Tailored support is crucial for deaf and hearing-impaired children to overcome learning difficulties, particularly during primary education. The absence of listening profoundly hinders the progression of the learning journey, as it plays a pivotal role in language acquisition. Employing assistive technology is one approach to address this issue in…

Language development is an important facet of early life. Deaf children may have exposure to various languages and communication modalities, including spoken and visual. Previous research has documented the rate of growth of English skills among young deaf children, but no studies have investigated the rate of ASL acquisition. The current paper…

Limited access to spoken and signed language is a worldwide phenomenon affecting deaf children. Language delay caused by impeded language acquisition has negative cascading effects on deaf children's learning and development. In the event of stymied language development, deaf students exhibit highly errored writing and commit errors unseen in the…

This article investigates the narrative skills of children acquiring Finnish Sign Language (FinSL). Producing a narrative requires vocabulary, the ability to form sentences, and cognitive skills to construct actions in a logical order for the recipient to understand the story. Research has shown that narrative skills are an excellent way of…

Engaged communication between mother and a child in their early developmental stages is one of the predictors of children's development of higher-order thinking skills. For deaf children, this engaged communication between mother and child hinges on the home language environment (HLE) being fully accessible to the child. This research uses…

Infants are born highly sensitive to the natural patterns found in languages. They use their perceptual sensitivity to acquire detailed information about the structure of languages in their environment. To date, most studies of infant perception and early language acquisition have investigated spoken/auditory languages and hearing infants (e.g.…

Children need to learn the demands of their native language in the early vocabulary development phase. In this dynamic process, parental multimodal input may shape neurodevelopmental trajectories while also being tailored by child-related factors. Moving beyond typically characterized group profiles, in this article, we synthesize growing evidence…

This case study describes the use of a syntax intervention with two deaf children who did not acquire a complete first language (L1) from birth. It looks specifically at their ability to produce subject-verb-object (SVO) sentence structure in American Sign Language (ASL) after receiving intervention. This was an exploratory case study in which…

Some studies have concluded that sign language hinders spoken language development for deaf and hard-of-hearing (DHH) children even though sign language exposure could protect DHH children from experiencing language deprivation. Furthermore, this research has rarely considered the bilingualism of children learning a signed and a spoken language.…

Most deaf children have hearing parents who do not know a sign language at birth and are at risk of limited language input during early childhood. Studying these children as they learn a sign language has revealed that timing of first-language exposure critically shapes language outcomes. But the input deaf children receive in their first language…

The hypothesis that impoverished language experience affects complex sentence structure development around the end of early childhood was tested using a fully randomized, sentence-to-picture matching study in American Sign Language (ASL). The participants were ASL signers who had impoverished or typical access to language in early childhood. Deaf…

This article is a critical review of a book by Sir William Wilde (better known as the father of Oscar Wilde) entitled "On the Physical, Moral, and Social Condition of the Deaf and Dumb" (1854). This book, which is based on the demographic and medical information that he collected from "deaf and dumb" people in the early 1850s,…

Deaf education officially began in Portugal in 1823, with Pedro Aron Borg, at the invitation of D. João VI and his daughter, D. Isabel. In Brazil, it began in 1857, when Édouard Adolfo Huet Merlo founded the first institution, with the consent of D. Pedro II. The Royal Institute for the Deaf-Mute and the Blind in Lisbon and the Imperial Institute…

The ability to associate different types of number representations referring to the same quantity (symbolic Arabic numerals, signed/spoken number words, and nonsymbolic quantities), is an important predictor of overall mathematical success. This foundational skill--mapping--has not been examined in deaf and hard-of-hearing (DHH) children. To…

Young children do not develop language skills by studying grammar and rules for forming sentences. Children's brains are wired to acquire language naturally; all they need is exposure. Many opportunities for language learning are lost to deaf children if they are not surrounded by other signers. In fact, the loss can be so severe that deaf and…
