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…

A proportion of children with visual impairments have specific reading difficulties that cannot be easily explained. This article reviews the data on problems with braille reading and interprets them from the framework of the temporal-processing deficit theory of developmental dyslexia.

Background: There are well-replicated findings that link poor development on a range of communication skills with increased behavioural problems. This paper examines this relationship in children with hearing loss. Method: One hundred and twenty children with hearing loss (67 boys, 53 girls) and 63 hearing children (37 boys, 26 girls) with a mean…

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…

Emerging phonotactic knowledge facilitates the development of the mental lexicon, as demonstrated by studies showing that infants use the phonotactic patterns of their native language to extract words from continuous speech. The present study provides a computational account of how infants might induce phonotactics from their immediate language…

In two studies we investigated 2-year-old children's answers to predicate-focus questions depending on the preceding context. Children were presented with a successive series of short video clips showing transitive actions (e.g., frog washing duck) in which either the action (action-new) or the patient (patient-new) was the changing, and therefore…

Middleverse de Español (MdE) is an evolving platform for foreign language (FL) study, aligned to the goals of ACTFL's National Standards and 2007 MLA report. The project simulates an immersive environment in a virtual 3-D space for the acquisition of translingual and transcultural competence in Spanish meant to support content-based and…

We tracked the developmental influences of exposure to French on developing English phonological awareness, decoding and reading comprehension of English-speaking at-risk readers from Grade 1 to Grade 3. Teacher-nominated at-risk readers were matched with not-at-risk readers in French immersion and English language programs. Exposure to spoken…

Learning to argue is a key academic purpose for both first and second language students. It has been claimed that computer mediated asynchronous text-based conferencing is a useful medium for developing argumentation skills (Andriessen, Baker, & Suthers, 2003). This paper reports on two research studies which explore this claim. One study focused…

Children use syntax as well as observations of events to learn verb meanings. This is known as syntactic bootstrapping. This dissertation investigated the origins and mechanisms of syntactic bootstrapping. Prior evidence suggested that two-year-olds, but not younger children, could use aspects of sentence structure to assign different…

Long before children learn language, they communicate with gestures, vocalizations, facial expressions, and body language. This is known as prelinguistic (prior to language) communication. Most children learn this type of communication without formal teaching, but children who are deaf-blind may need guidance to learn it. This publication…

All natural languages rely on sentence-level form-meaning associations (i.e., linking rules) to encode propositional content about who did what to whom. Although these associations are recognized as foundational in many different theoretical frameworks (Goldberg, 1995, 2006; Lidz, Gleitman, & Gleitman, 2003; Pinker, 1984, 1989) and are--at least…

Children often produce nonadult responses to sentences with the focus operator only, such as "Only the cat is holding a flag." For example, children often accept this sentence as a description of a situation in which a cat holds a flag and a duck holds both a flag and a balloon. One proposed analysis, by Paterson, Liversedge, Rowland & Filik…
