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.

Comparison of temporal fine structure sensitivity and concurrent vowel perception between children with and without reading disability

Background: Children with reading disabilities (RD) exhibit difficulty in perceiving speech in background noise due to poor auditory stream segregation. There is a dearth of literature on measures of temporal fine structure sensitivity (TFS) and concurrent vowel perception abilities to assess auditory stream segregation in children with reading disabilities. Hence the present study compared temporal fine structure sensitivity (TFS) and concurrent vowel perception abilities between children with and without reading deficits. Method: The present research consisted of a total number of 30 participants, 15 children with reading disabilities (RD) and fifteen typically developing (TD) children within the age range of 7-14 years and were designated as Group 1 and Group 2 respectively. Both groups were matched for age, grade, and classroom curricular instructions. The groups were evaluated for TFS and concurrent vowel perception abilities and the performance was compared using independent ‘t’ test and repeated measure ANOVA respectively. Results: Results revealed that the children with RD performed significantly (p < 0.001) poorer than TD children on both TFS and concurrent vowel identification task. On concurrent vowel identification tasks, there was no significant interaction found between reading ability and F0 difference suggesting that the trend was similar in both the groups. Conclusion: The study concludes that the children with RD show poor temporal fine structure sensitivity and concurrent vowel identification scores compared to age and grade matched TD children owing to poor auditory stream segregation in children with RD.

Inclusive learning strategies to enhance reading skill among the students with reading disability: An Occupation and Participation Approach to Reading Intervention (OPARI) in the rural Indian classroom

Reading is a challenging task for reading disability for which they need comprehensive strategies like sensory and neurocognitive requirements. With this notion, the article aims to find, the appropriate pedagogies and clinical practices used for intervening the reading disability in Indian public schools. To examine, qualitative interviews were conducted with ten high school teachers and four special education teachers, who work in Government schools in India especially in the state of Tamil Nadu. The interview focused the opinions of the teachers on reading disability, facilities and pedagogies provided to the reading disability and from the interview, the study has derived the results in three main themes as, teachers’ views on reading disabilities, inadequate teaching strategies for reading disabilities, special education to the reading disabilities. In the discussion section, the article attempts to resolve the issues raised in the interview by introducing an exclusive approach to intervene reading disability. The article incorporates the principles of the Occupational Participation and Adaptation to Reading Intervention approach (OPARI) to intervene the reading disability and attempts to find a solution to the issues. In addition, the article attempts to justify the neuroscience behind the OPARI by highlighting the dopamine activation in the brain while adapting to reading. In the conclusion section, the article emphasizes therapeutic associative teaching and the need to implement OPARI in Indian classrooms.

Effects of Varying Levels of Data Use to Intensify a Multisyllabic Word Reading Intervention for Upper Elementary Students With or At Risk for Reading Disabilities

For students who show inadequate response to research-based intervention, intensification of intervention using data-based decision making (DBDM) is recommended. There is a paucity of research on upper elementary students related to the efficacy of (a) word reading interventions and (b) DBDM procedures. This randomized controlled trial examined the differential effects of data use at two timepoints to intensify a multisyllabic word reading intervention for Grade 4 and 5 students with or at risk for reading disabilities (RD). Eighty-eight students were randomly assigned to one of three conditions: initial customization of the intervention (IC-only), initial customization with DBDM (IC + DBDM), or a business-as-usual comparison condition. Results indicated that (a) students in both treatment conditions outperformed the comparison condition on multisyllabic word reading and (b) students in the IC + DBDM condition also outperformed comparison students on decoding. Implications, including the use of DBDM in addition to IC-only as well as methods for decision-making within a small-group context, are discussed.

Data Mountain: Self-Monitoring, Goal Setting, and Positive Attributions to Enhance the Oral Reading Fluency of Elementary Students With or At-Risk for Reading Disabilities

Data Mountain is a self-determination program that has shown early promise in enhancing the oral reading fluency (ORF) of students with or at-risk for reading disabilities (RD). This program supports self-determined learning behaviors through explicit teaching of self-monitoring, goal setting, and positive attributions. The present study tested the effects of Data Mountain on the ORF of 81 students with or at-risk for RD in second through fifth grades, randomly assigned to one of three conditions: Data Mountain delivered in small groups, Data Mountain delivered individually, or a comparison condition. Results from hierarchical linear modeling indicated that treatment students read an average of 31 more words per minute with a growth rate twice that of comparison students ( p < .01). The transferable possibilities of Data Mountain to provide students with an opportunity to learn self-determination skills and support ORF is significant to the field of special education.

A Large-Scale Investigation of White Matter Microstructural Associations with Reading Ability

Reading involves the functioning of a widely distributed brain network, and white matter tracts are responsible for sending information between constituent network nodes. Several studies have analyzed fiber bundle microstructural properties to shed insights into the neural basis of reading abilities and disabilities. Findings have been inconsistent, potentially due to small sample sizes and varying methodology. To address this, we analyzed a large data set of 690 children ages 5-18 using state-of-the-art neuroimaging acquisitions and processing techniques. We searched for associations between fractional anisotropy (FA) and single-word and nonword reading skills in both typical and poor readers across multiple tracts previously thought to contribute to reading. Consistent with prior studies, FA increased with age across all tracts. There were significant correlations between better reading skills and higher FA in several fiber bundles among poor readers, but fewer and occasionally negative associations among proficient readers. The left superior longitudinal fasciculus and arcuate fasciculus unexpectedly exhibited higher FA within those diagnosed with reading disabilities compared to those without a diagnosis, while their right-hemisphere homologs exhibited higher FA in those with higher reading scores, regardless of diagnostic status. These results suggest a different relation between white matter pathways in children with typical reading ability versus those with reading disabilities.

Spatial attention in encoding letter combinations

Reading requires the correct identification of letters and letter positions within words. Selectiveattention is, therefore, required to select chunks of the text for sequential processing. Despite theextensive literature on visual attention, the well known effects of spatial cues in simpleperceptual tasks cannot inform us about the role of attention in a task as complex as reading.Here, we systematically manipulate spatial attention in a multi-letter processing task tounderstand the effects of spatial cues on letter encoding in typical adults. Overall, endogenous(voluntary) cue benefits were larger than exogenous (involuntary). We show that cue benefitsare greater in the left than in the right visual field; and larger for the most crowded letterpositions. Endogenous valid cues reduced errors due to confusing letter positions more thanmisidentifications, specifically for the most crowded letter positions. Therefore, shiftingendogenous attention along a line of text is likely an important mechanism to alleviate theeffects of crowding on letters within words. Our results help set the premise for buildingtheories for how specific mechanisms of attention support reading development in children.Understanding the link between reading development and attention mechanisms has farreaching implications in the remediation for children with reading disabilities.
