Parity is one source of automatic reinforcement that increases the probability of verbal behavior that conforms to models provided by the verbal community. Parity as a conditioned reinforcer could explain the acquisition of grammar in the absence of direct, explicit reinforcement. This possibility has been explored in previous research on…

This paper reviews evidence for and against imitation as a factor in the acquisition of syntax. It is concluded that the effects of imitation of children's speech are too pervasive to be dismissed as irrelevant. An important question is how a child extracts grammatical information from imitated sequences. (CHK)

Investigates a strategy for language acquisition adopted by one child and the usefulness of imitation in supporting that strategy. Examination of recordings made of naturally occurring conversations between the child and his parents indicated that he exploited imitation fully in order to acquire language. Imitative utterances surpassed spontaneous…

Comparison of 32 children (ages 5-7) with specific language impairments (SLI) and normally developing children matched for either age or language development found that the SLI children, unlike either control group, performed significantly better for morpheme production tasks in an imitation instruction condition than in a modeling condition.…

A longitudinal study examining the role of imitation on children's lexical acquisition is discussed here. Findings did not support the view that imitation may enable new lexical items to be acquired, and it is noted that other functions of imitation in language acquisition should be explored. (CHK)

This study compared relative effectiveness of imitative treatment and conversational recast treatment in 7 children (ages 55-79 months) with language impairment and 7 controls. Target acquisition was faster under conversational recast treatment for both groups. Language-impaired children learned grammatical structures as efficiently as…

A structured discourse strategy, employing child echoic imitations and adult expansion, was used to teach five autistic preschool children two-term semantic relations. The strategy increased the children's initial spontaneous imitations of two-term relations. Following the imitation increase, spontaneous productions of the two-term relations…

Presents methodological and factual analyses of children's use of imitative speech as a strategy in language acquisition. The impact of conversational interactions and picture-story books on the speech of one girl aged 20 to 32 months is demonstrated. Four methodological problem areas are analyzed. (Author/RH)

Describes a study of three infants whose parents presented vocal models for the infants to imitate. Parents presented vocal models both with and without social praise. Infants showed systematic increases in matching after praise was introduced. Nonmatching vocalizations did not increase with introduction of praise. Findings demonstrate generalized…

Imitation in the speech of the child serves at least three functions in the development of linguistic competence. Imitation provides auditory feedback for phonological and morpho-syntactic accuracy, produces a model for verification and/or clarification by speakers, and "makes time" for the processing and acquisition of information. Beyond these…

A question of both theoretical and practical importance for the study of phonological development is whether there is a difference in the status of productions rendered spontaneously by the child and those repeated by the child after either an adult model or his own production. The relevant theoretical questions are: (1) Are all the child's…

Thirteen subjects (aged 5:6 to 6:6) with language disorders were given elicited imitation and spontaneous language tasks, and their performance was compared among and within subjects. The two procedures produced significantly correlated results for some children but not for others. Analysis of specific syntactic forms also produced variable…

Approximately 1,500 published and unpublished books and articles are listed in this bibliography on the broad area of observational learning in children which includes modeling, imitation, and vicarious conditioning. The majority of sources listed are dated from the 1960's and 1970's although some date as far back as the 1930's. Research in such…

Three discourse-related formal aspects of model-imitation pairs were analyzed longitudinally in successive samples from two Hungarian children. Results revealed an unbroken developmental trend leading to lexically coherent conversational replies and that imitation aided the children in learning the lexicon, making phonological approximations of…
