The team of the Unit of Phoniatrics and Logopedics of the Ain Shams University Clinic in Cairo, Egypt, has worked for three and half decades to spread awareness of child language disorders. This involved publications to inform the public, as well as health care professionals, about the needs of children with delayed language, through description…

The phonetic characteristics of canonical babbling produced by Korean- and English-learning infants were compared with consonant and vowel frequencies observed in infant-directed speech produced by Korean- and English-speaking mothers. For infant output, babbling samples from six Korean-learning infants were compared with an existing English…

The early development of vocalic and consonantal production in Mandarin-learning infants was studied at the transition from babbling to producing first words. Spontaneous vocalizations were recorded for 24 infants grouped by age: G1 (0 ; 7 to 1 ; 0) and G2 (1 ; 1 to 1 ; 6). Additionally, the infant-directed speech of 24 caregivers was recorded…

Joanne Paradis' Keynote Article on bilingualism and specific language impairment (SLI) is an impressive overview of research in language acquisition and language impairment. Studying different populations is crucial both for theorizing about language acquisition mechanisms, and for practical purposes of diagnosing and supporting children with…

Children find object relative clauses difficult. They show poor comprehension that lags behind production into their fifth year. This finding has shaped models of relative clause acquisition, with appeals to processing heuristics or syntactic preferences to explain why object relatives are more difficult than subject relatives. Two studies here…

This research aims to develop instruments to assess language development in under-3s and the adult interventions that support it. After an extensive literature search, observations were conducted in 17 groups of children spread over two day-care centres. In total 42 children were observed during a 30-minute slot and 25 adults during a half day.…

We investigated Early Head Start home visitors' use of evidence-based practices and the effectiveness of a web-based system to support these practices. Home visitors learned to use 3 evidence-based practices: (a) frequent assessment of children's early communication for screening and progress monitoring, (b) 2 home-based language promoting…

The study examines strategies multilingual children use to interpret grammatical relations, focusing on their two primary languages, Lajamanu Warlpiri and Light Warlpiri. Both languages use mixed systems for indicating grammatical relations. In both languages ergative-absolutive case-marking indicates core arguments, but to different extents in…

Although emerging evidence suggests that parental behavior is related to the development of child executive functioning (EF), the mechanisms through which parenting affects child EF have yet to be investigated. The goal of this study was to examine the potential mediating role of child language in the prospective relation between maternal autonomy…

A formative experiment investigated how two strategies aimed at increasing the quality and quantity of language interactions could be integrated into a preschool classroom. Strategies for enriching language interactions were introduced during book sharing, semi-structured group activities, and mealtimes. Mixed methods revealed factors that…

Contexts of limited input such as trilingual families where a language is not spoken in the wider community but only by a reduced number of speakers in the home provide a unique opportunity to examine closely the relationship between a child's input and what she learns to say. Barnes reported on the relationship between maternal input and a…

This study examines literacies practiced in bilingual households located in emerging communities along the Texas-Mexico border known as border colonias. Drawing on theoretical notions of space as geographic and temporal, the simultaneity of global and local forces at work in colonias, and expressions of agency that are "in between"…

The purpose of the study was to evaluate the language status of 120 young, Latino dual language learners living in poverty in the United States. Maternal language input and home language and literacy environments were examined with regard to language development at 24 and 36 months. Results suggested that even when combining English and Spanish…

This study is an investigation of the acquisition of existential constructions (ECs) in English and in Spoken Arabic. It is the first of its kind in that it examines the acquisition of the pieces and the features that form ECs; namely, existential "there," the copula, definiteness, and agreement for English and existential "fii," definiteness,…

Recent evidence from adult pronoun comprehension suggests that semantic factors such as verb transitivity affect referent salience and thereby anaphora resolution. We tested whether the same semantic factors influence pronoun comprehension in young children. In a visual world study, 3-year-olds heard stories that began with a sentence containing…
