This case study describes the use of a syntax intervention with two deaf children who did not acquire a complete first language (L1) from birth. It looks specifically at their ability to produce subject-verb-object (SVO) sentence structure in American Sign Language (ASL) after receiving intervention. This was an exploratory case study in which…

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…

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…

The role of verbs in American Sign Language (ASL) is investigated. Verb mutations in ASL are very different from the kinds of grammatical deformations that occur in English, and are different from those that occur in spoken languages as a whole. (HP)

This article discusses preliminary research that found that more than 90 percent of sentences written by children or for children contain verbs from 1 of 13 verb semantic-syntactic subsets. A strategy for assessing a child's knowledge of verbs from each subset is described, along with an assessment protocol. (Contains references.) (Author/CR)

Approximately 480 deaf students (age 10 to 19 years) and 60 hearing students (age 8 to 10 years) were asked to judge the grammaticality of sentences containing auxiliary verbs, of sentences where the verb had been deleted, and of sentences in which the verb tense was not marked. (Author)

Misinterpretations of the logical subject of infinitives by second language learners and prelingually deaf adults are compared with children's extension of the minimal distance principle during acquisition of infinitive complement structures and other research studies. Later acquisition of certain structure is explained in terms of the sentences'…

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…
