The relation of bilingual cognitive skills to the second language writing performance of primary grade students.

The purposes of the current study were to examine the effects of cognitive and reading skills (i.e., working memory [WM], oral language development [OLD], and reading skills) on second language (L2) writing performance as well as the changes in these relationships across different grades among Spanish-speaking children learning English. A battery of measures assessing English and Spanish WM, OLD, reading skills, and English writing were administered to 494 English learners in Grades 1 to 3. Path analysis was conducted for each grade separately in both English and Spanish models. The findings indicated that the relationships between English writing performance and English cognitive and reading skills became stronger as the grades increased. However, the relationships between English writing and the Spanish cognitive and reading determinants were mixed, indicating a statistically significant relationship with Spanish WM and reading skills for Grade 2 and 3 students but not with OLD across all grades. Implications for L2 writing development are discussed.

The power of the written word: Comparing word meaning inferencing from auditory and written modalities throughout grade school.

Previous research indicates that word learning from auditory contexts may be more effective than written context at least through fourth grade. However, no study has examined contextual differences in word learning in older school-aged children when reading abilities are more developed. Here we examined developmental differences in children's ability to deduce the meanings of unknown words from the surrounding linguistic context in the auditory and written modalities and sought to identify the most important predictors of success in each modality. A total of 89 children aged 8-15 years were randomly assigned to either read or listen to a narrative that included eight novel words, with five exposures to each novel word. They then completed three posttests to assess word meaning inferencing. Children across all ages performed better in the written modality. Vocabulary was the only significant predictor of success on the word inferencing task. Results indicate support for written stimuli as the most effective modality for novel word meaning deduction. Our findings suggest that the presence of orthographic information facilitates novel word learning even for early, less proficient readers.

Discourse coherence modulates use of predictive processing during sentence comprehension.

Context has been shown to be vitally important for comprehension. Lexical processing is facilitated when words are highly predictable given their local sentence context, suggesting that people pre-activate likely upcoming words to aid comprehension. However, this facilitation is affected by knowledge about the global context in which comprehension takes place: people predict less when in an environment where expectations are frequently violated. The current study investigated whether discourse coherence is an additional cue that comprehenders use to modulate lexical prediction. In a series of online, self-paced reading experiments, participants read target sentences preceded by short contextual preambles. Local facilitation effects were manipulated through the cloze probability of a critical word within the target sentence and discourse coherence was manipulated by varying the degree to which the target sentence was consistent with the information presented in the preamble. In the first two experiments, target sentences were read more slowly when they occurred in less coherent discourses, but no local facilitation effects were observed. In the third experiment, we strengthened the predictability manipulation by using semantically anomalous critical words. In this experiment, predictable words were processed more quickly and anomalous words more slowly when they occurred in highly coherent discourse. Our results suggest that comprehenders are sensitive to shifts in the topic of discourse and that they downregulate predictive processing when they encounter incoherence in the discourse. This is consistent with recent theoretical accounts suggesting that comprehenders flexibly engage in predictive processing, pre-activating semantic and lexical information less when their expectations are less likely to be reliable.

Some scales require cognitive effort: A systematic review on the role of working memory in scalar implicature derivation.

If some inferences require cognitive effort, could that mean, that all of them do? The scalar term "some" has long fascinated academics from various backgrounds, as it can be interpreted either purely semantically, as "some and possibly all", or pragmatically, as "some and not all". The pragmatic reading implies the generation of what is called a scalar implicature. While scientific investigation of such implicatures has given rise to many potential explanations of the "pragmatic enrichment" phenomenon behind them, the debate between the two dominant frameworks-the literal-first and the default accounts-has not convincingly been settled. With the birth of a new interdisciplinary field, appropriately dubbed experimental pragmatics, the last 20 years have led to a substantial amount of new empirical data on scalar implicatures. In this ongoing investigation, the loading and measuring of Working Memory has become an important experimentation tool, as it allows to test the contrasting hypotheses with regard to the cognitive effort of implicature generation, which are made by the two main theoretical accounts. The current systematic review evaluates the relevant literature until March 08, 2022 in an attempt to shed light on the role of Working Memory in implicature derivation. A comprehensive search, and two-step review procedure yielded a sample of 18 studies, containing data of 23 relevant experiments. Findings were bundled in a narrative synthesis and combined through two separate meta-analyses. Our results support the literal-first account, by showing that the derivation of scalar implicatures is a cognitively effortful process that is sensitive to changes in the available Working Memory resources. However, as the reported effects are relatively weak and capricious, we argue that the development of more sophisticated paradigms and eventually, stronger theories within the field, will be crucial in order to both fully understand the current results and set-up fruitful future research.

