Auditory attention influences trajectories of symbol–speech sound learning in children with and without dyslexia

The acquisition of letter–speech sound correspondences is a fundamental process underlying reading development, one that could be influenced by several linguistic and domain-general cognitive factors. In the current study, we mimicked the first steps of this process by examining behavioral trajectories of audiovisual associative learning in 110 7- to 12-year-old children with and without dyslexia. Children were asked to learn the associations between eight novel symbols and native speech sounds in a brief training and subsequently read words and pseudowords written in the artificial orthography. We then investigated the influence of auditory attention as one of the putative domain-general factors influencing associative learning. To this aim, we assessed children with experimental measures of auditory sustained selective attention and interference control. Our results showed shallower learning trajectories in children with dyslexia, especially during the later phases of the training blocks. Despite this, children with dyslexia performed similarly to typical readers on the post-training reading tests using the artificial orthography. Better auditory sustained selective attention and interference control skills predicted greater response accuracy during training. Sustained selective attention was also associated with the ability to apply these novel correspondences in the reading tests. Although this result has the limitations of a correlational design, it denotes that poor attentional skills may constitute a risk during the early stages of reading acquisition, when children start to learn letter–speech sound associations. Importantly, our findings underscore the importance of examining dynamics of learning in reading acquisition as well as individual differences in more domain-general attentional factors.

Can an Online Reading Camp Teach 5-Year-Old Children to Read?

Literacy is an essential skill. Learning to read is a requirement for becoming a self-providing human being. However, while spoken language is acquired naturally with exposure to language without explicit instruction, reading and writing need to be taught explicitly. Decades of research have shown that well-structured teaching of phonological awareness, letter knowledge, and letter-to-sound mapping is crucial in building solid foundations for the acquisition of reading. During the COVID-19 pandemic, children worldwide did not have access to consistent and structured teaching and are, as a consequence, predicted to be behind in the development of their reading skills. Subsequent evidence confirms this prediction. With the best evidence-based practice in mind, we developed an online version of a well-structured early literacy training program (Reading Camp) for 5-year-old children. This 2-week online Reading Camp program is designed for pre-K children. It incorporates critical components of the fundamental skills essential to learning to read and is taught online in an interactive, multi-sensory, and peer-learning environment. We measure the participants’ literacy skills and other related skills before and after participating in the online Reading Camp and compare the results to no-treatment controls. Results show that children who participated in the online Reading Camp improved significantly on all parameters in relation to controls. Our results demonstrate that a well-structured evidence-based reading instruction program, even if online and short-term, benefits 5-year-old children in learning to read. With the potential to scale up this online program, the evidence presented here, alongside previous evidence for the efficacy of the in-person program, indicates that the online Reading Camp program is effective and can be used to tackle a variety of questions regarding structural and functional plasticity in the early stages of reading acquisition.

Pausing and breathing while reading aloud: development from 2nd to 7th grade in French speaking children

Pauses when reading aloud play an essential role in reading and listening comprehension (for a review: Godde et al., 2020). Among the various types of pauses, breathing pauses during oral reading are particularly important. Their placement, frequency and duration tell us about breath and voice coordination as well as articulatory planning. These skills that develop over time, from the early stages of reading acquisition to skilled reading levels, are under-researched. The present study aims to describe how children develop the ability to use pauses during oral reading by comparing young French speaking readers ranging from second to seventh graders to adults. Voice and breathing patterns of 295 children and 20 adults were recorded during oral reading. Specific attention was given to the frequency, duration and placement of breathing pauses and inhalation to phonation delay. Our results revealed that the youngest students performed more ungrammatical pauses, breathed more frequently and produced longer inhalation to phonation delays. Children older than grade 4 were visibly more proficient at planning their pauses, particularly their breathing pauses, and tended to rely more on punctuation. Finally, pause planning observed for the grade 7 students was almost at adult level. This developmental study suggests that children’s acquisition of pausing patterns during oral reading occurs gradually between the 2nd and 7th grades and highlights the important role of punctuation in planning breathing pauses and syntactic-prosodic breaks. Based on our results, we discuss the relation between pauses, decoding and expressivity, and develop didactic proposals for developing oral reading prosody.

