Purpose: We measure typically developing monolingual child Spanish speakers' lexical development with a range of standard expressive and receptive tests. We also measure their comprehension of sentences with the existential quantifier "algunos" "some" to determine their abilities to generate "some, but not all" scalar…

Multiword units play an important role in language learning and use. It was proposed that learning from such units can facilitate mastery of certain grammatical relations, and that children and adults differ in their use of multiword units during learning, contributing to their varying language-learning trajectories. Accordingly, adults learn…

The present study examines the mechanisms of lexical case acquisition in Russian by two-to-five-year-old Russian monolingual (n = 54) and Russian-English bilingual children (n = 38). Participants performed a picture-based sentence completion task. Sentences were constructed to elicit production of real Russian words (n = 24) and nonce words (n =…

L3 acquisition is influenced by L1-L3 typology, learners' proficiency in those languages, and metalinguistic knowledge. However, the precise patterns of cross-linguistic influence (CLI) in L3 acquisition are still unclear. This study aimed to examine how the abovementioned factors affect learners' sensitivity to subject placement in L3 Italian. We…

This study examines the role of the lexicon and grammatical structure building in early grammar. Parent-report data in CDI format from a sample of 1151 German-speaking children between 1;6 and 2;6 and longitudinal spontaneous speech data from 22 children between 1;8 and 2;5 were used. Regression analysis of the parent-report data indicates that…

This article describes the lexical and syntactic development of written narratives in 24 deaf and hard-of-hearing (DHH) students aged between 8 and 18 and takes into account how their varying linguistic backgrounds may predict their written performance. All participants use spoken Swedish, but the study also considers their proficiency in Swedish…

Many connectives, such as "therefore" and "however," are used very frequently in the written modality. Their acquisition thus represents an important milestone in developing written language competences. In this article, we assess the development of competence with such connectives by native French speakers in a sentence-level…

Children show a remarkable degree of consistency in learning some words earlier than others. What patterns of word usage predict variations among words in age of acquisition? We use distributional analysis of a naturalistic corpus of child-directed speech to create quantitative features representing natural variability in word contexts. We…

The syntactic structure of sentences in which a new word appears may provide listeners with cues to that new word's form class. In English, for example, a noun tends to follow a determiner ("a"/"an"/"the"), while a verb precedes the morphological inflection [ing]. The presence of these markers may assist children in…

Cross-linguistically, monolingual children produce target-like inflected verbs much earlier than they can reliably distinguish between singular and plural subject-verb agreement morphology in comprehension (i.e. Johnson, V., J. de Villiers, and H. Seymour. 2005. "Agreement Without Understanding? The Case of Third Person Singular /s/."…

This study examined the development of and possible predictors of interrogative forms and functions in early childhood Mandarin. All the interrogatives drawn from the Early Child Mandarin Corpus (168 children 2;6, 3;6, 4;6, and 5;6) were analyzed. The main results indicated that (i) there were significant age effects in interrogative forms and…

Producing pronouns involves linguistic and social-cognitive knowledge because children must learn words and understand pronouns' changing referents. This study examined pronoun production longitudinally in young children with autism spectrum disorder (ASD; n = 15), whose social-cognition might impair pronoun use, and in typically developing (TD; n…

This study investigates the development of plural morphology in Jordanian Arab children, and explores the role of the predictability, transparency, productivity, and frequency of different plural forms in determining the trajectory that children follow in acquiring this complex inflectional system. The study also re-examines the development of the…

An in-depth examination of the acquisition of grammatical gender has not previously been conducted for Irish, an endangered indigenous language now typically acquired simultaneously with English, or as L2. Children acquiring Irish must contend with the opacity of the Irish gender system and the plurifunctionality of the inflections used to mark…

57 Polish-speaking children aged from 2;4, to 4;8 and 16 adult controls participated in a nonce-word inflection experiment testing their ability to use the genitive, dative and accusative inflections productively. Results show that this ability develops early: the majority of two-year-olds were already productive with all inflections apart from…
