Purpose: The goal of this work was to examine the semantic and syntactic properties of the vocabularies of autistic and non-autistic infants and toddlers to see if children in these two groups know different kinds of words. We focused on both receptive and expressive vocabularies. For expressive vocabulary, we looked only at the "active"…

Purpose: This study presents a comprehensive exploration of lexical and grammatical development in Palestinian Arabic (PA). The study aims to test the validity of the Palestinian Arabic Communicative Development Inventory (PA-CDI) as well as generate growth curves for lexical and morphosyntactic development, examine the order of emergence of both…

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…

Among the Altaic languages, Turkic and Mongolian have a lot of similarities due to their prolonged contact and a common lineage. The two languages share several parallels in vocabulary, sound correspondence, phonotactic rules, and grammar. This study aimed to explore the comparative-historical aspects of Turkic-Mongolian language parallels in…

As integrated writing tasks in large-scale and classroom-based writing assessments have risen in popularity, research studies have increasingly concentrated on providing validity evidence. Given the fact that most of these studies focus on adult second language learners rather than younger ones, this study examined the relationship between written…

The current paper aims to search and summarise the current literature on the linguistic aspect of the Orang Asli languages in Malaysia. Following the PRISMA Statement (Preferred Reporting Items for Systematic Reviews and Meta-Analyses), a systematic review was conducted with a particular focus on three main groups of the Orang Asli in Peninsular…

Purpose: This study examined two markers of language impairment (LI) in a single experiment, testing sentence imitation and grammatical morphology production using an imitation task with masked morphemes. One goal was to test predictions of the morphological richness account of LI in Czech. We also tested the independent contributions of language…

A lack of familiarity with the lexical, grammatical, and discursive features associated with academic language presents comprehension challenges for many adolescent readers, especially those with still-developing English language skills. Although many studies focused on reading comprehension in content areas, the prevalent use of standardized…

Purpose: In spite of improvements in language outcomes for children with hearing loss (HL) arising from cochlear implants (CIs), these children can falter when it comes to academic achievement, especially in higher grades. Given that writing becomes increasingly relevant to educational pursuits as children progress through school, this study…

Current models of the affinity between syntax and vocabulary are complex and recognize the contribution of bootstrapping and computational processes. To date, the mutual facilitation between these two constructs over time has not been studied in second language (L2) school children. The present study investigated longitudinally the direction and…

New linguistic information must be integrated into our existing language system. Using a novel experimental task that incorporates a syntactic priming paradigm into artificial language learning, we investigated how new grammatical regularities and words are learned. This innovation allowed us to control the language input the learner received,…

This dissertation places case, agreement and Voice phenomena in syntax. It argues that the derivation is driven by so-called derivational features, that is, structure-building features (Merge) and probe features (Agree) (Heck and Muller 2007 and Muller 2010; see also Chomsky 2000, 2001). Both types are essential in deriving case and agreement in…

Understanding the changes in our language abilities along the lifespan is a crucial step for understanding the aging process both in normal and in abnormal circumstances. Besides controlled experimental tasks, it is equally crucial to investigate language in unconstrained conversation. I present an information-theoretical analysis of a corpus of…

When threatened with ostracism, children attempt to strengthen social relationships by engaging in affiliative behaviors such as imitation. We investigated whether an experience of ostracism influenced the extent to which children imitated a partner's language use. In two experiments, 7- to 12-year-old children either experienced ostracism or did…

This article reviews prominent research on non-English-speaking children's extramural acquisition of English through digital media, and examines the understudied scenario of possible effects of such second language (L2) English input on domestically dominant but globally small first languages (L1s), with Icelandic as the test case. We outline the…
