AGE-DIFFERENCES IN CONVERSATIONAL SOURCE MONITORING

The present investigation simulated a group conversation in which participants asked( inquirer) and answered (responder) questions, as well as listened to others exchange information. Source (inquirer; responder) identification accuracy was evaluated immediately or after 1 week. Older adults were less adept at source identification, although this difference was reduced with personal (Experiment 2) rather than categorical (Experiment 1) topics. The age difference was independent of explicit memory (cued recall and recognition), suggesting that memory for source and information are separable. Older adults were comparable to younger adults in responder identification but worse at inquirer identification. Responder identification was better than inquirer identification, with the latter dropping to chance at 1 week. Source identification was most accurate when participants were in the responder role; there was little difference between the inquirer and listener roles.
