汉字字形输出过程中儿童的汉字结构意识

本研究通过控制汉字声旁与形旁的结构特征,采用听写纸笔测验考察了小学四年级儿童在汉字字形输出过程中的汉字结构意识.结果发现汉字声旁的规则性与形旁语义透明度都直接影响听写的正确率与错误率;在这种任务条件下,声旁的规则性与形旁语义透明度相互作用;阅读水平低的儿童比阅读水平高的儿童产生更多的同音替代错误.文章从听写条件下汉字的加工与儿童词汇表征的角度探讨了这些结果的理论含义.     

儿童汉字读音声旁一致性意识的发展

采用同音判断的方法,考察儿童对汉字读音声旁一致性意识的发展。一个熟悉字和一个不熟悉字共用同一个声旁,该声旁在提示整字发音时可以是一致的,即包含此声旁的所有汉字都发音相同,也可以是不一致的。要求儿童猜测不熟悉字的读音,作出它与熟悉字“是”、“否”同音的判断。结果发现,儿童很早就意识到汉字的结构以及声旁和形旁在表音、表义功能上的分工。随着年级的升高,声旁一致性对猜测不熟悉汉字读音的影响增强。小学四年级语文能力较高的儿童已经开始意识到声旁的一致性;六年级儿童总体上说来已发展了一致性意识。初二年级的学生发展了声旁一致性意识,且没有能力差异。大学生的声旁一致性意识最强。     

三、五年级儿童形声字识别中形旁和声旁家族效应

采用2（年级）×2（声旁家族大小）×2（形旁家族大小）三因素混合实验设计,在形声字识别中考察了三、五年级儿童的形旁和声旁家族效应。结果仅在三年级中发现了显著的形旁家族大小效应,而五年级中却没有发现。但两个年级中形旁和声旁家族的交互作用均显著。进一步分析发现在声旁处于大家族时,形旁也处于大家族时,三、五年级儿童的反应时更快。此结果说明声旁和形旁家族共同影响形声字识别,但在三年级儿童中,形旁家族效应可以不依赖于声旁家族单独发挥作用,五年级儿童中却没有独立的形旁家族效应。     

二、三和五年级儿童对形旁语义的加工

结合启动范式和汉字判断任务,通过操纵目标字语义透明度,在汉字阅读过程探查了二、三、五年级儿童对形旁语义的加工。采用 3×2×2 混合实验设计,自变量为被试类型（小学二、三、五年级儿童）、启动字类型（字形相关 vs. 无关）和目标字类型（透明字 vs. 模糊字）。结果发现启动字类型、目标字类型和年级三者交互作用显著。随后分析在三五年级儿童中发现了显著的独立于字形的形旁语义启动效应,启动字中的共享形旁对模糊字的识别产生了更大的抑制作用,而在二年级儿童中并没有发现这种效应。说明形旁语义在儿童的心理词典中存在独立表征,可以被激活并促进儿童对汉字的识别,但是需要儿童的阅读理解能力发展到一定程度。     

小学生字词识别与语言技能、工作记忆关系研究

本研究采用注音任务、语言任务、再认方法探讨了小学生字词识别与语言技能、工作记忆的关系和影响小学生字词识别的因素。发现：(1)字词识别与语言技能、工作记忆在2、4年级相关均显著;6年级学生字词识别与语言技能的形旁及工作记忆相关不显著,但与语言技能其它维度相关显著(2)预测小学生字词识别发展的主要因素随年级升高而变化。预测2年级学生字词识别的重要指标是语音的音节、字形的形旁与工作记忆;4年级是语音的音节、字形的声旁、句法与工作记忆;6年级是语音的声韵、字形的声旁与语义。     

语素意识对学前儿童言语技能发展的预测作用：追踪研究的证据

为探讨词素意识、同形语素意识和形旁意识等不同层面语素意识对汉语儿童口语词汇、汉字识别和阅读理解能力发展的预测作用,本研究对75名学前儿童进行了一年半的追踪,结果发现:(1)学前儿童的语素意识和言语技能随时间均有显著增长。(2)在控制了因变量的自回归效应后,同形语素意识对一年半后的口语词汇成绩仍有显著的预测作用;词素意识能显著预测一年半后的汉字识别成绩;词素意识和形旁意识是儿童一年半后阅读理解成绩变异的重要解释变量。这表明语素意识对于学前儿童语言技能的发展具有重要的预测作用。     

