In a cross-sectional study, we examined the relationship between the quality of lexical representations and text comprehension skill in German primary school children (Grades 1–4). We measured the efficiency and accuracy of orthographical, phonological, and meaning representations by means of computerized tests. Text comprehension skill was assessed with a standardized reading test with questions requiring recognition of text information and inferencing. Both the accuracy of and the efficiency of access to the three types of lexical representations contributed to explaining interindividual variation in text comprehension skill. Results from a path-analytic model suggest a specific causal order of the three components of lexical quality with the quality of meaning representations partly mediating the effects of form representations.  相似文献

Adults of varying reading comprehension skill learned a set of previously unknown rare English words (e.g., gloaming) in three different learning conditions in which the type of word knowledge was manipulated. The words were presented in one of three conditions: (1) orthography-to-meaning (no phonology); (2) orthography-to-phonology (no meaning); and (3) phonology-to-meaning (no orthography). Following learning, participants made meaning judgments on the learned words, familiar known words, and unpresented (unlearned) rare words while their ERPs were recorded. The behavioral results showed no significant effects of comprehension skill on meaning judgment performance. Contrastingly, the ERP results indicated comprehension skill differences in P600 amplitude; high-skilled readers showed stronger familiarity effects for learned words, whereas less-skilled readers did not distinguish between learned words, familiar words, and unlearned words. Evidence from the P600 and N400 illustrated superior learning of meaning when meaning information was coupled with orthography rather than phonology. These results suggest that the availability of word knowledge (orthography, phonology, and meaning) at learning affects subsequent word identification processes when the words are encountered in a new context.  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 compared orthographic and semantic aspects of word learning in children who differed in reading comprehension skill. Poor comprehenders and controls matched for age (9–10 years), nonverbal ability and decoding skill were trained to pronounce 20 visually presented nonwords, 10 in a consistent way and 10 in an inconsistent way. They then had an opportunity to infer the meanings of the new words from story context. Orthographic learning was measured in three ways: the number of trials taken to learn to pronounce nonwords correctly, orthographic choice and spelling. Across all measures, consistent items were easier than inconsistent items and poor comprehenders did not differ from control children. Semantic learning was assessed on three occasions, using a nonword–picture matching task. While poor comprehenders showed equivalent semantic learning to controls immediately after exposure to nonword meaning, this knowledge was not well retained over time. Results are discussed in terms of the language and reading skills of poor comprehenders and in relation to current models of reading development.  相似文献

Electrophysiology studies have identified two event‐related potentials that are modulated by predictive processes during language comprehension: the N400 and a frontal positivity. The N400 is smaller when words are presented within highly restrictive sentences, indicating reduced lexical retrieval costs. Violations of strong predictions generate larger frontal positivities, possibly reflecting inhibitory processes. More skilled comprehenders may exhibit enhanced predictive processing, but this possibility has seldom been investigated with event‐related potentials (ERPs). We analyzed the association between predictability ERP modulations and reading comprehension abilities. Twenty‐four undergraduate students were exposed to strongly and weakly constraining sentences, ending with an expected or unexpected final word. Their comprehension skills were assessed with a cloze task. Better comprehenders showed smaller N400s for expected words, and larger posterior positivities for unexpected endings, in strongly constraining contexts. These effects correlated with reading comprehension scores. The results suggest that better comprehenders take more advantage of predictions to reduce retrieval costs, and allocate more resources to postlexical integration processes.  相似文献

This study focuses on the shared variance between reading comprehension and word-level reading skills in a population of 534 Greek children in Grades 2 through 4. The correlations between measures of word and pseudoword accuracy and fluency, on the one hand, and vocabulary and comprehension skills, on the other, were sizeable and stable or increasing with grade. However, the unique contribution of word reading to comprehension became negligible after vocabulary measures were entered in hierarchical regression analyses, particularly for higher grades, suggesting that any effects of decoding on comprehension may be mediated by the lexicon, consistent with lexical quality hypothesis. Structural modeling with latent variables revealed an invariant path across grades in which vocabulary was defined by its covariation with reading accuracy and fluency and affected comprehension directly. It is argued that skilled word reading influences comprehension by strengthening lexical representations, at least when phonological decoding can be relatively effortless.  相似文献

