Two studies are discussed that were conducted to investigate the status of control principles in children's grammar. An attempt is made to characterize the children's grammar types in terms of Universal Grammar and to account for how the grammar types change. (35 references) (JL)

We present a set-theoretic model of the mental representation of classically quantified sentences (All P are Q, Some P are Q, Some P are not Q, and No P are Q). We take inclusion, exclusion, and their negations to be primitive concepts. We show that although these sentences are known to have a diagrammatic expression (in the form of the Gergonne…

Recent work in language and text has explored such broad functional categories as evidentiality and affect, and has examined their cross-linguistic occurrences and manifestations. This paper focuses on a single construction, explores its variations, and describes and explains its pragmatic and textual functions. This rare construction, exemplified…

A study investigated the differences made in the meaning of a passage in English by placing adverbial clauses before (preposing) or after (postposing) the verb. Examples are: "When the wolf arrived, he was picking apples"; "He was picking apples when the wolf arrived"; "While he was picking apples, the wolf arrived"; and "The wolf arrived while he…

Research in the active-passive verb relation has indicated that there is an interaction between syntactic form and verb semantics among children of preschool age. The present study examines the contribution of active-passive syntax and verb semantics to comprehension difficulty for preschoolers, 6-year-olds, 7-year-olds, and adults. An additional…

Two experiments measured the frequency of perceptual errors as a function of differential presupposition in descriptive sentences. More errors occurred when misrepresentation involved presupposition than when it involved the focused proposition. Several surface structures of English, in combination, increased the presuppositional strength of the…

An analysis of TH-roles in middle constructions (e.g., "this book reads poorly") responds to theories that the non-overtness of TH-roles in these constructions is attributable to syntactic suppression. It is argued that middle formation does not involve lexical operations that adjust a verb's argument structure, but rather involves two…

Many syntactic and semantic studies have focused on the distribution of closed-class lexical noun phrases (NPs) such as "her, herself, and each other." Recent work has demonstrated that many other NPs are also referentially dependent. A model-theoretic semantic analysis of a number of such referentially dependent NPs is presented. These…

Switch reference, in which certain clauses contain a signal indicating whether that clause has the same or a different subject, is examined in Mbya Guarani. It is found that most cases can be covered by a grammatical rule stated in terms of the grammatical subjects of the two clauses involved, yielding "same subject" and "different…

First language acquisition studies reveal that children overextend the minimal distance principle (MDP) during their acquisition of infinitive complement structures. The MDP dictates the interpretation of the logical subject of the infinitive in these structures and overrides marked lexical features such as subject control. Misinterpretations by…

Describes a study that examines the ability of children to identify given/new elements in passive and cleft forms in order to ascertain the relationship between syntactic and pragmatic acquisition. Results indicate that complete competence with these marked sentence forms does not occur universally until some time in adolescence. (SED)

Examines the role played by relative clauses in American Sign Language. (FL)

Includes sample forms used in the study to elicit students' compositions and examples of those compositions. (SW)
