Background: Speech and language are interconnected systems, and language disorder often co-occurs with childhood apraxia of speech (CAS) and non-CAS speech sound disorders (SSDs). Potential trade-off effects between speech and language in connected speech in children without overt language disorder have been less explored. Method: Story retell…

This article compares the traditional and modern "speech production" patterns of the Kazakh language. By identifying the advantages of traditional speech structuring, the study proposes mechanisms for revitalizing modern Kazakh speech production, which is becoming increasingly simplified and distanced from its cognitive-aesthetic power…

Background: Little is known about the spontaneous speech characteristics of young children with language delay in Mandarin, relative to their peers. Until the recent development of standardized language assessments normed in China on Mandarin-speaking children, it was difficult to independently identify atypically developing children to study…

Background: The detection and description of language impairments in neurodegenerative diseases like Alzheimer's Disease (AD) play an important role in research, clinical diagnosis and intervention. Various methodological protocols have been implemented for the assessment of morphosyntactic abilities in AD; narrative discourse elicitation tasks…

Background: Despite its importance, in-depth analysis of connected speech is often neglected in the diagnosis of primary progressive aphasia (PPA) -- especially for the logopenic variant (lvPPA) for which unreliable differential diagnosis has been documented. Only a few studies have been conducted on this topic in lvPPA. Aims: The aim of this…

Purpose: This study examined the frequency, direction, and structural characteristics of code-switching (CS) during narratives by Spanish-English bilingual children with and without developmental language disorder (DLD) to determine whether children with DLD exhibit unique features in their CS that may inform clinical decision-making. Method:…

Singular "they" is becoming increasingly common and accepted, but many people find it difficult to learn, instead making seemingly-counterintuitive errors like "she uses they/them pronouns." Existing pronoun production models argue that speakers select pronouns based on morphosyntactic information associated with a name, or…

The article, "morphosyntactic peculiarities of the speech of children with Down's syndrome", treats, important aspects of the study of two adjacent branches of linguistics, namely, psycholinguistics and neurolinguistics-Language development of the child accompanied by speech disorders, on the other hand, those morphosyntactic features…

Given the rich bound morphology of Spoken Arabic, an attempt was made here to construct a developmental measure corresponding to the mean length utterance (MLU) in English and to morpheme-per-utterance (MPU) in Hebrew. The adaptation to Arabic resulted in a new measurement termed Arabic-MPU, that was experimentally tested on a sample of 98…

The current study examined the extent to which first language (L1) utterance fluency measures can predict second language (L2) fluency and how L2 proficiency moderates the relationship between L1 and L2 fluency. A total of 104 Japanese-speaking learners of English completed different argumentative speech tasks in their L1 and L2. Their speaking…

The present study investigated the role of morphosyntactic information in the acquisition of transitive and intransitive verb argument structures (VAS) in the Japanese language, which allows massive omissions of arguments and case markers. In particular, we investigated how the 'variation sets' proposed by Küntay and Slobin work in Japanese.…

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.…

While semantic and syntactic properties of verb meaning can impact the success of verb learning at a single age, developmental changes in how these factors influence acquisition are largely unexplored. We ask whether the impact of syntactic and semantic properties on verb vocabulary development varies with age and language ability for toddlers…

This study describes academic literacy development during mid-adolescence, when learners need to adjust to the demands of academic discourse as a gateway to linguistic adulthood. Unlike most research to date, which is cross-sectional and detached from disciplinary content, this study provides a two-year longitudinal description of academic…

Research in language development has only recently begun to focus on the inherent variability of language. Previous studies have explored at what age children begin to produce variable linguistic forms and how these forms progress through development. While children produce adult-like variation early on, some variable forms take longer to acquire…
