Orthographic processing is a key predictor of reading fluency in good and poor readers in a transparent orthography

Influence of transparency and opacity on the spelling of fricative phonemes

PURPOSE

(1) to verify to what extent the occurrence of possible errors is influenced by the relationship (opaque/transparent) between fricative phonemes and the graphemes with which they can be spelled; (2) verify the differences (if present or not) of relationship types among the phonemes that present common graphemic relationships.

METHODS

We analyzed 750 textual productions from children in the first year of Elementary School (ES), and conducted a survey of the frequency of correct answers and errors in all fricative phonemes of Brazilian Portuguese (BP).

RESULTS

The errors occurred in greater numbers in the group of phonemes with opaque spelling when compared with the number of errors in the group of phonemes with transparent spelling. In the first group, the errors showed a non-symmetrical behavior, since they varied according to the possibilities of graphemes for each phoneme. In the second group, the errors showed a symmetrical behavior.

CONCLUSION

Given the symmetry in the errors of the phonemes of the first group and the non-symmetry of those of the second group, our results point to a gradation in the occurrence of errors, which varies as a function of the transparency and degree of opacity in the relations between phonemes and graphemes of a same class.

Reading Strategies for Children with Developmental Language Disorder

Developmental language disorder (DLD) is considered a neurodevelopmental disorder that compromises language comprehension and/or expression and constitutes a risk factor for learning to read. The aim of the present study was to analyse the reading strategies used by students with DLD to read sentences. There is evidence in the literature that, when linguistic resources are insufficient, the keyword strategy (identifying some of the words in the sentence with their own semantic content, with barely no processing of the function words) is used to read sentences. A total of 31 primary and secondary school students diagnosed with DLD were evaluated using the PEALE battery. The results reveal that students with DLD present heterogeneous profiles that are below the established reading level for their age. In addition, children with DLD and better reading skills use the keyword strategy to read sentences. In conclusion, clinical and educational implications for reading intervention in individuals with DLD are discussed.

Cognitive Requirements of the Phonological Tests Affect Their Ability to Discriminate Children With and Without Developmental Dyslexia

PURPOSE

The main purpose of this study was to investigate whether the performance on each of seven phonological processing (PP) tests from the Russian Test of Phonological Processing (RuToPP), with their varying levels of linguistic complexity and composite phonological indices, are significant predictors of developmental dyslexia (DD) and can reliably differentiate children with and without reading impairment. Additionally, we examined the general contribution of phonological skills to text reading fluency in children with various levels of reading performance.

METHOD

A total of 173 Russian-speaking 7- to 11-year-old children participated in this study: 124 who were typically developing (TD) and 49 who had been diagnosed with DD. We assessed reading fluency with a standardized reading test and PP with the RuToPP. We investigated the potential of phonological skills to predict the presence or absence of a dyslexia diagnosis using multinomial logistic regression, receiver operating characteristic (ROC) curve analysis, and calculations of the sensitivity and specificity of each test and index. The contribution of phonological skills to reading fluency was also assessed in a mixed group of children.

RESULTS

Six of seven RuToPP tests were significant predictors of dyslexia. However, while the RuToPP correctly identified 93%-99% of TD children, for children with dyslexia, it ranged from 4% to 47% depending on the test. In a mixed group of children with and without dyslexia, performance in the more complex phonological tests was a stronger predictor of reading fluency.

CONCLUSIONS

Our findings are consistent with the literature on predictors of literacy skills and dyslexia while uniquely demonstrating the impact of the complexity level of the phonological tests on the classification outcome. PP is a significant and necessary predictor of reading skills, but it is not sufficient for diagnostic purposes.

The Interaction Between Morphological Awareness and Word Detection Skills in Predicting Speeded Passage Reading in Primary and Secondary School Chinese Readers

Previous studies suggest that morphological awareness (MA) and word detection skills have facilitating roles in reading fluency; however, it is unknown whether they can interplay with each other in such roles. The present study explored the relationships of MA, word detection, and passage reading fluency across ages. In total, 180 Chinese primary and secondary school students, aged from 8.52 to 15.67 years, completed tasks for these aforementioned capacities. After controlling gender, non-verbal intelligence, and reading ability at the word level, the results showed that the participants with higher scores for MA or word detection performed better in passage reading fluency. However, the predictive effect of word detection on reading fluency became weaker as the children became older. The interaction between MA and word detection was positive in younger children, whereas this interaction tended to be negative for older children. The results demonstrated a dynamic interplay between MA and word detection in contributing to passage reading fluency in Chinese children. While it has a positive interaction with word detection on reading fluency in younger children, MA may become a compensator in older children (e.g., over 14 years old) whose word detection skills are less effective in facilitating fluent reading.