小学儿童英语正字法技能的发展及其在单词阅读中的作用

为系统探讨正字法技能不同成分的发展特点及其在英语单词阅读中的作用,对小学一、三、五年级共110名儿童施测英语正字法规则意识、正字法模式建构技能、正字法编码技能、单词阅读以及一般认知能力和英语语音意识测验。结果表明：（1）汉语儿童的英语正字法技能各成分随年级显著增长,各成分间及其与一般认知技能、语音意识的关系存在年级差异;（2）控制年龄、一般认知能力和语音意识后,正字法技能在三、五年级仍对单词阅读有显著的独立解释作用,且其独立贡献率高于语音意识;（3）进一步控制其他正字法技能成分后,正字法规则意识以正字法模式建构技能为完全中介间接地作用于单词阅读,正字法模式建构技能在三、五年级都仍对单词阅读有显著的独立解释作用,正字法编码技能在五年级中能显著地独立解释单词阅读的部分变异。     

声旁部分信息在儿童学习和记忆汉字中的作用

采用类似课堂教学的学习－测验任务,通过3个实验探讨了声旁提供的部分读音信息在儿童学习和记忆汉字中的作用。被试来自北京市两所小学260名四年级学生。实验中要求学生学习和记忆3种生字：（1）声旁提供汉字读音的全部信息,如规则一致字;（2）声旁提供汉字读音的部分信息,如声调不同字或声母不同字;（3）声旁不提供汉字读音的信息,如声旁不知字。要求学生学习所有的字一遍后回忆生字的读音,共学习3遍。实验发现,儿童学习和记忆汉字的正确率随声旁提供的整字读音信息不同而不同：当声旁提供全部信息时正确率最高,当声旁提供部分信息时其次,当声旁没有提供信息时最低;而且声旁提供的部分信息越多,正确率越高。结果表明,儿童对声旁提供的部分读音信息敏感,发展声旁意识对学习和记忆汉字有积极作用     

书面字形在汉语低年级儿童口语词汇学习中的作用

采用配对联想学习范式, 通过2个实验, 系统考察了书面字形在汉语低年级儿童口语词汇学习中的作用。实验一以40名二年级学生为研究对象, 控制了假字的形旁透明度, 操纵了声旁的规则性, 要求儿童分别在规则字、不规则字和无字形条件下学习4个新异物体的名称, 结果发现呈现不规则汉字阻碍了儿童口语词汇的学习;实验二以27名一年级学生为研究对象, 采用相同的配对联想学习范式, 同时操纵了假字的声旁规则性和形旁透明度, 再次发现了不规则汉字的阻碍效应, 并且发现透明形旁对口语词汇学习的促进作用。整个研究表明, 书面字形在汉语儿童口语词汇学习中具有重要作用, 这对今后的教学实践和理论研究都具有重要启示意义。     

小学一年级阅读流畅性对二、三年级阅读理解的预测

采用追踪研究考察了124名小学一年级儿童的阅读流畅性对其二、三年级阅读理解的影响。结果发现,在控制了性别、家庭社会经济地位、推理能力、汉字识别、口语词汇及多种阅读相关认知技能之后,儿童一年级时的字词流畅性可以预期其二、三年级时的阅读理解水平,句子流畅性对二年级时阅读理解的变异有独特解释作用,但对三年级时阅读理解的变异没有显著的解释作用。相对于句子流畅性,字词流畅性在小学低年级阶段对阅读理解的贡献更大。     

The relationship between morphological awareness and reading comprehension in Spanish‐speaking children

In the last decades, a series of studies has explored the role of morphological awareness on reading comprehension. Path analysis studies performed in English have shown that morphological awareness benefits reading comprehension both directly and indirectly, through word decoding. This issue has seldom been explored in Spanish. The aim of this study was to replicate in Spanish the results previously found in English. We used path analysis to assess three alternative models of the relationship between morphological awareness, word decoding and reading comprehension in 4th grade Spanish‐speaking children. Contrary to English, we found that morphological awareness benefits reading comprehension only directly. We conclude that in Spanish, in which accurate and fluent pronunciation of written words can be achieved through grapheme‐to‐phoneme conversion rules, morphological awareness does not help the correct pronunciation of words. Thus, morphological awareness is not relevant for word decoding in Spanish but is related to reading comprehension since this type of morphological knowledge provides access to the semantic and syntactic information of new words.     

