This study explores 1) the components of rapid automatized naming (RAN) by first analyzing the factorial associations between RAN tasks and various nonword decoding and processing speed measures and secondly, by exploring which of these process latent variables are uniquely associated with literacy in 65 below-average readers and spellers. In preliminary factor analyses, all speeded naming tasks loaded together (Factor 1: Rapid Naming); All tasks involving speeded alphanumeric naming loaded together (Factor 2: Alphanumeric Naming); Alphanumeric RAN tasks also loaded with nonsense word decoding (Factor 3: Decoding). The Alphanumeric Naming factor predicted 2% of unique variance in Literacy. Our results thus provide two new findings: 1) only very modest variation in Literacy is explained by aspects of RAN not primarily associated with either generic naming speed or decoding ability; 2) variation in other verbal forced choice response speed and response inhibition tasks are linked to reading through common variance in speeded naming tasks also shared by alphanumeric RAN tasks. Implications of these findings for theories of reading and individual differences are explored.  相似文献

Rapid automatized naming (RAN) is associated with children's arithmetic performance, which is multifactorial by nature and consists of arithmetic fluency, arithmetic procedure, and word problems. Yet, it is unclear whether RAN can predict all key aspects of arithmetic skills independently and what cognitive mechanisms may explain this relation. Using a sample of Chinese primary school students (N = 170), results showed that while RAN was associated with all key aspects of arithmetic skills, the relations of RAN–arithmetic procedure and RAN–word problems may be dependent on that of RAN–arithmetic fluency. Supporting the processing speed hypothesis, results further suggested that processing speed may underlie the relation between RAN and arithmetic performance. Findings made unique contribution to understanding the effect of RAN on arithmetic performance and cognitive mechanisms that may underpin this association in the context of Chinese culture.  相似文献

Three continuous rapid naming tasks (Semel, Wiig, & Secord, 1995) were administered to 2,450 American, English-speaking, academically achieving individuals with typical language development and intellectual ability (ages 6 to 21 years) and 136 individuals with primary language disorders (LD; ages 6, 7, 9, 11, 12, 15-16). Naming time in seconds differed significantly (p < .01) between the groups for color naming (Task 1) at age 12, shape naming (Task 2) at age 6, and color-shape naming (Task 3) at ages 6, 7, 9, and 12. Naming accuracy did not differ significantly (p > .01) between groups at the majority of the age levels compared. In the normative group, naming speed increased with age in a monotonic progression. The developmental trajectory in the LD group was essentially parallel, but elevated. The percentages of individuals who failed the naming-time criteria for Task 3 (color-shape naming) differed significantly in the two groups at all ages compared (p < .05). These findings indicate that the requirements for two-dimensional, continuous naming (Task 3 color-shape naming) resulted in reduced naming speed (longer total times) and interference with fluency in language production in about half of the clinical sample.  相似文献

It is widely accepted that deficits in phonological awareness skills are related to reading difficulties. Recently, another source of reading difficulty has been identified that involves naming speed, and combined impairments in phonological skills and naming speed will produce more severe reading deficits than single deficits in either of these cognitive skills. The purpose of this study was to investigate the consequences of grouping children based on the presence or absence of deficits in these skills. We demonstrate that the greater severity of reading impairment found in children with a double deficit could be due in part to a statistical artifact caused by grouping children based on their performance on two correlated continuous variables. This artifact also makes it difficult to establish the relative impact of deficits in naming speed on reading ability independent of deficits in phonological awareness.  相似文献

The present study investigated whether orthographic depth can increase the bias towards multi-letter processing in two reading-related skills: visual attention span (VAS) and rapid automatized naming (RAN). VAS (i.e., the number of visual elements that can be processed at once in a multi-element array) was tested with a visual 1-back task and RAN was measured in a serial letter naming task that introduced a novel manipulation (some letter sequences formed frequent words). Spanish-Basque and French-Basque bilingual children were tested at early (30 children in 1st and 2nd grade), and more advanced (24 children in 3rd, 4th and 5th grade) stages of reading acquisition to investigate whether they would be differently biased towards multi-letter processing due to reading in two shallow (Spanish, Basque), or a deep and a shallow (French, Basque) orthography. The French-Basque bilinguals, who read in a deep orthography, were expected to rely on larger orthographic units in reading and thus to be more biased towards multi-letter processing in both tasks. This was expected to be reflected by: (a) a uniform distribution of attention across letter strings in the VAS task, and (b) a greater interference of the embedded words on letter-by-letter naming in RAN, leading to longer naming times. The expected group differences were observed in the more advanced readers, with French-Basque bilinguals showing a wider distribution of VAS across letter strings and longer naming times in RAN.  相似文献

Deaf readers often fail to achieve age-appropriate reading levels. In hearing children, two cognitive factors correlated with reading delay are phonological awareness and decoding (PAD) and rapid automatized naming (RAN) of visual material. In this study we explored the contribution of these factors to reading and reading delay in a sample of deaf students (N = 49, mean age 13 years) whose reading age (RA) was around 7 years. Although PAD performance was poor in the deaf students compared with RA-matched hearing controls, it nevertheless correlated with their RA. Whether tested in sign or speech, RAN was much faster in the deaf group than in RA-matched hearing controls but showed no direct relationship with reading level or reading delay. We conclude that in contrast to PAD, which is a factor in both deaf and hearing reading achievement, RAN may be only indirectly related to reading in deaf students.  相似文献

