This study explored the impact of a caregiver training intervention on caregivers' use of individually selected facilitative language techniques (FLTs) with their children (ranging from 14 to 27 months of age) who were deaf or hard of hearing. In addition, the study sought to identify real-time relationships between caregiver input and child…

Words that describe sensory perception give insight into how language mediates human experience, and the acquisition of these words is one way to examine how we learn to categorize and communicate sensation. We examine the differential predictions of the typological prevalence hypothesis and embodiment hypothesis regarding the acquisition of…

For shared book reading to be effective for language development, the adult and child need to be highly engaged. The current paper adopted a mixed-methods approach to investigate caregiver's language-boosting behaviours and children's engagement during shared book reading. The results revealed there were more instances of joint attention and…

Child-directed speech has long been known to influence children's vocabulary learning. However, while we know that caregiver utterances differ from those directed at adults in various ways, little is known about any differences in the lexical properties of child-directed and adult-directed utterances. We compare over half a million word tokens…

Purpose: This study included two parts: a descriptive study followed by an integrative review. The purpose of the study was to converge finding from the descriptive study and summarize relevant findings from existent literature to identify potential culturally responsive early language and literacy intervention strategies for Native American…

Parents assessed the development of 12,081 two- to six-year-old children with Autism Spectrum Disorder (ASD) quarterly for three years on five subscales: combinatorial receptive language, expressive language, sociability, sensory awareness, and health. Longer duration of time spent with an adult actively involved in the same activity (termed here…

It is known that infant-directed speech (IDS) plays a key role in language development. Previous research, however, has also identified significant variability across societies in terms of how often IDS occurs. For example, some studies report very little IDS in non-western, small-scale societies -- including children growing up in small-scale…

A key question in developmental research concerns how children learn associations between words and meanings in their early language development. Given a vast array of possible referents, how does the child know what a word refers to? We contend that onomatopoeia (e.g. "knock," "meow"), where a word's sound evokes the sound…

The primary purpose of the current pilot study was to test the effects of an adapted and collaborative intervention model with a systematic teaching approach on Latina Spanish-speaking caregivers' use of "EMT en Español Para Autismo" strategies with their young children on the autism spectrum. A multiple baseline across behaviors single…

The study adopts a multimodal perspective, looking at adults' use of gestures in variation sets (VS; i.e. sequences of partial self-repetitions occurring in successive utterances of varying form) addressed to Spanish-learning toddlers in adult-child interactions. We seek to address the following question: Do adults make simultaneous use of VS and…

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…

Most language use is displaced, referring to past, future, or hypothetical events, posing the challenge of how children learn what words refer to when the referent is not physically available. One possibility is that iconic cues that imagistically evoke properties of absent referents support learning when referents are displaced. In an…

Joint Attention (JA) and Supported Joint Engagement (Supported JE) have each been reported to predict later language development in typically developing (TD) children and children with Autism Spectrum Disorder (ASD). In this longitudinal study including 33 TD children (20 months at V1) and 30 children with ASD (33 months at V1), the contributions…

Language development can be framed as the process of learning how to mean (Halliday, 1975). From this perspective, the role of communicative function is central to the language-learning process with development being guided by interaction with experienced others. In the current study, we present a detailed analysis of the communicative functions…

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…
