English-French bilingual children’s phonological awareness and vocabulary skills

This study examined the relationship between English-speaking children’s vocabulary skills in English and in French and their phonological awareness skills in both languages. Forty-four kindergarten-aged children attending French immersion programs were administered a receptive vocabulary test, an expressive vocabulary test and a phonological awareness test in English and French. Results showed that French phonological awareness was largely explained by English phonological awareness, consistent with previous findings that phonological awareness skills transfer across languages. However, there was a small unique contribution from French expressive vocabulary size to French phonological awareness. The importance of vocabulary skills to the development of phonological awareness is discussed.Cette étude porte sur la relation entre le vocabulaire anglais, le vocabulaire français et la conscience phonologique des enfants bilingues de langue maternelle anglaise. On a administré, en anglais et en français, à 44 enfants d’âge préscolaire inscrits en immersion française un test de vocabulaire réceptif, un test de vocabulaire expressif, ainsi qu’un test mesurant leur conscience phonologique. Les résultats indiquent que la conscience phonologique de ces élèves, en anglais et en français, s’explique largement par leur conscience phonologique en anglais, confirmant ainsi les résultats d’études antérieures qui avaient démontré la transférabilité de la conscience phonologique d’une langue à l’autre. Toutefois, on a observé que le vocabulaire expressif en français contribue de façon limitée mais significative à la conscience phonologique en français. Une discussion est menée sur l’importance du vocabulaire de l’enfant dans le développement de sa conscience phonologique.&nbsp

Auditory-Motor Learning during Speech Production in 9-11-Year-Old Children

BACKGROUND: Hearing ability is essential for normal speech development, however the precise mechanisms linking auditory input and the improvement of speaking ability remain poorly understood. Auditory feedback during speech production is believed to play a critical role by providing the nervous system with information about speech outcomes that is used to learn and subsequently fine-tune speech motor output. Surprisingly, few studies have directly investigated such auditory-motor learning in the speech production of typically developing children. METHODOLOGY/PRINCIPAL FINDINGS: In the present study, we manipulated auditory feedback during speech production in a group of 9-11-year old children, as well as in adults. Following a period of speech practice under conditions of altered auditory feedback, compensatory changes in speech production and perception were examined. Consistent with prior studies, the adults exhibited compensatory changes in both their speech motor output and their perceptual representations of speech sound categories. The children exhibited compensatory changes in the motor domain, with a change in speech output that was similar in magnitude to that of the adults, however the children showed no reliable compensatory effect on their perceptual representations. CONCLUSIONS: The results indicate that 9-11-year-old children, whose speech motor and perceptual abilities are still not fully developed, are nonetheless capable of auditory-feedback-based sensorimotor adaptation, supporting a role for such learning processes in speech motor development. Auditory feedback may play a more limited role, however, in the fine-tuning of children's perceptual representations of speech sound categories

The factors contributing to teacher predictions of spelling ability, and the accuracy of their assessments

In this study, teachers of kindergarten and Grade 1 French-speaking students indicated the likelihood their students would develop later writing difficulties. Results showed that language measures, language background, the education levels of parents, and home literacy practices predicted whether children would be identified as at-risk. Moreover children’s oral language skills accounted for even more of the variance in teacher ratings than other variables. Spelling performance assessed 1-year later from a subset of children indicated that the teacher predictions were accurate. Thus, teachers appear to be an effective source for predicting children’s future literacy performance

Development of a tool to screen risk of literacy delays in French-speaking children: PHOPHLO

