Previous research has revealed that distributional information obtained from child-directed speech could be informative for children when they are learning grammatical categories. Frequent frames are distributional units proposed by Mintz and explored by researchers in many languages with different typologies. This study investigated two…

The main goal of this tutorial is to promote the study of children with developmental language disorder (DLD) across different languages of the world. The cumulative effect of these efforts is likely to be a set of more compelling and comprehensive theories of language learning difficulties and, possibly, of language acquisition in general.…

Vulnerability of morphosyntactic production, including grammatical aspect, has been identified in at least some children with autism spectrum disorder (ASD) exposed to typologically different languages. However, Tovar et al. (2015) found strengths in comprehending grammatical aspect in English-exposed children with ASD, suggesting that the…

The paper shows that children acquiring Yemeni Ibbi Arabic4 (henceforth referred to as YIA) go through a stage equivalent to the Root Infinitive (RI) stage found in non-null subject languages in spite of the fact that YIA is a null subject and does not have an infinitive construction. Spontaneous speech of two YIA children (2;1-2;11) showed…

Syntactic structures are unobserved theoretical constructs which are useful in explaining a wide range of linguistic and psychological phenomena. Language acquisition studies how such latent structures are acquired by human learners through many hypothesized learning mechanisms and apparatuses, which can be genetically endowed or of general…

This paper presents an investigation of verb morphology in the spontaneous productions of three preschool Egyptian Arabic- (EA) speaking children with language impairment (LI) and a group of typically developing children. The typological characteristics of Arabic, such as its rich morphology, lack of infinitival form and complex verb system, make…

This study examines the morphosyntactic development, specifically verb morphology, of typically-developing Bangla-speaking children between the ages of two and four. Three verb forms were studied: the Present Simple, the Present Progressive and the Past Progressive. The study was motivated by the observations that reliable language-specific…

This article suggests a method to deal with cross-linguistic differences in children with Specific Language Impairment. The differences in vulnerable structures reflect typological properties of the surrounding language (e.g., Leonard 2014a, 2014b). This article adds a developmental perspective to the discussion by interpreting the vulnerable…

Heritage language speakers struggle in European classrooms with insufficient material provided for second language (SL) learning and assessment. Considering the amount of instruments and pertinent studies in English SL, immigrant students are better prepared than their peers in Romance language settings. This study investigates how factors such as…

Cross-linguistic research on the development of tense-aspect marking has revealed a strong effect of lexical aspect. But the degree of this effect varies across languages. Explanation for this universal tendency and language-specific variation is still an open issue. This study investigates the early emergence and subsequent development of four…

The relationship between written words and their pronunciation varies considerably among different orthographic systems, and these variations have repercussions on learning to read. Children whose languages have deep orthographies must learn to pronounce larger units, such as rhymes, morphemes, or whole words, to achieve the correct pronunciation…

The present study aims at testing the two dominant hypotheses regarding the development of inflections and other functional categories namely the "Structure-Building Model" and the "Continuity Hypothesis" within the generative theory. According to the first view, functional categories are entirely absent in children's early grammars, which contain…

Introduces this special issue of the journal and reports on new directions in the research that began with code switching, but increasingly has come to include other types of language contact phenomena. The articles in the issue report on analyses and explanations for a variety of outcomes in bilingual production. (Author/VWL)

It is possible to observe phonological innovations in Quechua B in purely linguistic terms, abandoning the use of dialects and subdialects. Isolect and lect are used instead. A particular speech form, with respect to a particular innovation, is an isolect in one of three possible ways: it lacks the innovation; it has the innovation as a variable…
