The longitudinal project attempts to estimate the parameters of a priori postulates with their measurement errors, and the goodness-of-fit of model-implied population covariance sigma matrices with observed sample covariance matrices, using linear structural equation modelling (LISREL). The present report deals with Phase 2 of the project (see Leong 1988 for Phase 1 results) and involved 252 ten-to twelve-year-old readers. Three latent exogenous components were postulated: (a) orthographic/phonological component, (b) morphological component, and (c) sentence comprehension component. These constructs were subserved by 8 measurable indicators (5 lexical decision and 3 vocalization tasks). These 8 independent tasks were all administered on-line via the microcomputer under laboratory conditions with combined, scaled accuracy and latency measures as indices of efficiency in processing the reading related tasks. The latent endogenous or dependent component Reading Performance was subserved by standardized vocabulary and reading comprehension tests. Maximum likelihood analyses using LISREL VI to test the approximation of the hypothesized model show a good fit for the grade 4 data, a reasonable fit for grade 5, and a less unambiguous fit for grade 6. These results are generally confirmed with the simultaneous structural analyses of Phase 2 and Phase 1 (N=298 students) multisamples. Multi-components and multi-levels of reading for these age groups are emphasized.  相似文献

Adults enrolled in basic education exhibit poor academic performance, often reading at elementary and middle-school levels. The current study investigated the similarities and differences of reading skills and eye movement behavior between a sample of 25 low-skilled adult readers and 25 first grade students matched on word reading skill. t tests for matched pairs found no significant differences on language comprehension, reading comprehension, or eye movement variables. Regression analyses revealed that language comprehension made greater contributions to reading comprehension for adults (verses children) in the simple view of reading model. Processing time (gaze duration) was found to account for unique variance in both passage reading comprehension and sentence comprehension efficiency after controlling for word reading and language skills for adults. For children, processing time was only a significant predictor for sentence comprehension efficiency.  相似文献

This study aims to investigate the relation of syntactic and discourse skills to morphological skills, rapid naming, and working memory in Chinese adolescent readers with dyslexia and to examine their cognitive–linguistic profiles. Fifty-two dyslexic readers (mean age, 13;42) from grade 7 to 9 in Hong Kong high schools were compared with 52 typically developing readers of the same chronological age (mean age, 13;30) in the measures of word reading, 1-min word reading, reading comprehension, morpheme discrimination, morpheme production, morphosyntactic knowledge, sentence order knowledge, digit rapid naming, letter rapid naming, backward digit span, and non-word repetition. Results showed that dyslexic readers performed significantly worse than their peers on all the cognitive-linguistic tasks. Analyses of individual performance also revealed that over half of the dyslexic readers exhibited deficits in syntactic and discourse skills. Moreover, syntactic skills, morphological skills, and rapid naming best distinguished dyslexic from non-dyslexic readers. Findings underscore the significance of syntactic and discourse skills for understanding reading impairment in Chinese adolescent readers.  相似文献

This study explored the background knowledge (BK) and reading comprehension (RC) relationship for struggling adult readers. Using confirmatory factor analyses, a single-factor BK model exhibited better fit than a two-factor model separating academic knowledge and general information, which indicates that BK represents a unidimensional construct for this population. In addition, one measure of oral vocabulary loaded with a latent factor of BK, which was separable from a latent factor of two additional oral vocabulary subtests. Using structural equation modeling, we found that BK exhibited a direct effect on RC after controlling for participants’ grade level, decoding, listening comprehension, and oral vocabulary.  相似文献

In this study, we explored the relationship between beginning readers' phonological awareness and other aspects of phonological processing, specifically as manifested in short-term memory and comprehension tasks. The theoretical questions underlying the study were (a) what roles phonological processes play in children's beginning reading, from word identification through sentence comprehension, and (b) whether those roles are sufficiently related that potential difficulties at one level directly affect processing at other levels. Phonologically induced effects were observed for word-list memory and for sentence judgments for both novice readers (at the end of kindergarten) and relatively more experienced readers (end of Grades 1 and 2). For both age groups, correlational analyses revealed relationships among phonological awareness, phonological processing in list memory, and word reading. However, phonological processing in sentence comprehension was not related to other types of phonological processing. These results indicate that although phonology plays a role during comprehension, phonological processing may not be as limiting a factor in comprehension as in word reading.  相似文献

