Spanish L2 Chinese Learners’ Awareness of Morpho-Syntactic Structures in the Reading Comprehension of Splittable Compounds

Reading comprehension is never considered a simple task in linguists’ views as it requires a full set of linguistic knowledge, such as word decoding, understanding syntactic and morphological structures, and deriving proper meanings from these structures in a given context. Bearing the simple view of reading, the primary goal of this study is to explore whether the split presentation of Chinese splittable compounds influences the recognition of the compounds in second language (L2) Chinese reading comprehension, and how the reading skills, i.e., word decoding and linguistic comprehension, cooperate to complete this reading comprehension task. Splittable compounds (SCs) in Chinese are typically verbs composed of two constituents with limited separability. The separable property of SCs and their vague morpho-syntactic status are supposed to cause difficulties for L2 Chinese learners in recognizing the compounds. Especially for those whose native language manifests lexical integrity, the split presentation of the compounds may invite the L2 Chinese readers to process them with a mechanism different from that for their non-split forms. To the best of our knowledge, the efforts on investigating this issue are insufficient. In this study, 27 Spanish speaking L2 Chinese learners were invited to complete tasks including reading and interpreting 6 selected SCs in the split and non-split forms, rating their familiarities with each SC and reporting the syntactic category of the SCs based on their existing linguistic knowledge. The results, showed that the split presentation of SCs did cause challenges for L2 Chinese learners in recognizing the compounds in the reading process, regardless of their Chinese proficiencies. The L2 Chinese participants performed significantly worse in recognizing split SCs in salient Verb-Object structures than recognizing those in unsalient Verb-Object structures. These findings underscore the importance of linguistic comprehension in L2 Chinese in-text word reading comprehension and suggest words as the basic processing units.

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.

Predicting Dyslexia and Reading Speed in Adolescents from Eye Movements in Reading and Non-Reading Tasks: A Machine Learning Approach

There is evidence that abnormalities in eye movements exist during reading in dyslexic individuals. A few recent studies applied Machine Learning (ML) classifiers to such eye movement data to predict dyslexia. A general problem with these studies is that eye movement data sets are limited to reading saccades and fixations that are confounded by reading difficulty, e.g., it is unclear whether abnormalities are the consequence or the cause of reading difficulty. Recently, Ward and Kapoula used LED targets (with the REMOBI & AIDEAL method) to demonstrate abnormalities of large saccades and vergence eye movements in depth demonstrating intrinsic eye movement problems independent from reading in dyslexia. In another study, binocular eye movements were studied while reading two texts: one using the “Alouette” text, which has no meaning and requires word decoding, the other using a meaningful text. It was found the Alouette text exacerbates eye movement abnormalities in dyslexics. In this paper, we more precisely quantify the quality of such eye movement descriptors for dyslexia detection. We use the descriptors produced in the four different setups as input to multiple classifiers and compare their generalization performances. Our results demonstrate that eye movement data from the Alouette test predicts dyslexia with an accuracy of 81.25%; similarly, we were able to predict dyslexia with an accuracy of 81.25% when using data from saccades to LED targets on the Remobi device and 77.3% when using vergence movements to LED targets. Noticeably, eye movement data from the meaningful text produced the lowest accuracy (70.2%). In a subsequent analysis, ML algorithms were applied to predict reading speed based on eye movement descriptors extracted from the meaningful reading, then from Remobi saccade and vergence tests. Remobi vergence eye movement descriptors can predict reading speed even better than eye movement descriptors from the meaningful reading test.

Word Decoding Abilities of 1st Graders with Developmental Dyslexia Considering Reading Severity and Word and Syllable Structure

