Literacy acquisition influences children's rapid automatized naming

Impact of reading intervention on the phonological awareness of children with autism spectrum disorder: a systematic review and meta-analysis

PURPOSE

To review studies that have intervention in reading with impacts on phonological awareness in children with autism spectrum disorder.

RESEARCH STRATEGIES

Searches took place until February 2021 in Cochrane, Embase, ERIC (Education Resources Information Center), LILACS (Latin American and Caribbean Health Sciences Literature), PubMed/Medline, Scopus, Web of Science and gray literature databases.

SELECTION CRITERIA

The review included experimental studies with preschoolers and schoolchildren with ASD. Two independent reviewers selected the studies and, in case of disagreement, a third reviewer was consulted.

DATA ANALYSIS

Joanna Briggs Institute checklists were used for risk of bias. A random effects meta-analysis was performed and the certainty of the evidence was assessed using the GRADE tool.

RESULTS

Eight studies with some impact on phonological awareness were reviewed. The risk of bias was low and moderate. The certainty of the evidence was low for randomized trials and very low for non-randomised trials. Comparison of pre- and post-therapy on the Preschool Literacy Test (TOPEL) showed that children with ASD improved phonological awareness, with a mean difference between baseline and post-therapy of 6.21 (95% CI = 3.75-8.67; I2 = 0%).

CONCLUSION

Shared reading and software activities with words and phrases can alter phonological awareness. These results support further research with larger samples and a detailed description of the intervention to observe its effectiveness in phonological awareness.

Evaluation of the multiple-deficit hypothesis among dyslexic Arabic-speaking children

This study examined the multiple-deficit hypothesis among Arabic-speaking elementary school students. A total of 90 students, divided into three main groups based on their performance on an Arabic word-reading task: dyslexic (n = 30), regular age-matched (n = 30), and 3rd-grade regular students, who were matched to the dyslexic group in regard to their reading proficiency level (n = 30). Participants underwent a nine-domain Arabic reading experiment that measured accuracy and fluency to evaluate general reading proficiency. The performance of Arabic dyslexic students was significantly worse than age-matched controls, but similar to young matched controls based on the reading level of each cognitive task. Moreover, dyslexic students showed deficits in three or more cognitive functions, depending on severity. This study adds to the limited empirical research on the double-deficit hypothesis and its extension to the multiple-domain model among young Arabic students.

Dynamics of cognitive predictors during reading acquisition in a sample of children overrepresented for dyslexia risk

Literacy acquisition is a complex process with genetic and environmental factors influencing cognitive and neural processes associated with reading. Previous research identified factors that predict word reading fluency (WRF), including phonological awareness (PA), rapid automatized naming (RAN), and speech-in-noise perception (SPIN). Recent theoretical accounts suggest dynamic interactions between these factors and reading, but direct investigations of such dynamics are lacking. Here, we investigated the dynamic effect of phonological processing and speech perception on WRF. More specifically, we evaluated the dynamic influence of PA, RAN, and SPIN measured in kindergarten (the year prior to formal reading instruction), first grade (the first year of formal reading instruction) and second grade on WRF in second and third grade. We also assessed the effect of an indirect proxy of family risk for reading difficulties using a parental questionnaire (Adult Reading History Questionnaire, ARHQ). We applied path modeling in a longitudinal sample of 162 Dutch-speaking children of whom the majority was selected to have an increased family and/or cognitive risk for dyslexia. We showed that parental ARHQ had a significant effect on WRF, RAN and SPIN, but unexpectedly not on PA. We also found effects of RAN and PA directly on WRF that were limited to first and second grade respectively, in contrast to previous research reporting pre-reading PA effects and prolonged RAN effects throughout reading acquisition. Our study provides important new insights into early prediction of later word reading abilities and into the optimal time window to target a specific reading-related subskill during intervention.

Phonological awareness and rapid automatized naming as predictors of early literacy skills among children with mild to borderline intellectual functioning

The aim was to investigate the predicting role of phonological awareness (PA) and rapid automatized naming (RAN) on early literacy skills (e.g., word reading [WR] and spelling [SP]) among children with mild to borderline intellectual functioning. A total of 68 children in inclusive schools in grades 1 and 2, from 12 primary schools from Makka, classified as having intellectual disabilities (ID) of unspecified origin were chosen to participate in this study. Measures of PA and RAN were correlated with measures of WR and SP in children with mild to borderline intellectual functioning. This study advanced knowledge about the predictors (PA and RAN) of early literacy skills (WR and SP) among children with mild to borderline intellectual functioning.

Effects of adult education on cognitive function and risk of dementia in older adults: a longitudinal analysis

Introduction

Mid/late-life cognitive activities are associated with a lower rate of subsequent cognitive decline and lower subsequent dementia risk over time.

Methods

In this study, we investigated the association between adult education class participation and subsequent cognitive decline and dementia risk over time after adjusting for baseline cognitive function and genetic risk of dementia, correcting for several potential confounding variables, using a large prospective cohort data of participants from the UK Biobank study followed from 2006 to 2010.

