Phonological awareness mediates the relationship between DCDC2 and reading performance with home environment

Proficient reading requires critical phonological processing skill that interacts with both genetic and environmental factors. However, the precise nature of the relationships between phonological processing and genetic and environmental factors are poorly understood. We analyzed data from the Genes, Reading and Dyslexia (GRaD) Study on 1419 children ages 8–15 years from African-American and Hispanic-American family backgrounds living in North America. The analyses showed that phonological awareness mediated the relationship between DCDC2-READ1 and reading outcomes when parental education and socioeconomic status was low. The association between READ1 and reading performance is complex, whereby mediation by phonological awareness was significantly moderated by both parental education and socioeconomic status. These results show the importance of home environment and phonological skills when determining associations between READ1 and reading outcomes. This will be an important consideration in the development of genetic screening for risk of reading disability.

The Role of Second Language Reading Proficiency in Moderating Second Language Word Recognition

Drawing upon the division of labor between orthographic and phonological information, this study investigated whether and how L2 reading proficiency moderates learners’ reliance on phonological and orthographic information in retrieving word meanings. A total of 136 Chinese collegiate students who learned English as a foreign language (EFL) completed English reading proficiency tests and were divided into higher and lower reading proficiency groups using an extreme-group approach. Behavioral tasks were used to measure the participants’ sensitivity to and processing skills of orthographic and phonological information. The analysis showed that the reliance on phonological and orthographic information differed significantly across L2 reading proficiency groups: The higher reading proficiency group was sensitive to both phonological and orthographic information within words, while the lower reading proficiency group was only sensitive to orthographic information; only orthographic processing skills significantly contributed to the word meaning retrieval of individuals in the higher reading proficiency group, while phonological processing skills were the only predictor for the lower reading proficiency group. These results suggest that the use of phonological and orthographic information vary as a function of L2 learners’ English reading proficiency. Implications regarding the changing patterns of L1 influences and the language-universal and language-specific aspects of word recognition were discussed.

The Arabic-Phonological Processing Test (A-PPT): development, validity, and reliability

ABSTRACT This study introduces the Arabic-Phonological Processing Test (A-PPT) and conducts a thorough assessment of its validity and reliability. The A-PPT functions as a tool for evaluating three fundamental phonological processing skills: phonological awareness, phonological memory, and rapid naming. It aligns with the theoretical framework and administration protocols of the Comprehensive Test of Phonological Processing (CTOPP). The A-PPT comprises 10 distinct subtests and features a total of 325 items, all presented in standard Arabic and progressively increase in difficulty. Our research includes 550 Jordanian children aged 4–8, including both kindergarten and primary grades in elementary school. The A-PPT underwent meticulous piloting and comprehensive testing for validation and reliability. Face validity, determined through content expertise, yielded favorable outcomes. Internal consistency reliability, assessed via Cronbach’s alpha, demonstrated acceptable consistency levels for untimed subscales, ranging from .61 to .964, with the lowest alpha value observed in the 7–8-year-old age group, particularly for the Memory of Digits subtest. In contrast, timed subtests exhibited reliability coefficients between 0.817 and 0.916. Exploratory factor analysis revealed three interrelated subscales explaining 76% of the variance. Further evaluations of test-retest and inter-rater reliability demonstrated moderate to excellent correlation coefficients, with intraclass correlation coefficients ranging from .661 to .965 for test-retest reliability and from .748 to .958 for inter-rater reliability. While acknowledging certain limitations, this study's findings reaffirm the A-PPT's acceptable validity and reliability. This highlights its potential as a valuable assessment instrument for evaluating phonological processing skills within the Arabic-speaking population.

Assessing Phonological Processing in Children With Speech Sound Disorders

Purpose: Phonological processing skills, or using phoneme knowledge to process language, in preschool- and kindergarten-age children are an important indicator of children's future reading abilities. However, assessing phonological processing skills can be difficult in children with speech sound disorders because scoring often requires that children produce speech sound accurately. This tutorial presents assessment tasks that are appropriate for children with speech sound disorders to better identify children with phonological processing difficulties. Conclusions: The following phonological processing assessment tasks are recommended for children with speech sound disorders: receptive tasks for phonological awareness, the Syllable Repetition Task for phonological memory, and limited letter choices for rapid automatized naming in phonological retrieval tasks. These tasks can be modified for multilingual children. Appropriate assessment of phonological processing skills will help speech-language pathologists in differential diagnosis of children with true phonological processing difficulties and children whose speech sound errors may mask phonological processing abilities. Assessment of phonological processing skills is particularly important for children with speech sound disorders, whose speech errors may be evidence of phonological processing difficulties.

