Three experiments explored different schedules of retrieval practice in young adults, older and individuals with dementia the Alzheimer type. In each experiment, an initial acquisition phase was presented which participants studied or attempted to retrieve response words cues, followed by a later cued-recall test. Experiment 1 produced benefit expanded over equal-interval during acquisition, but this lost final cued recall. Experiments 2 3, received corrective feedback modified spacing schedules. There again no evidence difference between conditions Discussion focuses on potential benefits costs theoretical applied level.
