A Reading-Level Design Study of Phonological Skills Underlying Fourth-Grade Children''s Word Reading Difficulties

A 3-group reading-level design was used to investigate phonological analysis, verbal working memory, and pseudoword reading performance in less skilled fourth-grade readers. Children were given phonological oddity tasks assessing their sensitivity to subsyllabic and phonemic units, together with standardized tests of verbal working memory and pseudoword reading. Less skilled fourth-grade readers performed lower than both chronological age and reading-level controls on the phonological oddity and pseudoword reading tests. Less skilled fourth-grade readers performed at the same level as skilled second-grade readers on a test of verbal working memory. Skilled fourth-grade readers scored higher than both other groups on this test. Correlational analyses were consistent with the view that phonological analysis skills contribute more strongly than verbal working memory skills to children's decoding abilities.     

The Relationship of Spelling Recognition, RAN, and Phonological Awareness to Reading Skills in Older Poor Readers and Younger Reading-Matched Controls

The role of spelling recognition was examined in word reading skills and reading comprehension for dyslexic and nondyslexic children. Dyslexic and nondyslexic children were matched on their raw word reading proficiency. Relationships between spelling recognition and the following were examined for both groups of children: verbal ability, working memory, phonological measures, rapid naming, word reading, and reading comprehension. Children’s performance in spelling recognition was significantly associated with their skills in word reading and reading comprehension regardless of their reading disability status. Furthermore, spelling recognition contributed significant variance to reading comprehension for both dyslexic and nondyslexic children after the effects of phonological awareness, rapid naming, and word reading proficiency had been accounted for. The results support the role of spelling recognition in reading development for both groups of children and they are discussed using a componential reading fluency framework.     

Teaching Phonological Awareness and Metacognitive Strategies to Children with Reading Difficulties: A comparison of two instructional methods

This paper describes an applied training study which investigated the differential effects of two instructional methods on the reading performance of primary school children with reading difficulties. Sixty five children aged 7-10 participated. Twenty five children were assigned to each of two experimental groups: direct instruction in phonological awareness and the alphabetic principle, or the same direct instruction in phonological awareness in conjunction with training in specific metalinguistic concepts and metacognitive strategies. Fifteen children were selected as controls. Reading performance from baseline was measured within a pretest, posttest, and delayed posttest experimental design. Data and results are presented on 60 children owing to attrition. Results showed that direct instruction in phonological awareness improved the reading performance of children with reading difficulties over time. However, direct instruction in phonological awareness in conjunction with explicit training in specific metalinguistic concepts and metacognitive strategies was more advantageous overall.     

Ameliorating Early Reading Failure by Integrating the Teaching of Reading and Phonological Skills: The Phonological Linkage Hypothesis

We present a longitudinal intervention study of children experiencing difficulties in the early stages of learning to read. Our subjects, 7-year-old poor readers, were divided into 4 matched groups and assigned to 1 of 3 experimental teaching conditions: Reading with Phonology, Reading Alone, Phonology Alone, and a Control. Although the Phonology Alone group showed most improvement on phonological tasks, the Reading with Phonology group made most progress in reading. These results show that interventions to boost phonological skills need to be integrated with the teaching of reading if they are to be maximally effective in improving literacy skills.     

Augmenting the Simple View of Reading for Struggling Adult Readers: A Unique Role for Background Knowledge

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.     

Phonological Awareness and Rapid Naming Skills of Children with Reading Disabilities and Children with Reading Disabilities Who Are At Risk for Mathematics Difficulties

Limited research has examined the skills of children with a reading disability (RD) and children with RD and a mathematics disability (MD). Even less research has examined the phonological awareness (PA) and rapid automatized naming (RAN) skills in these two groups of children and how these skills relate to reading and math achievement. Additionally, various classification criteria are frequently implemented to classify children with MD. The purpose of this study, therefore, was to examine the PA and RAN skills in children who met different criteria for RD only and children with RD who are at risk for mathematics difficulties (MDR). Participants were 114 second‐ or third‐grade students with RD from public elementary schools in three large metropolitan areas. Students were classified as at risk for mathematics difficulties utilizing a 25th‐percentile cutoff and a 15th‐percentile cutoff as assessed by the KeyMath‐Revised Test ( Connolly, 1988 ). A series of PA and RAN measures were administered along with a range of reading and mathematics measures. Hierarchical regression analyses indicated that children with RD only evidenced a different pattern of results compared to children with RD + MDR. Additionally, using a more stringent criterion to classify children at risk for mathematics difficulties resulted in a differential pattern of results when compared to a less stringent classification criterion.     

