The child directed speech of twelve English‐speaking motherswas analyzed in terms of utterance‐level constructions. First, the mothers' utterances were categorized in terms of general constructional categories such as Wh‐questions, copulas and transitives. Second, mothers' utterances within these categories were further specified in terms of the initial words that framed the utterance, item‐based phrases such as Are you …, I'll …, It's …, Let's …, What did … The findings were: (i) overall, only about 15% of all maternal utterances had SVO (...) form (most were questions, imperatives, copulas, and fragments); (ii) 51% of all maternal utterances began with one of 52 item‐based phrases, mostly consisting of two words or morphemes (45% began with one of just 17 words); and (iii) children used many of these same item‐based phrases, in some cases at a rate that correlated highly with their own mother's frequency of use. We suggest that analyses of adult–child linguistic interaction should take into account not just general constructional categories, but also the item‐based constructions that adults and children use and the frequency with which they use them.

In the present study we analyse a sample of Irish Child Directed Speech in terms of item-based constructions and the communicative intents which they express. The study is based on the speech of an Irish native speaker engaged in daily activities with her son (aged 1;9). The findings of the analyses indicate the high degree of lexical specificity attested in the sample; in total 35 item-based frames account for just under 70% of analysed utterances. In most cases there was a (...) one-to-one relationship between item-based frame and communicative intent. However, of particular interest was the clustering of structurally related frames around specific functions. We propose that this relationship highlights the role of communicative intent in the organisation of structural linguistic knowledge. (shrink)
