First-grade students (N = 221) were individually tested on a battery of cognitive and achievement measures of verbal fluency, visual attention, phonological awareness, orthographic recognition, rapid automatized naming (RAN) of letters and objects, and reading. All tests were subjected to postacquisition scoring, and all RAN measures were segregated into measures of articulation time, pause time, and consistency of the pause time. Structural equation modeling demonstrated that word reading was directly and significantly predicted by RAN letter naming and general RAN cognitive processing time of objects. Moreover, RAN letter reading constructs were significantly and directly predicted by the latent variables of phonological awareness, orthographic recognition, and general RAN object articulation and cognitive processing times. RAN letter naming constructs were also significantly and indirectly predicted by visual attention. The reading model was found to be consistent with a total mediation of the relation of phonological awareness and reading through RAN letter naming and supported the validity of the RAN letter naming subtest as a basic letter reading test. These findings supported the double-deficit hypothesis for letter reading. We suggest that phonological memory is a basic factor underlying general RAN cognitive processing time of objects and domain-specific information associated with phonemes and their graphic representations. 相似文献

This study examines (a) how rapid automatized naming (RAN) speed components—articulation time and pause time—predict reading accuracy and reading fluency in Grades 2 and 3, and (b) how RAN components are related to measures of phonological awareness, orthographic knowledge, and speed of processing. Forty-eight children were administered RAN tasks in Grades 1, 2, and 3. Results indicated that pause time was highly correlated with both reading accuracy and reading fluency measures and shared more of its predictive variance with orthographic knowledge than with phonological awareness or speed of processing. In contrast, articulation time was only weakly correlated with the reading measures and was rather independent from any processing skill at any point of measurement. 相似文献

In this 2-year longitudinal study the developmental relationships among letter knowledge, phonological awareness, rapid naming, and task orientation were examined, and linguistic-motivational pathways of word reading acquisition were traced from kindergarten to Grade 1 by means of structural equation modeling. The participants were 100 Finnish-speaking nonreaders. Results showed that kindergarten (5–6 years) letter knowledge predicted subsequent preschool (6–7 years) phonological awareness and task orientation. RAN was a unique longitudinal and concurrent predictor of word recognition, suggesting that rapid naming provides a reliable prediction of prospective word reading ability at least in a transparent language. Controlling for phonological awareness and rapid naming, task orientation contributed uniquely to the prediction of word reading competence, suggesting that motivational and linguistic factors are both at work as children face the gradually growing demands of learning to read and write in Grade 1. 相似文献

This study examines the core predictors of the covariance in reading and arithmetic fluency and the domain-general cognitive skills that explain the core predictors and covariance. Seven-year-old Finnish children (N = 200) were assessed on rapid automatized naming (RAN), phonological awareness, letter knowledge, verbal counting, number writing, number comparison, memory skills, and processing and articulation speed in the spring of Grade 1 and on reading and arithmetic fluency in the fall of Grade 2. RAN and verbal counting were strongly associated, and a constructed latent factor, serial retrieval fluency (SRF), was the strongest unique predictor of the shared variance. Other unique predictors were phonological awareness, number comparison, and processing speed. Findings highlight the importance of SRF in clarifying the relation between reading and arithmetic fluency. 相似文献

This study aimed to identify predictors of single word spelling performance in children using a novel test containing regular words, irregular words and pseudowords. We assessed reading ability, letter-sound knowledge, phonological awareness (PA) and rapid automatised naming (RAN) in children aged 4–12 years (N = 641). Mixed model analyses with hierarchical nested data were conducted with Year_group (Yr R to Yr 6) included as a factor, PA and RAN as predictors, and reading and letter-sound knowledge as covariates. For irregular word spelling, PA and RAN were significant predictors, but the associations were dependent upon the year the children attended. Interestingly, for regular words and pseudowords PA was not significantly related. For pseudowords, only RAN was a significant predictor and only in Yr 2. We argue that a better understanding of spelling development can be achieved using tools that distinguish between regular and irregular words and pseudowords, as different processes seem to be associated with the different types of letter string across the variable levels of spelling experience. 相似文献

