Metalinguistic and Reading Skills in a Sample of Colombian Children with Attention Deficit Hyperactivity Disorder

Objective: This study aimed to examine metalinguistic skills and reading processes in children diagnosed with ADHD, compared to a matched control group. Method: An explanatory experimental design was employed, involving a sample of 194 children from Manizales, comprising 97 children diagnosed with ADHD and 97 controls. The study utilized tasks from the Children’s Neuropsychological Assessment (CNA) protocol to assess metalinguistic and reading abilities. Results: Children with ADHD exhibited significantly lower performance across all metalinguistic and reading tasks compared to the control group, except for spelling and silent reading comprehension tasks. Conclusions: These findings corroborate previous research conducted in Manizales, underscoring the specific challenges in metalinguistic and reading domains among children with ADHD. Future research should explore the influence of working memory on phonological awareness and its implications for metalinguistic skills and reading development.

Lexical processing in children with hearing impairment in oral word reading in transparent Arabic orthography

AbstractWord recognition mechanisms constitute an essential contribution to reading achievement in both deaf and hearing children. Little is known about how children with hearing impairment (HI) manage to read aloud words in the vowelled Arabic transparent script which provides full vowel information. This study aimed to compare word and pseudoword reading accuracy and speed between 32 Lebanese children with HI and 32 younger hearing Lebanese children. The two groups were carefully matched for reading comprehension and oral comprehension levels. Length, word frequency, and lexicality effects were assessed to characterize the functioning of the lexical and sublexical reading procedures. Reading errors were also analyzed to document reading difficulties in transparent Arabic orthography in the sublexical route. The results show significant effects of length, word frequency, and lexicality on reading accuracy and speed in both groups. They also indicate underdeveloped sublexical and lexical routes in children with HI who read less accurately and faster than the younger hearing children. Reading errors are numerous in children with HI. The data are discussed in light of the Dual Route Cascaded model. Suggestions are made about how to improve reading processes in children with HI.

Morphological awareness and its role in early word reading in English monolinguals, Spanish-English, and Chinese-English simultaneous bilinguals.

Words' morphemic structure and their orthographic representations vary across languages. How do bilingual experiences with structurally distinct languages influence children's morphological processes for word reading? Focusing on English literacy in monolinguals and bilinguals (N = 350, ages 5-9), we first revealed unique contributions of derivational ( friend-li-est) and compound (girl-friend) morphology to early word reading. We then examined mechanisms of bilingual transfer in matched samples of Spanish-English and Chinese-English dual first language learners. Results revealed a principled cross-linguistic interaction between language group (Spanish vs. Chinese bilinguals) and type of morphological awareness. Specifically, bilinguals' proficiency with the type of morphology that was less characteristic of their home language explained greater variance in their English literacy. These findings showcase the powerful effects of bilingualism on word reading processes in children who have similar reading proficiency but different language experiences, thereby advancing theoretical perspectives on literacy across diverse learners.

Brain Source Correlates of Speech Perception and Reading Processes in Children With and Without Reading Difficulties.

Neural correlates in reading and speech processing have been addressed extensively in the literature. While reading skills and speech perception have been shown to be associated with each other, their relationship remains debatable. In this study, we investigated reading skills, speech perception, reading, and their correlates with brain source activity in auditory and visual modalities. We used high-density event-related potentials (ERPs), fixation-related potentials (FRPs), and the source reconstruction method. The analysis was conducted on 12–13-year-old schoolchildren who had different reading levels. Brain ERP source indices were computed from frequently repeated Finnish speech stimuli presented in an auditory oddball paradigm. Brain FRP source indices were also computed for words within sentences presented in a reading task. The results showed significant correlations between speech ERP sources and reading scores at the P100 (P1) time range in the left hemisphere and the N250 time range in both hemispheres, and a weaker correlation for visual word processing N170 FRP source(s) in the posterior occipital areas, in the vicinity of the visual word form areas (VWFA). Furthermore, significant brain-to-brain correlations were found between the two modalities, where the speech brain sources of the P1 and N250 responses correlated with the reading N170 response. The results suggest that speech processes are linked to reading fluency and that brain activations to speech are linked to visual brain processes of reading. These results indicate that a relationship between language and reading systems is present even after several years of exposure to print.

Global reading processes in children with high risk of dyslexia: a scanpath analysis.

The study presents the first systematic comparison of the global reading processes via scanpath analysis in Russian-speaking children with and without reading difficulties. First, we compared basic eye-movement characteristics in reading sentences in two groups of children in grades 1 to 5 (N = 72 in high risk of developmental dyslexia group and N = 72 in the control group). Next, using the scanpath method, we investigated which global reading processes these children adopt to read the entire sentence and how these processes differ between the groups. Finally, we were interested in the timeframe of the change in the global reading processes from the 1st to the 5th grades for both groups. We found that the main difference in word-level measures between groups was the reading speed reflected in fixation durations. However, the examination of the five identified global reading processes revealed qualitative similarities in reading patterns between groups. Children in the control group progressed quickly and by the 4th grade engaged in an adult-like fluent reading process. The high-risk group started with the beginner reading process, then similar to first graders in the control group, engaged mostly in the intermediate and upper-intermediate reading processes in 2nd to 4th grades. They reach the advanced process in the 5th grade, the same pattern preferred by the control group second graders. Overall, the scanpath analysis reveals that although there are quantitative differences in the word-level eye-tracking measures between groups, qualitatively children in the high-risk group read on par with typically developing peers but with a 3-year reading delay.

