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

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

Phonological awareness (PA) and rapid automatised naming (RAN) skills in relation to reading acquisition were examined using two languages, one with a deep orthography (English) and the other with a shallow orthography (Korean). Participants were 50 Korean American children who spoke English as a dominant language (DL) and were learning to read Korean as a sequential language (SL). Parallel measures in English and Korean assessed PA, RAN and reading skills. The results showed the similarities and differences between the DL and SL acquisition patterns for PA and RAN. While PA skills of the DL were a dominant predictor in SL reading achievement, RAN became important for the children with the higher level of SL reading performance. This cross‐sectional study indicates that proficiencies of PA and RAN in the DL are the pathway to reading success in an SL. This suggests that a universal thread exists in learning dual languages, despite dissimilar orthography, phonology and writing systems. 相似文献

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

A cohort of 92 children was followed through sixth grade to investigate the relationship of preschool skills and first grade
phonological awareness to reading and spelling. In particular, the focus was on the changing roles of letter naming, orthographic
awareness, and phonological processing in prediction, as reading experience increased. Preschool letter naming was a consistently
significant predictor of reading vocabulary, reading comprehension, and spelling at each grade level, but the preschool orthographic
task contributed most to reading comprehension and spelling at the higher grades. Conversely, the contribution of the first
grade phonemic awareness measures to reading skills dropped sharply after third grade, although they continued to contribute
to spelling prediction. When preschool precursors of phonological processing were examined, letter naming was found to be
a predictor of first and third grade phonemic awareness. Findings confirm the importance of letter naming as a predictor and
of the role of phonemic awareness in early reading acquisition, but also highlight the contribution of orthographic processing
skills to later reading. 相似文献

Reading fluency beyond decoding is a limitation to many children with developmental reading disorders. In the interest of
remediating dysfluency, contributing factors need to be explored and understood in a developmental framework. The focus of
this study is orthographic processing in developmental dyslexia, and how it may contribute to reading fluency. We investigated
orthographic processing speed and accuracy by children identified with dyslexia that were enrolled in an intensive, fluency-based
intervention using a timed visual search task as a tool to measure orthographic recognition. Results indicate both age and
treatment effects, and delineate a link between rapid letter naming and efficient orthographic recognition. Orthographic efficiency
was related to reading speed for passages, but not spelling performance. The role of orthographic learning in reading fluency
and remediation is discussed. 相似文献

We examined (a) how rapid automatized naming (RAN) components—articulation time and pause time—predict reading accuracy and reading fluency in Grades 4 and 5, and (b) what cognitive-processing skills (phonological processing, orthographic processing, or speed of processing) mediate the RAN–reading relationship. Sixty children were followed from Grade 3 to Grade 5 and were administered RAN (Letters and Digits), phonological processing, lexical and sublexical orthographic processing, speed of processing, reading accuracy, and fluency tasks. Pause time was highly correlated with reading fluency and shared more of its predictive variance with lexical orthographic processing and speed of processing than with phonological processing. Articulation time also predicted reading fluency, and its contribution was mostly independent from other cognitive-processing skills. Implications for the relationship between RAN and reading are discussed. 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

This study investigated whether two different versions of the serial rapid automatized naming (RAN) task, using similar alphanumeric stimuli, would differentially predict performance on word level reading skills (i.e., word recognition, nonword reading, and orthographic processing). To accomplish this, a subset of the Colorado Learning Disabilities Research Center twin sample (N = 307) was administered two different versions of serial RAN (traditional and alternative), and the relationship among these measures and word level reading skills was examined using an extension of multiple regression analysis known as dominance analysis (Budescu, 1993). The traditional RAN task (RAN-T) involved rapidly naming a visual array of 50 items, consisting of 5 symbols in a given category that are presented 10 times in random order in 5 rows (Denckla & Rudel, 1976). In the alternative RAN task (RAN-A), participants were presented with a similar set of 6 symbols in 5-item rows but asked to name as many items as possible in 15 sec. Results of dominance analysis indicate that the RAN-A measure explained significantly more unique variance in word recognition and orthographic-processing skills than the RAN-T task. In the case of word recognition skill, RAN-A was found to dominate RAN-T. Several explanations for this pattern of results across the two versions of RAN are explored. 相似文献

