中小学生阅读不同配图课文的眼动研究

使用ASL-4200R型眼动仪,采用3×2×2的三因素混合设计,对77名中小学生阅读不同配图课文进行了考察。结果表明:(1)中小学生阅读不同配图难度课文的阅读成绩、阅读时间等阅读理解指标,以及注视频率、注视点持续时间和眼跳距离等眼动指标具有明显的年龄特征;(2)中小学生阅读不同配图课文的阅读成绩、阅读时间和阅读速度等阅读理解指标,以及注视次数和回视次数等眼动指标具有显著差异,示意图组显著优于实景图组;(3)中小学生阅读不同难度课文的注视频率和回视次数对阅读过程有非常显著的影响,易课文显著优于难课文。     

不同认知风格小学生的外显和内隐记忆发展研究

以小学三年级和五年级146名学生为被试,采用2(年级:三年级、五年级)×2(图片类型:具体图片、抽象图片)×2(认知风格:冲动型、反省型)混合设计,依据Gruppuso等人提出的单一测验加工分离程序的范式,对不同认知风格小学生的外显记忆和内隐记忆发展进行了探讨。结果发现.外显记忆具有明显的年龄特征,内隐记忆则无。认知风格对外显记忆未表现出显著的影响。五年级反省型被试的内隐记忆成绩显著高于同年级冲动型被试的成绩。     

Child-care structure-->process-->outcome: direct and indirect effects of child-care quality on young children's development

With data from the NICHD Study of Early Child Care, we used structural equation modeling to test paths from structural indicators of child-care quality, specifically caregiver training and child-staff ratio, through a process indicator to child outcomes. There were three main findings: (a) Quality of maternal caregiving was the strongest predictor of cognitive competence, as well as caregivers' ratings of social competence; (b) quality of nonmaternal caregiving was associated with cognitive competence and caregivers' ratings of social competence; and (c) there was a mediated path from both caregiver training and child-staff ratio through quality of nonmaternal caregiving to cognitive competence, as well as to caregivers' ratings of social competence, that was not accounted for entirely by family variables. These findings provide empirical support for policies that improve state regulations for caregiver training and child-staff ratios.     

隐含因果关系影响代词解决的研究进展

动词的隐含因果关系会影响代词的解决,对阅读因果复句的研究表明,隐含因果关系发生作用的时程可能在阅读过程中即时发生,也可能在读者读完整个句子后才发生作用,对此有焦点假设、整合假设和混合假设.不同的研究者支持不同的假设.未来研究的方向将进一步探讨不同的动词、不同的读者对隐含因果关系发生作用时程的影响.

言几存义开物成务——纪念《周易研究》创刊暨山东大学易学与中国古代哲学研究中心成立20周年

2008年是我国改革开放30周年,恰巧又是<周易研究>学刊创办20周年和山东大学周易研究中心(现易学与中国古代哲学研究中心)成立20周年. 1987年12月5日,经国家教委批准,当时的山东大学哲学系周易研究室以山东省政府划拨的3万元经费,在当时山东省接兵站召开了建国后"首届国际周易学术研讨会",共有6个国家的200余名代表参加.     

医学模式的转变与胃食管反流病的思考

胃食管反流病（GERD）是消化科门诊最常见的疾病之一,具有慢性复发性倾向,严重影响人们的生活质量。目前认为本病是一种多因素的心身疾病,随着传统生物医学模式向生物-心理-社会医学模式的转变,要求我们要自觉地运用辩证唯物主义观点,从系统论出发,应用发展的观点,注重医学模式的转变,审慎制定治疗方案。     

The limitations of "vulnerability" as a protection for human research participants

Vulnerability is one of the least examined concepts in research ethics. Vulnerability was linked in the Belmont Report to questions of justice in the selection of subjects. Regulations and policy documents regarding the ethical conduct of research have focused on vulnerability in terms of limitations of the capacity to provide informed consent. Other interpretations of vulnerability have emphasized unequal power relationships between politically and economically disadvantaged groups and investigators or sponsors. So many groups are now considered to be vulnerable in the context of research, particularly international research, that the concept has lost force. In addition, classifying groups as vulnerable not only stereotypes them, but also may not reliably protect many individuals from harm. Certain individuals require ongoing protections of the kind already established in law and regulation, but attention must also be focused on characteristics of the research protocol and environment that present ethical challenges.     

Pathways to reading: the role of oral language in the transition to reading

What is the role of oral language in reading competence during the transition to school? Is oral language in preschool best conceptualized as vocabulary knowledge or as more comprehensive language including grammar, vocabulary, and semantics? These questions were examined longitudinally using 1,137 children from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development. Children were followed from age 3 through 3rd grade, and the results suggest that oral language conceptualized broadly plays both a direct and an indirect role in word recognition during the transition to school and serves as a better foundation for early reading skill than does vocabulary alone. Implications of these findings are discussed in terms of both theoretical models of early reading and practical implications for policy and assessment.