Objectives: This study investigated word decoding abilities of 1st graders with Developmental dyslexia according to the level of decoding difficulty, meaning availability, word and syllable structure.Methods: Twenty Korean 1st graders with developmental dyslexia participated in 40 word-reading tasks individually. All of them had severe decoding difficulties, even with normal listening comprehension (KORLA; Pae et al., 2015) and intelligence (K-CTONI-2; Park, 2014). The group differences by decoding difficulties were compared considering the meaning of words, the number of syllable-final graphemes, and the position of each grapheme in a syllable.Results: Both the severe and less-severe group in Korean word-decoding difficulties revealed the gaps between word reading and nonword reading. Both groups had decoding difficulties when a word had syllable-final graphemes, while the severe group had even lower performances in word readings with 2 syllable-final graphemes. Both groups showed similar performances in reading syllable-initial graphemes while the severe group had lower performances both in reading syllable-medial vowel graphemes and syllable-final consonant graphemes compared to the less-severe group.Conclusion: Korean 1st graders with developmental dyslexia seemed to be in urgent need of decoding support considering word and syllable structure. Triggering the non-lexical route with non-words considering the grain size of syllable-medial vowel graphemes and syllable-final graphemes would facilitate word decoding abilities of severely dyslexic Korean children.

Reading Development in Children With Nonsyndromic Cleft Palate With or Without Cleft Lip: Meta-analysis and Systematic Review

Objective We conducted a meta-analysis and systematic review of literature comparing pre-reading and general reading in school-age children with nonsyndromic cleft palate with or without cleft lip (NSCP/L) to their peers without NSCP/L. Methods Our literature search identified 1238 possible records. After screening we identified 11 samples for inclusion for systematic review and eight for meta-analysis. We compared 292 children with NSCP/L to 311 peers for 23 pre-reading effect sizes and 17 general reading effect sizes (EFg). We conducted a random-effects metaregression using robust variance estimation. Results On average school-age children with NSCP/L scored lower on pre-reading (EFg = −0.36) and general reading measures (EFg = −0.38) compared to their peers. We conducted post-hoc analyses on phonological awareness and word decoding effect sizes; children with NSCP/L performed lower on phonological awareness (EFg = −0.22) and word decoding (EFg = −0.39) compared to their peers. There was weak evidence that hearing status and/or speech-language functioning might moderate reading development. There was limited evidence that age or socioeconomic status moderated reading development. However, samples did not consistently report several characteristics that were coded for this project. Conclusions Our findings suggest that school-age children with NSCP/L have persistent reading problems. Further research is needed to explore reading development in children with NSCP/L, as well as the relationships among hearing, speech, language, and reading development.

Exploring the importance of vocabulary for English as an additional language learners’ reading comprehension

This exploratory study represents an attempt to investigate the factors that may affect the reading comprehension abilities of English as an additional language (EAL) learners. For this study, we examined a participant group of 31 (25 EAL and 6 first language English) learners studying at an international school in Japan. We assessed the participants according to four factors shown to influence reading comprehension: vocabulary knowledge, word decoding skills, reading fluency, and general linguistic ability. Our results show that differences in vocabulary knowledge show more variance in reading comprehension scores than the other factors examined in this study, highlighting the importance of vocabulary knowledge for reading comprehension. However, other factors such as reading fluency and general linguistic knowledge are also shown to be moderate to strong predictors of reading comprehension. Based on these results, we suggest that EAL learners need targeted language support to enhance academic text comprehension.

Digital Game-Based Phonics Instruction Promotes Print Knowledge in Pre-Readers at Cognitive Risk for Dyslexia

Dyslexia is targeted most effectively when (1) interventions are provided preventively, before the onset of reading instruction, and (2) remediation programs combine letter-sound training with phoneme blending. Given the growing potential of technology in educational contexts, there has been a considerable increase of letter-sound trainings embedded in digital serious games. One such intervention is GraphoGame. Yet, current evidence on the preventive impact of GraphoGame is limited by the lack of adaptation of the original learning content to the skills of pre-readers, short training duration, and a restricted focus on explicitly trained skills. Therefore, the current study aims at investigating the impact of a preventive, and pre-reading adapted GraphoGame training (i.e., GraphoGame-Flemish, GG-FL) on explicitly trained skills and non-specifically trained phonological and language abilities. Following a large-scale screening (N = 1225), the current study included 88 pre-reading kindergarteners at cognitive risk for dyslexia who were assigned to three groups training either with GG-FL (n = 31), an active control game (n = 29), or no game (n = 28). Before and after the 12-week intervention, a variety of reading-related skills were assessed. Moreover, receptive letter knowledge and phonological awareness were measured every three weeks during the intervention period. Results revealed significantly larger improvements in the GG-FL group on explicitly trained skills, i.e., letter knowledge and word decoding, without finding transfer-effects to untrained phonological and language abilities. Our findings imply a GG-FL-driven head start on early literacy skills in at-risk children. A follow-up study should uncover the long-term impact and the ability of GG-FL to prevent actual reading failure.