The reading brain extracts syntactic information from multiple words within 50 milliseconds.

To what extent do readers process multiple words in parallel? Although it is now commonly accepted that letters are processed across multiple words simultaneously, higher-order (lexical, semantic, syntactic) parallel processing remains contentious. Recent use of the flanker paradigm has revealed that the syntactic recognition of foveal target words is influenced by the syntactic congruency of parafoveal flanking words even when target and flankers are shown for only 170 ms. It has been argued, however, that such settings may allow processing of multiple words even if this were to happen on a serial one-by-one basis. To circumvent this possibility, here I have tested participants in a syntactic categorization task whereby targets and flankers were shown for only 50 ms and replaced by post-masks. Significant effects of target-flanker congruency were observed in both response times and accuracy, indicating that readers extracted syntactic information from multiple words within the very brief presentation time. The present results strongly suggest that the brain extracts higher-order linguistic information from multiple words in parallel.

Developmental dysplasia of the hip and ultrasound reading by pediatric orthopedic surgeons: a pilot study.

Ultrasound is an imaging modality utilized for early detection and follow-up of developmental dysplasia of the hip (DDH) in infants. Traditionally, pediatric orthopedic surgeons have relied on radiologists to perform ultrasound examinations and interpret the imaging. Today, however, many orthopedic surgeons are performing and interpreting ultrasound themselves. The purpose of this paper was to evaluate the reliability of pediatric orthopedic surgeons in interpreting ultrasound imaging of infant hips. This was a prospective observational pilot study. After reading an instructional handout about the Graf method of hip ultrasonography, eight pediatric orthopedic surgeons measured 28 hip ultrasound images to determine the alpha angle and percent femoral head coverage. On the basis of cited intraclass correlation coefficient cutoff values, interrater reliability was found to be 'good' for percent femoral head coverage and 'fair' for alpha angle. These findings are equivalent to findings of similar studies using radiologists as examiners. Pediatric orthopedic surgeons can interpret ultrasound exams for diagnosing DDH.

Alkaline surface treatment and time-resolved reading of mn-doped nanocrystal signal transducer for enhanced bioassay sensitivity.

Recently, Mn-doped semiconductor nanocrystals (NCs) with high brightness, long lifetimes, and low-energy excitation are emerging for time-resolved luminescence biosensing/imaging. Following our previous work on Mn-doped NCs, in this work we developed poly(styrene-co-maleic anhydride) (PSMA)-encapsulated Mn-doped AgZnInS/ZnS NCs as signal transducers for immunoassay of capsular polysaccharide (CPS), a surface antigen and also a biomarker of Burkholderia pseudomallei which causes a fatal disease called melioidosis. To enhance the assay sensitivity, a surface treatment for PSMA-encapsulated NCs (NC-probes) was performed to promote the presence of carboxyl groups that help conjugate more anti-CPS antibodies to the surface of NC-probes and thus enhance bioassay signals. Meanwhile, time-resolved reading on the luminescence of NC-probes was adopted to minimize the assay background autofluorescence. Both strategies essentially enhance the assay signal-to-background ratio (or equivalently the assay sensitivity) by increasing the signal and decreasing the background, respectively. Through performing and comparing immunoassays with different NC-probes (with and without surface treatment) and different signal reading methods (time-resolved reading and non-time-resolved reading), it was proven that the immunoassay adopting surface-treated NC-probes and time-resolved reading achieved a lower limit-of-detection (LOD) than the ones adopting non-surface-treated NC-probes or non-time-resolved reading. Moreover, the achieved LOD is comparable to the LOD of immunoassay using enzyme horseradish peroxidase as a signal transducer.