Phonological and Surface Profiles of Reading Difficulties Among Very Low Birth Weight Children: Converging Evidence for the Developmental Lag Hypothesis

The purpose of this study was to test the developmental lag hypothesis, which assumes that a surface pattern of reading difficulties should be attributed to a general developmental delay rather than to specific deficits in the acquisition of orthographic decoding skills. We compared a sample of very low birth weight children (less than 1,500 g), known to be at higher risk of a general developmental delay, with a group of same-age, normal readers. Following the same regression-based procedures seen in the work of Castles and Coltheart (1993); Manis, Seidenberg, Doi, McBride-Chang, and Petersen (1996); and Stanovich, Siegel, and Gottardo (1997), we found that only 1 very low birth weight child could be classified as phonologically dyslexic, whereas 12 out of 60 very low birth weight children were identified as surface dyslexic. This subgroup of children with surface dyslexia was impaired not only in all reading measures employed in this study, but also in several behavioral domains associated with a developmental lag.     

Phonological Awareness in Literacy Acquisition: It's Not Only for Children

The aim of this study was to determine the cognitive processes of adult literacy acquisition. We assessed the progress of 59 women participating in an intensive adult literacy program that we have developed in Turkey. After only 90 hr of instruction, there were significant improvements in letter and word recognition, phonological awareness, and spelling levels. Word recognition and spelling were predicted by phonological awareness. The results were consistent with studies on children's literacy acquisition, which show the critical nature of phonological awareness in literacy acquisition.     

Phonological Processing and Word Reading in Typically Developing and Reading Disabled Children: Severity Matters

In this study word reading (WR) fluency was used to dichotomously classify 1,598 Dutch children at different cutoffs, indicating (very) poor or (very) good reading performance. Analysis of variance and receiver operating characteristics were used to investigate the effects of rapid automatized naming (RAN) and phonemic awareness (PA) in predicting group membership. The highest predictive values were found for the combination of RAN and PA, particularly for the poorest readers. Furthermore, results indicate that with the severity of impairment, WR is more dominated by deficient PA, which is interpreted as an enduring problem with sublexical processing. Another main result is that with the increase of reading skill, the contribution of PA diminishes, whereas the contribution of RAN remains fairly constant for the whole reading fluency continuum. These results warrant the conclusion that whereas PA hallmarks reading disability, RAN appears to be the default predictor for above-average or excellent reading proficiency.     

A Cognitive View of Reading Comprehension: Implications for Reading Difficulties

Our aim in the present paper is to discuss a “cognitive view” of reading comprehension, with particular attention to research findings that have the potential to improve our understanding of difficulties in reading comprehension. We provide an overview of how specific sources of difficulties in inference making, executive functions, and attention allocation influence reading comprehension processes and outcomes and may lead to reading comprehension problems. Finally, we discuss how the consideration of these potential sources of difficulty have practical implications for the design and selection of instructional materials.     

Use of Contextual Information and Prediction by Struggling Adult Readers: Evidence From Reading Times and Event-Related Potentials

We employed self-paced reading and event-related potential measures to investigate how adults of varying literacy levels use sentence context information when reading. Community-dwelling participants read strongly and weakly constraining sentences that ended with expected or unexpected target words. Skilled readers showed N400s that were graded by the cloze probability of the targets, with larger N400s for more unexpected words. Moreover, it took these participants longer to read unexpected targets in strongly than weakly constraining sentences, suggesting a processing cost for revising predictions. Among less skilled readers, a reliable N400 difference was found between expected and unexpected targets only for the strongly constraining sentences. They also took longer when targets were unexpected, regardless of the context. These findings suggest that lower literacy readers could only immediately take advantage of strongly constraining context information to facilitate word processing and that they do not make as much use of predictive processing during comprehension.     

Exploring the Role of Bases and Suffixes When Reading Familiar and Unfamiliar Words: Evidence From French Young Readers

We examined whether French third- and fifth-grade children rely on morphemes when recognizing words and whether this reliance depends on word familiarity. We manipulated the presence of bases and suffixes in words and pseudowords to compare their contribution in a lexical decision task. Both bases and suffixes facilitated word reading accuracy and speed across all grades, even though the co-occurrence of a base and a suffix reduced the benefit associated to the presence of morphemes in third-grade children. Speed of pseudoword (i.e., unfamiliar word) reading was also influenced by base and suffix, and the combination of these units leaded to a high rate of false alarms. These results bring new evidence of morphological analysis in the reading of French familiar and unfamiliar words.     