Long-Term Outcomes for Individuals With Childhood Apraxia of Speech.

The study's primary aims were to describe the long-term speech outcomes for adolescents and young adults with a history of childhood apraxia of speech (CAS) and to examine the association of persistent speech sound errors with measures of literacy skills, phonological processing, motor speech production, and parent report of early motor difficulty. Data from a large longitudinal 25-year study were used to explore outcomes for 32 individuals with a history of CAS, ages 12;6 (years;months) to 25 years (M = 17.4, SD = 4.7). Persistent and nonpersistent groups were compared on decoding, phonological processing, multisyllabic word repetition, diadochokinetic rate, and parent report of motor involvement. Parametric (Welch's t tests) and nonparametric tests (Wilcoxon and Fisher exact tests) were used to identify differences between the groups' distributions. Developmental trajectories of speech production were plotted. Outcomes for individuals with CAS are highly variable, with some demonstrating speech sound errors into adolescence and young adulthood. Speech sound errors were primarily on later developing sounds. Persistence was significantly associated with early motor difficulties. Difficulties with multisyllabic words, phonological processing, and literacy were often present regardless of persistence or nonpersistence of speech errors. Children with CAS are at risk for persistent speech sound errors into adulthood. For children showing limited progress with more traditional speech therapy, alternative interventions should be explored. Individuals with persistent speech sound errors are more likely to have a history of early motor deficits. Regardless of persistence, participants with CAS demonstrated ongoing weaknesses in literacy, phonological processing skills, and complex speech production tasks.

Interpretation of Misarticulated Words by Children With and Without Speech Sound Disorders.

Children with speech sound disorders (SSDs) often struggle with forming early representations for phonemes and words, which could impact their speech production as well as their lexical access. This difficulty may limit their ability to accurately identify nonexemplar productions of words, such as developmental misarticulations produced by peers. The purpose of this study was to examine word interpretation of misarticulated words by children with SSD. Seventeen monolingual English-speaking preschoolers were assessed for language, phonological processing, and articulation skills. Participants heard three types of words: accurate productions (e.g., "leaf"), common misarticulated productions (e.g., "weaf"), uncommon misarticulated productions (e.g., "yeaf"), and unrelated nonwords (e.g., "gim"). Children were presented with these words aurally and asked to select the picture that matched what they heard-either a real object or a blank square. The proportion of real object picture selections was calculated for each word type and compared within subjects. The findings indicate that children with SSD reliably associated common misarticulated words with pictured objects more frequently than they did in the uncommon misarticulation condition. These results were compared between subjects to typically developing (TD) peers' responses using a one-way analysis of variance. The results indicate that children with SSD identified common substitutions as real object pictures more often than TD peers. The results of this study suggest that children with SSD are sensitive to the commonness of misarticulations; however, they accept common substitutions as real object pictures significantly more often than TD peers.

Cognitive-linguistic skills and vocabulary knowledge breadth and depth in children’s L1 Chinese and L2 English

AbstractThis study examined the correlates of different aspects of vocabulary knowledge in L1 Chinese and L2 English in Hong Kong bilingual children (N = 481, age = 6–12 years old). Their nonverbal IQ, cognitive-linguistic skills, receptive and expressive vocabulary knowledge breadth, and vocabulary knowledge depth in Chinese and English were measured. Results demonstrated that morphological awareness was uniquely correlated with different aspects of vocabulary knowledge across Chinese and English. Phonological processing skills played different roles in vocabulary knowledge in L1 and L2. In addition, receptive vocabulary breadth uniquely contributed to expressive vocabulary breadth across languages. Moreover, both receptive and expressive vocabulary breadth contributed to vocabulary knowledge depth in L1 Chinese and L2 English. The findings highlight some shared and unique aspects of different vocabulary constructs across languages.

