Across a diverse range of languages, children proceed through similar stages in their production of causal language: their initial verbs lack internal causal structure, followed by a period during which they produce causative overgeneralizations, indicating knowledge of a productive causative rule. We asked in this study whether a child not…

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…

Examines one kind of syntactic variation--variable subject pronoun presence with American Sign Language plain verbs. Focuses on narratives that occurred during conversations recorded as part of a larger study. (Author/VWL)

In an examination of the acquisition of the spatial syntax of American Sign Language (ASL), 43 children aged 3-10 years were given a range of comprehension and elicitation tests designed to analyze the subsystems involved in the corrrect use of ASL syntax. The subsystems were nominal establishment, verb agreement, and consistency of reference. The…

A study investigated acquisition of three independent yet simulatneously produced morphological systems in American Sign Language (ASL): the linguistic use of space, use of classifiers, and inflections for aspect, all information incorporated into the production of a sign. Subjects were 30 deaf children with severe or profound prelingual hearing…

Two possible iconic models of the acquisition of verb agreement in American Sign Language (ASL) are developed and contrasted with a third, morphological account of the acquisition of this aspect of ASL. Additionally, data from spontaneous conversation of deaf children who have deaf parents are considered to test these three models. An iconic model…