Tratamiento psicológico de la tartamudez crónica: estudio descriptivo de cinco casos clínicos / Psychological treatment of persistent stuttering: Descriptive study of five clinical cases

La tartamudez persistente se define por la permanencia de las disfluencias y la presencia de factores cognitivos, conductuales y comunicativos que contribuyen a mantenerla y agravarla. Por tanto, su tratamiento clínico debe centrarse en mejorar la fluidez del habla, asegurar la generalización del nuevo patrón prosódico y manejar los pensamientos disfuncionales y las conductas de evitación social y comunicativa que ayudan a mantener el problema y provocan una pérdida significativa de calidad de vida. Objetivo: Medir la eficacia de un tratamiento estandarizado para pacientes adultos con tartamudez persistente centrado en la fluidez de habla y en los aspectos psicológicos implicados. Material y métodos: Estudio clínico analítico de los resultados de la intervención. Se realizó una evaluación de todos los aspectos implicados en la tartamudez persistente mediante instrumentos validados y registro de habla. Se aplicó el protocolo de un tratamiento para tartamudez crónica. Resultados: Se evaluó la fluidez del habla en muestras de habla espontánea y lectura y las subescalas del cuestionario OASES de cinco pacientes con tartamudez de entre 21 y 25años. El tratamiento redujo el porcentaje de sílabas tartamudeadas en todos los casos, tanto en habla como en lectura, así como una reducción de las puntuaciones en todas las subescalas del OASES. Conclusión: Los resultados clínicos obtenidos indican eficacia del protocolo empleado para la modificación de la frecuencia de tartamudeos y de otros fenómenos asociados. Se exponen algunas consideraciones de interés para los terapeutas de la tartamudez crónica.(AU)

Persistent stuttering is defined by the permanence of disfluencies and the presence of cognitive, behavioral, and communication factors that contribute to maintaining and aggravating it. Therefore, clinical treatment should focus on improving speech fluency, ensuring generalization of the new prosodic pattern, and managing dysfunctional thoughts and social and communicative avoidance behaviors that help maintain the problem and cause significant loss of quality of life in patients. Objective: The main objective is to measure the efficacy of a standardized treatment focused on speech fluency and psychological aspects for adult patients with persistent stuttering. Material and methods: Analytical clinical study of the results of the psychological intervention. An evaluation of all aspects involved in persistent stuttering was carried out using validated instruments and speech recording. The protocol of a clinical treatment for chronic stuttering was applied. Results: Speech fluency in spontaneous speech and reading samples and the OASES questionnaire subscales from five stuttering patients aged 21-25years were assessed. The treatment reduced the percentage of stuttered syllables in all cases, both in speaking and reading, as well as a reduction in scores on all OASES subscales. Conclusion: Clinical results obtained indicate the efficacy of the protocol used to modify the frequency of stuttering and other associated behaviors. Some considerations of interest for therapists of chronic stuttering are exposed.(AU)

El objetivo de este trabajo es analizar el rendimiento en lectura y escritura en estudiantes españoles, tras su intervención desde edades tem-pranas. La finalidad de la intervención es priorizar y sistematizar la instruc-ción en principio alfabético, conciencia fonológica, fluidez lectoescritora, vocabulario y comprensión textual. La muestra está formada por 126 suje-tos, distribuidos en grupo instruido (n=62) y grupo no instruido (n=64), pertenecientes a zonas socioculturales medias, con inteligencia normal y sin déficits físicos, psíquicos y/o sensoriales. Los sujetos son evaluados desde 2º curso de Educación Infantil(cuatro años) hasta 1º curso de Educación Primaria (seis años). El diseño es longitudinal con medidas repetidas (cua-tro evaluaciones), tres fases de intervención y dos variables de estudio (Rendimiento en Lectura y Rendimiento en Escritura) y dos grupos de su-jetos. Se realizan análisis estadísticos descriptivos y análisis de varianza de medidas repetidas. Los resultados obtenidos indican mejores puntuaciones en lectura y escritura a lo largo de todas las evaluaciones y un avance signi-ficativamente mayor enel grupo instruido. Estos resultados demuestran la eficacia de una intervención temprana del lenguaje escrito a través de la ins-trucción sistemática en conciencia fonológica, principio alfabético, fluidez lectoescritora, vocabulario y comprensión textual.(AU)

