We examined how noun frequency and the typicality of surrounding linguistic context contribute to children's real-time comprehension. Monolingual English-learning toddlers viewed pairs of pictures while hearing sentences with typical or atypical sentence frames ("Look at the…" vs. "Examine the…"), followed by nouns that were…

Previous studies have found correlations between parent input and child language outcomes, providing prima facie evidence for a causal relation. However, this could also reflect the effects of shared genes. The present study removed this genetic confound by measuring English vocabulary growth in 29 preschool-aged children (21 girls) aged…

We examined the size, content, and use of evaluative lexis by 26 English monolingual and 20 Spanish-English bilingual 30-month-old children in interaction with their mothers. We extracted the evaluative words, defined as words referring to cognition, volition, or emotion. Controlling for overall vocabulary skills as measured by the MacArthur-Bates…

In children acquiring various languages, the early mastery of determiners strongly predicts syntactic development. What makes determiners important is not yet clear as there is a linguistic controversy regarding their syntactic behaviour. Some consider determiners to be similar to adjectives and to modify common nouns, while others consider the…

The purpose of this study was to determine if children acquire grammatical case as a unified system or in a piecemeal fashion. In English language acquisition, many children make developmental errors in marking case on subject position pronouns (e.g., "Me" do it, "Him" like it). It is unknown whether children who produce…

Children's development of the functional category of articles can be explained in two ways. One approach assumes that children are equipped with innate knowledge of the category, while the other assumes that children's early articles are limited-scope formulae. Using Eisenbeiss's (2000) criteria for determining the status of DPs, developed for a…

English has a word-minimality requirement that all open-class lexical items must contain at least two moras of structure, forming a bimoraic foot (Hayes, 1995).Thus, a word with either a long vowel, or a short vowel and a coda consonant, satisfies this requirement. This raises the question of when and how young children might learn this…

Many sentences of adult English are analytic constructions, namely clauses with a matrix verb complemented by a dependent predicate that does not have an expressed syntactic subject. Examples are subject and object control, raising to subject or object, periphrastic tense, aspect and modality, copular predication and "do"-support. In…

Structural priming is a useful laboratory-based technique for investigating how children respond to temporary changes in the distribution of structures in their input. In the current study we investigated whether increasing the number of object relative clauses (RCs) in German-speaking children's input changes their processing preferences for…

Following the proposal that consonants are more involved than vowels in coding the lexicon (Nespor, Peña & Mehler, 2003), an early lexical consonant bias was found from age 1;2 in French but an equal sensitivity to consonants and vowels from 1;0 to 2;0 in English. As different tasks were used in French and English, we sought to clarify this…

Most evidence concerning cross-linguistic variation in noun bias, the preponderance of nouns in early expressive lexicons (Gentner, 1982), has come from comparisons of monolingual children acquiring different languages. Such designs are susceptible to a number of potential confounders, including group differences in developmental level and…

Purpose: Vocabulary assessment holds promise as a way to identify young bilingual children at risk for language delay. This study compares 2 measures of vocabulary in a group of young Spanish-English bilingual children to a single-language measure used with monolingual children. Method: Total vocabulary and conceptual vocabulary were used to…

Previous research has reported that bilingual children sometimes produce mixed noun phrases with "correct" gender agreement--as in "der dog" ("der" being a masculine determiner in German and the German word for "dog", "hund", being masculine as well). However, these could obviously be due to chance or to the indiscriminate use of a default…

This study focuses on a trilingual toddler's ability to differentiate her Tagalog, Spanish and English productions on phonological/phonetic grounds. Working within the articulatory phonology framework, the word-initial segments produced by the child in Tagalog, Spanish and English words at age 1;10 were narrowly transcribed by two researchers and…

Using a name-based categorization task, Nazzi found in 2005 that French-learning 20-month-olds can make use of one-feature consonantal contrasts between new labels but fail to do so with one-feature vocalic contrasts. This asymmetry was interpreted as developmental evidence for the proposal that consonants play a more important role than vowels at…