Decoding the role of the cerebellum in the early stages of reading acquisition

Numerous studies have consistently reported functional activation of the cerebellum during reading tasks, especially in the right cerebellar hemisphere. However, it remains unclear whether this region is also involved in reading during the earliest stages of reading acquisition. Here, we investigated whether and how the cerebellum contributes to reading acquisition. We tested 80 5-6-year-old kindergarteners, who performed a visual word matching task during which functional MRI (fMRI) data were collected. We found that bilateral cerebellar hemispheres were significantly activated during visual word processing. Moreover, activation of left cerebellar lobule VII extending to lobule VIII negatively and significantly correlated with current reading ability, whereas activation of right cerebellar lobule VII extending to lobule VIII significantly and positively correlated with future reading ability. Functional decoding via functional connectivity patterns further revealed that left and right cerebellar lobules connected with different cerebral cortex regions. Our results suggest a division of labor between the left and right cerebellar lobules in beginning readers.

Oral reading fluency, reading motivation and reading comprehension among second graders

The relationships between oral reading fluency, reading motivation and reading comprehension were examined at the beginning and the end of second grade among 121 Hebrew speaking students. The contribution of oral reading fluency and three sub-factors of motivation—self-concept as a reader, value attached to reading and literacy outloud (social interactions about literacy)—at the beginning of the school year to reading comprehension at the end of the year was also examined. Results indicate that all oral reading fluency measures and all motivational sub-factors were significantly correlated with reading comprehension at the end of second grade. In addition, positive change in self-concept as a reader along the school year was related to improvement in reading achievement. Finally, text rate and self-concept as a reader at the beginning of second grade together predicted 28% of the variance in reading comprehension at the end of second grade. The results support the notion that the cognitive approach to reading cannot explain all the variance in reading comprehension and emphasize the necessity of including motivational factors in the language arts curriculum in the early stages of reading acquisition.

Letter and Speech Sound Association in Emerging Readers With Familial Risk of Dyslexia.

In alphabetic scripts, learning letter-sound (LS) association (i.e., letter knowledge) is a strong predictor of later reading skills. LS integration is related to left superior temporal cortex (STC) activity and its disruption was previously observed in dyslexia (DYS). Whether disruption in LS association is a cause of reading impairment or a consequence of decreased exposure to print remains unclear. Using fMRI, we compared activation for letters, speech sounds and LS association in emerging readers with (FHD+, N = 50) and without (FHD−, N = 35) familial history of DYS, out of whom 17 developed DYS 2 years later. Despite having similar reading skills, FHD+ and FHD− groups showed opposite pattern of activation in left STC: In FHD− children activation was higher for incongruent compared to congruent, whereas in FHD+ it was higher for congruent LS pairs. Higher activation to congruent LS pairs was also characteristic of future DYS. The magnitude of incongruency effect in left STC was positively related to early reading skills, but only in FHD− children and (retrospectively) in typical readers. We show that alterations in brain activity during LS association can be detected at very early stages of reading acquisition, suggesting their causal involvement in later reading impairments. Increased response of left STC to incongruent LS pairs in FHD− group might reflect an early stage of automatizing LS associations, where the brain responds actively to conflicting pairs. The absence of such response in FHD+ children could lead to failures in suppressing incongruent information during reading acquisition, which could result in future reading problems.

The Relationship between White Matter and Reading Acquisition, Refinement and Maintenance

Reading requires efficient communication between brain regions that are situated all over the cortex. These brain areas are structurally connected by white-matter pathways that develop over the period of reading acquisition. Here, we conducted a cross-sectional study to assess the relationship between white-matter tracts and reading performance across the lifespan. Methods: Behavioral (reading performance) and neuroimaging (diffusion tensor imaging [DTI]) data were collected from participants aged 3–21 years as a part of the multi-site project called the pediatric imaging neurocognition genetics study. DTI measures (fractional anisotropy [FA], mean diffusivity, radial diffusivity and axial diffusivity) of bilateral dorsal tracts (arcuate fasciculus, superior longitudinal fasciculus, and posterior superior longitudinal fasciculus) and ventral tracts (uncinate fasciculus, inferior fronto-occipital fasciculus, and inferior longitudinal fasciculus) were extracted. Reading performance was calculated as the number of items correctly read (words for older children and letters in the case of young children). Correlational and regression analyses were conducted between the DTI measures and reading scores. Results: During the early stages of reading acquisition (ages 3–6), the dorsal tracts were positively related to reading performance (as FA goes up, reading performance goes up). For ages 6–10, the dorsal tracts remain positively associated with reading performance and a relationship between ventral tracts and reading performance emerges. From the age of 10 onwards, the dorsal tracts no longer correlate with reading performance, and a brain-behavior relationship in the right ventral tracts begins to shift, whereby higher FA is associated with lower reading performance. In addition to the involvement of left hemispheric tracts, this study revealed the initial engagement of right hemispheric tracts during the early stages of reading acquisition. Conclusion: We discuss these different associations of white-matter tracts with reading during development in the context of the biological processes model of myelination and pruning.