Phonological Processing Skills of Children with Phonological Delay and Phonological Disorder

Objectives: The purpose of this study was to examine the phonological processing skills between children with phonological delay and phonological disorder compared to those of typically developing children. This study aimed to explore whether children with phonological delay and phonological disorder show general or specific weakness on phonological processing skills and if the phonological processing skills can differentiate children with phonological delay from children with phonological disorder. Methods: The participants were 27 children with speech sound disorders (SSDs) and 20 typically developing children. Children with SSDs consisted of 10 children with phonological delay and 17 children with phonological disorder. The tasks for phonological processing skills involved phonological awareness at the levels of word, syllable, body-coda, and phoneme; phonological memory tests including nonword repetition and sentence repetition; and phonological retrieval through rapid automatized number naming test. Results: Children with phonological disorder showed significantly lower phonological awareness at word level than typically developing children and they also exhibited significantly lower nonword repetition than children with phonological delay as well as typically developing children. Both children with phonological delay and disorder performed less well on rapid automatized naming than typically developing children. Conclusion: This study suggests that children with phonological disorder are at higher risk for deficits in phonological processing, and their weakness in nonword repetition which taps phonological memory is more prominent than in children with normal speech or phonological delay.

Фонологический дефицит и его мозговые корреляты у детей с дислексией

This work is a comprehensive cross-methodological experimental study of phonological processing disorders in dyslexic Russian-speaking children. We developed and standardized a Russian-language test battery to assess phonological processing skills (The Russian Test of Phonological Processing), wich we then used to assess the features of phonological deficits in children with dyslexia and conduct an analysis of reading difficulties and their structural brain correlates using modern methods of videooculography and neuroimaging. The first phase’s findings revealed that more complex phonological tests were also more difficult, whereas children’s performance in these tests was found to be a significant predictor of reading speed. The project’s second phase identified five common patterns of eye movements during reading in children with and without dyslexia. We discovered that children with dyslexia exhibit the same patterns as their typically developing peers, albeit with a three-year delay. Finally, the third phase revealed significant differences in gray matter volume in the cerebellum, insula, and parietal lobule between group of children with dyslexia and control group of typically developing children.
 These findings have significant implications for clinical practice, interdisciplinary research on dyslexia, and possibly the educational system.

The Effects of an On-line Reading Intervention on the Development of English Decoding Skills among Moroccan Adult Struggling Readers

The present study examines the role of an intensive phonics-based online reading program in developing decoding skills among a group of low-intermediate adult learners. All the participants taking part in this experiment are defined as low-level, or struggling, readers. A lexical-decision task is administered to a total of twenty-four students divided into two main groups: treatment and control groups. The administration of the computer-based test is twofold and is done over two main phases: pre- and post-intervention. The online reading intervention, which is tailored to cover English orthographic knowledge and sound processing of high and low frequency words, is exclusively designed for the experimental group for four weeks. The intervention group demonstrates a significant improvement in spelling skills, reading speed and phoneme awareness. The results, on the one hand, suggest the importance of L2 print exposure which fosters phonological processing skills. On the other hand, the findings show that word identification processes operate at a pre-lexical access stage and are rudimentary to recognize and activate a lexical item.

Developmental changes in the contributions of phonological processing skills to Chinese character reading and arithmetic

This study examined the associations of phonological processing skills with reading and arithmetic ability in Chinese kindergartners (Mage = 5.56 years), third graders (Mage = 9.72 years), and fifth graders (Mage = 11.75 years) (N = 413) of Han descent. The results showed that phonological awareness and rapid automatized naming (RAN) showed stronger relations than phonological memory with reading and arithmetic across grades. Furthermore, the associations of phonological awareness and RAN with reading were much stronger in kindergartners than in primary school children, whereas their relationships with arithmetic remained stable across grades. Among phonological skills, phonological awareness has a unique influence on arithmetic that is independent of Chinese character reading in third-graders and kindergartners. In contrast, RAN uniquely explained the variation in arithmetic skills in fifth graders when reading was statistically controlled for. These findings have important implications for understanding the co-development of reading and arithmetic across grades and raise the possibility of training in phonological awareness and/or RAN to help children at risk for learning disabilities.