Enhancing reading skills through a video game mixing action mechanics and cognitive training

In modern societies, training reading skills is fundamental since poor-reading children are at high risk of struggling both at school and in life. Reading relies not only on oral language abilities but also on several executive functions. Considering their importance for literacy, training executive functions-particularly, attentional control has been suggested as a promising way of improving reading skills. For this reason, we developed a video game-based cognitive intervention aimed at improving several facets of executive functions. This game is composed of mini-games that apply gamified versions of standard clinical exercises linked through a game environment with action video game dynamics. Here, in a study involving 151 typically reading children, we demonstrated that after this general-domain behavioural intervention reading abilities, as well as attentional and planning skills, were significantly improved. Our results showed that training attentional control can translate into better reading efficiency, maintained at a follow-up test 6 months later.

Differences and Similarities in the Contributions of Phonological Awareness, Orthographic Knowledge and Semantic Competence to Reading Fluency in Chinese School-Age Children With and Without Hearing Loss

Compared with the large number of studies on reading of children with hearing loss (HL) in alphabetic languages, there are only a very limited number of studies on reading of Chinese-speaking children with HL. It remains unclear how phonological, orthographic, and semantic skills contribute to reading fluency of Chinese school-age children with HL. The present study explored this issue by examining the performances of children with HL on reading fluency and three linguistic skills compared with matched controls with normal hearing (NH). Specifically, twenty-eight children with HL and 28 chronological-age-matched children with NH were tested on word/sentence reading fluency (WRF/SRF), phonological awareness (PA) which was composed of onset/vowel/lexical tone awareness, orthographic knowledge (OK), and semantic competence (SC) which comprised animal word identification, pseudo-homophone detection, and word segmentation. Results showed that children with HL lagged behind their peers with NH in WRF/SRF and most of the phonological, orthographic, and semantic subskills except onset awareness and pseudo-homophone detection. Furthermore, the significant contributors to WRF differed between the two groups with PA being the significant contributor in the children with NH while OK being the significant contributor in the children with HL. However, the significant contributor to SRF did not differ between the two groups with SC being the only significant contributor. These results revealed not only between-group differences but also similarities in the relative contributions of PA, OK, and SC to reading fluency at both word and sentence levels, which has practical implications for developing better training programs to improve reading for children with HL.

How does rapid automatized naming influence orthographic knowledge?

Rapid automatized naming (RAN) is a strong predictor of reading fluency across languages, and some researchers have attributed this to the contribution of RAN to the development of orthographic knowledge, which is predictive of reading fluency. However, to date, it remains unclear whether RAN (alphanumeric and nonalphanumeric) predicts orthographic knowledge (OK) and what skills may mediate their relation. To examine the RAN-OK relations, we assessed 114 Grade 3 Spanish-speaking Mexican children (58 girls; M_age = 7.9 years, SD = 0.3) on RAN (objects and digits), orthographic knowledge (lexical and sublexical; accuracy and response time), speed of processing, multi-element processing, phonemic awareness, and reading fluency. Path analyses showed first that, OK (both lexical and sublexical) partly mediated the effects of RAN on reading fluency. Second, multiple mediation analyses showed an indirect effect of both RAN tasks on lexical and sublexical OK through phonological awareness. In view of Ehri's amalgamation hypothesis and Share's self-teaching hypothesis, our findings suggest that RAN may reflect, in part, the speed with which the phonological representations of letters are accessed and retrieved, which subsequently influences how quickly orthographic representations can be formed and accessed.

An evaluation of systematized phonics on reading proficiency in Swedish second grade poor readers: Effects on pseudoword and sight word reading skills

The aim of the present study was to evaluate the effect of systematized phonics on word reading in Swedish second grade poor readers. Forty-nine children who performed at or below the 25th percentile on pseudoword reading and/or sight word reading at the beginning of second grade participated in the study. The study had a cross-over design exploring within-and between-group effects of two different conditions: systematized phonics and classroom instruction. Overall, systematized phonics proved more effective than classroom instruction. At pre-intervention, no child performed above the 30th percentile in pseudoword reading or sight word reading. At post-intervention, corresponding numbers were 69% for pseudoword reading and 35% for sight word reading. Implications for a policy change in Sweden towards mandatory systematized phonics in primary school are discussed.

Cognitive Correlates of Reading Fluency in Chinese School-Aged Children

Previous studies have showed that reading fluency is strongly associated with cognitive skills, including rapid automatized naming, phonological awareness, orthographical awareness, and so on. However, these studies are largely based on alphabetic languages, and it remains unclear which cognitive factors contribute to the development of reading fluency in logographic Chinese, a language in which the graphic forms map onto morphemes (meaning) rather than phonemes. In Study 1, we tested 179 Chinese children aged 6 to 9 on a set of cognitive tasks as well as for word reading accuracy and sentence reading fluency. The results showed that rapid naming, writing fluency, and phonological awareness significantly predicted reading fluency in both beginning and intermediate readers. In addition, while the contribution of rapid naming and writing fluency increased with grades, the effect of phonological awareness decreased. In Study 2, we examined the role of visual crowding in reading fluency in a subgroup of 86 children and found that visual crowding accounted for the unique variance of individual differences in reading fluency. The findings reflect both universal and language-specific cognitive correlates of reading fluency and provide important implications for potentially effective treatment for individuals suffering from Chinese reading disabilities, particularly in terms of reading fluency.