Results

The results revealed that participation in adult education classes at baseline was associated with greater subsequent retention of fluid intelligence score. Cox proportional hazard models revealed that subjects who participated in adult education classes showed a significantly lower risk of incident dementia 5 years after baseline compared with those that did not at baseline.

Discussion

In this study, we show that participation in adult education classes preceded greater retention of subsequent fluid intelligence and a lower risk of developing dementia after 5 years: this association did not change after adjusting for cognitive function at baseline or genetic predisposition to dementia. Accordingly, participation in such classes could reduce the risk of developing dementia.

Challenging the stability of RAN development: Acknowledging PA and Gf in relation to reading

This study had two overriding goals, (1) examine the stability of rapid automatized naming (RAN) in predicting reading achievement while taking into account two other frequently studied constructs, phonological awareness and fluid intelligence (Gf) and (2) examine the predictive power of RAN measured at age 4 on reading ability. The stable pattern of RAN development found in a previously reported growth model was challenged by relating phonological awareness and Gf to the model. Children (N = 364) were followed from age 4 to age 10. At age 4, Gf related strongly to phonological awareness, which in turn related strongly to RAN. The relations between the RAN measures over time was largely unaffected by the inclusion of Gf and phonological awareness. RAN, Gf and phonological awareness at age 4 independently predicted latent factors reflecting reading-related abilities in grade 1 and grade 4. However, when scrutinizing type of reading measure in grade 4, Gf, phonological awareness and RAN at age 4 predicted both spelling and reading fluency, whereas RAN in grade 2 did not predict spelling but was the strongest predictor of reading fluency.

The multiple-level framework of developmental dyslexia: the long trace from a neurodevelopmental deficit to an impaired cultural technique

Developmental dyslexia is a neurodevelopmental disorder characterized by an unexpected impairment in literacy acquisition leading to specific poor academic achievement and possible secondary symptoms. The multi-level framework of developmental dyslexia considers five levels of a causal pathway on which a given genotype is expressed and hierarchically transmitted from one level to the next under the increasing influence of individual learning-relevant traits and environmental factors moderated by cultural conditions. These levels are the neurobiological, the information processing and the skill level (prerequisites and acquisition of literacy skills), the academic achievement level and the level of secondary effects. Various risk factors are present at each level within the assumed causal pathway and can increase the likelihood of exhibiting developmental dyslexia. Transition from one level to the next is neither unidirectional nor inevitable. This fact has direct implications for prevention and intervention which can mitigate transitions from one level to the next. In this paper, various evidence-based theories and findings regarding deficits at different levels are placed in the proposed framework. In addition, the moderating effect of cultural impact at and between information processing and skill levels are further elaborated based on a review of findings regarding influences of different writing systems and orthographies. These differences impose culture-specific demands for literacy-specific cognitive procedures, influencing both literacy acquisition and the manifestation of developmental dyslexia.

The Comprehensive Test of Phonological Processing, Second Edition: Measurement Invariance for Dual Language Learners

The Comprehensive Test of Phonological Processing, 2nd Edition (CTOPP-2; Wagner et al., 2013) is commonly used in k-12 public schools to assess basic cognitive processing skills foundational for reading achievement. Psychometric support for its use with dual language learners (DLLs), a group representing over 10% of the school-aged population in the United States, is critical. This study tested the metric and scaler invariance of CTOPP-2 scores among school-aged children ( n = 242; 41.3% Spanish-speaking DLL). Results indicate that the CTOPP-2’s three-factor (i.e., Phonological Awareness, Phonological Memory, and Rapid Automatic Naming) measurement structure displays metric and scalar invariance for DLLs. Model fit was improved when the Phonological Awareness and Phonological Memory factors were combined. Implications for future research and the practice of psychoeducational diagnostic assessment with DLLs are discussed.

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.

Phonological awareness, rapid automatized naming, and reading of functionally illiterate adults

PURPOSE

The study's purpose is to describe the cognitive profile of a sample of functionally illiterate individuals in reading, phonological awareness (PA) and rapid automatized naming (RAN), as well as to correlate the performance of these tasks. Moreover, it sought to understand how the performances in PA and RAN predict results in reading of words and pseudowords.

METHODS

23 functionally illiterate adults were assessed for intelligence, reading, PA and RAN tasks.

RESULTS

Participants showed difficulties in PA, performing poorly in tasks involving phoneme analysis and manipulation. In RAN, they found it easier to name alphanumeric items. Regarding reading, they presented difficulties in phonological processing, with errors caused by phonological exchange. Correlation analyses indicated that reading presented higher correlations with RAN than PA. Finally, a regression analysis indicated that performance in RAN can account for more than half of participants' reading results.

CONCLUSION

In general, the profile of functionally illiterate adults presents impairment in the abilities assessed that are more evident in PA at phoneme levels as well as in naming of non-alphanumerical items. Moreover, the results in RAN explain those in word and pseudowords reading better than the results in PA.

