Purpose: This study investigates the acquisition of aspect markers by Mandarin-speaking children with developmental language disorder (DLD) in comparison to typically developing aged-matched (TDA) children and typically developing younger (TDY) children through the aspect hypothesis (AH). Method: A sentence-picture matching task and a priming…

Associative anaphora refers to a discourse operation that links a definite determiner phrase (DP) to an antecedent that acts as an indirect referent of the definite DP. For example, in the sequence 'I bought a laptop. The keyboard was black', the definite DP 'the keyboard' is linked to 'a laptop', meaning 'the keyboard of the laptop'. The…

It has been reported for decades that preschool children (age 4-7) tend to assign non-adult-like interpretations for sentences with pre-subject exclusive only. This study reports findings from two experiments investigating (1) the effects of (in)congruent implicit questions in discourse contexts and (2) word order transformation on children's…

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…

This study examined the developmental trajectories of Arabic grammatical number in Arabic-English bilingual children. The samples consisted of 80 individuals (40 monolingual children residing in Jordan and 40 bilingual children residing in the USA), aged between 5 and 9 years. Data was collected through two tasks involving picture able objects and…

The purpose of this ethnographic case study was to study the language development of 4-year-old emergent bilinguals in a bilingual (Spanish/English) Head Start classroom with flexible language practices. Data were collected throughout the 10-month school year by visiting the classroom 2-3 times per week. Data include: field notes (observations and…

Purpose: The current study was designed to (a) describe average hourly Language Environment Analysis (LENA) data for preschool-age Spanish--English bilinguals (SEBs) and typically developing monolingual peers and (b) compare LENA data with mean length of utterance in words (MLUw) and total number of words (TNW) calculated on a selected sample of…

The current study examined preschool children's ability to evaluate the entailment patterns yielded by sentences containing two downward entailing (DE) operators, "every" and "no." When "no" precedes "every," the entailment pattern typically licensed by "every" changes, but only if "no"…

The world's languages draw on a common set of event components for their verb systems. Yet, these components are differentially distributed across languages. At what age do children begin to use language-specific patterns to narrow possible verb meanings? English-, Japanese-, and Spanish-speaking adults, toddlers, and preschoolers were shown…

Two-year-olds assign appropriate interpretations to verbs presented in two English transitivity alternations, the causal and unspecified-object alternations (Naigles, 1996). Here we explored how they might do so. Causal and unspecified-object verbs are syntactically similar. They can be either transitive or intransitive, but differ in the semantic…

Overview of current research on how children learn their native language before school. Implications to aid learning in school are discussed. (DR)

In a series of production and grammaticality judgment experiments, I investigated the status of children's non-adult questions with 2 auxiliary verbs, such as "What did the smurf didn't buy." Previous studies showed that these questions were produced primarily in negative contexts. In the first part of the study, I tested whether children produce…

The first phase of an ongoing study of communication in a naturalistic situation in which children talked to familiar children is described in this paper. The situation was one that encouraged pretend (or dramatic) play. Research was focused on (1) the amount of pretend play; (2) the amount of speech used for planning or managing the play; and (3)…
