韦氏儿童智力量表能否测量第3因子--WISC-CR的多元概化理论研究

本文针对WISC－CR的二因子和三因子模型,以201位6至7岁小学生为对象,运用多元概化理论的方法研究了其总信度和各亚因子的测量信度。研究发现：（1）二因子模型下各亚因子与总测验的测量信度都比较高。但当它被作为测量言语理解、知觉组织和抗干扰三个因子的量表时,第3个因子的信度过低,且不易得到改善。这表明不宜用它来测量抗干扰的能力;（2）该量表不宜作为标准参照性测验来使用,因为其测量信度无法得到保障,此外,文章还展示了评价一个成套测验总信度及其亚能力因子信度的MGT方法,这于心理测量学的发展是有价值的。     

睡眠剥夺对连续作业的影响

将18名青年被试随机分为三组,Sd21h、SD45h和SD69h,SD前后用内田—克莱佩林测试。结果为：(1)SD后组间比较,UK作业量、错误数、后期增减率各组之间有显著差异;订正数各组之间没有显著差异;(2)SD前后自身比较,各组UK总量、后一部分总量、错误数和后期增减率有显著差异;订正数无显著差异;SD21组前一部分总量有显著差异;而SD45和SD69组前一部分总量无显著差异。该结果表明,SD后警赏水平下降,在SD45小时后下降更为明显;UK测验中的后期增减率可较好地反映SD后警赏水平的变化。     

非流畅性对定向遗忘元认知判断的影响

目的:研究拟探讨知觉改变引起的难度和材料意义引起的真实难度导致的非流畅体验对元认知判断的影响;同时对比记住判断和遗忘判断的不同。方法:引入定向遗忘程序,让被试在"记住"条件下作学习判断,在"忘记"条件下作遗忘判断,考察两种不同难度对人们有意遗忘和识记能力的影响。结果:两种材料难度对预测判断和学习成绩有不同的影响,而且两个实验均表明学习判断值显著高于遗忘判断值。结论:知觉属性导致的表面难度引起的非流畅性不同于材料的真实难度引起的非流畅性体验,由真实难度引发的加工可能促使记忆更加深刻,同时,记住判断的准确性高于遗忘判断。     

Re-examining the Relationship Between Need for Cognition and Creativity: Predicting Creative Problem Solving Across Multiple Domains

Prior studies have demonstrated inconsistent findings with regard to the relationship between need for cognition and creativity. In our study, measurement issues were explored as a potential source of these inconsistencies. Structural equation modeling techniques were used to examine the factor structure underlying the 18-item need for cognition scale in three independent samples drawn from three prior studies. In addition, the relationships between need for cognition and the quality, originality, and elegance of creative problem solutions across multiple domains of performance were analyzed. Across all 3 samples, the bifactor model fit the data better than the 2-factor and 1-factor need for cognition models. After controlling for method-specific variance, the trait factor of the bifactor model showed consistently positive relationships with all 3 facets of creative performance and showed stronger relationships with these facets than the composite score results reported in prior studies. Implications for research and practice are discussed.     

Assessment and Diagnosis of Autism Spectrum Disorder in Hanoi,Vietnam

For individuals with autism spectrum disorder (ASD), early and accurate diagnosis enables early intervention, which leads to improved quality of life. The diagnostic label of ASD has only been recognized in Vietnam since 2000 and the number of children who have been diagnosed has increased dramatically. However, there is limited understanding about the condition. This article aims to describe the current assessment and diagnostic practices in Hanoi, Vietnam, a low resource setting. Data for this article came from in-depth interviews with parents of children with ASD and service providers, and observation at health clinics and early intervention centers that provide ASD assessment during field work from July 2011 to May 2012. This study reveals that although there is some improvement in assessment services, parents still face a number of challenges in accessing quality assessment and diagnosis of ASD in Vietnam. These include rushed and perfunctory assessment; a lack of clinical guidelines for assessment; limited communication among health professionals in assessment teams, and between professionals and parents of children with ASD. Public awareness-raising of the signs of autism, capacity building for professionals, development of practical and contextual appropriate assessment protocols are needed to enhance the accessibility and quality of assessment services.     

语言,语义,语言表征,心理理论--从语言获得建构理论谈心理理论和语言能力的关系

语言获得建构论认为儿童利用社会和一般的认知技能进行范畴化。通过主动的用法建构获得语言符号系统。通过大量研究分析推断：儿童心理理论的发展是儿童社会认知概念系统发展和语言表征发展的结果。通过概念系统发展和语言表征以及语言功能性发展的分析,有助于理解语言能力和心理理论的关系。     

中药复方对铅染毒大鼠学习记忆障碍的改善作用

应用行为药理学方法研究铅对大鼠学习记忆影响的可能机制,并观察中药复方（驱铅灵）对铅染毒大鼠学习记忆障碍的改善效果。结果：（1）各染毒组大鼠Morris（第一、二、三、五、七轮）测试潜伏期显著延长;记忆保持百分率显著下降。（2）治疗后中药组的大鼠Morris水迷宫第2、3轮测试潜伏期显著短于阳性对照组,记忆保持率显著大于阳性对照组。（4）EDTA组和中药组。结论：中药复方对铅染毒大鼠学习记忆障碍具有良好的改善作用。     

阴阳五行说的发展演变与中华民族思维方式的基本形成

阴阳五行说的形成经历了一个漫长的历史时期,是我国古代农业文明的结晶,对于秦汉及其以后的封建社会的发展影响深远,成为封建统治者建立政权的历史哲学。与西方文明的发展路径相比有所不同的是,阴阳五行说所体现出的关联思维方式,是中国人的思想律,是古人对于天人之际这一问题加以思考所得出的结论。这一学说在《内经》医学哲学的思想框架中被采纳,并在现实的医学实践中被广泛运用,从而将精神与身体有机地结合在一起。     

实在论、观念论与语义学:现代英美巴门尼德解释的三条进路

现代英美关于巴门尼德哲学的解释可谓五花八门,如何梳理和鉴别这些解释是进一步研究的前提条件.关键是,我们该如何确定我们自己借以鉴别这诸多解释所依据的视向呢?因此,我们有理由将推演性重构的"进路"或"出发点",而非"结论"作为我们梳理现代英美巴门尼德解释谱系的主导视向.     

阅读能力个体差异的遗传基础—— 双生子研究的元分析

阅读能力的个体差异来源是行为遗传学的研究焦点之一。文章通过对80个阅读双生子研究的元分析发现：(1)遗传对阅读及其加工过程、基本认知技能具有中等强度影响; (2)不同阅读加工成分既受到共同遗传因素的作用, 又同时受到特异遗传因素的影响。(3)阅读与一般认知能力、数学能力在遗传上存在中等强度相关。这些结果表明了双生子研究对探索阅读的遗传机制具有分子遗传学所不可替代的价值, 文章还提出了如提升行为表型的测查质量等对未来研究的具体建议。