In the present study we investigated developmental relations among word reading fluency, listening comprehension, and text reading fluency to reading comprehension in a relatively transparent language, Korean. A total of 98 kindergartners and 170 first graders in Korea were assessed on a series of tasks involving listening comprehension, word reading fluency, text reading fluency, and reading comprehension. Results from multigroup structural equation models showed that text reading fluency was a dissociable construct from word reading fluency for both kindergartners and first graders. In addition, a developmental pattern emerged: listening comprehension was not uniquely related to text reading fluency for first graders, but not for kindergartners, over and above word reading fluency. In addition, text reading fluency was uniquely related to reading comprehension for kindergartners, but not for first graders, after accounting for word reading fluency and listening comprehension. For first graders, listening comprehension dominated the relations. There were no differences in the pattern of relations for skilled and less skilled readers in first grade. Results are discussed from a developmental perspective for reading comprehension component skills including text reading fluency.  相似文献

Ninety-six children were administered an orthographic test as preschoolers and two measures of nonphonemic phonological awareness (syllable segmentation, rhyme detection) in midkindergarten. The power of the three measures to predict reading at grades 1, 3, and 7 was examined. With earlier reading level, preschool verbal IQ and age, and verbal memory controlled, both phonological measures added significant variance to grade 1 word reading, and syllable segmentation also contributed to reading comprehension, but neither measure accounted for variance in reading at grades 3 and 7. The orthographic measure contributed significant variance to grade 1 word reading, and also to reading vocabulary and reading comprehension at grades 3 and 7, with the proportion of variance in reading comprehension increasing with grade level. When early (grade 1) and late (grade 7) poor readers were compared, late poor readers were significantly higher than early poor readers on a first grade phonological test, but significantly lower on a seventh grade orthographic measure. Evidence suggested that a late reading comprehension deficit may be due to poor orthographic processing skills in some children, but to a phonological and general verbal deficit in others.  相似文献

To become skillful readers, children have to acquire the ability to translate printed words letter by letter into phonemic representations (phonological recoding) and the ability to recognize the written word forms holistically (orthographical decoding). Whereas phonological recoding is the key for learning to read and useful for recognizing unknown or low-frequent words, orthographical decoding is often more efficient and takes less time, thus facilitating reading processes on the sentence and text level. Several studies with English-speaking children provided evidence for the relevance of the two routes but the question whether and to what extent both word recognition skills contribute to reading comprehension in young German readers requires further clarification. Based on data from a cross-sectional study with German primary school children we investigated whether and to what extent both types of word recognition skills are associated with sentence (N = 666) and text comprehension skills (N = 149) and how these relationships develop from Grade 2 to 4. The results indicate that both phonological recoding skills and orthographical decoding skills are important for reading comprehension skills. Their relative weight does not change across grade levels.  相似文献

The current study examined the relations among key variables that underlie reading comprehension of expository science texts in a diverse population of adult native English readers. Using Mechanical Turk to sample a range of adult readers, the study also examined the effect of text presentation on readers’ comprehension and knowledge structure established after reading. In Study 1, ratings of situational interest, select reading background variables, and select measures of readers’ knowledge structure accounted for significant variance in comprehension. In Study 2, the knowledge structure metrics of primacy, recency, and node degree as well as several text ratings were found to be comparable across text presentation formats. Participants who read the text sentence-by-sentence obtained higher scores on measures of comprehension and provided higher ratings of situational interest than those who received the whole paragraph text at once. Knowledge structure measures for the sentence-by-sentence and paragraph formats were similar (68% overlap). We discuss implications for future research examining factors that underlie the successful comprehension of science texts.  相似文献

