语素意识、语音意识和快速命名在学前儿童言语能力发展中的预测作用:来自追踪研究的证据*

为探讨语素意识、语音意识和快速命名三种认知技能对汉语儿童口语词汇、汉字识别和阅读理解等言语能力发展的预测作用,本研究对74名学前儿童进行了一年半的追踪测查,结果发现:(1) 学前儿童的各项认知技能和言语能力随时间均有显著提高;(2)在控制了因变量的自回归效应和其他两种认知技能后,语音意识对一年半后的口语词汇成绩仍有独特的解释作用,快速命名能预测一年半后的汉字识别成绩,而语素意识是解释一年半后儿童汉字识别和阅读理解能力发展的重要变量。     

PASS认知过程:能够解释RAN-阅读之间的关系吗?(英文)

本研究考察了计划、注意、同时性加工和继时性加工这些PASS认知技能,在多大程度上能够预测快速命名和单词阅读之间的共同变异量。84位说英语读三年级和四年级的加拿大儿童,接受了客体和颜色快速命名、单词确认、计划、注意、同时性加工和继时性加工任务的测量。结果表明,计划和继时性加工能够对快速命名和阅读之间的共同变异量做出显著的解释。这一结果表明,在探寻快速阅读与阅读密切关联的原因时,应充分考虑这两个认知过程。     

语音意识、语素意识和快速命名在儿童言语发展中的作用

以130名幼儿园小、中、大班儿童为研究对象,通过分层回归,系统比较了语音意识、语素意识和快速命名三种认知技能在学前儿童口语词汇、汉字识别和阅读理解等言语能力发展中的作用和相对重要性,结果发现:(1)学前儿童的各项能力随着年龄的增加而显著提高;(2)除了年龄因素之外,语音意识和语素意识是解释口语词汇的重要变量;(3)在控制了年龄和口语词汇量之后,语音意识、语素意识和快速命名能力都分别对汉字识别成绩具有独立的预测作用;(4)在控制了年龄、口语词汇量、汉字识别和其他两种认知技能之后,只有语素意识仍然能够独立预测阅读理解成绩,表明语素意识对于汉语阅读能力的发展具有独特的作用.     

Visual rapid naming and phonological abilities: different subtypes in dyslexic children

One implication of the double-deficit hypothesis for dyslexia is that there should be subtypes of dyslexic readers that exhibit rapid naming deficits with or without concomitant phonological processing problems. In the current study, we investigated the validity of this hypothesis for Portuguese orthography, which is more consistent than English orthography, by exploring different cognitive profiles in a sample of dyslexic children. In particular, we were interested in identifying readers characterized by a pure rapid automatized naming deficit. We also examined whether rapid naming and phonological awareness independently account for individual differences in reading performance. We characterized the performance of dyslexic readers and a control group of normal readers matched for age on reading, visual rapid naming and phonological processing tasks. Our results suggest that there is a subgroup of dyslexic readers with intact phonological processing capacity (in terms of both accuracy and speed measures) but poor rapid naming skills. We also provide evidence for an independent association between rapid naming and reading competence in the dyslexic sample, when the effect of phonological skills was controlled. Altogether, the results are more consistent with the view that rapid naming problems in dyslexia represent a second core deficit rather than an exclusive phonological explanation for the rapid naming deficits. Furthermore, additional non-phonological processes, which subserve rapid naming performance, contribute independently to reading development.     

汉语发展性阅读障碍亚类型的初步探讨

以阅读水平匹配组为参照对29名汉语发展性阅读障碍儿童的认知缺陷模式进行了分析,并考察了不同亚类型阅读障碍儿童的汉字识别模式。结果表明汉语发展性阅读障碍存在不同的亚类型,以语音缺陷型、快速命名缺陷型及两者结合的双重缺陷型为主,与英语国家研究中的双重缺陷假设一致。语音缺陷型儿童汉字识别时有更多的语义错误,对声旁中的部分语音线索不敏感;快速命名缺陷型儿童汉字识别时依赖声旁语音线索,表现出阅读发展的一般延迟;双重或多重认知缺陷型是阅读损伤最严重的亚类型     

阅读困难可否补救? 两种理论驱动干预方案的比较(英文)

