In this study, 5-year-olds and adults described scenes that differed according to whether (a) the subject or object of a transitive verb represented an accessible or inaccessible referent, consistent or inconsistent with patterns of preferred argument structure, and (b) a simple noun was sufficient to uniquely identify an inaccessible referent.…

Although pragmatic deficits are well documented in autism, little is known about the extent to which grammatical knowledge in this disorder is deficient, or merely delayed when compared to that of typically developing children functioning at similar linguistic or cognitive levels. This study examines the knowledge of constraints on the…

This study examined metalinguistic awareness in children who were becoming bilingual in an immersion education program. The purpose was to determine at what point in emerging bilingualism the previously reported metalinguistic advantages appear and what types of metalinguistic tasks reveal these developmental differences. Participants were 124…

Tested comprehension of syntactic structures by presenting each structure with both plausible and implausible content. Results revealed that cognitive nonlinguistic factors were important for comprehension and that errors and reaction time increased with age. The minimal contribution of neuropsychological factors to this decline suggests that the…

To test to what extent children are aware of the differences between closed-class and open-class words, 104 children aged 3 to 5 years participated in a sentence repetition task. Children were more likely to repeat sentences correctly when the nonsense words functioned in open-class rather than in closed-class contexts. (Contains 20 references.)…

Two experiments were conducted to explore processing of relative clause structures by normal elderly adults. Four groups of subjects (aged 20-29 years, 60-69 years, 70-79 years, and 80-89 years) participated in a lexical decision task and a sentence repetition task. (19 references) (VWL)

School-aged, hearing-impaired children's propensity for incorporating complex syntax into the narratives and conversations they produced was investigated. Language samples containing both conversations and narratives in the form of story retellings were collected from seven subjects with moderate-to-severe hearing losses. (48 references) (VWL)

When elderly (70-89 years) and younger (30-49 years) adults imitated complex sentences, younger adults were more able to imitate accurately and correctly paraphrase sentences regardless of length, position, or type of embedded clause. Elderly adults were unable to imitate or paraphrase correctly long constructions, suggesting an age-related…