Retrieval practice improves learning in children with diverse visual word recognition skills

ABSTRACT

A large body of research shows that performing tests is more beneficial for the retention of studied materials than restudying those materials, a phenomenon termed “testing-effect”. A contemporary debate on the testing effect literature concerns whether the benefits of tests are equivalent for individuals with different cognitive skills, as the capacity to decode written words, for example. In the current study, we approached this issue in two experiments by examining whether testing is equally beneficial for children with diverse visual word decoding skills. To achieve this goal, we recruited sixth and fourth grade children (experiments 1 and 2, respectively) and administered a reading aloud task to assess their visual word recognition skills, and administered a memory task about an encyclopedic text to promote the testing effect. Memory for the restudied/tested contents of the encyclopedic text were probed after a seven-day interval, and although children from both experiments showed robust testing effects, such effects were not associated with their visual word decoding skills. These findings suggest that children with diverse word decoding skills can be benefited by retrieval practice.     

Italian developmental dyslexic and proficient readers: where are the differences?

Italian dyslexic children are characterized by a pervasive reading speed deficit, with relatively preserved accuracy. This pattern has been associated with predominant use of the nonlexical reading procedure. However, there is no evidence of a deficit in the lexical route of Italian dyslexics. We investigated both lexical and nonlexical reading procedures in dyslexic children through two marker effects, namely, the word frequency effect and the effect of contextual grapheme-to-phoneme conversion rules. Although dyslexics were slower and less accurate than controls, they were affected by word frequency, grapheme contextuality, and their interaction in a similar manner as average readers. These results show the use of lexical reading in Italian dyslexics, and refute the claim of a deficit in whole-word processing with consequent over-reliance on the nonlexical route.     

A comparison of word recognition processes in dyslexic and normal readers at two reading-age levels

This study addressed the question of whether dyslexic children use qualitatively different word identification processes as compared to normal readers at the same stage of reading acquisition. Fifty-two dyslexic children and reading-age matched normal readers were required to pronounce words and pseudowords designed to tap several word recognition and decoding processes. Performance profiles were compared for the two reading groups at two reading ages. Although an invariant acquisition sequence was observed across reading groups, differences in level of performance between dyslexics and reading-age controls varied as a function of reading age. The performance of the more advanced dyslexics was virtually indistinguishable from normal readers on all measures. In contrast, the younger reading age dyslexics differed from normal readers on several measures of spelling-sound correspondences. However, no reading group differences were observed on measures of word recognition. The results indicated that dyslexics and normal readers at the same reading age use essentially the same processes to recognize words, but may differ in knowledge of correspondence rules.     

语音意识的不同成分在汉语儿童英语阅读学习中的作用

研究一测查了74名小学三、五年级儿童辨别、删除汉语和英语音节、首音-韵脚、音位等不同语音成分的能力以及英语单词阅读,考察语音意识不同成分与英语阅读学习的关系及母语语音意识的作用途径.研究二测查了83名英语阅读较差和73名英语阅读一般及以上儿童的英语语音删除和单词认读能力,考察阅读水平对于语音意识作用的调节效应.结果表明:(1)英语首音-韵脚意识对英语阅读具有显著的独立贡献;(2)汉语首音-韵脚意识和声调意识分别对英语单词认读和假词拼读具有显著的独立贡献,二者通过英语首音-韵脚意识的中介发挥作用;(3)阅读水平具有显著的调节作用.首音-韵脚意识是正常儿童阅读的有效预测变量,而音节意识是低水平儿童阅读的有效预测变量.上述结果与有关语音意识各成分在英语为母语儿童阅读学习中作用的研究结果不同,提示第二语言的学习具有特殊性,母语经验影响着个体第二语言学习的过程.     

