How do aphasic and normal speaking subjects restate a message in response to feedback?
Seven aphasic and seven normal subjects (Ss) viewed and described 25 cartoon drawings. While Ss described individual pictures the experimenter provided one of three types of feedback: explicit feedback, for example, "Can you tell me anything else about it?"; false feedback, for example, asking a question about another picture; or implicit feedback, for example, "I can't find it." five types of responses (recodings) were tallied. These included deletion, expansion, repetition, revision, and "other communicative behaviors." It was found that (1) the normal Ss used significantly more expansion and deletion than the aphasics; (2) there were no significant differences between the groups for repetition, revision, and "other communicative behaviors"; and (3) the Ss' recodings varied depending on the type of feedback presented.