What Is the Influence of Morphological Knowledge in the Early Stages of Reading Acquisition Among Low SES Children? A Graphical Modeling Approach.

Children from low-SES families are known to show delays in aspects of language development which underpin reading acquisition such as vocabulary and listening comprehension. Research on the development of morphological skills in this group is scarce, and no studies exist in French. The present study investigated the involvement of morphological knowledge in the very early stages of reading acquisition (decoding), before reading comprehension can be reliably assessed. We assessed listening comprehension, receptive vocabulary, phoneme awareness, morphological awareness as well as decoding, word reading and non-verbal IQ in 703 French first-graders from low-SES families after 3 months of formal schooling (November). Awareness of derivational morphology was assessed using three oral tasks: Relationship Judgment (e.g., do these words belong to the same family or not? heat-heater … ham-hammer); Lexical Sentence Completion [e.g., Someone who runs is a …? (runner)]; and Non-lexical Sentence Completion [e.g., Someone who lums is a…? (lummer)]. The tasks differ on implicit/explicit demands and also tap different kinds of morphological knowledge. The Judgement task measures the phonological and semantic properties of the morphological relationship and the Sentence Completion tasks measure knowledge of morphological production rules. Data were processed using a graphical modeling approach which offers key information about how skills known to be involved in learning to read are organized in memory. This modeling approach was therefore useful in revealing a potential network which expresses the conditional dependence structure between skills, after which recursive structural equation modeling was applied to test specific hypotheses. Six main conclusions can be drawn from these analyses about low SES reading acquisition: (1) listening comprehension is at the heart of the reading acquisition process; (2) word reading depends directly on phonemic awareness and indirectly on listening comprehension; (3) decoding depends on word reading; (4) Morphological awareness and vocabulary have an indirect influence on word reading via both listening comprehension and phoneme awareness; (5) the components of morphological awareness assessed by our tasks have independent relationships with listening comprehension; and (6) neither phonemic nor morphological awareness influence vocabulary directly. The implications of these results with regard to early reading acquisition among low SES groups are discussed.

Does the late positive component reflect successful reading acquisition? A longitudinal ERP study.

Developmental dyslexia is a reading disorder that is associated with deficits in phonological processing, where the exact neural basis for those processing deficits remains unclear. In particular, disagreement exists whether degraded phonological representations or an impaired access to the phonological representations causes these deficits. To investigate this question and to trace changes in neurophysiology during the process of reading acquisition, we designed a longitudinal study with event related potentials (ERPs) in children between kindergarten and second grade. We used an explicit word processing task to elicit the late positive component (LPC), which has been shown to reflect phonological processing. A brain-wide analysis of the LPC with an electrode-wise application of mixed effects models showed significantly attenuated amplitudes in the left temporo-parietal region in dyslexic children. Since these differences were only present in the word and not in the picture (i.e. control) condition, the attenuated amplitudes might reflect impaired access to the phonological representations of words. This was further confirmed by the longitudinal development, which showed a rapid increase in amplitude at the beginning of reading instruction and a decrease with continuing automatization, possibly pointing to a progression from grapheme-phoneme parsing to whole word reading. Our longitudinal study provides the first evidence that it is possible to detect neurophysiological differences in the LPC between children with dyslexia and control children in both preliterate and very early stages of reading acquisition, providing new insights about the neurophysiological development and a potential marker of later reading problems.