本研究是一个进行中的纵向实验的一部分,该实验旨在比较一个认知干预方案(PREP:PASS阅读促进方案)和一个主要关注语音、命名速度和意义成分的神经心理方案(DEST-RT:DEST补救工具)在阅读困难补救中的效能。从320位儿童构成的初始样本中,选择4组儿童,并一年级接受四周干预后,对他们在许多认知、语言、阅读和正字法测量上的表现进行比较:两个实验组共28名伴有阅读困难的儿童(每组n=14),平均年龄6岁6个月,分配到PREP和DEST-RT补救方案中,两组儿童基于年龄、性别、父母教育水平、非言语和言语能力进行匹配,同时也考虑他们的认知和语言表现剖面;一个阅读水平匹配组(RA-C,n=19),也存在阅读困难,不接受任何处理;一个实足年龄匹配组(CA-C,n=30)。结果表明,所有四组儿童在所有认知、语言、阅读和正字法测量上均随时间而改善;与CA-C和DEST-RT相比,PREP组在继时性加工上进步显著;在正字法选择,这一在单词加工中利用视觉-字形信息的正字法加工任务上,PREP组的表现也优于DEST-RT组;最后,在语音敏感性、字母数字的RAN、单词阅读(真词和假词)及段落理解等方面,PREP和DEST-RT的表现均显著优于CA-C和RA-C。讨论部分,则着重讨论设计理论驱动的低成本且能有效改善阅读表现的补救方案的必要性。     

语音意识、命名速度和语素意识在汉语阅读发展中的作用

以123名小学四、五年级汉语儿童为研究对象,采用回归分析、结构方程模型探讨语音意识、命名速度和语素意识在阅读能力不同方面（准确性、流畅性和理解）的作用。结果显示,语音意识、命名速度和语素意识都是影响阅读能力的重要认知因素,但对不同方面阅读能力的作用存在差异：（1）语音意识、命名速度和语素意识均直接影响阅读准确性,且语素意识的贡献相对较大;（2）命名速度除直接影响阅读流畅性外,还通过阅读准确性的部分中介作用影响阅读流畅性,而语音意识和语素意识则通过阅读准确性的完全中介作用影响阅读流畅性;（3）语音意识、命名速度和语素意识对阅读理解均无直接影响,分别通过阅读准确性和阅读流畅性间接影响阅读理解。     

Learning to read in Chinese: Evidence for reciprocal relationships between word reading and oral language skills

This study investigates the longitudinal predictors of the development of Chinese word reading skills and potential bidirectional relationships between Chinese word reading and oral language skills. We examine, in a 2‐year longitudinal study, a wide range of theoretically important predictors (phonological awareness, tone awareness, morphological awareness, visual skills, rapid automatized naming, Pinyin knowledge, and vocabulary knowledge) of reading in 143 primary‐school children living in mainland China. Initial levels of reading were predicted by vocabulary knowledge, phonological awareness, and visual discrimination skills. Only initial reading levels predicted growth in reading. Initial reading also predicted growth in vocabulary knowledge and morphological construction. This pattern demonstrates that the early stages of learning to read in Chinese places demands on semantic (vocabulary) and visual skills in addition to phonological skills. Furthermore, early levels of word reading predict the growth of vocabulary knowledge and morphological awareness suggesting that the development of these oral language skills is facilitated by learning to read.     

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.     

汉语阅读障碍的语音加工及正字法加工缺陷的实验研究

本研究对汉语阅读障碍的加工缺陷进行探讨,期望有助于揭示语言加工的普遍性与特殊性,以及阅读障碍的成因,并可为后期的干预提供帮助。研究采用改编的言语认知测验对阅读水平匹配组与阅读障碍组和生理年龄匹配组进行比较后发现,阅读障碍组在语音意识和正字法加工任务上的成绩均明显差于生理年龄控制组和阅读水平匹配组;阅读障碍组在快速命名和语音记忆任务上的成绩不如生理年龄匹配组,仅达到阅读水平匹配组水平。因此,汉语发展性阅读障碍儿童存在语音意识和正字法加工缺陷,这两种缺陷可能是阅读障碍儿童面临的最主要的两大缺陷;阅读障碍儿童在快速命名和语音记忆上的不足可能是发展迟滞所致。同时,大多数的汉语阅读障碍儿童存在不止一种的认知缺陷。阅读障碍儿童在语音意识和正字法加工上存在缺陷的比例最高。     

