Predictors of reading delay in deaf adolescents: the relative contributions of rapid automatized naming speed and phonological awareness and decoding

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.     

Deconstructing rapid automatized naming: Component processes and the prediction of reading difficulties

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.     

The role of speed of processing, rapid naming, and phonological awareness in reading achievement

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.     

Implicit phonological awareness and early reading development in prelingually deaf children

This article reports on a longitudinal study of reading progress in a group of five-year-old deaf children and a group of hearing controls. All children were prereaders at the beginning of the study and the IQ of the two groups were matched. The deaf children varied considerably on a number of measures, including implicit phonological awareness, oral ability, and familiarity with British Sign Language and fingerspelling. Overall, the deaf children made significantly less reading progress than their hearing peers over the first year of schooling, and they also scored significantly lower on the test of rime and onset awareness. However, considerable variation in the reading progress of the deaf children was positively correlated with oral skills, rime/onset awareness, and language comprehension. Language comprehension, itself, was positively correlated with signing and fingerspelling. The deaf children were assessed again one year later, when learning to read continued to be very delayed, and the pattern of correlation was essentially the same. The implications of these findings for the education of deaf children are discussed.     

History and significance of rapid automatized naming

In this review, the origins and history of a test of rapid automatized naming (RAN) are traced from nineteenth-century classical brain-behavior analyses of cases of acquired “alexia without agraphia” through adaptations to studies of normal and reading disabled children. The element of speed (of responding verbally to a visual stimulus) was derived from a test of color naming developed over 50 years ago as a bedside measure of recovery from brain injuries. Merging the “visual-verbal” connection essential to reading (specific) with the response time element (general), RAN turned out to be a useful correlate and predictor of reading competence, accounting even for variance beyond that accounted for by timed tests of discrete naming. As one of the two deficits highlighted in the Double Deficit hypothesis with phonological awareness, RAN has emerged as something more than a particularly difficult challenge to a unitary phonological retrieval deficit, and has itself been subjected to further dissection. Coming full circle to its origins, recent research suggests that RAN taps both visual-verbal (language domain) and processing speed (executive domain) contributions to reading.     

Comparing the contribution of two tests of working memory to reading in relation to phonological awareness and rapid naming speed

The purpose of this study was to compare the contribution of two different versions of working memory to word reading and reading comprehension in relation to phonological awareness and rapid naming speed. Fifty children were administered two measures of working memory, namely an adaptation of the Daneman and Carpenter sentence span task and Sentence Question, tests of phonological awareness, rapid naming speed, word reading and reading comprehension. The results indicated that Sentence Question accounted for unique variance over and beyond the effects of Daneman and Carpenter's sentence span task, whereas the latter did not when the effects of Sentence Question were partialled out. In addition, both phonological awareness and rapid naming were accounting for unique variance beyond the effects of working memory in predicting reading. The role of working memory on reading is discussed, and future directions for research are suggested.     

The relationship of phonological awareness, rapid naming, and verbal memory to severe reading and spelling disability.

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.     

The relations of early phonological awareness,rapid‐naming and speed of processing with the development of spelling and reading: a longitudinal examination

Phonological awareness has been found to be strongly related to spelling. Findings on the relations between rapid‐naming and spelling are less consistent and have been suggested to be shared with speed of processing. This study set out to examine these relations in spelling and reading of Hebrew. Children attending the regular educational system were followed longitudinally (N = 70): phonological awareness, rapid‐naming and speed of processing were tested in kindergarten and in grade 1, and spelling and reading were tested in grade 2. Kindergarten and grade 1 rapid‐naming predicted spelling and word reading, and grade 1 phonological awareness predicted spelling, word reading and decoding. Speed of processing was an insignificant predictor. The findings extend the role of phonological awareness in spelling to an orthography with partial phonological representations and concurrently suggest weak relations. The results further suggest a link between rapid‐naming and orthographic knowledge, which may not be explained by shared variance with speed of processing.     

Development of phonological awareness and reading acquisition

The work is aimed at studying the relations between different levels of phonological awareness and early reading ability. Ten different metaphonological tasks as well as a reading (syllables and word decoding) test were administered to kindergarteners and first graders. The correlations between metaphonological abilities and reading were highly significant for the kindergarteners. In the tasks involving sensitivity to phonological similarities, correlations were weak and nonsignificant for the first graders. A principal components analysis shows two components at first grade: sensitivity to phonological similarities and segmental awareness. Reading was related only to the latter. The differential performance between prereaders and readers within the group of kindergarten shows that sensitivity to phonological similarities and initial isolation of segments takes precedence over alphabetic reading. Segmental awareness, however, does not develop outside the learning of the alphabetical code as the evidence provided by results in deleting, counting and reversal tasks suggests. All children who had developed segmental awareness were able to read but, interestingly enough, some good readers performed poorly in some of the segmental awareness tasks (i.e. deleting of initial phoneme).     

