发展性阅读障碍的理论及眼动研究

关于发展性阅读障碍,国外研究者,基于认知和生物因素,先后提出了语音缺陷论、小脑缺陷论、一般性大细胞功能障碍论等对发展性阅读障碍进行解释,并考察了患者的眼动特征,提出了有效的诊治方法。目前,汉语发展性阅读障碍研究主要局限在语音和正字法领域,也涉及局部脑区的功能缺陷,但还未从多角度测查其成因,如眼动。这里,在理论梳理的基础上,系统探讨了发展性阅读障碍者的眼动特征,如注视时间、注视次数、眼跳、回视等,及视觉加工的眼动机制     

IRT中最小化χ2/EM参数估计方法

对IRT的双参数Logistic模型（2PLM）中未知参数估计问题,给出了一个新的估计方法――最小化χ2/EM估计。新方法在充分考虑项目反应理论(IRT)与经典测量理论(CTT)之间的差异的前提下,从统计计算的角度改进了Berkson的最小化χ2估计,取消了Berkson实施最小化χ2估计时需要已知能力参数的不合实际的前提,扩大了应用范围。实验结果表明新方法能力参数的估计结果与BILOG相比,精确度要高,且当样本容量超过2000时,项目参数的估计结果也优于BILOG。实验还表明新方法稳健性好     

社会认知的神经基础

人类的社会技能高于其它任何动物,能够形成对社会环境的高级表征,并能利用这些表征进行十分灵活的推理判断。但是社会认知的神经基础目前仍不十分明了。来自于人类和其它灵长类动物的研究已经发现有一些脑结构（如杏仁核、前额叶、颞上沟、扣带前回等）在社会认知中起着特殊重要的作用。此外,越来越多的研究表明其它一些脑区结构（如右侧躯体体感区、岛叶、基底节、白质等）也共同参与社会认知加工过程。文章对近年来关于社会认知的神经基础研究做了较为详细的综述。     

论先秦法家的人性理论与领导心理思想

先秦法家对人性认识的基本点是“性本恶”。其思想内容有 :人的需要是推动其行为发展的动力 ,是管理的出发点 ;在追求满足个人欲望的时候 ,人们会违背礼仪和伦常 ;人的欲望是多种多样的 ,而对利益的追求是根本的驱动力和唯一目的 ;人性的善或恶是可以诱导的 ,管理者如何倡导是关键。法家将法、术、势结合起来 ,三位一体 ,形成了法家独有领导心理思想 ,并认为只有善于运用法、术、势的人 ,才可能成为理想的管理者“明君     

互联网——心理学研究的新工具

互联网作为一种新的工具,在心理学研究中得到越来越多的使用。文章介绍了基于互联网的心理学研究的历史和现状,并分析了这种新研究工具的优点,如更高的效度,多样化的被试,操作更方便更高效,费用更低廉等。同时也客观地指出了新研究工具的局限性,如并不是所有的心理学研究都可以在互联网上实现,控制不够严格等。但是作为一种新的研究工具,互联网应该得到心理学工作者更多的重视。     

系列包含的项目数、项目之间的间隔时间与系列位置效应

以中国汉字为材料,考察系列包含的项目数、项目之间的时间间隔与系列位置曲线不同部分记忆性质分化的关系。结果表明,(1)提取过程的重要性。(2)在包含11个项目、并且项目之间的时间间隔为400毫秒的系列中,系列位置曲线的首因部分表现为联想记忆的性质,是依赖于线索的提取;近因部分表现为绝对记忆的性质,是依赖于记忆痕迹的提取。(3)系列位置曲线不同部分记忆性质的分化,于系列包含的项目数和项目之间的间隔时间有关,结果体现出这两个因素的交互作用。     

Blood is thicker: moral spillover effects based on kinship

Three empirical studies document the intuitive spillover of moral taint from a person who engages in immoral acts to another individual who is related by ties of blood kinship. In Study 1, participants were more likely to recommend that the biological grandchild of a wrongdoer, compared to a non-biological grandchild, help the descendants of his grandfather's victims. In Study 2, participants were more willing to hold two long-lost identical twins in custody for a crime committed by one twin than to hold two perfect look-alikes for a crime committed by one look-alike. Study 3 provides direct evidence that spillover effects based on blood kinship are manifested in an intuitive sense of moral taint.     

Neural correlates of comprehension and production of nouns and verbs in Chinese

This paper reports a conjunction analysis between semantic relatedness judgment and semantic associate generation of Chinese nouns and verbs with concrete or abstract meanings. The results revealed a verb-specific task-independent region in LpSTG&MTG, and task-dependent activation in a left frontal region in semantic judgment and the left SMG in semantic associate production. The observation of word class effects converged on Yu, Law, Han, Zhu, and Bi (2011), but contrasted with null findings in previous reports using a lexical decision task. While word class effects in the left posterior temporal cortices have been described in previous studies of languages with rich inflectional morphology, the significance of this study lies in its demonstration of the effects in these regions in a language known to have little inflectional morphology. In other words, differential neural responses to nouns and verbs can be observed without confounding from morphosyntactic operations or contrasts between actions and objects.     

Measurement invariance of WISC-IV across normative and clinical samples

Measurement invariance of the WISC-IV second-order factorial structure between normative and clinical samples was investigated using WISC-IV core subtests and a total of 1100 children aged 6-16. Multi-group higher order analysis of mean and covariance structure (MG-MACS) models were used to analyze these data. Results supported measurement invariance. Only Coding and Comprehension subtest intercepts varied slightly between groups. The hypothesized WISC-IV factor model described the data well. Factor patterns, first- and second-order factor loadings, intercepts, residual variances of measured subtests, and disturbances of first-order factors of the WISC-IV were generally invariant. Results suggested that WISC-IV index scores and subtests have the same meaning for children in both normative and clinical groups.     

Unconscious structural knowledge of tonal symmetry: Tang poetry redefines limits of implicit learning

The study aims to help characterize the sort of structures about which people can acquire unconscious knowledge. It is already well established that people can implicitly learn n-grams (chunks) and also repetition patterns. We explore the acquisition of unconscious structural knowledge of symmetry. Chinese Tang poetry uses a specific sort of mirror symmetry, an inversion rule with respect to the tones of characters in successive lines of verse. We show, using artificial poetry to control both n-gram structure and repetition patterns, that people can implicitly learn to discriminate inversions from non-inversions, presenting a challenge to existing models of implicit learning.
