Typically-developing bilingual children often score lower than monolingual peers of the same age on standardized measures; however, research has shown that when assessed in more natural discourse contexts, bilinguals can perform similar to age-matched monolinguals in some language subdomains. This study investigated complex syntax production in…

Children's early grammatical constructions, e.g., SVO, exhibit a learning curve with cumulative verb types (CVT) increasing exponentially. According to Ninio (2006), the fact that learning curves, though nonlinear, can be modelled by a continuous regression suggests instant generalisation. Moreover, differences in initial verbs across children…

Usage-based theories of children's syntactic acquisition (e.g., Tomasello, 2000a) predict that children's abstract lexical categories emerge from their experience with particular words in constructions in their input. Because modifiers in English are almost always prenominal, children might initially treat adjectives similarly to nouns when used…

Introduction: It is well documented that preschoolers with DLD produce first instances of sentential complement clause sentences later than same-age peers with typical language. However, it remains unknown whether children with DLD are limited in their production of a variety of sentential complement clause sentences. Aims: Using a sentence…

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…

While there are always differences in children's input, it is unclear how often these differences impact language development -- that is, are developmentally meaningful -- and why they do (or do not) do so. We describe a new approach using computational cognitive modeling that links children's input to predicted language development outcomes, and…

Sentences that have more than one possible meaning are said to be syntactically ambiguous (SA). Because the correct interpretation of these sentences can be unclear, resolving SA sentences can be cognitively demanding for children, particularly with regards to inhibitory control (IC). In this study we provide three lines of evidence supporting the…

Like verbs, adjectives pose a challenge to the young word learner in that some -- like "red," "round," "rough," or "rectangular" -- map onto properties that are detectable through the senses, while others -- like "ready," "reasonable," or "required" -- express abstract…

This study explored the use of sophisticated vocabulary, complex syntax, and decontextualized language (including book information, conceptual information, past/future experiences, and vocabulary information) in teachers' instructional interactions with children during the literacy block in prekindergarten and kindergarten classrooms. The sample…

Cross-linguistically, statements and questions broadly differ in syntactic organization. To learn the syntactic properties of each sentence type, learners might first rely on non-syntactic information. This paper analyzed prosodic differences between infant-directed "wh"-questions and statements to determine what kinds of cues might be…

In Lebanese Arabic, lexical subjects may occur before or after verbs, but only before non-verbal predicates. Analysis of spontaneous language samples from 19 two-year-old children shows that postverbal (VS) and preverbal (SV) subjects emerge simultaneously. The youngest children displayed no VS-SV difference in frequency. A slight preference for…

This study explored responsive and linguistic parent input features during parent-child interactions and investigated how four input categories related to children's production of diverse, simple sentences. Of primary interest was parent use of responsive, simple declarative input sentences. Responsive and linguistic features of parent input to 20…

The goal of this study is to investigate the acquisition of causal relations with parce que "because" and temporal relations with quand "when" by children between age 3 and 5. We aim at identifying whether different discourse type, conversation and narration, allow children to use quand and parce que with different semantic…

We investigate Korean-speaking children's knowledge about clause-level constructions involving a transitive event -- active transitive and suffixal passive -- through corpus analysis and Bayesian modelling. The analysis of Korean caregiver input and children's production in CHILDES revealed that the rates of constructional patterns produced by the…

Verb-marking errors are a characteristic feature of the speech of typically-developing (TD) children and are particularly prevalent in the speech of children with Developmental Language Disorder (DLD). However, both the pattern of verb-marking error in TD children and the pattern of verb-marking deficit in DLD vary across languages and interact…
