Background: Language assessment is a key element of evaluations of children and adolescents with neurodevelopmental disorders (NDDs). The present study examined the validity of a gaze-based receptive language index (RLI) in predicting language test results.Method: Participants included toddlers, pre-school, and school age children and adolescents…

Although non-native English speakers have been defined as a single distinct group in the most research literature, it has been relatively recently argued that they extensively vary in socio-cultural background, socio-economic status (SES), and parental education background wherein they grow cognitively. The present research, therefore, was…

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…

Scholars debate whether musical and linguistic abilities are associated or independent. In the present study, we examined whether musical rhythm skills predict receptive grammar proficiency in childhood. In Experiment 1, 7- to 17-year-old children (N = 68) were tested on their grammar and rhythm abilities. In the grammar-comprehension task,…

Language abilities in adolescents with autism spectrum disorders (ASDs) are variable and can be challenging to ascertain with confidence. This study aimed to compare and evaluate different forms of language assessment: standardized language testing, narrative analysis and parent/teacher reports. 14 adolescents with ASD and 14 typically developing…

This article reports a meta-analysis of 42 experiments in 33 published studies involving processing instruction (PI) and production-based instruction (PB) used in the PI studies. The comparative effectiveness of PI and PB showed that although PI was more effective than PB for developing receptive knowledge, PB was just as effective as PI for…

Young people from areas of socioeconomic disadvantage (SED) are more likely to present with language difficulties, particularly vocabulary difficulties. Studies have shown the effectiveness of vocabulary interventions for children with language impairment but not for adolescents from areas of SED. This article aims to establish the effectiveness…

Background: The nature of speech disorders in individuals with Down Syndrome (DS) remains controversial despite various explanations put forth in the literature to account for the observed speech profiles. A high level of word production inconsistency in children with DS has led researchers to query whether the inconsistency continues into…

As the language presentation of children with attention deficit (hyperactivity) disorder (ADHD) is highly complex, this study aims to delineate the profile of a cohort of 40 children with ADHD, aged between 9 and 12 years, attending a child and adolescent mental health service (CAMHS). Speech and language therapists (SLTs) assessed the children on…

Background: Research has consistently documented a relationship between phonological short-term memory skills (STM) and specific language impairment (SLI). This study reports on the development of phonological STM abilities over 3 years in 80 young adolescents with a history of SLI, investigating the nature of the relationship between phonological…

The usefulness of the Preschool Preposition Test (PPT) as a cognitive screening and diagnostic tool for handicapped children is demonstrated through results of eight independent studies. The subjects were 354 children and youths, aged two to 20 years, with various handicaps: mentally retarded, autistic-like, moderately emotionally disturbed,…
