Purpose: Talkers adapt their speech according to the demands of their listeners and the communicative context, enhancing the properties of the signal (pitch, intensity) and/or properties of the code (enhancement of phonemic contrasts). This study asked how mothers adapt their child-directed speech (CDS) in ways that might serve the immediate goals…

Inspired by research in language play and linguistic ethnography, this article examines children's language play in early childhood education and care (ECEC) as a locally situated generic practice created through children's semiotic repertoires. The article is based on video-recorded linguistic ethnographic fieldwork in a Danish day care centre.…

Objectives: The study aimed to investigate the predictive potential of language environment and vocal development status measures obtained through integrated analysis of Language ENvironment Analysis (LENA) recordings during the prelinguistic stage for subsequent speech and language development in Korean-acquiring children. Specifically, this…

Causation is a core feature of human cognition and language. How children learn about intricate causal meanings is yet unresolved. Here, we focus on how children learn verbs that express causation. Such verbs, known as lexical causatives (e.g., break and raise), lack explicit morphosyntactic markers indicating causation, thus requiring that the…

Purpose: Disfluencies can be classified as stuttering-like disfluencies (SLDs) or typical disfluencies (TDs). Dividing TDs further, stalls (fillers and repetitions) are thought to be prospective, occurring due to planning glitches, and revisions (word and phrase revisions, word fragments) are thought to be retrospective, occurring when a speaker…

This study focuses on parental use of parentese: the acoustically exaggerated, clear, and higher-pitched speech produced by adults across cultures when they address infants. While previous research shows that parentese enhances language learning and processing, it is still unclear what drives the variability in the amount of parental parentese…

Understanding the sequential associations between caregiver responsivity and child communication is pivotal for enhancing child outcomes and guiding effective interventions. This dissertation study evaluates the LENA Start™ on caregiver-child communication, focusing on sequential association between caregiver and child communicative behaviors.…

In this article, I advocate for an enriched view of children's linguistic input, with the aim of building sustainable and tangible links between theoretical models of language development and families' everyday experiences. Children's language experiences constrain theoretical models in ways that may illuminate universal learning biases. However,…

Purpose: Place and manner of articulation in American English-learning children's salient consonant-vowel-consonant-vowel (C[subscript 1]VC[subscript 2]V) target words (e.g., "baby," "bunny," and "cookie") were compared with their actual productions of these words. We hypothesized that target words with repeated place…

Cross-linguistic studies describing the syllabic structures of babbling productions agree on the high prevalence of the CV structure, but few have addressed the other types of syllables emerging during this pre-linguistic stage. However, studying the evolution of the distribution of syllabic structures during babbling would make it possible to…

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…

Modals (e.g., "can," "must") vary along two dimensions of meaning: "force" (i.e., possibility or necessity), and "flavor" (i.e., possibilities relative to knowledge [epistemic], goals [teleological], or rules [deontic] …). Comprehension studies show that children struggle with both force and flavor…

Children's language development can reflect the developmental process of children's cognition and social emotions. The present study focuses on preschool children's conversational competence and narrative competence, aiming at exploring developmental features of preschool children's pragmatic competence through analyzing data from self-built oral…

Background: The language that children are exposed to in their early years is enhanced by children's picture books. It is important to better characterise this input, and recent research has begun to explore corpora of narrative picture books. However, previous research has been restricted by methodological limitations that make it difficult to…

Word learning studies traditionally examine the narrow link between words and objects, indifferent to the rich contextual information surrounding objects. This research examined whether children attend to this contextual information and construct an associative matrix of the words, objects, people, and environmental context during word learning.…