Relations Among Oral Reading Fluency,Silent Reading Fluency,and Reading Comprehension: A Latent Variable Study of First-Grade Readers

In the present study, we examined oral and silent reading fluency and their relations with reading comprehension. In a series of structural equation models with latent variables using data from 316 first-grade students, (a) silent and oral reading fluency were found to be related yet distinct forms of reading fluency, (b) silent reading fluency predicted reading comprehension better for skilled readers than for average readers, (c) list reading fluency predicted reading comprehension better for average readers than for skilled readers, and (d) listening comprehension predicted reading comprehension better for skilled readers than for average readers.     

Auditory Sensory Processing and Phonological Development in High IQ and Exceptional Readers,Typically Developing Readers,and Children With Dyslexia: A Longitudinal Study

Phonological difficulties characterize children with developmental dyslexia across languages, but whether impaired auditory processing underlies these phonological difficulties is debated. Here the causal question is addressed by exploring whether individual differences in sensory processing predict the development of phonological awareness in 86 English-speaking lower- and middle-class children aged 8 years in 2005 who had dyslexia, or were age-matched typically developing children, some with exceptional reading/high IQ. The predictive relations between auditory processing and phonological development are robust for this sample even when phonological awareness at Time 1 (the autoregressor) is controlled. High reading/IQ does not much impact these relations. The data suggest that basic sensory abilities are significant longitudinal predictors of growth in phonological awareness in children.     

Models of Speech Perception and Phonological Processing in Reading

Multiple measures of speech perception, phonological awareness, naming speed, verbal short-term memory, and word reading were concurrently administered to 136 third- and fourth-grade children. Structural equation modeling was used to contrast 5 models of the relations of speech perception and phonological processing skills to reading with IQ controlled. The best-fitting model, the Indirect Model, was one in which the effect of speech perception on reading was mediated by its relations with phonological processing abilities. Naming speed was particularly highly associated with speech perception, possible evidence for the Motor Theory. Phonological awareness was also substantially correlated with speech perception.     

Phonological sensitivity in severely and profoundly deaf readers of French

In order to become expert readers of an alphabetical language like French, students must develop and adequately use phonological knowledge. Considering that the phonological knowledge used in reading largely comes from knowledge of the oral language, what happens when the oral language is not accessible, as is the case for many deaf children? In this study, graphophonemic and syllabic processes in pseudoword reading were assessed with a similarity judgment task. Gestual deaf subjects aged 10–18 years old (N = 24) were compared to 24 age-matched hearing subjects. The results show that deaf readers are less sensitive to the graphemic and the syllabic structures of pseudo-words than hearing readers. In deaf subjects, the results are different than chance-level in the 13–15 and the 16–18-year-old groups. These results indicate that gestual deaf readers can develop phonological knowledge even in settings where sign language is promoted.     

聋人书面语学习困难的研究

为了了解聋人学习书面语的困难,研究使用资料检索和语料分析的方法,通过对手语和汉语书面语材料的对应研究,对“母语”、“第二语言”和“外语”概念的研究,对“过渡语”、“洋泾浜”和“克里奥尔语”概念的分析,发现手语和书面语在语言的载体、词汇语法、思维方式上存在着诸多的差异;聋人书面语的学习在语言环境、语言输入、语言迁移上存在比第二语言学习者更多的困难;聋人在书面语学习中出现的偏误是第二语言学习中的普遍现象,是一种有积极意义的过渡语;结论是要宽待聋人学习书面语中出现的偏误,要加强从语法的角度对手语和汉语书面语差异的研究。     

Phonological Analysis Skills, Verbal Working Memory, and Reading Ability in Second-Grade Children

This study tested the hypothesis that phonological analysis skills make a unique contribution to reading ability against the hypothesis that one latent phonological factor underlies the assocations among analysis skills, verbal working memory skills, and reading achievement. Hierachical multiple regression analyses examined the unique contributions of phonological analysis and verbal working memory measures to the prediction of 3 measures of concurrent reading ability in 68 second-grade children (mean age 7 years 4 months). Phonological analysis and verbal working memory measures each accounted for unique variation in each of the 3 reading measures. In addition, phonological analysis measures, but not verbal working memory measures, were particularly strong predictors of pseudoword reading skills. These results suggest that, although phonological analysis and verbal working memory skills share a substantial amount of common variance, phonological analysis and verbal working memory tasks do tap somewhat different reading-related skills.     

语音编码在不同水平ESL学习者默读过程中的表现

感知综合校对测试主要运用于检测学习者默读文本中的语音编码.通过对英语作为第二语言的成年学习者进行测验发现,无论这些词是同音异义还是非同音异义,学习者在无错误的文本中都能够分辨词语的连续性,这表明在词汇处理过程中,同音异义词效应反映了语音编码的激活,但不同水平的学习者中语音编码激活程度并不相同.