Phonological decoding or direct access? Regularity effects in lexical decisions of Grade 3 and 4 children

Learning to read fluently involves moving from an effortful phonological decoding strategy to automatic recognition of familiar words. However, little is known about the timing of this transition, or the extent to which children continue to be influenced by phonological factors when recognizing words even as they progress in reading. We explored this question by examining regularity effects in a lexical decision task, as opposed to the more traditionally used reading-aloud task. Children in Grades 3 and 4 made go/no-go lexical decisions on high- and low-frequency regular and irregular words that had been matched for consistency. The children showed regularity effects in their accuracy for low-frequency words, indicating that they were using phonological decoding strategies to recognize unfamiliar words. The size of this effect was correlated with measures of reading ability. However, we found no regularity effects on accuracy for high-frequency words or on response times for either word type, suggesting that even 8-year-old children are already relying predominantly on a direct lexical strategy in their silent reading of familiar words.     

Poor reading comprehension despite fast word decoding in children with hydrocephalus

Children with hydrocephalus decode words better than they understand what they read. We tested whether children with hydrocephalus (from myelomeningocele or aqueduct stenosis) (1) decode words slowly, (2) use decoding processes similar to those of neurologically intact peers, and (3) comprehend poorly to the extent that they are slow decoders. We compared speed of word decoding in 33 children with hydrocephalus and 33 controls matched on a pairwise basis for age, grade, and word decoding accuracy. The children with hydrocephalus were as fast as controls in reading words, but, unlike controls, they did not demonstrate an effect of spelling-sound regularity. Further, decoding speed did not contribute to reading comprehension beyond word decoding accuracy. The reading comprehension deficits of good decoders with hydrocephalus are not related to early-stage processing deficits in word recognition speed. Likely origins of comprehension failure in this group are discussed.     

Computer‐assisted reading intervention with a phonics approach for children using cochlear implants or hearing aids

The present study examined computer‐assisted reading intervention with a phonics approach for deaf and hard of hearing (DHH) children in Sweden using cochlear implants or hearing aids, or a combination of both. The study included 48 children, 5, 6 and 7 years of age. Sixteen children with normal hearing (NH) served as a reference group. The first purpose of the study was to compare NH and DHH children's reading ability at pre and post‐intervention. The second purpose was to investigate effects of the intervention. Cognitive and demographic factors were analyzed in relation to reading improvement. Results showed no statistically significant difference for reading ability at the group level, although NH children showed overall higher reading scores at both test points. Age comparisons revealed a statistically significant higher reading ability in the NH 7‐year‐olds compared to the DHH 7‐year‐olds. The intervention proved successful for word decoding accuracy, passage comprehension and as a reduction of nonword decoding errors in both NH and DHH children. Reading improvement was associated with complex working memory and phonological processing skills in NH children. Correspondent associations were observed with visual working memory and letter knowledge in the DHH children. Age was the only demographic factor that was significantly correlated with reading improvement. The results suggest that DHH children's beginning reading may be influenced by visual strategies that might explain the reading delay in the older children.     

Relations between enabling skills and reading comprehension: a follow-up study of Latvian students from first to second grade

In order to examine the relationships among various phonological skills and reading comprehension, Latvian children were followed from grade 1 to grade 2 and were tested with a battery of phonological, word reading, and reading comprehension tasks. A principal component analysis of the phonological tasks revealed three salient factors: a phonemic awareness factor, a rapid naming factor, and a short-term memory factor. In order to analyze the relationship between various phonological skills and reading comprehension, a structural modeling analysis was performed. Phonemic awareness and rapid naming explained approximately the same amount of unique variance in reading comprehension, but phonemic awareness had most predictive power indirectly via word decoding. Only rapid naming had a significant direct impact on reading comprehension.     

识字量和词汇知识在儿童阅读发展中的相对重要性

本研究基于简单阅读观理论,以两个样本共计666名大班至四年级的汉语儿童为研究对象,探索了识字量和词汇知识在儿童阅读能力发展中的作用及相对重要性的变化。结果显示,在阅读学习早期,识字量对阅读理解的重要性高于词汇知识。随着年级的升高,识字量的重要性降低,而词汇知识的重要性增加。这一发现证实简单阅读观理论也适用于解释汉语阅读能力的发展,并对今后的语文教学具有重要的启示意义。
