Smartphone use is ubiquitous in the lives of parents, and an emerging area of research is investigating how parental smartphone use during parent-child interactions affects children's language outcomes. Findings point toward negative outcomes in language development, but it is less clear what processes affect language outcomes. Gaze following,…

Deaf people use visual language and communication strategies naturally. Moreover, hearing people (both young children and adults) can also benefit from sign language and the visual strategies that deaf parents and teachers use with young children, an example of deaf gain. This paper will provide an overview of the concept of deaf gain, review…

Picture books inherently contain many parallel dimensions of information and serve as a rich source of input for children. However, studies of children's learning from picture books tend to focus on a single type of information (e.g., novel words). To better understand the learning-related potential of shared book reading, we examined 4.5- to…

Purpose: Past research shows that parentally responsive behavior toward the child positively influences language development in both neurotypical children and children with intellectual and developmental disabilities, including those with fragile X syndrome (FXS); however, most studies have focused exclusively on the mother--child relationship.…

There is resounding evidence of the existence of direct precursors of written language, most specifically phonological awareness, letter knowledge, vocabulary, and oral comprehension. The initial differences identified in the development of written language precursors are directly related to subsequent students' academic trajectories.…

Purpose: The aim of this study was to investigate the role of parental sensitivity in language and neurocognitive outcomes in children who are deaf and/or hard of hearing (DHH). Method: Sixty-two parent-child dyads of children with normal hearing (NH) and 64 of children who are DHH (3-8 years) completed parent and child measures of inhibitory…

The autism spectrum disorder phenotype varies by social and communication ability and co-occurring developmental, behavioral, and medical conditions. Etiology is also diverse, with myriad potential genetic origins and environmental risk factors. Examining the influence of parental broader autism phenotype--a set of sub-clinical characteristics of…

Whereas previous research has examined the role that parenting and home environments play in explaining the relation between family socioeconomic status and children's language development in the United States, relatively little is known about the associations between these constructs in other cultures. This study tested an integrated model of…

A Critical Discourse Analysis was used to examine the parents' social practice during shared storybook reading with young children (birth to eight-years-old). The methodology involved two phases: (1) educational databases were searched and (2) a template was developed and used to code the programmes' components and studies' research design.…

There is debate about how input variation influences child language. Most deaf children are exposed to a sign language from their non-fluent hearing parents and experience a delay in exposure to accessible language. A small number of children receive language input from their deaf parents who are fluent signers. Thus it is possible to document the…

Studies on the relationship between bookreading and language development typically lack data about which books are actually read to children. This paper reports on an Internet survey designed to address this data gap. The resulting dataset (the Infant Bookreading Database or IBDb) includes responses from 1,107 caregivers of children aged 0-36…

The authors systematically reviewed peer-reviewed studies done with LENA (Language ENvironment Analysis) technology, guided by three research questions: (a) What types of studies have been conducted, and with which populations, since the launch of LENA technology?; (b) What challenges related to use of LENA technology were identified?; and (c)…

Young children who hear more child-directed speech (CDS) tend to have larger vocabularies later in childhood, but the specific characteristics of CDS underlying this link are currently underspecified. The present study sought to elucidate how the structure of language input boosts learning by investigating whether repetition of object labels in…

Purpose: This study was designed to (a) identify sociodemographic, pregnancy and birth, family health, and parenting and child care risk factors for being a late talker at 24 months of age; (b) determine whether late talkers continue to have low vocabulary at 48 months; and (c) investigate whether being a late talker plays a unique role in…

Research on joint attention and language learning has focused primarily on cues requiring visual access. However, this narrow focus cannot account for the emergence of language among some congenitally blind children who develop language on the same developmental timescale as their sighted peers. Findings from this longitudinal, retrospective study…