Eyetrackingowe badanie weryfikacyjne procesu czytania u dzieci ryzyka dysleksji – analiza przypadków

The text presents an extract of an eye tracking verification study of the reading process in children with the risk of dyslexia. A case study analysis was used. The study revealed differences and irregularities between children with the risk of dyslexia and their peers in areas such as: number of fixations, length of fixations and length of observation of text. It was observed that the intensity of difficulties associated with the reading skills does not have to be proportional to the irregularities of the movements of the eye balls (for instance, serious decrease in the reading skills with insignificant improper movements of the eyes) but visual perception of the text being processed varies, which is graphically presented in the text.

Parallel and serial reading processes in children’s word and nonword reading.

Fluent reading is characterized by rapid and accurate identification of words. It is commonly accepted that such identification relies on the availability of orthographic knowledge. However, whether this orthographic knowledge should be seen as an accumulation of word-specific knowledge in a lexicon acquired through decoding or as a well-developed associative network of sublexical units is still under debate. We studied this key issue in reading research by looking at the serial and/or parallel reading processes underlying word and nonword reading. Participants were 314 Dutch 2nd, 3rd, and 5th graders. The children were administered digit, word, and nonword naming tasks. We used latent class analyses to distinguish between readers who processed the letter strings serially or in parallel, based on the correlation patterns of word and nonword reading with serial and discrete digit naming. The 2 classes of readers were distinguished for both word and nonword reading. The validity of these classes was supported by differences in sensitivity to word and nonword length. Interestingly, the different classes seemed to reflect a developmental shift from reading all letter strings serially toward parallel processing of words, and later of nonwords. The results are not fully in line with current theories on the representation of orthographic knowledge. Implications in terms of models of the reading process are discussed.

The time course of reading processes in children with and without dyslexia: an ERP study

The main diagnostic criterion for developmental dyslexia (DD) in transparent orthographies is a remarkable reading speed deficit, which is often accompanied by spelling difficulties. These deficits have been traced back to both deficits in orthographic and phonological processing. For a better understanding of the reading speed deficit in DD it is necessary to clarify which processing steps are degraded in children with DD during reading. In order to address this question the present study used EEG to investigate three reading related ERPs: the N170, N400 and LPC. Twenty-nine children without DD and 52 children with DD performed a phonological lexical decision (PLD)—task, which tapped both orthographic and phonological processing. Children were presented with words, pseudohomophones, pseudowords and false fonts and had to decide whether the presented stimulus sounded like an existing German word or not. Compared to control children, children with DD showed deficits in all the investigated ERPs. Firstly, a diminished mean area under the curve for the word material-false font contrasts in the time window of the N170 was observed, indicating a reduced degree of print sensitivity; secondly, N400 amplitudes, as suggested to reflect the access to the orthographic lexicon and grapheme-phoneme conversion, were attenuated; and lastly, phonological access as indexed by the LPC was degraded in children with DD. Processing differences dependent on the linguistic material in children without DD were observed only in the LPC, suggesting that similar reading processes were adopted independent of orthographic familiarity. The results of this study suggest that effective treatment should include both orthographic and phonological training. Furthermore, more longitudinal studies utilizing the same task and stimuli are needed to clarify how these processing steps and their time course change during reading development.

Developmental Stages of Reading Processes in Children who are Blind and Sighted

This article compares the development of print and braille reading in children who are blind and sighted in relation to Chall's stage model of reading development. Chall's model includes a prereading period, in which concepts are developed; middle stages, in which skills that are necessary for decoding text are developed; and later stages, which distinguish skilled readers on the basis of their highly developed schemata and cognitive skills that are necessary for effective comprehension and integration. The relevance of a developmental theory for directing training methods that facilitate braille literacy instruction is discussed.

Atypical brain activation of reading processes in children with developmental dyslexia.

Brain activation differences of reading-related processes between dyslexic and normal reading children were localized with functional magnetic resonance imaging (MRI). The children performed tasks that varied in visuospatial, orthographic, phonologic, and semantic processing demands. Enhanced activation of the left extrastriate cortex was found during all tasks in the dyslexic group. During orthographic processing, dyslexic children predominantly showed activation in the right prefrontal cortex, as also occurred during the visuo-spatial task. Normal readers also showed activation in the left prefrontal cortex. Dyslexic readers showed less activation of both the temporal and the prefrontal cortex during phonologic processing. The results suggest that dyslexic readers fail to use brain areas that are normally specialized in language processing, but rather use areas that underlie visuospatial processing.
