Preschool teachers can best educate youngsters learning their home language and English by using children's primary language where possible, adopting effective practices for building English language skills, and involving families in supporting children's learning. This article surveys the growing body of research on improving preschool…

The present study investigates whether four- and six-year-old children use pragmatic competence as a criterion for learning from someone else. Specifically, we ask whether children use others' adherence to Gricean maxims to determine whether they will offer valid labels for novel objects. Six-year-olds recognized adherence to the maxims of…

Children's assignment of novel words to nameless objects, over objects whose names they know (mutual exclusivity; ME) has been described as a driving force for vocabulary acquisition. Despite their ability to use ME to fast-map words (Preissler & Carey, 2005), children with autism show impaired language acquisition. We aimed to address…

It is not well understood how grammar emerges in very-low-birth-weight (VLBW) children. The main aim of the present study was to gain information on the emergence of grammar in this group at 2; 0. The Finnish version of the Communicative Development Inventory was used to collect data from VLBW children ("N" = 156) and full-term controls…

This article addresses the effect of communicative activity on the use of language and gesture by school-age children. The present study examined oral narratives and explanations produced by children aged six and ten years on the basis of several linguistic and gestural measures. Results showed that age affects both gestural and linguistic…

Although it has been often hypothesized that children learn to produce new sound patterns first in frequently heard words, the available evidence in support of this claim is inconclusive. To re-examine this question, we conducted a survival analysis of word-initial consonant clusters produced by three children in the Providence Corpus (0 ; 11-4 ;…

To test general and specific processes of symbol learning, 4- and 5-year-old children learned three kinds of abstract associates for novel objects: words, facts, and pictograms. To test fast mapping (i.e., one-trial learning) and subsequent learning, comprehension was tested after each of four exposures. Production was also tested, as was…

Instructive feedback (IF) is a teaching strategy in which extra information is presented to a student during teaching trials for other target skills. Research has shown that when IF is utilized with students with disabilities, they acquire additional skills without additional instructional time (fewer trials and sessions), resulting in more…

Early in development, many word-learning phenomena generalize to symbolic gestures. The current study explored whether children avoid lexical overlap in the gestural modality, as they do in the verbal modality, within the context of ambiguous reference. Eighteen-month-olds' interpretations of words and symbolic gestures in a symbol-disambiguation…

Two studies investigated differences in the comprehension and production of words in 2-year-old children and adults. Study 1 compared children's speaking and understanding of the names of 12 novel objects presented over three weekly sessions. Study 2 tested adults' performance under similar training and testing conditions over two sessions. The…

This dissertation concerns the acquisition of the interaction between lexicosemantic properties of verbs and syntax, focusing on symmetrical and asymmetrical verbs in different syntactic structures. Based on linguistic evidence, it is shown that two conceptual categories, Mutuality and Number, interact to give rise to four event-types: Single…

A fundamental component of language acquisition involves organizing words into grammatical categories. Previous literature has suggested a number of ways in which this categorization task might be accomplished. Here we ask whether the patterning of the words in a corpus of linguistic input ("distributional information") is sufficient, along with a…

Purpose: There is considerable controversy regarding whether to use telegraphic or grammatical input when speaking to young children with language delays, including children with autism spectrum disorder (ASD). This study examined telegraphic speech use in parents of preschoolers with ASD and associations with children's spoken language 1 year…

Southern Peruvian Quechua is an indigenous language spoken primarily in rural communities in the Peruvian Andes. The language includes a syntactic construction, "-paq", that expresses purpose or function, thus providing an opportunity to trace how parents and children with little formal education express teleological concepts. The…

The goal of this study was to investigate the effect of Chinese-specific morphological awareness on vocabulary acquisition among young Chinese-speaking students. The participants were 288 Chinese-speaking second graders from three different cities in China. Multiple regression analysis and mediation analysis were used to uncover the mediated and…