Investigating developmental trajectories of morphemes as reading units in German.

The developmental trajectory of the use of morphemes is still unclear. We investigated the emergence of morphological effects on visual word recognition in German in a large sample across the complete course of reading acquisition in elementary school. To this end, we analyzed lexical decision data on a total of 1,152 words and pseudowords from a large cross-sectional sample of German children from the beginning of Grade 2 through 6, and a group of adults. We expand earlier evidence by (a) explicitly investigating processing differences between compounds, prefixes and suffixes, (b) taking into account vocabulary knowledge as an indicator for interindividual differences. Results imply that readers of German are sensitive to morphology in very early stages of reading acquisition with trajectories depending on morphological type and vocabulary knowledge. Facilitation from compound structure comes early in development, followed by facilitation from suffixes and prefixes later on in development. This indicates that stems and different types of affixes involve distinct processing mechanisms in beginning readers. Furthermore, children with higher vocabulary knowledge benefit earlier in development and to a greater extent from morphology. Our results specify the development and functional role of morphemes as reading units. (PsycINFO Database Record

Syllabic Schemes and Knowledge of the Alphabet in Reading Acquisition: Onset or Nucleus Variation

<p class="apa">Although there is a growing consensus that, in reading acquisition, it is essential to provide children with learning activities that promote the development of reading cognitive schemes, particularly intra-syllabic related patterns, there is no agreement on which kind of syllabic schemes should be worked out in the first place. The main aim of the present study is to analyse the readings of preschool Spanish-speaking children showing the development of syllabic schemes in the early stages of reading acquisition. Basically, we analyse their responses in relation to their previous knowledge of Spanish grapheme-phoneme correspondences (GPCs) or alphabet knowledge. Our results show that children’s recognition and construction of syllabic schemes, from the very first steps in preschool reading acquisition programmes, is facilitated by reading activities presenting shell-nucleus syllabic patterns, for which the only requirement, although not indispensable, is to know the five or six Spanish vowel GPCs. This kind of activity seems to be more adequate than reading drills involving onset-rhyme syllabic analogies that require previous knowledge of consonant GPCs. The conclusion we have reached is that the development of onset-rhyme syllabic reading schemes shows a stronger relation to alphabet knowledge that shell-nucleus syllabic reading schemes, at least in the early stages of reading learning.</p>

Avaliação das habilidades preditoras do sucesso de leitura em crianças de 1º e 2º anos do ensino fundamental

OBJETIVO: estudar o desempenho de escolares de 1º e 2º anos do Ensino Fundamental (EF), em tarefas que avaliam habilidades e competências consideradas preditoras do sucesso do aprendizado da leitura e escrita. MÉTODOS: 73 crianças, entre seis e oito anos de idade, estudantes do 1º e 2º anos do EF de escola da rede pública de ensino da cidade de São Paulo, foram avaliadas por meio da aplicação do Instrumento de Avaliação da Leitura Inicial, composto por 20 tarefas envolvendo as habilidades e competências de linguagem oral, conhecimento sobre escrita, processamento fonológico, compreensão e leitura e escrita. RESULTADO: foi possível constatar que alguns escolares, tanto de 1º como de 2º ano, obtiveram desempenho inferior à média de seus grupos nas habilidades consideradas preditoras para o sucesso da leitura. Esse desempenho foi identificado a partir da porcentagem total de acertos obtida no Instrumento e a consequente classificação dos escolares em intervalos de percentis. Os grupos escolares diferenciaram-se apenas nas tarefas relacionadas às habilidades do processamento fonológico e nas competências de leitura e escrita, com melhor desempenho para os escolares do 2º ano, nas seguintes provas: (a) leitura de palavras; (b) leitura de pseudopalavras; (c) ditado de palavras; (d) ditado de pseudopalavras; (e) produção de rimas; (f) compreensão de leitura. CONCLUSÃO: a escolarização influenciou o desempenho em habilidades de processamento fonológico e competências de leitura e escrita. Habilidades de processamento fonológico e de conhecimento de escrita mostraram-se correlacionadas ao desempenho em codificação e decodificação, envolvidas na escrita e leitura de itens isolados.

