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…

Languages differ regarding the depth, structure, and syntactic domains of recursive structures. Even within a single language, some structures allow infinite self-embedding while others are more restricted. For example, when expressing ownership relation, English allows infinite embedding of the prenominal genitive "-s," whereas the…

In English, a sentence like "The cat didn't eat the carrot or the pepper" typically receives a "neither" interpretation; in Japanese it receives a "not this or not that" interpretation. These two interpretations are in a subset/superset relation, such that the "neither" interpretation (strong reading)…

Purpose: The purpose of the study was to examine the change in specific English microstructure features according to language ability in preschool Spanish-English dual language learners. Method: We collected English narratives from 22 Spanish-English dual language learners with typical language development (TD) and 22 Spanish-English dual language…

Previous studies using artificial languages suggest that sentence production can be guided by verb-specific as well as verb-general statistics present in the language input. Here we investigated whether the statistical properties of ongoing input in the speakers' native language systematically affected their sentence production. Three experiments…

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.…

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…

This article describes the development of new scales for assessing the status of a young child's language comprehension and production. Items and sections on the scales were included to reflect advances in research on language acquisition and impairment. The New Reynell Developmental Language Scales (NRDLS) were trialled on 301 children and then…

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;…

Measures of productivity and sentence organization are useful metrics for quantifying language development and language impairments in monolingual and bilingual children. It is not yet known what measures within and across languages are most informative when evaluating the language skills of bilingual children. The purpose of this study was to…

A promising source of insights into heritage language learning comes from the broader study of the role of input in language acquisition. We concentrate here on the possibility that qualitative differences in the proficiency of heritage and monolingual language learners can be traced to a qualitative difference in the input available to each…

AN INSTRUMENT FOR MEASURING LANGUAGE MATURITY SHOULD BE EASILY ADMINISTRABLE AND SCOREABLE AND SHOULD BE BASED ON VALID INDICES OF LANGUAGE MATURITY. A RECENT STUDY BY KELLOG W. HUNT SUGGESTED THAT THESE INDICES BE BASED ON A NEW SYNTACTIC UNIT, THE T-UNIT, CONSISTING OF 1 MAIN CLAUSE TOGETHER WITH ANY CLAUSES SUBORDINATED TO IT. COORDINATED MAIN…

Previous studies dealing with the age at which children acquire constituent order preferences have been in conflict. This study was designed to determine if children with normal language development demonstrate constituent order preferences as early as age three and one-half, or a mean age of four years, one month. To test this competency, an…

In recent years, T-unit analysis has been applied in second language research to characterize the syntactic nature of linguistic input and to assess the syntactic maturity of the learners' written production. This measure has been seen to provide an objective and reliable method of determining the overall complexity of language samples. However,…

Investigates the discourse coherence of school-aged children with Specific Language Impairment (SLI). Children with SLI were found to be significantly impaired in the areas of topic maintenance, event sequencing, explicitness, conjunctive cohesion, and fluency. Theoretical and clinical implications of the results are discussed. (Author/ER)