Longitudinal course of rapid naming in disabled and nondisabled readers   总被引:1,自引:0,他引:1  
The Rapid Automatized Naming Test (Denckla and Rudel 1974) was studied cross-sectionally in an sample of kindergartners (n=342) at-risk for reading disability (Study 1), and longitudinally in an n=160 epidemiological normal sample of children tested in first, third, fifth, and eighth grades (Study 2). Study 1 showed faster absolute naming speeds for those with near perfect untimed alphabet recitation, but the stronger and more orderly relation (at r=.31, p<.0001) was between three levels of alphabet recitation accuracy and the relative number/letter naming speed advantage (ratio of mean number/letter naming speed minus mean color/object naming speed over mean color/object naming speed). In Study 2, the number/letter advantage was already strongly present by first grade, and did not increase significantly thereafter, but absolute naming times improved steadily across grades in an exponential decay function. In this sample, the relative number/letter advantage was not related to reading level. However, the absolute color/object naming speed was strongly related to reading level and vocabulary across grades. Norms for the Rapid Automatized Naming Test based on the epidemiological normal sample tested in Grades 1, 3, 5, and 8 are presented in the appendix.  相似文献

A study of the concurrent relationships between naming speed, phonological awareness and spelling ability in 146 children in Years 3 and 4 of state‐funded schools in South‐East England (equivalent to US Grades 2 and 3) is reported. Seventy‐two children identified as having normal phonological awareness but reduced rapid automatised naming (RAN) performance (1 standard deviation below the mean) participated in the study. A group of 74 children was further identified. These children were matched on phonological awareness, verbal and nonverbal IQ and visual acuity, but all members of this group showed normal RAN performance. RAN made a significant unique contribution to spelling performance. Further analyses showed that participants with low naming performance were significantly poorer spellers overall and had a specific difficulty in spelling irregular words. The findings support the view that RAN may be indexing processes that are implicated in the establishment of fully specified orthographic representations.  相似文献

This study was designed to investigate potential reading differences between low-achieving and typically achieving first-grade Korean-speaking children by (1) comparing their speed of lexical access on alphanumeric and non-alphanumeric tests of rapid automatized naming and (2) comparing relationships between the two groups’ performance on alphanumeric and non-alphanumeric tasks with their performance on component measures of reading. Twenty-seven low-achieving readers and 34 typically achieving readers participated in this study. The low-achieving readers performed significantly more slowly than their typically achieving reading peers on the four measures of rapid naming. The response rates for both alphanumeric naming tasks (digits and letters) showed strong negative correlations with oral reading fluency, while their response rates for the non-alphanumeric naming tasks (Color and Object naming) showed relatively weak relationships with reading measures for both groups. In regression equations, Letter naming tasks were uniquely associated with both word recognition and oral reading fluency. The utility of using alphanumeric naming tasks as indicators for identifying Korean Hangul readers who are at risk for reading disabilities is discussed.  相似文献

It is well established that rapid automatised naming (RAN) correlates with reading ability. Despite several attempts, no single component process (mediator) has been identified that fully accounts for the correlation. The present paper estimated the explanatory value of several mediators for the RAN–reading correlation. One hundred and sixty‐nine preschool students were given measures of RAN and additional measures of phonological awareness, lexical search speed, letter knowledge and paired associate learning. Their reading skills were tested a year later along with speed of processing. The influence of the mediators on the RAN–reading correlation was estimated as indirect effects in mediation analyses. Phonological awareness and letter knowledge significantly mediated the RAN–reading relationship, each accounting for a moderate part of the correlation between RAN and reading fluency. Thus, the RAN–reading correlation was partly, but not fully, accounted for by precursors of reading that are currently known.  相似文献

This study compared the performance of children with reading disability (RD) and normal reading achievement (NRA) on tasks of serial rapid naming, verbal fluency, letter-based word retrieval, and articulatory speed. The groups, composed of children at two discrete age levels, one younger and one older, were matched for age, gender, and neighborhood school. Analyses of the on-line measurement of the children’s serial rapid naming indicated that the children with RD had significantly larger reaction times and production durations than their NRA peers despite similar levels of accuracy. They also performed significantly worse on the categorical verbal fluency task, the letter-based word retrieval task, and the test of articulatory speed. The findings suggest that both access and post-access processes, such as oral-motor inefficiency that extends the duration of word production, may be implicated in the slower serial rapid naming that has typified many samples of children with RD.

