The purpose of this study was to determine if children acquire grammatical case as a unified system or in a piecemeal fashion. In English language acquisition, many children make developmental errors in marking case on subject position pronouns (e.g., "Me" do it, "Him" like it). It is unknown whether children who produce…

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…

This study was designed to examine the strength of question types to obligate complete responses from children, and the effect of age and play context. Participants were typically developing children (mean ages 2;8, 3;4 and 4;7), who engaged in play with three speech-language pathologists in play contexts. Questions posed to the children were…

Background: Despite studies of how parent-child interactions relate to early child language development, few have examined the continued contribution of parenting to more complex language skills through the preschool years. The current study explored how positive and negative parenting behaviours relate to growth in complex syntax learning from…

The MacArthur-Bates Communicative Development Inventories (CDIs) are a widely used family of parent-report instruments for easy and inexpensive data-gathering about early language acquisition. CDI data have been used to explore a variety of theoretically important topics, but, with few exceptions, researchers have had to rely on data collected in…

The Maternal Interactive Beliefs Questionnaire (Johnston and Wong, 2002) assesses maternal beliefs about children's language development. This study investigated the psychometric properties of a Persian translation of this questionnaire. The translation followed the protocol of the World Health Organization. Psychometric properties were evaluated…

Although sentence repetition is considered a reliable measure of children's grammatical knowledge, few studies have directly compared children's sentence repetition performance with their understanding of grammatical structures. The current study aimed to compare children's performance on these two assessment measures, using a multiple-choice…

This study presents comprehension data from 6-7-and 8-10-year-old children as well as adults on the acceptability of null vs overt anaphoric forms (the demonstrative "hura" "that" and the quasipronoun bera "(s)he, him-/herself") in Basque, a language without true third-person pronouns. In an acceptability judgement…

Within English early childhood education, there is emphasis on improving speech and language development as well as a drive for outdoor learning. This paper synthesises both aspects to consider whether or not links exist between the environment and the quality of young children's utterances as part of their speech and language development and if…

This study investigates 3- to 5-year-old children's sensitivity to lexical, intonational and gestural information in the comprehension of speaker uncertainty. Most previous studies on children's understanding of speaker certainty and uncertainty across languages have focused on the comprehension of lexical markers, and little is known about the…

Child gender has been proved to affect toddlers'/children's language development in several studies, but its effect was not found to be stable across different ages or various aspects of language ability. The effect of gender on toddler's, children's and adolescents' language ability was examined in the present meta-analysis of ten Slovenian…

Research has shown that observing iconic gestures helps typically developing children (TD) and children with specific language impairment (SLI) learn new words. So far, studies mostly compared word learning with and without gestures. The present study investigated word learning under two gesture conditions in children with and without language…

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"…

Generative approaches to language have long recognized the natural link between theories of knowledge representation and theories of knowledge acquisition. The basic idea is that the knowledge representations provided by Universal Grammar enable children to acquire language as reliably as they do because these representations highlight the…

This study explores the developmental change of mother-child interactions in order to investigate which aspects of maternal behavior affect children's speech production. To this end, the interactions between 79 German-speaking mothers and their two- or five-year-old children were observed at two time points (12 months apart) and in two interactive…