Literacy is crucial for success, both professionally and personally. Oral language skills are closely related to literacy development in children. When a child has weak oral language skills, they will have difficulty achieving reading and writing competencies within the expected time frame. In this paper, we present results from a longitudinal and cross-sectional study of the relationship between oral language skills in pre-literate children, and one aspect of their literacy skills in early elementary school—specifically, spelling. The study was conducted with French-speaking children and French-language learners from Quebec, a population that has been understudied in this area. We developed a predictive tool that will allow teachers and other professionals to assess oral language skills in young children and to predict those children at risk for literacy difficulties. Specifically, we screened children’s speech perception, speech production, phonological awareness, and morphology production abilities at entry to first grade and predicted spelling skills at the end of second grade. The screening tool that we developed proved to have a sensitivity of 71% and a specificity of 93% as a screen for poor spelling abilities.La littératie est un élément crucial du succès à la fois professionnel et personnel. Les habiletés de langage oral sont intimement liées au développement de la littératie chez les enfants. En effet, lorsqu’un enfant a de faibles habiletés de langage oral, il aura plus de difficulté à développer ses habiletés de lecture et d’écriture dans les délais prévus. Nous présentons les résultats d’une étude longitudinale et transversale qui explore les liens entre les habiletés de langage oral chez des enfants n’ayant pas appris à lire ou à écrire et leurs habiletés de littératie au premier cycle du primaire. Cette étude a été menée auprès d’enfants franco-québécois natifs et non natifs, une population peu étudiée dans ce domaine. Nous avons créé un outil prédictif qui permettra aux enseignants et autres professionnels d’évaluer les habiletés de langage oral des enfants et de prédire ceux qui sont à risque de présenter des difficultés de littératie. Plus spécifiquement, nous avons évalué les habiletés de perception et de production de la parole, de conscience phonologique et de production morphologique d’enfants débutant leur première année du primaire. Nous avons prédit leurs habiletés d’orthographe à la fin de leur deuxième année (fin du premier cycle du primaire). L’outil développé a démontré une sensibilité de 71% et une spécificité de 93% pour dépister les faibles habiletés d’orthographe

Phonological and articulation treatment approaches in Portuguese children with speech and language impairments: a randomized controlled intervention study

Background In Portugal, the routine clinical practice of speech and language therapists (SLTs) in treating children with all types of speech sound disorder (SSD) continues to be articulation therapy (AT). There is limited use of phonological therapy (PT) or phonological awareness training in Portugal. Additionally, at an international level there is a focus on collecting information on and differentiating between the effectiveness of PT and AT for children with different types of phonologically based SSD, as well as on the role of phonological awareness in remediating SSD. It is important to collect more evidence for the most effective and efficient type of intervention approach for different SSDs and for these data to be collected from diverse linguistic and cultural perspectives. Aims To evaluate the effectiveness of a PT and AT approach for treatment of 14 Portuguese children, aged 4.0–6.7 years, with a phonologically based SSD. Methods & Procedures The children were randomly assigned to one of the two treatment approaches (seven children in each group). All children were treated by the same SLT, blind to the aims of the study, over three blocks of a total of 25 weekly sessions of intervention. Outcome measures of phonological ability (percentage of consonants correct (PCC), percentage occurrence of different phonological processes and phonetic inventory) were taken before and after intervention. A qualitative assessment of intervention effectiveness from the perspective of the parents of participants was included. Outcomes & Results Both treatments were effective in improving the participants’ speech, with the children receiving PT showing a more significant improvement in PCC score than those receiving the AT. Children in the PT group also showed greater generalization to untreated words than those receiving AT. Parents reported both intervention approaches to be as effective in improving their children's speech. Conclusions & Implications The PT (combination of expressive phonological tasks, phonological awareness, listening and discrimination activities) proved to be an effective integrated method of improving phonological SSD in children. These findings provide some evidence for Portuguese SLTs to employ PT with children with phonologically based SSD

Williams syndrome: a surprising deficit in oromotor praxis in a population with proficient language production

Williams Syndrome (WS) is a neurodevelopmental disorder of known genetic origin, characterized by serious delays in language onset yet relatively verbose, intelligible and fluent speech in late childhood and adulthood. How do motor abilities relate to language in this group? We investigated planning and co-ordination of the movement of the speech articulators (oromotor praxis) in 28 fluent-speaking individuals with WS, aged between 12–30 years. Results indicate that, despite their fluent language, oromotor praxis was impaired in WS relative to two groups of typically-developing children, matched on either vocabulary or visuospatial ability. These findings suggest that the ability to plan, co-ordinate and execute complex sensorimotor movements contribute to an explanation of the delay in expressive language early in development in this neurodevelopmental disorder. In the discussion, we turn to more general issues of how individual variation in oromotor praxis may account for differences in speech/language production abilities across developmental language disorders

