In a seminal study, Cameron-Faulkner et al. made two important observations about utterance-level constructions in English child-directed speech (CDS). First, they observed that canonical in/transitive sentences are surprisingly infrequent in child-direct speech (given that SVO word order is often thought to play a key role in the acquisition of…

Purpose: Typically developing multilingual children's speech may include mismatches and phonological patterns that are atypical in monolingual peers. One possible reason for mismatches is cross-linguistic transfer, when structures unique to one language are used while speaking another language. This study explored cross-linguistic transfer in…

Dual language learners are often underidentified for having language delays and may not receive services in their caregiver's primary language. This study explored how the language used during evaluations influenced the effectiveness of a brief intervention for children with mild language delays. By examining whether evaluation language impacts…

The relationship between emotion and language in children is an emerging field of research. To carry out this type of study, researchers need to precisely manipulate the emotional parameters of the words in their experimental material. However, the number of affective norms for words in this population is still limited. To fill this gap, the…

Children acquiring Japanese differ from those acquiring English with regard to the rate at which verbs are learned (Fernald & Morikawa, 1993). One possible explanation is that Japanese caregivers use verbs in referentially transparent contexts, which facilitate the form-meaning link. We examined this hypothesis by assessing differences in verb…

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…

The aim of this study is to set out to explore how children living in Polish-English transnational families in the UK develop "symbolic competence" and "symbolic power" in home settings. By focusing on the children's use of metaphor in family discourse when talking about the Moon, from a cognitive discursive perspective, this…

Children show a remarkable degree of consistency in learning some words earlier than others. What patterns of word usage predict variations among words in age of acquisition? We use distributional analysis of a naturalistic corpus of child-directed speech to create quantitative features representing natural variability in word contexts. We…

Many children learn language, in part, from the speech of non-native speakers who vary in their language proficiency. To investigate the influence of speaker proficiency on the quality of child-directed speech, 29 mothers who were native English speakers and 31 mothers who were native speakers of Spanish and who reported speaking English to their…

This study examines language mixing in 26 Spanish-English dual language learners over the course of their first year of preschool. The children's patterns of language choice while interacting in monolingual language contexts were analyzed at age 3;6 and 4;5 to examine: (1) whether the frequency of language mixing changed during the year; (2)…

Phonological selectivity is a phenomenon where children preselect which target words they attempt to produce. The present study examines selectivity in the acquisition of complex onsets and codas in English, and specifically in the acquisition of biconsonantal (CC) clusters in each position compared to triconsonantal (CCC) clusters. The data come…

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…

Purpose: Most educational assessments tend to be constructed in a close-ended format, which is easier to score consistently and more affordable. However, recent work has leveraged computation text methods from the information sciences to make open-ended measurement more effective and reliable for older students. This study asks whether such text…

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…

In teacher training curricula, books are presented as an ideal material for building and enriching young children's language. Yet, the routine of reading at home with children is hardly ever mentioned. In this chapter, the author proposes analyses of story-reading activities from a usage-based and first language acquisition perspective. The goal…