The association of prenatal cocaine exposure with expressive and receptive language skills, phonological processing and reading ability at age 17

ObjectivePrenatal cocaine exposure (PCE) has been associated with small but significant effects on language development in childhood and early adolescence. This study examined whether this association persists into later adolescence and what relationship language skills may have with reading proficiency in this population. MethodsEnrolled were 338 (167 with PCE, 171 with NCE or no cocaine exposure) 17-year-olds recruited at birth who, together with their current caregiver, were seen as part of a 17-year follow-up. Participants were given assessments of reading achievement (WIAT-III), receptive and expressive language (CELF-IV), and phonological processing (CTOPP). Relationships between PCE status and language outcomes were modeled using multiple linear regression controlling for environmental and caregiver factors, and other prenatal substance exposures. ResultsAdolescents with PCE scored lower in areas of phonological processing and reading related skills compared to adolescents with NCE. PCE by sex interactions were identified on language, memory and spoken language comprehension, with lower scores for girls with PCE compared to girls with NCE. ConclusionThese findings suggest the persistence of PCE's relationship with phonological awareness well into adolescence. PCE was also associated with lower scores on measures of skills related to reading ability, which may be a manifestation of the observed deficits in phonological processing.

Stimulus- and Person-Level Variables Influence Word Production and Response to Anomia Treatment for Individuals With Chronic Poststroke Aphasia.

The impact of stimulus-level psycholinguistic variables and person-level semantic and phonological processing skills on treatment outcomes in individuals with aphasia requires further examination to inform clinical decision making in treatment prescription and stimuli selection. This study investigated the influence of stimulus-level psycholinguistic properties and person-level semantic and phonological processing skills on word production accuracy and treatment response. This retrospective analysis included 35 individuals with chronic, poststroke aphasia, 30 of whom completed typicality-based semantic feature treatment. Mixed-effects logistic regression models were used to predict binary naming accuracy (a) at baseline and (b) over the course of treatment using stimulus-level psycholinguistic word properties and person-level semantic and phonological processing skills as predictors. In baseline naming, words with less complex lexical-semantic and phonological properties showed greater predicted accuracy. There was also an interaction at baseline between stimulus-level lexical-semantic properties and person-level semantic processing skills in predicting baseline naming accuracy. With treatment, words that were more complex from a lexical-semantic standpoint (vs. less complex) and less complex from a phonological standpoint (vs. more complex) improved more. Individuals with greater baseline semantic and phonological processing skills showed a greater treatment response. This study suggests that future clinical research and clinical work should consider semantic and phonological properties of words in selecting stimuli for semantically based treatment. Furthermore, future clinical research should continue to evaluate baseline individual semantic and phonological profiles as predictors of response to semantically based treatment. https://doi.org/10.23641/asha.21256341.

Phonological processing skills in children with speech sound disorder: A multiple case study approach.

Children with speech sound disorder (SSD) are at increased risk of reading difficulties due to poor phonological processing skills. However, the extent to which children with SSD demonstrate weaknesses on specific or all phonological processing tasks is not well understood. To examine the phonological processing abilities of a clinically identified sample of children with SSD, with and without reading difficulties. To determine the extent to which the proportion of children with concomitant SSD and reading difficulties exhibited weaknesses in specific areas of phonological processing, or a more general phonological deficit. Data were obtained from 157 school-aged children (Mage = 77 months, SD = 7.01) in receipt of school-based speech therapy. Approximately 25% of the sample was identified as poor readers, based on a standardized measure of word decoding. We compared the proportion of children who scored at or below 1 SD below the mean, or the bottom 16th percentile, on measures of phonological awareness, rapid automatized naming and verbal short-term memory among those identified as poor readers and good readers. Children with SSD demonstrated a range of phonological processing difficulties, particularly on the measure of verbal short-term memory. No specific skill differentiated groups of children with SSD with and without reading difficulties; however, those classified as poor readers on the word-decoding measure exhibited more widespread difficulties, even after controlling for language ability. Results support a cumulative risk model such that children with SSD and reading difficulties are likely to demonstrate generally poor phonological processing abilities. What is already known on the subject Children with SSD are at heightened risk of reading difficulties, particularly if their SSD persists into school age. However, not all children with SSD experience reading problems. Research aimed at determining which children are at the highest risk is mixed as to how best to identify which children with SSD are most likely to experience reading difficulties. What this paper adds to existing knowledge The study used a multiple case study approach to determine if performance on phonological processing skills might differentiate children with SSD who were poor readers from those who were good readers. As a group, children with SSD exhibited poor verbal short-term memory but relatively intact rapid automatized naming skills. No one phonological processing skill differentiated children who were poor readers from good readers. However, children with reading difficulties appeared to experience more general difficulties across phonological processing tasks, even after controlling for language abilities. What are the potential or actual clinical implications of this work? A single deficit (i.e., speech sound production) is not sufficient data to make a complete diagnosis or treatment decisions. Multiple sources of data, including several aspects of phonological processing, should be obtained to understand reading risk in children with SSD.

