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…

In this qualitative study, the author investigated nature as a context for language development. Participants included 15 toddlers and their caretakers who enrolled in a series of environmental education workshops on the topics of grass, butterflies, spiders, and leaves. Using field notes and photographs, the study sought to investigate elements…

English language learners (ELLs) bring a wealth of knowledge to science classrooms, yet often that knowledge is untapped by traditional instruction and assessment. As classrooms become increasingly diverse, it is critical to recognize the depth of understandings ELLs bring to classrooms to explain the scientific world around them. English language…

Both modeling and imitation training were found to be effective procedures in eliciting imitation of utterances. (ST)

This study examined the differential effects on a learning task of two different types of comprehension measures. (SB)

Suggests several factors to account for the onset of infant-adult joint attention initiated by the infant, and identifies several consequences of infants' understanding of others as intentional subjects, such as verbal development and infants' role in their own enculturation. Contends that infants learn referential gestures not only by imitation…

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…

A review of research on language handicapped, disadvantaged, and other children, indicates that incidental language teaching (natural unstructured interactions between adults and children and which allow adults to transmit new information and give children practice in developing communication skills) is a promising language intervention technique…

The effects of expressive modeling experiences on the observational learning of generative language by children with severe mental retardation was investigated. All six children (aged six-nine) demonstrated observational learning of responses modeled by their peers. Organizing the modeling experiences according to matrix-training principles…

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.…

Forty-five children drawn equally from nursery school, kindergarten, and first grade were administered a nonverbal imitation task, a production task, a comprehension task, and a verbal imitation task. The results of the four tasks support the Temporal Complexity Hypothesis, which states that the components of temporality--order among events (O),…

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 review identifies five themes of child language intervention: (1) development of augmentative and alternative communication systems; (2) provision of language stimulation to take advantage of observational learning; (3) teaching of various language functions; (4) teaching of language as a means of environmental and self-control; and (5) study…