Sensitivity to linguistic stress,phonological awareness and early reading ability in preschoolers

Recent research has found that sensitivity to linguistic stress is related to phonological awareness and reading development. This study investigated the roles of two types of linguistic stress sensitivity (lexical and metrical stress) in the phonological awareness and reading development of young children. Forty‐five kindergarten children were tested on a battery of tasks that examined linguistic stress sensitivity and early reading ability. Results indicated that lexical stress, but not metrical stress sensitivity, is significantly related to phonological awareness and early reading ability. However, lexical stress is not able to predict unique variance in early reading ability once phonological awareness is controlled for. The relationships of both lexical and metrical stress sensitivity with phonological awareness and early reading development are discussed.     

Predicting reading ability over the long term: The changing roles of letter naming,phonological awareness and orthographic processing

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.     

Rapid automatized naming,word-level reading,and oral reading fluency in first-grade Korean readers at risk for reading difficulties

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.     

A clinical rationale for assessing rapid automatized naming in children with language disorders

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.     

Distinctive patterns of relationship of phonological awareness and working memory with reading development

The purpose of this study was to assess the contributions of specific components of verbal and nonverbal working memory and of phonological awareness to the prediction of reading achievement. One hundred and three children from grades 1, 2, and 3 were administered a measure of phonological awareness, four measures of working memory, four measures of academic achievement, and a measure of verbal intelligence. Separate multiple regression analyses controlling for the effects of age, sex and verbal intelligence showed that tests of verbal memory and of direct recall significantly predicted reading and spelling achievement whereas tests of backward recall significantly predicted only pseudoword identification. Phonological awareness was also found to relate significantly to reading and spelling achievement even when working memory was partialled out. Thus, phonological awareness and measures of working memory predicted specific and significant amounts of variance in reading and spelling achievement. Further, none of these measures were specifically related to arithmetic achievement. The specific roles of phonological awareness and working memory in reading development are examined in the discussion.     

Naming speed deficits in adults with reading disabilities: a test of the double-deficit hypothesis

The present study investigated the persistent nature of naming speed deficits within the context of the double-deficit hypothesis in a university sample of adults with reading disabilities (RD). Twenty-five university students with RD were compared to 28 typically achieving readers on measures of reading skill, phonological processing, and naming speed. The results indicated that both naming speed and phonological processing deficits characterized the RD group. In a regression analysis, neither naming speed nor phonological processing were important variables in explaining comprehension when reading rate was in the model. The results of the present study are mixed at best and are consistent with earlier conclusions that support for the double-deficit hypothesis of dyslexia remains limited.     

The effects of morphological versus phonological awareness training in kindergarten on reading development

The aim of this study was toinvestigate the long-term effects of twodifferent training programs in kindergarten onreading development. One group received aprogram focusing on the phonological structureof words, while a second group received aprogram focusing on morphology. Both groupsalso had some print exposure focusing onphonological or morphological elementsrespectively. During their last pre-schoolyear, participants received training for 30minutes per week for a total of 17 weeks. Acontrol group received no intervention but wasregularly visited by the researcher and hadextensive print exposure. Both trained groupsshowed improvements in phonological,morphological and reading skills in comparisonto the Control Group. The effects of trainingvaried according to mother's educational level:Children of relatively highly educated mothersentered the pre-school training with betterdeveloped metalinguistic abilities thanchildren of less well educated mothers.Significant interactions between the groups andthe mother's educational level, for some of theschool reading measures, indicated thatdifferent training programs had differenteffects on different groups of children.Children of poorly educated mothers profitedthe most from metaphonological training whilechildren of highly educated mothers profitedthe most from metamorphological training.

The role of different levels of phonological awareness in the development of reading and spelling in Greek

Phonological awareness is a strong predictor of children's progress in literacy acquisition. There are different ways of segmenting words into sound sequences – syllables, phonemes, onset-rime – and little is known about whether these different levels of segmentation vary in their contribution to reading and writing. Does one of them – for example, phoneme awareness – play the major role in learning to read and spell making the other phonological units irrelevant to the prediction of reading? Or do different levels of analysis make independent contributions to reading and spelling?

Our study investigated whether syllable and phoneme awareness make independent contributions to reading and spelling in Greek. Four measures were used: syllable awareness, phoneme awareness, reading and spelling. Analyses of variance showed that Greek speaking children found it easier to analyse words into syllables than phonemes, irrespective of the influence of task variables such as position of the phonological element, word length, and placement of stress in the word. Regression analyses showed that syllable and phoneme awareness make significant and independent contributions to learning written Greek. We conclude that phonological awareness is a multidimensional phenomenon and that the different dimensions contribute to reading and writing in Greek.

     

Exploring mechanisms of rapid automatized naming to arithmetic skills in Chinese primary schoolers

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.