The present study assesses the genetic and environmental etiologies of reading, rapid naming (RN), and their covariation by fitting multivariate structural equation models to data from 587 twin pairs in which at least one member of the pair exhibited reading difficulties (low-range) and from 360 control (normal-range) twin pairs who were tested in the Colorado Learning Disabilities Research Center. Results from a bivariate phenotypic analysis with two hypothesized latent factors, READ and RN, indicated that the correlation between reading and rapid naming performance for the low-range sample was significantly higher than that of the normal-range sample. When this model was partitioned to include estimates of genetic, shared environmental, and nonshared environmental influences, resulting heritability estimates did not differ significantly for the low-range and normal-range samples for either READ or RN. However, similar to the phenotypic correlation, the genetic correlation between the READ and RN latent factors could not be equated for the two groups. Thus, the etiology of the relationship between reading performance and rapid naming may differ for children with reading difficulties and normally-achieving readers. Moreover, these results support previous findings that the best predictors of reading skills may differ for samples of children with normal reading levels and those with reading difficulties.  相似文献

This study investigated the role of speed of processing, rapid naming, and phonological awareness in reading achievement. Measures of response time in motor, visual, lexical, grammatical, and phonological tasks were administered to 279 children in third grade. Measures of rapid object naming, phonological awareness, and reading achievement were given in second and fourth grades. Reading group comparisons indicated that poor readers were proportionally slower than good readers across response time measures and on the rapid object naming task. These results suggest that some poor readers have a general deficit in speed of processing and that their problems in rapid object naming are in part a reflection of this deficit. Hierarchical regression analyses further showed that when considered along with IQ and phonological awareness, speed of processing explained unique variance in reading achievement. This finding suggests that a speed of processing deficit may be an "extraphonological" factor in some reading disabilities.  相似文献

This study investigated the relative importance of semantic, grammatical, phonological, and rapid naming abilities in predicting word identification in a large, representative sample of children enrolled in first through sixth grade, using correlation, factor analysis, multiple regression, and predictive outcome analysis techniques. Composite measures of these abilities were found to correlate significantly with word identification, even after controlling for the effects of nonverbal intelligence. Factor analysis indicated that the spoken language composites and the word identification composite loaded on one factor, whereas the perceptual speed composites loaded on a second factor. Multiple regression analyses showed that among younger children in the early stages of learning to read and children whose word identifying skills were below average, the phonology and rapid naming composites accounted for the most variance in predicting word identification skills. Among older children and children who were proficient in word identification, the semantics composite accounted for the most variance. The most important analyses in this study (i.e., the calculations of the sensitivity indexes, the specificity indexes, and the positive predictive values) evaluated the practical value of using the composites to predict poor word identification skills in children. To be considered practically useful, all predictive outcome values had to be .75 or greater. None of the composites studied, including an application of the double-deficit hypothesis, met this criterion. The results from this study question the accuracy and utility of using any of the abilities studied to predict which students are at risk for or have poor word identification skills.  相似文献

Even though researchers have established that rapid serial naming (RSN), or the ability to name within a restricted category of visual stimuli quickly, is a significant predictor of word reading, the predictive nature of RSN is not well understood. To investigate the relationship of RSN and other variables thought to contribute to beginning word reading (phonological awareness, orthographic knowledge, memory span, processing speed, and articulation), a preliminary/exploratory model of word reading was developed and then tested by path analysis. Results indicated that no variable in the model could fully `explain' RSN; processing speed, but not articulation, contributed to RSN performance. RSN and orthographic knowledge were significantly related, but this relationship was due to the effects of processing speed. In terms of their unique contributions to the variance in word reading, RSN, phonological awareness, and orthographic knowledge were independent of each other. While these results pertain only to normal readers and are preliminary in nature, they may provide a basis for a clear interpretation of similar studies conducted with both normal and dyslexic readers.  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

The present study examined the relationship of phonological awareness, naming speed, and verbal memory to the scores obtained from five tests assessing word attack, word identification, reading comprehension, and spelling skills in 54 children with severe reading disabilities (48 boys and 6 girls; M age = 9 years, 7 months). Multiple regression analyses indicated that the best predictor of achievement across the five academic tests was the Verbal Comprehension factor from the Wechsler Intelligence Scale for Children-Revised. Age, socioeconomic status (SES), and externalizing behavior problems were also significant predictors of achievement, depending on the academic measure. After controlling for age, SES, behavior problems, and intelligence, the phonological awareness task added significantly to the prediction of word attack, spelling, and reading comprehension scores; rapid letter naming added significantly to the prediction of word identification and prose passage speed and accuracy scores; and a word-list memory task added significantly to the prediction of word recognition scores. These results suggest that several independent processes interact to determine the extent and severity of reading problems.  相似文献

本文认为中国现代话剧现实主义创作精神 ,是创作主体在政治思维定势的作用下 ,对西方十九世纪以来现实主义戏剧的历史性误读中生成 ,并在反帝反封建革命斗争烈火燃烧的中国土地上发展、定型的。处于这种规定情境中的创作主体格外倚重政治功利性而相对轻视客观真实性 ,并因此造就了中国现实主义话剧的群体意识、未来情结和历史乐观主义等特殊品格。研究政治思维定势与中国现代话剧现实主义精神的关系 ,不仅能够更深入地发现对象内在的历史规定性 ,而且也有助于深化人们对政治思维与文学创造之关系的规律性的认识。  相似文献