Arabic native speaking children are born into a unique linguistic context called diglossia (Ferguson, word, 14, 47–56, [1959]). In this context, children grow up speaking a Spoken Arabic Vernacular (SAV), which is an exclusively
spoken language, but later learn to read another linguistically related form, Modern Standard Arabic (MSA). Forty-two first-grade
Arabic native speaking children were given five measures of basic reading processes: two cognitive (rapid automatized naming
and short-term working memory), two phonological (phoneme discrimination and phoneme isolation), and one orthographic (letter
recoding speed). In addition, the study produced independent measures of phonological processing for MSA phonemes (phonemes
that are not within the spoken vernacular of children) and SAV phonemes (phonemes that are familiar to children from their
oral vernacular). The relevance of these skills to MSA pseudoword reading fluency (words correct per minute) in vowelized
Arabic was tested. The results showed that all predictor measures, except phoneme discrimination, correlated with pseudoword
reading fluency. Although phonological processing (phoneme isolation and discrimination) for MSA phonemes was more challenging
than that for SAV phonemes, phonological skills were not found to affect reading fluency directly. Stepwise regression analysis
showed that the strongest predictor of reading fluency in vowelized Arabic was letter recoding speed. Letter recoding speed
was predicted by memory, rapid naming, and phoneme isolation. The results are discussed in light of Arabic diglossia and the
shallow orthography of vowelized Arabic. 相似文献

We investigate whether orthographic processes influence the identification and encoding of letter position within letter strings. To minimise word‐specific effects, we adopt a visual letter search task that requires participants to identify a cued letter target among a random five‐letter string. Using this paradigm, previous studies have shown that letter targets to the left are identified faster than those to the right of centre and letter targets in the initial, medial and final positions are identified faster than those in neighbouring positions. While the medial letter advantage is likely to arise from greater visual acuity at the point of fixation, the mechanisms responsible for the left‐to‐right, and exterior, letter advantage have yet to be determined. We show that: (i) search functions for most letters reflect the directional scanning process required for reading English orthography; (ii) search times are significantly faster for letter targets that appear in the most, compared with the least, frequent position in written words; and (iii) search times correlate significantly with positional letter frequency, especially in the initial and final positions. We propose that a combination of low‐level visual, and higher‐level orthographic, processes modulate the encoding of letter identities and position in written word recognition. 相似文献

Letter Processing and the Formation of Memory Representations in Children with Naming Speed Deficits
The ability to recognize letter patterns within words as a single unit is important for fluent reading. This skill is based
on previously established memory representations of common letter patterns. The ability to form these memory representations
may be impaired in some poor readers, particularly readers with naming speed deficits (NSD). This study explored factors that
influence letter processing and the subsequent formation of memory representations of letter strings in children with and
without a NSD. Children were presented with a letter string, followed by a probe unit that was either a single letter, a two-letter
cluster, or a repetition of the whole string. Children indicated whether or not the probe had been present in the preceding
string. Two factors were manipulated: (a) amount of time to process the initial letter string, and (b) level of orthographic
structure present in the letter string. Results indicated that overall, children with NSD performed less accurately than children
without NSD. However, children with NSD showed no differential benefit in performance as a result of longer time to process
a letter string. In addition, all readers were able to make use of the orthographic structure in a letter string to aid performance.
Implications of results for establishing memory representations of letter strings are discussed. 相似文献