The current study examined statistically significant differences between struggling and adequate readers using a multicomponent model of reading comprehension in 796 sixth through eighth graders, with a primary focus on word reading and vocabulary. Path analyses and Wald tests were used to investigate the direct and indirect relations of word identification, vocabulary, silent reading efficiency, and inference-making on reading comprehension. Comparing struggling versus adequate comprehenders revealed statistically significant differences in path coefficients. In both groups, vocabulary had the largest total effect when considering its direct and indirect effects. Word identification was the strongest direct predictor for struggling comprehenders (β = .18 for struggling vs. β = ? .03 for adequate), while vocabulary was the strongest predictor for adequate comprehenders (β = .40 for adequate vs. β = .14 for struggling). Findings reinforce (a) vocabulary knowledge plays a primary role in explaining individual differences in adolescent reading comprehension, (b) the need to differentiate intervention to address underlying difficulties of struggling readers, and (c) the relations of reading component skills (e.g., word reading and silent reading efficiency) to reading comprehension may be different based on reader proficiency.  相似文献

According to the simple view of reading (SVR), reading comprehension relies on “decoding” (pseudoword, word reading) and “oral comprehension” skills. Testing 556 French pupils, we aimed at unpacking these two components and tracking their longitudinal development in first grade. We have found that: (1) lower level language skills (vocabulary, syntax) and discourse skills (oral text comprehension) emerged as two dimensions of “oral comprehension”; (2) lower level language skills longitudinally predicted reading comprehension outcomes, above code-related skills; (3) decoding precursors (letter knowledge, naming speed and phonemic awareness) predicted reading comprehension directly, and indirectly, through decoding skills (pseudoword, word reading, text reading fluency); (4) Oral comprehension skills did not favour the development of decoding. Our results support the independency of the SVR components. However, we suggest that a more fine-grained conceptualisation of oral comprehension skills would help to better understand the individual and pedagogical factors influencing the early development of reading comprehension.  相似文献

This study explored subprocesses of reading for 157 fifth grade Spanish-speaking English language learners (ELLs) by examining whether morphological awareness made a unique contribution to reading comprehension beyond a strong covariate-phonological decoding. The role of word reading and reading vocabulary as mediators of this relationship was also explored. Results showed that fourth grade morphological awareness did not make a significant unique direct effect on fifth grade reading comprehension, controlling for phonological decoding, word reading, and reading vocabulary. Fourth grade morphological awareness did, though, make a unique moderate total contribution to fifth grade reading comprehension with reading vocabulary, but not word reading, mediating the relationship when controlling for phonological decoding. In contrast, phonological decoding made a nonsignificant total contribution to reading comprehension with neither word reading nor reading vocabulary mediating the relationship when controlling for morphological awareness. Alternative models were also explored, showing the importance of including both predictors in a model of ELL reading comprehension, primarily to include the support of phonological decoding to word reading and the support of morphological awareness to reading comprehension via reading vocabulary. Results highlighted the importance of morphological awareness in facilitating reading comprehension via improving reading vocabulary knowledge, and also the potential of interventions involving morphological instruction to support reading achievement for Spanish-speaking ELLs.  相似文献

Less-skilled readers may experience a processing bottleneck in reading comprehension produced by a failure to automate word recognition. The automaticity hypothesis predicts that training which increases rapid and automatic word recognition will improve comprehension. To date few studies have tested this hypothesis. Our goal was to test the automaticity hypothesis by training dyslexic readers (n=35) to access the meaning of words more rapidly. Training consisted of speeded word games implemented on a microcomputer that provided feedback concerning subjects’ speed and accuracy using sound and graphics. Three experimental tasks were administered both before and after training in which trials with trained and untrained stimuli were randomly intermixed. The measures were latency and accuracy of word vocalization, sentence comprehension, and a dual-task procedure designed to measure automaticity. Although pre/post improvement was larger for trained than untrained stimuli, reaction time on the word vocalization and sentence comprehension tasks improved significantly for both trained and untrained stimuli. In contrast, automaticity and sentence comprehension accuracy improved significantly for trained but not untrained stimuli. The training effect in comprehension remained when controlling for increases in word knowledge. The results support the automaticity hypothesis and further suggest that severely disabled readers may benefit from training in automatic word recognition. A portion of this research was supported by a Faculty Development Grant awarded to the first author from Southeastern Louisiana University. Directed by the second author, the Los Angeles study was based on a doctoral dissertation submitted by the first author to the University of Southern California in partial fulfillment of the requirements for the Ph.D. degree. Portions of this work were presented at the meetings of the Society for Research in Child Development, Baltimore, April 1989, and The Orton Dyslexia Society, Portland, November 1991.  相似文献

