There is substantial evidence that children's apparent omission of grammatical morphemes in utterances such as "She play tennis" and "Mummy eating" is in fact errors of commission in which contextually licensed unmarked forms encountered in the input are reproduced in a context-blind fashion. So how do children stop making such…

A surprising comprehension-production asymmetry in subject-verb (SV) agreement acquisition has been suggested in the literature, and recent research indicates that task-specific as well as language-specific features may contribute to this apparent asymmetry across languages. The present study investigates when during development children acquiring…

The present article aims to shed light on the relationship between priming and creativity throughout Chinese children's ontogenetic development. It has been suggested that priming in naturalistic interaction occurs not as an exclusively implicit phenomenon. New methodological desiderata beyond traditional acceptability judgments have been…

Cross-linguistic studies have shown that typically developing children have difficulties comprehending non-canonical structures. These findings have been interpreted within the Relativized Minimality (RM) approach, according to which local relations cannot be established between two terms of a dependency if an intervening element possesses similar…

The process of the language acquisition of children is reflected in two aspects; language structure and pragmatic functions. Data from "The Longtime Tracing Oral Corpus of Typical Development Children" (one child; 2,367 sentences) are analyzed. This study examines the child's sentence final particle (SFP) "ba", in which we…

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…

Relative clauses have been implicated alternately as a strength and a weakness in the language of people with Williams Syndrome (WS). To clarify the facts, an elicited production test was administered to 10 people with WS (age 10-16 years), 10 typically developing children (age 4-7 years), and 12 typically developing adults. Nearly every WS…

This study explored the relationship between sentence disruptions and the length and complexity of sentences spoken by 26 typical children developing grammar. For most children, disrupted sentences tended to be longer and more complex than fluent sentences and the magnitude of the differences in length and complexity was positively correlated with…

Infants of 18 and 24 months acquiring English were tested in a preferential looking task on their ability to detect ungrammaticalities caused by manipulating a single function word in sentences. Infants heard grammatical sentences in which the determiner "the" preceded a target noun, as well as three ungrammatical conditions in which "the" was…

The article examines the child's ability to produce complex sentences with sections on a structural framework for complex language (clausal and nonclausal complexity), a developmental perspective (coordination of clauses, subordination of nominal, adverbial, and relative clauses), and applied considerations (evaluating and teaching complex…

A study was undertaken to investigate which of ten constructions are available to children of various ages for expressing conditionality. A modified sentence completion test based on use of the ten constructions was designed, field-tested, and administered individually to 20 students in each of five grades: kindergarten and grades two, four, six,…

Reports on children's mastery of one type of sentence structure which is derivationally complex and which has been shown to be psychologically complex as well, given the criteria of both comprehension and acceptability to the native speaker. (HOD)

Describes the longitudinal emergence of verb inflections as observed in the speech of four American English-speaking children emphasizing occurrence of inflections, their linguistic/non-linguistic contexts, and their conditional use. Discusses results in terms of sentence relations between verbs and other constituents and the semantics of verb…

Examined the role of animacy and pronouns as children ages 2 to 3 years acquired transitive construction. Participants learned two nonce verbs, one of which was modeled in several transitive sentence frames and the other in neutral sentence frames. Many children produced transitive sentences with the first verb, but only children near age 3…