The aim of this paper is to analyse the reading and writing achievement of Spanish school children following an intervention con-ducted at an early age. The purpose of the intervention is to prioritise and systematise instruction in the alphabetic principles, phonological aware-ness, reading fluency, vocabulary, and text comprehension. The sample consists of 126 subjects, distributed between an instructed group(n=62) and an uninstructed group (n=64). All the subjects were from average so-cio-cultural areas, with normal intelligence and with no physical, mental, and/or sensory deficits. Subjects were evaluated from the second year of Early Years Education (4 years of age) up to the first year of Primary Edu-cation (six years of age). The design was longitudinal with repeated meas-urements (four assessments), three intervention phases, two study variables (reading achievement and writing achievement), and two groups of sub-jects. Descriptive statistical analysis and repeated measures analyses of var-iance were performed. The results obtained indicate higher scores in read-ing and writing throughout all the assessments and significantly greater progress in the instructed group. These results demonstrate the effective-ness of early intervention in written language through systematic instruc-tion in phonological awareness, the alphabetic principles, reading fluency, vocabulary, and text comprehension.(AU)

Reading performance in Portuguese children from second to tenth grade with the MNREAD reading acuity test

Purpose: To assess reading performance and report normative values for normal sighted Portuguese schoolchildren using the Portuguese version of the MNREAD reading acuity chart. Methods Children in the 2nd, 4th, 6th, 8th, and 10th grade in Portugal were recruited for this study. One hundred and sixty-seven children from 7 to 16 years of age participated. The Portuguese version of the printed MNREAD reading acuity chart was used to measure reading performance in these children. The non-linear mixed effects model with negative exponential decay function was used to compute maximum reading speed (MRS) and critical print size (CPS) automatically. Reading acuity (RA) and reading accessibility index (ACC) were computed manually. Results The mean MRS in words-per-minute (wpm) for the 2nd grade was 55 wpm (SD = 11.2 wpm), 104 wpm (SD = 27.9) for the 4th grade, 149 wpm (SD = 22.5) for 6th grade, 172 wpm (SD = 24.6) for 8th grade and 180 wpm for the 10th grade (SD = 16.8). There was a significant difference in MRS between school grades (p < 0.001). Participants’ reading speed increased by 14.5 wpm (95% CL: 13.1–15.9) with each year of increase in age. We found a significant difference between RA and school grades, but not for CPS. Conclusions This study provides normative reading performance values for the Portuguese version of the MNREAD chart. The MRS increased with increasing age and school grade, while RA shows initial improvement from early school years and gradually stabilizes in the more mature children. Normative values for the MNREAD test can now be used to determine reading difficulties or slow reading speed in, for example, children with impaired vision. (AU)

'What makes you say so?' Metacognition improves the sustained learning of inferential reading skills in English as a second language.

PURPOSE: This quasi-experimental study investigates the impact of enhancing metacognition in learning inferential reading skills in English as a second language. PROCEDURES: Six Grade 4 classes were randomly assigned to two groups. The "Control group" received an instructional unit on inferential reading skills. The "Metacognition group" received the same unit, including metacognitive activities. Students were assessed in metacognitive and inferential reading skills before (pre-test), immediately after (post-test) and four weeks after the intervention (deferred test). FINDINGS: Metacognitive strategy instruction enhanced student learning of inferential reading skills and its sustainability in time. The Metacognition group attained a significantly higher average score in deploying metacognitive skills both in the post and deferred tests, indicating that the intervention was effective, as intended, to this end. While both groups significantly improved their proficiency in inferential reading skills after working with the provided instructional unit, there was a significant difference in the Metacognition group, which outperformed the Control one, even more strongly in the deferred test. CONCLUSIONS: Findings support the importance of deliberately promoting metacognition as it positively impacts learning outcomes and sustainability.

Exam stress and the metacognitive strategies of reading in students with dyslexia: The role of motivational mechanisms and educational support.