Rapid naming speed and Chinese character recognition 总被引：1，自引：0，他引：1
We examined the relationship between rapid naming speed (RAN) and Chinese character recognition accuracy and fluency. Sixty-three
grade 2 and 54 grade 4 Taiwanese children were administered four RAN tasks (colors, digits, Zhu-Yin-Fu-Hao, characters), and
two character recognition tasks. RAN tasks accounted for more reading variance in grade 4 than in grade 2, and graphological
RAN tasks accounted for more reading variance than RAN Colors. After controlling for age, nonverbal intelligence, phonological
sensitivity, short-term memory, and orthographic processing, RAN tasks were significant predictors of character recognition
fluency in grade 2, and of both accuracy and fluency in grade 4. 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

We examined the nature of and factors related to adolescents’ reading difficulties in a highly transparent orthography. We compared word, pseudoword, and text reading speed and accuracy, rapid naming (RAN) and phonological processing between poor readers (n?=?80) and normally developing readers (n?=?189). Reading problems were manifested in reading speed and in timed pseudoword reading accuracy. RAN predicted speed, and phonological processing predicted accuracy of reading in both groups. Among poor readers, RAN also explained reading accuracy. For the normally developing sample, phonological processing also predicted reading speed. 相似文献

ABSTRACTAlthough phonological awareness (PA) and rapid automatized naming (RAN) are confirmed as early predictors of reading in a large number of orthographies, it is as yet unclear whether the predictive patterns are universal or language specific. This was examined in a longitudinal study across Grades 1 and 2 with 1,120 children acquiring one of five alphabetic orthographies with different degrees of orthographic complexity (English, French, German, Dutch, and Greek). Path analyses revealed that a universal model could not be confirmed. When we specified the best-fitting model separately for each language, RAN was a consistent predictor of reading fluency in all orthographies, whereas the association between PA and reading was complex and mostly interactive. We conclude that RAN taps into a language-universal cognitive mechanism that is involved in reading alphabetic orthographies (independent of complexity), whereas the PA–reading relationship depends on many factors like task characteristics, developmental status, and orthographic complexity. 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

The majority of children and adults with reading disabilities exhibit pronounced difficulties on naming-speed measures such as tests of rapid automatized naming (RAN). RAN tasks require speeded naming of serially presented stimuli and share key characteristics with reading, but different versions of the RAN task vary in their sensitivity: The RAN letters task successfully predicts reading ability, whereas the RAN objects task does not reliably predict reading after kindergarten. In this study we used functional magnetic resonance imaging to evaluate the neural substrates that may underlie performance on these tasks. In two scans during the same test session, adult, average readers covertly rapidly named objects or letters or passively viewed a fixation matrix of plus signs. For both rapid naming tasks compared with fixation, activation was found in neural areas associated with eye movement control and attention as well as in a network of structures previously implicated in reading tasks. This reading network included inferior frontal cortex, temporo-parietal areas, and the ventral visual stream. Whereas the inferior frontal areas of the network were similarly activated for both letters and objects, activation in the posterior areas varied by task. The letters task caused greater activation in the angular gyrus, superior parietal lobule, and medial extrastriate areas, whereas object naming only preferentially activated an area of the fusiform gyrus. These results confirm that RAN tasks recruit a network of neural structures also involved in more complex reading tasks and suggest that the RAN letters task specifically pinpoints key components of this network. 相似文献

We examined the relationship between rapid automatized naming (RAN) components—articulation time and pause time—and reading fluency across languages varying in orthographic consistency. Three hundred forty-seven Grade 4 children (82 Chinese-speaking Taiwanese children, 90 English-speaking Canadian children, 90 Greek-speaking Cypriot children, and 85 Finnish-speaking children) were assessed on RAN (colors and digits) and reading fluency (word reading efficiency and text reading speed). The results showed that articulation time accounted for more unique variance in reading in the alphabetic orthographies than in Chinese, and pause time for more unique variance in reading in Chinese than in alphabetic orthographies. If automaticity in RAN is manifested with a higher contribution of articulation time to reading fluency than pause time and with a strong relationship between articulation time and pause time, then our findings suggest that automaticity in RAN is reached earlier in alphabetic orthographies than in Chinese. 相似文献