Interpreting the Relationships Among Prosody, Automaticity, Accuracy, and Silent Reading Comprehension in Secondary Students

Although identified as a critical component of proficient reading in the primary grades, reading fluency (word recognition accuracy, automaticity, and prosody) is often viewed as less important beyond the early stages of reading acquisition. In the present study, 108 ninth-grade students were assessed to explore the relationships among word recognition accuracy, automaticity, prosody, and vocabulary with silent reading comprehension. Results found large correlations among the variables while regression analysis revealed that accuracy, prosody, and vocabulary explained from 50.1% to 52.7% of the variance in silent reading comprehension. Of note were the findings that word recognition automaticity did not contribute to silent reading comprehension although prosody was found to act as a partial mediator between automaticity and comprehension. Accuracy, automaticity, and prosody were found to form a highly reliable scale reflecting oral reading fluency. These findings contribute to the growing body of evidence suggesting that secondary students exhibiting appropriate prosody experience advantages in comprehension processing. The tandem theory of reading is introduced to explain the relationship between automaticity and comprehension.

Developmental changes in the role of different metalinguistic awareness skills in Chinese reading acquisition from preschool to third grade.

The present study investigated the relationship between Chinese reading skills and metalinguistic awareness skills such as phonological, morphological, and orthographic awareness for 101 Preschool, 94 Grade-1, 98 Grade-2, and 98 Grade-3 children from two primary schools in Mainland China. The aim of the study was to examine how each of these metalinguistic awareness skills would exert their influence on the success of reading in Chinese with age. The results showed that all three metalinguistic awareness skills significantly predicted reading success. It further revealed that orthographic awareness played a dominant role in the early stages of reading acquisition, and its influence decreased with age, while the opposite was true for the contribution of morphological awareness. The results were in stark contrast with studies in English, where phonological awareness is typically shown as the single most potent metalinguistic awareness factor in literacy acquisition. In order to account for the current data, a three-stage model of reading acquisition in Chinese is discussed.

Lexical effects in word naming in spanish children.

Reading strategies depend on the consistency of the orthographic system. Recently the use of lexical strategies at early stages of reading acquisition has been shown even in transparent orthographies. The aim of this study was to know how different lexical and sublexical variables affect the reaction times (RTs) and articulation times (ATs) in word reading in Spanish children. A group of 46 children of typical reading level in the second and fourth grades of primary school were asked to read aloud 100 words presented on a computer screen. The stimuli were morphologically simple nouns with different ranges of length, frequency, imageability, orthographic neighbors and age of acquisition (AoA). Reading and articulation time were measured. Differences between means of the second and the fourth grade were seen in RTs (p < .001; Cohens' d = 1.41) and ATs (p < 001;Cohen's d = 1.41) in a t-test. Analyses of mixed-effects revealed that word length, a sublexical variable, and frequency and AoA, lexical variables, affected both grades, mainly on the RTs. The presence of lexical variables reducing RTs and ATs in second grade suggests that lexical reading is present from very early stages in Spanish children.

Turning visual shapes into sounds: Early stages of reading acquisition revealed in the ventral occipitotemporal cortex

The exact role of the left ventral occipitotemporal cortex (VOTC) during the initial stages of reading acquisition is a hotly debated issue, especially regarding the comparative effect of learning on early stimulus-dependent vs. later task-dependent processes. We show that this controversy can be solved with high-temporal resolution intracerebral EEG recordings of the VOTC. We measured High-Frequency Activity (50–150Hz) as a proxy of population-level spiking activity while participants learned Japanese Katakana symbols, and found that learning primarily affects top-down/task-dependent neural processing, after a few minutes only. In contrast, adaptation of early bottom-up/stimulus-dependent processing takes several days to adapt and provides the basis for fluent reading. Such evidence that two consecutive stages of neural processing, stimulus- and task-dependent are differentially affected by learning, can reconcile seemingly opposite hypotheses on the role of the VOTC during reading acquisition.