The relationship between phonological processing and arithmetic in children with learning disabilities.

Phonological processing skills have not only been shown to be important for reading skills, but also for arithmetic skills. Specifically, previous research in typically developing children has suggested that phonological processing skills may be more closely related to arithmetic problems that are solved through fact retrieval (e.g., remembering the solution from memory) than procedural computation (e.g., counting). However, the relationship between phonological processing and arithmetic in children with learning disabilities (LDs) has not been investigated. Yet, understanding these relationships in children with LDs is especially important because it can help elucidate the cognitive underpinnings of math difficulties, explain why reading and math disabilities frequently co-occur, and provide information on which cognitive skills to target for interventions. In 63 children with LDs, we examined the relationship between different phonological processing skills (phonemic awareness, phonological memory, and rapid serial naming) and arithmetic. We distinguished between arithmetic problems that tend to be solved with fact retrieval versus procedural computation to determine whether phonological processing skills are differentially related to these two arithmetic processes. We found that phonemic awareness, but not phonological memory or rapid serial naming, was related to arithmetic fact retrieval. We also found no association between any phonological processing skills and procedural computation. These results converge with prior research in typically developing children and suggest that phonemic awareness is also related to arithmetic fact retrieval in children with LD. These results raise the possibility that phonemic awareness training might improve both reading and arithmetic fact retrieval skills. RESEARCH HIGHLIGHTS: Relationships between phonological processing and various arithmetic skills were investigated in children with learning disabilities (LDs) for the first time. We found phonemic awareness was related to arithmetic involving fact retrieval, but not to arithmetic involving procedural computation in LDs. The results suggest that phonemic awareness is not only important to skilled reading, but also to some aspects of arithmetic. These results raise the question of whether intervention in phonemic awareness might improve arithmetic fact retrieval skills.

The Role of Proficiency in Kashmiri Language in Phonological Processing Skills: A Cognitive-linguistic Approach

Language reflects the general aspects of human cognition and it works in terms of generalities, i.e. in terms of categories (Cruse, 2000). So, any of the linguistic expressions, whether it’s a phone, word, syllable or a sentence ends up in the representation of a category referring to a something that is usually aimed at sufficing the need for communication. These categories are conceptual or can be referred to as the abstract mental constructs. However, language is not an autonomous cognitive faculty which implies that language is not exactly an innate cognitive module and is not separated from non-linguistic cognitive abilities (Craft & Cruse, 2004). This study reports on the role of proficiency of Kashmiri language in phonological processing of illiterate native Kashmiri speakers. A total number 40 participants (20 Literate; 20 Illiterate), divided into two groups; were tested for Lexical Decision, Random Automatized Naming, Initial Phoneme Deletion, and Final Phoneme Deletion. The results suggested that the performance of both the groups was affected by Literacy and Proficiency in their native language i.e. Kashmiri. The effect of literacy on phonological processing was in consistence with the available literature however, the performance by illiterates was not worked out. This study attempted to find out the reasons for the performance of illiterates, and it was found that the illiterates can perform almost similar to those of literates on phonological awareness tasks because the proficiency in their native language enhances their phonemic and phonological awareness skills. Hence, the proficiency in Kashmir language has a role in phonological processing of illiterates.

How language skills and working memory capacities explain mathematical learning from preschool to primary school age: Insights from a longitudinal study.