Dyslexia in a consistent orthography: Evidence from reading-level match design

Studies in consistent orthographies using reading-level (RL) match design have produced conflicting results, possibly because of problems with general ability and RL matching in many studies. We matched the participants on both verbal and nonverbal ability and on reading tasks with no ceiling effects and compared the performance of Grades 4 and 6 Greek-speaking children with dyslexia to those of chronological age (CA) and RL matched control groups across a variety of tasks associated with dyslexia (phonological awareness, rapid naming, phonological memory, and orthographic processing). The results showed that although both Grade 4 and Grade 6 dyslexics performed poorer than the CA groups in most tasks, they did not perform poorer than the RL group in any of the tasks included. We conclude with a discussion of the theoretical ramifications of the results and the appropriateness of the RL match design in studying dyslexia in consistent orthographies.

Stable auditory processing underlies phonological awareness in typically developing preschoolers

Sound processing is an important scaffold for early language acquisition. Here we investigate its relationship to three components of phonological processing in young children (∼age 3): Phonological Awareness (PA), Phonological Memory (PM), and Rapid Automatized Naming (RAN). While PA is believed to hinge upon consistency of sound processing to distinguish and manipulate word features, PM relies on an internal store of the sounds of language and RAN relies on fluid production of those sounds. Given the previously demonstrated link between PA and the auditory system, we hypothesized that only this component would be associated with auditory neural stability. Moreover, we expected relationships to manifest at early ages because additional factors may temper the association in older children. We measured across-trial stability of the frequency-following response, PA, PM, and RAN longitudinally in twenty-seven children. Auditory neural stability at age ∼3 years exclusively predicts PA, but this relationship vanishes in older children.

Training RAN or reading? A telerehabilitation study on developmental dyslexia

Rehabilitation procedures recommended for developmental dyslexia (DD) are still not fully defined, and only few studies directly compare different types of training. This study compared a training (Reading Trainer) working on the reading impairment with one (Run the RAN) working on the rapid automatized naming (RAN) impairment, one of the main cognitive deficits associated with DD. Two groups of DD children (N = 45) equivalent for age, sex, full IQ, and reading speed were trained either by Reading Trainer (n = 21) or by Run the RAN (n = 24); both trainings required an intensive home exercise, lasting 3 months. Both trainings showed significant improvements in reading speed and accuracy of passages and words. Bypassing the use of alphanumeric stimuli, but empowering the cognitive processes underlying reading, training RAN may be a valid tool in children with reading difficulties opening new perspectives for children with severe impairments or, even, at risk of reading difficulties.

Current profiles and early predictors of reading skills in school-age children with autism spectrum disorders: A longitudinal, retrospective population study

This study explores current reading profiles and concurrent and early predictors of reading in children with autism spectrum disorder. Before the age of 3 years, the study cohort underwent a neurodevelopmental assessment following identification in a population-based autism screening. At age 8 years, reading, language and cognition were assessed. Approximately half of the sample ( n = 25) were ‘poor readers’ at age 8 years, meaning that they scored below the normal range on tests of single word reading and reading comprehension. And 18 were ‘skilled readers’ performing above cut-offs. The final subgroup ( n = 10) presented with a ‘hyperlexic/poor comprehenders’ profile of normal word reading, but poor reading comprehension. The ‘poor readers’ scored low on all assessments, as well as showing more severe autistic behaviours than ‘skilled readers’. Group differences between ‘skilled readers’ and ‘hyperlexics/poor comprehenders’ were more subtle: these subgroups did not differ on autistic severity, phonological processing or non-verbal intelligence quotient, but the ‘hyperlexics/poor comprehenders’ scored significantly lower on tests of oral language. When data from age 3 were considered, no differences were seen between the subgroups in social skills, autistic severity or intelligence quotient. Importantly, however, it was possible to identify oral language weaknesses in those that 5 years later presented as ‘poor readers’ or ‘hyperlexics’.

Auditive training effects from a dichotic listening app in children with dyslexia

Dichotic listening (DL) taps information on the brain's language laterality, processing, and attention. Research has shown that DL responses in dyslexia deviate from the typical pattern. Here, effects of DL training and its correspondence to rapid naming (RAN) and digit span (DS) in typical children and children with dyslexia were assessed. Three groups of third graders participated: two training groups, control training (CT) and dyslexia training (DT), and a control group that received no training (control no training, CnT). All took part in testing pretraining and posttraining. DL measures were on laterality, response scores, and attention. The three groups showed different response patterns: minor changes in CnT, change in all measures in CT, and some changes in DT. RAN and DS scores correlated significantly with some of the DL measures, especially with the attention scores. Our findings support arguments that brain architecture for language in dyslexia is lateralised in the same way as in children without dyslexia. However, the ability to modulate attention during DL is weaker in dyslexia than in typically developing children. A training-induced normalisation of lateralisation was observed in free recall in the dyslexia group, which suggests that DL training may be a promising intervention approach.
