This paper reports a preliminary evaluation of the [Talkable] 10-week language learning programme. This training programme aims to help caregivers provide a rich language learning environment in a child's first 3 years of life through the provision of evidence-based information and practical strategies to promote language development delivered…

A grandmother attempts to teach her four-year-old granddaughter the multiplication tables using simple repetition, but they repeatedly start over at 'three fives'; the child keeps coming up with 'thirty-five'. We consider three possible explanations: self-perpetuating frequency of behavior, saliency of memory and Vygotsky's next or proximal zones…

In English, the sentence "Mary didn't eat pizza or sushi" is assigned the "neither interpretation" (both disjuncts must be false). In Mandarin Chinese, the equivalent sentence is assigned the at least one interpretation (at least one disjunct must be false). The cross-linguistic variation in the interpretation of negative…

Background: Bilingual children and children diagnosed with developmental language disorder (DLD) are characterized by reduced lexical-retrieval abilities. Few studies examined their joint contribution and the mechanisms underlying these effects in the lexical domain. Aims: To explore the joint effects of bilingualism and DLD by adopting a…

The maternal language input literature suggests that mothers with more education use a greater quantity and complexity of language with their young children compared to mothers with less education although race and socioeconomic status have been confounded in most studies because of small sample sizes. The current Family Life study included a…

For centuries, adults may have relied on pedagogies that promote rote memory for the learning of foreign languages through word associations and grammar rules. This contrasts sharply with child language learning which unfolds in socially interactive contexts. In this paper, we advocate an approach to study the social brain of language by grounding…

Minority languages in diglossic situations with a majority language face the danger of eventual loss of vitality. The first sign of this is when child language acquisition begins to erode. This dissertation investigates the intergenerational transmission of the Isan language, spoken in the Northeastern region of Thailand. While the Isan community…

In this article, we provide an overview of the last twenty years of research on Indigenous sign languages, deaf community sign languages, co-speech gesture, and multimodal communication in the Australian context. From a global perspective, research on sign languages and on the gestures that normally accompany speech has been used as the basis for…

Purpose: The purpose of this study is to characterize the local (utterance-level) temporal regularities of child-directed speech (CDS) that might facilitate phonological development in Spanish, classically termed a syllable-timed language. Method: Eighteen female adults addressed their 4-year-old children versus other adults spontaneously and also…

Purpose: The aim of this study was to examine the influence of caregivers' reports of family-related environmental confusion--which refers to the level of overstimulation in the family home environment due to auditory and nonauditory (i.e., visual and cognitive) noise--on the relation between child temperament and spoken language outcomes in…

A comprehensive theory of child language acquisition requires an evidential base that is representative of the typological diversity present in the world's 7000 or so languages. However, languages are dying at an alarming rate, and the next 50 years represents the last chance we have to document acquisition in many of them. Here, we take stock of…

Purpose: The aim of this study was to describe and explain changes in severity of speech sound disorder (SSD) and token-to-token inconsistency in children with high levels of inconsistency. Method: Thirty-nine children (aged 4;6-7;11 [years;months]) with SSDs and high levels of token-to-token inconsistency were assessed every 6 months for 2 years…

This dissertation presents a series of case studies concerned with whether the signal in a given set of measurements that we take in the course of linguistic inquiry reflects grammatical competence or performance factors. We know that performance and competence do not always covary, yet it is not uncommon to assume that measurements that we take…

Average differences in children's language abilities by socioeconomic status (SES) emerge early in development and predict academic achievement. Previous research has focused on coarse-grained outcome measures such as vocabulary size, but less is known about the extent to which SES differences exist in children's strategies for comprehension and…

Emerging audio technologies over the last decade have provided a new, unprecedented window into the everyday lives of infants and young children. These new approaches will allow us to begin to address longstanding questions about the nature of language experiences across languages, communities and situations and the role of these experiences in…
