This study investigated fast mapping in late-talking (LT) toddlers and toddlers with normal language (NL) development matched on age, nonverbal cognition, and maternal education. The fast-mapping task included novel object labels and familiar words. The LT group scored significantly lower than the NL group on novel word comprehension and…

This paper investigated the predictive ability of expressive vocabulary size and lexical composition at age 2 on later language and literacy skills from ages 3 through 11. Multivariate analysis of covariance was performed to compare 16 language and literacy outcomes between children with large expressive vocabulary size at 24 months (N = 1,073)…

The relation of social and linguistic input measures to early vocabulary development was examined in 30 low-income African American mother-infant pairs. Observations were conducted when the child was 0 years, 1 month (0;1), 0;4, 0;8, 1;0, 1;6, and 2;0. Maternal input was coded for word types and tokens, contingent responsiveness, and…

This study examined effects of lexical factors on children's spoken word recognition across a 1-year time span, and contributions to phonological awareness and nonword repetition. Across the year, children identified words based on less input on a speech-gating task. For word repetition, older children improved for the most familiar words. There…

In this study, 5-year-olds and adults described scenes that differed according to whether (a) the subject or object of a transitive verb represented an accessible or inaccessible referent, consistent or inconsistent with patterns of preferred argument structure, and (b) a simple noun was sufficient to uniquely identify an inaccessible referent.…

The cross-overs between monolingual-bilingual and typically atypically developing children are a goldmine for research on language development. The four permutations of language exposure and language abilities create "natural experimental conditions" for investigating the nature of the language capacity and how this is shaped by input in typical…

The purpose of this article is to examine the language of girls and boys between 8 and 30 months of age, using the Quebec French version of The MacArthur Communicative Development Inventories. The findings from this parental report measure confirm those of earlier research, which showed the linguistic superiority of girls over boys at a young age.…

The use of four types of psychological state words (physiological, emotional, desire, and cognitive) during mother-child play sessions at ages 3, 4, and 5 years was examined in 30 children diagnosed with delayed expressive language at 24-31 months and 15 age-matched comparison children with typical development. The children's mean length of…

In six analyses using the Child Language Data Exchange System known as CHILDES, we explored whether and how parents and their 1.5- to 5-year-old children talk about writing. Parent speech might include information about the similarity between print and speech and about the difference between writing and drawing. Parents could convey similarity…

The relationship between written words and their pronunciation varies considerably among different orthographic systems, and these variations have repercussions on learning to read. Children whose languages have deep orthographies must learn to pronounce larger units, such as rhymes, morphemes, or whole words, to achieve the correct pronunciation…

Describes a study which explored developmental changes in preschoolers' knowledge of the writing system. The children were asked to write four utterances without knowing the purpose of the request and without additional explanations. The purpose was to determine how early children's graphic responses in decontextualized situations have features of…

The aim of the present study was to investigate the grain size predominantly used by children learning to read and spell in Indonesian. Indonesian is an orthographically transparent language, and the syllable is a salient unit. Tasks assessing various levels of phonological awareness as well as letter knowledge, reading familiar words and…

Using nonword repetition tasks as an experimental approach with both adults and children has become quite common in the past 10 to 15 years for studying lexical learning and phonological processing (e.g., Bailey & Hahn, 2001; Gathercole, Frankish, Pickering & Peaker, 1998; Munson, Edwards, & Beckman, 2005; Storkel, 2001; Vitevich & Luce, 2005). In…

Personal event and fictional narratives are compared across 36 normal children in 2 language-ability (one high, one low) groups using episodic analysis. Findings suggest that narrative structures for personal event narratives and fictional stories may follow different developmental paths, and that differences in productive language abilities…

Investigation of the perception and production of English voiceless fricatives in normally developing monolingual 3- to 5-year-olds (N=12) partially supported the hypothesis that certain sound substitutions by older children are perceptually based substitutions, typified by poor discrimination, while others are phonetic substitutions--phonemic…
