“…The above‐reviewed studies have focused on children aged 4 and older, so we do not know whether 2‐year‐olds, for example, would also benefit from feedback. There is now ample evidence that children repair their failed communicative attempts even at the preverbal stage (Golinkoff, 1986, 1993; Liszkowski, Carpenter, & Tomasello, in press; Tomasello, Carpenter, & Liszkowski, in press) and often respond to clarification requests in an appropriate manner by the age of 2 (Anselmi, Tomasello, & Acunzo, 1986; Gallagher, 1977; Tomasello, Anselmi, & Farrar, 1984/1985). However, it is not clear that children this young are able to infer from the fact that someone has asked for clarification that their original attempt at reference was not sufficiently informative (as opposed, e.g., to not being heard).…”