Despite numerous studies on dyslexia, there is still a lack of empirical data on the factors determining the functioning of students with dyslexia in the context of written exams. Therefore, the aim of the study is to identify the relationship between sources of stress in an exam situation and the reported use of reading strategies by dyslexic students in terms of motivation and therapeutic interventions in the educational environment. This descriptive-analytical study used data from a larger project focused on children with and without dyslexia. The research sample (n = 640) included girls (n = 280) and boys (n = 360) aged between 14 and 15 years (M = 14.40, SD = 0.55), attending the 7th or 8th grade in Polish mainstream primary schools. Random and intentional sampling was used. All students completed four questionnaires. The results were analyzed using regression analysis in Model templates for PROCESS v4 for SPSS by Hayes. The study showed significant weak and moderate positive correlations between the sources of exam stress and the reading strategies reported by students, ranging from 0.186 to 0.570, as well as significant moderate and strong correlations between reading strategies and experienced educational support, ranging from 0.229 to 0.505, and between reading strategies and motivation to read, ranging from 0.582 to 0.701. The type of stress source significantly influenced the selection of specific reading strategies. Motivation acted as a mediator, while educational support was a moderator in the relationship between exam stress and the reported use of reading strategies. Based on our results, the source of stress may be perceived as factors activating metacognitive mechanisms aimed at selecting appropriate strategies for working with texts. Researchers and teachers should be aware of the need to undertake activities to support students with dyslexia focused on developing the ability to recognize the sources of exam stress and select effective coping strategies.

Efficacy οf Wet Age-related Macular Degeneration Treatment οn Reading: A Pilot Study Using Eye-movement Analysis.

SIGNIFICANCE: Functional vision, as evaluated with silent passage reading speed, improves after anti-vascular endothelial growth factor (anti-VEGF) treatment in patients with wet age-related macular antidegeneration (wAMD), reflecting primarily a concomitant reduction in the number of fixations. Implementing eye movement analysis when reading may better characterize the effectiveness of therapeutic approaches in wAMD. PURPOSE: This study aimed to evaluate silent reading performance by means of eye fixation analysis before and after anti-VEGF treatment in wAMD patients. METHODS: Sixteen wAMD patients who underwent anti-VEGF treatment in one eye and visual acuity (VA) better than 0.5 logMAR served as the AMD group. Twenty adults without ocular pathology served as the control group. Central retinal thickness and near VA were assessed at baseline and 3 to 4 months after their first visit. Reading performance was evaluated using short passages of 0.4-logMAR print size. Eye movements were recorded using EyeLink II video eye tracker. Data analysis included computation of reading speed, fixation duration, number of fixations, and percentage of regressions. Frequency distributions of fixation durations were analyzed with ex-Gaussian fittings. RESULTS: In the AMD group, silent reading speed in the treated eye correlated well with central retinal thickness reduction and improved significantly by an average of 15.9 ± 28.5 words per minute (P = .04). This improvement was accompanied by an average reduction of 0.24 ± 0.38 in fixations per word (P = .03). The corresponding improvement in monocular VA was not statistically significant. Other eye fixation parameters did not change significantly after treatment. No statistically significant differences were found in the control group. CONCLUSIONS: Visual acuity tests may underestimate the potential therapeutic effects after anti-VEGF treatment in patients with relatively good acuity who are being treated for wAMD. Evaluating silent reading performance and eye fixation parameters may better characterize the effectiveness of therapeutic approaches in wAMD patients.

Release of Histone H3K4-reading transcription factors from chromosomes in mitosis is independent of adjacent H3 phosphorylation.

Histone modifications influence the recruitment of reader proteins to chromosomes to regulate events including transcription and cell division. The idea of a histone code, where combinations of modifications specify unique downstream functions, is widely accepted and can be demonstrated in vitro. For example, on synthetic peptides, phosphorylation of Histone H3 at threonine-3 (H3T3ph) prevents the binding of reader proteins that recognize trimethylation of the adjacent lysine-4 (H3K4me3), including the TAF3 component of TFIID. To study these combinatorial effects in cells, we analyzed the genome-wide distribution of H3T3ph and H3K4me2/3 during mitosis. We find that H3T3ph anti-correlates with adjacent H3K4me2/3 in cells, and that the PHD domain of TAF3 can bind H3K4me2/3 in isolated mitotic chromatin despite the presence of H3T3ph. Unlike in vitro, H3K4 readers are still displaced from chromosomes in mitosis in Haspin-depleted cells lacking H3T3ph. H3T3ph is therefore unlikely to be responsible for transcriptional downregulation during cell division.

