This study aimed to establish whether 5- to 7-year-old children with developmental language disorder (DLD) have difficulties explaining actions in terms of intentions and if so, to elucidate the nature of such difficulties. Children with DLD and typically developing chronological age peers (TD group) participated in a production task designed to…

The results from a large-scale study on toddlers' language acquisition in European Portuguese are presented. Toddlers' lexical and grammatical competencies were assessed using the MacArthur-Bates Communicative Development Inventory: Words and Sentences. The results, based on 3012 reports completed by parents, indicate an increase in the lexical…

We elicited the production of various types of relative clauses in a group of German-speaking children with specific language impairment (SLI) and typically developing controls in order to test the movement optionality account of grammatical difficulty in SLI. The results show that German-speaking children with SLI are impaired in relative clause…

Children and adults follow cues such as case marking and word order in their assignment of semantic roles in simple transitives (e.g., "the dog chased the cat"). It has been suggested that the same cues are used for the interpretation of complex sentences, such as transitive relative clauses (RCs) (e.g., "that's the dog that chased…

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…

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"…

Negative sentences with epistemic modals (e.g., John "might" not come/John "can" not come) contain two logical operators, negation and the modal, which yields a potential semantic ambiguity depending on scope assignment. The two possible readings are in a subset/superset relation, such that the strong reading ("can…

This article reports on an experiment that examined the comprehension of transitive sentences in Czech children and its relationship to case marking, word order and information structure. A total of 107 Czech children aged 2;9-4;5 were tested for comprehension of noun-verb-noun sentences in which word order and given-new status of individual nouns…

Purpose: The current study used an intervention design to test the hypothesis that parent input sentences with diverse lexical noun phrase (NP) subjects would accelerate growth in children's sentence diversity. Method: Child growth in third person sentence diversity was modeled from 21-30 months (n = 38) in conversational language samples obtained…

The study examined linguistic flexibility of Hebrew-speaking students from middle childhood to adolescence compared with adults on tasks requiring them to alternate between different versions of varied linguistic stimuli. Lexical flexibility was tested by constructing different words with a shared root and a shared prosodic template;…

Replicates earlier studies and shows that children's ability to process syntactically well-formed sentences increases over the early school years. (Author/ED)

The purpose of this study was to explore whether 13 children with specific language impairment (SLI; ages 5;1-8;0 [years;months]) were as proficient as typically developing age- and vocabulary-matched children in the production of finite and nonfinite complement clauses. Preschool children with SLI have marked difficulties with verb-related…

We examine how attention to animacy information may contribute to children's developing knowledge of language. This research extends beyond prior research in that children were shown dynamic events with novel entities, and were asked not only to comprehend sentences but to use sentence structure to infer the meaning of a new word. In a 4 x 3…

THE PURPOSES OF THIS EXPERIMENT CONDUCTED IN THE TALLAHASSEE, FLORIDA PUBLIC SCHOOLS WERE (1) TO STUDY DIFFERENCES IN SENTENCE STRUCTURES AMONG STUDENTS VARYING IN CHRONOLOGICAL MATURITY AND MENTAL ABILITY WITHIN GRADES 4, 6, 8, 10, AND 12, AND (2) TO SEE IF AN INSTRUMENT COULD BE DEVISED TO EFFICIENTLY MEASURE SYNTACTIC MATURITY. THE INSTRUMENT…