Evidence of a highly specific relationship between rapid automatic naming of digits and text-reading speed

This paper explores the specificity of the relationship between rapid automatic naming and reading fluency. Reading accuracy, rate, and fluency was measured among a sample of 67 children, the majority of whom were very poor readers. Regression analyses revealed that phonological processing tasks predicted reading accuracy and comprehension whereas rapid digit (but not picture) naming predicted reading accuracy and rate. After further controlling reading accuracy, digit naming was still a significant predictor of reading rate. This suggests that rapid alphanumeric naming is a highly specific predictor of reading rate and that rapid digit naming and phonological processing are distinct contributors to different aspects of reading in poor readers.     

Anchoring in 4- to 6-year-old children relates to predictors of reading

Previous studies suggest that anchoring, a short-term dynamic and implicit process that allows individuals to benefit from contextual information embedded in stimulus sequences, might be causally related to reading acquisition. Here we report findings from two experiments in which two previously untested predictions derived from this anchoring hypothesis were tested: (a) that anchoring facilitates rapid naming and phonological short-term memory in children prior to the onset of formal reading instruction and (b) that anchoring makes a unique contribution to performance in two early predictors of reading (letter knowledge and phonological awareness). In line with those predictions, naming times were faster and memory spans were longer under conditions that encouraged the use of anchoring processes than under conditions that afforded little anchoring. Furthermore, performance in the anchoring-affording condition predicted significant amounts of variance in phonological awareness and letter knowledge even after controlling for the contribution of the conditions that did not afford anchoring. Therefore, we suggest that anchoring might contribute to the development of reading-related processes during the preschool years independent of the development of specific reading-related skills such as phonological processing.     

The cognitive bases of learning to read and spell in Greek: evidence from a longitudinal study

We conducted a longitudinal study examining the role of phonemic awareness, phonological processing, and grammatical skills in the development of reading and spelling abilities in Greek. A battery of cognitive, linguistic, and literacy tasks was administered to 131 primary school children (65 7-year-olds and 66 9-year-olds) and was repeated in the following year (8- and 10-year-olds, respectively). Phoneme awareness, speech rate, and rapid automatized naming (RAN) were concurrent predictors of reading rate at Time 1 (T1), and speech rate was a longitudinal predictor of reading rate at Time 2 (T2) when reading at T1 was controlled. The predictors of spelling differed from those of reading; phoneme awareness and speech rate predicted concurrent attainments at T1, and phoneme awareness was a robust longitudinal predictor. Despite the differences in the degree of transparency between the Greek and English orthographies, phoneme awareness predicts variations in learning to read and spell in both languages.     

The relationship between phonological processing and arithmetic in children with learning disabilities

Phonological processing skills have not only been shown to be important for reading skills, but also for arithmetic skills. Specifically, previous research in typically developing children has suggested that phonological processing skills may be more closely related to arithmetic problems that are solved through fact retrieval (e.g., remembering the solution from memory) than procedural computation (e.g., counting). However, the relationship between phonological processing and arithmetic in children with learning disabilities (LDs) has not been investigated. Yet, understanding these relationships in children with LDs is especially important because it can help elucidate the cognitive underpinnings of math difficulties, explain why reading and math disabilities frequently co-occur, and provide information on which cognitive skills to target for interventions. In 63 children with LDs, we examined the relationship between different phonological processing skills (phonemic awareness, phonological memory, and rapid serial naming) and arithmetic. We distinguished between arithmetic problems that tend to be solved with fact retrieval versus procedural computation to determine whether phonological processing skills are differentially related to these two arithmetic processes. We found that phonemic awareness, but not phonological memory or rapid serial naming, was related to arithmetic fact retrieval. We also found no association between any phonological processing skills and procedural computation. These results converge with prior research in typically developing children and suggest that phonemic awareness is also related to arithmetic fact retrieval in children with LD. These results raise the possibility that phonemic awareness training might improve both reading and arithmetic fact retrieval skills.