Two experiments demonstrate that individual differences among normal adult readers, including lexical quality, are expressed in silent reading at the word level. In the first of two studies we identified major dimensions of variability among college readers and among words using factor analysis. We then examined the effects of these dimensions of variability on eye movements during paragraph reading. More experienced readers (who also were higher in reading speed) read words more quickly, especially less frequent words, while readers with higher lexical knowledge showed shorter early fixations, especially for more frequent words. These results suggest that individual differences in reading may reflect differences in the quality of lexical representations and in reading experience, which is a source of lexical quality. In a second study, we controlled the lexical knowledge readers obtained from new words through a training paradigm that varied exposure to a word’s orthographic, phonological, and meaning constituents. Training exposure to orthographic and phonological constituents affected first pass reading measures, and phonological and meaning training affected second pass measures. Incomplete knowledge of word components slowed first pass reading times, compared to both more complete knowledge and no knowledge. Training effects were mediated by individual differences, pointing to lexical quality and reading experience—which, combined reflect reading expertise—as important in word reading as part of text reading.  相似文献

This study investigated the hypothesis that the contributions of oral language comprehension (C) and word recognition (D) to reading comprehension (R) in the simple view of reading (SVR) are not independent because a component of C (vocabulary knowledge) directly contributes to the variance in D. Three analysis procedures (hierarchical regression analysis, exploratory factor analysis, and structural equation modeling) were used to analyze data obtained from a sample (N = 122) of 7-year-old students who were administered tests of vocabulary knowledge, nonword reading, word recognition (two standardized tests), and parallel forms of listening and reading comprehension. Results from the regression analysis indicated that vocabulary made a contribution to R beyond that made by word recognition and listening comprehension; results from the exploratory factor analysis showed that two factors (Decoding and Linguistic Comprehension) were extracted, with vocabulary and listening comprehension loading highly on the Linguistic Comprehension factor; and results from structural equation modeling revealed that the latent construct, C, influenced R not only directly but also indirectly through the latent construct, D.  相似文献

This study examined individual differences among beginning readers of English as a foreign language (EFL). The study concentrated on the effects of underlying first language (L1) knowledge as well as EFL letter and vocabulary knowledge. Phonological and morphological awareness, spelling, vocabulary knowledge, and word reading in Hebrew L1, in addition to knowledge of EFL letters and EFL vocabulary, were measured. The study also investigated the effect of socioeconomic background (SES) on beginning EFL readers. Participants included 145 fourth graders from three schools representing two socioeconomic backgrounds in the north of Israel. The results indicate that knowledge of English letters played a more prominent role than knowledge of Hebrew L1 components in differentiating between strong and weak EFL readers. The Linguistic Coding Differences Hypothesis was supported by L1 phonological awareness, word reading, and vocabulary knowledge appearing as part of discriminating functions. The presence of English vocabulary knowledge as part of the discriminant functions provides support for English word reading being more than just a decoding task for EFL beginner readers. Socioeconomic status differentiated the groups for EFL word recognition but not for EFL reading comprehension.  相似文献

