title: The communication abilities of 2- to 4-year-old twins.
abstract: The speech and language abilities of pre-school multiple-birth children (MBC) are often reported to be impaired. In this study, teh syntactic, semantic, pragmatic, articulation and phonological skills of 19 sets of MBC were assessed. The comparisons made were between MBC and matched singleton controls, between siblings within multiple-birth sets, and for each multiple-birth child with different conversational partners (sibling versus speech and language therapist). The results indicated that the MBC performed more poorly than the singleton controls on measures of syntax and phonology. Whilst there were quantitative and qualitative similarities between siblings' linguistic abilities, their phonologies were not identical, and the MBC's speech and language changed with different conversational partners. The implications of the results for the existence of 'twin language', choice of language sample for assessment of functional communication and the need for preventive intervention programmes are discussed.