We tested the theoretically driven hypotheses that children’s orthographic and semantic learning are associated with their word reading and reading comprehension skills, even when orthographic and semantic knowledge are taken into account. A sample of 139 English-speaking Grade 3 children completed a learning task in which they read stories about new inventions. Then they were tested on their learning of the spelling and meaning of the inventions (i.e., orthographic and semantic learning, respectively). Word reading and reading comprehension were assessed with standardised tasks, and orthographic and semantic knowledge were assessed with choice tasks targeting the spelling and meaning of existing words. The results of our structural equation modeling indicated that orthographic learning predicted word reading directly and reading comprehension indirectly via word reading. We also found that semantic learning predicted reading comprehension directly. These findings support integration of the self-teaching hypothesis and the lexical quality hypothesis.  相似文献

ABSTRACT

Variations in the accuracy and stability of a word’s spelling can be used to gauge the quality of its underlying orthographic representation. The Lexical Quality Hypothesis (LQH) contends that words with higher quality cognitive representations should be accessed more efficiently than those with lower quality representations. If this is the case, deviations in spelling accuracy and stability should be reflected in differences in reading times. Here, 90 teenage participants read 30 words; reading times were recorded. After a 2-week delay, the students spelled these same words 3 times each to gain a measure of orthographic quality. In line with the LQH, faster reading speeds were observed for words with higher spelling accuracy and stability, even for words that were not always spelled perfectly. To our knowledge, our findings provide the first empirical support for the notion that orthographic quality exists along a continuum, both within and across individuals.  相似文献

In this article we consider the difficulties of children who have a specific reading comprehension problem. Our earlier work has shown that good and poor comprehenders differ, in particular, in their ability to make inferences, integrate information in text, understand story structure, and monitor their understanding. We outline some studies that illustrate the poor comprehenders' problems and present two studies that use a comprehension-age match design to explore the direction of causality between comprehension skill and other abilities. We also present data from the first and second stages of a longitudinal study, when the children were 7 to 8 and 8 to 9 years old. Multiple regression analyses show that a number of factors predict significant variance in comprehension skill even after "general ability" factors such as IQ and vocabulary have been taken into account. These findings suggest that, not only can children have comprehension problems in the absence of word recognition problems, but that distinctly different skills predict variance in word recognition and variance in comprehension. The data support the view that single-word reading skills and the ability to build integrated text representations make independent contributions to overall reading ability. We discuss the implications of these findings for our understanding of children's problems in text comprehension, for deaf readers, and for remediation.  相似文献

This study examined whether 10–12‐year‐old children use two reading strategies to aid their text comprehension: (1) distinguishing between important and unimportant words; and (2) resolving anaphoric references. Of interest was the question to what extent use of these reading strategies was predictive of reading comprehension skill over and above decoding skill and vocabulary. Reading strategy use was examined by the recording of eye fixations on specific target words. In contrast to less successful comprehenders, more successful comprehenders invested more processing time in important than in unimportant words. On the other hand, they needed less time to determine the antecedent of an anaphor. The results suggest that more successful comprehenders build a more effective mental model of the text than less successful comprehenders in at least two ways. First, they allocate more attention to the incorporation of goal‐relevant than goal‐irrelevant information into the model. Second, they ascertain that the text model is coherent and richly connected.  相似文献

This study explores the incidence of poor comprehenders, that is, children identified as having reading comprehension difficulties, despite age-appropriate word reading skills. It supports the findings that some children do show poor reading comprehension, despite age-appropriate word reading, as measured with a phonological coding test. However, the proportion of poor comprehenders was smaller than the frequently reported 10–15%, and smaller yet, when average sight word recognition, measured with an orthographic coding test, was also set as a criterion for word reading skill. Compared to average comprehenders, the poor comprehenders’ orthographic coding and daily reading of literary texts were significantly below those of average readers. This study indicates that a lack of reading experience, and likewise, a lack of fluent word reading, may be important factors in understanding 9-year-old poor comprehenders’ difficulties.  相似文献

