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.

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…

Presents two probe recognition experiments investigating whether overt and null pronouns in American Sign Language (ASL) similarly reactivate their referents during online sentence comprehension. Both experiments indicated that an important link exists between spatial verb agreement and the ASL pronomial system and that nonreferent inhibition does…

A study examined aspects of the acquisition of spatialized morphology and syntax in American Sign Language (ASL) learned natively by deaf children of deaf parents. Children aged 2 to 8 were shown story books to elicit narratives, and the resulting use of verbs contained morphological forms not appearing in adult grammar. Analysis of the creative…
