Monolingual children identify referents uniquely in gesture before they do so with words, and parents translate these gestures into words. Children benefit from these translations, acquiring the words that their parents translated earlier than the ones that are not translated. Are bilingual children as likely as monolingual children to identify…

In this preregistered, longitudinal study of early code-switching, 34 US-born, Spanish-English bilingual children were recorded with a bilingual family member at 2;6 and 3;6, in Spanish-designated and English-designated interactions. Children's Spanish and English expressive vocabulary and their exposure to code-switching were measured through…

In this study we evaluated the predictive validity of conceptual scoring. Two independent samples of Spanish-speaking language minority preschoolers (Sample 1: N = 96, mean age = 54.51 months, 54.3% male; Sample 2: N = 116, mean age = 60·70 months, 56.0% male) completed measures of receptive, expressive, and definitional vocabulary in their first…

In this study, monolingual (English) and bilingual (English/Spanish, English/Urdu) five- and six-year-old children completed a grammaticality judgment test in order to assess their awareness of the grammaticality of two types of syntactic constructions in English: word order and gender representation. All children were better at detecting…

This study evaluated the development of vocabulary knowledge over the course of two academic years, beginning in preschool, in a large sample (N = 944) of language-minority children using scores from single-language vocabulary assessments and conceptual scores. Results indicated that although children began the study with higher raw scores for…

We report a longitudinal comprehension study of (long) passive constructions in two native-Spanish child groups differing by age of initial exposure to L2 English (young group: 3;0-4;0; older group: 6;0-7;0), where amount of input, L2 exposure environment, and socioeconomic status are controlled. Data from a forced-choice task show that both…

This paper examines the production of word-initial stops by two simultaneous trilingual sisters, aged 6;8 and 8;1, who receive regular input in Italian and English from multiple speakers, but in Spanish from only one person. The children's productions in each language were analyzed acoustically and compared to those of their main input providers.…

Considerable research has demonstrated that English-speaking children extend nouns on the basis of shape. Here we asked whether the development of this bias is influenced by the structure of a child's primary language. We tested English- and Spanish-speaking children between the ages of 1 ; 10 and 3 ; 4 in a novel noun generalization task. Results…

This study examines pragmatic differentiation in early trilingual development through a longitudinal analysis of language choice in a developing Tagalog-Spanish-English trilingual child. The child's patterns of language choice with different language users are analyzed at age 1 ; 10 and 2 ; 4 to examine: (1) whether evidence for pragmatic…

We present morphological analyses of verb inflections produced by 15 Spanish-speaking children (age range: 1;7 to 4;7) taken from longitudinal and cross-sectional samples of spontaneous speech and narratives. Our main observation is the existence of a dissociation between regular and irregular processes in the distribution of errors: regular…

Research on the development of efficiency in spoken language understanding has focused largely on middle-class children learning English. Here we extend this research to Spanish-learning children (n=49; M=2;0; range=1;3-3;1) living in the USA in Latino families from primarily low socioeconomic backgrounds. Children looked at pictures of familiar…

This study tests the widely cited claim that young simultaneous bilingual children reject cross-language synonyms in their earliest lexicons. First, the accuracy of the claim is examined, and then its adequacy as support for the argument that bilingual children do not have independent lexical systems in each language is considered. (JL)

Investigation of native English-speaking adults' and native Spanish-speaking children's acquisition of noun gender and its function in Spanish revealed significant differences in first- and second-language acquisition, suggesting a developmental progression in acquisition of noun gender for both groups.