This paper reports two studies that investigate differences in comprehension monitoring skills between good and poor comprehenders. Two groups of 9– to 10-year-olds, who were matched for reading vocabulary and word recognition skills but who differed in comprehension skill, were selected. In the first study, in which the children were required to find anomalous words and phrases, the skilled comprehenders engaged in more accurate monitoring of sentence level anomalies (but not word level anomalies) than did the poorer comprehenders. In the second study, the comprehension monitoring task required the children to detect pairs of sentences, in short texts, that were contradictory. In addition, the working memory demands of the task were varied by placing the two items of inconsistent information either in adjacent sentences, or in sentences that were separated in the text by several others. As in the first study, less-skilled comprehenders performed more poorly on the detection task, but the difference between the groups was considerably more pronounced when the sentences were separated than when they were adjacent. In addition, the children were given a numerical working memory test, and the poorer comprehenders performed more poorly on this test. However, although working memory performance was related to performance on some of the error detection tasks, comprehension ability was also a good, and sometimes better, predictor. The results are discussed in terms of the different cognitive abilities that might contribute to efficient comprehension monitoring.  相似文献

ABSTRACT

Difficulties suppressing previously encountered but currently irrelevant information from working memory characterize less skilled comprehenders in studies in which they are matched to skilled comprehenders on word decoding and nonverbal IQ. These “extreme” group designs are associated with several methodological issues. When sample size permits, regression approaches permit a more accurate estimation of effects. Using data for students in Grades 6 through 12 (n = 766), regression techniques assessed the significance and size of the relation of suppression to reading comprehension across the distribution of comprehension skill. After accounting for decoding efficiency and nonverbal IQ, suppression, measured by performance on a verbal proactive interference task, accounted for a small amount of significant unique variance in comprehension (less than 1%). A comparison of suppression in less skilled comprehenders matched to more skilled comprehenders (48 per group) on age, word reading efficiency, and nonverbal IQ did not show significant group differences in suppression. The implications of the findings for theories of reading comprehension and for informing comprehension assessment and intervention are discussed.  相似文献

Two studies were conducted across three countries to examine samples of beginning readers without systematic explicit phonics who had reached the same level of word reading accuracy as comparison samples with high and moderate explicit phonics. Had they employed any compensatory learning to reach that level? Four hypotheses of compensatory learning or performance were tested on the samples, all of which represented the lower half of the normative distribution of word reading accuracy. The two samples without explicit phonics received teaching that centered on story text reading and some receptive phonics that arose from this text reading. They did not compensate by relatively greater use of a larger psycholinguistic grain size in the form of rime units. Nor did they compensate by trading off comprehension for text word reading accuracy. In a microtraining study, they showed no compensation in proficiency of initial learning of lexical orthographic representations. For all samples, this initial learning was less effective with spelling than reading training trials. In reading text, the samples without explicit phonics did not compensate by trading off speed for accuracy, or comprehension. On the contrary, they read text faster than the explicit phonics samples. The extra classroom instruction time available to them for text reading, with the consequential extra exposure and practice of word reading, would explain this result.  相似文献

This study examined incremental change for several reading component skills while adolescents were actively learning a word-level intervention and measured pre-/postintervention change in skills. Six ninth graders in two different classes participated during the 2019–2020 academic year. Primary analysis was based on an A-B single-case design across behaviors and participants to observe change in skills proximal to the intervention. Visual analyses of baseline and intervention phase data indicated correlational relationships between the word-level intervention and word identification of multisyllabic words and oral reading fluency. Specifically, an aggregate Tau-U statistical calculation for prosody showed a moderate 0.70 effect size. Secondary analysis indicated a statistically significant group effect for improved strategy knowledge and skill with a 0.90 effect size but no statistically significant group effects for silent reading fluency or sentence comprehension. Discussion includes connections between progress monitoring and reading theory as well as limitations and implications for researchers and practitioners.  相似文献

Although there is evidence for a close link between the development of oral vocabulary and reading comprehension, less clear is whether oral vocabulary skills relate to the development of word-level reading skills. This study investigated vocabulary and literacy in 81 children aged 8 to 10 years. In regression analyses, vocabulary accounted for unique variance in exception word reading and reading comprehension, but not text reading accuracy, decoding, or regular word reading. Consistent with these data, children with poor reading comprehension exhibited oral vocabulary weaknesses and read fewer exception words correctly. These findings demonstrate that oral vocabulary is associated with some, but not all, reading skills. Results are discussed in terms of current models of reading development.  相似文献

