The acquisition of question formation in spoken English and American sign language by two hearing children of deaf parents.

This longitudinal study investigated the acquisition of question formation in spoken English and American Sign Language (ASL) by two young hearing children of deaf parents. The linguistic environment of the children included varying amounts of exposure and interaction with normal speech and with the nonstandard speech of their deaf parents. This atypical speech environment did not impede the children's acquisition of English question forms. The two children also acquired question forms in ASL that are similar to those produced by deaf children of deaf parents. The two languages, ASL and English, developed in parallel fashion in the two children, and the two systems did not interfere with each other. This dual language development is illustrated by utterances in which the children communicated a sentence in spoken English and ASL simultaneously, with normal English structure in the spoken version and sign language structure in the ASL version.

Influence of certain language and communication environments in early childhood on the development of language in deaf individuals.

Four groups of deaf subjects between the age of 10-0 and 18-11 years were tested, employing the Test of Syntactic Ability, and the language subtests of the Stanford Achievement Test, in a study of the influence of early language and communication environment on later syntactic language ability. The groups, 18 subjects in each, were dichotomized by whether the parents were hearing or deaf and further subgrouped by the language ability of the parents if the parents were deaf, and by the amount and intensity of oral preschool training provided by the parents if the parents were hearing. The groups were labeled by the type of language used with them in infancy and early childhood: manual English, average manual, intensive oral, and average oral. Results showed significant superiority of the manual English group over the two oral groups on five of the six major test structures of the Test of Syntactic Ability. On the Stanford Achievement Test, the manual English group performed significantly better than the other three groups on all four subtests. The two manual groups performed significantly better than the two oral groups on every test measure employed.

Pronominalization in the language of deaf students.

Four hundred and eighty deaf students (age 10 to 18 years) and 60 hearing children (age eight to 10 years) were required to complete a stimulus sentence by selecting the appropriate pronoun from a list provided. The results indicated that subject and object case pronouns were easier than possessive adjectives, which were in turn easier than possessive pronouns and reflexives. Correct use of relative pronouns was the most difficult for both deaf and hearing subjects. Generalizations about the acquisition of the pronoun system must be limited, as it appeared that pronouns are mastered on a pronoun-by-pronoun basis rather than by categories (person, number, case) for both the deaf and hearing subjects.

Complement structures in the language of deaf students.

Four hundred and twenty-seven deaf students (age 10 to 19 years) and 60 hearing children (age eight to 10 years) judged the grammaticality of sample sentences which contained infinitival or gerundive complements. Results indicated improvement with increasing age for deaf students. Even the youngest hearing students consistently obtained higher scores than most of the deaf students. Although the function of the complement (as subject or object) did not make a difference in performance, the type of complement did. POSS-ing complements were easier than for-to complements. Verb type also influenced performance.

Some aspects of the verb system in the language of deaf students.

Approximately 480 deaf students (age 10 to 19 years) and 60 hearing students (age eight 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. The results indicated that deaf students have considerable difficulty with the verb system of English. This difficulty was most pronounced in the formation of tense and voice and in agreement in number and tense. A possible ordering for the acquisition of tense did emerge; from earliest to latest it is: simple past, future, present progressive, perfective, and passive. Improvement in grammaticality judgments appeared to come from an increase in recognition that incorrect sentences were ungrammatical.
