With the proliferation of corpora, various syntactic analysis methodologies have been developed. However, syntactic analysis of Chinese sentences demands a theory that focuses more on word order and the interaction between content and function words, which is satisfied by pattern grammar theory. This study investigates the effectiveness of pattern…

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…

Purpose: Many state standards for elementary students require them to use complex syntax, and research has documented age-related increases in the production of complex utterances in elementary-aged school children. Speech-language pathologists who provide services for these children, however, need detailed information in order to plan curriculum…

Purpose: Production of complex syntax is a hallmark of later language development; however, most of the research examining age-related changes has focused on adolescents or analyzed narrative language samples. Research documenting age-related changes in the production of complex syntax in elementary school-aged children in conversational language…

This study modeled the effects of essay length and language features on the rated quality of second language (L2) expository and argumentative essays composed by Chinese university students. Latent variables were writing quality captured by essay scores, and lexical sophistication, syntactic complexity and cohesion, each of which was measured by…

Cocreating meaning in collaboration is challenging. Success is often determined by people's abilities to coordinate their language to converge upon shared mental representations. Here we explore one set of low-level linguistic behaviors, linguistic alignment, that both emerges from, and facilitates, outcomes of high-level convergence. Linguistic…

Natural language is known to play a crucial and specific role for children's learning in school mathematics. Not only does it carry special vocabulary, but subtle differences between natural languages may lead to surprising challenges, for instance, for learners who are not taught mathematics in their mother tongue. In this paper, the…

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…

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…

The use of subordination enables language users to achieve syntactic efficiency by allowing them to connect ideas in temporal/logical relation. Although the importance of subordination has been recognized in previous research on second language (L2) writing, it has been typically assessed with global indices that measure overall ratio of…

Little evidence has been reported for narrative-related difficulties for Chinese Mandarin-speaking school-age children with developmental language disorder (DLD). This study aimed to capture the indices from narratives that can differentiate Chinese children with and without DLD. Oral narrative and written narrative samples were collected from…

Communication Accommodation Theory (CAT) predicts that people adjust their language to match that of the other to promote comprehension, coordinate action, and facilitate harmonious relationships. CAT predicts that mothers will adjust their sentence length and complexity to match those of children. Prior tests of CAT confounded trait-like language…

We report findings from a corpus-based investigation of three young children growing up in German-English bilingual environments (M = 3;0, Range = 2;3-3;11). Based on 2,146,179 single words and two-word combinations in naturalistic child speech (CS) and child-directed speech (CDS), we assessed the degree to which the frequency distribution of CDS…

Objectives: Children with ADHD obtain lower scores than their peers on standardized language measures but less is known about their conversational language skills. We tested the ability of children with and without ADHD to monitor and repair their language during a conversation (social discourse) with a young adult. Methods: Forty-nine 9- to…
