The well-known sampling limitation of most longitudinal corpus data can be even more consequential in the study of morphosyntactic variation in child language. An analysis of caregiver input suggests that variable use in overlapping contexts may be hard to find by solely relying on corpus data collected under the sampling procedures that are…

This article presents a developmental pathway for the acquisition of morphosyntactic variation. Although there is abundant evidence that morphosyntactic variation is pervasive among adults, much less is known about how children acquire such variation. The literature thus far indicates that the pathway of development involves first producing only…

The first stage of combinatorial speech is better described as variable than uniform. Talk of variants obscures two different aspects of language (knowledge and use) and two different aspects of language development -- acquisition of the grammar (competence) and deployment of the grammar in speaking and listening (performance). Null subjects and…

Child language acquisition research has provided ample evidence of lexical frequency effects. This corpus-based analysis introduces a novel frequency measure shown to significantly constrain adult language variation, but heretofore unexplored in child language acquisition research. Among adults, frequent occurrence of a form in a particular…

Constraints on linguistic variation are consistent across adult speakers, yielding probabilistic and systematic patterns. Yet, little is known about the development of such patterns during childhood. This study investigates Spanish subject pronoun expression in naturalistic data from 154 monolingual children in Mexico, divided into four age…

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…

This dissertation examines Spanish Direct Object clitic pronouns in Argentine spoken Spanish of adults and children (ages 4;0-7;0). It concentrates on (Finite verb + Nonfinite verb) constructions that allow both pre-verbal (Proclisis) and a postverbal (Enclisis) clitic placement. Previous corpus studies have shown that lexical (finite verb),…

The present article examines the effect of variable input on the acquisition of plural morphology in two varieties of Spanish: Chilean Spanish, where the plural marker is sometimes omitted due to a phonological process of syllable final /s/ lenition, and Mexican Spanish (of Mexico City), with no such lenition process. The goal of the study is to…

Because of the syntactic differences between Spanish and Quechua, Quechua-speaking children must make major word order adjustments to learn the Peruvian Spanish taught in school. This study investigates whether the order or time sequence in which these changes are adopted reflects any general constraint, or is in any way predicted by a theory of…

This study tested a theory of null subject pronoun variation, based on a model of discourse connectedness, on the oral and written Spanish narratives of northern California Mexican-descent pre-adolescents. Results indicate the children with greatest depth of ties to the United States are less likely to use overt pronouns than children born in…

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…

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…