Current themes in neuroimaging studies of reading

This editorial provides a summary of the highlights from 11 new papers that have been published in a special issue of Brain and Language on the neurobiology of reading. The topics investigate reading mechanisms in both adults and children. Several of the findings illustrate how responses in the left ventral occipito-temporal cortex, and other reading areas, change with learning, expertise and the task: In the early stages of reading acquisition, learning/expertise increases activation in reading areas as well as in an attentionally-controlled, learning circuit. In later stages, expertise and efficiency decrease activation within the reading network and increase anatomical connectivity. Special interest is given to a white matter tract (the vertical occipital fasciculus) that projects dorsally from the left occipito-temporal cortex to the posterior parietal lobe. This observation fits with a magnetoencephalography study showing how activity in the angular gyrus is influenced by early occipito-temporal activity; with angular gyrus activity contributing to inferior frontal activity. Overall, the papers within the special issue illustrate the wide range of different techniques that can be used to reveal the functional anatomy of reading and the time course of activity within the different reading pathways.

What are the underlying skills of silent reading acquisition? A developmental study from kindergarten to the 2nd grade

Research on reading acquisition and on the processes underlying it usually examined reading orally, while silent reading, which is the more common mode of reading, has been rather neglected. As accumulated data suggests that these two modes of reading only partially overlap, our understanding of the natural mode of reading may still be limited. The present study was set out to explore the underlying skills of reading acquisition examined using silent measures of reading. To this end, children acquiring reading of the phonologically transparent vowelized Hebrew orthography were followed from kindergarten to the 2nd grade. The relations between a range of verbal and visual-spatial skills with measures of silent reading were tested. Phonological awareness, RAN and vocabulary explained a significant amount of variance in fluency in word recognition and in fluency in decoding of pseudo-homophones, while visual speed of processing of numeric symbols explained a notable amount of variance in fluency in word recognition only. Phonological awareness, morphological awareness and phonological working memory were the main skills explaining the variance in reading comprehension. The relations of these skills with the quality of oral reading have been widely established in the reading literature. Furthermore, a similar developmental picture was obtained in the relations between some of these skills and silent reading, as was found with oral reading. Therefore the role of these skills in reading may not be restricted to a certain mode of reading. Also consistent with findings on oral reading, the role of the visual non-orthographic skills in the measures of silent reading was insignificant to very small. Together these results imply that the processes underlying measures of silent reading are not substantially different from the ones underlying measures of oral reading, at least not at the early stages of reading acquisition of a transparent orthography.

Rapid Automatized Naming and Lexical Decision in Children from an Electrophysiological Perspective

Rapid Automatized Naming (RAN) deficits have been associated with less developed orthographic abilities that may affect lexical decisions. The effects of Spanish-speaking children's RAN performance on lexical decisions were evaluated by analyzing ERP and behavioral measures. Based upon their naming speed in four RAN tasks, 28 normal IQ, right-handed, 7-year-old children were selected and divided uniformly into two groups: average-naming (AN), and slow-naming (SN). ERPs were obtained during a lexical decision task consisting of 100 strings of four sequentially-presented letters that completed words (50 trials) or pseudowords (also 50 trials). The SN group showed major reading difficulties when compared to the AN group, as well as a significantly lower number of correct responses and slower reaction times in the lexical task. Two main ERP components were observed: parietal N320, interpreted as analogous to N170/N200; and a subsequent P3-like component (P500) with a higher amplitude for pseudowords, which probably reflects higher cognitive demands. Better reading comprehension and fewer misread pseudowords correlated with minor N320 latencies, while lower N320 amplitudes for words correlated with faster reading speeds, lower naming times and fewer errors while reading a text. The present results suggest that naming speed and ERP seem to be valuable in distinguishing early orthographic stored code retrieval abilities through a lexical decision task. Moreover, RAN and ERP emerge as accurate tools for evaluating reading processes in the early stages of reading acquisition.

Brain activation profiles during the early stages of reading acquisition.

In the present study, we demonstrate for the first time the presence of an aberrant brain mechanism for reading in children who have just started acquiring reading skills. Children who, at the end of kindergarten, are found to be at risk for developing reading problems display markedly different activation profiles than children who have, at this stage, already mastered important prereading skills. This aberrant profile is characterized by the lack of engagement of the left-hemisphere superior temporal region, an area normally involved in converting print into sound, and an increase in activation in the corresponding right-hemisphere region. This finding is consistent with current cognitive models of reading acquisition and dyslexia, pointing to the critical role of phonologic awareness skills in learning to read.
