Purpose: This study examined the effect of Vocabulary Acquisition and Usage for Late Talkers (VAULT) treatment on toddlers' expressive vocabulary and phonology. Parent acceptability of VAULT treatment was also considered. Method: We used a nonconcurrent multiple baseline single case experimental design with three late talking toddlers aged 21-25…

Background: Recent evidence suggests that pre-school children with co-occurring phonological speech sound disorder (SSD) and expressive language difficulties are at a higher risk of ongoing communication and literacy needs in comparison with children with these difficulties in isolation. However, to date there has been no systematic or scoping…

Purpose: This study reexamines the claim that difficulty forming memories of words comprising uncommon sound sequences (i.e., low phonological neighborhood density words) is a determinant of delayed expressive vocabulary development (e.g., Stokes, 2014). Method: We modeled communicative development inventory data from (N = 442) 18-month-old…

Recent studies highlight the important contribution of phonological working memory (PM) in the early stages of both native and foreign language development. However, research on the effects of PM training on language development is very limited. This study aimed at assessing the effectiveness of a PM training educational intervention as a means of…

Background: Language disorder and associated vocabulary difficulties can persist into adolescence, and can impact on long-term life outcomes. Previous reviews have shown that a variety of intervention techniques can successfully enhance students' vocabulary skills; however, none has investigated vocabulary intervention specifically for adolescents…

Forty-two adolescents with Down syndrome (DS) ages 10 to 21 years completed a battery of language and phonological memory measures twice, 2 years apart. Individual differences were highly stable across two years. Receptive vocabulary scores improved, there was no change in receptive or expressive grammar scores, and nonword repetition scores…

A large linguistic distance exists between spoken Arabic and the Modern Standard Arabic (MSA) the literary language (a diglosia). Novice readers, therefore, struggle with the complex orthography of Arabic as well as the mastering of MSA. Here, we tested whether structured activities in MSA would advance kindergarteners' MSA aptitude by the end of…

A randomized control intervention study was conducted to evaluate the effects of the highly structured Heidelberg Parent-Based Language Intervention (HPLI). The outcomes of 43 children (n = 23 intervention, n = 20 control) who had been identified as late talkers during routine developmental check-ups carried out in pediatric practices at the age…

This study taught the passive to two children with specific language impairment (aged 8;1 and 8;2). It employed usage-based principles including "constructional grounding"; using short structures as the basis for acquiring long structures, and "construction conspiracy"; encouraging analogies between partially overlapping…

Word-retrieval and rapid naming abilities play an important role in language processing and cognitive development. Researchers have demonstrated that early language difficulties may lead to later reading impairments and several decades of research has convincingly demonstrated that rapid automatized naming is a powerful predictor of concurrent and…

Although physical therapy (PT) is effective in improving motor function in children with developmental coordination disorder (DCD), insufficient data are available on the impact of this intervention in children with combined attention-deficit-hyperactivity disorder (ADHD) and DCD. This prospective study aimed to establish the prevalence of DCD…

This longitudinal project identified young children at risk of literacy difficulties and asked why some of these children fail to benefit from phonologically based intervention. Reception class children were screened to identify a group at risk of literacy difficulties and a matched group of children not at risk. Profiles were compiled for each…

Associations among expressive phonological development, metaphonological skills, and spelling performance are examined. Suggestions are offered for analyzing and remediating phonological deficiencies of children with phonologically based spelling problems. A case study of a third grader with spelling problems exemplifies assessment and…

This study, involving 26 children (ages 44-70 months) with impairments in grammar and phonology, found that children receiving either a clinician-administered or parent-administered intervention showed gains in expressive grammar, but there were no indirect effects on subjects' phonological production. Language intervention approaches for young…

Two children (ages four and five) with word-finding deficits characterized largely by semantic substitutions participated in a treatment involving phonological information about target words. Treatment resulted in reduction not only of occasional phonological word-finding substitutions but also of the large number of semantic word-finding…