Dyslexics’ Fragile Oculomotor Control Is Further Destabilized by Increased Text Difficulty

Dyslexic adolescents demonstrate deficits in word decoding, recognition, and oculomotor coordination as compared to healthy controls. Our lab recently showed intrinsic deficits in large saccades and vergence movements with a Remobi device independent from reading. This shed new light on the field of dyslexia, as it has been debated in the literature whether the deficits in eye movements are a cause or consequence of reading difficulty. The present study investigates how these oculomotor problems are compensated for or aggravated by text difficulty. A total of 46 dyslexic and 41 non-dyslexic adolescents’ eye movements were analyzed while reading L’Alouette, a dyslexia screening test, and 35 Kilos D’Espoir, a children’s book with a reading age of 10 years. While reading the more difficult text, dyslexics made more mistakes, read slower, and made more regressive saccades; moreover, they made smaller amplitude saccades with abnormal velocity profiles (e.g., higher peak velocity but lower average velocity) and significantly higher saccade disconjugacy. While reading the simpler text, these differences persisted; however, the difference in saccade disconjugacy, although present, was no longer significant, nor was there a significant difference in the percentage of regressive saccades. We propose that intrinsic eye movement abnormalities in dyslexics such as saccade disconjugacy, abnormal velocity profiles, and cognitively associated regressive saccades can be particularly exacerbated if the reading text relies heavily on word decoding to extract meaning; increased number of regressive saccades are a manifestation of reading difficulty and not a problem of eye movement per se. These interpretations are in line with the motor theory of visual attention and our previous research describing the relationship between binocular motor control, attention, and cognition that exists outside of the field of dyslexia.

Reading Skills in Down Syndrome: Implications for Clinical Practice

Though children with Down syndrome can learn to read, they may have difficulty developing some component skills, including phonological awareness and word decoding. Given reading's foundation in language, speech-language pathologists (SLPs) should play a central role in supporting access to and providing reading instruction for children with Down syndrome. This article reviews the available research on reading in Down syndrome and offers guidance for SLPs working with this population. We start by reviewing the Down syndrome phenotype, highlighting physical features and cognitive and linguistic patterns of strength and weakness that impact reading development. Next, we define different reading subskills and outline typical reading development, including stages of prereading, learning to read, and transitioning to using reading as a tool for learning. We then use these stages to review what is known about reading in Down syndrome, including relevant intervention work. We also incorporate considerations for clinical practice. In particular, we encourage SLPs to advocate for supporting reading development in children with Down syndrome, to work with families to develop rich home literacy environments, and to work with educators to promote phonological awareness and decoding skills. Lastly, we note limitations in our current knowledge and include a call for more research.

Evidence for complementary effects of code- and knowledge-focused reading instruction

There is growing recognition of the need to end the debate regarding reading instruction in favor of an approach that provides a solid foundation in phonics and other underlying language skills to become expert readers. We advance this agenda by providing evidence of specific effects of instruction focused primarily on the written code or on developing knowledge. In a grade 1 program evaluation study, an inclusive and comprehensive program with a greater code-based focus called Reading for All (RfA) was compared to a knowledge-focused program involving Dialogic Reading. Phonological awareness, letter word recognition, nonsense word decoding, listening comprehension, reading comprehension, written expression and vocabulary were measured at the beginning and end of the school year, and one year after in one school only. Results revealed improvements in all measures except listening comprehension and vocabulary for the RfA program at the end of the first school year. These gains were maintained for all measures one year later with the exception of an improvement in written expression. The Dialogic Reading group was associated with a specific improvement in vocabulary in schools from lower socioeconomic contexts. Higher scores were observed for RfA than Dialogic Reading groups at the end of the first year on nonsense word decoding, phonological awareness and written expression, with the differences in the latter two remaining significant one year later. The results provide evidence of the need for interventions to support both word recognition and linguistic comprehension to better reading comprehension.
