One oft‐cited problem with teaching speech skills to autistic children isthe failure of the speech to be spontaneous. That is, the children's speech often remains underthe control of the verbal behavior of others rather than underthe control of other nonverbal referents inthe environment. We investigatedthe effectiveness of a time delay procedure to increasethe spontaneous speech of seven autistic children. Initially, the experimenter presented a desired object (e.g., cookie) and immediately modeledthe appropriate response “I want (cookie).” Gradually, asthe child imitatedthe vocalization, the experimenter increasedthe time between presentation of the object andthe modeled vocalization in an attempt to transfer stimulus control of the child's vocalization fromthe experimenter's model tothe object. Results indicated that allthe children learned to request items spontaneously and generalized this behavior across settings, people, situations, and to objects which had not been taught. These results are discussed in relation tothe literature on spontaneous speech, prompting, and generalization.
