We know that children's early language frequently includes grammatical
errors. How, then, do they manage to recover from the errors and arri
ve at an error-free grammatical system ? Understanding the likely role
of corrections or corrective information has practical consequences f
or children for whom language development may be delayed, such as deaf
children acquiring spoken language. In this paper we consider a type
of corrective mechanism which appears to be operating during the early
language acquisition process. Two experimental studies are described
in which this corrective mechanism was investigated with hearing child
ren, and a strong case is made that corrective information in language
addressed to children does indeed contribute to their language learni
ng processes. Information is also included from a third study, in whic
h some exploratory observations were made on corrective feedback to th
ree oral deaf children.
