Abstract
Prospective memory performances of older people are examined by using Virtual Week as a prospective memory task in laboratory. Rendell & Craik (2000) improved at problems in previous studies that materials are too abstract and accidental appearances of targets are lack of predictability, and developed Virtual Week. The task is assumed spending during a day, for example, breakfast, supper, shopping, and going school. In addition, the regulation which is a feature of daily living of repeating the same thing every day is introduced. The condition of task is regular, irregular, and time monitoring. As a result, older people showed good performance under the regular condition.