The present study investigated proximal and distal predictors of reading comprehension by including latent factors such as alphabet knowledge, phonological awareness, semantic knowledge, word reading, oral reading fluency, and reading comprehension. The sample consisted of 79 five-year-old Korean-monolingual children who were assessed at the end of the school year. The results showed that alphabet knowledge, phonological awareness, and semantic knowledge latent variables were all positively and highly related to word-reading skills, but phonological awareness made a unique contribution above and beyond alphabet knowledge and semantic knowledge. Word reading was highly related to oral reading fluency and directly related to reading comprehension. Oral reading fluency, although a separate construct from word reading accuracy, was not uniquely related to reading comprehension after accounting for the effects of word reading and semantic knowledge. Semantic knowledge was fairly strongly and uniquely related to reading comprehension.  相似文献

The integration of knowledge during reading was tested in 1,109 secondary school students. Reading times for the second sentence in a pair (Jane’s headache went away) were compared in conditions where the first sentence was either causally or temporally related to the first sentence (Jane took an aspirin vs. Jane looked for an aspirin). Mixed-effects explanatory item response models revealed that at higher comprehension levels, sentences were read more quickly in the causal condition. There were no condition-related reading time differences at lower comprehension levels. This interaction held with comprehension- and inference-related factors (working memory, word and world knowledge, and word reading efficiency) in the models. Less skilled comprehenders have difficulty in knowledge-text integration processes that facilitate sentence processing during reading.  相似文献

Because of the research demonstrating the roles of phonological awareness, serial naming speed, and orthographic processing in reading, a test of each of these skills was added to a preschool screening battery. The main aim of the study was to determine whether these measures would contribute to the prediction of reading. The 118 subjects were first tested six months before kindergarten entry and were followed up 19 and 24 months later. Each additional screening test made a significant, independent contribution to the prediction of early first grade word reading/spelling, after the contributions of a parent rating of preschool reading ability (PRA), verbal IQ, socio-economic status (SES), and chronological age were accounted for. With letter naming and PRA, the additional tests were responsible for 62 percent of the variance. The orthographic test made the largest single contribution (32%) to the variance in word reading/spelling. Variables contributing significantly to the prediction of later first grade reading comprehension were (in order of proportion of the variance accounted for) letter naming, sentence memory, object naming speed, the orthographic test, and SES. The revised preschool screening battery correctly identified 91 percent of individual first grade good and poor readers. It was concluded that preschool measures of phonological awareness, serial naming speed, and orthographic processing make a strong contribution to prediction of first grade reading.  相似文献

Predictors of early word reading are well established. However, it is unclear if these predictors hold for readers across a range of word reading abilities. This study used quantile regression to investigate predictive relationships at different points in the distribution of word reading. Quantile regression analyses used preschool and kindergarten measures of letter knowledge, phonological awareness, rapid automatised naming, sentence repetition, vocabulary and mother's education to predict first‐grade word reading. Predictors generally varied in significance across levels of word reading. Notably, rapid automatised naming was a significant unique predictor for average and good readers but not poor readers. Letter knowledge was generally a stronger unique predictor for poor and average readers than good readers. Well‐known word reading predictors varied in significance at different points along the word reading distribution. Results have implications for early identification and statistical analyses of reading‐related outcomes. What is already known about this topic
  • Early predictors of word reading are well established, with letter knowledge, phonological awareness and rapid automatised naming identified as key predictors.
  • These relationships are primarily investigated in average readers, or in groups of good and poor readers separated by an arbitrary cut‐off score.
What this paper adds
  • In this study, we used quantile regression to determine significant predictors of word reading across a range of word reading abilities.
  • The quantile regression approach avoids the loss of power that can arise when creating subgroups and has none of the issues associated with the use of a single, arbitrary cut-off score to separate good and poor readers.
  • Letter knowledge and phonological awareness were significantly predictive of word reading across the distribution of word reading abilities, whereas rapid automatised naming was significant only for good readers, and sentence recall was significant only for poor readers.
Implications for theory, policy and practice
  • Results reinforce the usefulness of measures such as letter knowledge, phonological awareness and sentence repetition in the early identification of children at risk for reading disabilities.
  • Results also suggest that measures of rapid naming may add little unique information in differentiating between children who subsequently read in the below‐average range.