[The benefits of reading aloud in geriatric wards and institutions]. / Les bienfaits de la lecture à voix haute dans les services et institutions de gériatrie.

The number of elderly patients hospitalized in geriatric wards and institutions on a temporary or more permanent basis is increasing. We know that thymic symptoms, such as depression, behavioral disorders and boredom, are common in these patients. We also know that the drug therapies used to treat these symptoms are sometimes a source of iatrogenesis and can be ineffective. That's why "non-drug" therapies are so useful. What if reading aloud could be part of the management of our elderly patients?

Knowing the learning strategy is not enough to use it: Example in reading strategies for Japanese undergraduates.

Learning strategies are an important component of self-regulated learning. Learners are expected to use multiple strategies appropriately. This study focused on metacognitive knowledge in the use of learning strategies and attempted to clarify the hierarchical nature of multiple knowledge. Furthermore, the study provided suggestions that could lead to further efficient acquisition of learning strategies. Responses were obtained from 184 Japanese university students regarding the degree of strategy use, knowledge regarding strategy, and perceived benefit and cost of 28 reading strategies. Results of the hierarchical Bayesian modeling showed that strategy use was influenced by knowledge regarding strategy and perceived benefit and cost. Furthermore, the effects of perceived benefit and cost were lower in the absence of knowledge regarding strategy. This implies that to use a learning strategy, the learner must first be aware of it and the degree to which it is used (apart from its theoretical usefulness) is determined by subjective benefit and cost. Therefore, in classroom situations, it is desirable to explicitly teach not only the course content but also strategies appropriate for learning the content. Dependence of the effects of perceived benefit and cost of strategy use on the presence or absence of knowledge regarding strategy suggests a hierarchy of metacognitive knowledge regarding usage of learning strategies.

A comparison of functional activation and connectivity of the cerebellum in adults and children during single word processing.

Meta-analyses on reading show cerebellar activation in adults, but not children, suggesting a possible age-dependent role of the cerebellum in reading. However, the few studies that compare adults and children during reading report mixed cerebellar activation results. Here, we studied (i) cerebellar activation during implicit word processing in adults and children and (ii) functional connectivity (FC) between the cerebellum and left cortical regions involved in reading. First, both groups activated bilateral cerebellum for word processing when compared to fixation, but not when compared to the active control. There were no differences between adults and children. Second, we found intrinsic FC between several cerebellar seed regions and cortical target regions in adults and children, as well as between-group differences. However, task-modulated FC specific to word processing revealed no within- nor between-group results. Together this study does not provide support for a role of the cerebellum in word processing at either age.

Students' 2018 PISA reading self-concept: Identifying predictors and examining model generalizability for emergent bilinguals.

Decades of research have indicated that reading self-concept is an important predictor of reading achievement. During this period, the population of emergent bilinguals has continued to increase within United States' schools. However, the existing literature has tended to examine native English speakers' and emergent bilinguals' reading self-concept in the aggregate, thereby potentially obfuscating the unique pathways through which reading self-concept predicts reading achievement. Furthermore, due to the overreliance of native English speakers in samples relating to theory development, researchers attempting to examine predictors of reading achievement may a priori select variables that are more aligned with native English speakers' experiences. To address this issue, we adopted Elastic Net, which is a theoretically agnostic methodology and machine learning approach to variable selection to identify the proximal and distal predictors of reading self-concept for the entire population; in our study, participants from the United States who participated in PISA 2018 served as the baseline group to determine significant predictors of reading self-concept with the intent of identifying potential new directions for future researchers. Based on Elastic Net analysis, 20 variables at the student level, three variables at the teacher level, and 12 variables at the school level were identified as the most salient predictors of reading self-concept. We then utilized a multilevel modeling approach to test model generalizability of the identified predictors of reading self-concept for emergent bilinguals and native English speakers. We disaggregated and compared findings for both emergent bilinguals and native English speakers. Our results indicate that although some predictors were important for both groups (e.g., perceived information and communications technologies competence), other predictors were not (e.g., competitiveness). Suggestions for future directions and implications of the present study are examined.
