The hypothesis that impoverished language experience affects complex sentence structure development around the end of early childhood was tested using a fully randomized, sentence-to-picture matching study in American Sign Language (ASL). The participants were ASL signers who had impoverished or typical access to language in early childhood. Deaf…

The goal of this paper is to tease apart two approaches to the source of children's consistent scope assignment in negative sentences containing logical connectives: the Semantic Subset Principle and the Semantic Subset Maxim. Previous developmental work has observed that four- to six-year-old children across languages have difficulty with…

We analysed both structural and functional aspects of sentences containing the four adverbials "after", "before", "because", and "if" in two dense corpora of parent-child interactions from two British English-acquiring children (2;00-4;07). In comparing mothers' and children's usage we separate out the…

Adults find negative sentences difficult to process, but an informative context can facilitate processing substantially, suggesting that much of this difficulty may come from the pragmatics of negation. Are children sensitive to the pragmatics of negation as well? Although children perform poorly on many tests of negation comprehension, we argue…

Children have difficulty comprehending novel verbs in the double object dative (e.g., "Fred blicked the dog a stick") as compared to the prepositional dative (e.g., "Fred blicked a stick to the dog"). We explored this pattern with 3 and 4 year olds (N = 60). In Experiment 1, we replicated the documented difficulty with the…

The phenomenon of regularization -- learners imposing systematicity on inconsistent variation in language input -- is complex. Studies show that children are more likely to regularize than adults, but adults will also regularize under certain circumstances. Exactly why we see the pattern of behaviour that we do is not well understood, however.…

It is a common finding across languages that young children have problems in understanding patient-initial sentences. We used Tagalog, a verb-initial language with a reliable voice-marking system and highly frequent patient voice constructions, to test the predictions of several accounts that have been proposed to explain this difficulty: the…

Children with specific language impairment (SLI) demonstrate consistent comprehension problems. The present study investigated whether these problems are driven primarily by structural complexity or length. A picture-sentence matching task was presented to 30 children: (1) 10 children with SLI, (2) 10 comprehension-matched children with typical…

An experimental study investigating the interaction of linguistic complexity and performance in child language acquisition tests the hypothesis that children learning a first language acquire relatively complex sentences somewhat later than less complex sentences. In one of three tests, the subjects, 44 children aged 3.6 to 6 years, were presented…

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 of children's structuring of complex sentences requiring mood choices is reported. The objectives were to provide data for an understanding of sentence construction problems and to form a better idea of the acquisition of the intrinsic linguistic contrasts in the Spanish modal system. (MSE)

The purpose of the study was to apply various quantitative and qualitative indices of grammatical complexity proposed by Hunt (1965) to written language samples of hearing impaired students. Hunt studied grammatical structures of normal students at three grade levels, and found that the minimal terminal syntactic unit, or T-Unit, more reliably…

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)

The complexity of language of four, five, and six year old children was examined in a psycholinguistic study that attempted to differentiate the characteristics of sentences that were difficult for children to comprehend from those which were easy, and to discover whether children used a subject-verb-object (S-V-O) language strategy to interpret…

A study examining the initial stages in the acquisition of the conditional system is reported. The objective was to discover how morphological productivity is related to the child's comprehension of the semantics of individual conditional types. Schachter's model of reality and unreality conditionals was used as a framework. Eight middle class,…
