In their first few years, almost all children learn at least one language, though not equally well. Differences in the quantity, quality, sources, and variety of language inputs and conversation opportunities have a long-lasting effect. This article provides an overview of early language development and explains how talking with babies promotes…

Are thematic roles linked to verbs in young children as in adults or will children accept any participant in a given role with any verb? To assess early verb comprehension we used typicality ratings with adults, parental questionnaires, and Intermodal Preferential Looking with children. We predicted that children would look at named targets, would…

Past research has indicated that English-learning infants begin segmenting words from speech by 7.5 months of age (Jusczyk & Aslin, 1995). More recent work has demonstrated, however, that 7.5-month-olds' segmentation abilities are severely limited. For example, the ability to segment vowel-initial words from speech reportedly does not appear until…

Researchers have long noted that children's grammatical morphemes are variably produced, raising questions about when and how grammatical competence is acquired. This study examined the spontaneous production of determiners by two French-speaking children aged 1 ; 5-2 ; 5. It found that determiners were produced earlier with monosyllabic words,…

Research indicates that mothers scaffold the literacy skills of their children when jointly engaged in literacy-related activities in monolingual families (Tamis-LeMonda et al., 2001). Yet little is known about the linguistic environment of English language learners in the USA, a group at high risk for reading difficulties if they are only taught…

This dissertation investigates the acquisition of early verb inflection in child Slovenian from morphosyntactic and morphophonological perspectives. It centers on the phenomenon of root nonfinites, particularly the patterns of omission and substitution errors in verb inflection marking. It argues that every acquisition model needs to account…

Adolescents (N = 46; M = 12.46 years) who had previously participated in a longitudinal study of autobiographical memory development narrated their early childhood memories, interpreted life events, and completed a family history questionnaire and language assessment. Three distinct components of adolescent memory emerged: (1) age of earliest…

In this study, we use corpus analysis and computational modelling techniques to compare two recent accounts of the OI stage: Legate & Yang's (2007) Variational Learning Model and Freudenthal, Pine & Gobet's (2006) Model of Syntax Acquisition in Children. We first assess the extent to which each of these accounts can explain the level of OI errors…

The purpose of this study was to highlight the role of twin designs in understanding children's conversational interactions. Specifically, we (a) attempted to replicate the findings of genetic effects on children's conversational language use reported in DeThorne et al. (2008), and (b) examined whether the language used by examiners in their…

The availability of educational programming aimed at infants and toddlers is increasing, yet the effect of video on language acquisition remains unclear. Three studies of 96 children aged 30-42 months investigated their ability to learn verbs from video. Study 1 asked whether children could learn verbs from video when supported by live social…

This paper explores the language experiences of preverbal infants in Australian childcare centres with the aim of examining cultural regulation within the childcare context. Language is defined as a social and communicative act that is related to the development of voluntary action (Vygotsky 1962; Lock 1980; Leontiev 1994). The study uses…

This paper investigates informal learning, literacy and language development occurring in the home through exchanges between children of three to six years of age and their grandparents in Sylheti/Bengali-speaking families of Bangladeshi origin and monolingual English-speaking families of mixed ethnicity living in east London. A survey identifying…

This longitudinal assessment concentrated on the relation between the home literacy environment (HLE) and early language acquisition during infancy and toddlerhood. In study 1, after controlling for socio-economic status, a broadly defined HLE predicted language comprehension in 50 infants. In study 2, 27 children returned for further analyses.…

Infants and toddlers encounter numerous spoken story experiences early in their lives: conversations, oral stories, and language games such as songs and rhymes. Many adults are even surprised to learn that children this young need these kinds of natural language experiences at all. Adults help very young children take a step along the path toward…

Purpose: The validity of the Index of Productive Syntax (IPSyn; Scarborough, 1990) for children who speak African American English (AAE) was evaluated by conducting an item analysis and a comparison of the children's scores as a function of their maternal education level, nonmainstream dialect density, age, and clinical status. Method: The data…
