初中生有无插图课文的眼动过程研究

本研究使用美国应用科学实验室(ASL)生产的4200R型眼动仪,采用2×2的二因素混合设计,对30名初中二年级学生阅读有无插图且难易不同的课文的阅读理解指标和眼动指标进行考察,结果表明(1)初中生阅读有无插图课文的成绩、时间和速度等阅读理解指标,插图课文显著优于无图课文,插图对课文的阅读理解整合具有明显地促进作用;而且注视次数和回视次数等眼动指标插图课文亦显著优于无图课文.(2)初中生阅读易课文的成绩、时间和速度等阅读理解指标不仅显著优于难课文,而且注视次数、眼跳距离和回视次数等眼动指标易课文亦显著优于难课文.     

英语学习不良儿童语音意识假词拼读与单词认知能力的关系研究

本研究探讨了英语学习不良儿童语音技能一语音意识与词汇到达的发展水平及这两项语音技能与其单词认知能力间关系。结果发现,英语学习不良儿童在假词拼读能力发展上存在缺陷．而在语音意识能力的发展方面却表现正常。在对儿童的单词认知能力进行预测时,语音意识和假词拼读能力是较好的效标。     

亚词汇水平加工的本质:形旁的语音激活

该研究利用启动命名技术,探讨了汉字加工时是否存在着形旁的语音激活。把含有独立成字的形旁的合体字（如“躲”）作为启动字,与形旁同音的字（如“深”）作为目标字。结果发现,当合体字是低频字时,目标字的命名速度显著加快。高频合体字则没有此效应。集合Ｚｈｏｕ和Ｍａｒｓｌｅｎ－Ｗｉｌｓｏｎ关于声旁语义激活的研究,该文得出结论说,汉字亚同汇水平的加工与词汇水平的加工表现一样,两者之间并无本质性的差别。     

Examining the core: Relations among reading curricula, poverty, and first through third grade reading achievement

Policy changes at the federal and state level are endeavoring to improve student achievement at schools serving children from lower-SES homes. One important strategy is the focus on using evidence-based core reading curricula to provide a consistent framework for instruction across schools. However, rarely have these curricula undergone rigorous comparative testing. Therefore, the purpose of this study was to compare the effects of six core reading curricula on oral reading fluency growth, while appraising whether these effects differ by grade level and for children living in lower socioeconomic (SES) households. Over 30,000 students in first through third grade Florida Reading First classrooms comprise this academically and economically diverse cross-sectional. Hierarchical Linear Modeling was used to model latent growth curves for students' reading fluency scores over the school year. Growth curves revealed differences across curricula as well as between students of lower and higher SES, suggesting that reading fluency growth trajectories for curricula varied depending on student SES and grade level. Findings indicate that while there are similarities among curricula, they sometimes differ in their ability to promote reading skill growth. Differences by grade level and SES were also detected. However, many of these differences were small. Implications for the use of curriculum as a conduit for improving reading instruction are discussed.     

Brain activation on pre-reading tasks reveals at-risk status for dyslexia in 6-year-old children

In this fMRI-study, 6-year-old children considered at risk for dyslexia were compared with an age-/gender-matched control group for differences in brain activation when presented with visual stimuli differing in demands for literacy processing. Stimuli were nameable pictures, brand logos familiar to children, and written words - these were either regularly spelled using early-acquired rules ("alphabetic") or more complex ("orthographic"). Brain responses distinguished between the presentation conditions, as a function of group, within many cortical areas. Activation in the alphabetic and orthographic conditions in the left angular gyrus correlated with individual at-risk index scores, and activation in inferior occipito-temporal regions further indicated differential activation for the two groups related to orthographic processing, especially. Since similar patterns are reported in adult dyslexics when processing written words, it appears that sensitivity to the cortical differentiation of reading networks is established prior to formal literacy training.     

Scope Processing in Chinese

The standard view maintains that quantifier scope interpretation results from an interaction between different modules: the syntax, the semantics as well as the pragmatics. Thus, by examining the mechanism of quantifier scope interpretation, we will certainly gain some insight into how these different modules interact with one another. To observe it, two experiments, an offline judgment task and an eye-tracking experiment, were conducted to investigate the interpretation of doubly quantified sentences in Chinese, like Mei-ge qiangdao dou qiang-le yi-ge yinhang (Every robber robbed a bank). According to current literature, doubly quantified sentences in Chinese like the above are unambiguous, which can only be interpreted as ‘for every robber x, there is a bank y, such that x robbed y–surface scope reading), contrary to their ambiguous English counterparts, which also allow the interpretation that ‘there is a bank y, such that for every robber x, x robbed y–inverse scope reading). Specifically, three questions were examined, that is, (i) What is the initial reading of doubly quantified sentences in Chinese? (ii) Whether inverse scope interpretation can be available if appropriate contexts are provided? (iii) What are the processing time courses engaged in quantifier scope interpretation? The results showed that (i) Initially, the language processor computes the surface scope representation and the inverse scope representation in parallel, thus, doubly quantified sentences in Chinese are ambiguous; (ii) The discourse information is not employed in initial processing of relative scope, it serves to evaluate the two representations in reanalysis; (iii) The lexical information of verbs affects their scope-taking patterns. We suggest that these findings provide evidence for the Modular Model, one of the major contenders in the literature on sentence processing.     

不同的拼音教学方式对幼儿拼音水平及汉语语音意识发展的影响

本研究用纵向实验的方法考察了分享阅读(故事教学)和传统教学(字母教学)两种拼音教学方式对幼儿园中班儿童的拼音水平和汉语语音意识发展的影响。研究结果表明:(1)相对于无拼音教学组,两种形式的拼音教学均可以显著提高幼儿的字母知识,但分享阅读拼音教学对幼儿字母知识的促进作用更大。(2)分享阅读的拼音教学可以显著提高幼儿的拼读能力,而传统教学对幼儿的拼读能力基本没有促进。(3)分享阅读的拼音教学对幼儿的首音、韵脚和声调意识的发展有显著的促进作用,对幼儿自然发展起来的音节意识的影响很小;传统教学对幼儿的语音意识基本没有促进。     

中文阅读中因果与转折关系理解差异的实验研究

采用移动窗口阅读技术和探测技术探讨大学生中文阅读过程中对因果与转折关系的理解差异。实验一在句子层面考察因果和转折关系的理解差异,结果发现被试阅读转折句的时间显著长于因果句,但对两种句子中探测词的反应时没有差异。实验二运用探测技术从篇章层面进一步探讨两种关系的理解差异。结果发现,转折关系条件下被试对探测词的反应时显著慢于因果关系条件下。实验结果表明,无论在句子层面还是在篇章层面,被试对转折关系的表征都难于因果关系的表征。     

汉字阅读的联结主义模型

汉字与英语词汇阅读受到相同统计属性的影响,表现出阅读加工的普遍性,汉字独特的形-音对应关系又体现出阅读的语言特异性。模型1建构与英文阅读模型完全相同的计算机模型,设计汉字的字形与语音表征方案,成功模拟出汉字阅读的规则性、一致性效应及其与频率的交互作用,得到与行为实验相同的结果模式;模型2改变声旁独立成字时的字形表征,结果规则性效应消失。模拟结果一方面表明汉字与英语词汇阅读可能具有普遍的加工机制,都是对输入语料的形-音对应关系统计学习的结果;另一方面表明输入语料的不同统计属性可能是汉字阅读的语言特异性来源     

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