Between the age span of 3 to 6 years the foundation for children’s mathematical learning (i.e., numerical abilities and cognition) are laid. However, the developing relations between mathematical skills, language, and working memory starting at preschool age and evolving into primary school age are not well understood. Adopting an empirically validated analysis model, the present study examines in detail longitudinal interdependencies between mathematical skills, a wide range of language skills, and working memory components underlying the mathematical learning process of 41 German preschool children (41.5% female) spanning ages 4 to 6. Phonological processing skills and expressive grammar skills emerged as the most significant language skills for the process of children’s mathematical learning across the investigated age span. Within the latter, children’s phonological processing skills and expressive grammar skills were supported by children’s word expression abilities. The phonological loop emerged as the most important working memory component for children’s early mathematical learning between ages 4 to 6. Furthermore, a wide array of language skills were associated with complex information and storage processes within this mathematical learning process. In conclusion, the present findings provide a more detailed and deeper insight into the learning process of children’s number concept, emphasizing the influence of phonological and particularly grammatical skills.

Predicting Word Reading Deficits Using an App-Based Screening Tool at School Entry.

BackgroundReading is a crucial competence associated with academic development, mental health, and social adaptation. Reading difficulties are often detected at a late stage, with a possible negative impact on long-term reading development and secondary developmental disadvantages. The first manifestations of reading difficulties can be identified by word reading deficits in first and second grade, paving the way for specific interventions. For widespread implementation, instruments must be easy to use and motivating for children.ObjectivesDevelopment and validation of an economical, well-accepted, and accurate screening tool composed of the domains of phonological information processing, language skills, and non-verbal intelligence in regular school settings.DesignIn 2020, the screening tool was used on a sample of 409 first graders between the second and fifth weeks of school in a one-to-one setting. Additionally, information on parental education and the use of German and/or other languages by the child was collected using a parental questionnaire. A follow-up involving the use of established standardized word reading tests was conducted at the end of the first school year.ResultsA five-variable screening tool consisting of the dimensions of phonological information processing (letter knowledge, rapid naming, and phonological awareness) and linguistic skills (receptive vocabulary and morphosyntax) showed statistical relevance (AUC = 0.78; sensitivity 0.80, specificity 0.74) for predicting word reading problems concerning reading speed (<16th percentile) at the end of first grade, whereas gender, first language, and age of first exposure to the German language did not contribute to the prediction. The instrument was well accepted by the children and screeners and can be administered within an acceptable time frame.ConclusionWord reading deficits at the end of first grade can be predicted by the use of an app-based screening tool at school entry that includes phonological information processing and language skills. Further validation and assessment of empirical feasibility data are needed to support the screening instrument for German orthography.

A Diffusion Tensor Imaging Study on the White Matter Structures Related to the Phonology in Cantonese-Mandarin Bilinguals.

Cantonese and Mandarin are logographic languages, and the phonology is the main difference between the two languages. It is unclear whether the long-term experience of Cantonese–Mandarin bilingualism will shape different brain white matter structures related to phonological processing. A total of 30 Cantonese–Mandarin bilinguals and 30 Mandarin monolinguals completed diffusion-weighted imaging scan and phonological processing tasks. The tractography and tract-based spatial statistics were used to investigate the structural differences in the bilateral superior longitudinal fasciculus (SLF), inferior longitudinal fasciculus (ILF), and inferior fronto–occipital fasciculus (IFOF) between Cantonese–Mandarin bilinguals and Mandarin monolinguals. The post-hoc correlation analysis was conducted to investigate the relationship between the different structures with phonological processing skills. Compared to the Mandarin monolinguals, the Cantonese–Mandarin bilinguals had higher fractional anisotropy (FA) along the left ILFs higher mean diffusivity (MD) along the right IFOF and the temporoparietal segment of SLF (tSLF), higher axial diffusivity (AD) in the right IFOF and left ILF, and lower number of streamlines in the bilateral tSLF. The mean AD of the different voxels in the right IFOF and the mean FA of the different voxels in the left ILF were positively correlated with the inverse efficiency score (IES) of the Cantonese auditory and Mandarin visual rhyming judgment tasks, respectively, within the bilingual group. The correlation between FA and IES was different among the groups. The long-term experience of Cantonese–Mandarin bilinguals shapes the different brain white matter structures in tSLF, IFOF, and ILF. Compared to the monolinguals, the bilinguals’ white matter showed higher diffusivity, especially in the axonal direction. These changes were related to bilinguals’ phonological processing.
