Background: Children's language abilities set the stage for their education, psychosocial development and life chances across the life course. Aims: To compare the efficacy of two preschool language interventions delivered with low dosages in early years settings (EYS): Building Early Sentences Therapy (BEST) and an Adapted Derbyshire Language…

Deaf Learners' Acquisition of fundamental lexical properties of high-frequency English verbs related to transitivity and intransitivity was examined, including the subtle distinction between unergative and unaccusative verbs. A 140-item sentence acceptability rating scale was used to assess this lexical knowledge in deaf college students at two…

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…

The fundamental difference hypothesis (FDH; Bley-Vroman, 1989, 1990) contends that the nature of language in natives is fundamentally different from the nature of language in adult nonnatives. This study tests the FDH in two ways: (a) via second language (L2) poverty-of-the-stimulus (POS) problems (e.g., Schwartz & Sprouse, 2000) and (b) via a…

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 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…

A competition model experiment is reported that investigated the sentence-processing strategies of English-speaking learners of Japanese and Japanese-speaking learners of English. Results indicated a correlation between learners' proficiency in Japanese and case-marker dependency in Japanese strings. (Contains 23 references.) (Author/LB)

Presents analyses of the use of the essential connectives "so,""because,""then," and "but" in narratives of children aged three to nine years. Connectives were used semantically, pragmatically, or, rarely, in error. Age changes were minimal. Structural complexity and elaboration improved throughout the…

Three papers from this issue of the Working Papers are provided here. "The Nesting Constraint in Child Language," by Patrick Alan Brogan, discusses a child's ability to perform complex, internally embedded sentences. It is hypothesized that difficulty stems from a child's limited short-term memory. "A Framework for Studying Kin Term…

By age two, a child begins to form complex sentences by joining two or more sentences or by embedding one sentence into another. Formation of conjoined structures is a simpler process and emerges earlier than that of embedding structures. This paper attempts to answer the following questions: (1) Do children produce or understand embedding…

Variations in the amount and nature of early language to which children are exposed have been linked to their subsequent ability (e.g. Huttenlocher, Haight, Bryk, Seltzer & Lyons, 1991; Hart & Risley, 1995). In three computational simulations, we explore how differences in linguistic experience can explain differences in word learning ability due…

A study is reported that investigated American children's use of subjects in early speech and compared this cross-sectional data to longitudinal data on Italian children's production of subjects. Twenty-one American children aged 1.10 to 2.8 years were recorded in mother-child interactions and grouped by mean length of utterance (MLU) produced.…

Papers in this volume include the following: "The Structural Sources of Verb Meaning" (Lila R. Gleitman); "Acquisition of Noun Incorporation in Inuktitut" (Shanley Allen, Martha Crago); "Why Do Children Omit Subjects?" (Paul Bloom); "Acquiring Language in a Creole Setting: Theoretical and Methodological…

The interlanguage hypothesis stresses that errors are a normal part of the language learning process. At the same time, in the view of many, the teacher has a responsibility to provide short cuts for the learner through appropriate corrective feedback. Conventionally, this has been taken to imply correction of expression by requiring repetition of…
