弱智儿童视觉图形辨认的实验研究

本研究探讨了不同智商水平的弱智儿童的视觉图形辨认能力的差异,并与同龄正常儿童作了比较。结果表明,智商在31-51,平均智商为41.6,均龄为11.7岁的弱智儿童,在图形以0.05秒速度的呈现条件下,平均辨认正确率为21.4%;在以0.01秒速度呈现的条件下,平均正确率为20.7%。智商在55-75,平均智商为62.0,均龄为10.2岁的弱智儿童,图形以0.05秒速度呈现时,平均辨认正确率为48.5%;在以0.01秒速度呈现时,平均正确率为45.0%。与同均龄的正常儿童比较,无论在哪一种呈现速度条件下,对图形辨认正确率均明显低于正常儿童。     

帛书《易传》四篇天人道德观析论

本文通过对帛书易传<二三子问>、<易之义>、<要>、<缪和、昭力>四篇的分析,认为帛传四篇为孔子<易>论,其中包涵着<论语>、<孔子集语>、传世本<易传>等反映孔子思想的传世文献所隐微罕见的天人道德观念;帛传四篇表现了孔子在涵括三代以至春秋新旧天人观念的基础上对于天人内涵的初步的哲学改造,反映了孔子将传统的主宰之天转化为道德之天、并将传统的主体对于形上存在的外在超越关系转化为内在超越关系的致思取向,从而凸显了孔子作为当时敏锐而深邃的思想家的形象;帛传四篇所涵具的孔子天人道德思想补足了三代天命德政观与思孟天道性命思想之间的逻辑缺环,是经由曾子(<天圆>)而达致<中庸>、郭店儒家简、<孟子>乃至传世本<易传>所体现的天道性命思想高峰的理论根据.

Maximum likelihood estimation of latent interaction effects with the LMS method

In the context of structural equation modeling, a general interaction model with multiple latent interaction effects is introduced. A stochastic analysis represents the nonnormal distribution of the joint indicator vector as a finite mixture of normal distributions. The Latent Moderated Structural Equations (LMS) approach is a new method developed for the analysis of the general interaction model that utilizes the mixture distribution and provides a ML estimation of model parameters by adapting the EM algorithm. The finite sample properties and the robustness of LMS are discussed. Finally, the applicability of the new method is illustrated by an empirical example. This research has been supported by a grant from the Deutsche Forschungsgemeinschaft, Germany, No. Mo 474/1 and Mo 474/2. The data for the empirical example have been provided by Andreas Thiele of the University of Frankfurt, Germany. The authors are indebted to an associate editor and to three anonymous reviewers ofPsychometrika whose comments and suggestions have been very helpful.     

Specific effects of acute moderate exercise on cognitive control

The main issue of this study was to determine whether cognitive control is affected by acute moderate exercise. Twelve participants [4 females (VO_{2 max} = 42 ml/kg/min) and 8 males (VO_{2 max} = 48 ml/kg/min)] performed a Simon task while cycling at a carefully controlled workload intensity corresponding to their individual ventilatory threshold. The distribution-analytical technique and the delta plot analysis [Ridderinkhof, K. R. (2002). Activation and suppression in conflict tasks: Empirical clarification through distributional analyses. In W. Prinz & B. Hommel (Eds.), Common mechanisms in perception and action. Attention and performance (Vol. 19, pp. 494–519). Oxford: Oxford University Press.] were used to assess the role of selective response inhibition in resolving response conflict. Results showed that cognitive processes appeared to be differently affected by acute moderate exercise. Reaction time results confirmed that performance is better (faster without change in accuracy) when the cognitive task is performed simultaneously with exercise. Between-trial adjustments (post-conflict and post-error) highlighted that cognitive control adjustments are also fully efficient during exercise. However, the effect of congruency (Simon effect) appeared to be more pronounced during exercise compared to rest which suggests that the response inhibition is deteriorated during exercise. The present findings suggest that acute moderate exercise differently affects some specific aspects of cognitive functions.     

Processing of color words activates color representations

Two experiments were conducted to investigate whether color representations are routinely activated when color words are processed. Congruency effects of colors and color words were observed in both directions. Lexical decisions on color words were faster when preceding colors matched the color named by the word. Color-discrimination responses were slowed down when preceding color words mismatched the test color even if no task had to be performed on these words. These findings are consistent with the experiential view of language comprehension according to which color perception and the comprehension of color words are based on overlapping representational resources.

读者追随目标信息建构情境模型

探讨文本阅读中读者追随目标焦点信息建构情境模型的过程。实验1采用“目标启动＋目标整合”的方式,探讨读者在显性焦点情况下的阅读是否会追随目标信息更新情境模型。实验2采用“目标启动＋目标未整合”的方式,探讨显性焦点下对目标信息进行的追随建构,是发生在目标焦点整合后还是在阅读进程中即时进行。实验2a运用动窗技术,实验2b则采用眼动技术来探讨这个问题。实验结果总的表明,在阅读过程中读者会追随目标焦点信息建构情境模型,并且这种建构是即时进行的     

篇章阅读的动态理解观和计算机模拟的应用

篇章阅读中信息加工的研究一直是文本心理学以及相关科学研究的热点问题。近几年,篇章阅读的动态理解观和计算机模型的影响力正逐步增大。与先前阅读加工观相比,动态理解观整合了阅读的即时加工和延时表征以及两者之间动态的相互关系,并试图捕捉篇章中的每一概念在整个阅读过程中不断变化的激活情况。利用计算机模型研究阅读加工则不像以往的研究方法都需要利用被试的实际阅读反应,在阅读理论的基础上编制的计算机模型能够模拟出人们阅读中的即时表现和阅读后的记忆内容,模拟的数据与行为学实验结果也非常一致     

项目反应时间的对数偏正态模型

近年来,项目反应时间数据的建模是心理和教育测量领域的热门方向之一。针对反应时间的对数正态模型和Box-Cox正态模型的不足,本文在van der Linden的分层模型框架下基于偏正态分布建立一个反应时间的对数线性模型,并成功给出模型参数估计的马尔科夫链蒙特卡罗（Markov Chain Monte Carlo, MCMC）算法。模拟研究和实例分析的结果均表明,与对数正态模型和Box-Cox正态模型相比,对数偏正态模型表现出更加优良的拟合效果,具有更强的灵活性和适用性。