Research Highlights

• Relationships between phonological processing and various arithmetic skills were investigated in children with learning disabilities (LDs) for the first time.
• We found phonemic awareness was related to arithmetic involving fact retrieval, but not to arithmetic involving procedural computation in LDs.
• The results suggest that phonemic awareness is not only important to skilled reading, but also to some aspects of arithmetic.
• These results raise the question of whether intervention in phonemic awareness might improve arithmetic fact retrieval skills.

     

Rapid naming speed components and reading development in a consistent orthography

We examined how rapid automatized naming (RAN) components-articulation time and pause time-predict word and text reading fluency in a consistent orthography (Greek). In total, 68 children were followed from Grade 2 to Grade 6 and were assessed three times on RAN (Digits and Objects), phonological awareness, orthographic processing, speed of processing, and reading fluency. Both RAN components were strongly related to reading fluency and, with few exceptions, accounted for unique variance over and above the contribution of speed of processing, phonological awareness, and orthographic processing. The amount of predictive variance shared between the components and the cognitive processing skills varied across time. The implications of these findings for the RAN-reading relationship are discussed.     

Neuropsychological profile of adult dyslexics

One hundred and fifteen adults with well-documented childhood reading status underwent a series of neuropsychological tests including tests of memory, attention, phonological processing, and visual perceptual skills in an attempt to define the neuropsychological profile of dyslexia in adulthood. Compared to a normal nonreading disabled sample, subjects with a history of reading disability performed consistently poorer on most neuropsychological tests. However, after covarying for intelligence and socioeconomic status, only tests of rapid naming, phonological awareness, and nonword reading were significant discriminating measures. The hypothesis that deficits in phonological processing comprise the core cognitive deficits in adults with a history of reading disability was supported. Independent of current adult reading ability, measures of nonword reading, phonological awareness, and rapid naming serve as indicators of a childhood history of reading disability.     

The relationship between phonological skills and word decoding

Word decoding ability is a critical factor in reading performance. In the present study, we examined the relationship between word decoding ability and three different phonological skills; phonemic awareness, verbal short-term memory (V-STM), and rapid automatic naming (RAN) in 1007 Scandinavian third- and fifth-graders. In the first part of the study, we sought to investigate the influence of the three phonological skills on word decoding ability. Using multiple regression analysis, our result clearly demonstrated that phonemic awareness was the most powerful phonological skill explaining variance in word decoding ability among average decoders. Among children with poor decoding skills, however, RAN was the most important factor in Grade 3, whereas V-STM was the main contributor to decoding ability among children in Grade 5. In the second part of the research, we examined the relationship between poor phonological skills and word decoding ability. Interestingly, our result revealed that approximately one half of the children with phonological difficulties, still performed within the average range with regard to word decoding ability. However, our analyses confirmed earlier research concerning the severe word decoding difficulties children with both poor phonemic awareness and restricted V-STM, experience.

元语言意识和快速命名对小学生汉字听写的影响

汉字听写是小学生读写能力的重要组成部分,受多种认知技能影响。以858名小学一至六年级学生为对象,考察了元语言意识（语音意识、语素意识、正字法意识）和快速命名对汉字听写的影响,在控制了智力和口语词汇的影响后,结果发现：（1）语音意识和正字法意识在低年级儿童的汉字听写中起着重要作用,对中、高年级没有显著影响;（2）快速命名在中、高年级儿童的汉字听写中起着独特作用,而对低年级没有显著影响;（3）语素意识对整个小学阶段的汉字听写都起着重要作用。研究结果表明,各认知技能在儿童不同的发展阶段对汉字听写的作用有所不同。     

The Development of Sensitivity to Sublexical Orthographic Constraints: An Investigation of Positional Frequency and Consistency Using a Wordlikeness Choice Task

The developmental sequence of the types of orthographic knowledge that children acquire early in reading development is unclear. Following findings of skilled reading, the orthographic constraints of positional frequency and feedback consistency were explored with a wordlikeness judgement task for grades 1–3 English-speaking children. The data provide evidence for the early development of sensitivity to positional frequency, but not sound-spelling consistency. However, sensitivity to each type of orthographic structure was predicted by rapid naming and sensitivity to consistency was predicted by phonological awareness. As well, sensitivity to each type of constraint was related to word reading fluency.
