An investigation of delayed echoing in a child with autism

Delayed echoing represents one kind of imitative speech which occurs frequently in childhood autism. Previous research has shown that it can be used as a communicative device by children with autism, but less attention has been paid to echoes which are non-communicative. Investigation of these in the recordings of one such child reveals how they are identifiable and how they are differentially organized in comparison with the other forms of talk of which the child is capable. The analysis shows how, for this child, the concerns of delayed echoing and those motivating talk- in-interaction are separate and non-equivalent. Through the ways in which he constructs and co-ordinates these two kinds of involvement, he demonstrates that his principal, enduring concern is with those matters indexed through his echoing.