Although phonemic awareness is a well-known factor predicting early reading development, there is also evidence that Rapid Automatized Naming (RAN) is an independent factor that contributes to early reading. The aim of this study is to examine phonemic awareness and RAN as predictors of reading speed, reading comprehension and spelling for children with reading difficulties. It also investigates a possible reciprocal relationship between RAN and reading skills, and the possibility of enhancing RAN by intervention. These issues are addressed by examining longitudinal data from a randomised reading intervention study carried out in Sweden for 9-year-old children with reading difficulties (N?=?112). The intervention comprised three main elements: training of phonics, reading comprehension strategies and reading speed. The analysis of the data was carried out using structural equation modelling. The results demonstrated that after controlling for autoregressive effects and non-verbal IQ, RAN predicts reading speed whereas phonemic awareness predicts reading comprehension and spelling. RAN was significantly enhanced by training and a reciprocal relationship between reading speed and RAN was found. These findings contribute to support the view that both phonemic awareness and RAN independently influence early phases of reading, and that both are possible to enhance by training. 相似文献

This study examined the extent to which reading and arithmetic skills show covariation at Grade 1 and at Grade 7, to what extent this covariation is time-invariant or time-specific, and to what extent different antecedents will predict these time-invariant and time-specific portions of the covariation. The reading and arithmetic skills of a total of 1335 Finnish children were assessed at the end of Grade 1 and then again at the end of Grade 7. Phonological awareness, letter knowledge, rapid automatized naming (RAN), counting, and parental education levels were measured in kindergarten; working memory at Grade 1 and nonverbal reasoning at Grade 3. The results showed that reading and arithmetic had a substantial amount of covariation at grades 1 and 7, and that most of the covariation between these grades was time-invariant and could be predicted by RAN, counting, letter knowledge, working memory, and nonverbal reasoning. The time-specific portion of the covariation between reading and arithmetic in Grade 1 was predicted by phonological awareness, letter knowledge, and counting; while time-specific covariation in Grade 7 was predicted by parental education level and nonverbal reasoning. 相似文献

Although research has established that performance on a rapid automatized naming (RAN) task is related to reading, the nature
of this relationship is unclear. Bowers (2001) proposed that processes underlying performance on the RAN task and orthographic knowledge make independent and additive
contributions to reading performance. We examined the benefits of training orthographic pattern recognition and speeded letter
recognition for children in Grades 1 and 2 with slow naming speed. Children first received training in either orthographic
pattern recognition or speeded letter recognition, and then switched to the other type of training. Results indicated that
speeded letter recognition can improve through training, but only when preceded by training in orthographic pattern recognition.
Orthographic pattern recognition training improved the accuracy and speed of reading training words, whether training occurred
alone or following letter training. Letter training prior to the orthographic training provided no additional benefit. Together,
these results argue for the importance of orthographic training for children with slow naming speed. 相似文献

The present study examined phoneme awareness, phonological short term memory, letter knowledge, rapid automatized naming (RAN), and visual–verbal paired associate learning (PAL) as longitudinal predictors of spelling skills in an early phase (Grade 2) and a later phase (Grade 5) of development in a sample of 140 children learning to spell in the opaque Danish orthography. Important features of the study were the inclusion of PAL measures and the fact that the children were followed up to Grade 5. Findings from other orthographies were replicated, in that phonological processing (awareness and memory) and RAN accounted for unique variance in early spelling skills. For later spelling skills, Grade 2 spelling was by far the most powerful predictor. PAL-nonwords was the only measure to explain additional unique variance. It is suggested that PAL-nonwords taps the ability to establish representations of new phonological forms and that this ability is important for the acquisition of orthographic spelling knowledge. 相似文献

We examined whether akshara knowledge, phonological awareness, phonological memory, and RAN predict variability in word and nonword reading skills in Grade 1–4 children (N?=?200) learning to read Sinhala. Hierarchical regression analyses showed that akshara knowledge had the strongest unique association with both word and nonword reading accuracy across grades. Akshara knowledge and RAN predicted word and nonword reading fluency. The impact of phonological memory and syllable awareness on reading was mostly mediated by akshara knowledge, and phoneme awareness was not uniquely associated with word reading skills in any grade. These results suggest that there are multiple cognitive correlates of accurate and fluent word reading in Sinhala, and akshara knowledge is the most important predictor of learning to read words. The findings have implications for the literacy acquisition, development, and instruction in alphasyllabaries.

