Generating a recast
Clarke et. al. [1] discuss that "in the adult–child interaction, the adult generates a recast when he or she "....expands, deletes, permutes, or otherwise changes the [child’s utterance] while maintaining significant overlap in meaning". Sometimes, recasts provide a corrective contrast with the child’s immediately prior turn through the provision of an enhanced version of the child’s ill-formed utterance, as in the example below reproduced from Saxton."
"Child: It might get loosed down the plughole
Adult: Lost down the plughole?"
"Equally, some recasts give no clear-cut correction but still offer potential for facilitation of acquisition by providing a structural contrast with an errorless sentence produced by the child as in the following constructed extract, which illustrates an adult expanding the child’s utterance into one that is more complex"[1]:
"Child: That's a big horse. Adult: Yep, that's a big horse with lots of black spots."
"Sometimes, recasts may introduce multiple changes, as in the following example,whereby the adult both expands on and corrects components of the child’s utterance:"[1]
"Child: Why does he that? Adult: Mmm, I am not sure why he does that."
