标记对文章主题信息的保持有显著的促进效应,而且,这种促进效应可以扩散到从属信息的保持上;文章微观标记对文章主题信息的保持无明显的促进效应,对被标记的文章具体信息的保持则有显著的促进效应。但不存在扩散效应。本研究结果初步表明,读者利用文章宏观标记建构文章主题的表征,并且以一种自上而下的方式指导文章信息的回忆;通过利用文章微观标记建构文章具体信息的表征,指导具体信息的回忆。     

Psychological Groups and Political Psychology: A Response to Huddy's "Critical Examination of Social Identity Theory"

In a recent article in this journal, Leonie Huddy (2001) asks whether the social identity approach developed by Tajfel, Turner, and their collaborators can "advance the study of identity within political science" (p. 128). She concludes that "various shortcomings and omissions in its research program" (p. 128) hinder the application of the approach to political phenomena. This paper presents a response to Huddy's evaluation of the social identity approach. Several aspects of her account of social identity work are challenged, especially her suggestion that it ignores subjective aspects of group membership. The interpretation of the minimal group paradigm is discussed in detail, as are issues of identity choice, salience, and variations in identity strength. The treatment of groups as process in social identity theory and self–categorization theory is given particular emphasis.     

Prediction Errors and Attention in the Presence and Absence of Feedback

ABSTRACT— Contemporary theories of learning typically assume that learning is driven by prediction errors—in other words, that we learn more when our predictions turn out to be incorrect than we do when our predictions are correct. Results from the recording of electrical brain activity suggest one mechanism by which this might happen; we seem to direct visual attention toward the likely causes of previous prediction errors. This can happen very rapidly—within less than 200 milliseconds of the error-causing object being presented. It is tempting to infer that if learning is driven by prediction errors, then little can be learned in the absence of feedback. Such a conclusion is unwarranted. In fact, the substantial learning that is sometimes the result of simple exposure to objects can also be explained by processes of directing attention toward the likely causes of previous prediction errors.     

项目诊断性在特征推理中作用的研究

该研究在Murphy等人2005年研究的基础上,探讨了项目诊断性对特征推理的影响。实验1探讨归类情况下,项目诊断性对特征推理的影响。实验2探讨不归类情况下,项目诊断性对特征推理的影响。实验结果表明,归类与否决定项目诊断性是否影响特征推理。在归类情况下,高低两种诊断性条件下的特征概率判断没有差异,表明归类情况下,项目诊断性不影响特征推理;在不归类的情况下,高低两种诊断性条件下的特征概率判断存在显著差异,表明不归类情况下,项目诊断性影响特征推理。     

消失文本条件下注视点右侧词对中文阅读影响的眼动研究

采用消失文本范式,考察在中文阅读过程中注视点右侧词对阅读的影响。实验一发现,若读者所注视的双字词及其右侧词在80ms后同时消失,则会对其正常阅读产生干扰。实验二排除了当前注视词消失可能存在的效应,即让右侧词在80ms后单独消失,结果仍发现会干扰正常阅读。另外,在两个实验中均发现了显著的词频效应。这些结果不仅支持眼动的认知控制模型,还证实注视点右侧词的加工对顺利阅读具有重要性。     

The role of social categorization and identity threat in the perception of migrants

This paper investigates how the categorization of migrant workers shapes their reception. In an experiment with Northern Irish Protestants we manipulated the representation of Poland to make the Catholicism of Polish migrants either more, or less, salient. Furthermore, judgements of Polish migrants were obtained under conditions designed to encourage participants to believe that sectarian conflict in Northern Ireland was either resolved, or still a strong feature of the present social landscape. Overall, results showed that when Poland's Catholicism was salient, participants were less welcoming of Polish migrants. Furthermore, this effect was mediated by increases in the level of symbolic threat participants believed the migrants posed to participants' (Protestant) community identity.