Reading comprehension is a multi-dimensional process that includes the reader, the text, and factors associated with the activity of reading. Most research and theories of comprehension are based primarily on research conducted with monolingual English speakers (L1). The present study was designed to investigate the cognitive and linguistic factors that have an influence on reading comprehension in English-as-a-Second-Language (ESL) speakers. The cognitive aspects of reading comprehension among L1 speakers and ESL speakers in the seventh grade were investigated. The performance of both groups was compared and the role of some relevant processes, including word reading, word reading fluency, phonological awareness, working memory, and morphological and syntactic awareness were assessed. Within this sample, three groups were examined: (1) children with poor comprehension (PC) in the absence of word reading difficulties (2) children with poor word reading and poor comprehension (poor readers, PR) (3) and children with both good word reading and comprehension abilities (good comprehenders, GC). The results demonstrated that a variety of cognitive processes, such as working memory and phonological, syntactic, and morphological awareness are important for reading comprehension and compromised in poor comprehenders. The GC group performed better than the PC group on all of the cognitive measures, indicating that comprehension depends on a variety of phonological, memory and linguistic processes and that adequate word recognition skill are important for reading comprehension. The prevalence of the ESL and L1 students was similar across the three reading groups. The ESL and L1 students demonstrated similar performance, indicating that the skills underlying reading comprehension are similar in the ESL and L1 students. This study demonstrated that ESL students are capable of developing word reading and reading comprehension skills that are as strong as those of their L1 peers.  相似文献

The purpose of the study was to determine whether the lexical compounding, suffixation, and part of speech aspects of lexical prosody rendered while reading text aloud are predictive of children’s developing oral reading fluency and reading comprehension skills. Ninety-four third grade children were recorded while reading aloud a grade-level passage targeting lexical prosody contrasts related to suffixation, compounding, and part of speech. Children also completed assessments on reading fluency, word reading efficiency, and reading comprehension skills. Prosodic measurements of pitch and amplitude for each syllable of the targeted words, and spoken head word length in ms for targeted compound words, were carried out. Spectrographic analyses indicated that children generally displayed appropriate prosody for each lexical prosody contrast examined. The extent to which children made these prosodic distinctions between syllables was related to their reading fluency and comprehension skills. The study finds that, in the oral reading of connected texts, children’s use of lexical prosody is an aspect of general reading prosody that is predictive of reading fluency.  相似文献

The current study examined the predictive roles of L2 vocabulary knowledge and L2 word reading skills in explaining individual differences in lexical inferencing in the L2. Participants were 53 Israeli high school students who emigrated from the former Soviet Union, and spoke Russian as an L1 and Hebrew as an L2. L2 vocabulary knowledge and decoding accuracy predicted L2 reading comprehension, which in turn was strongly related to lexical inferencing abilities in the L2. In addition, decoding accuracy predicted additional variance in lexical inferencing, beyond the role of reading comprehension. These findings support the idea that beginning L2 readers with more precise and efficient lexical representations demonstrate better lexical inferencing abilities, most likely due to the increased automatization of word reading, which frees up resources for higher level processing. These results suggest that lexical inferencing from text in the L2 might be limited not only by vocabulary knowledge and higher order comprehension processes, but also by basic decoding skills.  相似文献

ABSTRACT

Reading comprehension is a crucial skill that elementary school students must develop in order to learn science. However, there is not yet enough research about the role that multimodal texts play in scaffolding student reading comprehension of complex scientific processes, such as energy transfer. This study explored how verbal and visual resources (scaffolding level) and individual differences (reading skills) contribute to science reading comprehension. One-hundred and sixty Chilean fifth-graders were assessed on reading skills, vocabulary, and prior science knowledge. A counterbalanced design was used to test two groups: Group 1 reads a text with low multimodal scaffolding and Group 2 reads a text with high multimodal scaffolding. Level of text scaffolding was determined by (1) image function, (2) visual-verbal relations, (3) presence of an explicit explanatory structure, and (4) lexico-grammatical resources. General monomodal and multimodal science reading comprehension were assessed with multiple-choice tests. An ANCOVA analysis revealed non-significant differences between groups after controlling for prior knowledge, fluency, and vocabulary. Likewise, a two-factor ANCOVA analysis showed that the high-multimodal scaffolding text significantly boosted science reading comprehension for low-skilled comprehenders. The paper discusses the implications of these findings for pedagogy and research, aiming to foster multimodal literacy for learning in content areas.  相似文献
