Early vocabulary development benefits from diverse lexical exposures within children's language environment. However, the influence of lexical diversity on children as they enter middle childhood and are exposed to multimodal language inputs remains unclear. This study evaluates global and local aspects of lexical diversity in three…

In a seminal study, Cameron-Faulkner et al. made two important observations about utterance-level constructions in English child-directed speech (CDS). First, they observed that canonical in/transitive sentences are surprisingly infrequent in child-direct speech (given that SVO word order is often thought to play a key role in the acquisition of…

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…

Research on "parentese," the acoustically exaggerated, slower, and higher-pitched speech directed toward infants, has mostly focused on maternal contributions, although it has long been known that fathers also produce parentese. Given recent societal changes in family dynamics, it is necessary to revise these mother-centered models of…

For much of the history of deaf education, spoken language bilingualism was not considered a viable goal. It was believed that given the challenges of meaningful auditory access, age-appropriate development in even one language would be daunting. However, implementation of universal newborn hearing screening during the early 2000s, along with…

This qualitative study involved American parents of deaf children who chose cochlear implants (CIs) and shared their perception of the lived experience of choosing Listening and Spoken Language (LSL) as a communication modality for their child. This study also involved the parents discussing their experiences with hearing professionals and how…

Using a meta-analytic approach, we evaluate the association between socioeconomic status (SES) and children's experiences measured with the Language Environment Analysis (LENA) system. Our final analysis included 22 independent samples, representing data from 1583 children. A model controlling for LENA[TM] measures, age and publication type…

Decentralized from decision-making processes, women have been placed at the periphery. Their silencing has been fundamental and intentional on the part of patriarchal institutions, for the sake of keeping them behind the discursive scene. To this effect, this paper examines the rebirth of women from prior states whereby they used to be denied the…

The linguistic input children receive across early childhood plays a crucial role in shaping their knowledge about the world. To study this input, researchers have begun applying distributional semantic models to large corpora of child-directed speech, extracting various patterns of word use/co-occurrence. Previous work using these models has not…

The first stage of combinatorial speech is better described as variable than uniform. Talk of variants obscures two different aspects of language (knowledge and use) and two different aspects of language development -- acquisition of the grammar (competence) and deployment of the grammar in speaking and listening (performance). Null subjects and…

Parents are often a good source of information, introducing children to how the world around them is described and explained in terms of cause-and-effect relations. Parents also vary in their speech, and these variations can predict children's later language skills. Being born preterm might be related to such parent-child interactions. The present…

This dissertation investigates when and how children figure out the force of modals, that is, when and how they learn that "can/might" express possibility, whereas must/have to express necessity. Learning modal force raises a logical "Subset Problem": given that necessity entails possibility, what prevents learners from…

This dissertation investigates the wide-ranging implications of a simple fact: language unfolds over time. Whether as cognitive symbols in our minds, or as their physical realization in the world, if linguistic computations are not made over transient and shifting information as it occurs, they cannot be made at all. This dissertation explores the…

This article explores the role of the reportative BIN in Yucatec Maya language acquisition and socialization among children aged 4 years and above, focusing on their interactions during pretend play. Building upon prior research on caregivers' strategic use of BIN, the study aims to elucidate the nuanced meanings and functions of the reportative…

In this paper, the authors report the findings of a narrative review of extant international research literature to propose a conceptual model for how young children's language is entangled with place. Educational policy, curriculum documents, and speech and language therapy assessments in England tend to frame children as placeless and treat the…
