This dissertation draws on both qualitative and quantitative approaches to investigate the linguistic practices of teachers and children who are learning Mandarin Chinese as a Heritage Language (CHL) in two dual immersion preschools in California. CHL children have been interpreted as novice members in local speech communities who actively explore…

Child speech is highly variable. The speech apparatus--the vocal tract, tongue, teeth, and vocal folds--develop at different rates for different children, which helps explain some of the variability in children's speech. For example, the ratio of the oral to pharyngeal cavities changes as children age, making it difficult to establish reliable…

The article by Amaral and Roeper (this issue; henceforth A&R) presents many interesting ideas about first and second language acquisition as well as some experimental data convincingly illustrating the difference between production and comprehension. The article extends the concept of Universal Bilingualism proposed in Roeper (1999) to second…

An area in need of study in child language acquisition is that of complex multilingual contexts in which there is little language separation by interlocutor or domain. Little is known about how multilingual children use language to construct their identities in each language or in both languages. Identity construction in monolingual contexts has…

As infant/toddler programs encounter growing diversity, they need to reenvision the impact they have on children and families in all areas of practice, from recruiting new enrollees to stocking classrooms to changing the ways adults interact with children and families with different languages and from different cultures. What happens on the first…

This paper examines the formal and functional properties of code-switching among Mexican-American children. Two formal types of code-switching, code-mixing and code-changing, are identified, and developmental patterns in their use are discussed. Two major functional types of code-switching are also differentiated. The first, situational…

This study continues a series of reports on the work of the team which has carried out a sociolinguistic survey of multilingual communities. This study deals with an early sample of the results of the St. Lucian survey, and in particular with the extent to which they provide support for the theoretical model of linguistic choice and change, and…

The linguistic interactions in the speech of bilingual children is systematically examined to determine their ability to differentiate between their two language systems. The speech samples of eighteen bilingual (Spanish-English) children aged two to six were examined for instances of deviation from the norms of the language of utterance due to…

Observation of child language development is just one way to study how language changes over time. Developmental psycholinguistics shares much common ground with historical linguistics and with studies of languages in contact and the evolution of pidgins and creoles. By studying the way language changes, this paper focuses on clarifying the…

The paper examines interpretive aspects of English non-uniformity among fifth and sixth grade Native Americans at Laguna Elementary School, Laguna, New Mexico. Speaker assessments of instances of uninflected "be" are ordered to form an implicational scale. The variability in the students' assessment pattern is compared to previous inter-ethnic…

Examines the phonetic characteristics of babbling by a pair of fraternal twins raised in a bilingual environment (English/Serbian). The study focused on the basic articulatory form of babbling, the impact of twinship on babbling patterns, and whether effects specific to one or another of the ambient languages could be observed. (30 references)…

Interviews with 108 Navajo children from bilingual first grade classes on Navajo reservations were recorded. Analysis of the interviews focused on phonological, grammatical, and lexical features that show a systematic variation within the speech of individuals or between individuals. Variable features were compared with background factors such as…

A three-year study of the linguistic and metalinguistic performance of forty Mexican-American children ranging in age from three to eleven years shows that it is useful to characterize the competence of the bilingual in terms of a unified system of rules, at least at one level of analysis. This paper explores some aspects of the grammatical…

A study of code-switching in a group of 35 Spanish-English bilingual third-graders is reported. The students' diary journal entries and writing assignments based on previous classwork are examined. Retelling of stories previously told by the teacher and the journal entries helped identify the kind of language used by students, the code-switching…

This study is a detailed analysis of the phonological development of Sylvia, a bilingual child, in her acquisition of American English and Brazilian Portuguese from the age of 1 year, 7 months to 3 years, 8 months. The study is divided into four stages: ages 1.7 - 1.9; 1.9 - 2.1; 2.1 - 2.3; and 2.3 - 2.8. Up to the age of 1.9, the same…