The degree to which orthographic knowledge accounts for the link between rapid automatized naming (RAN) and reading is contested, with mixed results reported. This longitudinal study compared two groups of 10- and 11-year-old children, a low RAN group (N = 69) and matched controls (N = 74), on various measures of orthographic knowledge. The low RAN group showed a deficit in orthographic knowledge, both at the level of subword letter sequences and of whole words, as well as an unexpected strength in orthographic learning. Our findings underline the persistence of RAN-related reading problems and raise questions about reading strategies in this group. 相似文献

We examined the growth of spelling skills in a large sample of Norwegian children (N = 228) over the first 3 years in school. The roles of phoneme awareness, letter knowledge, rapid automatized naming (RAN), visual–verbal paired-associate learning, and verbal short-term memory as predictors of later spelling skills were examined. Phoneme awareness and letter knowledge together with nonalphanumeric RAN and verbal short-term memory were independent longitudinal predictors of both word and nonword spelling. In addition growth mixture modeling suggested that individual variations in the growth of word spelling were best characterized as variations around a single trajectory, whereas growth in nonword spelling was better characterized as variations around two distinct trajectories. The results are related to current theories about the cognitive and linguistic foundations of spelling. 相似文献

Concurrent relationships among measures of naming speed, phonological awareness, orthographic skill, and other reading subskills were explored in a representative sample of second graders. Hierarchical regression analyses revealed that naming speed, as measured by the the rapid automatized naming (RAN) task, accounted for a sizable amount of unique variance in reading with vocabulary and phonemic awareness partialled out. The unique contribution of naming speed to reading was relatively stronger for orthographic skills, whereas the contribution of phonemic skills was stronger for nonword decoding. In further analyses, marked difficulties on a range of reading tasks, including orthographic processing, were seen in a subgroup with a double deficit (slow naming speed and low phonemic awareness) but not in groups with only a single deficit. These findings are broadly consistent with Bowers and Wolf's (1993a, 1993b; Wolf & Bowers, 1999) double-deficit hypothesis of reading disability. 相似文献

Research into sighted children’s reading shows that letter recognition skill predicts phonological awareness skill. Congenitally–blind children do not receive exposure to environmental print and do not generally learn to recognise written letters of the alphabet prior to schooling in Braille. A cross–sectional analysis revealed that blind children with no knowledge of written letters or written words showed no ability at measures of phonological awareness. Blind children with knowledge of written letters and no written words showed much increased phonological awareness scores and blind children with knowledge of written letters and written words scored higher still on phonological awareness measures. It was concluded that letter learning is a major contributor to the development of phonological awareness in blind children. It suggests key similarities in the underlying processes of reading development across two different populations using different modalities to learn to read. 相似文献

We examined the developmental relations of phonological awareness (PA) and rapid automatized naming (RAN) with reading in a cross-sectional study with 874 Spanish children from Grades 2 to 6. Our main prediction was that the RAN–reading relationship would decrease due to a gradual change in reading strategy, from serial decoding to sight word reading. Therefore, in contrast to most previous studies, we used discrete reading tasks. Serial RAN tasks for objects, colors, digits, and letters were included. First, we examined whether the RAN tasks loaded on the same constructs across time. An alphanumeric and a nonalphanumeric factor were identified, which were invariant over time. In subsequent multigroup structural equation models we found that the PA–reading relationship was low but slightly increased in the higher grades. As predicted, the RAN–reading relationship decreased for words, whereas the relationship remained stable for pseudowords. 相似文献