Auditory-motor entrainment and phonological skills: precise auditory timing hypothesis (PATH)

Phonological skills are enhanced by music training, but the mechanisms enabling this cross-domain enhancement remain unknown. To explain this cross-domain transfer, we propose a precise auditory timing hypothesis (PATH) whereby entrainment practice is the core mechanism underlying enhanced phonological abilities in musicians. Both rhythmic synchronization and language skills such as consonant discrimination, detection of word and phrase boundaries, and conversational turn-taking rely on the perception of extremely fine-grained timing details in sound. Auditory-motor timing is an acoustic feature which meets all five of the pre-conditions necessary for cross-domain enhancement to occur (Patel, 2011, 2012, 2014). There is overlap between the neural networks that process timing in the context of both music and language. Entrainment to music demands more precise timing sensitivity than does language processing. Moreover, auditory-motor timing integration captures the emotion of the trainee, is repeatedly practiced, and demands focused attention. The PATH predicts that musical training emphasizing entrainment will be particularly effective in enhancing phonological skills

The case for morphophonological intervention: Evidence from a Greek-speaking child with speech difficulties

Intervention with children with speech and language difficulties has been proven beneficial compared with no treatment yet, knowing what type of intervention to provide remains a challenge. Studies of English-speaking children indicate that intervention targeting the production of morphological targets may have a positive effect on phonological aspects and vice versa. However, studies have not reported on generalization effects to untreated morphemes and little is yet known about morphological intervention in the context of a highly inflected language. The purpose of the current intervention case study was to investigate the effect of intervention in relation to phonological and morphological targets in Greek, a language characterized by complex inflectional morphology. A single subject research design was used with pre- and post-intervention assessment carried out. The participant was a four-year-old Greek-speaking boy with speech difficulties. The production of /s/, a phoneme used in multiple phonological and morphological contexts was targeted with alternating focus of intervention between phonological and morphological targets. Assessment took place at two levels: macro-assessment to monitor broad changes in speech; micro-assessment to measure therapy-specific changes in the production of treated targets and generalization to untreated targets and control items. There were four phases of intervention with a total of 24 hours of therapy. Significant improvement in performance accuracy was found between assessment scores immediately pre- and post-intervention. Intervention targeting the production of a phoneme in the word stem was not sufficient to accomplish the accurate production of morphemes requiring the same phoneme; intervention directly targeting morphemes was successful. Within-domain generalization was observed in both domains. Improved naming accuracy was observed post-intervention that was maintained at follow-up. The present study supports the case for morphophonological intervention. Morphological elements should be addressed in a comprehensive intervention for speech sound disorders

Speech production deficits in early readers: predictors of risk

Speech problems and reading disorders are linked, suggesting that speech problems may potentially be an early marker of later difficulty in associating graphemes with phonemes. Current norms suggest that complete mastery of the production of the consonant phonemes in English occurs in most children at around 6–7 years. Many children enter formal schooling (kindergarten) around 5 years of age with near-adult levels of speech production. Given that previous research has shown that speech production abilities and phonological awareness skills are linked in preschool children, we set out to examine whether this pattern also holds for children just beginning to learn to read, as suggested by the critical age hypothesis. In the present study, using a diverse sample, we explored whether expressive phonological skills in 92 5-year-old children at the beginning and end of kindergarten were associated with early reading skills. Speech errors were coded according to whether they were developmentally appropriate, position within the syllable, manner of production of the target sounds, and whether the error involved a substitution, omission, or addition of a speech sound. At the beginning of the school year, children with significant early reading deficits on a predictively normed test (DIBELS) made more speech errors than children who were at grade level. Most of these errors were typical of kindergarten children (e.g., substitutions involving fricatives), but reading-delayed children made more of these errors than children who entered kindergarten with grade level skills. The reading-delayed children also made more atypical errors, consistent with our previous findings about preschoolers. Children who made no speech errors at the beginning of kindergarten had superior early reading abilities, and improvements in speech errors over the course of the year were significantly correlated with year-end reading skills. The role of expressive vocabulary and working memory were also explored, and appear to account for some of these findings
