Purpose: Previous studies documenting longitudinal linguistic outcomes of children with specific language impairment (SLI) compared to their age peers focus on the property of obligatory finiteness marking in sentences across the age span of 5-18 years. This study evaluates tag questions as syntactically complex sentences that extend the demands…

Purpose: Although conversational recast treatment is generally efficacious, there are many ways in which the individual components of the treatment can be delivered. Some of these are known to enhance treatment, others appear to interfere with learning, and still others appear to have no impact at all. This study tests the potential effect of…

Taking into account the peculiarities of the Georgian language and integrating them into the teaching process remains an important task. Georgian is an agglutinative language, which means the existence of grammatical markers in word-forms related to certain semantic features. The system of the Georgian verb is unique in that it is based on…

The present study examines grammatical gender knowledge in offline production (gender marking on indefinite articles) and online gender processing (visual world paradigm) in adult second language (L2) learners of Norwegian with three different first languages (L1s): Greek, Russian, and Turkish. In particular, it investigates the role of the…

This dissertation is about the learnability of different generative, Separationist approaches to nominal morphosyntax. The core of my investigation is number, gender, and declension class, as manifested across nouns, adnominals (adjectives, numerals, demonstratives, and quantifiers), and articles. An extreme position would require that all of…

Background: Morphosyntactic problems are a core symptom of Developmental Language Disorder (DLD). In the Netherlands, children with (presumed) DLD can receive special care in language-focused treatment groups. The focus of these groups mainly lies in improving communicative intentions, vocabulary and phonology. Morphosyntactic skills receive less…

Children who speak non-standardized language varieties are at risk for both over- and under-referral to speech-language and special education services (e.g., Morgan et al., 2016; Pearson et al., 2014). Extensive research with bidialectal (Craig, 2016; Kohn et al., 2021) and bilingual (Goldstein, 2022; Paradis et al., 2021) children has shown the…

The present study aims at providing a descriptive account of the unaccusative verbs in Jordanian Arabic dialect (henceforth, JA) in terms of Transitivity. It also aims at presenting empirical evidence to prove that a split projection analysis is appropriate for unaccusative predicates in JA in light of the Minimalist Approach (Chomsky, 1995,…

Purpose: We investigated the effectiveness of a highly individualized morphosyntactic intervention using the SHAPE CODING™ system delivered at different dosages. Method: Eight children with developmental language disorder aged 8;0-10;10 (years;months) received 10 hr of explicit individualized intervention for morphosyntax delivered in 30-min…

Yamdena is an Austronesian language of eastern Indonesia. Although many language materials are available, the language has received very little scientific attention. In this article, I present the Yamdena corpus, which includes glossed legacy materials and original fieldwork. I also give an up-to-date introduction to Yamdena grammar, sketching its…

The current study examined early grammatical marking in a relatively understudied language, Mandarin, by using the Mandarin version of MacArthur-Bates Communicative Development Inventory. Two waves of data collection included 338 monolingual children (17-36 months; 143 female) at Time 1 and 308 children (32-55 months; 139 female) at Time 2 and…

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…

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…

This dissertation interrogates the representation of syntactic locality constraints, specifically intervention locality, within child grammar. Our focal point is the Intervention Hypothesis, which suggests that children are governed by a strict version of featural Relativized Minimality, leading to comprehension difficulties when partial featural…

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…
