Purpose: To avoid misdiagnosis with developmental language disorder (DLD) in bilingual children, it is recommended to evaluate both languages. However, unlike their monolingual peers, bilingual children acquire their heritage language under adverse input conditions. Focusing on Levantine Arabic, the study evaluates the clinical utility of a…

Background and aims: Nongenerative speech is the rote repetition of words or phrases heard from others or oneself. The most common manifestations of nongenerative speech are immediate and delayed echolalia, which are a well-attested clinical feature and a salient aspect of atypical language use in autism. However, there are no current estimates of…

Purpose: Little is known about the specific nature of language abilities of autistic adolescents and young adults with language impairment (LI), limiting our knowledge of developmental trajectories and ability to develop efficacious speech/language supports. An important first step is establishing proof of concept of identification of LI in this…

Background: Early and effective treatment for children with developmental language disorder (DLD) is important. Although a growing body of research shows the effects of interventions at the group level, clinicians observe large individual differences in language growth, and differences in outcomes across language domains. A systematic…

Purpose: Several studies have reported that "useful speech" at 5 years of age predicts outcomes in individuals with autism spectrum disorder (ASD), but this skill has been vaguely defined. This study investigates which specific aspects of expressive language in children with ASD best predict adult language and communication outcomes.…

Purpose: Phonological complexity is known to be a good index of developmental language disorder (DLD) in normal-hearing children, who have major difficulties on some complex structures. Some deaf children with cochlear implants (CIs) present a profile that evokes DLD, with persistent linguistic difficulties despite good audiological and…

The acquisition of passives is well-studied in many languages, with evidence of crosslinguistic differences in the age at which passives are acquired. The aim of this study is to add to the existing knowledge of child acquisition of passives by providing data from Afrikaans and isiXhosa, two under-researched and typologically different languages…

This study aimed at examining the contribution of various linguistic components to reading comprehension (RC) in the seventh and ninth grades and to compare this contribution between two groups: children with typical development and those with reading disorders (RD). This was done by testing the relative contribution of phonological awareness,…

In this study, we explored the role of emerging inhibitory control skills in language acquisition in 62 typically developing children aged 24-32 months and investigated whether early inhibitory control skills are longitudinally associated with language outcome. Specifically, we focused on two different inhibitory processes that develop…

Purpose: The differential diagnosis of developmental language disorder (DLD) in bilingual children represents a unique challenge due to their distributed language exposure and knowledge. The current evidence indicates that dual-language testing yields the most accurate classification of DLD among bilinguals, but there are limited personnel and…

Purpose: Children with developmental language disorder sometimes spontaneously repeat clinician models of morphemes targeted for treatment. We examine how spontaneous repeating of clinician models in the form of recasts associates with improved child production of those emerging morphemes. Method: Forty-seven preschool children with developmental…

Children with Developmental Language Disorder are likely to experience difficulties with morphosyntax, especially regular past tense marking. Few studies have evaluated the effectiveness of intervention to improve morphosyntax in young school-aged children with DLD. This study investigated the efficacy of combined explicit and implicit…

A systematic review of research on the effects of interventions that include communication partner modeling of aided augmentative and alternative communication (AAC) on the language acquisition of individuals with complex communication needs was conducted. Included studies incorporated AAC modeling as a primary component of the intervention,…

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…

We examined sources of morphological variability in second language (L2) learners of Spanish whose native language (L1) is English, with a focus on L1-L2 similarity, morphological markedness, and knowledge type (receptive vs. expressive). Experiment 1 uses event-related potentials to examine noun-adjective number (present in L1) and gender…