Prosodic awareness has been linked with reading accuracy in typically developing children. Although children with autism spectrum disorders (ASD) often have difficulty processing prosody and often have trouble learning to read, no previous study has looked at the link between explicit prosodic awareness and reading in ASD. In the current study, 29 early readers with ASD (5–11 years) completed word and nonword reading accuracy tasks and two measures of prosodic awareness. Tasks relating to phonological awareness, oral language, vocabulary, letter knowledge and nonverbal intelligence were also administered. A key finding was that there was a relationship between prosodic awareness and both word and nonword reading accuracy. 相似文献

Previous meta-analyses on the relationship between phonological awareness, rapid automatized naming (RAN), and reading have been conducted primarily in English, an atypical alphabetic orthography. Here, we aimed to examine the association between phonological awareness, RAN, and word reading in a nonalphabetic language (Chinese). A random-effects model analysis of data from 35 studies revealed a moderate relationship of phonological awareness with reading accuracy (r = .36) and reading fluency (r = .39). RAN also correlated significantly with reading accuracy (r = –.38) and reading fluency (r = –.51), but its relationship varied as a function of test type (graphological RAN correlated more strongly with reading than nongraphological RAN) and reading outcome (RAN correlated more strongly with reading fluency than reading accuracy). Age/grade and dialect (Mandarin vs. Cantonese) did not influence the size of the correlations. Taken together, the findings of this meta-analysis suggest that phonological awareness and RAN are universal correlates of word reading. 相似文献

Some cognitive processes may be shared between reading comprehension and reading fluency, while others may be independent. In this longitudinal study, 127 Chinese children in grades 1–2 were tested three times (T1–T3) to explore the contributions of early morphological awareness and rapid automatized naming (RAN) to subsequent reading comprehension and reading fluency. The results demonstrated that both T1 morphological awareness and RAN directly and significantly explained a similar amount of variance in T3 reading comprehension and reading fluency. T1 Morphological awareness predicted T3 reading comprehension via T2 word-reading accuracy but not word-reading fluency, whereas the indirect influence of T1 RAN on T3 reading comprehension was not significant. In contrast, morphological awareness predicted reading fluency via word-reading accuracy and fluency, while RAN predicted it only via word-reading fluency not accuracy. The findings add to the growing literature by providing evidence of the similarities and differences in the cognitive underpinnings of reading comprehension versus reading fluency in Chinese children.

The present study investigates whether grade 6 reading outcomes, reading fluency, and reading comprehension can be predicted by grade 3 reading fluency, familial risk of dyslexia (FR), and grade 3 reading related skills: rapid automatized naming (RAN), phonological awareness (PA), and vocabulary. In a sample of 150 children, of whom 83 had a parent with dyslexia, correlation and regression analyses were performed. FR, measured on a continuous scale, was by itself related to all outcomes. However, FR did not explain any variance on top of grade 3 reading fluency. Grade 3 reading fluency strongly predicted grade 6 reading fluency and was also related to reading comprehension. RAN improved the prediction of grade 6 reading fluency, though the additional explained variance was small. Vocabulary and PA fully explained the variance that grade 3 reading fluency explained in grade 6 reading comprehension. Vocabulary explained a substantial amount of variance in grade 6 reading comprehension making it an interesting clinical target. As we used continuous measures of reading fluency and FR, our findings are not biased by distinct diagnostic criteria. 相似文献

A sample of 169 German children were tested in general verbal ability, verbal memory span, phonological awareness, lexical access speed and accuracy, and letter knowledge in preschool. These tests were used as independent measures predicting performance on second grade reading comprehension, word discrimination, and word decoding speed. Tests of verbal ability, memory capacity, and phonological awareness were also given over a year later in elementary school. After determining that the influence of verbal ability, memory capacity, and phonological awareness on reading comprehension was comparable when measured in preschool and elementary school, the effects of all preschool measures on the three dependent reading measures were assessed. These analyses revealed differential main effects and interactions for the three dependent measures. However, a significant three-way interaction among lexical access, memory capacity, and phonological awareness was found for all three reading measures. These results indicate that the interaction and subsequent effects of these linguistic skills precedes and influences reading acquisition. This is contrary to the view that these skills interact as a result of reading experience. The implications of these results, as well as comparisons of conducting such studies with German rather than English speaking children are discussed. 相似文献
