Exploring the Korean Hangul Word Decoding Properties of Children with Reading Disabilities: Implication for Reading Intervention and Reading Related Language Factors

Objectives: This study analyzed the Korean Hangul word decoding properties of children with reading disabilities by considering reading intervention and reading related language factors.Methods: A corresponding sample t-test, correlation analysis, and repeated measurement were examined for the relevance of Hangul and reading difficulties, predictors of Hangul reading difficulties, and the effects of Korean word meaningfulness (word/non-word) and spelling regularity (regular/irregular) variables.Results: 1) After reading intervention, children with reading disabilities improved in their Hangul decoding, listening comprehension, phonological awareness, and word writing scores. 2) Before and after reading interventions, variables related to decoding were receptive vocabulary, phonological awareness, word writing, and rapid naming. 3) The variables of children’s ability that predicted decoding were word writing, listening comprehension, receptive vocabulary, and rapid naming; and the variable that predicted non-word decoding was word writing. Phonological awareness, which showed significant correlation with decoding scores, did not act as a significant predictor of decoding scores. 4) Reading interventions and decoding-level variables (word meaning and spelling regularity) both showed significant effects in the decoding of Korean Hangul, especially after reading interventions.Conclusion: The reading disability of Hangul is acting on both the characteristics of the ideogram and phonogram system, and the characteristics of Hangul’s unique spelling system.

General Visual Ability as a Moderator in the Relationship RAN –Fluency in a Regular Orthography

Visual skills play a controversial role in the literacy process. The predictive part of RAN on fluency is known, especially in transparent spelling. In this research, we wanted to explore the influence of visual abilities on literacy for primary school students; for this purpose, we evaluated 209 students. We tested both the Reading and decoding efficiency, rapid naming, and visual abilities. The interaction of rapid naming (RAN) and visual ability (VA) significantly determined fluency. This association is discussed concerning other findings that have demonstrated the visuospatial abilities influence literacy.

Action video game training improves text reading accuracy, rate and comprehension in children with dyslexia: a randomized controlled trial

Dynamic visual attention training using Action Video Games (AVGs) is a promising intervention for dyslexia. This study investigated the efficacy of 5 h (10 × 30 min) of AVG training in dyslexic children (aged 8–13) using ‘Fruit Ninja’, while exploring whether increasing attentional and eye movement demands enhanced AVG effectiveness. Regular (AVG-R; n = 22) and enhanced AVG training (AVG+; n = 23) were compared to a treatment-as-usual comparison group (n = 19) on reading, rapid naming, eye movements and visuo-temporal processing. Playing ‘Fruit Ninja’ for only 5 h significantly improved reading accuracy, rate, comprehension and rapid naming of both AVG groups, compared to the comparison group, though increasing attentional demands did not enhance AVG efficacy. Participants whose low contrast magnocellular-temporal processing improved most following training also showed significantly greater improvement in reading accuracy. The findings demonstrate a clear role for visual attention in reading and highlight the clinical applicability of AVGs as a fun, motivational and engaging intervention for dyslexia.

Examining the growth trajectories and cognitive predictors of reading in a consistent orthography: Evidence from a 10-year longitudinal study

We examined the growth trajectories of reading in a consistent orthography (Greek) in two developmental periods (from Grade 1 to Grade 4 and from Grade 4 to Grade 10) and what cognitive skills predict the growth patterns. Seventy-five Greek-speaking children were assessed in Grades 1, 2, 4, 6, and 10 on word-, nonword-, and text-reading fluency. In Grades 1 and 4, they were also assessed on phonological awareness, rapid naming, phonological memory, orthographic knowledge, and articulation rate. Results of growth curve modeling showed that during the first developmental period, there was a rapid initial growth from Grade 1 to Grade 2 followed by a less rapid growth from Grade 2 to Grade 4. In the second developmental period, the slow growth continued. In both developmental periods, rapid naming and orthographic knowledge predicted the initial status of all reading outcomes and phonological memory predicted the initial status of nonword-reading fluency. Phonological awareness predicted the initial status of nonword-reading fluency in the first developmental period and the initial status of word- and text-reading fluency in the second developmental period. None of the cognitive skills predicted the growth rate in reading skills. Theoretical and practical implications of these findings are discussed.

To Name or Not to Name: Eye Movements and Semantic Processing in RAN and Reading

This study examined the well-established relationship between rapid naming and reading. Rapid automatized naming (RAN) has long been demonstrated as a strong predictor of reading abilities. Despite extensive research spanning over 4 decades, the underlying mechanisms of these causes remain a subject of inquiry. The current study investigated the role of eye movements and semantic processing in defining the RAN-reading relationship. The participants in this study were 42 English-speaking undergraduate students at a British university. The materials included a word reading task, two conventional RAN tasks (object and digit), and two RAN-like categorization tasks (object and digit). The results obtained suggested the interdependence between rapid naming and semantic processing. Hierarchical multiple regression analyses revealed that oculomotor control remains an integral part of variability in RAN and reading performance. Taken together, our results suggest that RAN and reading measures are correlated because both require rapid and accurate retrieval of phonological representations, semantic properties of visual stimuli, and stable co-ordination of eye movements.

Basic reading and reading-related language skills in adults with deficient reading comprehension who read a transparent orthography

This study set out to examine the basic reading skills (accuracy and fluency in decoding, word and text reading) and some of the reading-related language skills (phonological awareness and rapid-naming) of 54 adults with low reading comprehension, who read the transparent German orthography. Participants were born in Germany and showed a typical non-verbal processing speed. With the exception of reading accuracy, participants were expected to present deficits in all basic reading and reading-related skills. The average performance in measures of decoding and word reading fluency was extremely low. A notable proportion of the sample, however, did not present a deficit in these measures. As expected, the average rate of reading errors was generally low. Nevertheless, text reading accuracy was deficient for one quarter of the sample. Tests addressing the reading-related language skills also indicated an average low performance in phonological awareness, but not in rapid-naming. Here too, a notable variance was observed. These results suggest that deficits in the basic reading skills and in phonological awareness characterise, on average, adults with low reading comprehension. At the same time, significant deficits in reading comprehension in this population do not necessarily imply deficits in the more basic skills of reading as well. In addition, the results indicate that reading accuracy constitutes a source of difficulty for some of these adults, despite the reading of a transparent orthography. The sources for the variance in performance throughout the different reading and reading-related measures remain to be explored.
