The recent literature on language intervention has become increasingly focused upon developing treatments that more closely parallel normal language acquisition. However, there have been relatively few reports that directly compare imitative procedures to conversational-interactive interventions. The purpose of the present study was to compare the relative effectiveness of imitative intervention and conversational recast language intervention applied to a wide range of grammatical morpheme and complex sentence targets in 21 children with specific language impairment. The results indicated that although both kinds of treatments were effective in triggering acquisition of most targets, consistently fewer presentations to first spontaneous use were required in the conversational procedure. In addition, the transition from elicited production to generalized spontaneous production was more rapid under conversationinteractive treatment. Finally, although imitation treatment was more effec...

The purpose of the study was to compare the relative effectiveness of imitative treatment and conversational recast treatment in children with language impairment and in a group of children with normal language skills. Language treatment outcomes were compared between a group of older (4.7 to 6.7) specifically-language-impaired (SLI) children and a group of younger (2.2 to 4.2) language-normal (LN) children matched on language levels and on intervention targets. The results indicated: (a) Target acquisition was more rapid under conversational recast treatment for both groups. (b) This outcome held for targets absent initially (in pretreatment sampling and probing) as well as for initially partially mastered targets. (c) SLI children sometimes can learn grammatical structures as efficiently as language-normal children if similar language input is tailored to their specific developmental language levels. Implications of these findings for language treatment strategies with SLI childre...

Purpose The goals of this investigation were to determine whether gains in the use of tense and agreement morphemes by children with specific language impairment (SLI) during a 96-session intervention period would still be evident 1 month following treatment and whether these treatment effects would be greater than those seen in children with SLI receiving otherwise similar treatment that did not emphasize tense and agreement morphemes. Method Thirty-three children with SLI (age 3;0 to 4;8 [years;months]) served as participants. The children participated in 1 of 3 treatment conditions. The conditions emphasized 3rd person singular – s, auxiliary is/are/was, or general language stimulation. The children’s use of 3rd person singular – s, auxiliary is/are/was, and past tense – ed was assessed through probes administered throughout treatment and 1 month later. Results The children in the conditions that targeted 3rd person singular – s and auxiliary is/are/was showed significant gains o...

Purpose The goals of this investigation were to determine whether treatment assists children with specific language impairment (SLI) in the use of grammatical morphemes that mark tense and agreement and whether treatment gains influence the children’s use of other, untreated morphemes. Method Twenty-five children with SLI participated in 96 intervention sessions designed to facilitate the children’s use of third-person singular - s or auxiliary is/are/was . Results The children showed significantly larger gains on the target forms than on control forms (e.g., past tense - ed ) that were monitored but not included in intervention. Along with possible treatment-related generalization across morpheme types, there was also evidence of one morpheme type influencing another when neither was the target of intervention. Conclusions Although the results provide clear evidence for intervention effects, it appeared as if maturational factors also played a role. The findings are discussed in te...

Thirty-one children with specific language impairment participated in 48 intervention sessions designed to assist them in the use of 3rd-person singular - s or auxiliary is/are/was . Gains in the use of these target forms were significantly greater than gains on developmentally comparable morphemes serving as control forms. Untreated verb forms that mark both tense and agreement showed greater change during the intervention period than did past - ed . The findings suggest that by gaining skill in the use of morphemes that mark both tense and agreement, the children were able to identify and acquire other morphemes in the language that mark both of these features. This increase in sensitivity did not appear to apply to forms in the language that express tense only.

ABSTRACTThe aim of this study was to uncover factors accounting for the ability of children with specific language impairment (SLI) to learn agreement morphemes in intervention. Twenty-five children with SLI who participated in a six-month intervention program focused on teaching third person singular -s or auxiliary is/are/was showed a wide range of use of the target morpheme after intervention. Regression analyses showed that age and two factors expected to be related to agreement – the use of noun plural -s and subject/verb constructions prior to intervention – significantly predicted progress in the acquisition of agreement morphemes. In contrast, the pretreatment use of morphemes hypothesized to be unrelated to agreement was not a significant predictor of progress. The results indicate that the ability of children with SLI to learn agreement morphemes relies on their prior ability to use noun plural and subject/verb constructions.

Children with SLI (Specific Language Impairment) display language deficits in the absence of frank neurological lesions, global cognitive deficits or significant clinical hearing loss. Although these children can display disruptions in both receptive and expressive grammar, the intervention literature has been largely focused on expressive deficits. Thus, there are numerous reports in the literature suggesting that expressive language skills can be improved using focused presentation of grammatical targets (cf. conversational recast; Camarata, Nelson & Camarata, 1994), but there have been few investigations addressing the remediation of receptive language skills in SLI for those children with receptive language deficits. The purpose of this study was to examine whether focused grammatical intervention on expressive grammar is associated with growth in receptive language in 21 children with SLI who have receptive language deficits. These children displayed significant growth in recep...
